[svn-r6411] Purpose: Code cleanup Description: Clean up miscellaneous warnings which have crept into the code. Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD. Adjust gcc compiler flags to be more concise for production mode. Refactor the H5O code so that there is a stronger boundary between code in the H5O package and code in the library which just calls H5O routines. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel and gcc 2.95.4 & gcc 3.2.2 Misc. update: Update MANIFEST if you add or remove any file.

[svn-r329] Changes since 19980324 ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

* Robb Matzke <matzke@llnl.gov>
*
* Purpose: Symbol table functions. The functions that begin with
* `H5G_stab_' don't understand the naming system; they operate
* on a single symbol table at a time.
*
* The functions that begin with `H5G_node_' operate on the leaf
* nodes of a symbol table B-tree. They should be defined in
[svn-r11245] Purpose: Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest

* The remaining functions know how to traverse the group
* directed graph.
*
* Names: Object names are a slash-separated list of components. If
* the name begins with a slash then it's absolute, otherwise
* it's relative ("/foo/bar" is absolute while "foo/bar" is
* relative). Multiple consecutive slashes are treated as
* single slashes and trailing slashes are ignored. The special
* case `/' is the root group. Every file has a root group.
*
* API functions that look up names take a location ID and a
* name. The location ID can be a file ID or a group ID and the
* name can be relative or absolute.
*
* +--------------+----------- +--------------------------------+
* | Location ID | Name | Meaning |

[svn-r178] Changes since 19980127 ---------------------- ./Makefile.in ./config/commence.in With GNU make you can now use `-j' and `-l' options and things get built correctly. I can do a `make -j -l6 test' from a clean hdf5 source tree (after configure) in 45 seconds (8 to build dependencies, 26 to compile everything, and 11 to run the tests). ./src/H5Gnode.c Removed a comment that no longer applies. ./src/H5P.c ./src/H5Pprivate.h ./src/H5Ppublic.h Changed H5Pselect_hyperslab() to H5Pset_hyperslab() and added H5Pget_hyperslab() and H5P_get_hyperslab(). Replaced a couple short memset() calls with a for loop. Removed `if (foo!=NULL)' from around H5MM_xfree() calls. Clear hslab_def when the hyperslab disappears. ./src/H5Tpublic.h Removed trailing enum comma.

* Added `Errors:' field to function prologues.
[svn-r61] ./src/H5.c Changed atexit() to HDatexit(). ./src/H5AC.c Changed qsort() to HDqsort(). ./src/H5B.c Changed memcmp() to HDmemcmp(). ./src/H5E.c ./src/H5M.c Added parentheses around indirect function calls so that checkposix doesn't complain and to advertise that it's an indirect function call. ./src/H5F.c ./src/H5G.c Added errors field to each function prologue to test the script mentioned above. ./src/H5H.c Changed fputc() to HDfputc(). ./src/H5MM.c ./src/H5MMprivate.h The argument for H5MM_xfree() is a pointer to a constant even though the argument to free() isn't. This reduces the number of warnings in other parts of the code but creates a new warning in this file. ./src/H5O.c Plugged a few memory leaks that happen during error handling. ./src/H5Oname.c ./src/debug.c Added `HD' to the beginning of some posix functions.

[svn-r2652] Purpose: Maintainance & performance enhancements Description: Re-arranged header files to protect private symbols better. Changed optimized regular hyperslab I/O to compute the offsets more efficiently from previous method of using matrix operations. Added sequential I/O operations at a more abstract level (at the same level as H5F_arr_read/write), to support the optimized hyperslab I/O. Platforms tested: Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)

[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note.

/* Declare a free list to manage the H5G_t struct */
H5FL_DEFINE(H5G_t);
[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group.

Added tracing support for ragged array object ID's and arrays of pointers. ./src/H5D.c H5Dcreate() will complain if either of the property lists are invalid (instead of using the default). ./src/H5D.c ./src/H5Dprivate.h Split H5Dget_space() into an API and internal function so it can be called from the new ragged array layer. ./src/H5Fistore.c Fixed warnings about unsigned vs. signed comparisons. ./src/H5Flow.c Fixed a warning about a variable being shadowed in the MPI-IO stuff. ./src/H5Iprivate.h ./src/H5Ipublic.h Added the H5_RAGGED atom group. ./src/H5Shyper.c Fixed some freeing-free-memory errors that resulted when certain arrays were freed but the pointers were left in the data structures. I simply set the pointers to null after they were freed. ./src/H5Sprivate.h ./src/H5Sselect.c Split the H5Sselect_hyperslab() function into an API and a private function so it could be called from the ragged array layer. Added H5S_SEL_ERROR and H5S_SEL_N to the switch statements to get rid or compiler warnings. ./src/H5Tconv.c Removed a misleading comment. ./test/bittests.c Fixed a warning about a printf(). ./test/cmpd_dset.c Fixed warnings about unused variables because of test #11 being commented out. ./bin/trace Shortened the right margin for the output to allow room for the `);' at the end of the TRACE() macros.

[svn-r129] Changes since 19970916 ---------------------- ./config/depend.in Fixed backslashes in sed script because the H5Gnode.c dependency info was disappearing. You'll have to rerun config.status to rebuild the Makefiles unless you use gnu make. ./config/conclude.in Also removes emacs backup files, TAGS, and svf backup files. ./config/linux Grouped gcc flags and added provisions for debugging vs. production. ./html/H5.format.html Updated messages 0x0008, 0x0009, and 0x000A. ./html/storage.html Documentation describing storage schemes. ./src/Makefile.in ./test/Makefile.in New source files. ./src/H5A.c ./src/H5Apublic.h ./src/H5C.c Changed VOIDP to void* in a couple places. ./src/H5AC.c ./src/H5ACprivate.h ./src/H5B.c ./src/H5Bprivate.h ./src/H5G.c ./src/H5Gnode.c ./src/H5Gprivate.h ./src/H5H.c ./src/H5O.c Removed `const' from some variables because H5G_node_found() wanted to modify it's udata argument. Removing const there caused it to cascade to these other locations. ./src/H5AC.c ./src/H5ACprivate.h ./src/H5B.c ./src/H5Gnode.c ./src/H5Gstab.c ./src/H5H.c ./src/H5O.c Added an extra argument to H5AC_find_f() and H5AC_protect(). This arg gets passed to the load() method. Also added an extra argument to the H5AC_find() macro. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c Extra argument passed to the sizeof_rkey() method. ./src/H5Fprivate.c ./src/H5Fistore.c (new) Added indexed I/O operations. ./src/H5G.c ./src/H5Gnode.c ./src/H5Gprivate.h Beginning to add H5G_open/close and related bug fixes. ./src/H5Oprivate.h ./src/H5Oistore.c (new) Added the H5O_ISTORE messsage (0x0008) for indexed storage of objects. ./src/H5private.h Added extra braces around both sides of the FUNC_ENTER() and FUNC_LEAVE() macros so FUNC_ENTER() can appear before declarations or after executable statements the second case is used by H5G_namei() to initialize output arguments to sane values before FUNC_ENTER() might return failure. int f () { int decl1; printf ("This happens before FUNC_ENTER()\n"); FUNC_ENTER (...); int another_declaration; ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c Extra arguments for key encoding and decoding. ./src/H5E.c ./src/H5Epublic.h ./src/H5Fistore.c ./src/H5Oistore.c ./src/H5Oprivate.h Indexed, chunked, sparse storage (not ready for general consumption yet). ./src/H5V.c (new) ./src/H5Vprivate.h (new) ./test/hyperslab.c (new) Vector, array, and hyperslab functions. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Fistore.c ./src/H5Gnode.c ./src/H5V.c ./src/H5Vprivate.h ./test/hyperslab.c Added functionality for indexed storage. ./src/H5F.c Fixed problems with seek optimizing. Recommend we disable it until we can implement it in the file/address class since all of HDF5 must be aware of it. ./src/H5O.c Fixed comeent speling erorr :-) ./MANIFEST Added new files. ./config/conclude.in Added the word `Testing' to the test cases. So if a test program is called hyperslab then the make output will contain the line `Testing hyperslab'. ./config/linux The default file I/O library is Posix section 2 on my linux machine so I can do some I/O performance testing. ./src/H5C.c ./src/H5Cprivate.h ./src/H5Cpublic.h Added ability to set size of indexed-storage B-tree. ./src/H5D.c ./src/H5E.c ./src/H5Epublic.h ./src/H5F.c ./src/H5Fprivate.h ./src/H5G.c ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5Gpublic.h ./src/H5Gshad.c ./src/H5Gstab.c ./test/stab.c Changed `directory' to `group' in numerous places. ./src/H5private.h The FILELIB constant can be set on the compile command-line. ./src/istore.c NEW Tests for indexed storage.

[svn-r633] Changes since 19980828 ---------------------- ./RELEASE Updated with important changes I made since the second beta. ./src/H5A.c ./src/H5D.c ./src/H5Dprivate.h ./src/H5G.c ./src/H5Gprivate.h ./src/H5R.c ./src/H5Rprivate.h ./src/H5T.c ./src/H5Tprivate.h Any API function that used to take an `hid_t loc_id' followed by a `const char *name' can now take any type of object for the loc_id as long as the object is somehow associated with a file. Internally, H5G_loc() was modified to return an H5G_entry_t* instead of an H5G_t* so it's more general. Among other things, this allows one to retrieve information about an object like a named type or dataset without knowing the name of the type or dataset: int get_nlinks (hid_t obj) { H5G_stat_t sb; if (H5Gstat(obj, ".", TRUE, &sb)<0) return -1; return sb.nlink; } ./test/gheap.c ./test/istore.c These files needed a couple of changes because they call some of the internal functions whose H5G_t arguments changed to H5G_entry_t. ./src/H5A.c Got rid of all the switch statements for getting symbol table entries for varous objects and replaced them with a call to H5G_loc() allowing attributes to automatically apply to any type of object that belongs to a file. ./test/Makefile.in Moved the ragged array tests from the normal list of tests to the `make timings' target. ./test/ragged.c Added rewrite tests -- rewrite the rows of a dataset changing the number of rows and the length of each row. ./test/mtime.c Added a test that checks that H5Gstat() can be called with a dataset as the first argument. ./src/H5S.c Added #ifdef HAVE_PARALLEL around code to check for the HDF5_MPI_OPT_TYPES environment variable because the global variable that gets set is #ifdef'd. ./bin/release bzip2 uses .bz2 as the file extension.

H5G_entry_t *loc = NULL;
[svn-r329] Changes since 19980324 ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

H5G_t *grp = NULL;
[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

FUNC_ENTER_API(H5Gcreate, FAIL);
[svn-r429] Changes since 19980616 ---------------------- ./html/tracing.html NEW This entire update is to make it possible for the library to print the name, arguments, and return value of every API call without requiring any extra work from developers or app programmers. This file describes how this all works. ./configure.in Added the `--enable-tracing' switch. If you use it then the library will include code to print API function names, argument names and values, and function return values. However, you must then turn on the tracing by setting the HDF5_TRACE environment variable to a file descriptor number. The default is `--disable-tracing' since enabling it causes a slight increase in library size and a slowdown resulting from an extra function call for each API function call (I couldn't even measure the slowdown :-) ./bin/trace NEW A perl script that synchronizes the H5TRACE() macro calls in the *.c files with the function return type and formal argument names and types. If you use GNU make and gcc then this will be done automatically, otherwise just invoke this script with the names of one or more .c files. You could do it by hand to, but encoding argument types is a little tricky at first. ./config/commence.in Added the $(TRACE) macro, which defaults to the no-op. Added -D_POSIX_SOURCE to the compiler command line. ./src/Makefile.in Override the default for $(TRACE). ./config/depend.in Automatically calls $(TRACE) to synchronize the H5TRACE() macros in any source file that changed. As with makefile dependencies, one way to force synchronization of all files is to remove the `.depend' file. ./MANIFEST Added new files. ./src/H5Eprivate.h Modified HRETURN_ERROR() and HRETURN() for tracing. ./src/H5.c ./src/H5private.h This is where the real tracing work really happens, in H5_trace(). ./src/H5A.c ./src/H5D.c ./src/H5G.c ./src/H5P.c ./src/H5S.c ./src/H5Z.c Added H5TRACE() calls to all API functions. You don't really need these changes if you don't want to merge your stuff because they can be generated automatically by going to the hdf5/src directory and saying ../bin/trace *.c ./src/H5T.c Added H5TRACE() calls. Other stuff below. ./src/H5E.c ./src/H5Epublic.h Added H5TRACE() calls. Created a type H5E_auto_t for the `func' argument of H5Eset_auto() and H5Eget_auto() to make those arguments easier to parse for tracing. It should also make it clearer for users that don't know how to read complicated ANSI data types. ./src/H5F.c Added H5TRACE() calls. Changed a couple `uintn' argument types in API functions to `unsigned int' since `uintn' part of the API. Changed a few "can't" and "cant" error messages to "unable to". ./src/H5Ipublic.h Removed H5_DIRECTORY from the H5I_group_t enum. It wasn't used anywhere. ./src/H5Tconv.c Removed an unused label. ./src/H5Fistore.c ./src/H5Oattr.c ./src/H5Odtype.c ./src/H5T.c ./test/dsets.c ./test/dtypes.c Fixed a warning about a variable possibly used before it's initialized. Added __unused__ to turn off some unused argument warnings that pop up when debugging is turned off and optimizations are turned on.

Not fully implemented yet. The test is not actually part of `make test' because we still have some memory problems. ./src/H5E.c ./src/H5Epublic.h Added H5E_RAGGED as a major error number. ./bin/release Checks the MANIFEST file against `svf ls' on systems that have it. ./bin/trace Fixed a bug that caused arguments of type `void *x[]' to not be handled. ./src/H5.c Removed unused variables and changed a couple types to fix compiler warnings. Added tracing support for ragged array object ID's and arrays of pointers. ./src/H5D.c H5Dcreate() will complain if either of the property lists are invalid (instead of using the default). ./src/H5D.c ./src/H5Dprivate.h Split H5Dget_space() into an API and internal function so it can be called from the new ragged array layer. ./src/H5Fistore.c Fixed warnings about unsigned vs. signed comparisons. ./src/H5Flow.c Fixed a warning about a variable being shadowed in the MPI-IO stuff. ./src/H5Iprivate.h ./src/H5Ipublic.h Added the H5_RAGGED atom group. ./src/H5Shyper.c Fixed some freeing-free-memory errors that resulted when certain arrays were freed but the pointers were left in the data structures. I simply set the pointers to null after they were freed. ./src/H5Sprivate.h ./src/H5Sselect.c Split the H5Sselect_hyperslab() function into an API and a private function so it could be called from the ragged array layer. Added H5S_SEL_ERROR and H5S_SEL_N to the switch statements to get rid or compiler warnings. ./src/H5Tconv.c Removed a misleading comment. ./test/bittests.c Fixed a warning about a printf(). ./test/cmpd_dset.c Fixed warnings about unused variables because of test #11 being commented out. ./bin/trace Shortened the right margin for the output to allow room for the `);' at the end of the TRACE() macros.

[svn-r9556] Purpose: Code cleanup & optimization Description: Improve ADF/CGNS benchmark by reducing the number of internal attribute copies made during creations, opens and writes. Added new H5O_iterate() routine for iterating through messages of a certain type in the object header (attributes are the only message currently that can have multiple instances in the object header). Cross-pollinated various minor code cleanups to reduce diffs between branches. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest

hid_t ret_value = FAIL;
[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

[svn-r633] Changes since 19980828 ---------------------- ./RELEASE Updated with important changes I made since the second beta. ./src/H5A.c ./src/H5D.c ./src/H5Dprivate.h ./src/H5G.c ./src/H5Gprivate.h ./src/H5R.c ./src/H5Rprivate.h ./src/H5T.c ./src/H5Tprivate.h Any API function that used to take an `hid_t loc_id' followed by a `const char *name' can now take any type of object for the loc_id as long as the object is somehow associated with a file. Internally, H5G_loc() was modified to return an H5G_entry_t* instead of an H5G_t* so it's more general. Among other things, this allows one to retrieve information about an object like a named type or dataset without knowing the name of the type or dataset: int get_nlinks (hid_t obj) { H5G_stat_t sb; if (H5Gstat(obj, ".", TRUE, &sb)<0) return -1; return sb.nlink; } ./test/gheap.c ./test/istore.c These files needed a couple of changes because they call some of the internal functions whose H5G_t arguments changed to H5G_entry_t. ./src/H5A.c Got rid of all the switch statements for getting symbol table entries for varous objects and replaced them with a call to H5G_loc() allowing attributes to automatically apply to any type of object that belongs to a file. ./test/Makefile.in Moved the ragged array tests from the normal list of tests to the `make timings' target. ./test/ragged.c Added rewrite tests -- rewrite the rows of a dataset changing the number of rows and the length of each row. ./test/mtime.c Added a test that checks that H5Gstat() can be called with a dataset as the first argument. ./src/H5S.c Added #ifdef HAVE_PARALLEL around code to check for the HDF5_MPI_OPT_TYPES environment variable because the global variable that gets set is #ifdef'd. ./bin/release bzip2 uses .bz2 as the file extension.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

[svn-r429] Changes since 19980616 ---------------------- ./html/tracing.html NEW This entire update is to make it possible for the library to print the name, arguments, and return value of every API call without requiring any extra work from developers or app programmers. This file describes how this all works. ./configure.in Added the `--enable-tracing' switch. If you use it then the library will include code to print API function names, argument names and values, and function return values. However, you must then turn on the tracing by setting the HDF5_TRACE environment variable to a file descriptor number. The default is `--disable-tracing' since enabling it causes a slight increase in library size and a slowdown resulting from an extra function call for each API function call (I couldn't even measure the slowdown :-) ./bin/trace NEW A perl script that synchronizes the H5TRACE() macro calls in the *.c files with the function return type and formal argument names and types. If you use GNU make and gcc then this will be done automatically, otherwise just invoke this script with the names of one or more .c files. You could do it by hand to, but encoding argument types is a little tricky at first. ./config/commence.in Added the $(TRACE) macro, which defaults to the no-op. Added -D_POSIX_SOURCE to the compiler command line. ./src/Makefile.in Override the default for $(TRACE). ./config/depend.in Automatically calls $(TRACE) to synchronize the H5TRACE() macros in any source file that changed. As with makefile dependencies, one way to force synchronization of all files is to remove the `.depend' file. ./MANIFEST Added new files. ./src/H5Eprivate.h Modified HRETURN_ERROR() and HRETURN() for tracing. ./src/H5.c ./src/H5private.h This is where the real tracing work really happens, in H5_trace(). ./src/H5A.c ./src/H5D.c ./src/H5G.c ./src/H5P.c ./src/H5S.c ./src/H5Z.c Added H5TRACE() calls to all API functions. You don't really need these changes if you don't want to merge your stuff because they can be generated automatically by going to the hdf5/src directory and saying ../bin/trace *.c ./src/H5T.c Added H5TRACE() calls. Other stuff below. ./src/H5E.c ./src/H5Epublic.h Added H5TRACE() calls. Created a type H5E_auto_t for the `func' argument of H5Eset_auto() and H5Eget_auto() to make those arguments easier to parse for tracing. It should also make it clearer for users that don't know how to read complicated ANSI data types. ./src/H5F.c Added H5TRACE() calls. Changed a couple `uintn' argument types in API functions to `unsigned int' since `uintn' part of the API. Changed a few "can't" and "cant" error messages to "unable to". ./src/H5Ipublic.h Removed H5_DIRECTORY from the H5I_group_t enum. It wasn't used anywhere. ./src/H5Tconv.c Removed an unused label. ./src/H5Fistore.c ./src/H5Oattr.c ./src/H5Odtype.c ./src/H5T.c ./test/dsets.c ./test/dtypes.c Fixed a warning about a variable possibly used before it's initialized. Added __unused__ to turn off some unused argument warnings that pop up when debugging is turned off and optimizations are turned on.

[svn-r9727] Purpose: Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes".

[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

You'll have to rerun config.status to rebuild the Makefiles unless you use gnu make. ./config/conclude.in Also removes emacs backup files, TAGS, and svf backup files. ./config/linux Grouped gcc flags and added provisions for debugging vs. production. ./html/H5.format.html Updated messages 0x0008, 0x0009, and 0x000A. ./html/storage.html Documentation describing storage schemes. ./src/Makefile.in ./test/Makefile.in New source files. ./src/H5A.c ./src/H5Apublic.h ./src/H5C.c Changed VOIDP to void* in a couple places. ./src/H5AC.c ./src/H5ACprivate.h ./src/H5B.c ./src/H5Bprivate.h ./src/H5G.c ./src/H5Gnode.c ./src/H5Gprivate.h ./src/H5H.c ./src/H5O.c Removed `const' from some variables because H5G_node_found() wanted to modify it's udata argument. Removing const there caused it to cascade to these other locations. ./src/H5AC.c ./src/H5ACprivate.h ./src/H5B.c ./src/H5Gnode.c ./src/H5Gstab.c ./src/H5H.c ./src/H5O.c Added an extra argument to H5AC_find_f() and H5AC_protect(). This arg gets passed to the load() method. Also added an extra argument to the H5AC_find() macro. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c Extra argument passed to the sizeof_rkey() method. ./src/H5Fprivate.c ./src/H5Fistore.c (new) Added indexed I/O operations. ./src/H5G.c ./src/H5Gnode.c ./src/H5Gprivate.h Beginning to add H5G_open/close and related bug fixes. ./src/H5Oprivate.h ./src/H5Oistore.c (new) Added the H5O_ISTORE messsage (0x0008) for indexed storage of objects. ./src/H5private.h Added extra braces around both sides of the FUNC_ENTER() and FUNC_LEAVE() macros so FUNC_ENTER() can appear before declarations or after executable statements the second case is used by H5G_namei() to initialize output arguments to sane values before FUNC_ENTER() might return failure. int f () { int decl1; printf ("This happens before FUNC_ENTER()\n"); FUNC_ENTER (...); int another_declaration; ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c Extra arguments for key encoding and decoding. ./src/H5E.c ./src/H5Epublic.h ./src/H5Fistore.c ./src/H5Oistore.c ./src/H5Oprivate.h Indexed, chunked, sparse storage (not ready for general consumption yet). ./src/H5V.c (new) ./src/H5Vprivate.h (new) ./test/hyperslab.c (new) Vector, array, and hyperslab functions. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Fistore.c ./src/H5Gnode.c ./src/H5V.c ./src/H5Vprivate.h ./test/hyperslab.c Added functionality for indexed storage. ./src/H5F.c Fixed problems with seek optimizing. Recommend we disable it until we can implement it in the file/address class since all of HDF5 must be aware of it. ./src/H5O.c Fixed comeent speling erorr :-) ./MANIFEST Added new files. ./config/conclude.in Added the word `Testing' to the test cases. So if a test program is called hyperslab then the make output will contain the line `Testing hyperslab'. ./config/linux The default file I/O library is Posix section 2 on my linux machine so I can do some I/O performance testing. ./src/H5C.c ./src/H5Cprivate.h ./src/H5Cpublic.h Added ability to set size of indexed-storage B-tree. ./src/H5D.c ./src/H5E.c ./src/H5Epublic.h ./src/H5F.c ./src/H5Fprivate.h ./src/H5G.c ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5Gpublic.h ./src/H5Gshad.c ./src/H5Gstab.c ./test/stab.c Changed `directory' to `group' in numerous places. ./src/H5private.h The FILELIB constant can be set on the compile command-line. ./src/istore.c NEW Tests for indexed storage.

[svn-r329] Changes since 19980324 ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

[svn-r529] Changes since 19980722 ---------------------- ./src/H5.c Handle hid_t of type H5_TEMPBUF, arguments usually called tbuf_id.

/*
* Open the group on which to operate. We also create a group ID which
* we can pass to the application-defined operator.
*/
[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

However, since most functions can't take a group ID in place of a file ID yet, there's not a whole lot that the operator can do besides print the name or something. ./test/H5O.c Fixed writing of four uninitialized bytes to the file as part of an object header. ./test/istore.c For some reason, `mpirun -np 1 istore' results in extra arguments on the command line that istore doesn't understand. I'm probably forgetting to call some MPI function in main(). Albert, Kim? So I commented out the `exit(1)' for the time being.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

[svn-r5273] Purpose: New feature Description: Allow H5Glink and H5Gmove to handle links across different locations. Solution: Added H5Glink2 and H5Gmove2 functions with new parameter of destination location. Platforms tested: Linux 2.2(eirene)

[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

The ./test/links program will create a `links.h5' file that demonstrates hard links, soft links, dangling links, and recursive links. A symbolic link is a symbol table entity and doesn't have an object header. It's format is described in H5.format.hml. ./src/H5G.c ./src/H5Gpublic.h ./src/h5ls.c Implemented H5Gstat() and H5Gget_linkval() as documented by Quincey. The `H5G_type_t type' field of `H5G_stat_t' was changed to `int type' because H5G_type_t was already used and the `type' data type should be open-ended. ./src/H5Ffamily.c Removed an incorrect diagnostic message. ./test/big.c Added read/write calls to test partial I/O to big contiguous datasets. With no arguments it writes to a dataset and prints the list of points written which should be redirected to a file. With an argument (the name of a file containing the stdout of a run with no arguments) values are read from the dataset. One would typically say `big >x && big x'.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

FUNC_ENTER_API(H5Gunlink, FAIL);
[svn-r429] Changes since 19980616 ---------------------- ./html/tracing.html NEW This entire update is to make it possible for the library to print the name, arguments, and return value of every API call without requiring any extra work from developers or app programmers. This file describes how this all works. ./configure.in Added the `--enable-tracing' switch. If you use it then the library will include code to print API function names, argument names and values, and function return values. However, you must then turn on the tracing by setting the HDF5_TRACE environment variable to a file descriptor number. The default is `--disable-tracing' since enabling it causes a slight increase in library size and a slowdown resulting from an extra function call for each API function call (I couldn't even measure the slowdown :-) ./bin/trace NEW A perl script that synchronizes the H5TRACE() macro calls in the *.c files with the function return type and formal argument names and types. If you use GNU make and gcc then this will be done automatically, otherwise just invoke this script with the names of one or more .c files. You could do it by hand to, but encoding argument types is a little tricky at first. ./config/commence.in Added the $(TRACE) macro, which defaults to the no-op. Added -D_POSIX_SOURCE to the compiler command line. ./src/Makefile.in Override the default for $(TRACE). ./config/depend.in Automatically calls $(TRACE) to synchronize the H5TRACE() macros in any source file that changed. As with makefile dependencies, one way to force synchronization of all files is to remove the `.depend' file. ./MANIFEST Added new files. ./src/H5Eprivate.h Modified HRETURN_ERROR() and HRETURN() for tracing. ./src/H5.c ./src/H5private.h This is where the real tracing work really happens, in H5_trace(). ./src/H5A.c ./src/H5D.c ./src/H5G.c ./src/H5P.c ./src/H5S.c ./src/H5Z.c Added H5TRACE() calls to all API functions. You don't really need these changes if you don't want to merge your stuff because they can be generated automatically by going to the hdf5/src directory and saying ../bin/trace *.c ./src/H5T.c Added H5TRACE() calls. Other stuff below. ./src/H5E.c ./src/H5Epublic.h Added H5TRACE() calls. Created a type H5E_auto_t for the `func' argument of H5Eset_auto() and H5Eget_auto() to make those arguments easier to parse for tracing. It should also make it clearer for users that don't know how to read complicated ANSI data types. ./src/H5F.c Added H5TRACE() calls. Changed a couple `uintn' argument types in API functions to `unsigned int' since `uintn' part of the API. Changed a few "can't" and "cant" error messages to "unable to". ./src/H5Ipublic.h Removed H5_DIRECTORY from the H5I_group_t enum. It wasn't used anywhere. ./src/H5Tconv.c Removed an unused label. ./src/H5Fistore.c ./src/H5Oattr.c ./src/H5Odtype.c ./src/H5T.c ./test/dsets.c ./test/dtypes.c Fixed a warning about a variable possibly used before it's initialized. Added __unused__ to turn off some unused argument warnings that pop up when debugging is turned off and optimizations are turned on.

/* Unlink */
[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

[svn-r633] Changes since 19980828 ---------------------- ./RELEASE Updated with important changes I made since the second beta. ./src/H5A.c ./src/H5D.c ./src/H5Dprivate.h ./src/H5G.c ./src/H5Gprivate.h ./src/H5R.c ./src/H5Rprivate.h ./src/H5T.c ./src/H5Tprivate.h Any API function that used to take an `hid_t loc_id' followed by a `const char *name' can now take any type of object for the loc_id as long as the object is somehow associated with a file. Internally, H5G_loc() was modified to return an H5G_entry_t* instead of an H5G_t* so it's more general. Among other things, this allows one to retrieve information about an object like a named type or dataset without knowing the name of the type or dataset: int get_nlinks (hid_t obj) { H5G_stat_t sb; if (H5Gstat(obj, ".", TRUE, &sb)<0) return -1; return sb.nlink; } ./test/gheap.c ./test/istore.c These files needed a couple of changes because they call some of the internal functions whose H5G_t arguments changed to H5G_entry_t. ./src/H5A.c Got rid of all the switch statements for getting symbol table entries for varous objects and replaced them with a call to H5G_loc() allowing attributes to automatically apply to any type of object that belongs to a file. ./test/Makefile.in Moved the ragged array tests from the normal list of tests to the `make timings' target. ./test/ragged.c Added rewrite tests -- rewrite the rows of a dataset changing the number of rows and the length of each row. ./test/mtime.c Added a test that checks that H5Gstat() can be called with a dataset as the first argument. ./src/H5S.c Added #ifdef HAVE_PARALLEL around code to check for the HDF5_MPI_OPT_TYPES environment variable because the global variable that gets set is #ifdef'd. ./bin/release bzip2 uses .bz2 as the file extension.

[svn-r876] Changes since 19981102 ---------------------- ./bin/snapshot Made same fix as for the release script yesterday. ./src/H5D.c ./src/H5Dprivate.h ./src/H5G.c ./src/H5Gprivate.h ./src/H5Gpublic.h ./src/H5O.c ./src/H5Oprivate.h ./src/H5RA.c ./src/H5RAprivate.h ./src/H5T.c ./src/H5Tprivate.h Improved object type checking. Instead of determining the object type by trying to open each of the possible types, we keep a table of associations between object type number (like H5G_GROUP, H5G_DATASET, H5D_TYPE, and H5D_RAGGED) and an `isa' function that returns true if the object header has the right messages to make the object a particular type. This mechanism also allows specialization of object types by permitting an object to satisfy more than one `isa' function. Added `isa' functions for groups, datasets, ragged arrays, and committed data types. ./src/H5config.h.in Added HAVE_STAT_ST_BLOCKS. I thought this had already been added, but apparently not. ./tools/h5ls.c Removed system include files since they're already included by H5private.h and since I wasn't including them portably anyway. By default, 1-byte integer types are printed as integer values instead of ASCII characters. However, the `-s' or `--string' command-line switch causes the data to be interpretted as ASCII. String data types are always printed as character data. Ragged arrays are now identified as ragged arrays and h5ls doesn't descend into the group automatically. This uses the new object type specialization stuff. ./tools/h5tools.c ./tools/h5tools.h Added the ability to print 1-byte integer types as either ASCII or numeric data instead of always ASCII. The default is to print as numeric data.

Added tracing support for ragged array object ID's and arrays of pointers. ./src/H5D.c H5Dcreate() will complain if either of the property lists are invalid (instead of using the default). ./src/H5D.c ./src/H5Dprivate.h Split H5Dget_space() into an API and internal function so it can be called from the new ragged array layer. ./src/H5Fistore.c Fixed warnings about unsigned vs. signed comparisons. ./src/H5Flow.c Fixed a warning about a variable being shadowed in the MPI-IO stuff. ./src/H5Iprivate.h ./src/H5Ipublic.h Added the H5_RAGGED atom group. ./src/H5Shyper.c Fixed some freeing-free-memory errors that resulted when certain arrays were freed but the pointers were left in the data structures. I simply set the pointers to null after they were freed. ./src/H5Sprivate.h ./src/H5Sselect.c Split the H5Sselect_hyperslab() function into an API and a private function so it could be called from the ragged array layer. Added H5S_SEL_ERROR and H5S_SEL_N to the switch statements to get rid or compiler warnings. ./src/H5Tconv.c Removed a misleading comment. ./test/bittests.c Fixed a warning about a printf(). ./test/cmpd_dset.c Fixed warnings about unused variables because of test #11 being commented out. ./bin/trace Shortened the right margin for the output to allow room for the `);' at the end of the TRACE() macros.

[svn-r633] Changes since 19980828 ---------------------- ./RELEASE Updated with important changes I made since the second beta. ./src/H5A.c ./src/H5D.c ./src/H5Dprivate.h ./src/H5G.c ./src/H5Gprivate.h ./src/H5R.c ./src/H5Rprivate.h ./src/H5T.c ./src/H5Tprivate.h Any API function that used to take an `hid_t loc_id' followed by a `const char *name' can now take any type of object for the loc_id as long as the object is somehow associated with a file. Internally, H5G_loc() was modified to return an H5G_entry_t* instead of an H5G_t* so it's more general. Among other things, this allows one to retrieve information about an object like a named type or dataset without knowing the name of the type or dataset: int get_nlinks (hid_t obj) { H5G_stat_t sb; if (H5Gstat(obj, ".", TRUE, &sb)<0) return -1; return sb.nlink; } ./test/gheap.c ./test/istore.c These files needed a couple of changes because they call some of the internal functions whose H5G_t arguments changed to H5G_entry_t. ./src/H5A.c Got rid of all the switch statements for getting symbol table entries for varous objects and replaced them with a call to H5G_loc() allowing attributes to automatically apply to any type of object that belongs to a file. ./test/Makefile.in Moved the ragged array tests from the normal list of tests to the `make timings' target. ./test/ragged.c Added rewrite tests -- rewrite the rows of a dataset changing the number of rows and the length of each row. ./test/mtime.c Added a test that checks that H5Gstat() can be called with a dataset as the first argument. ./src/H5S.c Added #ifdef HAVE_PARALLEL around code to check for the HDF5_MPI_OPT_TYPES environment variable because the global variable that gets set is #ifdef'd. ./bin/release bzip2 uses .bz2 as the file extension.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

The `H5G_type_t type' field of `H5G_stat_t' was changed to `int type' because H5G_type_t was already used and the `type' data type should be open-ended. ./src/H5Ffamily.c Removed an incorrect diagnostic message. ./test/big.c Added read/write calls to test partial I/O to big contiguous datasets. With no arguments it writes to a dataset and prints the list of points written which should be redirected to a file. With an argument (the name of a file containing the stdout of a run with no arguments) values are read from the dataset. One would typically say `big >x && big x'.

[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.

Not fully implemented yet. The test is not actually part of `make test' because we still have some memory problems. ./src/H5E.c ./src/H5Epublic.h Added H5E_RAGGED as a major error number. ./bin/release Checks the MANIFEST file against `svf ls' on systems that have it. ./bin/trace Fixed a bug that caused arguments of type `void *x[]' to not be handled. ./src/H5.c Removed unused variables and changed a couple types to fix compiler warnings. Added tracing support for ragged array object ID's and arrays of pointers. ./src/H5D.c H5Dcreate() will complain if either of the property lists are invalid (instead of using the default). ./src/H5D.c ./src/H5Dprivate.h Split H5Dget_space() into an API and internal function so it can be called from the new ragged array layer. ./src/H5Fistore.c Fixed warnings about unsigned vs. signed comparisons. ./src/H5Flow.c Fixed a warning about a variable being shadowed in the MPI-IO stuff. ./src/H5Iprivate.h ./src/H5Ipublic.h Added the H5_RAGGED atom group. ./src/H5Shyper.c Fixed some freeing-free-memory errors that resulted when certain arrays were freed but the pointers were left in the data structures. I simply set the pointers to null after they were freed. ./src/H5Sprivate.h ./src/H5Sselect.c Split the H5Sselect_hyperslab() function into an API and a private function so it could be called from the ragged array layer. Added H5S_SEL_ERROR and H5S_SEL_N to the switch statements to get rid or compiler warnings. ./src/H5Tconv.c Removed a misleading comment. ./test/bittests.c Fixed a warning about a printf(). ./test/cmpd_dset.c Fixed warnings about unused variables because of test #11 being commented out. ./bin/trace Shortened the right margin for the output to allow room for the `);' at the end of the TRACE() macros.

[svn-r633] Changes since 19980828 ---------------------- ./RELEASE Updated with important changes I made since the second beta. ./src/H5A.c ./src/H5D.c ./src/H5Dprivate.h ./src/H5G.c ./src/H5Gprivate.h ./src/H5R.c ./src/H5Rprivate.h ./src/H5T.c ./src/H5Tprivate.h Any API function that used to take an `hid_t loc_id' followed by a `const char *name' can now take any type of object for the loc_id as long as the object is somehow associated with a file. Internally, H5G_loc() was modified to return an H5G_entry_t* instead of an H5G_t* so it's more general. Among other things, this allows one to retrieve information about an object like a named type or dataset without knowing the name of the type or dataset: int get_nlinks (hid_t obj) { H5G_stat_t sb; if (H5Gstat(obj, ".", TRUE, &sb)<0) return -1; return sb.nlink; } ./test/gheap.c ./test/istore.c These files needed a couple of changes because they call some of the internal functions whose H5G_t arguments changed to H5G_entry_t. ./src/H5A.c Got rid of all the switch statements for getting symbol table entries for varous objects and replaced them with a call to H5G_loc() allowing attributes to automatically apply to any type of object that belongs to a file. ./test/Makefile.in Moved the ragged array tests from the normal list of tests to the `make timings' target. ./test/ragged.c Added rewrite tests -- rewrite the rows of a dataset changing the number of rows and the length of each row. ./test/mtime.c Added a test that checks that H5Gstat() can be called with a dataset as the first argument. ./src/H5S.c Added #ifdef HAVE_PARALLEL around code to check for the HDF5_MPI_OPT_TYPES environment variable because the global variable that gets set is #ifdef'd. ./bin/release bzip2 uses .bz2 as the file extension.

[svn-r11245] Purpose: Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult.

2005-08-14 04:53:35 +08:00
[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

Added tracing support for ragged array object ID's and arrays of pointers. ./src/H5D.c H5Dcreate() will complain if either of the property lists are invalid (instead of using the default). ./src/H5D.c ./src/H5Dprivate.h Split H5Dget_space() into an API and internal function so it can be called from the new ragged array layer. ./src/H5Fistore.c Fixed warnings about unsigned vs. signed comparisons. ./src/H5Flow.c Fixed a warning about a variable being shadowed in the MPI-IO stuff. ./src/H5Iprivate.h ./src/H5Ipublic.h Added the H5_RAGGED atom group. ./src/H5Shyper.c Fixed some freeing-free-memory errors that resulted when certain arrays were freed but the pointers were left in the data structures. I simply set the pointers to null after they were freed. ./src/H5Sprivate.h ./src/H5Sselect.c Split the H5Sselect_hyperslab() function into an API and a private function so it could be called from the ragged array layer. Added H5S_SEL_ERROR and H5S_SEL_N to the switch statements to get rid or compiler warnings. ./src/H5Tconv.c Removed a misleading comment. ./test/bittests.c Fixed a warning about a printf(). ./test/cmpd_dset.c Fixed warnings about unused variables because of test #11 being commented out. ./bin/trace Shortened the right margin for the output to allow room for the `);' at the end of the TRACE() macros.

[svn-r633] Changes since 19980828 ---------------------- ./RELEASE Updated with important changes I made since the second beta. ./src/H5A.c ./src/H5D.c ./src/H5Dprivate.h ./src/H5G.c ./src/H5Gprivate.h ./src/H5R.c ./src/H5Rprivate.h ./src/H5T.c ./src/H5Tprivate.h Any API function that used to take an `hid_t loc_id' followed by a `const char *name' can now take any type of object for the loc_id as long as the object is somehow associated with a file. Internally, H5G_loc() was modified to return an H5G_entry_t* instead of an H5G_t* so it's more general. Among other things, this allows one to retrieve information about an object like a named type or dataset without knowing the name of the type or dataset: int get_nlinks (hid_t obj) { H5G_stat_t sb; if (H5Gstat(obj, ".", TRUE, &sb)<0) return -1; return sb.nlink; } ./test/gheap.c ./test/istore.c These files needed a couple of changes because they call some of the internal functions whose H5G_t arguments changed to H5G_entry_t. ./src/H5A.c Got rid of all the switch statements for getting symbol table entries for varous objects and replaced them with a call to H5G_loc() allowing attributes to automatically apply to any type of object that belongs to a file. ./test/Makefile.in Moved the ragged array tests from the normal list of tests to the `make timings' target. ./test/ragged.c Added rewrite tests -- rewrite the rows of a dataset changing the number of rows and the length of each row. ./test/mtime.c Added a test that checks that H5Gstat() can be called with a dataset as the first argument. ./src/H5S.c Added #ifdef HAVE_PARALLEL around code to check for the HDF5_MPI_OPT_TYPES environment variable because the global variable that gets set is #ifdef'd. ./bin/release bzip2 uses .bz2 as the file extension.

H5G_entry_t *loc = NULL;
[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.
2002-08-09 00:52:55 +08:00
int ret_value;
[svn-r11245] Purpose: Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
2005-08-14 04:53:35 +08:00
[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

FUNC_ENTER_API(H5Gget_comment, FAIL);
[svn-r537] Changes since 19980722 ---------------------- ./src/H5A.c ./src/H5Apublic.h ./test/tattr.c Switched the order of the second and third argument of H5Aget_name() to make it consistent with other functions that take buffers and buffer sizes. ./src/H5G.c ./src/H5Gpublic.h ./src/H5Gprivate.h The H5Gget_comment() function returns the size of the comment including the null terminator. If the object has no comment then zero is returned. If an error occurs then a negative value is returned. ./MANIFEST ./tools/Makefile.in ./tools/h5tools.h [NEW] ./tools/h5dump.c [NEW] Created a library for printing values of datasets in a way that looks nice. It's not done yet, but I needed it for debugging the contents of files from Jim Reus. ./tools/h5ls.c Added the `-d' and `--dump' options which cause the contents of a dataset to be printed. Added `-w N' and `--width=N' options to control how wide the raw data output should be. If you want single-column output then say `-w1'. Printing dataset values can now handle datasets of any integer or floating point atomic type. As a special case, integers which are one byte wide are treated a character strings for now. Sample output: $ h5ls --dump --width=60 banana.hdf ARCHIVE 0:0:0:744 Dataset {52/Inf} Data: (0) "U struct complex { double R; double I; };\012V" (43) " double;\012" U 0:0:0:2500 Dataset {256/512} Data: printing of compound data types is not implemented yet V 0:0:0:3928 Dataset {256/512} Data: (0) 0, 0.015625, 0.03125, 0.046875, 0.0625, (5) 0.078125, 0.09375, 0.109375, 0.125, 0.140625, (10) 0.15625, 0.171875, 0.1875, 0.203125, 0.21875, (15) 0.234375, 0.25, 0.265625, 0.28125, 0.296875, ...

[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines.

[svn-r7917] Purpose: Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)

Instead of determining the object type by trying to open each of the possible types, we keep a table of associations between object type number (like H5G_GROUP, H5G_DATASET, H5D_TYPE, and H5D_RAGGED) and an `isa' function that returns true if the object header has the right messages to make the object a particular type. This mechanism also allows specialization of object types by permitting an object to satisfy more than one `isa' function. Added `isa' functions for groups, datasets, ragged arrays, and committed data types. ./src/H5config.h.in Added HAVE_STAT_ST_BLOCKS. I thought this had already been added, but apparently not. ./tools/h5ls.c Removed system include files since they're already included by H5private.h and since I wasn't including them portably anyway. By default, 1-byte integer types are printed as integer values instead of ASCII characters. However, the `-s' or `--string' command-line switch causes the data to be interpretted as ASCII. String data types are always printed as character data. Ragged arrays are now identified as ragged arrays and h5ls doesn't descend into the group automatically. This uses the new object type specialization stuff. ./tools/h5tools.c ./tools/h5tools.h Added the ability to print 1-byte integer types as either ASCII or numeric data instead of always ASCII. The default is to print as numeric data.

[svn-r329] Changes since 19980324 ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

[svn-r4355] Purpose: Code cleanup (sorta) Description: When the first versions of the HDF5 library were designed, I remembered vividly the difficulties of porting code from a 32-bit platform to a 16-bit platform and asked that people use intn & uintn instead of int & unsigned int, respectively. However, in hindsight, this was overkill and unnecessary since we weren't going to be porting the HDF5 library to 16-bit architectures. Currently, the extra uintn & intn typedefs are causing problems for users who'd like to include both the HDF5 and HDF4 header files in one source module (like Kent's h4toh5 library). Solution: Changed the uintn & intn's to unsigned and int's respectively. Platforms tested: FreeBSD 4.4 (hawkwind)

[svn-r5467] Purpose: Code cleanup. Description: Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros equivalents in the SAF library and adapted them to our library. I added an additional macro which is equivalent to FUNC_ENTER: FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but none of the library or interface initialization code. This is to be used _only_ for static functions and those which explicitly cannot have the library or interface initialization code enabled (like the API termination routines, etc.). This allowed many more of the functions in the library [but not all yet :-(] to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs. It also reduced the size of the library and executables (by cutting out a bunch of code which was never executed), I'll e-mail the exact results when I've finished editing it. Platforms tested: IRIX64 6.5 (modi4)
2002-05-29 02:17:12 +08:00
[svn-r7917] Purpose: Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)

Instead of registering an atexit() function for every interface in some haphazard order we just register one: H5_term_library() which then calls the H5*_term_interface() functions in a well-defined order. If the library is closed and then reopened repeatedly by calling H5close() and H5open() in a loop we only add one copy of the library termination functions with atexit(). Termination is a two-step process in order to help detect programming errors that would cause an infinite loop caused by the termination of one interface waking up some other previously terminated interface. The first step terminates the interface and *marks it as unusable*. After all interfaces are terminated then we mark them all as usable again. The FUNC_ENTER() macro has been modified to return failure or to dump core (depending on whether NDEBUG is defined) if we try to call an interface while it's shutting down. ./src/H5.c The H5dont_atexit() function returns failure if it's called more than once or if it's called too late. However, the error stack is not automatically printed on failure because the library might not be initialized yet ./test/chunk.c ./test/flush1.c ./test/flush2.c ./test/iopipe.c ./test/overhead.c ./test/ragged.c Changed the extra cast for Win32 so we do floating point division again -- it was just confusion about precedence and associativity of casting and the C coercion rules. Removed extra carriage returns inserted by broken operating system. ./src/H5Ffamily.c Fixed an bug where H5F_fam_write() lowered the EOF marker for one of the family members causing H5F_fam_read() to read zeros. ./test/h5test.h [NEW] ./test/h5test.c [NEW] ./test/Makefile.in ./test/bittests.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Support library for test files. This isn't done yet but Katie's contractions are ~10 minutes apart so I figured I better back this stuff up just in case I'm not here next week... Eventually all test files will understand HDF5_DRIVER to name the low level file driver and parameters so we can easily test various drivers. They will also understand HDF5_PREFIX to prepend to the beginning of file names which is necessary for testing ROMIO with various drivers. Also, the cleanup function will know how to use the file name prefix and will understand different file driver naming schemes like file families. I'm not sure they'll understand the `gsf:' type prefixes yet. Note, the external test is completely commented out because I'm in the middle of modifying it. It will still compile and run but it doesn't test anything at the moment.

/* Mark closed */
[svn-r8731] Purpose: Code cleanup & minor optimization Description: Re-work the way interface initialization routines are specified in the library to avoid the overhead of checking for them in routines where there is no interface initialization routine. This cleans up warnings with gcc 3.4, reduces the library binary size a bit (about 2-3%) and should speedup the library's execution slightly.

[svn-r914] Changes since 19981113 ---------------------- ./config/conclude.in ./test/Makefile.in ./tools/Makefile.in The Makefile $TESTS variable has finally been split into $TEST_PROGS and $TEST_SCRIPTS with the latter being the names of shell scripts that need to be run with `/bin/sh'.

[svn-r329] Changes since 19980324 ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

Instead of determining the object type by trying to open each of the possible types, we keep a table of associations between object type number (like H5G_GROUP, H5G_DATASET, H5D_TYPE, and H5D_RAGGED) and an `isa' function that returns true if the object header has the right messages to make the object a particular type. This mechanism also allows specialization of object types by permitting an object to satisfy more than one `isa' function. Added `isa' functions for groups, datasets, ragged arrays, and committed data types. ./src/H5config.h.in Added HAVE_STAT_ST_BLOCKS. I thought this had already been added, but apparently not. ./tools/h5ls.c Removed system include files since they're already included by H5private.h and since I wasn't including them portably anyway. By default, 1-byte integer types are printed as integer values instead of ASCII characters. However, the `-s' or `--string' command-line switch causes the data to be interpretted as ASCII. String data types are always printed as character data. Ragged arrays are now identified as ragged arrays and h5ls doesn't descend into the group automatically. This uses the new object type specialization stuff. ./tools/h5tools.c ./tools/h5tools.h Added the ability to print 1-byte integer types as either ASCII or numeric data instead of always ASCII. The default is to print as numeric data.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.

I can do a `make -j -l6 test' from a clean hdf5 source tree (after configure) in 45 seconds (8 to build dependencies, 26 to compile everything, and 11 to run the tests). ./src/H5Gnode.c Removed a comment that no longer applies. ./src/H5P.c ./src/H5Pprivate.h ./src/H5Ppublic.h Changed H5Pselect_hyperslab() to H5Pset_hyperslab() and added H5Pget_hyperslab() and H5P_get_hyperslab(). Replaced a couple short memset() calls with a for loop. Removed `if (foo!=NULL)' from around H5MM_xfree() calls. Clear hslab_def when the hyperslab disappears. ./src/H5Tpublic.h Removed trailing enum comma.

[svn-r25] ./src/H5AC.c We sort the cache before a complete flush because it might be more efficient to write things back to disk in order of increasing address. If you want the old way then undef the SORT_BY_ADDR constant at the top of H5AC.c I haven't determined which systems and I/O libraries this helps or hurts. (This is currently off because of a bug I need to track down that causes qsort() to run for a really long time). ./src/H5B.c Fixed a couple more bugs. ./src/H5Eprivate.h ./src/H5Eproto.h Added major H5E_DIRECTORY and minor H5E_EXISTS, H5E_COMPLEN. ./src/H5G.c Added directory-aware functions. The heap and B-tree are created when a directory is created instead of when the first symbol is added. This simplifies symbol table entry caching for the directory since the cached value never changes now. ./src/H5Gnode.c ./src/H5Gprivate.h Fine tuned the B-tree K values for symbol tables assuming an average number of symbols is about 100 per directory. The tuning minimizes storage space. Fixed a return value in H5G_node_cmp(). ./src/H5H.c ./src/H5Hprivate.h Moved some macros the the header file. ./src/H5O.c ./src/H5Ocont.c ./src/H5Onull.c ./src/H5Ostab.c Changed the arguments for the decode method for messages. The second argument is the raw message size. Added a class variable for native message size. Added H5O_reset() to free memory used internally by a message. ./src/H5Oname.c NEW ./src/H5Oprivate.h ./src/Makefile The object name message. ./src/hdf5port.h Added defn for HDstrdup()

[svn-r329] Changes since 19980324 ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

[svn-r7917] Purpose: Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)

FUNC_ENTER_NOAPI_NOINIT_NOFUNC(H5G_component);
[svn-r5467] Purpose: Code cleanup. Description: Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros equivalents in the SAF library and adapted them to our library. I added an additional macro which is equivalent to FUNC_ENTER: FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but none of the library or interface initialization code. This is to be used _only_ for static functions and those which explicitly cannot have the library or interface initialization code enabled (like the API termination routines, etc.). This allowed many more of the functions in the library [but not all yet :-(] to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs. It also reduced the size of the library and executables (by cutting out a bunch of code which was never executed), I'll e-mail the exact results when I've finished editing it. Platforms tested: IRIX64 6.5 (modi4)

[svn-r11245] Purpose: Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest

[svn-r7917] Purpose: Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)

[svn-r7377] Purpose: Bug fix Description: Linking and unlinking objects with multiple internal and/or trailing '/'s was not handled well in the library.

* Function: H5G_namei
*
* Purpose: Translates a name to a symbol table entry.
*
* If the specified name can be fully resolved, then this
* function returns the symbol table entry for the named object
* through the OBJ_ENT argument. The symbol table entry for the
* group containing the named object is returned through the
* GRP_ENT argument if it is non-null. However, if the name
* refers to the root object then the GRP_ENT will be
* initialized with an undefined object header address. The
* REST argument, if present, will point to the null terminator
* of NAME.
*
* If the specified name cannot be fully resolved, then OBJ_ENT
* is initialized with the undefined object header address. The
* REST argument will point into the NAME argument to the start
* of the component that could not be located. The GRP_ENT will
* contain the entry for the symbol table that was being
* searched at the time of the failure and will have an
* undefined object header address if the search failed at the
* root object. For instance, if NAME is `/foo/bar/baz' and the

This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

* Every file has a root group whose name is `/'. Components of
* a name are separated from one another by one or more slashes
* (/). Slashes at the end of a name are ignored. If the name
* begins with a slash then the search begins at the root group
* of the file containing LOC_ENT. Otherwise it begins at
* LOC_ENT. The component `.' is a no-op, but `..' is not
* understood by this function (unless it appears as an entry in
* the symbol table).

The ./test/links program will create a `links.h5' file that demonstrates hard links, soft links, dangling links, and recursive links. A symbolic link is a symbol table entity and doesn't have an object header. It's format is described in H5.format.hml. ./src/H5G.c ./src/H5Gpublic.h ./src/h5ls.c Implemented H5Gstat() and H5Gget_linkval() as documented by Quincey. The `H5G_type_t type' field of `H5G_stat_t' was changed to `int type' because H5G_type_t was already used and the `type' data type should be open-ended. ./src/H5Ffamily.c Removed an incorrect diagnostic message. ./test/big.c Added read/write calls to test partial I/O to big contiguous datasets. With no arguments it writes to a dataset and prints the list of points written which should be redirected to a file. With an argument (the name of a file containing the stdout of a run with no arguments) values are read from the dataset. One would typically say `big >x && big x'.

[svn-r745] Changes since 19981002 ---------------------- ./doc/html/H5.format.html ./src/H5HG.c Fixed a bug in the global heap that caused H5HG_read() to write past the end of the buffer in certain cases. ./test/big.c The test is skipped if hdf5 was configured with `--disable-hsizet'. ./src/H5Ofill.c Data type conversions are implemented for the fill value. ./src/H5.c Tracing prints one of H5P_FILE_CREATE, H5P_FILE_ACCESS, H5P_DATASET_CREATE, H5P_DATASET_XFER, or H5P_MOUNT instead of the more cryptic H5I_TEMPLATE_* constants. ./src/H5D.c Removed prototype for H5D_find_name(). ./src/H5I.c The GROUP_MASK and ID_MASK are both calculated from GROUP_BITS instead of being set by hand. We don't use the sign bit of hid_t; all valid hid_t values are positive so we can say things like `if ((file=H5Fopen(...))<0)'. Changed `(int)pow(2.0,x)' to `1<<x' so we don't have to worry about rounding. Fixed H5I_get_type() so it doesn't always fail an assertion. ./src/H5E.c ./src/H5Epublic.h Added minor error H5E_MOUNT ./src/H5F.c ./src/H5Fprivate.h Added H5Fmount() and H5Funmount(). Mounting and unmounting works as documented but some of the other things aren't implemented yet, the biggest being current working groups always acting on the root of the mount tree, and H5Fclose() closing the entire tree. The rest of the stuff will be added shortly... ./src/H5P.c ./src/H5Ppublic.h Added the H5P_MOUNT property list but haven't implemented any particular properties for it yet. ./src/H5Gstab.c Hard links across files return an error instead of failing an assertion.

[svn-r178] Changes since 19980127 ---------------------- ./Makefile.in ./config/commence.in With GNU make you can now use `-j' and `-l' options and things get built correctly. I can do a `make -j -l6 test' from a clean hdf5 source tree (after configure) in 45 seconds (8 to build dependencies, 26 to compile everything, and 11 to run the tests). ./src/H5Gnode.c Removed a comment that no longer applies. ./src/H5P.c ./src/H5Pprivate.h ./src/H5Ppublic.h Changed H5Pselect_hyperslab() to H5Pset_hyperslab() and added H5Pget_hyperslab() and H5P_get_hyperslab(). Replaced a couple short memset() calls with a for loop. Removed `if (foo!=NULL)' from around H5MM_xfree() calls. Clear hslab_def when the hyperslab disappears. ./src/H5Tpublic.h Removed trailing enum comma.

* Robb Matzke, 2002-03-28
* The component name buffer on the stack has been replaced by
* a dynamically allocated buffer on the heap in order to
* remove limitations on the length of a name component.
* There are two reasons that the buffer pointer is global:
* (1) We want to be able to reuse the buffer without
* allocating and freeing it each time this function is
* called.
* (2) We need to be able to free it from H5G_term_interface()
* when the library terminates.

* Modified to deep copies of symbol table entries

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

With no arguments it writes to a dataset and prints the list of points written which should be redirected to a file. With an argument (the name of a file containing the stdout of a run with no arguments) values are read from the dataset. One would typically say `big >x && big x'.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

I added an additional macro which is equivalent to FUNC_ENTER: FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but none of the library or interface initialization code. This is to be used _only_ for static functions and those which explicitly cannot have the library or interface initialization code enabled (like the API termination routines, etc.). This allowed many more of the functions in the library [but not all yet :-(] to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs. It also reduced the size of the library and executables (by cutting out a bunch of code which was never executed), I'll e-mail the exact results when I've finished editing it.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

[svn-r329] Changes since 19980324 ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

[svn-r1568] Changes since 19990730 ---------------------- This extensive change is the virtual file layer implementation. I've ported and tested the sec2, family, and core drivers and only ported the mpio driver (Albert will test it). So if you need MPIO I would recommend sticking with the previous version for a while. You will get a few compile warnings about split and stdio drivers not being implemented and possibly tracing information not inserted in some of the drivers. You can safely ignore them but I plan to fix them. I'm still working on the split driver because I just realized that it needs a part of the VFL that isn't written yet. Documentation is being updated also because there were some minor changes (mostly just name changes). It should be available on my web site later this week. ./MANIFEST ./src/Makefile.in ./src/hdf5.h ./src/H5Flow.c [REMOVED] ./src/H5Fstdio.c [REMOVED] ./src/H5Fsec2.c [REMOVED] ./src/H5Fsplit.c [REMOVED] ./src/H5Fmpio.c [REMOVED] ./src/H5Ffamily.c [REMOVED] ./src/H5Fcore.c [REMOVED] ./src/H5MFpublic.h [REMOVED] ./src/H5FD.c [NEW] ./src/H5FDcore.c [NEW] ./src/H5FDcore.h [NEW] ./src/H5FDfamily.c [NEW] ./src/H5FDfamily.h [NEW] ./src/H5FDmpio.c [NEW] ./src/H5FDmpio.h [NEW] ./src/H5FDprivate.h [NEW] ./src/H5FDpublic.h [NEW] ./src/H5FDsec2.c [NEW] ./src/H5FDsec2.h [NEW] Removed/added files for virtual file layer. ./bin/trace ./src/H5.c Removed unused public datatypes and added new VFL public datatypes.

Instead of assuming that the first call to write the boot block is only to allocate space, I've added a function argument which makes this explicit. Changed the way files are compared so that a driver-defined comparison function can be called. Files which belong to different drivers are always considered different. Removed H5F_driver_t since file drivers are now identified by object ID instead of a special non-user-extendible datatype. Removed all the hard-coded low-level file properties which have been replaced by the various file drivers. ./src/H5I.c ./src/H5Iprivate.h Added the H5I_inc_ref() which was removed a few months ago since we finally have a use for it. ./src/H5Ipublic.h Added the H5I_VFL object ID type to identify file drivers in the virtual file layer. ./src/H5MF.c ./src/H5MFprivate.h Moved all the allocation/deallocation code into the virtual file layer which allows file drivers to override much of it. ./src/H5P.c ./src/H5Ppublic.h Moved file driver-specific code into the various file driver files.

The ./test/links program will create a `links.h5' file that demonstrates hard links, soft links, dangling links, and recursive links. A symbolic link is a symbol table entity and doesn't have an object header. It's format is described in H5.format.hml. ./src/H5G.c ./src/H5Gpublic.h ./src/h5ls.c Implemented H5Gstat() and H5Gget_linkval() as documented by Quincey. The `H5G_type_t type' field of `H5G_stat_t' was changed to `int type' because H5G_type_t was already used and the `type' data type should be open-ended. ./src/H5Ffamily.c Removed an incorrect diagnostic message. ./test/big.c Added read/write calls to test partial I/O to big contiguous datasets. With no arguments it writes to a dataset and prints the list of points written which should be redirected to a file. With an argument (the name of a file containing the stdout of a run with no arguments) values are read from the dataset. One would typically say `big >x && big x'.

This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group.

[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.

Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

HGOTO_ERROR (H5E_SYM, H5E_SLINK, FAIL, "too many links");
[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

[svn-r25] ./src/H5AC.c We sort the cache before a complete flush because it might be more efficient to write things back to disk in order of increasing address. If you want the old way then undef the SORT_BY_ADDR constant at the top of H5AC.c I haven't determined which systems and I/O libraries this helps or hurts. (This is currently off because of a bug I need to track down that causes qsort() to run for a really long time). ./src/H5B.c Fixed a couple more bugs. ./src/H5Eprivate.h ./src/H5Eproto.h Added major H5E_DIRECTORY and minor H5E_EXISTS, H5E_COMPLEN. ./src/H5G.c Added directory-aware functions. The heap and B-tree are created when a directory is created instead of when the first symbol is added. This simplifies symbol table entry caching for the directory since the cached value never changes now. ./src/H5Gnode.c ./src/H5Gprivate.h Fine tuned the B-tree K values for symbol tables assuming an average number of symbols is about 100 per directory. The tuning minimizes storage space.

This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group.

[svn-r10978] Purpose: Interim checkin of code changes moving management of the is_dirty flag into the cache code. Description: Prior to this checkin, management of the is_dirty flag was handled above the level of the metadata cache. This can no longer be allowed, as it introduces a race condition in the proposed fix for a cache coherency bug in PHDF5. Solution: Move management fo the is_dirty flag to the cache code proper. Entries are now marked as dirty via a flag on the unprotect call. Platforms tested: h5committested Misc. update:

* John Mainzer - 6/8/05
* Modified function to use the new dirtied parmeter of
* H5AC_unprotect(), which allows management of the is_dirty

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

H5FPclient.c H5FPserver.c - Modified so that if a process requests data that isn't exactly aligned, we can return it if we have the block that contains the requested address. H5G.c H5Gent.c H5Gnode.c H5HL.c H5HLpkg.h H5HLprivate.h H5Oefl.c - Removed the H5HL_peek function since it was doing a (now unsafe) holding of the information in the cache. Replaced with protect and unprotect calls. H5TB.c - Error fix. The TB_dless function wasn't working properly. H5Gstab.c - Format change. H5err.txt H5Edefin.h H5Einit.h H5Epubgen.h H5Eterm.h - Added new error code. Platforms tested: Modi4 (paralle, Fortran) Sol (Fortran) Linux (C++, Fortran) Copper (Parallel, Fortran) Misc. update:

/* Hold the entry's name (& old_name) to restore later */
[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

/* Traverse the link */
[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

HGOTO_ERROR (H5E_SYM, H5E_CANTINIT, FAIL, "unable to create root group");
[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

[svn-r1087] Changes since 19990218 ---------------------- ./src/H5F.c ./src/H5private.h ./src/H5Ipublic.h ./src/H5O.c Fixed a rather nasty bug with file closing that caused the file boot block to be updated incorrectly, effectively truncating the file. The bug I fixed was triggered by: 1. Create a file, F 2. Open an object, X 3. Close file F 4. Reopen file F for read/write. 5. Create and close some objects 6. Close file F 7. Close library (exit). Step 3 pended the close because object X is still open, but the file ID was removed from the H5I_FILE ID group. Step 4 created a new file because it didn't see any matching file on the H5I_FILE ID group. Step 5 extends the file. Step 6 writes the new file boot block to disk. Step 7 closes object X and completes the close from step 3, writing the old boot block information to disk. The new behavior is that step 3 moves the file from the H5I_FILE group to the H5I_FILE_CLOSING group. Step 4 searches both groups and finds the file. Step 5 extends the file using the same H5F_file_t struct as step 3. Step 6 closes the H5F_t struct opened in step 3 but not the H5F_file_t struct shared by steps 1 and 3. Step 7 closes object X which closes the H5F_file_t from step 1, flushing the boot block which was shared by all steps. ./src/H5F.c Added some bulletproofing to file reference counting and removed comments which no longer apply. Added H5F_flush_all() and H5F_close_all() which apply to all files. ./src/H5A.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5I.c ./src/H5Iprivate.h ./src/H5R.c ./src/H5RA.c ./src/H5S.c ./src/H5T.c Added the new H5I_free_t data type to describe the function type to be passed as the `free_func' argument to H5I_init_group(). ./src/H5I.c Bulletproofed the object removal functions. Removed comments which no longer apply. Changed global variable names so they don't violate the naming scheme. Added H5I_debug() that prints the contents of an ID group. Removed H5I_inc_ref() because it isn't used. Reindented a couple of functions. ./src/H5.c ./src/H5G.c ./src/H5Ipublic.h Changed H5I_MAXID to H5I_NGROUPS to better relect the fact that it's the total number of valid ID groups. ./src/H5Shyper.c Changed hyperslab offset arrays to signed quantities to get rid of warnings on DEC cluster. ./src/H5Flow.c ./src/H5Fprivate.h Changed the objno argument of H5F_addr_pack() to be unsigned to get rid of warnings on DEC cluster.

[svn-r329] Changes since 19980324 ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

H5P_genplist_t *gc_plist; /* Property list created */
[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group.

/* create an open group */
[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note.

[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed.

[svn-r876] Changes since 19981102 ---------------------- ./bin/snapshot Made same fix as for the release script yesterday. ./src/H5D.c ./src/H5Dprivate.h ./src/H5G.c ./src/H5Gprivate.h ./src/H5Gpublic.h ./src/H5O.c ./src/H5Oprivate.h ./src/H5RA.c ./src/H5RAprivate.h ./src/H5T.c ./src/H5Tprivate.h Improved object type checking. Instead of determining the object type by trying to open each of the possible types, we keep a table of associations between object type number (like H5G_GROUP, H5G_DATASET, H5D_TYPE, and H5D_RAGGED) and an `isa' function that returns true if the object header has the right messages to make the object a particular type. This mechanism also allows specialization of object types by permitting an object to satisfy more than one `isa' function. Added `isa' functions for groups, datasets, ragged arrays, and committed data types. ./src/H5config.h.in Added HAVE_STAT_ST_BLOCKS. I thought this had already been added, but apparently not. ./tools/h5ls.c Removed system include files since they're already included by H5private.h and since I wasn't including them portably anyway. By default, 1-byte integer types are printed as integer values instead of ASCII characters. However, the `-s' or `--string' command-line switch causes the data to be interpretted as ASCII. String data types are always printed as character data. Ragged arrays are now identified as ragged arrays and h5ls doesn't descend into the group automatically. This uses the new object type specialization stuff. ./tools/h5tools.c ./tools/h5tools.h Added the ability to print 1-byte integer types as either ASCII or numeric data instead of always ASCII. The default is to print as numeric data.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel Misc. update: Updated release_docs/RELEASE

[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.

[svn-r11245] Purpose: Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
2005-08-14 04:53:35 +08:00
[svn-r8731] Purpose: Code cleanup & minor optimization Description: Re-work the way interface initialization routines are specified in the library to avoid the overhead of checking for them in routines where there is no interface initialization routine. This cleans up warnings with gcc 3.4, reduces the library binary size a bit (about 2-3%) and should speedup the library's execution slightly. Platforms tested: FreeBSD 4.10 (sleipnir) w/gcc34 h5committest

FUNC_ENTER_NOAPI_NOINIT(H5G_isa);
[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

[svn-r6411] Purpose: Code cleanup Description: Clean up miscellaneous warnings which have crept into the code. Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD. Adjust gcc compiler flags to be more concise for production mode.

[svn-r299] Changes since 19980224 ---------------------- ./html/Files.html Added a few details for some of the new H5Pset/get functions. ./src/H5F.c ./src/H5Fpublic.h Fixed automatic closing of files on exit(). Added public H5F_ACC_DEBUG. Using it to create or open a file turns on debugging for that file, which currently just prints cache statistics when the file is closed. ./src/H5G.c An error is returned if one tries to set the current working group to something other than a group. ./src/H5Gnode.c Fixed a symbol table bug. Under certain circumstances it was possible to enter a symbol in such a way that lookup of that symbol failed. A bug report was sent to hdf5dev. ./src/H5P.c ./src/H5Ppublic.h Added the H5Pget_...() functions for file drivers. The H5Pget_mpi() is a no-op that always fails.

H5G_t *
[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

if (NULL==(grp->shared = H5FL_CALLOC(H5G_shared_t)))
[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

Added public H5F_ACC_DEBUG. Using it to create or open a file turns on debugging for that file, which currently just prints cache statistics when the file is closed. ./src/H5G.c An error is returned if one tries to set the current working group to something other than a group. ./src/H5Gnode.c Fixed a symbol table bug. Under certain circumstances it was possible to enter a symbol in such a way that lookup of that symbol failed. A bug report was sent to hdf5dev. ./src/H5P.c ./src/H5Ppublic.h Added the H5Pget_...() functions for file drivers. The H5Pget_mpi() is a no-op that always fails.

This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group.

[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

/* Check args */
[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

[svn-r9727] Purpose: Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other.

[svn-r329] Changes since 19980324 ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

[svn-r761] Changes since 19981013 ---------------------- ./src/H5.c Fixed a signed vs. unsigned comparison. ./src/H5D.c Setting a fill value of all zeros will cause the fill value to be written to the dataset instead of relying on the low-level file driver initializing unwritten areas with zero. ./src/H5D.c ./src/H5F.c ./src/H5Fprivate.h ./src/H5G.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5O.c ./src/H5T.c More file mounting stuff. ./src/H5I.c Fixed a bug where trying to close an invalid object id caused a core dump. For instance, H5Gclose(-1). ./MANIFEST ./test/Makefile.in ./test/mount.c [NEW] Mounting tests. ./src/H5R.c Fixed a couple (herr_t)NULL casts.

* Purpose: Return a pointer to the root group of the file. If the file
* is part of a virtual file then the root group of the virtual
* file is returned.
[svn-r150] Changes since 19971219 ---------------------- ./src/H5private.h Changed HDF5_MAJOR_VERSION to 5 ./src/H5Aprivate.h ./src/H5Apublic.h Added group atoms. ./src/H5D.c ./src/H5P.c ./test/istore.c ./test/tohdr.c ./test/tstab.c Updated for symbol table interface changes. ./src/H5F.c ./src/H5Fprivate.h Simpler handling of special case files: empty files and files with a single object. ./src/H5G.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5Gpublic.h ./src/H5Gshad.c (DELETED) ./src/H5Gstab.c ./src/Makefile.in Removed shadows, simplifying code. Symbol table entries are allowed to cache only constant meta data. Fixed naming. ./src/H5O.c ./src/H5Oprivate.h Access to object headers is always done through a symbol table entry instead of a file address. Added stubs for opening and closing object headers to be used when deletion is implemented.

[svn-r178] Changes since 19980127 ---------------------- ./Makefile.in ./config/commence.in With GNU make you can now use `-j' and `-l' options and things get built correctly. I can do a `make -j -l6 test' from a clean hdf5 source tree (after configure) in 45 seconds (8 to build dependencies, 26 to compile everything, and 11 to run the tests). ./src/H5Gnode.c Removed a comment that no longer applies. ./src/H5P.c ./src/H5Pprivate.h ./src/H5Ppublic.h Changed H5Pselect_hyperslab() to H5Pset_hyperslab() and added H5Pget_hyperslab() and H5P_get_hyperslab(). Replaced a couple short memset() calls with a for loop. Removed `if (foo!=NULL)' from around H5MM_xfree() calls. Clear hslab_def when the hyperslab disappears. ./src/H5Tpublic.h Removed trailing enum comma.

[svn-r25] ./src/H5AC.c We sort the cache before a complete flush because it might be more efficient to write things back to disk in order of increasing address. If you want the old way then undef the SORT_BY_ADDR constant at the top of H5AC.c I haven't determined which systems and I/O libraries this helps or hurts.

The heap and B-tree are created when a directory is created instead of when the first symbol is added. This simplifies symbol table entry caching for the directory since the cached value never changes now. ./src/H5Gnode.c ./src/H5Gprivate.h Fine tuned the B-tree K values for symbol tables assuming an average number of symbols is about 100 per directory. The tuning minimizes storage space.

[svn-r329] Changes since 19980324 ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

[svn-r25] ./src/H5AC.c We sort the cache before a complete flush because it might be more efficient to write things back to disk in order of increasing address. If you want the old way then undef the SORT_BY_ADDR constant at the top of H5AC.c I haven't determined which systems and I/O libraries this helps or hurts. (This is currently off because of a bug I need to track down that causes qsort() to run for a really long time). ./src/H5B.c Fixed a couple more bugs. ./src/H5Eprivate.h ./src/H5Eproto.h Added major H5E_DIRECTORY and minor H5E_EXISTS, H5E_COMPLEN. ./src/H5G.c Added directory-aware functions. The heap and B-tree are created when a directory is created instead of when the first symbol is added. This simplifies symbol table entry caching for the directory since the cached value never changes now. ./src/H5Gnode.c ./src/H5Gprivate.h Fine tuned the B-tree K values for symbol tables assuming an average number of symbols is about 100 per directory. The tuning minimizes storage space. Fixed a return value in H5G_node_cmp(). ./src/H5H.c ./src/H5Hprivate.h Moved some macros the the header file. ./src/H5O.c ./src/H5Ocont.c ./src/H5Onull.c ./src/H5Ostab.c Changed the arguments for the decode method for messages. The second argument is the raw message size. Added a class variable for native message size. Added H5O_reset() to free memory used internally by a message. ./src/H5Oname.c NEW ./src/H5Oprivate.h ./src/Makefile The object name message. ./src/hdf5port.h Added defn for HDstrdup()

[svn-r178] Changes since 19980127 ---------------------- ./Makefile.in ./config/commence.in With GNU make you can now use `-j' and `-l' options and things get built correctly. I can do a `make -j -l6 test' from a clean hdf5 source tree (after configure) in 45 seconds (8 to build dependencies, 26 to compile everything, and 11 to run the tests). ./src/H5Gnode.c Removed a comment that no longer applies. ./src/H5P.c ./src/H5Pprivate.h ./src/H5Ppublic.h Changed H5Pselect_hyperslab() to H5Pset_hyperslab() and added H5Pget_hyperslab() and H5P_get_hyperslab(). Replaced a couple short memset() calls with a for loop. Removed `if (foo!=NULL)' from around H5MM_xfree() calls. Clear hslab_def when the hyperslab disappears. ./src/H5Tpublic.h Removed trailing enum comma.

* Function: H5G_insert
[svn-r27] ./src/H5B.c ./src/H5Bprivate.h The B-tree K value comes from a combination of the B-tree subclass and the file. ./src/H5C.c ./src/H5F.c ./src/hdf5lims.h ./src/hdf5type.h Removed the B-tree size parameter and added an array of B-tree K values. Also added symbol table node K value. ./src/H5Eprivate.h ./src/H5Eproto.h Added H5E_LINK for errors involving link counts. ./src/H5G.c Inserting something into a directory with H5G_insert() increments the link count in the object header. The root object should always have a link count of at least 1. ./src/H5Gnode.c ./src/H5Gprivate.h The symbol table node K value comes from the file instead of being a constant. ./src/H5Olink.c Added an assert(), fixed a hard-link bug.

This reduces the number of warnings in other parts of the code but creates a new warning in this file. ./src/H5O.c Plugged a few memory leaks that happen during error handling. ./src/H5Oname.c ./src/debug.c Added `HD' to the beginning of some posix functions.

[svn-r129] Changes since 19970916 ---------------------- ./config/depend.in Fixed backslashes in sed script because the H5Gnode.c dependency info was disappearing. You'll have to rerun config.status to rebuild the Makefiles unless you use gnu make. ./config/conclude.in Also removes emacs backup files, TAGS, and svf backup files. ./config/linux Grouped gcc flags and added provisions for debugging vs. production. ./html/H5.format.html Updated messages 0x0008, 0x0009, and 0x000A. ./html/storage.html Documentation describing storage schemes. ./src/Makefile.in ./test/Makefile.in New source files. ./src/H5A.c ./src/H5Apublic.h ./src/H5C.c Changed VOIDP to void* in a couple places. ./src/H5AC.c ./src/H5ACprivate.h ./src/H5B.c ./src/H5Bprivate.h ./src/H5G.c ./src/H5Gnode.c ./src/H5Gprivate.h ./src/H5H.c ./src/H5O.c Removed `const' from some variables because H5G_node_found() wanted to modify it's udata argument.

Also added an extra argument to the H5AC_find() macro. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c Extra argument passed to the sizeof_rkey() method. ./src/H5Fprivate.c ./src/H5Fistore.c (new) Added indexed I/O operations. ./src/H5G.c ./src/H5Gnode.c ./src/H5Gprivate.h Beginning to add H5G_open/close and related bug fixes. ./src/H5Oprivate.h ./src/H5Oistore.c (new) Added the H5O_ISTORE messsage (0x0008) for indexed storage of objects. ./src/H5private.h Added extra braces around both sides of the FUNC_ENTER() and FUNC_LEAVE() macros so FUNC_ENTER() can appear before declarations or after executable statements the second case is used by H5G_namei() to initialize output arguments to sane values before FUNC_ENTER() might return failure. int f () { int decl1; printf ("This happens before FUNC_ENTER()\n"); FUNC_ENTER (...); int another_declaration; ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c Extra arguments for key encoding and decoding. ./src/H5E.c ./src/H5Epublic.h ./src/H5Fistore.c ./src/H5Oistore.c ./src/H5Oprivate.h Indexed, chunked, sparse storage (not ready for general consumption yet). ./src/H5V.c (new) ./src/H5Vprivate.h (new) ./test/hyperslab.c (new) Vector, array, and hyperslab functions. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Fistore.c ./src/H5Gnode.c ./src/H5V.c ./src/H5Vprivate.h ./test/hyperslab.c Added functionality for indexed storage. ./src/H5F.c Fixed problems with seek optimizing. Recommend we disable it until we can implement it in the file/address class since all of HDF5 must be aware of it. ./src/H5O.c Fixed comeent speling erorr :-) ./MANIFEST Added new files. ./config/conclude.in Added the word `Testing' to the test cases. So if a test program is called hyperslab then the make output will contain the line `Testing hyperslab'. ./config/linux The default file I/O library is Posix section 2 on my linux machine so I can do some I/O performance testing. ./src/H5C.c ./src/H5Cprivate.h ./src/H5Cpublic.h Added ability to set size of indexed-storage B-tree. ./src/H5D.c ./src/H5E.c ./src/H5Epublic.h ./src/H5F.c ./src/H5Fprivate.h ./src/H5G.c ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5Gpublic.h ./src/H5Gshad.c ./src/H5Gstab.c ./test/stab.c Changed `directory' to `group' in numerous places. ./src/H5private.h The FILELIB constant can be set on the compile command-line. ./src/istore.c NEW Tests for indexed storage.

[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

Instead of determining the object type by trying to open each of the possible types, we keep a table of associations between object type number (like H5G_GROUP, H5G_DATASET, H5D_TYPE, and H5D_RAGGED) and an `isa' function that returns true if the object header has the right messages to make the object a particular type. This mechanism also allows specialization of object types by permitting an object to satisfy more than one `isa' function. Added `isa' functions for groups, datasets, ragged arrays, and committed data types. ./src/H5config.h.in Added HAVE_STAT_ST_BLOCKS. I thought this had already been added, but apparently not. ./tools/h5ls.c Removed system include files since they're already included by H5private.h and since I wasn't including them portably anyway. By default, 1-byte integer types are printed as integer values instead of ASCII characters. However, the `-s' or `--string' command-line switch causes the data to be interpretted as ASCII. String data types are always printed as character data. Ragged arrays are now identified as ragged arrays and h5ls doesn't descend into the group automatically. This uses the new object type specialization stuff. ./tools/h5tools.c ./tools/h5tools.h Added the ability to print 1-byte integer types as either ASCII or numeric data instead of always ASCII. The default is to print as numeric data.

Internally, H5G_loc() was modified to return an H5G_entry_t* instead of an H5G_t* so it's more general. Among other things, this allows one to retrieve information about an object like a named type or dataset without knowing the name of the type or dataset: int get_nlinks (hid_t obj) { H5G_stat_t sb; if (H5Gstat(obj, ".", TRUE, &sb)<0) return -1; return sb.nlink; } ./test/gheap.c ./test/istore.c These files needed a couple of changes because they call some of the internal functions whose H5G_t arguments changed to H5G_entry_t. ./src/H5A.c Got rid of all the switch statements for getting symbol table entries for varous objects and replaced them with a call to H5G_loc() allowing attributes to automatically apply to any type of object that belongs to a file. ./test/Makefile.in Moved the ragged array tests from the normal list of tests to the `make timings' target. ./test/ragged.c Added rewrite tests -- rewrite the rows of a dataset changing the number of rows and the length of each row. ./test/mtime.c Added a test that checks that H5Gstat() can be called with a dataset as the first argument. ./src/H5S.c Added #ifdef HAVE_PARALLEL around code to check for the HDF5_MPI_OPT_TYPES environment variable because the global variable that gets set is #ifdef'd. ./bin/release bzip2 uses .bz2 as the file extension.

This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also.

[svn-r329] Changes since 19980324 ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

NEW ./src/H5Ostab.c NEW New functions for dealing with object headers. The H5O.c is the generic stuff, and each particular message has a source file for the specific stuff. Use ./src/H5Ostab.c as a model for implementing other messages. ./src/Makefile ./src/test/Makefile Added new files ./src/debug.c Added debugging calls for object headers. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c ./src/H5MF.c Changed my e-mail address. Improved error handling. ./src/H5Eprivate.h ./src/H5Eproto.h Added more error symbols ./src/H5F.c Changed my e-mail address. Used macros for sizeof offsets and lengths. Added the interface initialization function to H5F_block_read() and H5F_block_write(). Updated H5F_debug() ./src/H5Fprivate.h Got rid of H5F_symbol_table_size(). Use H5G_SIZEOF_ENTRY() instead. Reformatted H5F_decode_offset() for readability. ./src/H5G.c Changed my e-mail address. Improved error handling. Replaced not_implemented_yet__*() with real functions from H5O. ./src/H5Gprivate.h Changed `symtab' to `stab' to be consistent with other stuff. ./src/H5H.c ./src/H5Hprivate.h Changed my e-mail address. Improved error handling. Added an extra argument to H5H_new() to indicate whether you want a global heap or a local heap. ./src/hdf5gen.h Added NELMTS() Fixed FUNC_ENTER() Rewrote FUNC_LEAVE() in terms of HRETURN(). ./src/hdf5meta.h Added `const' to the decode macros. ./src/hdf5pabl.h Added PABLO_SAVE() ./test/testhdf5.c ./test/testhdf5.h Added calls for object header testing. ./test/theap.c Turned off some output.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel Misc. update: Updated release_docs/RELEASE

[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.

[svn-r7917] Purpose: Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)

FUNC_ENTER_NOAPI_NOINIT_NOFUNC(H5G_entof);
[svn-r5467] Purpose: Code cleanup. Description: Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros equivalents in the SAF library and adapted them to our library. I added an additional macro which is equivalent to FUNC_ENTER: FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but none of the library or interface initialization code. This is to be used _only_ for static functions and those which explicitly cannot have the library or interface initialization code enabled (like the API termination routines, etc.). This allowed many more of the functions in the library [but not all yet :-(] to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs. It also reduced the size of the library and executables (by cutting out a bunch of code which was never executed), I'll e-mail the exact results when I've finished editing it.

This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

[svn-r633] Changes since 19980828 ---------------------- ./RELEASE Updated with important changes I made since the second beta. ./src/H5A.c ./src/H5D.c ./src/H5Dprivate.h ./src/H5G.c ./src/H5Gprivate.h ./src/H5R.c ./src/H5Rprivate.h ./src/H5T.c ./src/H5Tprivate.h Any API function that used to take an `hid_t loc_id' followed by a `const char *name' can now take any type of object for the loc_id as long as the object is somehow associated with a file. Internally, H5G_loc() was modified to return an H5G_entry_t* instead of an H5G_t* so it's more general. Among other things, this allows one to retrieve information about an object like a named type or dataset without knowing the name of the type or dataset: int get_nlinks (hid_t obj) { H5G_stat_t sb; if (H5Gstat(obj, ".", TRUE, &sb)<0) return -1; return sb.nlink; } ./test/gheap.c ./test/istore.c These files needed a couple of changes because they call some of the internal functions whose H5G_t arguments changed to H5G_entry_t. ./src/H5A.c Got rid of all the switch statements for getting symbol table entries for varous objects and replaced them with a call to H5G_loc() allowing attributes to automatically apply to any type of object that belongs to a file. ./test/Makefile.in Moved the ragged array tests from the normal list of tests to the `make timings' target. ./test/ragged.c Added rewrite tests -- rewrite the rows of a dataset changing the number of rows and the length of each row. ./test/mtime.c Added a test that checks that H5Gstat() can be called with a dataset as the first argument. ./src/H5S.c Added #ifdef HAVE_PARALLEL around code to check for the HDF5_MPI_OPT_TYPES environment variable because the global variable that gets set is #ifdef'd. ./bin/release bzip2 uses .bz2 as the file extension.

Also, add an "H5F_OBJ_LOCAL" flag for the H5Fget_obj_count() & H5Fget_obj_ids() calls, so that applications can query about objects opened with a particular file ID instead of all the objects opened in the file on disk.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel Misc. update: Updated release_docs/RELEASE

It's format is described in H5.format.hml. ./src/H5G.c ./src/H5Gpublic.h ./src/h5ls.c Implemented H5Gstat() and H5Gget_linkval() as documented by Quincey. The `H5G_type_t type' field of `H5G_stat_t' was changed to `int type' because H5G_type_t was already used and the `type' data type should be open-ended. ./src/H5Ffamily.c Removed an incorrect diagnostic message. ./test/big.c Added read/write calls to test partial I/O to big contiguous datasets. With no arguments it writes to a dataset and prints the list of points written which should be redirected to a file. With an argument (the name of a file containing the stdout of a run with no arguments) values are read from the dataset. One would typically say `big >x && big x'.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes.

Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

By default, 1-byte integer types are printed as integer values instead of ASCII characters. However, the `-s' or `--string' command-line switch causes the data to be interpretted as ASCII. String data types are always printed as character data. Ragged arrays are now identified as ragged arrays and h5ls doesn't descend into the group automatically.

By default, 1-byte integer types are printed as integer values instead of ASCII characters. However, the `-s' or `--string' command-line switch causes the data to be interpretted as ASCII.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

/* Find the object's symbol table entry */
[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

Added H5T_bit_get_d() and H5T_bit_set_d() which treat portions of a bit vector as an unsigned integer. Added H5T_bit_inc() that increments part of a bit vector and returns an indication of overflow. ./src/H5Tconv.c ./src/H5Tpkg.h ./test/dtypes.c Added a slow general floating point conversion which works so far on Intel, MIPS, and DEC but the test is turned off because a cast from double to float will cause a SIGFPE on some systems if an overflow occurs. Added fast hardware conversions between native floating point types. This function is also subject to the SIGFPE problem. ./src/H5detect.c Removed the exponent bias adjustment when the significand isn't normalized. This is now handled in the conversion functions instead. ./src/H5T.c Register new conversion functions.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

[svn-r5096] Purpose: Bug Fix Description: The H5Gget_objinfo() function was not setting the 'fileno' field in the H5G_stat_t struct passed in. Solution: Added a "file serial number" to each file currently open in the library and put that in the 'fileno' field. If a file is opened twice (with H5Fopen) and the VFL driver detects that it is the same file (i.e. the two file structures have the same "shared file info" in the library's memory structures), they will have the same serial number. This serial number has two drawbacks: - If a VFL driver doesn't/can't detect that two calls to H5Fopen with the same file actually _are_ the same file, each will get a different serial number - If the same file is closed and re-opened, the serial number will be different. It is be possible to fix the second drawback for many VFL drivers, but it would be a lot of effort and probably isn't worth it until we've got a good reason to do it. Dunno if we'll ever be able to fix the first drawback... Platforms tested: FreeBSD 4.5 (sleipnir) VS: ----------------------------------------------------------------------

if(H5F_get_fileno(obj_ent.file,&statbuf->fileno)<0)
[svn-r5842] Purpose: Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.

[svn-r346] Changes since 19980410 ---------------------- ./html/H5.format.html ./src/H5E.c ./src/H5Epublic.h ./src/H5F.c ./src/H5G.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5Gprivate.h ./src/h5ls.c ./test/Makefile.in Symbolic links are now supported. The ./test/links program will create a `links.h5' file that demonstrates hard links, soft links, dangling links, and recursive links. A symbolic link is a symbol table entity and doesn't have an object header. It's format is described in H5.format.hml. ./src/H5G.c ./src/H5Gpublic.h ./src/h5ls.c Implemented H5Gstat() and H5Gget_linkval() as documented by Quincey. The `H5G_type_t type' field of `H5G_stat_t' was changed to `int type' because H5G_type_t was already used and the `type' data type should be open-ended. ./src/H5Ffamily.c Removed an incorrect diagnostic message. ./test/big.c Added read/write calls to test partial I/O to big contiguous datasets. With no arguments it writes to a dataset and prints the list of points written which should be redirected to a file. With an argument (the name of a file containing the stdout of a run with no arguments) values are read from the dataset. One would typically say `big >x && big x'.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

The ./test/links program will create a `links.h5' file that demonstrates hard links, soft links, dangling links, and recursive links. A symbolic link is a symbol table entity and doesn't have an object header. It's format is described in H5.format.hml. ./src/H5G.c ./src/H5Gpublic.h ./src/h5ls.c Implemented H5Gstat() and H5Gget_linkval() as documented by Quincey. The `H5G_type_t type' field of `H5G_stat_t' was changed to `int type' because H5G_type_t was already used and the `type' data type should be open-ended. ./src/H5Ffamily.c Removed an incorrect diagnostic message. ./test/big.c Added read/write calls to test partial I/O to big contiguous datasets. With no arguments it writes to a dataset and prints the list of points written which should be redirected to a file. With an argument (the name of a file containing the stdout of a run with no arguments) values are read from the dataset. One would typically say `big >x && big x'.

[svn-r876] Changes since 19981102 ---------------------- ./bin/snapshot Made same fix as for the release script yesterday. ./src/H5D.c ./src/H5Dprivate.h ./src/H5G.c ./src/H5Gprivate.h ./src/H5Gpublic.h ./src/H5O.c ./src/H5Oprivate.h ./src/H5RA.c ./src/H5RAprivate.h ./src/H5T.c ./src/H5Tprivate.h Improved object type checking. Instead of determining the object type by trying to open each of the possible types, we keep a table of associations between object type number (like H5G_GROUP, H5G_DATASET, H5D_TYPE, and H5D_RAGGED) and an `isa' function that returns true if the object header has the right messages to make the object a particular type. This mechanism also allows specialization of object types by permitting an object to satisfy more than one `isa' function. Added `isa' functions for groups, datasets, ragged arrays, and committed data types. ./src/H5config.h.in Added HAVE_STAT_ST_BLOCKS. I thought this had already been added, but apparently not. ./tools/h5ls.c Removed system include files since they're already included by H5private.h and since I wasn't including them portably anyway. By default, 1-byte integer types are printed as integer values instead of ASCII characters. However, the `-s' or `--string' command-line switch causes the data to be interpretted as ASCII. String data types are always printed as character data. Ragged arrays are now identified as ragged arrays and h5ls doesn't descend into the group automatically. This uses the new object type specialization stuff. ./tools/h5tools.c ./tools/h5tools.h Added the ability to print 1-byte integer types as either ASCII or numeric data instead of always ASCII. The default is to print as numeric data.

[svn-r10978] Purpose: Interim checkin of code changes moving management of the is_dirty flag into the cache code. Description: Prior to this checkin, management of the is_dirty flag was handled above the level of the metadata cache. This can no longer be allowed, as it introduces a race condition in the proposed fix for a cache coherency bug in PHDF5. Solution: Move management fo the is_dirty flag to the cache code proper. Entries are now marked as dirty via a flag on the unprotect call. Platforms tested: h5committested Misc. update:

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

/*
* Get the symbol table entry for the link head and the symbol table
* entry for the group in which the link head appears.
*/
[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

The ./test/links program will create a `links.h5' file that demonstrates hard links, soft links, dangling links, and recursive links. A symbolic link is a symbol table entity and doesn't have an object header. It's format is described in H5.format.hml. ./src/H5G.c ./src/H5Gpublic.h ./src/h5ls.c Implemented H5Gstat() and H5Gget_linkval() as documented by Quincey. The `H5G_type_t type' field of `H5G_stat_t' was changed to `int type' because H5G_type_t was already used and the `type' data type should be open-ended. ./src/H5Ffamily.c Removed an incorrect diagnostic message. ./test/big.c Added read/write calls to test partial I/O to big contiguous datasets. With no arguments it writes to a dataset and prints the list of points written which should be redirected to a file. With an argument (the name of a file containing the stdout of a run with no arguments) values are read from the dataset. One would typically say `big >x && big x'.

if (H5HL_unprotect(grp_ent.file, dxpl_id, heap, stab_mesg.heap_addr, H5AC__NO_FLAGS_SET) < 0)
[svn-r7489] Purpose: Update Description: A lot of modifications for the FPHDF5 stuff: H5AC.c H5ACprivate.h - Removed AC_find (it's replaced with AC_protect and AC_unprotect). Added flushing if it's an FPHDF5 driver and we're doing an AC_set or AC_unprotect with the dirty flag set. H5B.c - Split up the B_flush function into different functions since the one function was doing serialization which is better left as a separate entity. H5D.c - Removed some FPHDF5 code that was incorrect H5F.c - Split up the F_flush function so that it no longer allocates file space. Created new functions (F_init_superblock, F_read_superblock, and F_write_superblock) for greater modularity and so that the FPHDF5 non-captain processes can read the superblock after the captain process writes it. H5FD.c - Error message correction. H5FDfphdf5.c - Removed MPI barrier call that wasn't needed. H5FPclient.c H5FPserver.c - Modified so that if a process requests data that isn't exactly aligned, we can return it if we have the block that contains the requested address. H5G.c H5Gent.c H5Gnode.c H5HL.c H5HLpkg.h H5HLprivate.h H5Oefl.c - Removed the H5HL_peek function since it was doing a (now unsafe) holding of the information in the cache. Replaced with protect and unprotect calls. H5TB.c - Error fix. The TB_dless function wasn't working properly. H5Gstab.c - Format change. H5err.txt H5Edefin.h H5Einit.h H5Epubgen.h H5Eterm.h - Added new error code. Platforms tested: Modi4 (paralle, Fortran) Sol (Fortran) Linux (C++, Fortran) Copper (Parallel, Fortran) Misc. update:

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

It's not done yet, but I needed it for debugging the contents of files from Jim Reus. ./tools/h5ls.c Added the `-d' and `--dump' options which cause the contents of a dataset to be printed. Added `-w N' and `--width=N' options to control how wide the raw data output should be. If you want single-column output then say `-w1'. Printing dataset values can now handle datasets of any integer or floating point atomic type. As a special case, integers which are one byte wide are treated a character strings for now. Sample output: $ h5ls --dump --width=60 banana.hdf ARCHIVE 0:0:0:744 Dataset {52/Inf} Data: (0) "U struct complex { double R; double I; };\012V" (43) " double;\012" U 0:0:0:2500 Dataset {256/512} Data: printing of compound data types is not implemented yet V 0:0:0:3928 Dataset {256/512} Data: (0) 0, 0.015625, 0.03125, 0.046875, 0.0625, (5) 0.078125, 0.09375, 0.109375, 0.125, 0.140625, (10) 0.15625, 0.171875, 0.1875, 0.203125, 0.21875, (15) 0.234375, 0.25, 0.265625, 0.28125, 0.296875, ...

Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes.

[svn-r5471] Purpose: Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note.

[svn-r6387] Purpose: Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

[svn-r9329] Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

[svn-r9727] Purpose: Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes".

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.
