* [svn-r9758] Purpose:MuQun Yang2005-01-061-0/+1
| | | | | | | | | | | | | | | | | Adding framework of N-bit filter Description: N-bit filter is required for NetCDF project. To add N-bit filter, configure.in configure, Makefile.in under src and other filter-related source code needs to be updated. Currently, N-bit tests are turned off from the library. So the change will affect daily test. Solution: Platforms tested: sol 2.7, linux 2.4, aix 5.1 Misc. update:
* [svn-r8781] James Laird2004-07-011-2/+12
| | | | | | | | | | | | | | | | 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-r8150] Purpose:Pedro Vicente Nunes2004-02-041-0/+1

* [svn-r7181] Purpose:Quincey Koziol2003-07-071-5/+0
| | | | | | | | | | | Version update Description: Removed 1.4 compatibility code in the library. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7126] Purpose:Quincey Koziol2003-06-301-2/+4
| | | | | | | | | | | | | 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-r6611] Purpose:Quincey Koziol2003-04-091-4/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r6551] Purpose:MuQun Yang2003-04-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support szip compression in HDF5 Description: szip compression support is required by NASA ESDIS. The compression algorithm is good for scientific data. In HDF5, we add another filter function to make szip as a default compression package as we did for gzip(or zlib). In this check-in, a new function called H5Pset_szip was added into H5Pdcpl.c, this function is very similar to H5Pset_deflate. The only difference is SZIP needs four parameters from the user to get the compression done while gzip needs only one. So we pass a pointer to this function instead of an integer number. The description of the four parameters of szip should be in different documents. H5Z.c and other header files were simply modified to have HDF5 know szip. Solution: See the decription 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 cause any real problems. Misc. update:
* [svn-r6415] Purpose:Quincey Koziol2003-02-181-5/+17
| | | | | | | | | | | | | Code cleanup Description: Changed hard-coded magic number (32) for the maximum number of filters in a filter pipeline to use a symbolic constant (H5Z_MAX_NFILTERS) instead. This limit could (and probably should) be removed to allow an unlimited number of filters in a pipeline. Platforms tested: FreeBSD 4.7 (sleipnir)
* [svn-r6400] Raymond Lu2003-02-121-1/+1
| | | | | | | | | | | Purpose: Change feature Description: Switch to Fletcher32 from Adler32 checksum Platforms tested: arabica, eirene, modi4 Misc. update: MANIFEST and RELEASE.txt updated.
* [svn-r6375] Raymond Lu2003-02-041-1/+30
| | | | | | | | | | | Purpose: New feature Description: Added Adler32 checksum as a filter in pipeline Platforms tested: arabica (fortran), eirene (, C++), modi4 (parallel, fortran) Misc. update: Update release_docs/RELEASE.
* [svn-r6269] Purpose:Quincey Koziol2003-01-131-4/+4
| | | | | | | | | | | | | Code cleanup Description: Various code cleanups to allow the development branch to be compiled with a C++ compiler (i.e. CC=g++ ) Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) C++
* [svn-r6114] Purpose:Quincey Koziol2002-11-201-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/+4
| | | | | | | | | | | | | | | | | | | 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.
* [svn-r5931] MuQun Yang2002-09-201-1/+1
| | | | | | | | | | | | Purpose: __DLL__ is a keyword in some platforms and __DLL__ is also defined as a macro for windows DLL applications. That causes problems. Description: Solution: Use H5_DLL*** to replace __DLL***__ at all header files. Change the macro defination at H5api_adpt.h. Platforms tested: linux2.2.18smp, irix64, solaris 2.7 and windows 2000
* [svn-r1619] ./src/H5O.c [1.2, 1.3]Robb Matzke1999-08-301-0/+4
| | | | | | | | | | | | | | | | Fixed a read-uninitialized-memory error that resulted in the file containing small amounts (<8 bytes each) of uninitialized data. These padding areas (which are never read by hdf5) are initialized to zero now. ./MANIFEST ./src/H5Z.c ./src/H5Zdeflate.c [NEW] ./src/H5Zprivate.h ./src/H5Zpublic.h ./src/Makefile.in The zlib filter was moved to a separate file but is still automatically defined.
* [svn-r1051] changed the HDF5DLL and HDF5GLOBAL to __DLL__ and __DLLVAR__Patrick Lu1999-02-021-1/+1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./tools/h5tools.c Strings are not converted to null-padding before being printed; they are printed with whatever byte values appear in the file. ./tools/h5ls.c Now able to display attribute data type and data. Added a `-f' or `--full' switch which causes the full name of each object to be displayed instead of just the base name. Added a `-r' or `--recursive' switch that recursively prints the contents of groups, avoiding cycles. More bulletproofing for non-printable characters in things like object names, attribute names, and comment strings. We don't want listing a file to send termal escape sequences because it's sometimes possible to execute commands that way. Since h5ls doesn't usually use quotes around object names we must sometimes escape space characters. External files are listed in a table to make the output less confusing. ./tools/h5tools.c ./tools/h5tools.h Changed h5dump() to h5dump_dset() and added h5dump_mem(). Also make h5dump_fixtype() public. ./test/dtypes.c Wrote some data to an attribute to test h5ls attribute printing. ./src/H5ACprivate.h ./src/H5Apublic.h ./src/H5Dprivate.h ./src/H5Dpublic.h ./src/H5Epublic.h ./src/H5Fprivate.h ./src/H5Fpublic.h ./src/H5Gprivate.h ./src/H5HLprivate.h ./src/H5Oprivate.h ./src/H5Ppublic.h ./src/H5RApublic.h ./src/H5Rpublic.h ./src/H5Spublic.h ./src/H5Tpkg.h ./src/H5Tpublic.h ./src/H5Vprivate.h ./src/H5Zpublic.h ./src/H5private.h ./src/H5public.h Reindented function prototypes after `HDF5API' was added. Also rewrapped long lines. ./src/H5Flow.c Added an `#ifdef WIN32' around an unused variable. ./src/H5api_adpt.h Removed extra carriage returns inserted by "broken" operating system. ./src/H5Dprivate.h ./src/H5Oprivate.h ./src/H5Vprivate.h ./src/H5private.h Removed extraneous inclusion of H5api_adpt.h since it's included in H5public.h which is included by everything. ./src/Makefile.in Added H5api_adpt.h to the list of public header files to fix broken `make install'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./html/Datasets.html Fixed a couple of typos. ./src/H5.c Added the `Z' modifier to HDfprintf() for `size_t' sizes. Use it like this: HDfprintf(stderr,"size is %Zd\n", (size_t)x); ./src/H5AC.c ./src/H5F.c ./src/H5Fprivate.h The maximum number of meta data objects that can be cached can be set from the application (but the library might not honor it every time; it's a hint). ./src/H5D.c Changed a warning message so it's not so alarming. ./src/H5Fistore.c Chunks can be cached. ./src/H5O.c ./src/H5Oprivate.h Added H5O_copy() and H5O_free() to copy and free messages. ./src/H5P.c ./src/H5Ppublic.h Added H5Pset_cache() and H5Pget_cache() and changed lots of "template" to "property list". ./src/H5Z.c ./src/H5Zpublic.h Miscellaneous little things to clean up. Mostly just removed H5Z_MAXVAL and added H5Z_USERDEF_MIN and H5Z_USERDEF_MAX. ./MANIFEST ./test/Makefile.in ./test/chunk.c [NEW] Added a performance test for chunk caching. It looks at the amount of I/O instead of timing because timing is partly dependent on the chunk size and I wanted a measurement that was a function of only the cache size. Run `chunk' with no arguments and then say `gnuplot x-gnuplot' to see the plots (press return between plots). Postscript files are created for each plot. ./test/big.c ./test/cmpd_dset.c ./test/extend.c ./test/external.c ./test/gheap.c Added H5F_ACC_DEBUG so we can see cache performance statistics.

---------------------- ./html/Compression.html [NEW] ./html/Datasets.html ./html/H5.format.html ./html/H5.user.html Documented compression. A couple of the H5P functions aren't quite implemented yet but they're coming soon... ./src/H5Dprivate.h ./src/H5E.c ./src/H5Epublic.h ./src/H5Farray.c ./src/H5Fistore.c ./src/H5Fprivate.h ./src/H5MF.c ./src/H5MFprivate.h ./src/H5O.c ./src/H5Ocomp.c [NEW] ./src/H5Oprivate.h ./src/H5P.c ./src/H5Ppublic.h ./src/H5Sprivate.h ./src/H5Ssimp.c ./src/H5Z.c [NEW] ./src/H5Zprivate.h [NEW] ./src/H5Zpublic.h [NEW] ./src/Makefile.in ./src/hdf5.h ./test/dsets.c ./test/istore.c Compression is now mostly working. Don't try to open a compressed dataset though because the compression message won't be read. ./html/Datatypes.html ./html/H5.api.html ./src/H5.c ./src/H5private.h ./src/H5D.c ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h Added timing support. When compiled with H5T_DEBUG defined the library will print conversion bandwidths when the library closes. The H5Tregister functions take a string as the first argument so the statistics output is meaningful. ./MANIFEST Added new files. ./configure.in ./src/H5config.h.in Check for getrusage(). Check for compress2() in libz.a and the zlib.h header file. Added `z' to the debug list. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c ./src/debug.c Cleaned up some indentation and added support to print istore B-trees. From the debugger, give the B-tree address and the dimensionality from the layout message of the object header. ./src/h5ls.c The oid is printed as w:x:y:z where w and x are the file ID and y and z are the OID within the file. You can give z or y*2^32+z as an argument to the debugger to print the object header for the object. ./src/H5AC.c Cleaned up statistics and made them match those reported by H5T and H5Z. ./src/H5MM.c ./src/H5MMprivate.h ./src/H5Fistore.c Finally got rid of a couple of long-standing const cast warnings.
