* [svn-r7607] Purpose:Quincey Koziol2003-10-131-0/+1
| | | | | | | | | | Bug fix Description: Add MPE "color" for new H5Fget_freespace() API function. Platforms tested: None - just eyeballed - too minor to require testing.

* [svn-r7595] Purpose:Quincey Koziol2003-10-101-9/+11
| | | | | | | | | | | | | | | | | | | | | Bug fix Description: The 'char *' type is one of the "strongly" aligned types on Crays, but a 'void *' is "weakly" aligned. So, assigning a 'void *' (pointing to a location to place a 'char *') to a 'char **' can change the pointer value during the assignment. Solution: Don't alias the 'void *' where the variable-length information ('char *' or 'hvl_t') will go. Use a temporary variable on the stack to build up the information about the VL string or sequence and then memcpy() the temporary variable directly to the location pointed to with the 'void *' Platforms tested: FreeBSD 4.9 (sleipnir) Cray SV1 (wind) specific to Cray problems, h5committest not necessary.
* [svn-r7591] Purpose:Quincey Koziol2003-10-101-3/+1
| | | | | | | | | | | | Bug fix Description: Correct the size of the buffer needed for the destination value to use the actual destination type size. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7580] Purpose:Quincey Koziol2003-10-091-10/+13
| | | | | | | | | | | | | | | | | Bug fix Description: The VL type conversion routine attempt to align it's destination buffer to an offer that will work for both hvl_t and char * types, but the algorithm used fails to work correctly on Cray machines. Solution: Give up on attempting to align the buffer when it's allocated on the stack. Just dynamically allocate it instead. Platforms tested: FreeBSD 4.9 (sleipnir) Cray SV1 (wind)
* [svn-r7572] Purpose:Quincey Koziol2003-10-081-30/+35
| | | | | | | | | | | | | | | | | Bug fix Description: When too many messages were inserted into an object header, the library had an internal pointer to the "new message" that was pointing to the incorrect location when the array of messages was re-allocated. In the worst case, this could cause a file to be corrupted. Solution: Update the internal pointer when the array is re-allocated. Platforms tested: FreeBSD 4.9 (sleipnir) Too small to require h5committest
* [svn-r7561] Purpose:Quincey Koziol2003-10-075-2/+76
| | | | | | | | | | | | Feature add Description: Add a few new fields to the H5G_stat_t structure, to allow more information about the object header to be retrieved. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7559] Purpose:Quincey Koziol2003-10-074-0/+88
| | | | | | | | | | | | | | Add feature Description: Add H5Fget_freespace() routine, to check the amount of free space in a file. This information is only valid until the file is closed currently, however (until we start recording the free space information in the file itself). Platforms tested: FreeBSD 4.9 (sleipnir) h5committest

* [svn-r7553] Purpose:Quincey Koziol2003-10-061-79/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | Improved algorithm (bug fix, sorta) Description: The internal algorithm for adding new IDs in the ID manager code (H5I) was adding new IDs to the front of the linked list and never adjusting the order of the items on the list (unless an ID was deleted). If many new objects were created, they would push earlier ones _way_ down the list (especially if the objects were being leaked in the application, as they appear to be in the current HDF-EOS5 library) and would cause O(n) search time for items on the list. The ID caching code in the ID manager was avoiding this behavior sometimes, but it was adding IDs that were looked up to the very tail of the cache and they would frequently leave the cache before helping. Solution: Implemented a "move to front" scheme for the linked list of IDs, which improves the lookup situation for frequently accessed objects. Removed ID caching code now, as the "move to front" algorithm actually works better. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7551] Purpose:Quincey Koziol2003-10-061-8/+0
| | | | | | | | | | | | | | | Bug/feature fix. Description: Relax restriction on parallel writing to compact datasets to allow partial I/O. Updates to reference manual mentioning the issues involved are delayed until reference manual 'lock' is removed later this week. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7538] Purpose:Quincey Koziol2003-10-0522-294/+919
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fixes and code cleanup Description: Lots of changes here: - Fixed bug #691 - when shared datatypes are used in attributes they are incorrectly copied into the attribute instead of referring the the named datatype in the file. This required bumping the version of the attribute message. The new version of the attribute message is only written out when a shared datatype is used in the attribute. [Also, this format change made the size of the attribute smaller.] - Added information to attribute debugging routine so that shared datatypes are displayed correctly with the h5debug tool. - Refactored the H5O* routines to extract code that was common to several routines into subroutines to call. - Added 'link' method for H5O message sub-classes, which increments the link count on shared objects when a message is created which shares them. - Corrected [unreported] bug where the link count was not being decremented on the shared object when a object header message with a reference to that object was deleted from the file. - Reduced size of shared message from 49 bytes (which was incorrect anyway and should have been 48 bytes) to 10 bytes, which required bumping the version of "shared" messages. - Refactored some of the shared datatype routines to allow for easier queries of "committedness" internally to the library and also added routine to easily increment/decrement the reference count of a shared datatype. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7528] Purpose:Bill Wendling2003-09-301-55/+51
| | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: The FPHDF5 code couldn't create a dataset then access it. Turns out that the "O_find_in_ohdr" code was protecting the object header which pulls it into the cache then unprotecting it. However, this caused the cache entry to be blown away and THEN we'd try to reread the entry (via AC_protect) but it didn't have all of the data that the find_in_ohdr function decodes for us decoded. It was also kind of unnecessary since we can just protect then call O_find_in_ohdr. Solution: Removed the AC_protect and AC_unprotect from O_find_in_ohdr. Called AC_protect before calling the O_find_in_ohdr function. Platforms tested: Linux (Fortran, C++) IRIX (parallel, Fortran) Sun (Fortran) Misc. update:

* [svn-r7495] Purpose:Bill Wendling2003-09-194-59/+2
| | | | | | | | | | | | | | | | Removed Dead Code Description: Some of the FPHDF5 code was dead (I thought it'd be useful at one point, but was wrong). Solution: Removed Platforms tested: Linux (FPHDF5 specific. No need for h5committest) Misc. update:
* [svn-r7494] Purpose:Quincey Koziol2003-09-197-703/+792
| | | | | | | | | | | | | | | | | | Bug fix Description: Buffer for decoding superblock's driver information was too small when using some VFDs (like the multi-file VFD). Also made FPH5 code more portable and obvious when it's broadcasting the superblock from the captain process to the other clients. Solution: Allocate the buffer for the driver information dynamicly Platforms tested: Copper No h5committest because it's already working on other platforms.
* [svn-r7491] Purpose:Bill Wendling2003-09-182-115/+182
| | | | | | | | | | | | | FPHDF5 Update Description: Added locking/unlocking to the AC_protect/AC_unprotect calls. The SAP does all of the caching so nothing should be saved on the client side. So, when the client unlocks the metadata, it can destroy it. The metadata is always read from the SAP during a lock. Platforms tested: Linux (FPHDF5 specific change. No need for h5committest)
* [svn-r7489] Purpose:Bill Wendling2003-09-1823-1417/+1654
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update Description: A lot of modifications for the FPHDF5 stuff: H5AC.c H5ACprivate.h - Removed AC_find (it's replaced with AC_protect and AC_unprotect). Added flushing if it's an FPHDF5 driver and we're doing an AC_set or AC_unprotect with the dirty flag set. H5B.c - Split up the B_flush function into different functions since the one function was doing serialization which is better left as a separate entity. H5D.c - Removed some FPHDF5 code that was incorrect H5F.c - Split up the F_flush function so that it no longer allocates file space. Created new functions (F_init_superblock, F_read_superblock, and F_write_superblock) for greater modularity and so that the FPHDF5 non-captain processes can read the superblock after the captain process writes it. H5FD.c - Error message correction. H5FDfphdf5.c - Removed MPI barrier call that wasn't needed. H5FPclient.c H5FPserver.c - Modified so that if a process requests data that isn't exactly aligned, we can return it if we have the block that contains the requested address. H5G.c H5Gent.c H5Gnode.c H5HL.c H5HLpkg.h H5HLprivate.h H5Oefl.c - Removed the H5HL_peek function since it was doing a (now unsafe) holding of the information in the cache. Replaced with protect and unprotect calls. H5TB.c - Error fix. The TB_dless function wasn't working properly. H5Gstab.c - Format change. H5err.txt H5Edefin.h H5Einit.h H5Epubgen.h H5Eterm.h - Added new error code. Platforms tested: Modi4 (paralle, Fortran) Sol (Fortran) Linux (C++, Fortran) Copper (Parallel, Fortran) Misc. update:
* [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

| | | | | | | | | | | | | | | Bug fix Description: H5Dwrite was only checking the "top level" of the datatype to stop parallel I/O on variable-length datatypes. Solution: Make checks "deeper". Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7473] Purpose:Quincey Koziol2003-09-151-60/+129
| | | | | | | | | | | | | | Code cleanup & optimization Description: Split superblock initialization and space allocation out from writing the superblock information to disk, which makes the code much cleaner and easier to understand and also allows FPHDF5 to have a fully completed superblock to Bcast to other (non-caption) processes.

* [svn-r7471] Purpose:Bill Wendling2003-09-122-539/+629
| | | | | | | | | | | | | | | | | | | | | Update Description: The F_open and F_flush functions had a lot of cruft in them. The F_flush was being used as a way to allocate the superblock. The F_open had a bunch of code in there to read and serialize the superblock. Solution: Moved these out into their own functions.

* [svn-r7468] Purpose:Quincey Koziol2003-09-124-57/+161
| | | | | | | | | | | | | | | | | | Code cleanup, etc. Description: Generalize Ray's datatype fixes to handle packing compound datatypes which are the base type of an array or variable-length type, etc. Also track "packedness" of a compound datatype from it's creation, instead of only setting the 'packed' flag after the datatype was explicitly packed. Updated docs to reflect that a compound datatype is allowed to grow (but not shrink). Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7467] Purpose:Quincey Koziol2003-09-117-121/+96
| | | | | | | | | | | | | | Code cleanup Description: Patch up a few places where the metadata cache could ask for a read lock instead of a write lock and other minor code cleanups. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to need h5committest Misc. update:
* [svn-r7461] Purpose: bug #1017Raymond Lu2003-09-103-7/+16
| | | | | | | | Description: H5Tpack fails if called twice or datatype is locked. Compound datatype wasn't expandable. Platforms tested: h5committest
* [svn-r7460] Purpose:Bill Wendling2003-09-1011-61/+87
| | | | | | | | | | | | | | | Update Description: Added extra parameter to the H5AC_protect() function that indicates if the cache being asked for is going to be written to or just read from. Those AC_protect calls that were H5AC_find calls are now read-only. The rest are writes. Platforms tested: Linux (h5committest not needed due to size and small impact) Misc. update:
* [svn-r7457] Purpose:Quincey Koziol2003-09-101-25/+28
| | | | | | | | | | | | | | | | | | | | Bug fix. Description: Correct bug where a file opened twice, once with read-write permission and once with read-only permission would cause closing the file with the read-only file ID to fail because it was trying to flush information out of the file. Solution: Check the permissions on file IDs that are being closed and only flush when the particular file ID was opened with write permission. Platforms tested: FreeBSD 4.9 (sleipnir) too small to need h5committest Misc. update:
* [svn-r7456] Purpose:Bill Wendling2003-09-109-59/+201
| | | | | | | | | | | | | | | | | | | | | Removal of H5AC_find() Description: The H5AC_find() function is mostly redundant and with the new Flexible Parallel HDF5 stuff, we need to do locking on metadata returned from the H5AC_find() anyway. So, all of the locking stuff will be placed in the H5AC_{un}protect() functions. The H5AC_find() is no longer needed. Solution: Replaced all H5AC_finds with H5AC_protects and H5AC_unprotects. Platforms tested: Linux (Fortran & C++) Solaris (Fortran) Irix (Parallel & Fortran) Misc. update:
* [svn-r7453] Purpose:Quincey Koziol2003-09-104-41/+60

* [svn-r7446] Purpose:Quincey Koziol2003-09-066-34/+58
| | | | | | | | | | | | Code cleanup/bug fix Description: Move metadata cache calls around a bit so they protect the usage of the metadata better. Platforms tested: FreeBSD 4.9 (sleipnir) too small to need h5committest
* [svn-r7445] Purpose:Bill Wendling2003-09-045-26/+78
| | | | | | | | | | | | | | | | | | | | | Fix, of a sort Description: Some of the code would get an object from the cache via the H5AC_find() function and then modify the returned object. This behavior is incorrect as the pointer returned via the H5AC_find() function is supposed to be read only. Solution: Changed the H5AC_finds to H5AC_protect() instead and added the appropriate H5AC_unprotect() function. Platforms tested: (simulated h5committest by hand since it doesn't work for me) Linux (Fortran, C++) Solaris (Fortran) AIX (Fortran, C++) SGI (Parallel, Fortran)

| | | | | | | | | | | | | | | | | Bug fix Description: The VFL driver ID in a file's access proprty list wasn't being reference counted correctly, causing the VFL driver to get prematurely closed after several calls to "H5Pget_access_plist->H5Pclose". Solution: Increment VFL driver ID reference count when copy of file's access property list is made in H5Pget_access_plist() Platforms tested: FreeBSD 4.9 (sleipnir) h5committest

| | | | | | | | | | | | | | | | | | | | Bug Fix and code cleanup Description: Correct error in H5T_detect_class that was causing nested compound datatypes with to not detect the datatype class of fields correctly, which caused errors with fill-values, variable-length datatypes and chunks later on. Return the rank of the array datatype from H5Tget_array_dims(), like H5Sget_dims(). Lots of cleanups to datatype code, to make the handling of arrays, compound types, variable-length strings and sequences and enumerated types more consistent and robust.

| | | | | | | | | | | | | | | | | Bug fix Description: When datasets are deleted from a file, they are removed from the sieve buffer, but instead of invalidating only the part of the sieve buffer affected, the sieve buffer code would throw away the entire sieve buffer, potentially including other raw data in the buffer that hadn't been written to disk yet. Solution: Improve the sieve buffer clearing code to handle partial invalidations. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest

| | | | | | | | | | | | | | | | | | | Bug fix Description: H5Gget_objname_by_idx should allow NULL for the 'name' parameter, to allow for querying for the name's length. Solution: Allow NULL for the 'name' parameter, the internal functions were already ready to handle that case. Clean up RM information about H5Gget_objname_by_idx and H5Gget_objtype_by_idx also.
