| | | | | | | | | | | Code optimization Description: Query the dataset creation and transfer properties less often. Platforms tested: Solaris 2.7 (arabica) h5committested
* [svn-r8314] Purpose: Progressive check-inRaymond Lu2004-04-061-2/+4
| | | | | | | | | | Description: NULL dataspace. This step is mainly for dataspace header message and a test. Solution: The test mainly checks NULL dataspace features. Backward compatibility is tested in the fill value test. Platforms tested: h5committest

* [svn-r8158] Purpose:Quincey Koziol2004-02-061-5/+15
| | | | | | | | | | | | | | | | | Code cleanup/optimization Description: Query property list values once, at the beginning of the I/O routines, instead of querying the property list values multiple (lots!) of times in lower level routines. Solution: Create "property list caches" for internal library queries of the property list values. Platforms tested: IBM p690 (copper) w/parallel & fphdf5 h5committest
* [svn-r8127] Purpose:Quincey Koziol2004-01-311-0/+4
| | | | | | | | | | | Bug fix Description: Fix a couple of bugaboos in the serial build that crept in Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r8082] Purpose:Quincey Koziol2004-01-191-2/+6
| | | | | | | | | | | | | Bug fix Description: Tweak address comparison of external file list's heap address a bit to pacify Windows. Platforms tested: FreeBSD 4.9 (sleipnir) Asking Pedro to test on Windows Too minor to require h5committest
* [svn-r8057] Purpose:Quincey Koziol2004-01-131-1/+5
| | | | | | | | | | | Bug fix Description: Plug another small memory leak for fill-values. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r8038] Purpose:Quincey Koziol2004-01-081-35/+259
| | | | | | | | | | | | | | | | | | | | Bug fix Description: When two property lists are compared, the H5Pequal routine was just comparing the raw information for the property values. This causes problems when the raw information contains pointers to other information. Solution: Allow a 'compare' callback to be registered for properties, so that a user application get perform the comparison itself, allowing for "deep" compares of the property value. This was exported to the H5Pregister & H5Pinsert routines in the development branch, but not the release branch. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r8026] Purpose:Quincey Koziol2004-01-061-0/+4
| | | | | | | | | | | | | | | Bug fix Description: Fix small memory leak of fill-value information inside the library. Solution: "reset" the fill-value object header message, so that the internal buffer gets freed. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7917] Purpose:Quincey Koziol2003-12-061-18/+14
| | | | | | | | | | | | | | | | | | | 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-r7829] Purpose:Quincey Koziol2003-11-081-13/+16
| | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Allowing the library to call malloc with a size of 0 bytes causes problems for some users, so we check for allocations of 0 bytes and disallow them now. Cleaned up some code which could call malloc with 0 size. Changed some code calling HDmalloc directly to call H5MM_malloc(), which allows us to check for 0 sized allocations. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7725] Purpose:Quincey Koziol2003-10-241-21/+29
| | | | | | | | | | | | Code cleanup Description: Refactored handlier of VFL drivers in file access and data transfer property lists in order to simplify and unify the code dealing with them. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7626] Purpose:Quincey Koziol2003-10-141-0/+1
| | | | | | | | Update dependencies and tracing information Platforms tested: Linux 2.4 (verbena) w/FORTRAN too minor for h5committest
* [svn-r7498] Purpose:Quincey Koziol2003-09-191-2/+1
| | | | | | | | | | | Code cleanup Description: Clean up various warnings and parameter mis-matches, etc. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to need h5committest
* [svn-r7495] Purpose:Bill Wendling2003-09-191-14/+0
| | | | | | | | | | | | | | | | Removed Dead Code Description: Some of the FPHDF5 code was dead (I thought it'd be useful at one point, but was wrong). Solution: Removed Platforms tested: Linux (FPHDF5 specific. No need for h5committest) Misc. update:
* [svn-r7489] Purpose:Bill Wendling2003-09-181-98/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r7453] Purpose:Quincey Koziol2003-09-101-4/+2
| | | | | | | Checkpoint file format spec. Description: Clarifications and cleanups related to file format review.
* [svn-r7384] Purpose:Quincey Koziol2003-08-191-22/+28
| | | | | | | | | | | Code cleanup Description: More linting... Platforms tested: FreeBSD 4.8 (sleipnir) too minor to need h5committest
* [svn-r7373] Purpose:Quincey Koziol2003-08-151-1/+1
| | | | | | | | | | | | Code cleanup Description: Cleanup H5Pclose code and also switch a few internal users of H5Pclose to use H5I_dec_ref instead. Platforms tested: FreeBSD 4.8 (sleipnir) too small for h5committest
* [svn-r7370] Purpose:Quincey Koziol2003-08-151-1/+21
| | | | | | | | | | | | | Code cleanup & commentary Description: Add comments to the recent FPHDF5 additions to this file to describe why the changes shouldn't be in this file and attempt to find the proper home for them. Platforms tested: FreeBSD 4.8 (sleipnir) just comments mostly, no need to run h5committest
* [svn-r7367] Purpose:Bill Wendling2003-08-151-0/+74
| | | | | | | | | | | | | | | | | | | Update Description: Added an extra flag to the clear functions that triggers a "destroy" of the object being cleared if necessary. This is a fix for the FPHDF5 stuff which had an object sticking around after it was cleared. (In FPHDF5, some processes are in charge of destroying the object, but all processes might actually allocate the object.) Platforms tested: AIX (Copper: Fortran & C++) Linux (Verbena: Fortran & C++) IRIX (Modi4: Parallel & Fortran) (Sol is down) Misc. update:
* [svn-r7334] Purpose:Quincey Koziol2003-08-111-6/+6
| | | | | | | | | | | | | | Bug fix Description: Object references were not getting written out correctly to the file, with recent changes to their memory structure. Solution: Convert the object references correctly. Platforms tested: h5committested
* [svn-r7297] Purpose:Quincey Koziol2003-08-081-4/+4
| | | | | | | | | | | | | | | | Code cleanup Description: Changed lines like: H5E_clear(H5E_get_my_stack()); to: H5E_clear(NULL); which performs the same operation. Platforms tested: h5committested

* [svn-r7243] Purpose:Quincey Koziol2003-07-211-6/+19
| | | | | | | | | | | | Bug fix Description: Fix bug with combination of fill-values, chunked datasets and variable-length strings. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7211] Purpose:Quincey Koziol2003-07-111-433/+483
| | | | | | | | | | | Code cleanup Description: Various code cleanups suggested by lint tool Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7181] Purpose:Quincey Koziol2003-07-071-14/+0
| | | | | | | | | | | Version update Description: Removed 1.4 compatibility code in the library. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7116] Purpose:Quincey Koziol2003-06-271-3/+4
| | | | | | | | | | | | Update code Description: Move "PABLO_MASK" definition above header file inclusion to avoid problems with inline functions in header files. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7058] Purpose:Quincey Koziol2003-06-181-22/+25
| | | | | | | | | | | | | | Bug fix and refactored code Description: Return the file space we have allocated already when a dataset creation fails. Also track the change to the H5Fget_obj_<foo> APIs Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7037] Purpose:Quincey Koziol2003-06-131-1/+4
| | | | | | | | | | | | | | | | | | Bug fix Description: The fill time in a dataset with no fill value information created with an older version of the library was getting set to H5D_FILL_TIME_ALLOC instead of the new default H5D_FILL_TIME_IFSET and was causing H5Dcreate() calls with that dataset creation property list to fail now. Solution: Set the new default in the fill time initialization for missing fill value information. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7029] Purpose:Quincey Koziol2003-06-121-20/+52
| | | | | | | | | | | | | New feature/Bug fix Description: Add new fill time value - H5D_FILL_TIME_IFSET which writes the fill value to a dataset if the user has defined one, otherwise not writing the fill value to the dataset. Platforms tested: FreeBSD 4.8 (sleipnir) serial & parallel h5committest
* [svn-r7016] Purpose:Quincey Koziol2003-06-101-17/+30
| | | | | | | | | | | | | | | | Bug fix Description: Chunked datasets with early space allocation and unlimited dimensions were running into problems where the dataset's "layout" message was marked as constant too early, preventing the dataset's dimensions from being extended. Solution: Change logic for marking the layout message constant to wait a bit longer. Platforms tested: FreeBSD 4.8 (sleipnir) w/parallel h5committest
* [svn-r6878] Purpose:Quincey Koziol2003-05-151-3/+3
| | | | | | | | | | | Code cleanup Description: Limit the scope on more function prototypes/macros/typedefs. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest not necessary.
* [svn-r6869] Purpose:Quincey Koziol2003-05-131-1/+23
| | | | | | | | | | | | | | | | | Bug fix. Description: When the same dataset is opened more than once and those references to the object are left dangling, the library would not correctly shut down the dataset API, potentially allowing the file to be truncated. Solution: "force" the dataset IDs to be released when the dataset API is being shut down by the library. Platforms tested: FreeBSD 4.8 (sleipnir) h5committested
* [svn-r6837] Purpose:Quincey Koziol2003-05-081-4/+15
| | | | | | | | | | | | | | | Code cleanup. Description: Move many package or internal function prototypes and macro definitions into tighter scope according to their current use. Added more comments where appropriate. Eliminate ancient, unused functions. Added a couple "accessor" functions to get parts of data structures which were moved out of scope. Platforms tested: h5committested
* [svn-r6825] Purpose:Quincey Koziol2003-05-071-1208/+7
| | | | | | | | | | | | | | | | | | | | | | | | | New feature/enhancement Description: Chunked datasets are handled poorly in several circumstances involving certain selections and chunks that are too large for the chunk cache and/or chunks with filters, causing the chunk to be read from disk multiple times. Solution: Rearrange raw data I/O infrastructure to handle chunked datasets in a much more friendly way by creating a selection in memory and on disk for each chunk in a chunked dataset and performing all of the I/O on that chunk at one time. There are still some scalability (the current code attempts to create a selection for all the chunks in the dataset, instead of just the chunks that are accessed, requiring portions of the istore.c and fillval.c tests to be commented out) and performance issues, but checking this in will allow the changes to be tested by a much wider audience while I address the remaining issues. Platforms tested: h5committested, FreeBSD 4.8 (sleipnir) serial & parallel, Linux 2.4 (eirene)
* [svn-r6738] Purpose:Quincey Koziol2003-04-231-1/+2
| | | | | | | | | | | | Code cleanup Description: Add & improve assertion that was removed in last commit, to check for compact dataset storage. Platforms tested: FreeBSD 4.8 (sleipnir) triple check not necessary.
* [svn-r6729] Raymond Lu2003-04-221-3/+2
| | | | | | | | | | | Purpose: bug fix Description: VL datatype in compact dataset fails because a wrong type size is used. Platforms tested: h5committested Misc. update:
* [svn-r6659] Purpose:Quincey Koziol2003-04-141-3/+4
| | | | | | | | | | | | | | | | New feature, sorta Description: Track changes to various internal APIs 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/parallel & FORTRAN (h5committest not run due to my ongoing difficulties with C++ on burrwhite).
* [svn-r6604] Purpose:Quincey Koziol2003-04-091-30/+45
| | | | | | | | | | | | | | | | | | New feature Description: Hooked up internal dataset creation call (H5D_create) to the new "can apply" and "set local" callbacks for filters. Solution: Platforms tested: FreeBSD 4.8 (sleipnir) w/szip Linux 2.4 (sleipnir) w/szip Solaris 2.7 (arabica) w/FORTRAN IRIX64 6.5 (modi4) w/szip, FORTRAN & parallel Misc. update:
* [svn-r6499] Purpose:Bill Wendling2003-03-191-17/+18
| | | | | | | | | | | | | Update Description: Added support for FPHDF5 wherever there was support for MPI/IO and/or MPIPOSIX. Platforms tested: Linux, Modi4, Sol Misc. update:
* [svn-r6411] Purpose:Quincey Koziol2003-02-171-42/+42
| | | | | | | | | | | | | | | | | | | | | | 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-r6388] Purpose:Quincey Koziol2003-02-101-2/+2
| | | | | | | | | | | | | Update feature Description: Relax collective constraint for API functions which only read metadata from a file. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 w/parallel
* [svn-r6387] Purpose:Quincey Koziol2003-02-101-132/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r6375] Raymond Lu2003-02-041-0/+12
| | | | | | | | | | | Purpose: New feature Description: Added Adler32 checksum as a filter in pipeline Platforms tested: arabica (fortran), eirene (, C++), modi4 (parallel, fortran) Misc. update: Update release_docs/RELEASE.
* [svn-r6308] Purpose:Quincey Koziol2003-01-211-0/+8
| | | | | | | | | | | | | | | | | 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)
* [svn-r6296] Purpose:Quincey Koziol2003-01-171-15/+21
| | | | | | | | | | Code cleanup Description: Reduce warnings on Windows Platforms tested: FreeBSD 4.7 (sleipnir)
* [svn-r6266] Purpose:Quincey Koziol2003-01-101-49/+49
| | | | | | | | | | | | Code cleanup/new feature. Description: Split FUNC_LEAVE into API and non-API specific versions. This allows a solution to compiling this branch with C++, as well as reducing the size of the binaries produced. Platforms tested: FreeBSD 4.7 (sleipnir) w/serial, parallel (including MPE) & thread-safe
* [svn-r6255] Purpose:Quincey Koziol2003-01-091-5/+5
| | | | | | | | | | Code cleanup Description: Clean up a few more warnings and update dependencies. Platforms tested: Linux 2.2.18smp (eirene) serial & parallel
