* [svn-r11077] Purpose:Quincey Koziol2005-07-161-1/+2
| | | | | | | | | | | | Bug fix Description: Further progress on fixing file mounting to work properly. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 Too minor to require h5committest
* [svn-r11022] Purpose:Quincey Koziol2005-07-051-0/+31
| | | | | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Don't unmount child files from a parent file if the parent file is being held open by an object. Also, moved the mounting routines into their own source file and the superblock routines into their own file also. Solution: Moved the code for unmounting child files down in the H5F_close routine and also add checks to the file and group mounting code to unmount child files when the last object holding open a file closes. Platforms tested: FreeBSD 4.11 (sleipnir) h5committest

| | | | | | | | | | | | | | | | | | | | | | | | | | | Interim checkin of code changes moving management of the is_dirty flag into the cache code. Description: Prior to this checkin, management of the is_dirty flag was handled above the level of the metadata cache. This can no longer be allowed, as it introduces a race condition in the proposed fix for a cache coherency bug in PHDF5. Solution: Move management fo the is_dirty flag to the cache code proper. Entries are now marked as dirty via a flag on the unprotect call. Platforms tested: h5committested Misc. update:

* [svn-r10837] Purpose:Quincey Koziol2005-06-011-0/+5
| | | | | | | | | | | | | | | | | | | | | Bug fix/new feature Description: Setting "SEMI" or "STRONG" file close degrees causes problems when multiple file IDs exist for the same file on disk. Solution: Make the "SEMI" and "STRONG" settings only apply to the file ID that is being closed. Also, add an "H5F_OBJ_LOCAL" flag for the H5Fget_obj_count() & H5Fget_obj_ids() calls, so that applications can query about objects opened with a particular file ID instead of all the objects opened in the file on disk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".

| | | | | | | | | | | | | | | | | | | | | Code cleanup & optimization Description: Improve ADF/CGNS benchmark by reducing the number of internal attribute copies made during creations, opens and writes. Added new H5O_iterate() routine for iterating through messages of a certain type in the object header (attributes are the only message currently that can have multiple instances in the object header). Cross-pollinated various minor code cleanups to reduce diffs between branches. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest

* [svn-r9329] James Laird2004-09-281-51/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

* [svn-r9310] Purpose:Quincey Koziol2004-09-221-0/+27
| | | | | | | | | | | | | | Code optimization Description: Avoid performing a check on the number of objects in a group (which currently involves iterating over all entries in the group's B-tree) before calling H5G_get_obj<foo>_by_idx. Instead, just have H5G_get_obj<foo>_by_idx() notice when you've walked off the end and return fail then. Platforms tested: FreeBSD 4.10 (sleipnir) h5committest
* [svn-r9183] Purpose: New featureRaymond Lu2004-09-011-6/+6
| | | | | | | | | | | | Description: Restore 6 old error API functions back to the library to be backward compatible with v1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, H5Eset_auto, H5Eget_auto. These functions do not have error stack as parameter. Solution: Internally, these functions use default error stack. Platforms tested: h5committest and fuss. Misc. update: RELEASE.txt
* [svn-r8897] James Laird2004-07-201-0/+7
| | | | | | | | | | | | | | | | | Purpose: Bug Fix Description: Trying to create the root group or the working group ("/" or ".") fakes out HDF5 so that it neither creates a group nor returns an error. Solution: H5G_namei now throws an error if it was supposed to insert but didn't. Platforms tested: sleipnir, Visual Studio 7 (very minor change) Misc. update:
* [svn-r8844] Purpose:Quincey Koziol2004-07-091-0/+5
| | | | | | | | | | | | | | | | | | Bug fix Description: The "shared" raw B-tree node can get freed before all the B-tree nodes had been flushed out to disk and released by the cache. Solution: Implement a simple reference counting wrapper for objects in the library and use it to hold the shared raw B-tree nodes so they aren't freed before all references to them in memory are released. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) IRIX64 6.5 (modei4)
* [svn-r8731] Purpose:Quincey Koziol2004-06-231-14/+11
| | | | | | | | | | | | | | | Code cleanup & minor optimization Description: Re-work the way interface initialization routines are specified in the library to avoid the overhead of checking for them in routines where there is no interface initialization routine. This cleans up warnings with gcc 3.4, reduces the library binary size a bit (about 2-3%) and should speedup the library's execution slightly.

| | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: 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.

| | | | | | | | | | | | | | | | Bug fix Description: H5Gget_num_objs, H5Gget_objname_by_idx and H5Gget_objtype_by_idx were only accepting a group ID, instead of a location ID, as our documentation for them stated. Solution: Allow them to accept a location ID. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7377] Purpose:Quincey Koziol2003-08-161-12/+103
| | | | | | | | | | | | | | | | Bug fix Description: Linking and unlinking objects with multiple internal and/or trailing '/'s was not handled well in the library.

| | | | | | | | | | | | | | | Code cleanup. Description: Move many package or internal function prototypes and macro definitions into tighter scope according to their current use. Added more comments where appropriate. Eliminate ancient, unused functions. Added a couple "accessor" functions to get parts of data structures which were moved out of scope. Platforms tested: h5committested
* [svn-r6825] Purpose:Quincey Koziol2003-05-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | New feature/enhancement Description: Chunked datasets are handled poorly in several circumstances involving certain selections and chunks that are too large for the chunk cache and/or chunks with filters, causing the chunk to be read from disk multiple times. Solution: Rearrange raw data I/O infrastructure to handle chunked datasets in a much more friendly way by creating a selection in memory and on disk for each chunk in a chunked dataset and performing all of the I/O on that chunk at one time. There are still some scalability (the current code attempts to create a selection for all the chunks in the dataset, instead of just the chunks that are accessed, requiring portions of the istore.c and fillval.c tests to be commented out) and performance issues, but checking this in will allow the changes to be tested by a much wider audience while I address the remaining issues.
