* [svn-r16702] Purpose: Improve performance of factory free lists.Neil Fortner2009-04-081-2/+8
| | | | | | | | | | | Description: Factory free lists were formerly implemented as block free lists. This was inefficient as factories can only be one size, and implementing them as blocks (which can be variable size) wastedd computation and space. They have been rewritten with a separate implementation, which is simlar to regular free lists except they can be dynamically created and destroyed. Tested: jam, linew, smirom (h5committest)
* [svn-r16698] Purpose: Fix bug 503Neil Fortner2009-04-081-0/+4
| | | | | | | | | Description: Changed Skip list package to use a deterministic skip list. This allows the skip list package to avoid calling rand() and srand(), even on machines without rand_r(). There is no longer a p-value or maximum level for skip lists. Tested: jam, smirom, linew (h5committest)

* [svn-r12842] Description:Quincey Koziol2006-11-021-10/+10
| | | | | | | | | | | | | | | | Refactor generic property list initialization code to put property list specific routines in property list modules, instead of scattered to the four winds. Also, introduce property list class initialization objects, to make adding new property list classes in the library easier. Fix daily test failure by using H5Pget_elink_prefix() API routine instead of looking at the "raw" generic property list information.

* [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-r12452] Purpose:James Laird2006-07-051-8/+8
| | | | | | | | | | | | | | | | | | | | | | 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-r12440] Purpose:Quincey Koziol2006-06-271-3/+3

| | | | | | | | | | Description: Function prototype H5E_walk_t and structure H5E_error_t wasn't backward compatible. Solution: Make them compatible with v1.6 and provide new definitions of H5E_walk_stack_t and H5E_error_stack_t. Platforms tested: fuss and h5committest.
* [svn-r12261] Purpose:Albert Cheng2006-04-161-15/+16
| | | | | | | | | | | | Improvement Description: Modified the warning messages from the Version mismatch checking to suggest the users to try recompiling or checking the shared lib setting. Platforms tested: Tested in heping only since it was just a simple text string changes. (I did moved the strings around a bit.)

* [svn-r12138] Purpose: VMS portElena Pourmal2006-03-221-0/+36
| | | | | | | | | | | | | | Description: Unix remove function removes only the latest version of a file on VMS. Some of our tests create multiple versions of the testfiles and as a result, test programs may be confused, give false negative result, etc. Solution: Created HDremove_all function for VMS that removes all versions of the files. HDremove on VMS is an alias to HDremove_all. Platforms tested: VMS server and heping (to check that nothing is borken on UNIX side) Misc. update:
* [svn-r12110] Purpose:Leon Arber2006-03-161-15/+6
| | | | | | | | | | | | | | | | | | Optimization Description: Get rid of unnecessary function call for systems that don't have rand_r. Solution: If rand_r isn't present on a system, then macros can be used to simply call the underlying random function instead of calling the HDrand/HDsrand functions that keep track of the random seed within the library. Platforms tested: heping (minor change) Misc. update:
* [svn-r12021] Purpose:Leon Arber2006-03-071-2/+2
| | | | | | | | | | | | | | | Bug fix. Description: Fix typo. srand/srandom don't return anything, so don't attempt to return their value. Solution: Platforms tested: heping Misc. update:
* [svn-r12019] Purpose:Leon Arber2006-03-071-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix/Feature Description: Modify the library to use rand_r, when available, instead of srand. If rand_r is not available, it will try to use srandom/random, and then finally fall back to srand/rand. Solution: A couple places in the library use the srand() function to seed the random number generator. This can cause problems on certain platforms and could theoretically cause problems for users who expect a certain sequence of random numbers following their own call to srand(). Most platforms have an implementation of rand_r, which is identical to rand, except that it allows for explicit storage of the seed value. The configure script will now check for the existence of rand_r to facilitate its use in the library. Two new functions are added, to replace the macros HDsrand/HDrand. These functions are HDrand and HDsrand. HDrand will call rand_r, if available, or random(), if available, and fall back to rand() if neither of those is available. HDsrand will store the seed value locally, if rand_r is available. Otherwise, it will call srandom if available, and fall back to srand otherwise. Platforms tested: heping, mir. Really need to test on Red Storm, since that platform motivated this fix, but the machine is currently not available. Misc. update:
* [svn-r11991] Purpose:Albert Cheng2006-03-011-15/+0
| | | | | | | | | | | | | | | | | Porting. Description: Red Storm's lustre used srand and rand to initialize their user mode of lustre. HDF5 also uses srand and that messes up Lustre. Solution: Use -DRED_STORM to block out the HDF5 code that calls srand. This is a temporary fix since Lustre has fixed its code from calling srand and rand but the fix is not deployed at Red_storm yet. Platforms tested: Tested at Red-Storm.
* [svn-r11785] Purpose:Albert Cheng2005-12-111-0/+15
| | | | | | | | | | | | Patch for red-storm. Description: A temporary patch for redstorm, must open a file in the same parallel data filesystem before H5_init_library.

| | | | | | | | | | | | | New feature Description: Add in a combination of Peter's & my code to support copying variable-length data from one file to another, although currently only supported with contiguous data storage. Platforms tested: FreeBSD 4.11 (sleipnir) h5committest
* [svn-r11738] Purpose:James Laird2005-11-181-0/+25
| | | | | | | | | | | | | | | | | | | Configure feature Description: Added 'make trace' target. Solution: Added tracing to 1.7. This was done automatically in 1.6, but left out of 1.7 until now (oops!). Tracing in 1.7 only happens manually, when the user types 'make trace.' Tracing automatically requires more framework than it's worth. I also fixed a couple of tracing bugs and ran trace. Platforms tested: mir, sleipnir, modi4 Misc. update:
* [svn-r11735] Purpose:Albert Cheng2005-11-161-101/+0
| | | | | | | | | | | | | | | | | | Cleanup. Description: Removed the home-made version of snprintf and vsnprintf since they do not actually enforce the size parameter correctly and could corrupt memory or as a security hole. This block of code has been turned off since Aug 11, 2005 for all platforms except Tflops. No one has reported any problem since--sort of empirical evidence that all platforms except Tflops support both functions. Tflops has retired in September. So, no need to keep this block of code. Also, fixed the HDxxx macro to call the corresponding xxx function. Platforms tested: Tested in heping, both serial and parallel.
* [svn-r11733] Purpose:Quincey Koziol2005-11-161-5/+5
| | | | | | | | | | | | | | | | | | Code cleanup Description: Added some comments about the thread-specific memory for the error and function stacks. Changed H5close() to not use the function stack (since it causes it to be re-enabled after shutting it down) Changed thread-safe semaphore code to not use dynamicly allocated memory. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 Too minor to require 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.... :-)

| | | | | | | | | | | | | | Bug fix. Description: Reactivated the code for snprintf and vsnprintf for Tflops but added the SN_SIZ_MIN as an attempt to require the minimum amount of space needed, hoping vsnprintf/snprintf do not print larger than it per request. Also added code to detect overflow and return error (IF overflow has not crashed the application yet.) These are all short term patches. Platforms tested: Tested at Tflops.

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

* [svn-r9234] Purpose:Quincey Koziol2004-09-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Tweak recent "forward compatibility" changes to the H5E* API (which allowed for the old H5E API functions to remain unchanged) by allowing for the error stack callback function (H5E_auto_t) to also remain unchanged from the 1.6 branch. This required changing the H5E{get|set}_auto routines to have the old style H5E_auto_t type (which didn't have a stack ID parameter) and the new H5E{get|set}_auto_stack routines to have a newer "H5E_auto_stack_t" type (which has a stack ID parameter). This should make the H5E API changes as forwardly compatible as possible. One side-affect of this change was that it was impossible to determine if the current auto error callback was the old style (H5E_auto_t) or the new style (H5E_auto_stack_t) of callback, so a new API function (H5Eauto_is_stack) was adde to query this.

* [svn-r9183] Purpose: New featureRaymond Lu2004-09-011-5/+1
| | | | | | | | | | | | 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.

* [svn-r8791] Purpose: Rewrote metadata cache (H5AC.c, etc.) to improve ↵John Mainzer2004-07-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
