Bug fix.
Description:
Sometimes the parallel prefix is given in the form of nfs:/mnt/pfs which
if given to a non-MPIO VFD like the default H5Fcreate, it would fail.
Called h5_rmprefix which would return the non-prefix component
part of the file name which would be okay for the default H5Fcreate and
such.
Platforms tested:
Tested in heping parallel.

Feature
(Code and tests are done by Christian. I just committed the code.)
Description:
Rewrote the purpose of this test. Now it tests these three cases,
/*
* Test following possible scenarios,
* Case 1:
* Sequential create a file and dataset with H5D_ALLOC_TIME_EARLY and large
* size, no write, close, reopen in parallel, read to verify all return
* the fill value.
* Case 2:
* Sequential create a file and dataset with H5D_ALLOC_TIME_EARLY but small
* size, no write, close, reopen in parallel, extend to large size, then close,
* then reopen in parallel and read to verify all return the fill value.
* Case 3:
* Sequential create a file and dataset with H5D_ALLOC_TIME_EARLY and large
* size, write just a small part of the dataset (second to the last), close,
* then reopen in parallel, read to verify all return the fill value except
* those small portion that has been written. Without closing it, writes
* all parts of the dataset in a interleave pattern, close it, and reopen
* it, read to verify all data are as written.
*/
Platforms tested:
Tested in copper, tg-ncsa and heping, all in parallel mode.

1) Check in potential fix to unreproduceable bug in t_cache observed on
Cobalt
2) Check in code supporting added pinned entry features in the metadata
cache.
Description:
1) Elena encountered a bug in t_cache when running on Cobalt. On
investigation I found a potential race condition in t_cache that
could explain her observation.
2) Quincey requested additions to the metadata cache allowing renaming
of pinned entryies, and marking of pinned or protected entries as
dirty.
Solution:
1) Modified t_cache.c to prevent the potential race condition. Elena
was unable to reproduce the bug on Cobalt, so we don't know if my
fix actually addressed the problem.
2) Added code supporting the requested functions. The changes were
relatively trivial, but required substantial new test code.
Platforms tested:
h5committest, serial test on heping, parallel test on phoenix.

Bug fix.
Description:
The ${TR}, though avoid the error, is inconvenient. It is needed
because configure.in use the char range in the style of 'a-z'.
The other style of '[a-z]' is more commonly accepted by all tr
but autoconf tends to strip away [], making the syntax rather
clumsy.
Solution:
Learned from autoconf that it avoids the use of character range
by just spell all the letters out. Changed our tr commands to
use those variables defined by autoconf. Also removed the
definition of ${TR} since it will cause inconsistancy when
autoconf also use plain 'tr' in its generated code.
The Makefile.in are changed because the elimination of ${TR} from
configure triggered its removal from all Makefil.in. That is okay
because ${TR} is not used at all in Makefile.
Platforms tested:
h5committested. (sol failed to connected). also tested in shanti
using both /usr/ucb/tr and /bin/tr (the bad one before.)
Misc. update:
Updated both INSTALL and RELEASE files.

Bug fix
Description:
Fix two test bugs:
1) Unitialized variable bug in test of H5C_get_entry_status()
(in test/cache.c)
2) Incorrect initialization of constant in t_cache when running
with MPE. (in testpar/t_cache.c)
Solution:
1) Don't test uninitialize variable.
2) Correct initialzation of constant in MPE case.
Platforms tested:
Tested on Heping and Copper.

Code cleanup/feature twist
Description:
Adjust recent H5AC routines to take H5F_t pointers instead of H5C_t
pointers, to match the rest of the H5AC routines.
This change propagated into a few of the tests, which also had some
compiler warnings cleaned up...

Add pinned entry capability to cache.
Description:
For frequently accessed cache entries, the protect/unprotect overhead
is sometimes a bottleneck.
Solution:
Allow entries to be pinned in the cache. Pinned entries can't be
evicted, but can be flushed or modified.
Platforms tested:

Several bug fixes
Description:
Added config file for Cray X1 (previous file was misnamed)
Simplified some code in hyperslab.c test that seemed to have been
confusing compiler on Cray X1.
Fixed typo in config/commence.am
Cleaned up hl/src/Makefile.am
Solution:
All four fixes should be straightforward. The failure on Cray was
very difficult to debug, but involved arithmetic errors.
This change seems to fix it.
Platforms tested:
heping, copper, sol, some Cray X1 (more testing when system comes back up)

Adding parallel tests for optional collective chunk APIs
Description:
Three new APIs
"H5Pset_dxpl_mpio_chunk_opt_ratio
H5Pset_dxpl_mpio_chunk_opt_num
H5Pset_dxpl_mpio_chunk_opt"
for optional optimization choices from users
have been added to the libraries.
This check-in adds six tests to verify the funcationality and correctedness
of these APIs.
These tests need to be verified with 3 or more processors and with MPI-IO driver only.
Solution:
Using H5Pinsert, H5Pget, H5Pset to verify that the library indeed goes into the branch we hope for.
Using H5_HAVE_INSTRUMENT macro to isolate these changes so that it won't affect or be misused by the application.
Platforms tested:
h5committest(shanti still refused to be connected)
Parallel tests on heping somehow are skipped. Manually testing at heping. Have checked
1,2,3,4,5 processes.

Add tests for optional APIs to support collective chunk IO
Description:
In order to test whether library picks up the user's options,
The number of chunks need to be varied for different processes,
Selection of the number of processes selected in one chunk also
need to be varied.
Solution:
Create two cases,
1. Each chunk only selected by one unique process, this case
library should use independent for collective call.
2. One-third of the processes occupies the top half of the whole domain,
The rest of the processes occupies the lower half of the domain.
The total number of chunk is a fixed number 8.
Platforms tested:
Linux 2.4 with mpich 1.2.6(only)
Since I only checked in the code that handles the selection, haven't added any new tests yet. So it won't affect any platforms.

change the array size of collective chunking features of parallel tests.
Description:
Previously array size for collective optimization tests
including
cchunk1,
cchunk2,
cchunk3,
cchunk4,
ccontw,
ccontr,
cschunkw,
cschunkr,
ccchunkw,
ccchunkr
are fixed,
They are only valid for some good number of processors(1,2,3,4,6,8,12,16,24,32,48 etc).
Recently there are more requests for parallel tests to be valid on some odd number of processes such as 5,7,11,13 etc.
Solution:
I change the array size to be dynamic rather than static. Now the fastest change array size is a function of mpi_size. dim2 = constant *mpi_size. After some tunings, theoretically the above tests should be valid for any number of processors. However, other parallel tests still need to be tuned.
To verify the correctness of these tests, using mpirun -np 5 ./testphdf5 -b cchunk1 at heping.
Platforms tested:
h5committest(shanti is refused to be connected)
at heping, 5 and 7 processes are used to verify the correctness.

Add new tests
Description:
Collective IO doesn't work for some platforms/mpio packages when more than
one process has no contributions to IO.
Solution:
1. Add a collective IO test to verify the correctness of the library when
more than one process has no contributions to IO.
2. Add the similar MPI-IO test in t_mpi to help us maintain in more platforms.

bug fix 504
Description:
testpar/t_mpi would hang if $HDF5_NOCLEANUP is set. E.g.,
% env HDF5_NOCLEANUP=yes mpirun -np 3 ./t_mpi
This happened because the environment variables are not exported to all
mpi processes by the mpirun command. So, some attempted to do cleanup
while others don't and some hang waiting for others to act.
Solution:
Instead individual program checking getenv, they all just called h5_cleanup
no matter. h5_cleanup now uses getenv_all to check the $HDF5_NOCLEANUP if
it is in parallel mode.
Platforms tested:
h5committested, tested pp in heping too.

Patch.
Description:
Copper would fail with a message of
0032-113 Out of memory in routine unknown, task 0
when run with 3 processes and size 1MB in MPI-IO tests.
It seems to be a copper MPIO error.
Solution:
Reduced the upper bound of default write size to 1/2MB (but
tests only go to 1/4MB) for now, pending permenant fix from
Copper.
Platforms tested:

Minor bug fixes.
Description:
1. Changed free() calls to HDfree()
2. Corrected behavior of -m command-line parameter
3. Changed return value to always return 0.
Solution:
2. The -m flag tells the test to run only the MPI IO tests. However, it would incorrectly make
the test run both the MPI and POSIX tests (same as the default behavior).
3. This test is known to fail on many platforms, and, even on those platforms where it usually passes,
it is known to suffer transient failures (especially with small test file sizes). It's outcome is
also very dependent on the filesystem on which the testfile is created. Corrected
the program to always return success, so that it doesn't interfere with the daily tests.
The motivation for this is that
this test has nothing to do with the HDF library and is an auxiliary test. Failures in t_posix_complaint
do not necessarily mean that parallel HDF will fail, but simply indicate something to look into,
especially on new platforms. This is now an "output only" test, and any errors will be only be visible
in the output.

copper (all of these were minor changes)

bug fix.
Description:
Fixed the segmentation fault errors in modi4, copper and tg-login.
It was due to the misuse of trying to realloc a pointer returned by
getenv_all. (not supposed to.)
Also rearranged the code so that option is checked first, then check
with environment variable, then use default setup. This saves the
need to do realloc at all.
Platforms tested:
Heping, modi4, shanti, copper (copper showed a different error now.)

parameter is passed to the program to specify a path, it will override the value of
HDF5_PARAPREFIX.

Description:

Solution:
These tests do increasingly complicated sets of writes followed by reads.
POSIX standards say that any read that can be proven to occur after a write
must include the data in that write. These tests attempt to verify whether the
underlying filesystem and i/o layer provide such guarantees.

Bug fix
Description:
Before this checkin, 'gmake check-s' would fail if there was a file in
the current directory named 'check-s'.
This is fixed under gmake (not sure how to fix for other makes).
Solution:
check, progs, install, etc. are what gmake calls "phony" targets,
which means that no file should be created. These targets can be
specified by a line of the form
.PHONY: check progs install ...
Automake adds this line for targets it knows about, but HDF5 has a
lot of custom rules. This checkin adds a .PHONY line for those rules.
I believe that only gmake recognizes the .PHONY line (at least, pmake
doesn't seem to), but a partial solution is better than none.
This error should occur very rarely anyway (the user has to manually
create files with names like 'build-check-s' or '_test').

Bug fix/feature
Description:
Added support for -shlib in h5fc and h5c++.
Made check-install use -shlib when only shared libraries have been installed.
Solution:
h5fc and h5c++ didn't recognize -shlib. Stole code from h5cc to link against
shared libraries.
When static libraries are disabled, the examples Makefiles will automatically
use the -shlib option to link against shared libraries. Thus,
--disable-static and make check-install should work together.

Bug fix
Description:
Changed configure.in to use an environment variable TR to set the path
to the tr utility.
Solution:
There are two kind of tr on Solaris with slightly different syntax.
HDF5's configure relies on the "standard" tr. Traditionally, HDF5ers
have needed to make sure that the "right" tr was found before the
wrong one in their path; now they can use an environment variable.

Makefile bug fix
Description:
Previously, automake didn't output rules to build perform/mpi-perf or
the test/gen_* programs.
Now these can be built by typing 'make mpi-perf' (or 'make foo') or by
configuring with --enable-build-all.
Solution:
Automake doesn't like having rules for programs it doesn't build. Tricked
it by having these programs built "sometimes"--whenever the user enables
--build-all. This should be used mostly for testing and to ensure that
these helper programs compile.
***IMPORTANT***
These programs do *not* currently compile. When --enable-build-all is used
(not the default), gen_new_fill fails because it uses an old API. This is
an existing "bug" that has simply been exposed by this checkin.
Platforms tested:
sleipnir, modi4, sol

bug fix.
Description:
The complex derived datatype test assumed that the fill value would be 0. This is not
the case on all systems.
Solution:
Modified the test to check against a known value in the outbuf array, instead of the fill value.
Platforms tested:
heping and MCR.

Description:
Fixed typo in a comment. The word "file" was supposed to be "fill." The explanation of
how the complex derived datatype test works is much clearer now.
Solution:

bug fix.
Description:
When a parallel test script test fails, make would continue because the
way it was setup inside a for loop. Fixed it by issuing an exit 1 inside
the loop.
There was also a typo error in the newer command comparision that it
must be $${chkname} in order to be valid. Also, the test script itself
was not checked in the newer lists. All fixed.
Platforms tested:
h5committested and also hand tested in heping pp mode.

Repair synchronization bug in the metadata cache in PHDF5
Also repair numerous other bugs that surfaced in testing the
bug fix.
Description:
While operations modifying metadata must be collective, we allow
independant reads. This allows metadata caches on different processes
to adjust to different sizes, and to place the entries on their dirty
lists in different orders. Since only process 0 actually writes
metadata to disk (all other processes thought they did, but the writes
were discarded on the theory that they had to be collective), this made
it possible for another process to modify metadata, flush it, and then
read it back in in its original form (pre-modification) form. The
possibilities for file corruption should be obvious.
Solution:
Make the policy that only process 0 can write to file explicit, and
visible to the metadata caches. Thus only process 0 may flush dirty
entries -- all other caches must retain dirty entries until they are
informed by process 0 that the entries are clean.
Synchronization is handled by counting the bytes of dirty cache entries
created, and then synching up between the caches whenever the sum
exceeds an (eventually user specified) limit. Dirty metadata creation
is consistent across all processes because all operations modifying
metadata must be collective.
This change uncovered may bugs which are repaired in this checkin.
It also required modification of H5HL and H5O to allocate file space
on insertion rather than on flush from cache.
Platforms tested:
H5committest, heping(parallel & serial)

A bug fix
Description:
MPI_Status_IGNORE is treated as a NULL pointer for mpich 1.2.4 or similar MPI packages.
It caused segmentation fault for MPI derived datatype test.
Solution:
Define MPI_STATUS status,
and pass &status into MPI_File_read and MPI_File_write.
Platforms tested:
too trivial to test.

Improvement.
Description:
The test may hang if there are system failures that some processors
are not working.
Solution:
Added the ALARM calls to limit all tests be done with the default
alarm time. So, even if a process is hanging, the ALARM signal
would terminate the process.
Platforms tested:
tg-login2 of NCSA.
