* [svn-r8272] Purpose:Albert Cheng2004-03-231-2/+1
| | | | | | | | | | | | | | | | bug fix. Description: H5FD_mpio_init was calling the public API version of H5Iget_type() which would clear the error stack, thus cleared away error messages prematurely. Solution: Changed it to call the private version of H5I_get_type() which does not clear the error stack. Platforms tested: o2 (SGI) parallel.

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

| | | | | | | | | | | | | Bug fix. Description: The -g in H5detect somehow does not work with 64bit mpicc in arabica. Remove it for now for better solution. Platforms tested: no test as the change is trivia. Misc. update:
* [svn-r8207] Purpose:Albert Cheng2004-02-171-1/+5
| | | | | | | | | | | | | | | | | | | | Bug fix, sort of. Description: Some compilers, e.g., intel compiler, would take a long time to compiler H5detect.c if optimization is on. Solution: Setup special make rules for H5detect to be compiled always with optimization off by using -g. Since H5detect is run once to generate H5Tinit.c, it does not matter that much if it is optimized or not. Platforms tested: "h5committested". Tested in Titan too.
* [svn-r8158] Purpose:Quincey Koziol2004-02-0616-563/+623
| | | | | | | | | | | | | | | | | Code cleanup/optimization Description: Query property list values once, at the beginning of the I/O routines, instead of querying the property list values multiple (lots!) of times in lower level routines. Solution: Create "property list caches" for internal library queries of the property list values. Platforms tested: IBM p690 (copper) w/parallel & fphdf5 h5committest
* [svn-r8157] Purpose:Quincey Koziol2004-02-064-49/+82
| | | | | | | | | | | | Code cleanup/optimization Description: Hoist property list queries up out of inner loops to cache the values at a higher level and pass them into the lower-level routines. Platforms tested: IBM p690 (copper) w/parallel & fphdf5 h5committest

* [svn-r8144] Purpose:Quincey Koziol2004-02-021-64/+18
| | | | | | | | | | | | | | | | | | | | | | | | Bug fix. Description: Revert the optimization to the MPI-I/O VFD from earlier this week that eliminated calling MPI_File_set_size() when a file was truncated. This doesn't work because of the way we track the 'eoa' (end of allocated space) in the file: we just advance the eoa value when space is allocated in the file and we don't zero out the space in the file. This causes a problem where we assume that all "newly allocated" space in the file contains zero bytes, but if we don't call MPI_File_set_size(), the file can contain the previous data (if the file previously existed) and not zeros. Unfortunately, because we allow independent raw data parallel I/O, there is no way to address this issue. :-( Solution: Revert to previous method of retrieving the file's size, etc. from before the optimization. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel too minor to require h5committest.

| | | | | | | | | | | | | | | | Code cleanup Description: Add destructor to match constructor fr VFLs when they are shut down by the library.

| | | | | | | | | | | | Bug fix Description: Include the private H5FD header instead of the public one, to address a failure in building the library with C++ compiler. Platforms tested: FreeBSD 4.9 (sleipnit) w/CC=g++ not appropriate for h5committest

* [svn-r8126] Purpose:Quincey Koziol2004-01-3128-1180/+1130
| | | | | | | | | | | | | | | | | Bug fix/optimization Description: Address slowdown in MPI-I/O file metadata operations that was introduced mid-stream. We now _require_ a POSIX compliant parallel file system for the MPI-I/O file driver (as well as for the MPI-POSIX file driver). Also optimized file open operation when the file is being created by reducing the number of collective & syncronizing calls. Additionally, refactor the MPI routines into a common place, eliminating duplicated code. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel h5committest
