* [svn-r28646] Minor normalization with revise_chunks.Dana Robinson2015-12-141-1/+0
| | | | | | | | | Also purged obsolete /*ARGSUSED*/ from the library. Tested on: Ubuntu 15.10 (Linux 4.2.0 x86_64) gcc 5.2.1 serial only (these changes have been in revise_chunks for a long time)
* [svn-r27768] Description:Quincey Koziol2015-09-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | 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-r27133] - Add a new attribute function characterstic for format:Mohamad Chaarawi2015-06-011-1/+1
| | | | | | | | * H5_ATTR_FORMAT(X,Y,Z) __attribute__((format(X, Y, Z))) - Rename UNUSED attribute characterstic to H5_ATTR_UNUSED. - Rename NORETURN attribute characterstic to H5_ATTR_NORETURN tested with h5committest.
* [svn-r26329] Merge of r26069, r26070, and r26072 from the ↵Dana Robinson2015-02-271-3/+0
| | | | | | | | | | | | | | | | | | features/autotools_rework branch. Removed the configure option that allows selective disabling of individual internal filters (fletcher32, shuffle, etc.). This feature mucked up the code with a lot of #ifdefs, saved very little space, and was not scalable to a general scheme for library size reduction. We've decided to remove the feature while we investigate a more general scheme for decreasing the library size. Part of: HDFFV-9086 Tested on: h5committest
* [svn-r24869] Description:Quincey Koziol2014-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Clean up more compiler warnings, plus merge a few Coverity bug fixes from the hdf5_1_8_coverity branch back to the trunk: r20877: Purpose: Fix coverity issue 1723 Description: Modified test_generate in hl/test_image to close file "f" before exit, even if an error occurs. r20879: Issue 63: change check of return of H5Tget_nmembers to <=0. No need to go futher if call fails as well as empty. r20881: Coverity #659 in Run 46: I changed the Line 442 where it tries to check whether FLAG_PRINTED is TRUE. But it had just been set to FALSE. I took out the condition check in the print statement. Tested on: Mac OSX/64 10.9.2 (amazon) w/C++, FORTRAN & Parallel (too minor to require h5committest)

* [svn-r21919] Description:Quincey Koziol2012-02-091-2/+2
| | | | | | | | Refactor function name macros and simplify the FUNC_ENTER macros, to clear away the cruft and prepare for further cleanups. Tested on: Mac OSX/64 10.7.3 (amazon) w/debug, production & parallel
* [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-r14376] moved a couple more private filter symbols to the public side, ↵Pedro Vicente Nunes2008-01-041-1/+0

| | | | | | | | | | | | | | | | | | | | Make H5Pget_filter_by_id() API versioned and switch internal usage to H5Pget_filter_by_id2(). Add simple regression test for H5Pget_filter_by_id1(). Tested on: FreeBSD/32 6.2 (duty) in debug mode FreeBSD/64 6.2 (liberty) w/C++ & FORTRAN, in debug mode Linux/32 2.6 (kagiso) w/PGI compilers, w/C++ & FORTRAN, w/threadsafe, in debug mode Linux/64-amd64 2.6 (smirom) w/default API=1.6.x, w/C++ & FORTRAN, in production mode Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN, in production mode Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN, w/szip filter, in production mode Mac OS X/32 10.4.10 (amazon) in debug mode
* [svn-r13253] Updated all C and C++ style source code files with the THG ↵Albert Cheng2007-02-071-2/+3
| | | | | | | | | copyright notice. Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.
* [svn-r11245] Purpose:Quincey Koziol2005-08-131-4/+4
| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r10703] Purpose:Quincey Koziol2005-04-301-6/+6
| | | | | | | | | | | | | | | | Bug fix Description: Correct bug where buffers that have only fractional elements (usually from being compressed before being shuffled) would cause optimized algorithm to dump core. Solution: Don't attempt to shuffle bytes unless we've got more than one element. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r10628] Purpose:Quincey Koziol2005-04-181-1/+4
| | | | | | | | | | | Code cleanup Description: Clean up various warnings reported by the Windows team. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest

| | | | | | | | | | | Code optimization Description: Use Duff's Device to unroll shuffling loop a bit, for ~30% speedup. Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti)
* [svn-r9857] Purpose: MaintenanceElena Pourmal2005-01-221-3/+0
| | | | | | | | | | | | | | Description: Removed PABLO from the source Solution: Platforms tested: arabica with 64-bit, copper with parallel, heping with GNU C and C++ and PGI fortran (but I disabled hl, there is some weird problem only on heping: F9XMODFLAG is not propagated to the Makefile files Misc. update:
* [svn-r8781] James Laird2004-07-011-0/+7
| | | | | | | | | | | | | | | | 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-r8218] Purpose:Pedro Vicente Nunes2004-02-231-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | bug fix in H5Zshuffle.c add more tests to h5repack that exposed the bug Description: when creating a dataset with the shuffle filter and duplicating it in a new dataset (file) the call to H5Z_set_local_shuffle failed. this is because the value of cd_nelmts of the filter structure is set to 1 (H5Z_SHUFFLE_TOTAL_NPARMS) when the original dataset is created, but when the new dataset is created there is a checking instruction that fails if the value of cd_nelmts is not 0 (its original value, H5Z_SHUFFLE_USER_NPARMS) Solution: just remove that check condition, since the value of cd_nelmts is not used anyway. if we decide that the value of cd_nelmts is necessary, then the H5O_pline_copy function must be changed to update this value (a different update for each filter) Platforms tested: linux solaris AIX Misc. update:
* [svn-r7384] Purpose:Quincey Koziol2003-08-191-1/+2
| | | | | | | | | | | Code cleanup Description: More linting... Platforms tested: FreeBSD 4.8 (sleipnir) too minor to need h5committest
* [svn-r7237] Purpose:Quincey Koziol2003-07-171-1/+4
| | | | | | | | | | | Code cleanup Description: Move PABLO_MASK above including headers. Platforms tested: FreeBSD 4.8 (sleipnir) too minor for h5committest

* [svn-r6611] Purpose:Quincey Koziol2003-04-091-4/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r6578] Purpose:Quincey Koziol2003-04-031-12/+10
| | | | | | | | | | | | | | | | Code cleanup Description: Added lots of comments to existing filters, so they are easier to understand and use as examples for future filters. Cleaned up various bits of code, etc. Solution: Platforms tested: FreeBSD 4.8 (sleipnir) IRIX64 6.5 (modi4) w/parallel Misc. update:
* [svn-r6546] Purpose:Bill Wendling2003-03-311-3/+14

* [svn-r6411] Purpose:Quincey Koziol2003-02-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Code Cleanup & New Feature Description: H5config.h.in: Removed H5_HAVE_COMPRESSION & H5_HAVE_FILTER_GZIP flags. Added H5_HAVE_FILTER_DEFLATE flag. H5Z.c: H5Zprivate.h: H5Zpublic.h: Switched from using H5_HAVE_COMPRESSION flag in favor of H5_HAVE_FILTER_DEFLATE. Added H5Zunregister & H5Zfilter_avail API functions. Changed a numeric constant (256) to a symbolic constant (H5Z_FILTER_RESERVED). Automatically add the shuffling filter to the list of available filters (when it is enabled). Moved prototypes for H5Z_filter_deflate & H5Z_filter_shuffle from the public header into the private header. H5Zdeflate.c: Switched from using H5_HAVE_COMPRESSION & H5_HAVE_FILTER_GZIP flags in favor of H5_HAVE_FILTER_DEFLATE. Cleaned up formatting & error reporting a bit. H5Zshuffle.c: Rewrote shuffling algorithm to be more efficient. Added error checking & reporting. Added standard Pablo information. Added standard function header comment. Added FUNC_ENTER & FUNC_LEAVE macros. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir)
* [svn-r6087] MuQun Yang2002-11-131-0/+81
Purpose: Adding internal shuffle filter Description: With the combination of shuffling filter with general compression algorithm, the compression ratio may be improved without adding much encoding and decoding time for many real NASA datasets(especially floating data) and other application datasets(See techNotes). Solution: SHuffle the bytes within the data to utilize the locality. Platforms tested: arabica , eirene, modi4 Misc. update: Update MANIFEST if you add or remove any file. Update release_docs/RELEASE for bug fixes, new features, etc. Update applicable document files too.
