1. For enum type, members shouldn't be defined yet.
2. H5T_ORDER_NONE only works for reference and fixed-length

3. For opaque type, the order will be ignored.
4. For compound type, all restrictions above apply to the

I'll change H5Tget_order and do another commit.
There is no change to configure.in, config, and Makefile.am. There is some property change for

Description:
honest3 v1.8 failed in parallel test. It got stuck in the same
testpar/testphdf5 subtest (cbhsssdrpio). This is an old problem.
Upon closer inspection, the testphdf5, when terminated, had clocked
up 1hr 9min 46 sec wall clock time. Honest1 system also sent a message
that an mpi process has used up 30+ CPU minutes which exceeded their login
node cpu time limit and they killed the process. I also did a hand-run
of testphdf5. All subtests before cbhsssdrpio completed in a few minutes.
Therefore, it is safe to say the majority of the 70 minutes of wall clock
time are spent in the sub-test cbhsssdrpio. It also used up lots of CPU
time. cbhsssdrpio is likely infinite looping.
Since MPI application is prone to infinite looping due to message deadlock,
the testphdf5 has a built-in protection to give each subtest at most 20 minutes
of wall-clock time to run. When the 20 minutes wall-clock time is exceeded,
the testphdf5 will attempt to terminate itself. This prevents unnecessary
CPU time consumption in infinite looping.
But that clock limit was changed to 30 and then 60 minutes. I should have
but failed to, noticed the change mentioned by Quincey. IMO, 20 wall clock
time is more than sufficient for each subtest of testphdf5 to complete.
If a subtest takes longer than 20 minutes, it is likely infinite looping.
Giving it more time will not help.
If a subtest of testphdf5 takes more than 20 minutes, it should be broken
down to small tests that will finish way under 20 minutes so that it is
much easier to see progress and identify any deadlock problems.
In view of this, I am changing the testphdf5 time limit back to 20 minutes.
This will at least stop the CPU TIME exceeding limits and annoying the
system administrators.
Maybe there could be a provision, such as environment variable like
$HDF5_ALARM_SECOND to modify the alarm duration on individual execution.
Even so, that should be used temporary to see if an execution just needs
a little more time.
Tested: just eyeballed as the change is trivia.
herr_t. To minimize the change of the library's behavior, in the function
H5Z_prelude_callback of H5Z.c, if the return value of can_apply is FALSE and
the filter is MANDATE, this function returns a FAILURE. If the return value is FALSE
but the filter is OPTIONAL, this function returns a SUCCEED. During the IO, the filter
will fail and return a size of zero. But the pipeline will skip this filter.
Tested the same change for 1.8 on jam, linew, and amani. Tested on jam with szip.
Description:
test/big incorrectly determined not able to write files larger than 2GB and
skipped the SEC2 and STDIO driver tests. The reason was because it was using
off_t while the SEC2 driver is using lseek64 which expects off64_t type.
Solution:
Created a new HDoff_t which is set to off_t or off64_t or other appropriate
type depending on which of lseek or lseek64 is available. Changed SEC2 file
driver and the big test to use this common definition.
Tested:
In BP (AIX), using --enable and --disable-largefile, for both 32 and 64 bits
modes. Did not do h5committest because: 1. the error was exposed in the remote
BP machine; 2. the change is trivial.
Note that STDIO driver failed when --disable-largefile is used. That is an
error in the STDIO driver code that is being fixed.
Bring revisions from Coverity branch back to trunk:

Coverity #449 - Line 1560 called function H5O_chunk_protect for 2 pointers to allocate. But when there's failure on the second one, the first wasn't freed

r19061:
Fix coverity item 139. Fixed incorrect condition for freeing buffer on error.
Fix coverity items 20 and 21. Removed unused NTESTS facility from dtypes.c.
Cleanup in H5Shyper.c.

Fix coverity item 454. Check to see if allocation of buf failed in
H5D_fill_refill_vl.
Fix coverity items 455-457. Initilize hid_t's to -1, check their value before
attempting to close them, and check if the close failed.

Description:
A bug introduced in 1.8.5 causes local heap data blocks to be mis-aligned when
sizeof_offsets + 2*sizeof_lengths is not a multiple of 8. In this case, the
address of the data block as stored in the heap prefix is aligned but the actual
data block is not. This causes files created with these sizes to be corrupted,
and prevents uncorrupted files with these sizes to be unreadable. Modified
local heap code to account for alignment.

Commit metadata tagging framework.
Description:
This check-in contains a new framework whose goal is to apply
a tag value to each new entry in the metadata cache as it is created.
This tag value is such that it relates each piece of metadata to the
HDF5 object that it belongs to (dataset, group, et cetera).
This changeset includes the framework that applies the tags as
well as a suite of tests to verify correct tag application, though does
not yet make use of the tag values to flush/evict individual objects.
Please refer to the "flush/evict individual objects" RFC for further
discussion of these changes.

Problem: some launching command like yod (and sometimes mpirun), do not pass
back the exit code of the executables back to the shell. It always returns 0
if it can launch the executable. This cause tests that expect non-zero exit
code to fail incorrectly.
Short term Solution:
Added the feature that if $RUNSERIAL_NOEXITCODE is defined, do not
test conditions that rely on non-zero exit code.
Tests:
dove-linux using RUNSERIAL=thgyod to see the failures and using
$RUNSERIAL_NOEXITCODE=yes to bypass the errors.
Also h5committested.
This also affected the use of the #include <winsock.h> needed by gethostname. The new include: winsock2.h has been added to h5private.h and either removed or updated in the other files.

fill values.
Description:
Previously, H5D_chunk_allocate would, if a dataset were filtered and had a non-default VL fill value, allocate a new buffer for every chunk. Changed
H5D_chunk_allocate to reuse the existing buffer if possible. Also other
miscellaneous cleanup.
Tested: jam, linew, amani (h5committest)
Description:
Previously, it was possible for a chunk to be flushed due to chunk operations in
the callback from H5B_iterate in H5D_chunk_prune_by_extent. Because flushing
the chunk can force it to be reallocated if it is filtered, this can change the
contents of the chunk b-tree in the middle of H5B_iterate. Because H5B_iterate
uses a locally cached copy of the b-tree, this causes subsequent operations
to be passed incorrect data. Rewrote H5D_chunk_prune_by_extent to avoid
H5B_iterate entirely.
Also fixed a bug in the dataset expand algorithm that could cause extra chunks
to be created.
Tested: jam, linew, smirom (h5committest)

Improve configure's large-file support control.
Description:
Modified configure to now attempt to add defines necessary for
supporting largefiles on all systems, instead of solely on linux. This
is in response to user requests to enable largefile support on Solaris
by default, as well as to give extra control on AIX (instead of just
jamming the necessary flag into the config files).
The old --enable-linux-lfs flag has been removed in favor of the
--enable-largefile flag (enabled by default), which can be used on all
platforms.
On systems where large files cannot be supported in this manner,
configure will report as such.

Autotool Upgrade / Libtool Bug Fix
Description:
Updated autotools referenced in bin/reconfigure as follows:
Autoconf 2.64 --> Autoconf 2.65
Automake 1.11 --> Automake 1.11.1
Libtool 2.2.6a --> Libtool 2.2.6b-mcg
The referenced libtool version is a custom version of 2.2.6b. It
has been tweaked to fix a bug in libtool that occurs
when using PGI 10.0 compilers. A check incorrectly categorizes
the C++ compiler as version 1.0 instead of 10.0, and the link
line is subsequently set up incorrectly and fails to compile.
A patch has been made available and will be included in the next
release of libtool, but in the meantime I've applied the patch to a custom
installation as indicated above. This bin/reconfigure now references
the custom installation, and the resulting configure script will correctly
categorize the PGI 10.0 C++ compiler.
Ran bin/reconfigure to regenerate configure and makefiles.
Tested:
jam and amani with PGI 10.0 compilers.

Description:
Attempting to copy an object with NULL references (all bytes zero) with the
H5O_COPY_EXPAND_REFERENCE_FLAG flag set would cause a failure or an assertion
(depending on whether it was in debug mode). Changed copy routine to detect
NULL references (object and region) and avoid attempting to expand the reference
in this case.
