* [svn-r12906] Description:Quincey Koziol2006-11-131-8/+5
| | | | | | | | | | | | | | | | Straighten out some convoluted code when links were being deleted, which could cause the "delete" callback for user-defined links to not get called when the group they were in was deleted. Had to compromise on the "delete" callback though - only calls the callback with the ID for the file the link is in, instead of the group, since the group is being held open upstream in the calling sequence during a group deletion and this prevents a group and its ID from being created. (This could possibly be worked around, but would cause a fair bit of havoc in the code and I'm not entirely certain it's worth it...) Tested on: Linux/32 2.6 (chicago)
* [svn-r12902] Checkin of Shared Object Header Message work.James Laird2006-11-131-120/+593
| | | | | | | | | | | | This feature is still in progress; Shared Object Header Messages are not complete as a feature and are not thoroughly tested. There are still "TODO" comments in the code (comments with the word "JAMES" in them, so as not to be confused with other TODO comments). Hopefully this checkin will reduce the liklihood of conflicts as I finish implementing this feature. All current tests pass on juniper, copper (parallel), heping, kagiso, and mir.

| | | | | | | | | | | | | | Finish new version of the I/O pipeline message, which is much smaller than the previous version. This version is used with the "use the latest version of the format" flag. Closed several memory leaks/overruns (found with valgrind). Also, lots of compiler & formatting cleanups. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)

| | | | | | | | | | | | | | | | | More fixes to make the I/O & memory operations more efficient when loading & flushing object header chunks. Add in concept of a chunk having a "gap" at the end - unused space that is not large enough to hold a full null message that describes it. Clean up formatting a bit.

* [svn-r12770] Description:Quincey Koziol2006-10-161-75/+103
| | | | | | | | | | | | | | | Overhaul usage of object header chunks to reduce I/O operations and memory allocations. The object header prefix is now stored in the first object header chunk's "image" in memory. Also, lots of formatting cleanups.

* [svn-r12708] Description:Quincey Koziol2006-10-031-0/+2
| | | | | | | | | | | | | | | | | | | Add the "use the latest version of the format" support to datatype messages. And a regression test to check that it's working. Also, found that we have been over-allocating space for compound datatype messages (when they have array datatypes or can use the latest version of the format) and trimmed the size back. Clean up datatype & dataspace encode/decode routines by having them allocate & release "fake" file structures, which gets them out of needing to "know" about the internals of file structures. Other minor whitespace/formatting cleanups, etc. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | File format is not stable, don't keep files produced! Description: First stage of checkins modifying the format of groups to support creation order. Implement "dense" storage for links in groups. Try to clarify some of the symbols for the H5L API. Add the H5Pset_latest_format() flag for FAPLs, to choose to use the newest file format options (including "dense" link storage in groups) Add the H5Pset_track_creation_order() flag for GCPLs, to enable creation order tracking in groups (although no index on creation order yet). Remove --enable-group-revision configure flag, as file format issues are now handled in a backwardly/forwardly compatible way. Clean up lots of compiler warnings and other minor formatting issues.

* [svn-r12686] Added compression to Packet Tables. Now both C and C++ packet ↵James Laird2006-09-261-0/+1
| | | | | | | | | | | | | | | | tables have an extra parameter that sets the deflate filter. Added tests, made examples use the new APIs. Cleaned up include files a little and removed some casts that I hope are superfluous. If anybody encounters strange errors in the packet table tests where the chunk size is set to some extremely large value, please let me know, but I was unable to reproduce this error on any system. Tested on mir, heping, sol, juniper, VS 6.0. Looked for the chunk size error on several other systems a month or two ago.

* [svn-r12596] Refactored how external files are opened and closed.James Laird2006-08-181-8/+94
| | | | | | | | Object header locations (H5O_loc_t's) can now "hold open" a file and decrement its open object count when they close. This means that locations (H5O_loc_t's and H5G_loc_t's) should always be freed. Added more thorough tests to ensure that external files are closed.
* [svn-r12528] Added User-Defined links to the library.James Laird2006-08-021-1/+399
| | | | | | | | | | | | | | Users can create external links using H5L_create_external(). These links point to an object in another HDF5 file. Users can alter the behavior of external links or create new kinds of links by registering callbacks using the H5L interface. Added tests, tools support, etc. Also a number of other, minor changes have been made (some restructuring of the H5L interface, for instance). Additional documentation and examples are forthcoming.

| | | | | | | | | | | | | | | | Bug fix Description: Retrieving an object's name could fail (in various ways) under certain circumstances (mostly having to do with mounted files). Solution: Re-write & simplify "get object name" code to fix error in a better way than adding yet another hack to the previous pile of hacks... :-) Platforms tested: FreeBSD 4.11 (sleipnir) h5committest

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature Description: Check in baseline for compact group revisions, which radically revises the source code for managing groups and object headers. WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! This initiates the "unstable" phase of the 1.7.x branch, leading up to the 1.8.0 release. Please test this code, but do _NOT_ keep files created with it - the format will change again before the release and you will not be able to read your old files!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! Solution: There's too many changes to really describe them all, but some of them include: - Stop abusing the H5G_entry_t structure and split it into two separate structures for non-symbol table node use within the library: H5O_loc_t for object locations in a file and H5G_name_t to store the path to an opened object. H5G_entry_t is now only used for storing symbol table entries on disk. - Retire H5G_namei() in favor of a more general mechanism for traversing group paths and issuing callbacks on objects located. This gets us out of the business of hacking H5G_namei() for new features, generally. - Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t - Lots more... Platforms tested: h5committested and maybe another dozen configurations.... :-)
* [svn-r11686] Purpose:Quincey Koziol2005-11-071-61/+470
| | | | | | | | | | | | | | | | | | | New feature Description: Add in baseline "object copy" code from Peter [in the form of a new API routine: H5Gcopy()]. There's still some work to do (like handling variable- length datatypes and possibly support for references) and it hasn't been tested on mounted files yet, but the core functionality is there and working correctly. I've also got a set of patches to update the 1.6 branch with tweaks to keep the branches mostly in sync, but Elena will kill me if I import them before the 1.6.5 release is out... :-) Platforms tested: FreeBSD 4.11 (sleipnir) h5committested

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Repair synchronization bug in the metadata cache in PHDF5 Also repair numerous other bugs that surfaced in testing the bug fix. Description: While operations modifying metadata must be collective, we allow independant reads. This allows metadata caches on different processes to adjust to different sizes, and to place the entries on their dirty lists in different orders. Since only process 0 actually writes metadata to disk (all other processes thought they did, but the writes were discarded on the theory that they had to be collective), this made it possible for another process to modify metadata, flush it, and then read it back in in its original form (pre-modification) form. The possibilities for file corruption should be obvious. Solution: Make the policy that only process 0 can write to file explicit, and visible to the metadata caches. Thus only process 0 may flush dirty entries -- all other caches must retain dirty entries until they are informed by process 0 that the entries are clean. Synchronization is handled by counting the bytes of dirty cache entries created, and then synching up between the caches whenever the sum exceeds an (eventually user specified) limit. Dirty metadata creation is consistent across all processes because all operations modifying metadata must be collective. This change uncovered may bugs which are repaired in this checkin. It also required modification of H5HL and H5O to allocate file space on insertion rather than on flush from cache. Platforms tested: H5committest, heping(parallel & serial) Misc. update:

| | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Merge back changes from "compact group" work that improve the infrastructure of the library and may impact others. In this round of merging, that includes: - Move datatype allocation into single internal routine, instead of duplicated code that was spread out in a dozen or so places. - Clean up guts of object header routines (H5O_*) to allow for some of the fancieroperations that need to be performed on groups, along with some general improvements. - Added a new error code - Some minor cleanups in other code....

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