* [svn-r12019] Purpose:Leon Arber2006-03-071-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix/Feature Description: Modify the library to use rand_r, when available, instead of srand. If rand_r is not available, it will try to use srandom/random, and then finally fall back to srand/rand. Solution: A couple places in the library use the srand() function to seed the random number generator. This can cause problems on certain platforms and could theoretically cause problems for users who expect a certain sequence of random numbers following their own call to srand(). Most platforms have an implementation of rand_r, which is identical to rand, except that it allows for explicit storage of the seed value. The configure script will now check for the existence of rand_r to facilitate its use in the library. Two new functions are added, to replace the macros HDsrand/HDrand. These functions are HDrand and HDsrand. HDrand will call rand_r, if available, or random(), if available, and fall back to rand() if neither of those is available. HDsrand will store the seed value locally, if rand_r is available. Otherwise, it will call srandom if available, and fall back to srand otherwise. Platforms tested: heping, mir. Really need to test on Red Storm, since that platform motivated this fix, but the machine is currently not available. Misc. update:

| | | | | | | | | | | | | | | | | | Bug fix Description: Fixed bug in hl/src Makefile that was deleting y.tab.c. Running bin/reconfigure changed a few other files as well (somebody probably updated Makefiles.am but forgot to bin/reconfigure). Solution: Automake in its wisdom adds the line "rm *.tab.c" to every distclean in every directory. I assume that it assumes that such files are generated during the build. Supplied an empty distclean-compile target to remove this line from the Makefiles.in. Platforms tested: mir, sleipnir, shanti

| | | | | | | | | | | | | | | Bug fix Description: Some platforms complain that tcp.h is present but cannot be compiled. Solution: This is because tcp.h needs in.h to be included. Checked for netinet/in.h and included it when netinet/tcp.h is being checked. Platforms tested: mir, cu11

* [svn-r11311] Purpose: New features.Raymond Lu2005-08-291-20/+28
| | | | | | | | | | | | | | | | | | | | Description: Added 2 new configure options, --enable-exception and --enable-accuracy. --enable-exception lets the library check whether user's exception handling functions are present during compiler data conversions and use them if they are. When it's disabled, this step is skipped to improve conversion speed. This step isn't implemented yet for soft conversions because there would be little gain in speed. --enable-accuracy guarantees data accuracy during data conversions. It means the library will choose compiler conversions only if the accurate data is secured. Otherwise, the library will go for the library's own conversions. If this option is disabled, the library uses compiler conversions in favor of their speed as long as they work even if data can be incorrect. Platforms tested: h5committest and fuss. Some systems may fail after this checkin.

* [svn-r11087] Purpose: Bug fix.Raymond Lu2005-07-191-0/+4
| | | | | | | | | | | | | | Description: When converting floating-point numbers to integers and the values of floating-point number are greater than the maximal value of integer, Cray X1 generates floating exception. Solution: Added a test in configure to detect Cray X1's exception. Set a flag to indicate the machine that can handle overflow converting all floating-point to all integer types. This flag should be set for all machines, except for Cray X1 where floating exception is generated when the floating-point value is greater than the maximal integer value. Platforms tested: Cray X1 and h5committest.

| | | | | | | | | | | | | | | | Portability feature Description: The random() and srandom() functions are not available on all machines. Set up the configure script to automatically detect them, rather than requiring their presence or absence to be hardcoded. Solution: Added AC_CHECK_FUNCS macro to configure.in and replaced #ifdef WIN32 conditionals with #ifdef H5_HAVE_RANDOM conditionals. Platforms tested: sleipnir, Windows

| | | | | | | | | | | | | | | | | | | | Configuration feature Description: Different Fortran compilers mangle function names in different ways (upper case, lower case, adding underscores). To link between Fortran and C functions, we need to know what a given function's name is under a given compiler. Solution: Use autoconf's FC_WRAPPERS check to determine the Fortran naming scheme and define the FC_FUNC_ macro to name our functions (in H5f90proto.h). Removed references to our old FNAME macro, as well as flags that indicated whether function names were upper or lower case. Platforms tested: mir, pommier, modi4, copper, more

* [svn-r10081] Purpose: Some Kind of VerificationRaymond Lu2005-02-241-1/+1
| | | | | | | | | | | | | | | | | | Description: The library didn't handle incorrect hardware conversion for datatype. It simply did convert to incorrect data if any hardware didn't handle correctly. Solution: During configuration, incorrect hardware conversion is detected and some macros are defined. Use these macros to decide whether to register hardware conversion in H5T.c. If no hardware conversion function is registered for certain pair of datatypes, software conversion function will be used as the conversion path. Although slower than hardware conversion, we're more confident software conversion is accurate. So in one sentence to describe library's behavior, if some hardware conversion doesn't work well, software conversion will be used instead. Platforms tested: h5committest and fuss. Misc. update: some changes to configure's comments.

| | | | | | | | | | | | | | | | | | | | Bug fix Description: Add detect vasprintf() routine and use it instead of vsnprintf() when formatting error descriptions if it's available. Added configure test to detect "broken" vsnprintf() implementations which don't return the correct number of character for strings that are too long to fit into the buffer provided (currently a problem on the SGIs and probably the HP). Re-wrote error formatting code in H5Epush_stack() to handle broken vsnprintf() implementations, etc. Platforms tested: IRIX64 6.5 (modi4) h5committest

* [svn-r9807] Purpose: bug fixRaymond Lu2005-01-111-0/+4
| | | | | | | | | | | Description: For FreeBSD (sleipnir), when GNU compilers do conversion from unsigned long long to long double, the last 2 bytes of mantissa are lost. The impact of precision loss isn't significant. Solution: Detect this case on FreeBSD in configure, ignore it in dtypes.c test instead of return failure. Platforms tested: sleipnir, fuss, modi4. These systems are mainly concerned.

| | | | | | | | | | Description: For HP-UX 11.00, the compiler generates 'floating exception' when converting 'long double' to most of integer types. Solution: Define a macro for all other systems except HP-UX 11.00. Hard set this macro to 'no' in config/hpux11.00 to skip this test for HP-UX 11.00. Platforms tested: modi4, kelgia, fuss

| | | | | | | | | | | | | | | | | 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:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes". Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel & fphdf5 FreeBSD 4.10 (sleipnir) w/threadsafe FreeBSD 4.10 (sleipnir) w/backward compatibility Solaris 2.7 (arabica) w/"purify options" Solaris 2.8 (sol) w/FORTRAN & C++ AIX 5.x (copper) w/parallel & FORTRAN IRIX64 6.5 (modi4) w/FORTRAN Linux 2.4 (heping) w/FORTRAN & C++ Misc. update:

* [svn-r8938] James Laird2004-07-231-0/+3
| | | | | | | | | | | | | | | | | | | 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-r8932] Purpose:Quincey Koziol2004-07-221-0/+4
| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up collective chunking code a bit. Also, add '--enable-instrument' configure flag to have a mechanism for determining that optimized operations happened correctly in the library (instead of just the "normal" way) by allowing 'flag' properties to be set outside the library and set when the "right" thing happens. This is mainly for debugging and regression checks, so we make certain we don't break optimized I/O by accident. It's enabled by default when --enable-debug is on (which is on by default in the development branch and off by default in the release branch), but can also be independently controlled with its own configure flag. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel IBM p690 (copper) w/parallel

| | | | | | | | | | | | | | | | 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.

* [svn-r8427] Purpose:Quincey Koziol2004-04-281-0/+4
| | | | | | | | | | | | | | | | Bug fix (sorta) Description: Add hack to allow the MS Visual Studio 6 compiler to build the library. It cannot cast unsigned long long values to float or double values. So, add another configuration macro to disable this conversion in the library. Just the "hardware" conversion is disabled, so the library will still correctly convert unsigned long long to float and double values, it will just happen more slowly with the "software" conversion routine. Platforms tested: FreeBSD 4.9 (sleipnir) with "Windows" setting faked inappropriate for h5committest

| | | | | | | | | | | | | | | Bug fix (sorta) Description: The SGI machines have problems accurately (and consistently) converting unsigned long values to float and double values, so put in a bit of a hack in the datatype conversion test code to allow them to get "close enough". This hack is enabled at configure time by a flag which should only be set on machines with this problem. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest

| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
