* [svn-r12528] Added User-Defined links to the library.James Laird2006-08-021-15/+77
| | | | | | | | | | | | | | 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.
* [svn-r12452] Purpose:James Laird2006-07-051-3/+3
| | | | | | | | | | | | | | | | | | | | | | Feature Description: Revised Link APIs. Solution: New link APIs use H5L* H5*create_expand do not create links to the objects created; this must be done manually with H5Llink. Added APIs to link an object given its ID (H5Llink), to copy links (H5Lcopy), and changed creation APIs (H5Lcreate_hard and H5Lcreate_soft) and query API (H5Lget_linkinfo instead of H5Gget_objinfo). All old APIs are still supported in H5Gdeprec.c . Platforms tested: sol, mir, copper Misc. update: Forgot to update MANIFEST and release docs. Will do after checkin.

* [svn-r12439] Purpose:Quincey Koziol2006-06-261-8/+42
| | | | | | | | | | | | | New feature Description: Check in Peter's code to add support for "shallow copy", "create intermediate groups", "no attributes" and "expand soft links" support. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (chicago) w/ & w/o group-revision enabled h5committest
* [svn-r12221] Purpose:Quincey Koziol2006-04-101-5/+13
| | | | | | | | | | | | | | | "Hide" file format changes (for now) Description: Add ifdef's (controlled by the --enable-group-revision configure flag) to disable group revision changes to the file format, in order to allow alpha release to go ahead without releasing an unsupported version into the wild.

* [svn-r11838] Purpose:Quincey Koziol2005-12-261-60/+14
| | | | | | | | | | | | | | | | 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 Koziol2005-11-071-33/+103
| | | | | | | | | | | | | | | | | | | 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
* [svn-r11490] Purpose:Quincey Koziol2005-10-031-0/+7
| | | | | | | | | | | | | | | Bug fix Description: Fix "double root open" bug and apply same fix to datasets & named datatypes. Also fix bug in symbol table entry lookup code that would "transfer" an object from one file handle to another file handle when the two file handles were opened on the same actual file.

| | | | | | | | | | | | | | | | Big fix Description: A group opened by dereferencing a object reference would not work for H5Giterate(), due to the local heap & B-tree information not being cached. Solution: Get the local heap & B-tree info & point to that structure instead of the group entry for the group. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest

* [svn-r10978] Purpose:John Mainzer2005-06-241-34/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Provide facilities in cache to allow us to avoid a potential cache consistency bug in the parallel case. 2) Clean up a off by one sanity checking bug. 3) Turn off execution of long running tests in debug mode. Description: 1) In the parallel case, all writes to metadata must be collective, but reads may not be. In pricipal, this allows us to different contents in different caches. This isn't a problem as long as the correct data is always on disk, but unless we can force certain writes immediately, that need not be the case. 2) & 3) should need no further explanation. Solution: 1) Add code allowing us to mark cache entries, and then force these entries to be flushed at a later time. Note that to actually avoid the bug, we will have to modify existing code to use these new features. 2) & 3) should need no further explanation. Platforms tested: heping (serial debug and production) committest (copper, sol, and heping). test failed on heping in the c++ portion of the build, but at Quincey's siggestion, I am proceeding with the checkin.

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

* [svn-r9183] Purpose: New featureRaymond Lu2004-09-011-3/+3
| | | | | | | | | | | | 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-r8946] Purpose:Quincey Koziol2004-07-261-0/+3
| | | | | | | | | | | | | | | | | | Code cleanup, sorta Description: Added ifdef sections for "H5_USING_PURIFY" in various places in the code, which are designed to reduce the spurious "uninitialized memory read" warnings from purify which are actually OK. Note that this macro will have to be turned on by adding it to the CFLAGS for the build - I didn't think it was important enough to add a configure flag for. Also, the changes in H5HG.c optimize the walks through the objects in a heap to only look at the 'used' entries instead of all the 'allocated' entries. Platforms tested: Solaris 2.7 (arabica) w/purify Not tested by h5committest
* [svn-r8874] Purpose:Quincey Koziol2004-07-141-9/+5
| | | | | | | | | | | | | | | | | | | | Bug fix Description: Correct problems with "resurrecting" a dataset in a file. (This occurs when a dataset which is open gets unlinked from the group hierarchy (making it "dead" and marked for deletion in the file) and then is re-linked to the group hierarchy). Note that the current solution applies only to datasets, further work will fix this for groups and named datatypes also. Also, fix the "debug" routines to be a little more helpful in certain situations. Additionally, fix a locking bug in the symbol table node splitting routine which could be [one of] the cause[s] of the file corruption in flexible parallel operation.

| | | | | | | | | | | | | | | | | Code optimization Description: Re-work the insertion of a new child into an existing node, to exploit some speedups for adding the rightmost child, since this is a very common case when appending records to an unlimited size dataset. Also, hoist the checks for the tree's 'K' value into a field in the shared information about the tree, instead of re-calculating them all the time.

* [svn-r8853] Purpose:Quincey Koziol2004-07-101-32/+58
| | | | | | | | | | | | | | | | | | | | Code optimization Description: Refactor B-tree code to extract all common information for a B-tree into a shared structure that is pointed to by all the nodes in tree (instead of being included in each node). Also re-order B-tree node comparison checks for chunked datasets to check for >= the upper node first, since the comparison is a bit "heavy" and this check is more likely to succeed when you are adding records to the dataset. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest (also, recent h5dump commits have broken testing...)
* [svn-r8844] Purpose:Quincey Koziol2004-07-091-5/+41
| | | | | | | | | | | | | | | | | | 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-r8823] Purpose:Quincey Koziol2004-07-071-6/+109
| | | | | | | | | | | | | | | Code optimization Description: Since the raw B-tree nodes are the same size and only used when reading in or writing out a B-tree node, move raw B-tree node buffer from being per node to a single node that is shared among all B-tree nodes of a particular tree, freeing up a lot of space and eliminating lots of memory copies, etc. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest

* [svn-r8791] Purpose: Rewrote metadata cache (H5AC.c, etc.) to improve ↵John Mainzer2004-07-021-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | performance. Description: Replaced the old metadata cache with a cache with a modified LRU replacement policy. This should improve the hit rate. Solution: Since we want to flush cache entries in increasing address order, I used the threaded binary B-tree code to store the cache entries. There is a fair bit of overhead here, so we may want to consider other options. While the code is designed to allow the support of other replacement algorithms, at present, only a modified version of LRU is supported. The modified LRU algorithm requires that a user selectable portion of the cache entries be clean. The clean entries are evicted first when writes are not permitted. If the pool of clean entries is used up, the cache grows beyond its user specified maximum size. The cache can also exceed its maximum size if the combined size of the protected (or locked) entries exceeds the maximum size of the cache.

* [svn-r8731] Purpose:Quincey Koziol2004-06-231-22/+14
| | | | | | | | | | | | | | | 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.

* [svn-r8721] Purpose: Bug fix and test.Raymond Lu2004-06-221-1/+10
| | | | | | | | | | | | | Description: Function H5Gget_objtype_by_idx failed to handle soft link object. The library returned object type by calling H5G_get_type through H5B_iterate. But H5G_get_type only deals with objects with valid header address which soft link doesn't have. Solution: In H5G_node_type, make soft link a special case by checking if the object type is H5G_CACHED_SLINK. Also added a test of soft and hard links to titerate.c Platforms tested: h5committest and RH 8(fuss).

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

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:

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

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

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

| | | | | | | | | | | | | | | | 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-r7369] Purpose:Quincey Koziol2003-08-151-3/+3
| | | | | | | | | | | | | | | | | Bug fix Description: The metadata cache 'destroy' callback routines need the file handle in order for certain callback routines (currently just the H5HG one) to perform extra cleanups. The recent change to call the 'destroy' callback from the 'clear' callback omitted this parameter. Solution: Add the file handle to the metadata cache 'clear' callbacks. Platforms tested: FreeBSD 4.8 (sleipnir) too small to need h5committest
