* [svn-r5191] Purpose:Quincey Koziol2002-04-171-0/+3
| | | | | | | | | | | | | | | | | | | 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)

| | | | | Purpose: added description of H5Dset_extent
* [svn-r5170] Raymond Lu2002-04-111-0/+4
| | | | | | | | | | | Purpose: New feature Description: Fill-value's behaviors for contiguous dataset have been redefined. Basicly, dataset won't allocate space until it's necessary. Full details are available at http://hdf.ncsa.uiuc.edu/RFC/Fill_Value, at this moment. Platforms tested: Linux 2.2.
* [svn-r5152] Purpose:Quincey Koziol2002-04-091-0/+2
| | | | | | | | | | | | | | | New Feature Description: Added new H5Dfill() routine to fill the elements in a selection for a memory buffer with a fill value. This is a user API wrapper around some internal routines which were needed for the fill-value modifications from Raymond as well as Pedro's code for reducing the size of a chunked dataset. Platforms tested: FreeBSD 4.5 (sleipnir) [and IRIX64 6.5 (modi4) in parallel, in a few minutes]

* [svn-r5147] Raymond Lu2002-04-051-0/+3
| | | | | | | | | | Purpose: New feature Description: Added a query function H5Tget_member_index for compound and enumeration data types, to retrieve member's index by its name. Platforms tested: Linux 2.2
* [svn-r5138] Purpose:Quincey Koziol2002-04-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | Bug Fix & Code Cleanup Description: The MPI-IO optimized transfer routines (H5S_mpio_spaces_read/H5S_mpio_space_write) are not being invoked in all the cases where they could be used. Additionally, the code for determining if an optimized transfer is wrapped into the actual I/O transfer routine in a very confusing way. Solution: Re-enabled MPI-IO optimized transfer routines in all the cases where they should work. Extracted all the pre-conditions for optimized transfers into separate routines from the transfer routines. Platforms tested: FreeBSD 4.5 (sleipnir) & IRIX64 6.5 (modi4)
* [svn-r5130] Purpose:Quincey Koziol2002-04-021-167/+172
| | | | | | | | | | | | | | | | | | | | | | Bug Fix & Feature Description: The selection offset was being ignored for optimized hyperslab selection I/O operations. Additionally, I've found that the restrictions on optimized selection I/O operations were too strict and found a way to allow more hyperslabs to use the optimized I/O routines. Solution: Incorporate the selection offset into the selection location when performing optimized I/O operations. Allow optimized I/O on any single hyperslab selection and also allow hyperslab operations on chunked datasets. Platforms tested: FreeBSD 4.5 (sleipnir)

* [svn-r5124] Raymond Lu2002-04-011-0/+2
| | | | | | | | | | | | Purpose: Bug fix(#697) Description: Variable-length string is not treated as string. Solution: Added character set and padding as VL string's attributes. They can be set and retrieved. Platforms tested: Solaris 8, IRIX64 6.5 parallel, and FreeBSD.

* [svn-r4965] Purpose:Quincey Koziol2002-02-141-0/+3
| | | | | | | | | | | | | Bug Fix Description: If a non-zero fill-value is used for a chunked dataset, any non-existent chunked read with an "all" selection (or a contiguous hyperslab selection) will return zero for those instead of the user's fill-value. Solution: Fixed I/O code to pass down fill-value to "optimized" I/O routines, so it will be available to fill the user's buffer with. Platforms tested: FreeBSD 4.5 (sleipnir)

* [svn-r4891] Purpose:Quincey Koziol2002-01-311-0/+3
| | | | | | | | | | | | | | | Code speedup Description: Chunking I/O routines are reading in an entire chunk when performing I/O on the chunk, even if the chunk will be too large to cache. Solution: If the chunk is too large to cache, uncompressed and has been allocated space in the file, or if we are using the MPI-I/O VFD, perform the I/O directly to the chunk, instead of reading the chunk into memory, updating it and immediately writing the entire chunk back out. Platforms tested: FreeBSD 4.5 (sleipnir) (using serial access) and IRIX64 6.5 (modi4) (using parallel access with MPI-I/O)

* [svn-r4851] Purpose:Quincey Koziol2002-01-231-0/+2
| | | | | | | | | | | | | | | | | | 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-r4747] Purpose:Quincey Koziol2001-12-201-0/+5
| | | | | | | | | | | | | | Bug Fix. Description: The H5Rget_object_type function could not get the object type for dataset region references. Solution: Added a new function, H5Rget_obj_type, to replace H5Rget_object_type. The new function requires the reference type as an additional parameter, in order to allow queries on different reference types to be performed correctly. Platforms tested: FreeBSD 4.4. (sleipnir)

* [svn-r4706] Purpose:Quincey Koziol2001-12-121-0/+2
| | | | | | | | | | | | Code cleanup Description: Tweaked internal error handling macros to reduce the size of the library's object code by about 10-20%. Also cleaned up some compiler warnings... Platforms tested: FreeBSD 4.4 (sleipnir)
* [svn-r4695] Purpose:Quincey Koziol2001-12-111-0/+2
| | | | | | | | | | | | | | | | | | Bug Fix Description: The file metadata macros generate unaligned access warnings on the IA64 architecture. Solution: Got rid of bogus big-endian vs. little-endian differentiation when encoding and decoding file metadata and use proper set of macros to prevent unaligned access problems. This fixes bug #672. Platforms tested: FreeBSD 4.4 (sleipnir)
* [svn-r4693] Purpose:Quincey Koziol2001-12-111-0/+3
| | | | | | | | | | | | | | | | | | | | Bug Fix Description: The code in H5Sselect_hyperslab_valid contained an fencepost error and is allowing selections which overlap the extent by exactly one element in any dimension to pass as valid instead of flagging the selection as invalid. This bug only affects hyperslabs which have been OR'ed together, not the selection from a single H5Sselect_hyperslab. This fixes bug #550. Solution: Changed an '>' to an '>=' and added new regression test to check for error. Platforms tested: FreeBSD 4.4 (sleipnir)
* [svn-r4680] Purpose:Quincey Koziol2001-12-061-0/+2
| | | | | | | | | | | | | Code cleanup Description: Property that H5P(g|s)et_hyper_cache uses is no longer in use inside the library. Solution: Removed H5P(g|s)et_hyper_cache API functions, except when backward compatibility is turned on. When backward compatibility is turned on, the property is defined by the library, but unused internally. Platforms tested: FreeBSD 4.4 (sleipnir)

* [svn-r4601] Purpose:Quincey Koziol2001-11-121-0/+2
| | | | | | | | | | | | Document bug fix. Description: The internal B-tree code was dumping core with an assertion failure when flushing data to the file if too many objects were put into the same B-tree (forcing the root node to split, I think). Solution: Fixed the B-tree copy routine to copy the correct number of raw keys. Platforms tested: FreeBSD 4.4 (hawkwind), Solaris 2.6 (baldric)
