* [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.

| | | | | | | | | | | | | | | | | 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

* [svn-r8075] Purpose:Quincey Koziol2004-01-161-1/+55
| | | | | | | | | | | | | | | | | | Bug fix. Description: Fix problems in B-tree deletion routine that were corrupting the data structure when the B-tree had several levels and the right-most item from a leaf node that was the right-most child of an internal node was removed. Also address similar problems when a complete internal or right-most node was removed. NOTE: The B-tree deletion routines are still _NOT_ maintaining the B-tree properties correctly, that will be addressed in a future (hopefully soon) fix. Platforms tested: FreeBSD 4.9 (sleipnir) too obscure to require h5committest
* [svn-r8057] Purpose:Quincey Koziol2004-01-131-1/+5
| | | | | | | | | | | Bug fix Description: Plug another small memory leak for fill-values. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r8053] Purpose:Quincey Koziol2004-01-133-17/+21
| | | | | | | | | | | | | | | | | | | | Bug fix Description: Correct two problems with variable-length datatypes in datasets: - When overwriting an entire dataset, writing the fill value to the file would be skipped, causing problems for VL datatypes when objects in the file had been unlinked (and thus the space in the file was not all zeros) - When an application has set a fill-value for a dataset and the dataset's datatype contained a VL datatype, the library was filling space on disk with the memory form of the VL information, instead of the disk form. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest

* [svn-r8048] Purpose:Quincey Koziol2004-01-101-1/+1
| | | | | | | | | | | | | Code cleanup & reorganization Description: Move further in the testing framework cleanup, eliminating all the global variables (moving them into testframe.c as static variables) from the testing framework code and moving it into the libh5test.a.

* [svn-r8038] Purpose:Quincey Koziol2004-01-0819-233/+691
| | | | | | | | | | | | | | | | | | | | Bug fix Description: When two property lists are compared, the H5Pequal routine was just comparing the raw information for the property values. This causes problems when the raw information contains pointers to other information. Solution: Allow a 'compare' callback to be registered for properties, so that a user application get perform the comparison itself, allowing for "deep" compares of the property value. This was exported to the H5Pregister & H5Pinsert routines in the development branch, but not the release branch. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest

| | | | | | | | | | | | | | | Bug fix Description: Fix small memory leak of fill-value information inside the library. Solution: "reset" the fill-value object header message, so that the internal buffer gets freed. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest

| | | | | | | | | | | | | | Bug fix Description: Range check the szip 'pixels per block' against the chunk size of the dataset when attempting to create a new dataset, since the szip library requires the PPB to be at least the size of the fastest changing dimension in the chunk.

* [svn-r7978] Purpose:Albert Cheng2003-12-251-127/+61
| | | | | | | | | | | | | | | | | | | | | | | | Bug fix Description: MPIO driver did not detect partial read or write. It assumed if read completed, all bytes requested are read. Therefore, if a dataset was not completely written yet, the unread part will not be filled with default fill value. Solution: Added the MPI_Get_elements call to find exactly how many bytes are read (or written). For read case, if not enough is read, the rest is padded with zeros. For write case, it is an error if not able to write them all in first attempt. (It is not always possible to repeat write for MPIO since file-view may be changed, collective would hang, etc. So, we do just one attempt.) Platforms tested: eirene (pp). Should work for other platforms since these have been tested in v1.6. Misc. update:
