* [svn-r14020] Description:Quincey Koziol2007-07-261-0/+2
| | | | | | | | | | | Correct error in size of v2 B-tree metadata prefix, which could cause too many entries to get inserted into a node, eventually causing either a file corruption bug (if debugging asserts were off) or a core dump on the assertion which checked this. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r13926] Description:Quincey Koziol2007-06-291-25/+44
| | | | | | | | | | | | Add small interface to "wrap" a static buffer (usually on the stack), but still allow for buffers larger than the static buffer to be allocated. This can eliminate _many_ short-lived buffer allocations in situations where the buffer is a predictable size (or at least a "very likely" size). Also, some minor code cleanups, particularly in the SOHM caching code. Tested on: Mac OS X/32 10.4.10 (amazon)
* [svn-r13773] Description:Quincey Koziol2007-05-201-14/+14
| | | | | | | Reduce compiler warnings w/gcc 4.2 Tested on: FreeBSD/32 6.2 (duty) w/gcc 4.2
* [svn-r13253] Updated all C and C++ style source code files with the THG ↵Albert Cheng2007-02-071-2/+3
| | | | | | | | | copyright notice. Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.
* [svn-r12774] Modified flush code in the metadata cache to allow it toJohn Mainzer2006-10-181-6/+23
| | | | | | | | | | | | | | | | | handle flush callbacks which can dirty other entries, and resize and/or rename the target entry. This feature is needed by the fractal heap code. Also added associated test code. H5Commit tested. Test failed on heping, but the error appears to be a syntax error in an un-related file. Tests on copper & sol passed, along with tests on phoenix.
* [svn-r12768] Description:Quincey Koziol2006-10-161-6/+6
| | | | | | | | | | Add 'initval' parameter to "lookup3" checksum routine (and implicitly to the metadata checksum routine), to allow chaining several checksums together easily (which isn't used by these modules, but will be used in my next checkin) Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12644] Description:Quincey Koziol2006-09-051-57/+25
| | | | | | | | | | | | | 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-r12631] Description:Quincey Koziol2006-08-261-24/+62
| | | | | | | | | | | | | | | | | 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-r12619] Description:Quincey Koziol2006-08-231-5/+5
| | | | | | | | | | | Fix off-by-one error in computing the size of metadata prefixes for v2 B-tree internal & leaf nodes. General code cleanup and reformating. Tested On: Mac OS X.4/PPC (amazon) Too minor to require h5committest
* [svn-r12615] Description:Quincey Koziol2006-08-221-8/+61
| | | | | | | | Add checksum to v2 B-tree metadata. Tested On: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12613] Description:Quincey Koziol2006-08-221-218/+218
| | | | | | | Reorder metadata cache callbacks to be more sensible. Tested on: None - just eyeballed, very simple change
* [svn-r12589] Description:Quincey Koziol2006-08-171-4/+4
| | | | | | | | | | | | | | Revert passing the v2 B-tree class to callbacks, it turns out to be unnecessary. Also revert have a "class private" pointer for each v2 B-tree class. Add in support for the different flavors of fractal heap 'huge' objects also. Tested on: FreeBSD/32 4.11 (sleipnir) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12561] Description:Quincey Koziol2006-08-101-14/+14
| | | | | | | | | | | | Update code formatting a little and refactor to add a better mechanism for performing callbacks when removing records from the B-tree or deleting entire B-tree. Testing: FreeBSD 4.11 (sleipnir) Linux/64 2.4 (mir) Linux/32 2.4 (heping) Mac OS 10.4 (amazon)

| | | | | | | | | | | | | | | | | | | New feature & code cleanup Description: Change some references from 'keys' to 'records', which is more correct for this implementation.
