* Created: H5G.c
* Jul 18 1997
* 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
* the H5Gnode.c file.
*
* 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 |
* +--------------+------------+--------------------------------+
* | File ID | "/foo/bar" | Find `foo' within `bar' within |
* | | | the root group of the specified|
* | | | file. |
* +--------------+------------+--------------------------------+
* | File ID | "foo/bar" | Find `foo' within `bar' within |
* | | | the root group of the specified|
* | | | file. |
* +--------------+------------+--------------------------------+
* | File ID | "/" | The root group of the specified|
* | | | file. |
* +--------------+------------+--------------------------------+
* | File ID | "." | The root group of the specified|
* | | | the specified file. |
* +--------------+------------+--------------------------------+
* | Group ID | "/foo/bar" | Find `foo' within `bar' within |
* | | | the root group of the file |
* | | | containing the specified group.|
* +--------------+------------+--------------------------------+
* | Group ID | "foo/bar" | File `foo' within `bar' within |
* | | | the specified group. |
* +--------------+------------+--------------------------------+
* | Group ID | "/" | The root group of the file |
* | | | containing the specified group.|
* +--------------+------------+--------------------------------+
* | Group ID | "." | The specified 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? FreeBSD 4.7 (sleipnir) serial & parallel Solaris 2.6 (baldric) serial

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. 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.

[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.

/*-------------------------------------------------------------------------
* Function: H5G_visit
*
* Purpose: Recursively visit all the links in a group and all
* the groups that are linked to from that group. Links within
* each group are visited according to the order within the
* specified index (unless the specified index does not exist for
* a particular group, then the "name" index is used).
*
* NOTE: Each _link_ reachable from the initial group will only be
* visited once. However, because an object may be reached from
* more than one link, the visitation may call the application's
* callback with more than one link that points to a particular
* _object_.
*
* Return: Success: The return value of the first operator that
* returns non-zero, or zero if all members were
* processed with no operator returning non-zero.
*
* Failure: Negative if something goes wrong within the
* library, or the negative value returned by one
* of the operators.
*
