* [svn-r8009] Purpose:Quincey Koziol2003-12-311-0/+10
| | | | | | | | | | | | | | | | | Bug fix Description: Add special-case handling to floating-point conversion tests to avoid problems with denormalized values on Cray T3E & T90 platforms. (Still not working on Cray SV1, but at least it's closer). Solution: Detect denormalized values and don't try to operate on them on the Crays. Platforms tested: FreeBSD 4.9 (sleipnir) Cray T3E (hubble.cray.com) Cray T90 (gypsy.cray.com)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Omnibus floating-point bug fix changes Description: There are a number of problems in the floating-point conversion code that were exposed by Ray's recent int<->float checkin: - The 'my_isnan' code in test/dtypes.c was broken and would always return true. The meant that the actual values in the float<->float conversion tests were _never_ checked, hiding the other bugs included in this checkin. - A recent change I made to the type conversion code used "FLT_MIN" instead of "-FLT_MAX" for the most negative 'float' value for the double->float conversion, which meant that any the negative number that was converted from a double to a float would have been mapped to zero, essentially. - A change that Robb appeared to have made ~2.5 years ago to the "generic" float->float conversion routine appears to be incorrect and I've backed it out. - Floating-point conversions on SGI's which converted denormalized values would be mapped to zero instead of being propertly preserved in the new type. This was addressed by an SGI-specific system call to prevent the behavior. Solution: Described above, generally. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest Misc. update: release_docs/RELEASE update forthcoming...
* [svn-r7829] Purpose:Quincey Koziol2003-11-081-4/+0
| | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Allowing the library to call malloc with a size of 0 bytes causes problems for some users, so we check for allocations of 0 bytes and disallow them now. Cleaned up some code which could call malloc with 0 size. Changed some code calling HDmalloc directly to call H5MM_malloc(), which allows us to check for 0 sized allocations. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7482] Purpose:Quincey Koziol2003-09-161-1/+2
| | | | | | | | | | | | | | | | | Bug fix Description: The MPI_File_set_size() routine on ASCI Red is not able to extend files so that they are larger than 2GB. Solution: Add an extra macro which controls whether MPI_File_set_size() can handle >2GB offsets or if our "older" way of reading a byte, then writing a byte at the appropriate offset should be used. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest

* [svn-r7367] Purpose:Bill Wendling2003-08-151-0/+3
| | | | | | | | | | | | | | | | | | | Update Description: Added an extra flag to the clear functions that triggers a "destroy" of the object being cleared if necessary. This is a fix for the FPHDF5 stuff which had an object sticking around after it was cleared. (In FPHDF5, some processes are in charge of destroying the object, but all processes might actually allocate the object.) Platforms tested: AIX (Copper: Fortran & C++) Linux (Verbena: Fortran & C++) IRIX (Modi4: Parallel & Fortran) (Sol is down) Misc. update:
* [svn-r7269] Purpose:Bill Wendling2003-07-281-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Update Description: Revamped the configuration system. The configurations for the Fortran and C++ libraries are no longer separate from the "main" configuration system. This involved removing the "configure*" and "aclocal.m4" files from the fortran/ and c++/ subdirectories. Also merging settings in the config/ subdirectories into the main config/ subdirectory. Fortran header files had to be modified a little for Linux. It was checking if it was a Linux machine by some #defines, however with the -std=c99 switch, these defines weren't there. I added a check for some other ones which should be there whether the -std=c99 switch is used or not. Platforms tested: Verbena (Fortran & C++) Sol (Fortran & C++) Copper (Fortran & C++) Modi4 (Parallel, Fortran, & C++) Misc. update:
* [svn-r7181] Purpose:Quincey Koziol2003-07-071-2/+8

* [svn-r6797] Purpose:Bill Wendling2003-05-051-3/+3
| | | | | | | | | | | | | | | Feature Description: Added new flag to the H5pubconf.h file --- NO_SHARED_WRITING (H5_NO_SHARED_WRITING). It's only defined for CodeWarrior and should never be defined for other platforms unless the "open()" bug that CW has shows up on other platforms. Platforms tested: Verbena. Configure only, so no need for full tests. Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | To support szip compression in HDF5 Description: szip compression support is required by NASA ESDIS. The compression algorithm is a good compression algorithm 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). H5config.in needs to be regenerated by autoheader for SZIP flags. Solution: A new file called H5Zszip.c will be added in the Makefile.in Flags like: HAVE_FILTER_SZIP should be auto-generated by autoheader. 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:

| | | | | | | | | | | Purpose: Change feature Description: Switch to Fletcher32 from Adler32 checksum Platforms tested: arabica, eirene, modi4 Misc. update: MANIFEST and RELEASE.txt updated.
* [svn-r6386] Purpose:Quincey Koziol2003-02-101-0/+4
| | | | | | | | | | | | | | Bug fix Description: The "system scope" for threads isn't supported on all platforms. Solution: Add detection of this feature to the configure script and check for "H5_HAVE_SYSTEM_SCOPE_THREADS" in the appropriate places. Platforms tested: modi4 w/threadsafe
* [svn-r6383] Purpose:Quincey Koziol2003-02-071-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature for developers. Description: Added "function stack" tracing to library. This allows developers (there is no public API) to call H5FS_print within the library and get a listing of the functions traversed to reach that point in the library. Eventually, I may add support for reporting the parameters to each function also... Mainly for debugging parallel I/O programs, but I think it will come in handy in other cases also. The function stack tracking is controlled with a configure switch: --enable-funcstack, which defaults to enabled currently. When we branch for 1.6, we should change the default setting on the branch to be disabled. Also, added a destructor to the thread-specific keys when thread-safety is turned on in the library. Otherwise, they were leaking memory and causing difficult to debug errors in threaded programs (like the test/ttsafe test). Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) w/thread-safety enabled. Misc. update: Updated MANIFEST with new files added (src/H5FS.c & src/H5FDprivate.h) Update release_docs/RELEASE with thread-safety bug fix.

* [svn-r6302] Added the testing of libmpe.Albert Cheng2003-01-181-0/+3
| | | | | | | | This is generated by autoheader. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}? YES Other platforms/configurations tested? eirene with --enable-mpe
* [svn-r6232] Purpose:Albert Cheng2003-01-031-0/+3
| | | | | | | | | | | | | | | | new feature Description: Added MPICH/MPE instrumentation support. All source code are bracketed by the macro H5_HAVE_MPE. Use "--enable-mpe" to configure it in. Currently only worked in Eirene because the MPE library is not installed in all machines yet. The added file, H5MPprivate.h, holds HDF5/MPE related defintions. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}? Yep. Other platforms/configurations tested? --enable-mpe feature tested in Eirene.
* [svn-r6228] Description:Albert Cheng2003-01-031-3/+0
| | | | | | | | When I removed the option (--enable-parallel=mpich), which did not work, I failed to run autoheader to update this file. I am checking in the updated version now. Platforms tested: No need to test since it just removed a #undefine and comments.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r6070] Purpose:Quincey Koziol2002-11-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | New feature. Description: Add in '--enable-filters=filter1,filter2' flag to configure script. This can also be used as '--enable-filters=all' or just '--enable-filters' to enable all the internal I/O filters in the library. This flag can also be set to '--disable-filters' to disable all the internal I/O filters. Individual filters can not be disabled due to the limitations of autoconf. Additionally, added "H5_HAVE_FILTER_<foo>" macros to H5pubconf.h header file, so the presence of each filter can be detected. This is in preparation for Kent's shuffling filter to be imported shortly. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Tested FreeBSD 4.7 (sleipnir) also
* [svn-r6026] Purpose:Bill Wendling2002-10-231-0/+3
| | | | | | | | | Feature Add Description: New Makefiles and H5config.h.in file for the Flexible Parallel HDF5 stuff. Platforms tested: Eirene, Arabica, Modi4
* [svn-r5807] Purpose:Bill Wendling2002-07-171-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | Update, Bug Fix, and Feature Add Description: - Updated how AC_{ENABLE,WITH} help messages were being generated. Autoconf now gives you an AC_HELP_STRING macro to use to create them. - Fixed the problem with Linux LFS on RedHat 7.3 machines. It wasn't finding getdents64(), so we can't rely on that being present anymore... - Added GPFS detection and setting. - Updated how compression is specified. It's no longer necessary to test for HAVE_ZLIB_H, HAVE_LIBZ, and HAVE_COMPRESS2. The one macro {H5_}HAVE_COMPRESSION takes care of all of these. Solution: Changed the check for Linux LFS from looking for getdents() to looking at the version number of the kernel (using the uname -r command). You can still override with the --enable-linux-lfs switch if you really believe that your <2.4 kernel has LFS support. Platforms tested: Linux (2.2 and 2.4)
* [svn-r5782] Purpose:Quincey Koziol2002-07-121-3/+6
| | | | | | | | | | | New feature Description: Add support in for "dmalloc" debugging malloc library to configure script and library headers. Platforms tested: IRIX64 6.5 (modi4) and FreeBSD 4.6 (sleipnir)

This is absolute important. Test it out on at least two or three different platforms such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and 64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.]
* [svn-r5132] Purpose:Bill Wendling2002-04-021-279/+324
| | | | | | | | | | | | | | | | | | | Autotools Update Description: I've updated autoconf, automake, and libtool to the latest/greatest versions; 2.53, 1.6, and 1.4.2 resp. Many changes come with the new versions: - ltconfig is no longer used - acconfig.h is no longer used (#define values are declared with the macro) - regeneration of all of the aclocal.m4, configure, and H5config.h.in files. - new config.{guess,sub} files - new ltmain.sh file Platforms tested: AIX (blue), and Linux
* [svn-r5074] Purpose:Bill Wendling2002-03-201-15/+4
| | | | | | | | | Code Motion Description: Removal of HDF4 from the configure/Makefiles. This is a precursor to the actual physical removal of the HDF4 tools from the HDF5 tree. Platforms tested: Arabica, Dangermouse
* [svn-r4840] Purpose:Quincey Koziol2002-01-161-0/+3
| | | | | | | | | | New feature check Description: Added check to determine if malloc(0) returns a valid pointer for a particular architecture. Platforms tested: FreeBSD 4.5 (sleipnir) where malloc(0) works Cray SV1 (killeen) where malloc(0) doesn't work
* [svn-r4763] Bill Wendling2002-01-021-21/+6
| | | | | | | | | | | | Purpose: Feature Add Description: Needed to add the DEV_T_IS_SCALAR macro to acconfig.h so that autoheader will propagate that to the H5config.h file. Solution: Added, reran autoheader Platforms tested: Linux
* [svn-r4312] Purpose:Quincey Koziol2001-08-061-2/+2
| | | | | | | | | Feature shift Description: Take out the v1.2.x compatibility stubs and put in the hooks for v1.4.x compatibility when needed. Platforms tested: FreeBSD 4.3 (hawkwind)
* [svn-r4232] Purpose:Quincey Koziol2001-07-171-0/+3
| | | | | | | | | | | | | | | | | Bug fix. Description: On some systems (linux when not using gcc) 'dev_t' is not actually a scalar variable. This causes the code which compares dev_t's in the file drivers to not compile. Also the H5_inline flag was not being set correctly in the H5private.h file. Solution: Set the H5_inline flag to '' (i.e. define it, but don't assign it a value) if it is not currently defined. Use DEV_T_IS_SCALAR flag from configure to correctly compare dev_t's using memcmp instead of a scalar flag. Platforms tested: FreeBSD 4.3 (hawkwind), Linux 2.4.2 (chiba city cluster at Argonne)
* [svn-r4017] Purpose:Quincey Koziol2001-06-191-0/+6
| | | | | | | | | | | | | Code cleanup Description: Several system header files needed to be included on Linux machines to get the prototypes for some of the system calls we are using. Solution: Added a new feature test macro for including the <features.h> header on Linux machines, to set up compile macros for system header files. Platforms tested: Linux (eirene), FreeBSD 4.3 (hawkwind)
* [svn-r3892] Purpose:Bill Wendling2001-05-081-0/+3
| | | | | | | | | | | | | | | | | Better Mouse Trap^W^WBug Fix Description: Instead of having the large file support stuff be in the config/gnu-flags directory, I added it to the configure.in file so that it first checks for the syscall ``getdents64()''. If it finds it, then it removes the ``-malign-double'' flag if the GCC compiler is 2.95.x since this flag doesn't play well with the LFS stuff. Solution: Added test for getdents64(), if found it removes the -malign-double flag if the compiler is 2.95.x. This is done in the configure.in file. The gnu-flags file is returned to normal. A new field is added to the H5config.h.in file because of the getdents64 check. Platforms tested: Linux
* [svn-r3742] Purpose:Quincey Koziol2001-04-011-0/+3
| | | | | | | | | | | Code cleanup Description: ssize_t is not defined on certain (non-UNIX) platforms. Solution: Added steps to configure to generate SIZEOF_SSIZE_T macro and then used the new macro to define ssize_t for platforms which don't have it. Platforms tested: FreeBSD 4.3 (hawkwind)

* [svn-r3252] Purpose:Quincey Koziol2001-01-091-0/+3
| | | | | | | | | | | | | Code cleanup. Description: Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the extra warnings. Including a few show-stoppers for compression on IRIX machines. Solution: Changed lots of variables' types to more sensible and consistent types, more range-checking, more variable typecasts, etc. Platforms tested: FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)
* [svn-r3058] Thomas Radke2000-12-011-0/+3

* [svn-r2886] Purpose:Quincey Koziol2000-11-131-0/+3
| | | | | | | | | | Backward compatibility additions Description: Created HDF5 v1.2 compatibility API functions (H5Tget_member_dims & H5Tinsert_array) which use the newer array datatypes underneath, but should ease user's transition to the 1.4 version of the library. Platforms tested: FreeBSD 4.1.1 (hawkwind)

| | | | | | | | | | | | Purpose: Bugfix Description: Rename the [H5_]HAVE_STRUCT_SOCKLEN_T into [H5_]HAVE_SOCKLEN_T. Solution: As pointed out by Bill the socklen_t type isn't a structure if is it defined by the system headers. So we should better take out the _STRUCT_ from the defines. Platforms tested:
* [svn-r2816] Thomas Radke2000-11-081-1/+10

* [svn-r2748] Thomas Radke2000-10-281-0/+3
| | | | | | | | | | | | | Purpose: Detect whether the system has the netinet/tcp.h header file. Description: The Stream VFD uses setsockopt(2) to set TCP_NODELAY on an opened socket. This constant is defined normally in netinet/tcp.h except for GNU cc under Windows where this header doesn't exist. This template header file just contains the #undef HAVE_NETINET_TCP_H Platforms tested: Windows NT, GNU cc
