"*buffer_size = j + 1;" was mistakenly taken out by someone. It is necessary to update the new size. I
put it back and made 2 test cases for integer and float to verify the correct dataset size.
Tested on jam, heiwa, and amani.
Checked in fix for failure in shape same tests that appeared after
Quincy's recent massage of the test code. The problem was a race
condition created when Quincey re-worked the code selecting either
collective or independant I/O.
Previously, when independant I/O was selected in the test, I had
used H5Pset_dxpl_mpio() and H5Pset_dxpl_mpio_collective_opt() to
select collective semantics with independant I/O going on under
the hood. Quincey modified this to call H5Pset_dxpl_mpio() when
collective I/O was selected, and do nothing in the independant I/O
case. As a result, processes were able to race ahead and
modify the initial values of the data set before some processes
had verified that the initialization was correct.
Solved the problem by adding barriers, and making all barriers
dependant on independant I/O being selected.
Tested parallel on amani and phoenix. h5committested.
a) Add comments to test_4() in test/external.c about the name "/ link".
b) Fix one memory leak in src/H5Lexternal.c: free memory pointed to by tmp_env_prefix for HDF5_EXT_PREFIX case.
3. Made changes for bug #1930 as in rev #19783, #19781 in trunk.
4. Made corresponding CMake changes as in rev #19782 in trunk.
Change to skip copying when a dataset is not allocated.
Merged from hdf5 trunk r19818.

Add "--enable-unsupported" configure flag.
Description
The "--enable-unsupported" configure flag allows a user to
prevent configure from failing due to the use of incompatible
options, such as c++ with parallel.
Specifying --enable-unsupported will bypass all of configure's
checks for incompatible and unsupported combinations of flags.
There are no guarantees that the library will be configured
in any sort of working condition, but that's the risk of
using the --enable-unsupported flag.
I've changed all default error messages related to unsupported
option combinations to indicate that using --enable-unsupported
will allow configure to complete without error.
Tested:
by hand on jam, tested all unsupported configure option
combinations with and without the new flag, making sure
the flag allows configure to finish without error.
(h5committest wouldn't do any good here; it won't test
the new option, and since we're enabling unsupported
combinations, failures are likely to occur in build or
tests with --enable-unsupported turned on anyways.
That's why they're unsupported!)
Add additional error checking to catch erroneous user input.
Description:
Attempting to retrieve a links's name by index in the case
where the link is external and the file that the object is
located in doesn't exist was causing a segmentation fault
(in production) and an assertion failure (in debug).
The segfault wasn't occuring until the metadata accumulator
attempted a write, so I've added error checking higher in
the pipeline in H5O_protect (where there was previously just
an assert) to catch this. I've also added additional asserts
in the H5F layer where there were none.
Additionally, I added another case to the links.c test to
test that this fails gracefully instead of segfaulting or
asserting out.
Tested:
h5committest and gandalf (mac os x)
The parallel test ran out of memory because 32bit binary default to use
less memory. Changed RUNPARALLEL to use larger memory (LDR_CNTRL=MAXDATA=0x2000
0000@DSA).
Tested: BP parallel.
Fix compile error for Windows from previous checkin r19758.
Description:
Previous log:
Improve h5diff performance.
The following changes for improving h5diff performance:
1) use HDmemcmp() before comparing each elements
(memcmp() is very fast at both linew and jam)
2) replace the expensive H5Tequals() calls
3) retrieve datatype information at dataset level not each element level
for compound datasets
Tested:
jam (linux32-LE), Windows

Fixed Bug# 1979 Output from h5ls -rdlS on nested compound datatypes is
difficult to parse.
Description:
Update to add curly brackets for the nested compound members, when
S (--simple) option is used with -l (--label), so user can tell
which members blong to which compound type.

Bring r19743-19744 from trunk to 1.8 branch:
Correct tests to use native datatypes consistently, and also to use
"normal" methods for performing collective I/O. Also, minor cleanups for
zeroing out buffers, etc.
Tested on:
FreeBSD/32 6.3 (duty) w/debug
(h5committested on trunk)

Bring r19725 from trunk to 1.8 branch:
Add a little bit of extra info to the output from h5debug when
displaying global heaps, and make it dump the file's superblock again when
an address is not given on the command line.
Tested on:
FreeBSD/32 6.3 (duty) w/debug

Bug fix for failure in the round robin metadata write ojbect header
metadata confusion test that appeared after Albert modified the test.
Cursory commit test. No test on Abe as that system is down, the
fix is very minor, and it seems to work in the 1.8.6 branch
Fixed h5diff to handle variable-length strings in a compound dataset
correctly. Also variable-length string array in a compound dataset.
Bug #1989.
Description:
Garbage values were displayed when h5diff compared variable-length
strings (or string array) in a compound type dataset.

double to (unsigned) long and from (unsigned) long to long double. I added tests in configure.in
to detect these algorithms. Before I can figure out them, I disable the tests in dt_arith.c.
Tested on jam, heiwa, amani, IBM Power6 Linux machine in Holland (huygens.sara.nl).
