* [svn-r9599] Purpose:Quincey Koziol2004-11-293-16/+60
| | | | | | | | | | | | | 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
* [svn-r9597] Purpose:Quincey Koziol2004-11-294-248/+195
| | | | | | | | | | | | | Code optimization Description: Retarget metadata cache code from using TBBT routines to using new skiplist routines, for a reasonable speedup (when dealing with dirty metadata) Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r9593] Purpose:Quincey Koziol2004-11-291-2/+4
| | | | | | | | | | | | | | | | | Bug fix Description: Re-work array of 'forward' pointers in a way that makes the PGI compiler more happy. Solution: Change from 'H5SL_node_t *forward[1]' to 'H5SL_node_t **forward' and change how array of forward pointers is dealt with. Platforms tested: Linux 2.4 (verbena) w/PGI FreeBSD 4.10 (sleipnir) Configuration not tested w/h5committest
* [svn-r9590] Snapshot version 1.6 release 4 (snap0).Albert Cheng2004-11-291-2/+2
| | | | | | | This replaced the snapshot release 1.6.4-pre1 which had the wrong release string because -preN is reserved for Pre-release test versions. Snapshot releases are named as -snapN for the release branch.

* [svn-r9588] Purpose:Quincey Koziol2004-11-281-9/+13
| | | | | | | | | | | | | | | | | | | | 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. Platforms tested: FreeBSD 4.10 (sleipnir) IRIX64 6.5 (modi4) Solaris 2.8 (sol) AIX 5.1(?) (copper)
* [svn-r9586] Purpose:Quincey Koziol2004-11-272-39/+25
| | | | | | | | | | | | | | Code optimization Description: Begin de-orbital burn of threaded, balanced binary tree code use by switching file open object code over to using them. Initial benchmarks show that skip lists are 5-10x faster than our TBBT code... Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r9583] Purpose:Quincey Koziol2004-11-272-5/+6
| | | | | | | | | | | | | | | Code optimization Description: Revise mechanism for calling H5open/H5check to better avoid calling them from internal libray code. Only copy a datatype's group entry information if it has some. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r9582] Purpose:Quincey Koziol2004-11-276-34/+58
| | | | | | | | | | | | | | | | | | | | 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-r9334] James Laird2004-09-2841-2131/+2446
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Feature Description: (Same change to release branch) Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip. Platforms tested: Visual Studio 7, sleipnir, arabica, verbena Misc. update:
* [svn-r9331] Purpose:Quincey Koziol2004-09-281-4/+3
| | | | | | | | | | | Bug fix Description: Another attempt to fix the address overflow in the core VFL, hopefully one that works on 64-bit platforms. Platforms tested: AIX 5.1 (copper)
* [svn-r9328] Purpose:Quincey Koziol2004-09-282-12/+1
| | | | | | | | | | | | | Bug fix. Description: Fix off-by-one error in Core VFL driver which would cause spurious address or size overflow errors when an odd valued address or size was checked. Platforms tested: FreeBSD 4.10 (sleipnir) Linux 2.4 (heping) Solaris 2.7 (arabica)
* [svn-r9323] Purpose:Quincey Koziol2004-09-271-66/+104
| | | | | | | | | | | | | Bug fix Description: Fix situation where deleting a chunked datasets with B-tree nodes that weren't in the metadata cache would die with a core dump. Platforms tested: FreeBSD 4.10 (sleipnir) Linux 2.4 (heping) Solaris 2.7 (arabica)
* [svn-r9313] Purpose:Quincey Koziol2004-09-231-3/+4

* [svn-r9311] Purpose:Quincey Koziol2004-09-221-0/+36
| | | | | | | | | | | | | | Code optimization Description: Avoid performing a check on the number of objects in a group (which currently involves iterating over all entries in the group's B-tree) before calling H5G_get_obj<foo>_by_idx. Instead, just have H5G_get_obj<foo>_by_idx() notice when you've walked off the end and return fail then. Platforms tested: FreeBSD 4.10 (sleipnir) h5committest
