bug fix
Description:
I introduced some #ifdef <have_filter> on the check in yesterday on the places
that generated datasets, that had no corresponding on the read part.
this caused failures in the configurations where a filter was not defined
Solution:
just removed the #ifdefs
Platforms tested:
linux
Misc. update:
bug fix
Description:
generating a dataset in linux 2.4 (verbena) with the pgcc compiler gave an error with the following
sequence
1) make a space id1 and a dcpl
2) make a space id2, create and write a dataset with space id2, close
3) attempt to create a dataset with space id1 fails and calling a set_filter function with the dcpl in 1) fails
Solution:
just changed the order 2) to 1)
Platforms tested:
linux 2.4 (verbena) with pgcc compiler
Misc. update:
Purpose:
Clean up RM formatting.
Modify RM HTML code to facilitate automated generation of PDF version.
Minor edits.
Description:
Reworked format of "Parameters" sections.
Added HTML tags (and pseudo-HTML tags) used by HTMLdoc to
generate PDF files.
Fixed the "Copyright" link on RM_H5Front.html.
Other minor copy edits.

bug fix in H5Zshuffle.c
add more tests to h5repack that exposed the bug
Description:
when creating a dataset with the shuffle filter and duplicating it in a new dataset (file)
the call to H5Z_set_local_shuffle failed. this is because the value of cd_nelmts of the filter
structure is set to 1 (H5Z_SHUFFLE_TOTAL_NPARMS) when the original dataset is created, but when
the new dataset is created there is a checking instruction that fails if the value of
cd_nelmts is not 0 (its original value, H5Z_SHUFFLE_USER_NPARMS)
Solution:
just remove that check condition, since the value of cd_nelmts is not used anyway.
if we decide that the value of cd_nelmts is necessary, then the H5O_pline_copy function
must be changed to update this value (a different update for each filter)

Bug fix.
Description:
The -g in H5detect somehow does not work with 64bit mpicc in arabica.
Remove it for now for better solution.
Platforms tested:
no test as the change is trivia.
Misc. update:
Bug fix, sort of.
Description:
Some compilers, e.g., intel compiler, would take a long time
to compiler H5detect.c if optimization is on.
Solution:
Setup special make rules for H5detect to be compiled always with
optimization off by using -g. Since H5detect is run once to generate H5Tinit.c,
it does not matter that much if it is optimized or not.
Platforms tested:
"h5committested".
Tested in Titan too.
Code cleanup/bug fix
Description:
Fix configuration files to allow 64-bit compilation of the library with
a 64-bit version of zlib.
Solution:
Moved important compiler flags settings from CC macro to CFLAGS macro.
Instead of setting CC (F9X, CXX) environment variable for compiling for 64-bit
code, users should just set the CFLAGS (FFLAGS, CXXFLAGS) to -q64.
Updated INSTALL file to reflect this change.
Platforms tested:
IBM p690 (copper) w/parallel, FORTRAN, C++, srcdir.
Platforms specific - h5committest does not apply.
small bug fix
Description:
a dataset creation property list was not closed
Solution:
closed it, calling H5Pclose(dcpl);

Bug fix
Description:
Added directory where actual source code is located to allow broken Intel
C 7.1 compiler to generate dependencies correctly.
Platforms tested:

removed some harcoded zlib and szip library paths from the h5repack project
settings that were accidently left there

Description:
"make check" failed because the macro "$<" is not known to those
makes.
Solution:
Replace that macro with a string name in the form of a more basic
macro of "$@".
Platforms tested:
h5committested (copper used make.)
Misc. update:
new feature, bug fix, changed function
Description:
1) implemented the option that says if the dataset is too small , do not compress it
2) bug fix in the SZIP checking . only apply szip to atomic datatypes
3) made the apply_filters function more compact

compiler which seems to have bugs in its -MG flag for creating dependency
information.

too obscure to require testing on other platforms
Bug fix
Description:
make check without doing make first would fail to build testphdf5.
Solution:
Put the testphdf5 back in the target of TEST_PROG_PP and removed
the "testphdf" without any parameter from testph5.sh.
Platforms tested:
copper parallel. This is not relevant to non-parallel cases.
Misc. update:
Description: Temporarily disable float(or double) - unsigned long long
software conversion because there is a bug in pgcc compiler. Will enable it
once the problem is solved.

Code cleanup/optimization
Description:
Query property list values once, at the beginning of the I/O routines,
instead of querying the property list values multiple (lots!) of times in

list values.

linux
Misc. update:
Bug fix.
Description:
Revert the optimization to the MPI-I/O VFD from earlier this week that
eliminated calling MPI_File_set_size() when a file was truncated. This doesn't
work because of the way we track the 'eoa' (end of allocated space) in the
file: we just advance the eoa value when space is allocated in the file and we
don't zero out the space in the file. This causes a problem where we assume
that all "newly allocated" space in the file contains zero bytes, but if we
don't call MPI_File_set_size(), the file can contain the previous data (if the
file previously existed) and not zeros.
Unfortunately, because we allow independent raw data parallel I/O, there
is no way to address this issue. :-(
Solution:
Revert to previous method of retrieving the file's size, etc. from before
the optimization.
