Bug fix
Description:
ph5diff had been hanging in Tflops. Found out that vsnprintf ph5diff
uses was a local coded that did not limit printing according to the size
argument. That resulted in buffer overflow and other problems.
Solution:
Added some sort of size checking in the home-grown vsnprintf and
had ph5diff checked for error return of vsnprintf. Leon also
revamped the ph5diff manager's way of handling communications with
the workers. That eliminated all but the last case of hanging.
Platforms tested:
Tflops.
Misc. update:
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

Too minor to require h5committest
Bug fix for parallel case for new "Some objects were not comparable" patch to h5diff.
Description:
The parallel h5diff wouldn't print out "Some objects were not comparable" because the worker
tasks were not communicating the not_cmp flag of the diff_opt_t struct back to the manager, who ultimately
prints everything.
Also, some miscellaneous fixes for error printing. Some errors were printed out with printf instead of fprintf(stderr,...).
In parallel environments, this can result in output getting lost.
Solution:
Had the worker tasks pass along the not_cmp flag to the manager when they sent along
the number of differences they found.
Platforms tested:
heping (pp), sol (pp)
Misc. update:
bug fix
Description:
when 2 objects were not comparable, the final print information for the non verbose mode printed "0 differences found"
Solution:
replaced instead with a Summary message that says
"Some objects were not comparable"

Bug Fixes
Description:
Fixes for several bugs, including dumping of excess output to a temporary file, fix for printing
hsize_t datatype, and the long awaited fix for intermixed output.
Solution:
Fix 1: Overflow file
Previously, any output that a worker task made was buffered locally in memory, up to a point. Any
output beyond the size of the buffer (used to be 10k) was discarded. Now, the memory buffer size has been
changed to 1k and any output beyond this amount is sent a temporary file. This way, no output is lost
and memory usage is kept under control. The temporary file is deleted as soon as a worker task finishes
sending its contents to the manager.
Fix 2: hsize_t printing
Printing of the hsize_t datatype used to be handled by %Hu passed to HDfprintf. However, there is no corresponding HDvsnprintf that
is able to print hsize_t types. These are now printed with the aid of H5_PRINTF_LL_WIDTH.
Fix 3: Intermixed output fix
Intermixed output would occur on some machines (although I haven't seen it happen for a while) due to the unpredictability of the underlying network
and the speed at which various message would travel. This has been fixed by having all output send to the manager
for printing. The worker tasks no longer print the output themselves upon receipt of a token, but instead
send that data to the manager.
Platforms tested:
heping, eirene, tg-login (the only place that seems to still experience intermixed output every now and then)
Misc. update:
Bug fix.
Description:
MPI_LONG_LONG, which is not standard yet, was used to pass the
nubmer of differences found. This was needed because number of
differences is defined as type hsize_t which can be arbitary large
such that there is no MPI type that matches it. The value is passed
between processes as an array of bytes in order to be portable. But this
may not work in non-homogeneous MPI environments.
This fix was actually Leon's idea.
Platforms tested:
Tested in QSC in which this failed.
Correction to previous print_manager_output bugfix
Description:
Although the previous bugfix did fix all the errors, it was not the correct way
to fix the problem. Since the manager will only buffer output when run in
parallel mode, in serial mode this function should not even be called.
Solution:
Wrapped print_manager_output in #define's to prevent it from being included in
serial builds.
Platforms tested:
heping (serial + parallel)
Misc. update:
Bug fix.
Description:
print_manager_output was missing because it was compiled in
only parallel mode.
Solution:
Made it available all the times.
Platforms tested:
h5committested. (testph5diff.sh failed in copper but that
is a different error.)
Also tested in heping, serial and pp.
Misc. update:
Fixed numerous ph5diff bugs.
Description:
Fixed manager output printing
Fixed out of order output printing
Fixed test script execution problem
Temporary fix for large amounts of output overflowing buffer.
Solution:
The manager task buffers its output. However, since the manager task
never gets a print token, this output was lost. Solution: new function called
print_manager_output that prints buffered output is called in places where the
manager buffers its output.
printf was apparently buffering output. This means that a task would sometimes
print even after it had given up its print token. Added fflush() call after
printf() calls, which seems to have fixed the problem.
calling rsh multiple times in succession seems to overwhelm something in Linux,
as it begins to refuse new connections until the old ones reset. Since each
call to mpirun in the test script starts up 4 rsh sessions, the test script
eventually is unable to run any further tests. Solution: Added a short delay in the
testscript between successive calls to mpirun to allow old connections to reset.
The 10k output buffer was of insufficient size to hold the large amounts of
output generated by some of the tests. Since code to buffer to a file has not
been implemented yet, a temporary fix was to increase the size of the output
buffer to 50k.

Bug Fix
Description:
Permanent fix for the incompatibilities between h5diff and h5repack.
Solution:
h5diff now contains the code to run both parallel and serial diffs.
Depending on how the binary is called, it will run either the serial or
the parallel versions respectively.
Platforms tested:
heping(serial + parallel), copper.
Misc. update:
Bug fix: Temporary fix for h5repack failures in all parallel builds.
Description:
The parallel additions to h5diff interfered with h5repack.
Solution:
Added a second set of "parallel" functions to h5diff.c. h5repack uses the serial versions, whereas h5diff will use the parallel versions.
Also, h5diff will now be smart about when to enter parallel mode. If is run with mpirun with more than 1 task, it will enter parallel mode. Otherwise, it will stay in serial mode as before.
Platforms tested:
heping (serial and parallel)
Misc. update:
New feature.
Description:
Added new tool ph5diff. (Code done by Leon Arber.)

it skipped all tests.

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".

Report mode: print the above plus the differences
Verbose mode: print the above plus a list of objects and warnings
Quiet mode: do not print output (h5diff always returns an exit code of 1 when differences are found)
h5repack
added an extra parameter for SZIP filter (coding method)
the new syntax is
-f SZIP=<pixels per block,coding>
(pixels per block is a even number in 2-32 and coding method is 'EC' or 'NN')

./h5repack -i file1 -o file2 -f SZIP=8,NN -v
