* [svn-r12495] Description:Quincey Koziol2006-07-251-1/+1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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:

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

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

| | | | | | | | | | | | | | | | New feature Description: Add some additional features to the skip list code that was needed to fully support all the features that the threaded, balanced binary tree code has.

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

| | | | | | | | | | | | | New internal feature Description: Add a "release" routine to the skip lists, which releases all the nodes in the skip list, but keeps the skip list active. Platforms tested: FreeBSD 4.10 (sleipnir) Linux 2.4 (verbena) Too minor to require h5committest

| | | | | | | | | | | | | | | | | | | | Bug fix Description: Correct off-by-on error which could cause invalid # of levels to be used for a skip list node, in rare circumstances. Change from srandom()/random() to more portable srand()/rand() routines for random # generation. Pre-compute the probability factor for computing the level of new nodes, for a minor speedup.

* [svn-r9580] Purpose:Quincey Koziol2004-11-271-0/+715
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)
