* [svn-r7699] Purpose:Bill Wendling2003-10-221-48/+41
| | | | | | | | | | | | | | | | | | | Bug Fix Description: The owners and reference counts of locks weren't being handled correctly. Solution: Allocate an array the size of the COMM FPHDF5 is invoked with for each lock. Then reference count within this array. Keep an extra "counter" to see how many different processes have this particular lock. Free the lock when that counter reaches zero. Platforms tested: Linux & Copper (FPHDF5 specific). Misc. update:

* [svn-r7682] Purpose:Quincey Koziol2003-10-211-210/+164
| | | | | | | | | | | | | | | Bug fix Description: Remove the [duplicated] native C9x datatype initializatin code from H5T.c and let the automatically generated code in H5Tinit.c handle initializing them, if they are allowed by the compiler. Platforms tested: FreeBSD 4.9 (sleipnir) Linux 2.4 (verbena, eirene) probably should be h5committested, but it's late and I'm fairly certain this will fix the problem... :-/
* [svn-r7675] Purpose:Quincey Koziol2003-10-201-2/+2
| | | | | | | | | | | | | | | Bug fix Description: Avoid "OPAQUE" symbol in template macro invocation, since it's already defined as a macro on Windows. Solution: OPAQUE -> OPAQ Platforms tested: FreeBSD 4.9 (sleipnir) Windows ? (Pedro's machine :-)
* [svn-r7674] Purpose:Quincey Koziol2003-10-201-5/+5

* [svn-r7669] Purpose:Quincey Koziol2003-10-202-1234/+379
| | | | | | | | | | | | | | | Refactor code Description: Use "template macro" technique to eliminate a huge amount of repeated code in type initialization code (almost 1000 lines, between this change and the changes to the H5Tconv.c file earlier). This centralizes the common parts of the code and makes the different parts of the code more obvious. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest

* [svn-r7667] Purpose:Quincey Koziol2003-10-181-7/+6
| | | | | | | | | | | Optimize code Description: Eliminate some computations from inner loop, giving about a 5% speedup. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to h5committest
* [svn-r7666] Purpose:Quincey Koziol2003-10-181-125/+81
| | | | | | | | | | | Code cleanup Description: Remove duplicated "core" conversion macros. Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest
* [svn-r7665] Purpose:Quincey Koziol2003-10-181-203/+58
| | | | | | | | | | | | Refactored code Description: Switched float->double and double->int conversions to use new, more generic conversion looping macros. Platforms tested: FreeBSD 4.9 (sleipnir) too small to require h5committest
* [svn-r7664] Purpose:Quincey Koziol2003-10-181-75/+124
| | | | | | | | | | | | | | More refactoring Description: Re-wrote inner loop of integer conversion routines with "psuedo-template" macros, to hoist 'if-else's out of inner loop in an easy to understand way. This speeds up the integer type conversions by 15-20%. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7663] Purpose:Quincey Koziol2003-10-181-106/+40
| | | | | | | | | | | | Code cleanup Description: Re-wrote duff's device with some macro substitution to make algorithm more obvious. Platforms tested: FreeBSD 4.9 (sleipnir) too small to require h5committest
* [svn-r7662] Purpose:Quincey Koziol2003-10-182-194/+225
| | | | | | | | | | | | | | | | | Refactor integer conversion macros Description: Turned integer conversion macros "inside" out, using an interlocking macro technique similar to templates in C++. The macro which actually performs the conversion is now invoked "genericly" from inside another macro, which will allow the inner conversion loop to be optimized in a much easier way. This "psuedo-template" technique could be useful for other semi-repetitious patterns in the library - possibly the datatype initialization code...

* [svn-r7616] Purpose:Quincey Koziol2003-10-1310-180/+233
| | | | | | | | | | | | | | | Code cleanup Description: Change field member count and indices for compound and enumerated types from 'int' to 'unsigned' to better reflect actual use. Cleaned up a few other minor compiler warnings, etc. Platforms tested: FreeBSD 4.9 (sleipnir) Linux 2.4 (verbena) too minor to require h5committest
* [svn-r7614] Purpose:Quincey Koziol2003-10-133-80/+87

* [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

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

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

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

| | | | | | | | | | | | | | | | 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)

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

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

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