* [svn-r6632] Purpose:Quincey Koziol2003-04-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix Description: This fixes a bug in the low-level metadata caching code in the library which could possibly lose metadata during file I/O when a lot of objects are inserted into a group. This also fixes a couple of (similar) fencepost bugs in the B-tree deletion code. Solution: For the metadata bug - call the low-level driver's 'write' routine instead of H5FD_write. For the B-tree bug - include the correct number of keys. Platforms tested: FreeBSD 4.8 (sleipnir) w/C++ Linux 2.4 (burrwhite) w/FORTRAN Solaris 2.7 (arabica) w/FORTRAN IRIX64 6.5 (modi4) w/FORTRAN & parallel (h5committest is still not working for me on burrwhite) Misc. update:

* [svn-r6464] Elena Pourmal2003-03-051-0/+7
| | | | | | | | | | | | | | | | | | Purpose: Maintenance Description: * Added support for generic properties. * Added support for time allocation properties. * Added support for variable length datatypes (only datatypes based on INTEGER, REAL and CHARACTER Fortran types are supported). * added some missing functions Solution: I am checking in new Fortran APIs and their man pages to support 1.5 features listed above. Not all APIs have tests yet. APIs were written in Fall 2002, and I am afraid that I will loose the code or totally forget what I did if I wait longer. ;-) Platforms tested: arabica (fortran), eirene (fortran), modi4 (parallel, fortran)

* [svn-r6387] Purpose:Quincey Koziol2003-02-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r6383] Purpose:Quincey Koziol2003-02-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature for developers. Description: Added "function stack" tracing to library. This allows developers (there is no public API) to call H5FS_print within the library and get a listing of the functions traversed to reach that point in the library. Eventually, I may add support for reporting the parameters to each function also... Mainly for debugging parallel I/O programs, but I think it will come in handy in other cases also. The function stack tracking is controlled with a configure switch: --enable-funcstack, which defaults to enabled currently. When we branch for 1.6, we should change the default setting on the branch to be disabled. Also, added a destructor to the thread-specific keys when thread-safety is turned on in the library. Otherwise, they were leaking memory and causing difficult to debug errors in threaded programs (like the test/ttsafe test). Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) w/thread-safety enabled. Misc. update: Updated MANIFEST with new files added (src/H5FS.c & src/H5FDprivate.h) Update release_docs/RELEASE with thread-safety bug fix.

* [svn-r6330] Purpose:Quincey Koziol2003-01-241-0/+2
| | | | | | | | | | | | | | | Bug Fix Description: When calling H5Fopen with the core VFL driver, but without the H5F_ACC_CREAT flag goes ahead and creates a memory file. Solution: Check for the H5F_ACC_CREAT flag before allowing the memory file to be created. Platforms tested: FreeBSD 4.7 (sleipnir)

* [svn-r6307] Purpose:Quincey Koziol2003-01-211-0/+2
| | | | | | | | | | | | | | | | | Bug fix Description: Currently, when the library encounters an object header message that isn't know, it fails to open that object in the file. Solution: Allow the library to skip over the unknown object header message and continue to process the remaining messages, in the hope that the skipped message isn't important later. If it is important, it will be caught at a higher level of the library. Platforms tested: FreeBSD 4.7 (sleipnir)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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?
