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.
Fix object header message code to respect the "do not share" flag, so
that committed datatypes used in attributes are handled properly.
Add more tests for atttributes, checking that they handle shared
attributes in compact & dense storage w/committed datatypes.
Tested on:
FreeBSD/32 6.1 (duty)
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 first pass of "dense" attribute storage to objects. Lots of parts of
this are stubbed out, but all the tests are passing and I'll work on the corner
cases soon.
Eliminated several unused parameters from object header message callback
routines.
Other, miscellaneous code cleanups, etc. (and probably some things I've
forgotten about... :-)

Linux/64 2.4 (mir)
Propagate object creation properties up into group, dataset and named

existing objects in a file.
Also, add H5Tget_create_plist() API routine, to allow named datatype
property lists to be retrieved for named datatypes.

Refactor internal code that retrieves the object's type to use the new
H5O_type_t (which only definitions for object types, instead of links as well)
instead of the older H5G_obj_t (which included links, etc.)
Tested on:

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.
Add the "use the latest version of the format" support to datatype
messages. And a regression test to check that it's working.
Also, found that we have been over-allocating space for compound datatype
messages (when they have array datatypes or can use the latest version of the
format) and trimmed the size back.
Clean up datatype & dataspace encode/decode routines by having them
allocate & release "fake" file structures, which gets them out of needing to
"know" about the internals of file structures.
Other minor whitespace/formatting cleanups, etc.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
File format is not stable, don't keep files produced!
Description:
First stage of checkins modifying the format of groups to support creation
order. Implement "dense" storage for links in groups.
Try to clarify some of the symbols for the H5L API.
Add the H5Pset_latest_format() flag for FAPLs, to choose to use the newest
file format options (including "dense" link storage in groups)
Add the H5Pset_track_creation_order() flag for GCPLs, to enable creation
order tracking in groups (although no index on creation order yet).
Remove --enable-group-revision configure flag, as file format issues are
now handled in a backwardly/forwardly compatible way.
Clean up lots of compiler warnings and other minor formatting issues.
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 compa
Mac OSX/32 10.4.8 (amazon)
AIX 5.3 (copper) w/parallel & FORTRAN
Object header locations (H5O_loc_t's) can now "hold open" a file and
decrement its open object count when they close. This means that
locations (H5O_loc_t's and H5G_loc_t's) should always be freed.
Added more thorough tests to ensure that external files are closed.
Users can create external links using H5L_create_external(). These links
point to an object in another HDF5 file. Users can alter the behavior of
external links or create new kinds of links by registering callbacks
using the H5L interface.
Added tests, tools support, etc.
Also a number of other, minor changes have been made (some restructuring of
the H5L interface, for instance).
Additional documentation and examples are forthcoming.
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.
"Hide" file format changes (for now)
Description:
Add ifdef's (controlled by the --enable-group-revision configure flag)
to disable group revision changes to the file format, in order to allow alpha
release to go ahead without releasing an unsupported version into the wild.

Bug fix
Description:
Retrieving an object's name could fail (in various ways) under certain
circumstances (mostly having to do with mounted files).
Solution:
Re-write & simplify "get object name" code to fix error in a better way
than adding yet another hack to the previous pile of hacks... :-)
Platforms tested:

Configure feature
Description:
Added 'make trace' target.
Solution:
Added tracing to 1.7. This was done automatically in 1.6, but left out
of 1.7 until now (oops!).
Tracing in 1.7 only happens manually, when the user types 'make trace.'
Tracing automatically requires more framework than it's worth.
I also fixed a couple of tracing bugs and ran trace.
Platforms tested:
mir, sleipnir, modi4
Misc. update:
New feature
Description:
Check in baseline for compact group revisions, which radically revises the
source code for managing groups and object headers.
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
This initiates the "unstable" phase of the 1.7.x branch, leading up
to the 1.8.0 release. Please test this code, but do _NOT_ keep files created
with it - the format will change again before the release and you will not
be able to read your old files!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
Solution:
There's too many changes to really describe them all, but some of them
include:
- Stop abusing the H5G_entry_t structure and split it into two separate
structures for non-symbol table node use within the library: H5O_loc_t
for object locations in a file and H5G_name_t to store the path to
an opened object. H5G_entry_t is now only used for storing symbol
table entries on disk.
- Retire H5G_namei() in favor of a more general mechanism for traversing
group paths and issuing callbacks on objects located. This gets us out
of the business of hacking H5G_namei() for new features, generally.
- Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t
- Lots more...
Platforms tested:
h5committested and maybe another dozen configurations.... :-)
Bug fix
Description:
Fix "double root open" bug and apply same fix to datasets & named datatypes.
Also fix bug in symbol table entry lookup code that would "transfer" an
object from one file handle to another file handle when the two file handles
were opened on the same actual file.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Code cleanup
Description:
Merge back changes from "compact group" work that improve the
infrastructure of the library and may impact others. In this round of
merging, that includes:
- Move datatype allocation into single internal routine, instead of
duplicated code that was spread out in a dozen or so places.
- Clean up guts of object header routines (H5O_*) to allow for some of
the fancieroperations that need to be performed on groups, along with
some general improvements.
- Added a new error code
- Some minor cleanups in other code....

Code cleanup
Description:
Trim trailing whitespace, which is making 'diff'ing the two branches

Description: Removed PABLO from the source
Solution:
Platforms tested: arabica with 64-bit, copper with parallel,
heping with GNU C and C++ and PGI fortran (but
I disabled hl, there is some weird problem only
on heping: F9XMODFLAG is not
propagated to the Makefile files
Misc. update:
Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".

Description:
Improve ADF/CGNS benchmark by reducing the number of internal attribute
copies made during creations, opens and writes.
Added new H5O_iterate() routine for iterating through messages of a certain

have multiple instances in the object header).
Cross-pollinated various minor code cleanups to reduce diffs between
branches.

Purpose:
Feature
Description:
Datatypes and groups now use H5FO "file object" code that was previously
only used by datasets. These objects will hold a file open if the file
is closed but they have not yet been closed. If these objects are unlinked
then relinked, they will not be destroyed. If they are opened twice (even
by two different names), both IDs will "see" changes made to the object
using the other ID.
When an object is opened using two different names (e.g., if a dataset was
opened under one name, then mounted and opened under its new name), calling
H5Iget_name() on a given hid_t will return the name used to open that hid_t,
not the current name of the object (this is a feature, and a change from the
previous behavior of datasets).
Solution:
Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's,
and H5G_t's into a "shared" struct and a private struct. The shared structs
(H5D_shared_t, etc.) hold the object's information and are used by all IDs
that point to a given object in the file. The private structs are pointed
to by the hid_t and contain the object's group entry information (including its
name) and a pointer to the shared struct for that object.
This changed the naming of structs throughout the library (e.g., datatype->size
is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.
Platforms tested:

too minor to require h5committest
Code cleanup & minor optimization
Description:
Re-work the way interface initialization routines are specified in the
library to avoid the overhead of checking for them in routines where there is
no interface initialization routine. This cleans up warnings with gcc 3.4,
reduces the library binary size a bit (about 2-3%) and should speedup the
library's execution slightly.
Platforms tested:

h5committest
Code cleanup
Description:
Clean up compiler warnings, especially the 'FUNC' variable not used which
comes out in production mode.
Solution:
Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API
functions which don't need the 'FUNC' variable defined. (This will be _so_
much easier when C99 is standard on all our supposed platforms, since it has a
__FUNC__ macro... )
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor for h5committest (although there were lots of files changed, the
change was minor in each one)
Bug fixes and code cleanup
Description:
Lots of changes here:
- Fixed bug #691 - when shared datatypes are used in attributes they
are incorrectly copied into the attribute instead of referring
the the named datatype in the file. This required bumping the
version of the attribute message. The new version of the attribute
message is only written out when a shared datatype is used in
the attribute. [Also, this format change made the size of the
attribute smaller.]
- Added information to attribute debugging routine so that shared
datatypes are displayed correctly with the h5debug tool.
- Refactored the H5O* routines to extract code that was common to
several routines into subroutines to call.
- Added 'link' method for H5O message sub-classes, which increments
the link count on shared objects when a message is created which
shares them.
- Corrected [unreported] bug where the link count was not being
decremented on the shared object when a object header message
with a reference to that object was deleted from the file.
- Reduced size of shared message from 49 bytes (which was incorrect
anyway and should have been 48 bytes) to 10 bytes, which required
bumping the version of "shared" messages.
- Refactored some of the shared datatype routines to allow for easier
queries of "committedness" internally to the library and also
added routine to easily increment/decrement the reference count of
a shared datatype.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Bug fix.
Description:
When a duplicate object was attempted to be created, the library would
leak file memory and object references in the file, potentially causing an
infinite loop when shutting the library down.

Platforms tested: h5committest
Code cleanup
Description:
Clean up miscellaneous warnings which have crept into the code.
Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD.
Adjust gcc compiler flags to be more concise for production mode.
Refactor the H5O code so that there is a stronger boundary between code
in the H5O package and code in the library which just calls H5O routines.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)

Misc. update:
Update MANIFEST if you add or remove any file.
Code cleanup.
Description:
Break up the ~9350 line H5T.c module into smaller pieces, which contain
code for a particular feature or support for a datatype class.
This should make the "main" H5T code (still in H5T.c) easier to support,
as well as removing some of the "minor" routines from the user applications
which don't use them (my rough estimates show about 4% reduction (~30K on
a FreeBSD machine) in optimized, staticly-linked binaries for very simple
programs)
Platforms tested:
