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.
Migrate more object header routines to use the H5O_msg_ prefix and put
them into the src/H5Omessage.c code module.
Tested on:
Mac OS X/32 10.4.8 (amazon)
FreeBSD/32 4.11 (sleipnir)
Linux/32 2.4 (heping)
AIX/32 5.? (copper)
Reduce memory usage for common cases of I/O pipeline filter memory usage.
Also, clean up some more code...
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
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)
Fix failure in "remove bogus ID" test which turned up randomly (due to
random "bogus" IDs being used in test :-) by adding some more defensive
checks on object IDs to the object removal code.
Tested on:
FreeBSD 4.11 (sleipnir)
Linux/64 2.4 (mir)
Solaris/64 (shanti)
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)
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)
Refactored object deletion code for fractal heap to fix scaling problems.
Passing all previous tests again now.
Tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
Mac OS X (amazon)
Code checkpoint
Description:
Revise fractal heap code to support deletions in up to 2nd level deep
indirect blocks. Needs some revisions to support deeper indirect blocks...
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
h5committest
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
Code checkpoint
Description:
Update fractal heap code to allow objects to be deleted
Fix bugs in fractal heap object insertion
Improve free space manager code to allow sections to be merged and
shrink the container
Another try at making the Windows compilers happy...
Platforms tested:
FreeBSD 4.11 (sleipnir)
Mac OS X.4/PPC (amazon)
Linux 2.4 (chicago & heping)
Solaris 2.9 (shanti)
AIX 5.? (copper) w/parallel
Code checkpoint
Description:
Checkpoint fractal heap improvements, as well as move the free space
manager code that it's using into a separate package.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4/64 (mir) w/C++ & FORTRAN
Linux 2.4/32 (heping)
Solaris 2.9 (shanti)
AIX 5.? (copper) w/FORTRAN & parallel
Code checkpoint
Description:
More progress on fractal heap, can now re-open an existing heap, although
the free space algorithm still needs work.
Also, use the new "pinned entry" metadata cache code.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (heping)
Solaris 9 (shanti)
Linux 2.4/64 (mir)
Code checkpoint
Description:
Add in more fractal heap support for odd allocation patterns (entries that
are too large for various block sizes, etc.)
Broke out fractal heap code into more source code modules.
Refactored fractal heap test to make it more understandable and
maintainable for the long term.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (heping)
Linux 2.4/64 (mir)
Solaris 2.9 (shanti)
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
Code checkpoint
Description:
Checkpoint fractal heap changes - mostly internal changes to better
handle more direct blocks from root indirect block.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
Mac OS X (amazon)
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)
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
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)
New feature
Description:
Check in initial "fractal heap" code, for supporting the group redesign.
Also, remove some remnants of the segmented heap/block tracker/B+tree code
which I didn't find during the last pass.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Mac OSX (amazon)
Linux 2.4
