* [svn-r27768] Description:Quincey Koziol2015-09-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | Complete revamp of package initialization/shutdown mechanism in the library. Each package now has a single init/term routine. This new way should avoid packages being re-initialized during library shutdown and is also be _much_ more proactive about giving feedback for resource leaks internal to the library. Introduces a new "module" header file for packages in the library (e.g src/H5Fmodule.h) which sets up some necessary package configuration macros for the FUNC_ENTER/LEAVE macros. (The VFL drivers have their own slightly modified version of this header, src/H5FDdrvr_module.h) Also cleaned up a bunch of resources leaks all across the library and tests, along with addressing many warnings, as I encountered them. Tested on: MacOSX/64 10.10.5 (amazon) w/serial & parallel Linux/64 3.10.x (kituo) w/serial & parallel Linux/64 2.6.x (ostrich) w/serial

* [svn-r19174] Bug fix for #1239 - The filter's public function CAN_APPLY ↵Raymond Lu2010-08-051-3/+3
| | | | | | | | | | | | should return htri_t not herr_t. To minimize the change of the library's behavior, in the function H5Z_prelude_callback of H5Z.c, if the return value of can_apply is FALSE and the filter is MANDATE, this function returns a FAILURE. If the return value is FALSE but the filter is OPTIONAL, this function returns a SUCCEED. During the IO, the filter will fail and return a size of zero. But the pipeline will skip this filter. Tested on jam, lnew, and amani. Tested on jam with szip.
* [svn-r16807] Purpose: Fix bug 1533Neil Fortner2009-04-201-1/+1
| | | | | | | | | | | Description: Previously, there was no versioning for H5Z_class_t. This prevented applications written for 1.6 using custom filters from being able to use the 1.8 library. There is now an H5Z_class1_t and H5Z_class2_t to enable compatibility. H5Zregister is *not* versioned, it determines which version of the struct has been passed in by the value of the first field (id or version, both are ints). Tested: jam, linew, smirom (h5committest), jam (--with-default-api-version=v16)
* [svn-r16209] Purpose:Choonghwan Lee2008-12-191-2/+2
| | | | | | | | | | | | | | Bug fix (#1357) Description: Three filters have not assigned correct value to one value-result argument, "buf_size". N-bit, szip, and scale offset filter have had this problem. However, I don't think this problem has been making buffer overrun because those filters were informing the caller that the "buf", another value-result argument, is smaller than it actually is. If there was actual buffer overrun, I believe another problem exists although I don't know. Tested: jam, smirom, linew Although all test were passed, I'm concerned about valgrind memcheck error. There can be another miscommunication between filter and the caller.

* [svn-r8969] Purpose:Quincey Koziol2004-07-301-51/+33
| | | | | | | | | | | | | | | | | | | | | | | | 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. Platforms tested: FreeBSD 4.10 (sleipnir) w/szip Too obscure to require h5committest
* [svn-r8936] Elena Pourmal2004-07-221-5/+5
| | | | | | | | | | | | | | | | 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-r8927] Purpose:Quincey Koziol2004-07-221-8/+8

* [svn-r8915] Elena Pourmal2004-07-211-12/+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-r8781] James Laird2004-07-011-3/+19
| | | | | | | | | | | | | | | | 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:
* [svn-r8731] Purpose:Quincey Koziol2004-06-231-4/+0
| | | | | | | | | | | | | | | 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. Platforms tested: FreeBSD 4.10 (sleipnir) w/gcc34 h5committest
* [svn-r8007] Purpose:Quincey Koziol2003-12-311-0/+4
| | | | | | | | | | | | | | Bug fix Description: Range check the szip 'pixels per block' against the chunk size of the dataset when attempting to create a new dataset, since the szip library requires the PPB to be at least the size of the fastest changing dimension in the chunk. Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest
* [svn-r7820] Purpose:Quincey Koziol2003-11-061-8/+1
| | | | | | | | | | | | Bug fix Description: Don't check the number of szip parameters set during the "can apply" and "set local" callbacks, be safe about setting the parameters instead. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7237] Purpose:Quincey Koziol2003-07-171-1/+4

* [svn-r7126] Purpose:Quincey Koziol2003-06-301-1/+6
| | | | | | | | | | | | | Code cleanup Description: Add in rest of szip "options mask" macros that were missing. Also made "raw" options mask set by the library, instead of requiring users to always set it. Platforms tested: FreeBSD 4.8 (sleipnir) Minor tweaks too small fo h5committest
* [svn-r6900] Purpose:Quincey Koziol2003-05-191-9/+13
| | | | | | | | | | | | | | | | | | | Bug fix Description: Fix three (!) bugs in szip filter: - we were using bytes per pixel instead of bits per pixel - we were using the size of the slowest changing dimension instead of the fastest changing dimension to compute the blocks per scanline parameter - we swapped two parameters when setting up szip_options block. Solution: Addressed bugs above. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest not needed
* [svn-r6644] Purpose:Quincey Koziol2003-04-121-29/+16
| | | | | | | | | | | | | | | | Code cleanup Description: Uncompressed buffers can't get to the szip filter's decompression code now that they are handled correctly by the chunk's filter mask. Solution: Remove handling of uncompressed buffers from szip filter's decompression code. Platforms tested: FreeBSD 4.8 (sleipnir) w/szip h5committest not necessary & doesn't test szip code.
* [svn-r6640] Purpose:Bill Wendling2003-04-111-15/+2
| | | | | | | | | | | | | | | | | | | | | | Fix Description: This is an analogue to the previous bug-fix for filters not being applied to data written but being applied when read. The old way was if the SZlib library couldn't deflate a dataset, then we'd munge along pretending that it was okay. Solution: Trigger it as an error in this situation. The H5Z_pipeline code which calls this function can clear the error stack if need be. Platforms tested: Modi4 (Parallel & Fortran) Burrwhite (Fortran & C++) Baldric (Fortran), but make check didn't work because of "libucb.so" error that I can't fix...) Misc. update:
* [svn-r6611] Purpose:Quincey Koziol2003-04-091-2/+187
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Code cleanup/new features Description: Switch over to a new style for registering filters with the library - instead passing in an ID, a string and a callback function to H5Zregister, the client should pass in a single pointer to a H5Z_claass_t struct which contains the ID, the description string and all the function callbacks as fields. Added support for a new "can apply" callback for each filter, which is called when a dataset is created to check whether the parameters for that filter apply correctly to the combination of the datatype and the chunk size (i.e. dataspace) for the dataset. Added support for a new "set local" callback for each filter, which is called when a dataset is created (after the "can apply" filter callback) and sets filter parameters that are specific to that particular dataset. Switched the filters we ship over to use the new H5Z_class_t struct for their internal registrations and also added "set local" callbacks to the szip and shuffle filters and a "can apply" callback to the szip filter. Lots of other code cleanups, etc. also 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-r6581] Purpose:Quincey Koziol2003-04-031-84/+128
| | | | | | | | | | | | | | | | | | | Code cleanup & bug fix Description: Cleaned up comments & copyright statement. Blocks which were unable to be compressed were missing the "length" prefix, causing the decompression routine to fail. Solution: Always add "length" prefix to all blocks, even ones the fail to compress. Platforms tested: FreeBSD 4.8 (sleipnir) IRIX64 6.5 (modi4) w/parallel Misc. update:
* [svn-r6552] Purpose:MuQun Yang2003-04-011-0/+122
To support szip compression in HDF5 Description: This is where szip filter function is located. Solution: The filter function composes of "encode" and "decode" part, which is similar as deflate filter. One critical difference is: when szip decompresses the data, it needs to know the buffer size to hold the decompressed data in advance. Currently it's hard for HDF5 lib to give the buffer size easily. So to avoid this problem, in each chunk, we add a small header to hold the buffer size of each chunk. The code will use UINT32 ENCODE and UINT32 DECODE to finish this part of work. Platforms tested: Since there are changes of configure.in and configure,I didn't use h5committest. I tested with four platforms. 1) Linux 2.4 (eirene) 2) Solaris 2.7(arabica) 3) windows 2000(VS 6.0) 4) SGI IRIX6.5-64(modi4) For test 1)-3), only basic C tests were done For modi4 test, I tested 64-bit C,parallel and fortran. All tests passed, except a warning message from szip library when checksum is used in some order, which doesn't e any real problems. Misc. update:
