Bring r17943 from trunk to 1.8 branch:

context provided to the encode/decode callbacks.
Tested on:
FreeBSD/64 6.3 (liberty)
(h5committested on trunk)
Bring r17891 from trunk to 1.8 branch:
Switch the shared object header messages code to use the refactored
v2 B-tree routines. (this should be the interface that is using them)
Tested on:
FreeBSD/32 6.3 (duty) in debug mode
(h5committested on trunk)
Bring r15676 back from trunk:
Centralize all macros for declaring "magic numbers"/signatures for
objects in the file into src/H5Fprivate.h, so it's easier to know what
values have already been defined, etc.
Tested on:
Mac OS X/32 10.5.5 (amazon)
Too minor to require h5committest
Add small interface to "wrap" a static buffer (usually on the stack), but
still allow for buffers larger than the static buffer to be allocated. This
can eliminate _many_ short-lived buffer allocations in situations where the
buffer is a predictable size (or at least a "very likely" size).
Also, some minor code cleanups, particularly in the SOHM caching code.
Tested on:
Mac OS X/32 10.4.10 (amazon)
Check in "unique, but sharable" optimization to ISOHM code, which
allows object header messages that are only used in one object to remain in
the sole user's header, but migrates messages that are used in more than one
header into the ISOHM heap.
Tested on:
Mac OS X/32 10.4.9 (amazon)
FreeBSD/32 6.2 (duty)
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Roll changes to SOHM v2 B-tree records into format, to get the format
for them stable while I'm working on debugging the actual support for the
"unique, but sharable" feature.
Tested on:
FreeBSD/32 6.2 (duty)
Allow "big" attributes to push attribute storage into "dense" form
immediately, to accomodate storing the attribute. (This is only allowed
in the "latest" version of the format).
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
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.
Add "set_crt_index" and "get_crt_index" methods for the object header
message class.
Unify fractal heap definitions for shared messages and attributes, under
"object header" fractal heap definitions.
Initial code for adding creation order index to object header messages.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Added can_share callback for OH messages. This determines whether the
message is allowed to be shared in the heap (committed and immutable datatypes
can't be).
Fixed a bug in the dense attribute storage that tried to open the shared message
heap when it hadn't been created yet.
Made the test to extend shared dataspace messages a bit more robust.
Refactored the code the searches a shared message list index to be a little
more efficient.
A few other minor changes.
Tested on smirom, kagiso, Windows, and juniper.
Moved SOHM table version out of table encoding and completely into superblock.
This is a file format change.
Added test that extends shared dataspaces. Dynamically allocate arrays in
shared message cache code. Clean up comments.
Tested on windows, kagiso, smirom.
Add support & tests for using shared datatypes with shared & un-shared
attributes. Involves some fairly icky code to make the "copy on write"
paradigm for shared attributes work.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Add support for deleting all the attributes on an object, when they
are dense and possibly shared.
Also, add some testing routines, for better error detection.
Should fix daily test failures also...
Tested on:
FreeBSD/32 6.1 (duty)
Add more tests for checking that writing to shared attributes works
correctly. (Looks like it still has a bug when dense storage is used, which
I'll correct shortly).
Add testing routine to shared message code, to retrieve reference count for
a shared message.
Add fractal heap 'op' callback for efficiently computing the hash value of
an existing encoded message in the shared message fractal heap.
Various minor cleanups and warning placations.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
to make the test pass.
These changes involve changes to the file format of SOHMs, but that's okay
because nobody should have been using SOHMs yet anyway.
Tested on Windows, kagiso, copper, and heping
version and size information into the superblock to eliminate a read when
loading it.
This is a file format change, and hopefully the last one (knock on wood).
Tested on kagiso and Windows (mostly just a SOHM change).
This feature is still in progress; Shared Object Header Messages are not
complete as a feature and are not thoroughly tested. There are still
"TODO" comments in the code (comments with the word "JAMES" in them,
so as not to be confused with other TODO comments).
Hopefully this checkin will reduce the liklihood of conflicts as I finish
implementing this feature.
All current tests pass on juniper, copper (parallel), heping, kagiso, and mir.
