* [svn-r9054] Purpose:Quincey Koziol2004-08-082-27/+45
| | | | | | | | | | | | | | | | | | | Bug fix Description: Correct possible core dump when a datatype conversion function is registered with the library after a compound datatype has been converted (having it's type conversion information cached by the library). The compound datatype must have been created by inserting the fields in non-increasing offset order to see the bug. Solution: Re-sort the fields in the compound datatypes before recalculating the cached information when performing the conversion on them. Platforms tested: FreeBSD 4.10 (sleipnir) h5committested

| | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix (Failures when dataset size >= 1 GB, reported by Bill Loewe.) Description: In the IBM AIX system using 32bit mode, if a dataset size was 1GB or larger, when the "end" of the dataset was selected, MPI would complain it could not keep the Upper bound of a datatype within the range of MPI_Aint. This was because the old algorithm would derive the selection with extent of each row first. After all dimensions were processed, it then calculate the start position and just displace the whole MPI derived type. So, the final MPI type was actually the start position plus the whole dataset. Since the start can be as big as the whole dataset, this made the final derived twice as big as 1GB. That would hit the 2GB MPI_Aint range limit in the 32 bit mode. Solution: Use a different algorithm to include the start position in the defining of MPI type for each dimension. When all dimensions are processed, the MPI type represents the selection exactly.

* [svn-r8970] Purpose:Quincey Koziol2004-07-302-50/+35
| | | | | | | | | | | | | | | | | | | | | | | | Bug fix. Description: Address two problems: - The computation of the scanline in the szip filter was being performed in the "can apply" callback routine instead of the "set local" routine. - The routine which allocated all the chunks for an entire dataset (which is invoked when the allocation time is early or late, rather than incremental) wasn't recording a failed filter in the information for the chunk, causing the library to believe that the chunk had the filter applied when it really hadn't. Solution: - Move the scanline computation to the "set local" callback. - Record the filter mask with each chunk created when allocating them.

| | | | | | | | | | | | | | | Bug fix Description: Allow I/O on extendible chunked datasets with (currently) zero-sized dimensions to proceed harmlessly instead of dumping core on an assertion. Solution: Removed assertion and added checks to avoid problem situation in H5TB_end Platforms tested: FreeBSD 4.10 (sleipnir) w/ & w/o parallel Too minor to require h5committest

| | | | | | | | | | | | | Bug fix Description: Always write fill values to chunks when initializing entire B-tree and any filters are defined. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r8954] James Laird2004-07-275-1/+60
| | | | | | | | | | | | | | | | 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-r8947] Purpose:Quincey Koziol2004-07-265-16/+49
| | | | | | | | | | | | | | | | | | Code cleanup, sorta Description: Added ifdef sections for "H5_USING_PURIFY" in various places in the code, which are designed to reduce the spurious "uninitialized memory read" warnings from purify which are actually OK. Note that this macro will have to be turned on by adding it to the CFLAGS for the build - I didn't think it was important enough to add a configure flag for. Also, the changes in H5HG.c optimize the walks through the objects in a heap to only look at the 'used' entries instead of all the 'allocated' entries.

| | | | | | | | | | | | | | Code optimization Description: Changed calloc() calls to malloc() calls allocating background buffers during dataset writes, since the background buffer information will be read from disk anyway, overwriting any existing values.

* [svn-r8939] Purpose:Albert Cheng2004-07-231-3/+3
| | | | Updated the library version to 1.6.3-snap0.
* [svn-r8937] James Laird2004-07-232-4/+10
| | | | | | | | | | | | | | | | | | | Purpose: Bug fix Description: Modification time test (mtime) would die silently on some systems. This is because the code is very system-dependant (it relies on getting the current time and the timezone from the OS). Solution: mtime test now uses TEST_ERROR macro to print "FAILED" and to output where the failure occurred. Configure script is a little smarter about whether gettimeofday() function returns the timezone correctly. Further bugs will need to be addressed on a system-by-system basis. Platforms tested: sleipnir, arabica, verbena, copper, windows (VC7)
* [svn-r8935] Elena Pourmal2004-07-221-6/+6
| | | | | | | | | | | | | | | | Purpose: Bug fix Description: While working on the SZIP documentation with Frank, I realized that when scanline was less than 4k and bigger than pixels_per_block, it was not adjusted if number_of_blocks_per_scanline was bigger than max_number_of_blocks_per_scanline. Solution: Fixed the code. Unfortunately it didn't help with the problem I had using h5repack with DOQGROD.he5 file. Platforms tested: copper Misc. update:
* [svn-r8917] Elena Pourmal2004-07-211-10/+28
| | | | | | | | | | | | | | | | | | Purpose: Improvement Description: HDF5 Library set pixels_per_scanline parameter to the size of the chunk's fastest changing dimension. As a result, fastest changing dimension of the chunk could not be bigger than 4K and smaller than pixels_per_block value and szip compression couldn't be used for many real datasets. Solution: Reworked algorithm how HDF5 sets pixels_per_scanline value; only chunks with the total number of elements less than pixels_per_block value are rejected. There is no restriction on the size of the chunk's fastest changing dimension anymore. Platforms tested: verbena, copper, sol Misc. update:
* [svn-r8902] Purpose:Quincey Koziol2004-07-201-6/+3
| | | | | | | | | | | | Bug fix Description: Allow buffer parameter to H5Dread & H5Dwrite to be NULL if there are no elements to transfer. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8900] James Laird2004-07-201-0/+3
| | | | | | | | | | | | | | Purpose: Bug Fix Description: H5Sset_extent_simple causes errors if used to reduce a space's maxdims to zero. Solution: H5Sset_extent_simple now cleans up the pointer. Added a regression test. Platforms tested: sleipnir (very minor change)
* [svn-r8898] James Laird2004-07-201-0/+7
| | | | | | | | | | | | | | | Purpose: Bug Fix Description: Trying to create the root group or the working group ("/" or ".") fakes out HDF5 so that it neither creates a group nor returns an error. Solution: H5G_namei now throws an error if it was supposed to insert but didn't. Platforms tested: sleipnir, Visual Studio 7 (very minor change)
* [svn-r8893] Purpose:Quincey Koziol2004-07-1613-483/+825

* [svn-r8876] James Laird2004-07-149-13/+202
| | | | | | | | | | | | | | | | | | | | | | Purpose: Bug Fix Description: If an HDF5 file grows larger than its address space, it dies and is unable to write any data. This is more likely to happen since users are able to change the number of bytes used to store addresses in the file. Solution: HDF5 now throws an error instead of dying. In addition, it "reserves" address space for the local heap and for object headers (which do not allocate space immediately). This ensures that after the error occurs, there is enough address space left to flush the entire file to disk, so no data is lost. A more complete explanation is at /doc/html/TechNotes/ReservedFileSpace.html Platforms tested: sleipnir, copper (parallel), verbena, arabica, Windows (Visual Studio 7) Misc. update:
* [svn-r8875] Purpose:Quincey Koziol2004-07-145-110/+192
| | | | | | | | | | | | | | | | | | | | Bug fix Description: Correct problems with "resurrecting" a dataset in a file. (This occurs when a dataset which is open gets unlinked from the group hierarchy (making it "dead" and marked for deletion in the file) and then is re-linked to the group hierarchy). Note that the current solution applies only to datasets, further work will fix this for groups and named datatypes also. Also, fix the "debug" routines to be a little more helpful in certain situations. Additionally, fix a locking bug in the symbol table node splitting routine which could be [one of] the cause[s] of the file corruption in flexible parallel operation. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel h5committested
* [svn-r8868] Purpose:Quincey Koziol2004-07-131-3/+13
| | | | | | | | | | | | | | | | | | | Bug fix Description: Fix error in chunked dataset I/O where data written out wasn't read correctly from a chunked, extendible dataset after the dataset was extended. Also, fix parallel I/O tests to gather error results from all processes, in order to detect errors that only occur on one process. Solution: Bypass chunk cache for reads as well as writes, if parallel I/O driver is used and file is opened for writing.

* [svn-r8866] Purpose:Quincey Koziol2004-07-134-74/+126
| | | | | | | | | | | | | | | | | Code optimization Description: Re-work the insertion of a new child into an existing node, to exploit some speedups for adding the rightmost child, since this is a very common case when appending records to an unlimited size dataset. Also, hoist the checks for the tree's 'K' value into a field in the shared information about the tree, instead of re-calculating them all the time.

* [svn-r8854] Purpose:Quincey Koziol2004-07-109-341/+375
| | | | | | | | | | | | | | | | | | | | Code optimization Description: Refactor B-tree code to extract all common information for a B-tree into a shared structure that is pointed to by all the nodes in tree (instead of being included in each node). Also re-order B-tree node comparison checks for chunked datasets to check for >= the upper node first, since the comparison is a bit "heavy" and this check is more likely to succeed when you are adding records to the dataset. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest (also, recent h5dump commits have broken testing...)
* [svn-r8848] Purpose:Quincey Koziol2004-07-091-69/+20

* [svn-r8846] Purpose:Quincey Koziol2004-07-0911-43/+130
| | | | | | | | | | | | | | | | | | Bug fix Description: The "shared" raw B-tree node can get freed before all the B-tree nodes had been flushed out to disk and released by the cache. Solution: Implement a simple reference counting wrapper for objects in the library and use it to hold the shared raw B-tree nodes so they aren't freed before all references to them in memory are released. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) IRIX64 6.5 (modei4)

* [svn-r8824] Purpose:Quincey Koziol2004-07-0710-416/+405
| | | | | | | | | | | | | | | Code optimization Description: Since the raw B-tree nodes are the same size and only used when reading in or writing out a B-tree node, move raw B-tree node buffer from being per node to a single node that is shared among all B-tree nodes of a particular tree, freeing up a lot of space and eliminating lots of memory copies, etc. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest

* [svn-r8775] James Laird2004-06-301-0/+4
| | | | | | | | | | | | | | | | | | | Purpose: Fixed a bug that broke daily tests. SZIP now always uses K13 compression. Description: When configured with the --srcdir option, dsets test would look for a test file in the same directory as the test, instead of in the directory that contains the source files. SZIP never needs to use CHIP compression, so the option to set this flag instead of K13 compression has been removed. Platforms tested: Copper
