* [svn-r12699] Description:Quincey Koziol2006-10-021-3/+62
| | | | | | | | | | | Fix problems with opening a fractal heap multiple times, from different file handles. Tested on: FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/FORTRAN & C++ Linux/64 2.4 (mir) w/enable-v1.6 Mac OS/32 10.4.8 (amazon)
* [svn-r12610] Description:Quincey Koziol2006-08-221-0/+1
| | | | | | | | | | | | | | Add support for checksumming fractal heaps. This is always enabled for the heap header and indirect blocks (as they are "pure" metadata) and is optional for direct blocks, since they may be used for "raw" data. Also, rearrange direct block routines in H5HFcache.c to be in a more sensible location in the file. (probably should have been a separate checkin, since the diffs are mostly useless for this checkin... *sigh*) Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12598] Description:Quincey Koziol2006-08-191-7/+9
| | | | | | | | | | | | | | - Migrate "direct block location" routine from H5HFman.c to H5HFdblock.c, which is a more appropriate location - Optimize performance of heap code by taking advantage of pinned indirect blocks and use them without putting a metadata cache protect/unprotect pair around them. - Other minor compiler warning cleanups and optimizations... Tested On: FreeBSD/32 4.11 (sleipnir) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12592] Description:Quincey Koziol2006-08-171-21/+63
| | | | | | | | | | | | | | | | | | | | | Several changes, all mooshed together: - Add support for "tiny" objects - which can be stored in the heap ID itself, instead of in the heap data blocks. - Flesh out support for compressed direct blocks, but comment it out until John's got some metadata cache changes in place to support it. - Add support for applying I/O pipeline filters to 'huge' objects - Refactor 'huge' object code to store information for 'huge' objects directly in the heap ID, when there are I/O pipeline filters applied to the heap (and the heap ID is large enough to hold the information) - Update h5debug tool to correctly handle 'huge' & 'tiny' objects. - Misc. other code cleanups, etc. Tested on: FreeBSD/32 4.11 (sleipnir) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12575] Description:Quincey Koziol2006-08-141-11/+105
| | | | | | | | | | | | | Allow the heap ID length to be chosen at heap creation time, to allow for making heap IDs long enough to directly embed the file offset & length of 'huge' objects in the heap ID (which allows them to be retrieved directly from disk, instead of requiring them to be looked up in the B-tree that tracks 'huge' objects) Tested on: FreeBSD/32 4.11 (sleipnir) Linux/64 2.4 (mir) Solaris/64 9 (shanti)
* [svn-r12572] Description:Quincey Koziol2006-08-131-25/+50
| | | | | | | | | | Refactor new heap's header creation code to be all in the H5HFhdr.c module. Tested on: FreeBSD 4.11 (sleipnir) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12562] Description:Quincey Koziol2006-08-101-2/+6
| | | | | | | | | | | | Initial revision to add support for "huge" objects in the heap (which are actually stored directly in the file, but are tracked with v2 B-tree that is accessed through heap header). Testing: FreeBSD 4.11 (sleipnir) Linux/64 2.4 (mir) Linux/32 2.4 (heping) Mac OS X.4 (amazon)
* [svn-r12552] Description:Quincey Koziol2006-08-071-5/+3
| | | | | | | | | | | More tweaks on fractal heap statistics, to better separate information about managed objects from information about "huge" objects. Also, clean up some compiler warnings, etc. on 64-bit platforms & Windows. Platforms tested: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago)
* [svn-r12551] Description:Quincey Koziol2006-08-071-6/+8
| | | | | | | | | | | Refactor fields in heap header to clean out information from dropped features and also group related fields together more nicely. Add fields to heap header for storing information about "huge" objects. Platforms tested: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago)
* [svn-r12550] Description:Quincey Koziol2006-08-071-1/+1
| | | | | | | | | | | Refactor fractal heap IDs to include "flag byte" as part of the ID. This byte will be used for the heap ID format version as well as flags to indicate whether the heap object is a "tiny"/normal/"huge" object (with storage mechanisms optimized for each type of object). Platforms tested: Linux/32 2.4 (chicago) Too minor to require h5committest
* [svn-r12549] Description:Quincey Koziol2006-08-071-1/+1
| | | | | | | | | | Add support for entire heap deletion. Platforms tested: FreeBSD 4.11 (sleipnir) Linux/32 2.4 (chicago) Linux/64 2.4 (mir) Mac OS X (amazon)
* [svn-r12525] Description:Quincey Koziol2006-08-021-3/+0
| | | | | | | | | | | Refactored free space manager to use metadata cache for serialized free space sections. This speeds up the fractal heap test considerably... Tested: FreeBSD 4.11 (sleipnir) Linux 2.4/32 (chicago) Linux 2.4/64 (mir) Mac OS X (amazon)
* [svn-r12517] Description:Quincey Koziol2006-07-311-10/+48
| | | | | | | | | | | | | | | Fix the last scattered bunch of problems with the object deletion code, which appears to be completely working now (for objects that are stored within heap blocks - standalone objects aren't implemented yet). Also, re-work the regression test to speed up some of the existing tests and add in 100-200 more combinations of tests - overall, its probably even slower than it was... :-/ Tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (chicago) Mac OS X (amazon)
* [svn-r12491] Description:Quincey Koziol2006-07-221-174/+29

| | | | | | | | | | | | | | | | | Code checkpoint Description: Add in more new features for the fractal heap code, mostly bringing in more ability for deleting objects (which isn't completely working yet). Also, checkpoint free space manager code, which is essentially complete (although it needs some more work after the metadata cache has some additional features) Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (chicago) h5committest
