[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-r5839] Purpose: Code cleanup Description: Move operations on each type of selection into the source code file for each selection type (all->H5Sall.c, hyperslab->H5Shyper.c, etc.) Remove central H5S_select_<foo> operations, instead calling the operations through function pointers in each selection (a much more object-oriented approach). Platforms tested: FreeBSD 4.6 (sleipnir)

[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-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-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)

It's a one line change. Changed the way the library is closed so we have more control over the order the interfaces are shut down. 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.

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.

Now it handles cycles between packages and isn't so sensitive to dependencies between packages. A package might shut down only to be restarted to process a request from some other package being shut down. Loops are detected after 100 iteractions and the shutdown is aborted with a message on standard error. This also makes it a lot easier to debug. ./src/H5A.c Fixed H5A_write() and H5A_read() so they pass a non-null background buffer to the conversion functions. This is necessary when an attribute has a compound data type. ./src/H5Flow.c ./src/H5Fprivate.h ./src/H5Fsec2.c Reindented new Win32 stuff. ./src/H5Odtype.c Fixed a bug when enumeration types are used in a compound data type. The byte pointer wasn't incremented after the type information was written. ./tools/h5ls.c Compound data types display their total size because it's not always obvious from looking at the members. Scalar attributes show their space as `scalar' instead of `{}'. The index value is not printed for attributes that have only a few values. Instead the word `Data:' is printed on the first line of attribute data. Named types display their data type only if verbose output was requested.

A package might shut down only to be restarted to process a request from some other package being shut down. Loops are detected after 100 iteractions and the shutdown is aborted with a message on standard error. This also makes it a lot easier to debug. ./src/H5A.c Fixed H5A_write() and H5A_read() so they pass a non-null background buffer to the conversion functions. This is necessary when an attribute has a compound data type. ./src/H5Flow.c ./src/H5Fprivate.h ./src/H5Fsec2.c Reindented new Win32 stuff. ./src/H5Odtype.c Fixed a bug when enumeration types are used in a compound data type. The byte pointer wasn't incremented after the type information was written. ./tools/h5ls.c Compound data types display their total size because it's not always obvious from looking at the members. Scalar attributes show their space as `scalar' instead of `{}'. The index value is not printed for attributes that have only a few values. Instead the word `Data:' is printed on the first line of attribute data. Named types display their data type only if verbose output was requested.

[svn-r1224] Changes since 19990426 ---------------------- ./tools/h5tools.c ./tools/h5tools.h Finally fixed a long-standing bug that caused core dumps if a compound datum rendered to more than some number of characters (we kept bumping up the limit at the risk of violating stack size limits on some machines). The fix works only on systems that have the vsnprintf() function (otherwise a 4kB limit is imposed, which if violated probably dumps core). If vsnprintf() is present then the library dynamically allocates space for the output string. Also made it possible to control how compound data is rendered across multiple lines of output by allowing the caller to specify where optional line-breaks get inserted. The output functions split up the value at one or more optional line-breaks to prevent it from wrapping around the screen. If a datum doesn't fit on the current line but would fit on the next line then it is printed on the next line regardless of whether optional line-breaks would have prevent wrapping around the screen. This makes it easier to find the beginnings of compound data values. This feature is disabled by default but can be enabled by the application. If a datum doesn't fit on the current line and the previous datum also occupied more than one line then we move to the next line before printing. This makes it easier to find the beginnings of compound data values but prevents the output from looking fragmented if there are only a few long values among mostly short values. This feature is disabled by default but can be enabled by the application. The application can control the printf() formats used for all the native data types. The defaults are what the library used to use: %g, %ld, %lu, %d, and %u ./tools/h5ls.c Compound datatype values can now be split across multiple lines of output instead of just wrapping. Also, when lots of compound values are too long they all start at the beginning of a line. This only required about 10 lines of changes in the setup for tools library calls (I didn't modify the h5dump program because it uses its own version of the tools library that forked off long ago). Added code for Win32 which is unable to cast `unsigned long long' to `double'. If the dataset size exceeds (2^63)-1 then the percent utilization is not displayed (this is easily possible with chunked datasets). This is untested yet. ./configure.in ./src/H5config.h.in ./src/H5.c ./src/H5private.h Check for vsnprintf() and provide a simple, stupid definition if it isn't available. The stupid definition just calls vsprintf() and ignores the second argument. This can result in buffer overflows in h5ls and h5dump since vsprintf() is an unsafe function (and anyone can create an hdf5 file that runs an arbitrary command from h5ls and h5dump in that case)! ./config/conclude.in Remove more *.o files for `make clean' ./src/H5A.c ./src/H5D.c ./src/H5F.c ./src/H5I.c ./src/H5Iprivate.h ./src/H5P.c ./src/H5R.c ./src/H5RA.c ./src/H5S.c ./src/H5T.c ./src/H5TB.c Cleaned up a memory leak during H5_term_library() by allowing H5I_clear_group() to skip items that couldn't be freed. This allows the item to remain in the group until we can free it later. ./src/H5F.c The H5F_close_all() function fails if a file cannot be closed.

It's a one line change. Changed the way the library is closed so we have more control over the order the interfaces are shut down. 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.

[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-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)

The `long long' names will be changed shortly to make them portable to Win32. Changed H5T_init() to H5T_native_open() and added an H5T_native_close() to open and close the predefined native data types. Increased the initial size of the type conversion table from 64 to 128 entries. Reordered the 90 new integer conversion functions so the names that are printed favor `int' over `short' or `long' when two of them are the same. ./test/dtypes.c Added hardware and software integer conversion tests for the 56 functions I added recently but not the additional 36 checked in this time. That will come next. Call H5close() after each test so type conversion statistics are easier to follow. Try this: $ HDF5_DEBUG=t ./dtypes Added more debugging output for when things go wrong. ./src/H5private.h Removed trailing carriage-returns inserted by broken operating system ;-)

The `long long' names will be changed shortly to make them portable to Win32. Changed H5T_init() to H5T_native_open() and added an H5T_native_close() to open and close the predefined native data types. Increased the initial size of the type conversion table from 64 to 128 entries. Reordered the 90 new integer conversion functions so the names that are printed favor `int' over `short' or `long' when two of them are the same. ./test/dtypes.c Added hardware and software integer conversion tests for the 56 functions I added recently but not the additional 36 checked in this time. That will come next. Call H5close() after each test so type conversion statistics are easier to follow. Try this: $ HDF5_DEBUG=t ./dtypes Added more debugging output for when things go wrong. ./src/H5private.h Removed trailing carriage-returns inserted by broken operating system ;-)

uint8_t *p; /* Pointer to OID to store */
uint8_t *buf; /* Buffer to store serialized selection in */
[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-r1572] Changes since 19990810 ---------------------- ./MANIFEST ./src/H5FDmulti.c [NEW] ./src/H5FDmulti.h [NEW] ./src/Makefile.in ./src/hdf5.h The split driver was reimplemented as a more general "multi" driver which is capable of splitting data into multiple files like the family driver except the partioning is done by memory usage type instead of address. The H5Pset_fapl_split() function just calls H5Pset_fapl_multi() with arguments which prepare to split the address space into two files: meta and raw data. This is the first version. I plan to allow the open() call to relax a bit which would allow one to open an hdf5 file when only the meta-data file is present. This would allow a very large file to be split and stored on tape and the relatively small meta file to be mirrored on disk to allow limited browsing of the file (any request for raw data would fail). ./src/H5private.h ./src/H5F.c ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c Added the ability for a file driver to store information in the superblock which would be needed if the file were opened again later for reading. The format is driver-defined which allows users to extend it however they like. ./doc/html/H5.format.html Added information about the new driver information block of the superblock. This is where file drivers store information they need in order to reopen the file later. ./src/H5F.c ./src/H5Fprivate.h ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c ./src/H5Fistore.c ./src/H5R.c The file access properties and the file access property list were decoupled, which allows the property list to more cleanly contain properties for various levels of the file and which allows the property list to be modified more cleanly when opening files. ./src/H5.c ./src/H5FDpublic.h Removed H5FD_MEM_META and H5FD_MEM_GROUP since they're never used. ./src/H5D.c Changed the way we detect the MPIO driver in all these special cases. ./src/H5F.c ./src/H5Rpublic.h ./test/tfile.c The default file sizeof(offset) was changed to be a function of haddr_t instead of hsize_t. THE H5RPUBLIC.H DEFINITIONS WILL HAVE PROBLEMS IF THE USER CREATES A FILE WITH NON-DEFAULT OFFSET AND SIZE SIZES! ./src/H5F.c Fixed an uninitialized memory access bug in file closing related to the VFL. ./src/H5T.c ./src/H5Tpublic.h Added an H5T_NATIVE_HADDR predefined datatype which corresponds to the `haddr_t' type. ./test/Makefile.in Reformatted long lines. ./test/big.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Removed the H5F_ACC_DEBUG flag from file creation/open calls. ./test/big.c Plugged a memory leak. ./test/h5test.c Added support for the `multi' driver. Removed #warning about not having the stdio driver. Plans are to not implement it since the sec2 driver serves the same purpose and testing didn't show any difference in execution times between the two.

H5_CHECK_OVERFLOW(buf_size,hssize_t,size_t);
[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-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 `long long' names will be changed shortly to make them portable to Win32. Changed H5T_init() to H5T_native_open() and added an H5T_native_close() to open and close the predefined native data types. Increased the initial size of the type conversion table from 64 to 128 entries. Reordered the 90 new integer conversion functions so the names that are printed favor `int' over `short' or `long' when two of them are the same. ./test/dtypes.c Added hardware and software integer conversion tests for the 56 functions I added recently but not the additional 36 checked in this time. That will come next. Call H5close() after each test so type conversion statistics are easier to follow. Try this: $ HDF5_DEBUG=t ./dtypes Added more debugging output for when things go wrong. ./src/H5private.h Removed trailing carriage-returns inserted by broken operating system ;-)

uint8_t *p; /* Pointer to OID to store */
[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)

This change should be folded into the documentation for these three functions for the release.

case H5G_DATASET:
[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.

[svn-r1385] Updated H5Rdereference, H5Rget_object_type and H5Rget_region to accept a location ID (i.e. a file or group ID) as well as the dataset ID.

[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-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.

[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-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.

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).

[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.

[svn-r1151] Changes since 19990318 ---------------------- ./Makefile.in ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] ./config/commence.in ./config/conclude.in ./config/dec-osf4.x ./config/depend.in ./config/freebsd ./config/linux-gnu ./config/linux-gnulibc1 ./config/linux-gnulibc2 ./config/solaris2.x ./examples/Makefile.in ./src/Makefile.in ./test/Makefile.in ./testpar/Makefile.in ./tools/Makefile.in ./tools/testh5dump.sh Changes that allow hdf5 to be configured and compiled in a directory other than the source directory. This is especially useful if you want to concurrently compile with different compilers and/or compile flags, or if the hdf5 source is on read-only media like a CDROM. The changes were surprisingly easy ;-) Here's what you can do now... $ mkdir /tmp/build1 # or something $ cd /tmp/build1 $ /cdrom/hdf5/configure # where ever the source is $ make Paul, you'll have to change the testh5toh4 script similar to the way I changed testh5dump.sh. I started working on it but then gave up because of a number of problems: (1) I had to comment out all the tests that let h5toh4 choose the output file name because it always tried to put the output file in the same directory as the input file, (2) if path names are used during the h4 dump then they interfere with the diff. The test works fine when run in the source directory, but try this instead: $ gunzip <hdf5-1.1.67.tar.gz |tar xf - $ chmod -R ugo-w hdf5-1.1.67 $ mkdir build $ cd build $ ../hdf5-1.1.67/configure $ make check Dan, I didn't modify the pablo/Makefile.in because I have no way to test it. I think all you need to do is add a couple lines before the @COMMENCE@ line and add a couple search directories for header files. Anyway, it seems like almost an exact duplicate of the src/Makefile.in, so it shouldn't be a problem... ./Makefile.in Removes a few more temporary files during make clean and distclean. ./configure.in I fixed the creation of the time-stamp files so that the initial make doesn't have to regenerated all the makefiles (only GNU make users will see any change). ./src/H5R.c Changed a return type from `intn' to `int' for an API function. ./src/H5detect.c Added the volatile qualifier to a couple more variables. ./tools/h5tools.c Fixed a compiler warning about an unused local. ./tools/h5toh4.c Initialized `optind' to 1 because it's zero on my system. It should always be one on a unix system. ./tools/testh5toh4 Redirected "broken pipe" messages to /dev/null so outut is formatted correctly.

[svn-r1385] Updated H5Rdereference, H5Rget_object_type and H5Rget_region to accept a location ID (i.e. a file or group ID) as well as the dataset ID. This should allow Dave to get the palettes stored in the file correctly and also enable Bob and/or Bruce's indexing stuff. This change should be folded into the documentation for these three functions for the release. Also, I fixed a number of bugs in the hyperslab and point selection iterators for H5Diterate and they are working correctly now.

H5G_entry_t *loc = NULL; /* Symbol table entry */
H5F_t *file=NULL; /* File object */
[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.

[svn-r1306] Changes since 19990602 ---------------------- ./doc/html/Datatypes.html ./test/dtypes.c Added documentation and tests for opaque types. ./tools/h5ls.c Added a `-x' or `--hexdump' argument which is not fully implemented (because I want to synchronize h5tools.c first) but which will eventually print raw data in hexadecimal format without any translation from disk. This would be useful for debugging references and VL types. ./tools/h5tools.c Added support for references (not quite finished yet, but compiles -- I wanted to sync up this file before Patrick and I got too far apart...) ./src/H5R.c Checked for error return value from H5R_get_object_type() ./src/H5A.c ./src/H5D.c Changed error return values from NULL to FAIL ./test/Makefile.in ./test/trefer.c Creates trefer1.h5 and trefer2.h5 so that the second test doesn't clobber the first file since the files might be useful for debugging.

[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-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 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-r4747] Purpose: Bug Fix. Description: The H5Rget_object_type function could not get the object type for dataset region references. Solution: Added a new function, H5Rget_obj_type, to replace H5Rget_object_type. The new function requires the reference type as an additional parameter, in order to allow queries on different reference types to be performed correctly. Platforms tested: FreeBSD 4.4. (sleipnir)

[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.
