* [svn-r11965] Purpose:Quincey Koziol2006-02-241-1/+0
| | | | | | | | | | | | Maintenance Description: Remove half-built (half-baked? :-) implementation of B+tree, block tracker and segmented heaps. (In preparation for starting the new heap coding) Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (heping)
* [svn-r11686] Purpose:Quincey Koziol2005-11-071-0/+4
| | | | | | | | | | | | | | | | | | | 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 Koziol2005-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | 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-r10195] Purpose:Quincey Koziol2005-03-111-1/+6
| | | | | | | | | | | New feature Description: Add feature to modify an existing record in a B-tree Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti)
* [svn-r10184] Purpose:Quincey Koziol2005-03-111-1/+1
| | | | | | | | | | | | | | | | | | | | New feature Description: Add new "block tracker" data structure to library, for tracking blocks of bytes in a file. Block trackers will be used to keep track of the blocks belonging to the soon-to-be-implemented "segmented heap" which is designed to replace the current local & global heaps (starting with the local heap). Block trackers will also keep track of the free space in the segmented heap and someday could be used to track the free space in the entire HDF5 file. They are implemented as a small header of information to cache the state of the blocks (max & min sizes of blocks tracked, etc.) and the records of the blocks themselves are stored in a v2 B-tree. Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti) h5committest
* [svn-r10178] Purpose:Quincey Koziol2005-03-101-6/+6
| | | | | | | | | | Correct formatting Description: Move some typedefs out of the macro section into the typedef section Platforms tested: None, too minor to require any.
* [svn-r10176] Purpose:Quincey Koziol2005-03-101-0/+2
| | | | | | | | | | | New feature Description: Add routine to delete entire B-tree from a file. Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti)
* [svn-r10172] Purpose:Quincey Koziol2005-03-091-0/+9
| | | | | | | | | | | | | | Bug fix & New feature Description: Correct some situations where a write lock on the data in the metadata cache was requested, but only a read lock is necessary. Add routine to find nearest neighbor record < or > to a query key. Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti)
* [svn-r10094] Purpose:Quincey Koziol2005-02-261-2/+7
| | | | | | | | | | | | | | | 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-r10078] Purpose:Quincey Koziol2005-02-241-0/+2
| | | | | | | | | | | | | Bug fix & new feature Description: Fix errors in tracking the total number of records "below" a node. Add feature to find the n'th record in a B-tree Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti)
* [svn-r10077] Purpose:Quincey Koziol2005-02-241-5/+10
| | | | | | | | | | | | | New feature, refactor code Description: Add call to search for a record in a B-tree by key value Refactored some of the existing callbacks to simplify them. Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti)
* [svn-r10020] Purpose:Quincey Koziol2005-02-171-6/+12
| | | | | | | | | | | New feature Description: Add code to iterate over all the records in a v2 B-tree. Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti)
* [svn-r9986] Purpose:Quincey Koziol2005-02-111-4/+4
| | | | | | | | | | | | | | | | | | | 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-r9955] Purpose:Quincey Koziol2005-02-081-5/+4
| | | | | | | | | | | | | | 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 Koziol2005-02-041-2/+5
| | | | | | | | | | | | | 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/+91
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
