| | | | | | | | | | | | | | | | | | | | | | | Commit metadata tagging framework. Description: This check-in contains a new framework whose goal is to apply a tag value to each new entry in the metadata cache as it is created. This tag value is such that it relates each piece of metadata to the HDF5 object that it belongs to (dataset, group, et cetera). This changeset includes the framework that applies the tags as well as a suite of tests to verify correct tag application, though does not yet make use of the tag values to flush/evict individual objects. Please refer to the "flush/evict individual objects" RFC for further discussion of these changes. Tested: jam, amani, linew (h5committest) liberty, abe, blue print

* [svn-r12902] Checkin of Shared Object Header Message work.James Laird2006-11-131-0/+1
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r12528] Added User-Defined links to the library.James Laird2006-08-021-2/+9
| | | | | | | | | | | | | | 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-r12462] Committed a variety of metadata cache related changes:John Mainzer2006-07-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | 1) Added trace file support to the metadata cache. This allows capture of all metadata cache calls in trace files for purposes of optimization and debuging. 2) Added an expunge entry function. This allows an entry to be deleteded from the cache without writing it to disk even if it is dirty. 3) Added a function call to resize pinned entries. 4) Added code to deal with entries that are dirty on load. This is needed in support of a bug fix which can alter object headers on load to repair files. 5) Added progress reporting code to the "MDC API smoke check" test in cache_api.c. To enable the progress reporting, set report_progress to TRUE in mdc_api_call_smoke_check(). Tested with h5committest, and a parallel test on phoenix (dual athelon linux box).
* [svn-r12452] Purpose:James Laird2006-07-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | Add pinned entry capability to cache. Description: For frequently accessed cache entries, the protect/unprotect overhead is sometimes a bottleneck. Solution: Allow entries to be pinned in the cache. Pinned entries can't be evicted, but can be flushed or modified.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.... :-)

| | | | | | | | | | | | | | | | | | | | | 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.... Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 Mac OS X
* [svn-r11277] Purpose:Quincey Koziol2005-08-201-1/+1
| | | | | | | | | | | | | | | Bug fix Description: Fix core dump when checking whether to invalidate the name of an object when unlinking an object in a group opened through an object reference. Solution: Check if names of various objects are valid before comparing them, etc. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11195] Purpose:Albert Cheng2005-08-041-0/+3

* [svn-r10184] Purpose:Quincey Koziol2005-03-111-0/+1
| | | | | | | | | | | | | | | | | | | | New feature Description: Add new "block tracker" data structure to library, for tracking blocks of bytes in a file. Block trackers will be used to keep track of the blocks belonging to the soon-to-be-implemented "segmented heap" which is designed to replace the current local & global heaps (starting with the local heap). Block trackers will also keep track of the free space in the segmented heap and someday could be used to track the free space in the entire HDF5 file. They are implemented as a small header of information to cache the state of the blocks (max & min sizes of blocks tracked, etc.) and the records of the blocks themselves are stored in a v2 B-tree. Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti) h5committest
* [svn-r10153] Purpose:Quincey Koziol2005-03-051-0/+1

* [svn-r9971] Purpose:Quincey Koziol2005-02-091-0/+1
| | | | | | | | | | | | New feature Description: Checkpoint v2 B-tree code after getting 2 leaf record redistribution working and tested. Platforms tested: FreeBSD 4.11 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r9580] Purpose:Quincey Koziol2004-11-271-1/+9
| | | | | | | | | | | | | | | | | | | | Add new internal data structure Description: Add an implementation of skip lists to the library (see comment in src/H5SL.c for references to the papers describing them) as a potential replacement for our current threaded, balanced binary tree container. Skip lists are much simpler to implement and should be faster to use. Also, added new error codes to release branch, so bump the minor version number to indicate that the library is no longer perfectly compatible with the 1.6.3 release. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require further testing (the skip lists aren't actually used by any library code yet)
* [svn-r8791] Purpose: Rewrote metadata cache (H5AC.c, etc.) to improve ↵John Mainzer2004-07-021-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Platforms tested: eirene (serial, parallel, fp), h5committested Misc. update:
