Add a file that I forgot in my last checkin.
Description:
t_cache.c is the source file for the new parallel metadata cache test.
Solution:
See above.
Platforms tested:
h5committested before the last checkin. Will run another
h5committest shortly, but it shouldn't be necessary as there
are no new changes.
Misc. update:
Add files that I forgot in my last checkin.
Description:
cache_api.c cache_common.c cache_common.h are new files that result
from breaking the old cache test into two tests.
Solution:
See above.
Platforms tested:
h5committested before the last checkin. Will run another
h5committest shortly, but it shouldn't be necessary as there
are no new changes.
Misc. update:
Bug fix/additional tests
Description:
Add additional tests for holding open an object of a given type (dataset,
group, etc) while incorrectly trying to open that object with a different
type of API routine (i.e. using the group open call on a dataset, etc.)
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Bug fix & new feature
Description:
Support variable-length datatypes in compact data storage and chunked
data storage, along with attributes.
Bug fix on the H5T_vlen_set_loc to allow for changing the file on a
variable-length datatype on disk.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4
Can't h5committest right now, due to missing cache files.
1) Add parallel test for metadata cache
2) Split serial test for metadata cache into two parts
3) Fix bug in which cache was flushed needlessly when the
cache wasn't full.
4) Performance improvements
5) Update API for parallel cache coherency bug fix.

Platforms tested:
h5committest
Misc. update:
Bug fix.
Description:
Seems like some compilers don't like the "inline" function spec.
Solution:
Removed the inline description for the sub_time function.
Platforms tested:
heping and tg-login.
Misc. update:
Feature, address bug #426
Description:
The h5perf test now also keeps track of the time it takes to:
open a file: Time between start of open and start first read/write
close a file: Time between end of last read/write and end of close.
This information is only displayed if debug output printing is enabled (level 3 or higher)
Solution:
The test actually has all of the data necessary to compute the time it takes to open
and close a file; it just wasn't recording it. Added 4 new timers:
HDF5_FILE_READ_OPEN
HDF5_FILE_READ_CLOSE
HDF5_FILE_WRITE_OPEN
HDF5_FILE_WRITE_CLOSE
that keep track of the time to open/close a file opened for reading/writing.
Platforms tested:
heping and mir
Misc. update:
Description: h5_group example didn't work on VMS; it turned out
that a group was not closed and since the default
file close degree is "weak", file was not closed either.
When program attempted to open the same file, system reported
an error since the file was "locked by another user".
UNIX systems apperently do not care and open the same file
without any problem.
Solution: Added H5Gclose calls.
Platforms tested: VMS server and heping
Misc. update:
Code cleanup
Description:
Check in some of the code cleanups from working on the external link
support. (This doesn't include any of the external link features)
Platforms tested:
FreeBSD 4.11 (sleipnir)
Mac OSX.4 (amazon)
Linux 2.4
Description:
Removed the call to h5_test from dsets.cpp, since resetting
the library made the C++ global constants become invalid.
Platforms tested:
Linux 2.4 (heping)
SunOS 5.8 64-bit (sol)
Description: Revise a few details of H5LTtext_to_dtype() and H5LTdtype_to_text(),
1. changed the DDL definition of string, opaque, and compound types.
2. added a new parameter of H5LT_lang_t type to these two functions.
Platforms tested: h5committest and fuss.
bug fix
a call to sprintf was giving incorrect output in the system Fedora Core 4 with gcc 4.0
(not supported by us, but user reported)
Solution:
the call was using the same buffer for source and destination variables, used different ones
Platforms tested:
linux (mir)
solaris (sol)
Misc. update:
Bug fix.
Description:
Fixed a typo and also moved initialization of n_xxxx variables to the
common declaration place.
Platforms tested:
Tested in v1.6 branch already.
Bug fix.
Description:
getenv_all, like some implementations of getenv, keeps an internal buffer
for the getenv values. Application must make a copy of the content of the
returned pointer before calling getenv_all again IF it wants to use the
first content later. The previous code violated this rule and caused
error.
Solution:
Did a small revamp of the h5_fixname to fix the above problem by moving
the getenv_all for HDF5_NOCLEANUP eariler to avoid it clashing the
call of getenv_all for HDF5_PARAPREFIX. No a good permenant fix. Need
to really recode this routine.
Platforms tested:
h5committested.
Copyright fix
Description:
The packet table examples were breaking the copyright checking script.
Fixed them.
Also caught a one-line copyright problem in another file.
Platforms tested:
Only changed comments.
Bug fix.
Description:
getenv_all will be called even when it is NOT an MPI application.
Solution:
Moved the use of getenv_all("HDF5_NOCLEANUP") to fix_name so that it will
be invoked only if a parallel driver is used.
Platforms tested:
hand tested in copper.
Makefile fix
Description:
perform/h5perf is (currently) a test for parallel performance, but was
being built when parallel was disabled. Fixed this.
perform/perf had the same problem.
Solution:
Actually, perf and h5perf were being "built but not executed"
using two different mechansims. They now use the same mechanism,
being built and executed in parallel only.
Platforms tested:
mir, heping, sleipnir
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.
Cleaned up reconfigure output
Description:
Added two lines to separate output from trace script from autotools
output in reconfigure.
Solution:
Running reconfigure updated src/Makefile.in as a side effect, since
I changed config/lt_vers.am in my last checkin but forgot to
run reconfigure then.
Platforms tested:
mir (cosmetic change to reconfigure script only)
Bug fix.
Description:
release created temporary files in .. directory. If the -d directory
is the same as the parent directory, it would fail when it tried to
copy the temporary files to the destination directory.
Solution:
Changed release to create a temporary directory and create all temporary
files in that temporary directory.
Platforms tested:
Handtested in heping.
Code cleanup/update
Description:
Update compiler flags for gcc 4.1.x & start cleaning up some of the C++
compatibility
Platforms tested:
FreeBSD 4.11 (sleipnir) w/gcc 4.1 and/or g++
Feature
Description:
Added character encoding and attribute creation property lists.
Solution:
Attributes' character encoding is set via the ACPL.
The default is ASCII, with UTF-8 being the other option currently.
Platforms tested:
heping, mir, sleipnir, copper
Description:
Added missing member function H5File::flush
Fixed parameters passed to H5Awrite
Other typos
Platforms tested:
Linux 2.4 (heping)
SunOS 5.8 64-bit (sol)
Maintenance on Windows
Description:
Update project file because the source file names have benn changed
Solution:
Platforms tested:
WIndows XP
Misc. update:
Bug fix
Description:
Retrieving an object's name could fail (in various ways) under certain
circumstances (mostly having to do with mounted files).
Solution:
Re-write & simplify "get object name" code to fix error in a better way
than adding yet another hack to the previous pile of hacks... :-)
Platforms tested:
FreeBSD 4.11 (sleipnir)
