* [svn-r12644] Description:Quincey Koziol2006-09-051-46/+69
| | | | | | | | | | | | | Improve density of the B-tree further. For greater depths of B-trees, the gains are over 100%... Also, don't split internal nodes with 3->4 splits, use a 1->2 split instead, so that the density of the nodes around a split is maximized. Tested: Mac OS X/PPC 10.4 (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12638] Description:Quincey Koziol2006-09-041-4/+3
| | | | | | | | | | | | Split edge nodes in the tree with a 1->2 node split, instead of a 2->3 node split, which creates a more dense tree when a pattern of record insertions occurs (because it leaves behind full nodes instead of 2/3 full nodes). Tested: FreeBSD/32 4.11 (sleipnir) Linux/64 2.4 (mir) Linux/32 2.4 (heping) Solaris/64 2.9 (shanti)
* [svn-r12631] Description:Quincey Koziol2006-08-261-19/+20
| | | | | | | | | | | | | | | | | Refactor the file storage of "twig" nodes in the B-tree to allow them to store more records, increasing the average density of the B-tree 30-40%. Increase # of records in "insert lots" regression test to still create B-tree of depth 4 Update h5debug to interpret difference of 'branch' and 'twig' internal nodes in B-tree correctly. Tested on: FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)

* [svn-r12561] Description:Quincey Koziol2006-08-101-29/+39

* [svn-r11712] Purpose:Quincey Koziol2005-11-151-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Koziol2005-11-071-6/+25
| | | | | | | | | | | | | | | | | | | 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-r11245] Purpose:Quincey Koziol2005-08-131-43/+43
| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11014] Purpose:Quincey Koziol2005-07-021-350/+154
| | | | | | | | | | | | Code cleanup Description: Refactor metadata cache to merge "dirtied" flag in with other flags for H5AC_unprotect and H5C_unprotect. Platforms tested: FreeBSD 4.11 (sleipnir) h5committest
* [svn-r10978] Purpose:John Mainzer2005-06-241-157/+551
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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:
