* [svn-r9563] Purpose:Quincey Koziol2004-11-231-23/+18
| | | | | | | | | | | | | Code optimization Description: Change how default allocation time is handled internally to the library, to avoid some performance issues with property lists. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r9556] Purpose:Quincey Koziol2004-11-221-2/+2
| | | | | | | | | | | | | | | | | | | | | Code cleanup & optimization Description: Improve ADF/CGNS benchmark by reducing the number of internal attribute copies made during creations, opens and writes. Added new H5O_iterate() routine for iterating through messages of a certain type in the object header (attributes are the only message currently that can have multiple instances in the object header). Cross-pollinated various minor code cleanups to reduce diffs between branches. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r9358] Purpose:Quincey Koziol2004-10-041-4/+0
| | | | | | | | | | | | | | | Bug fix Description: Relax restrictions on parallel I/O to allow compressed, chunked datasets to be read in parallel (collective access will be degraded to independent access, but will retrieve the information still). Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) IRIX64 6.5 (modi4) h5committest
* [svn-r9354] Purpose:Quincey Koziol2004-10-011-23/+23
| | | | | | | | | | | | | | | | Bug fix & code cleanup Description: More dataset cleanups to get to a point where we can fix the chunked I/O bug. Also fix a couple of errors in the recent file object resurrection changes which should hopefully address the recent daily test failres (H5T.c) Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) h5committest
* [svn-r9342] Purpose:Quincey Koziol2004-09-301-18/+56
| | | | | | | | | | | | | | | | Bug fix/code cleanup Description: Clean up raw data I/O code to bundle the I/O parameters (dataset, DXPL ID, etc) into a single struct to pass around through the dataset I/O routines, since they are always passed together, until very near the bottom of the I/O stack. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) IRIX64 6.5 (modi4) h5committest
* [svn-r9329] James Laird2004-09-281-270/+307
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip. Platforms tested: Visual Studio 7, sleipnir, arabica, verbena Misc. update:
* [svn-r9183] Purpose: New featureRaymond Lu2004-09-011-4/+4
| | | | | | | | | | | | Description: Restore 6 old error API functions back to the library to be backward compatible with v1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, H5Eset_auto, H5Eget_auto. These functions do not have error stack as parameter. Solution: Internally, these functions use default error stack. Platforms tested: h5committest and fuss. Misc. update: RELEASE.txt
* [svn-r9101] Purpose:Quincey Koziol2004-08-171-15/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix Description: 1 - Dataset contiguous storage cache information had a bug where it was possible to try to access invalid cache information if the cache wasn't filled the first time it attempted to loop through the list of offset/length vectors. 2 - Additionally, the contiguous storage cache information was being used in certain circumstances from the chunked dataset I/O code path, which was generally fatal since the chunk storage and contiguous storage information were stored together in a union. Solution: 1 - Avoid special case of first trip through loop over offset/length I/O vectors and always check for the contiguous storage sieve buffer buffer being NULL. 2 - Change the union containing the chunk and contiguous storage cache information into a struct, allowing both to be used at the same time.

* [svn-r8953] James Laird2004-07-271-0/+6
| | | | | | | | | | | | | | | | Purpose: Bug fix Description: When a simple dataspace is created, its extent should be set before using it, or it will silently function as a NULL dataspace. Solution: Added checks on user-supplied dataspaces. Now dataspaces without extents set will throw errors; users must explicitly set a dataspace to be NULL. Platforms tested: sleipnir, windows
* [svn-r8801] Purpose:Quincey Koziol2004-07-031-36/+91
| | | | | | | | | | | | | | | Code optimization Description: Set up datatype ID for dataset's datatype on disk. This allows us to avoid repeatedly copying the datatype when an ID is needed. Also, clean up a few warnings in various other places. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8781] James Laird2004-07-011-6/+61
| | | | | | | | | | | | | | | | Purpose: HDF5 now supports SZIP with no encoder. Description: SZIP can be configured to have both encoder and decoder or just to have the decoder. HDF5 can now query the configuration of any filter, and will throw errors if users try to write using a filter with encoding disabled. Solution: Added H5Zget_filter_info function, changed API for H5Pget_filter and H5P_get_filter_by_id. See SZIP RFC. Platforms tested: Copper (fortran, C++, parallel), Sleipnir (C++), Arabica (fortran, C++), Verbena (fortran, C++) Misc. update:

| | | | | | | | | | | | | | | Code cleanup & minor optimization Description: Re-work the way interface initialization routines are specified in the library to avoid the overhead of checking for them in routines where there is no interface initialization routine. This cleans up warnings with gcc 3.4, reduces the library binary size a bit (about 2-3%) and should speedup the library's execution slightly.

| | | | | | | | | | | | | Code optimization Description: Avoid making copy of default vlen allocation info when default DXPL is used. Just retarget pointer to point to default info directly. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8686] Purpose:Quincey Koziol2004-06-141-3/+4
| | | | | | | | | | | | | Code optimization Description: Eliminate memcpy() when using default DXPL by pointing at existing default object, instead of copying it. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8673] Purpose:Quincey Koziol2004-06-131-7/+7
| | | | | | | | | | | | | | | | | | Code optimization Description: Revised dataspace selections to use a more "object oriented" mechanism to set the function pointers for each selection and selection iterator. This reduces the amount and number of times that dataspace selection info has to be copied. Additionally, change hyperslab selection information to be dynamically allocated instead of an inline struct.

* [svn-r8613] Purpose:Quincey Koziol2004-06-051-87/+143
| | | | | | | | | | | | | | | | | Refactor code Description: Move chunk and contiguous cached raw data from file information to dataset information. This simplifies a number of internal interfaces, aligns the code with it's purpose better and should allow more optimizations to the chunked data I/O performance. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) h5committest Misc. update:
* [svn-r8600] Purpose:Quincey Koziol2004-05-311-13/+21
| | | | | | | | | | | | | Code optimization Description: Don't recompute the internal index value for looking up the chunk in the hash table, just use the value already computed from iterating through the chunks. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8590] Purpose:Quincey Koziol2004-05-271-119/+129
| | | | | | | | | | | | | | | | | | | | | Code optimization & bug fix Description: When dimension information is being stored in the storage layout message on disk, it is stored as 32-bit quantities, possibly truncating the dimension information, if a dimension is greater than 32-bits in size. Solution: Fix the storage layout message problem by revising file format to not store dimension information, since it is already available in the dataspace. Also revise the storage layout data structures to be more compartmentalized for the information for contiguous, chunked and compact storage. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel Solaris 2.7 (arabica) h5committest
* [svn-r8544] Purpose:Quincey Koziol2004-05-201-2/+2
| | | | | | | | | | | | | | Code optimization Description: Expand the use of macros to inline trivial function pointer lookup and calls to reduce the overall number of functions invoked during normal operation of the library.

| | | | | | | | | | | | | Code optimization Description: Further reduce the number of copies we make of a hyperslab selection for chunked I/O, especially when we are only going to throw the old selection away for a new one. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8488] Purpose:Leon Arber2004-05-061-1/+0
| | | | | | | | | | | | | | | | | | | Bug fix. Description: Fixed handling of trivial data transform expressions (like 5/3 + 3) and some data coversion fixes. Also added more tests to dtransform.c Solution: Added some more checks in the H5Z_xform_reduce_tree function to see if perhaps the transform expression is complicated and is a non-trivial reduction. Added tests for data conversion to dtransform as well as tests for a trivial data transform expression. Platforms tested: h5committest'ed, except used arabica instead of sol and didn't do on copper b/c no logon there. Problem noted with mtime test...doesn't appear to be related to anything having to do with data transforms.

| | | | | | | | | | | | | | | | | 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-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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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:
