* [svn-r13115] Description:Quincey Koziol2007-01-061-65/+37
| | | | | | | | Allow a heap to be marked for deletion while it is still open and being accessed. (Blocks further opens though). Tested on: FreeBSD/32 6.1 (duty)
* [svn-r13067] Description:Quincey Koziol2006-12-181-6/+115
| | | | | | | | | | | | | | Add [quite] limited ability to update (ie. write) data for objects in fractal heap. Limited to just updating objects in managed heap blocks (i.e. not 'tiny' or 'huge' objects) and must be updated with data of the same length as the object in the heap. Updating objects in compressed heaps does work though [as long as the data isn't 'tiny' or 'huge']. Needed for changing the data value or the name of an attribute that is stored in dense or shared storage. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12823] Description:Quincey Koziol2006-10-291-1/+17
| | | | | | | | | | | | | Add support for compress heap blocks in "managed" heaps. Also, fix bug when the first direct block moves between having a parent and not having one (and vice versa), which occurs when the heap moves between having a direct root block and having an indirect root block. Tested on: FreeBSD 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/C++ & FORTRAN Linux/64 2.4 (mir) w/build-all & 1.6 compat
* [svn-r12699] Description:Quincey Koziol2006-10-021-61/+55
| | | | | | | | | | | 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-r12655] Description:Quincey Koziol2006-09-111-0/+88
| | | | | | | | | | | | Add "op" routine to perform operation on heap object "in situ", to allow for faster operations on dense links during B-tree traversal & lookup. Refactor the "read" routine to use the internal version of the "op" routine, to keep the code duplication as low as possible. Tested on: Mac OS X.4/PPC (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12603] Description:Quincey Koziol2006-08-211-5/+6
| | | | | | | | | | | | | | | | | | | Add a bunch more regression tests: - Verify opening a fractal heap more than once works correctly - Check that 0 & 1-sized object insertions are handled correctly - Check that bad heap IDs are detected when attempting to read an object - Check that doubling tables with different parameter values are working correctly Add some more checks to the code to detect 0-sized object insertions and bad heap IDs for reading. Tested On: FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12598] Description:Quincey Koziol2006-08-191-0/+3
| | | | | | | | | | | | | | - 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 Koziol2006-08-171-9/+33
| | | | | | | | | | | | | | | | | | | | | 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 Koziol2006-08-141-3/+2
| | | | | | | | | | | | | 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 Koziol2006-08-131-21/+3
| | | | | | | | | | 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 Koziol2006-08-101-47/+46
| | | | | | | | | | | | 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-r12551] Description:Quincey Koziol2006-08-071-1/+1
| | | | | | | | | | | 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 Koziol2006-08-071-33/+68
| | | | | | | | | | | 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 Koziol2006-08-071-4/+90
| | | | | | | | | | 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-r12517] Description:Quincey Koziol2006-07-311-3/+14
| | | | | | | | | | | | | | | 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-r12452] Purpose:James Laird2006-07-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | Feature Description: Revised Link APIs. Solution: New link APIs use H5L* H5*create_expand do not create links to the objects created; this must be done manually with H5Llink. Added APIs to link an object given its ID (H5Llink), to copy links (H5Lcopy), and changed creation APIs (H5Lcreate_hard and H5Lcreate_soft) and query API (H5Lget_linkinfo instead of H5Gget_objinfo). All old APIs are still supported in H5Gdeprec.c . Platforms tested: sol, mir, copper Misc. update: Forgot to update MANIFEST and release docs. Will do after checkin.

* [svn-r12161] Purpose:Quincey Koziol2006-03-271-33/+13
| | | | | | | | | | | | | | | | Code checkpoint Description: Checkpoint fractal heap code at a stable point in development. It appears that adding objects to heaps and reading them back out is now working properly (as long as there are no gaps in the heap and no standalone objects are created). Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (chicago) Linux 2.4 (mir) w/64-bit & FORTRAN & C++ Solaris 9 (shanti) w/64-bit

* [svn-r12084] Purpose:Quincey Koziol2006-03-131-7/+16
| | | | | | | | | | | | | | | | Code checkpoint Description: The fractal heap code is reasonably stable and is passing all its current tests, so checkpoint everything with CVS. Also, add "statistics" module for v2 B-trees code, which is only a stub right now. Platforms tested: FreeBSD 4.11 (sleipnir) Mac OSX (amazon) Linux 2.4 (chicago)
* [svn-r12004] Purpose:Quincey Koziol2006-03-041-11/+10
| | | | | | | | | | | | | | | | | New feature & code cleanup Description: Update fractal heap to be able to insert objects into a direct block hanging off the header. Extract "octal dump" code into separate routine so that both the local heaps & fractal heaps can use it. Other code cleanups & support to get this far. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4
