* [svn-r7426] Purpose:Quincey Koziol2003-08-281-15/+10
| | | | | | | | | | | | | | | | | Bug fix Description: When datasets are deleted from a file, they are removed from the sieve buffer, but instead of invalidating only the part of the sieve buffer affected, the sieve buffer code would throw away the entire sieve buffer, potentially including other raw data in the buffer that hadn't been written to disk yet. Solution: Improve the sieve buffer clearing code to handle partial invalidations. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7362] Purpose:Quincey Koziol2003-08-141-1/+1
| | | | | | | | | | | | | Bug fix Description: Allow a user block to be "inserted" in front of a file (probably by writing a validly-sized userblock to a new file and then appending another HDF5 file to the new file). Platforms tested: FreeBSD 4.8 (sleipnir) h5committested
* [svn-r7243] Purpose:Quincey Koziol2003-07-211-0/+1
| | | | | | | | | | | | Bug fix Description: Fix bug with combination of fill-values, chunked datasets and variable-length strings. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest

* [svn-r6870] Purpose:Quincey Koziol2003-05-131-3/+6
| | | | | | | | | | | | New test Description: Added test to check for dangling objects being handled correctly by the library. Platforms tested: FreeBSD 4.8 (sleipnir) h5committested
* [svn-r6525] Purpose:Albert Cheng2003-03-271-0/+2
| | | | | | | | | | | | | | | | New test feature Description: Added the VFD_LIST definition to support the "make check-vfd" tests. Platforms tested: h5committested. Since check-vfd is not invoked by default, I went to each machine to invoke them by hand. The target worked fine but there were errors reported from those driver tests. (Those errors were beyond the scope of this make target test.) Misc. update:
* [svn-r6436] Purpose:Quincey Koziol2003-02-241-11/+19
| | | | | | | | | | | | | New internal feature Description: Add internal API for building and working with heaps (H5HP). This will be used for the LRU algorithm in the new metadata cache code. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir)
* [svn-r6330] Purpose:Quincey Koziol2003-01-241-2/+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-r6252] Purpose:Quincey Koziol2003-01-091-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | Purpose: Added 'ID to name' support Description: There is a new API function H5Iget_name Most of the changes are on H5G.c , regarding the symbol table entry struct H5G_entry_t which has 2 new fields 'name' and 'old_name' A new private function was introduced H5G_ent_copy, that does a deep copy between 2 symbol table entries The test file is getname.c Platforms tested: windows 2000, Linux, Solaris
* [svn-r5895] Purpose:Quincey Koziol2002-08-271-6/+6
| | | | | | | | | | | | Code cleanup/More tests Description: Cleaned up some compiler warnings and wrote additional tests for space allocation and storage size routines. Platforms tested: FreeBSD 4.6 (sleipnir) w/serial & parallel. Will be testing on IRIX64 6.5 (modi4) in serial & parallel shortly.
* [svn-r5875] Purpose:Quincey Koziol2002-08-141-2/+2
| | | | | | | | | | | | | | Additional regression tests & bug fixes Description: There was no testing for the H5Dget_storage_size function and it seemed to be having problems with compressed, chunked datasets, so write some tests to verify that its working correctly. Also, fix case for allocating storage early for chunked datasets Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel
* [svn-r5586] Purpose:Quincey Koziol2002-06-111-1/+1
| | | | | | | | | | | | | | | | Bug Fix Description: H5Dcreate and H5Tcommit allow "empty" compound and enumerated types (i.e. ones with no members) to be stored in the file, but this causes an assertion failure and is somewhat vapid. Solution: Check the datatype "makes sense" before using it for H5Dcreate and H5Tcommit. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5502] Purpose:Quincey Koziol2002-06-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Test Bug Fix Description: Under certain [obscure] circumstances, an object header would get paged out of the metadata cache, and when it was accessed again and brought back into the cache, and immediately had additional metadata added to it (an attribute, usually, or perhaps adding an object to a group), and needed to be extended with a continuation message, but there was no room in any existing object header chunks for the continuation message and an existing object header message needed to be moved to the new object header chunk (I told you it was obscure :-), the object header message moved to the new chunk (not the new metadata being added) would get corrupted. *whew* :-) Solution: Actually copy the "raw" object header message information of the object header message being moved to the new chunk, instead of relying on the "native" object header message information being re-encoded when the object header is flushed. This is because when an object header is paged out of the metadata cache and subsequently brought back in, the "native" information pointer in memory is reset to NULL and only the "raw" information exists. [Actually, this additional testing doesn't trigger the bug, which needs _lots_ of objects to be created and accessed, but it does execise the object header continuation code more than other tests in the library.] Platforms tested: Solaris 2.7 (arabica) & FreeBSD 4.5 (sleipnir)
* [svn-r5257] Purpose:Albert Cheng2002-04-251-2/+0
| | | | | | | | | | | | | | | | | | | Bug fix Description: $(LT_RUN) was used to execute ./H5detect in src/Makefile.in. $RUNTEST was set to $(LT_RUN) which was used to execute sequential executable. $(LT_RUN) is "../libtool --mode=execute". But libtool invokes some commands that are not supported in the Tflops machine. That caused failures during the build and check processes. Solution: Upon investigation, there does not seem to be need to use $(LT_RUN) any more. The "libtool --mode=link" now generates a "fake" executable that is actually a command-script file that can regenerate the real executable with dynamic libraries hooks setup properly. Undo all those $LT_RUN substitute and let $RUNSERIAL execute those sequential executables. Platforms tested: Eirene(serial), modi4(parallel)
* [svn-r5191] Purpose:Quincey Koziol2002-04-171-1/+1
| | | | | | | | | | | | | | | | | | | Bug fix Description: When several level deep nested compound & VL datatypes are used, the data in the nested compound datatypes is incorrectly sharing the same "background buffer", causing data corruption when the data is written to the file. Solution: Allocate a separate background buffer for each level of the nested types to convert. (Also allocate temporary background buffers for array datatypes, where this sort of problem could occur also) Added more regression tests to check for these errors. Platforms tested: FreeBSD 4.5 (sleipnir) & Solaris 2.6 (baldric)

* [svn-r5097] Purpose:Quincey Koziol2002-03-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: Regression test for following bug: 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: ----------------------------------------------------------------------
* [svn-r4943] Purpose:Bill Wendling2002-02-121-23/+23
| | | | | | | | | Cleanup Description: Added set_extend.h5 file to the CLEANUP macro in the Makefile so that it'll be removed when the other temp files are removed. Platforms tested: Linux

* [svn-r4851] Purpose:Quincey Koziol2002-01-231-4/+4
| | | | | | | | | | | | | | | | | | Bug Fix Description: When file space was returned to the file space free-list for reuse, occasionally raw data allocations which used space from the free-list would overlap with the metadata accumulator and get over-written with the cached information in the accumulator, corrupting the data. Solution: Check if the space about to be recycled on the free-list is going to be used for raw data and also overlaps with the metadata accumulator cache, avoiding using space that fits those criteria. This fixes bug #701 Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4757] Purpose:Albert Cheng2001-12-301-10/+4
| | | | | | | | | | | | | | | | | | Removing the DPSS (gridstorage) driver source code. Description: The DPSS (using Grid-Storage) driver is retired. Removed the configure option with-gridstorage from configure.in. Cvs remove the following files ./src/H5FDdpss.c ./src/H5FDdpss.h ./test/dpss_read.c ./test/dpss_write.c Regenerated Dependencies files (some had to be hand-edited since 'make depend' did not cover them.) Removed reference to DPSS Virtual file driver from H5F.c. Platforms tested: modi4 (Parallel; -with-gass=...), eirene, arabica (fortran, cxx).
* [svn-r4474] Purpose:Albert Cheng2001-09-261-5/+5
| | | | | | | | | | | | New feature. Description: Added a test to verify the correctness of information provided by configure in H5config.h. Some information, such as SIZEOF some types can be hardcoded by config/<machine>. This test verified the information is indeed correct. Currenly, only size of C language types are verified. Platforms tested: Eirene, regular, arabica.

| | | | | | | | | | | | | | | Bug fix Description: "Time" datatypes (H5T_UNIX_D*) were not being stored and retrieved in the datatype object header message correctly. Solution: Store endian-ness and precision in the datatype object header message and added test to continue to track them working correctly. This fixes bug #512. Platforms tested: FreeBSD 4.1.1 (hawkwind)
