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!!!

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.... :-)

Code cleanup
Description:
Trim trailing whitespace, which is making 'diff'ing the two branches
difficult.
Solution:
Ran this script in each directory:
foreach f (*.[ch] *.cpp)
sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f
end

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".
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel & fphdf5
FreeBSD 4.10 (sleipnir) w/threadsafe
FreeBSD 4.10 (sleipnir) w/backward compatibility
Solaris 2.7 (arabica) w/"purify options"
Solaris 2.8 (sol) w/FORTRAN & C++
AIX 5.x (copper) w/parallel & FORTRAN

Code cleanup
Description:
Tweak recent "forward compatibility" changes to the H5E* API (which allowed
for the old H5E API functions to remain unchanged) by allowing for the error
stack callback function (H5E_auto_t) to also remain unchanged from the 1.6
branch. This required changing the H5E{get|set}_auto routines to have the
old style H5E_auto_t type (which didn't have a stack ID parameter) and the new
H5E{get|set}_auto_stack routines to have a newer "H5E_auto_stack_t" type (which
has a stack ID parameter). This should make the H5E API changes as forwardly
compatible as possible.
One side-affect of this change was that it was impossible to determine if
the current auto error callback was the old style (H5E_auto_t) or the new style
(H5E_auto_stack_t) of callback, so a new API function (H5Eauto_is_stack) was
adde to query this.

Bug fix

New feature for developers.
Description:
Added "function stack" tracing to library. This allows developers (there
is no public API) to call H5FS_print within the library and get a listing
of the functions traversed to reach that point in the library. Eventually,
I may add support for reporting the parameters to each function also...
Mainly for debugging parallel I/O programs, but I think it will come in
handy in other cases also.
The function stack tracking is controlled with a configure switch:
--enable-funcstack, which defaults to enabled currently. When we branch
for 1.6, we should change the default setting on the branch to be disabled.
Also, added a destructor to the thread-specific keys when thread-safety is
turned on in the library. Otherwise, they were leaking memory and causing
difficult to debug errors in threaded programs (like the test/ttsafe test).
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir) w/thread-safety enabled.
Misc. update:
Updated MANIFEST with new files added (src/H5FS.c & src/H5FDprivate.h)
Update release_docs/RELEASE with thread-safety bug fix.

Update test
Description:
Some of the performance improvements changed the errors that are reported
for creating a duplicated dataset in a file, causing this test's hard-coded
errors to check for to fail.

Updated error stack reported for dataset creation failure.

Purpose:
Bug Fix
Description:
The table of error messages was updated in H5E.c. The change wasn't
reflected in this test because, sadly, we use hardcoded numerical
values for the "error" we want to check for and not the symbols.
Solution:
Bumped up the error number from 32 to 34 to coincide with the error
we expect.

Linux

file (they
were only creating one for all of them). Also changed so that, if they
got an error, it actually specifies that the tests failed on the screen
instead of succeeded ;-)

that all HDF5 API functions are protected by a mutex lock. Basically,
serialized all API calls. To use it, use
configure --enable-threadsafe --with-pthread
