* [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-r12914] Description:Quincey Koziol2006-11-141-0/+7
| | | | | | | | Checkpoint partially working v2 B-tree delete by index code (ifdef'ed out) for further work. Tested on: Linux/32 2.6 (chicago)
* [svn-r12647] Description:Quincey Koziol2006-09-051-2/+2
| | | | | | | | | Eliminate redundant "B-tree type" byte from internal & leaf nodes. May possibly improve B-tree density in rare circumstances... Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12644] Description:Quincey Koziol2006-09-051-28/+34
| | | | | | | | | | | | | 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 Koziol2006-09-041-1/+14
| | | | | | | | | | | | 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 Koziol2006-08-261-10/+32
| | | | | | | | | | | | | | | | | 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 Koziol2006-08-231-7/+25
| | | | | | | | | | | 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 Koziol2006-08-221-3/+16
| | | | | | | | Add checksum to v2 B-tree metadata. Tested On: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12561] Description:Quincey Koziol2006-08-101-3/+6
| | | | | | | | | | | | 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)
* [svn-r12474] Quincey Koziol2006-07-151-5/+0
| | | | | | | | Clean up some compiler warnings. Tested on: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r12077] Purpose:Quincey Koziol2006-03-111-0/+5
| | | | | | | | | | | Code cleanup Description: Fix/update formatting, clean up typos, etc. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11968] Purpose:Quincey Koziol2006-02-271-0/+39
| | | | | | | | | | | | | | Incrementtal checkin Description: Revise & update v2 B-tree code to separate the internal package-specific routines from the library-callable "private" routines. Similar updates for the fractal heap code. Platforms tested: FreeBSD 4.11 (sleipnir) Mac OSX (amazon)
* [svn-r11966] Purpose:Quincey Koziol2006-02-271-12/+19

* [svn-r10094] Purpose:Quincey Koziol2005-02-261-0/+4
| | | | | | | | | | | | | | | New features & refactor Description: Add basic record removal (only handles level-0 B-trees currently) Add query routine to check the number of records in a B-tree Add debugging routine to check the address of the root node in the B-tree Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti)
* [svn-r9986] Purpose:Quincey Koziol2005-02-111-11/+11
| | | | | | | | | | | | | | | | | | | New feature & code cleanup Description: Change some references from 'keys' to 'records', which is more correct for this implementation. Added feature to allow preemptive 3 node record redistributions (for leaves only currently) Added feature to perform preemptive 3->4 node splits (for leaves only currently) Platforms tested: FreeBSD 4.11 (sleipnir) w/parallel Solaris 2.9 (shanti) w/purify Too minor to require h5committest
* [svn-r9971] Purpose:Quincey Koziol2005-02-091-1/+6

* [svn-r9955] Purpose:Quincey Koziol2005-02-081-0/+16
| | | | | | | | | | | | | | New feature & bug fix Description: Allow h5debug tool to dump "test" v2 B-trees correctly. Also, fix incorrect parameter passing that was causing failures on various platforms. Platforms tested: FreeBSD 4.11 (sleipnir) AIX 5.2 (copper)
* [svn-r9939] Purpose:Quincey Koziol2005-02-041-5/+64
| | | | | | | | | | | | | New feature Description: Expand v2 B-tree code to support splitting the root node when enough records are inserted and move metadata cache callbacks into their own source file. Platforms tested: FreeBSD 4.11 (sleipnir) w/parallel Too minor for h5committest
* [svn-r9928] Purpose:Quincey Koziol2005-02-031-0/+118
New feature Description: Add basic code for new B-tree implementation. They don't do much yet, aren't hooked up to anything yet and the format may change, but I'd like to start getting them into the daily tests. Platforms tested: FreeBSD 4.11 (sleipnir) w/parallel Too minor to require h5committest
