New feature
Description:
Add new "block tracker" data structure to library, for tracking blocks of
bytes in a file. Block trackers will be used to keep track of the blocks
belonging to the soon-to-be-implemented "segmented heap" which is designed to
replace the current local & global heaps (starting with the local heap).
Block trackers will also keep track of the free space in the segmented heap
and someday could be used to track the free space in the entire HDF5 file.
They are implemented as a small header of information to cache the state
of the blocks (max & min sizes of blocks tracked, etc.) and the records of
the blocks themselves are stored in a v2 B-tree.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)

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:
Automake version upgrade
Description:
Upgraded automake version from 1.6.2 to 1.9.5.
Changed bin/reconfigure script to use automake 1.9.5.
Changed configure.in and Makefiles to use new FCFLAGS and FC variables
instead of FFLAGS and F9X.
Automake and configure should now do the lion's share of the work
supporting Fortran 9X; macros in acsite.m4 are now mostly unused (will
be cleaned later).
Altered how configure handles pmake; now root-level Makefile.in is
processed by bin/reconfigure to have a .MAKEFLAGS target, since
automake no longer allows us to define unused variables.
Configure now always checks for C++ compiler even if it is not
used, since automake thinks this is the Right Thing To Do and
will break otherwise.
Platforms tested:
Sol, copper, heping, mir, sleipnir, eirene, pommier, kelgia, modi4.
Bug fix
Description:
The GASS VFL driver header file was bringing in the <string.h> header file,
which several other source code modules needed also, but weren't including
explicitly themselves.
Solution:
Add includes for <string.h> to files which actually need them.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/C++ as CC
Configuration not tested by h5committest...
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.
Removed GASS configuration and software packages associated with
it. The following software are no longer configurable.

Description:
h5repack support for scaleoffset compression
Checking in early to help debug the filter.
Solution:
Added messages and command line to handle new scale offset filter.
Note: TESTS ARE DISABLED FOR NOW. The filter is not
complete, repack tests may fail due to know problems.
PLEASE DO NOT MESS WITH THE SCALEOFFSET TESTS AT THIS TIME.
They will be enabled when the filter is ready.

Misc. update:
MANIFEST
Description: On SGI Altix(cobalt) Linux, wrong values were printed out for enum data type
members. No apparent reason was discovered.
Solution: use another pointer to the buffer containing the member value. It seems fix the
problem.
Platforms tested: cobalt - simple change, where the bug was discovered.
bug fix.
Description:
When MPE library is used, it prints two extra message lines that
interfere with the expected output.
Solution:
Filter out those two lines of text from stderr.
Also added a provision to print the whole generated output when failure
is detected.
Platforms tested:
Tested in copper, serial, parallel and parallel with MPE.
Misc. update:
bug fix/new feature.
Description:
(committing changes made by Leon.)
ph5diff now is a real program by itself. It has its
own main (ph5diff_main.c).
Codes common to h5diff and ph5diff are in h5diff_common.c.
Removed the hack that hide failures from testh5diff.sh.
Platforms tested:
heping(serial, pp), sol (pp), copper(pp).
Misc. update:
Purpose:
Bug fix
Description:
modi4 dies during build with strange errors.
The root cause of these is a two-year-old hack in HDF5's libtool
script that only takes effect on IRIX.
Solution:
Edited the libtool hack (by editing ltmain.sh) to correct a bug in
the hack.
Also made sure that compiler-specific DEFAULT_LIBS are used
when linking.
Platforms tested:
sleipnir, copper, modi4, sol
Bug fix.
Description:
ph5diff is still being fixed.
Changed this to report all failures but will not flag them as
errors so that daily tests can continue. Will be fixed soon.
Platforms tested:
Tested in sol (pp) where it has most failures.
Misc. update:
bug fix
Description:

Solution:
Platforms tested:
linux (small change)
Misc. update:
Purpose:
Bug fix
Description:
Fixed the error on copper where output would match, except the worker tasks are forcefuly terminated at the end.
Solution:
If an exit code other than 0 was returned, the
parallel environment would assume that there
was an error and would terminate all other
tasks. Because h5repack relies on the return
value of h5diff, it was necessary to return
values other than 0. Fixed by having parallel
runs of h5diff always return 0, whereas the
return value of serial runs is unchanged.
Platforms tested:
copper
Misc. update:
Bug fix
Description:
Arabica exhibited strange errors when linker found wrong versions of
header files. This happened because include directories were
given to linker in the wrong order.
Solution:
Move include directories from AM_CFLAGS variable to INCLUDES
variable to put them before CPPFLAGS variable. Trust me, it works.
This bug may also have contributed to strange errors on other platforms
(kelgia?).
Platforms tested:
copper, sleipnir, arabica.
(h5dump broke while building on arabica, but this happened in
a clean checkout, too).
Bug fix
Description:
pmake (on modi4, for instance) complains about undefined variables
if it is run without the -V flag, which turns those errors to warnings.
Solution:
Added test to configure.in to see if $MAKE will allow Makefiles
with undefined variables. If not, sets -V flag in AM_MAKEFLAGS.
Ensured that all custom make targets use AM_MAKEFLAGS.
Also defined all variables that caused errors in top-level Makefile.am.
This means that pmake can be used to build hdf5 *from the top level
only*. To run make from a subdirectory, still need to use -V flag
(or use make or gmake).
Platforms tested:
modi4, heping, copper, sleipnir
bug fix.
Description:
Need eval before the RUNCMD command because some machines like
AIX, has RUNPARALLEL in the style as
MP_PROCS=3 MP_TASKS_PER_NODE=3 poe ./a.out
that throws the shell script off.
Platforms tested:
Tested in copper (pp) where it failed before.
Tested in heping pp too.
Misc. update:
Bug fixed.
Description:
Heping used to have a network limit that if too many rsh connections
occurred in a second, it stopped accepting connections for 30 seconds.
That caused testph5diff to fail when too many mpi jobs are executed
repidly. A sleep 2 was in to go around this problem. Heping's limit
has been raised, thus no more need for this hack. Sleep 2 is removed.
Platforms tested:
Tested in heping (pp).
Misc. update:
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:
Purpose:
bug fix
Description:

this was causing compiler warnings with g++
Solution:

Description:
g++ was not happy with missing protocols of external functions.
Added print_manager_output(void) and phdiff_dismiss_workers(void)
to the public declarations.
Platforms tested:
Tested in sleipnir (g++) and heping (serial, pp)
Misc. update:
Purpose:
bug fix, new test file
Description:
h5dump was not properly displaying array indices > 3D
Solution:
added the same algorythm and data structure that h5diff uses to calculate the array index
from a element number position
Platforms tested:

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.
Platforms tested:
heping
Misc. update:
Description: The byte order for all 1-byte integer types was fixed as little-endian
even on a big-endian machine. This's corrected in h5detect.c. When types are only
1 byte long, a native int is used substitute the type to detect byte order. Some tools
like h5dump and h5repack are also corrected in this case.
Platforms tested: fuss, copper, sol.(There're some failures from the recent configure
change).
Misc. update: Information in the RELEASE.txt.
Bug fix
Description:
h5diff sometimes will 'exit(status)' but if it is in parallel mode,
it needs to close up the workers and the MPI environment before exit(..).
Solution:
Created h5diff_exit() that will just exit in serial mode but does all
the shutdown properly if in parallel mode.
Platforms tested:
tested in heping, serial and parallel.
Misc. update:
Feature
Description:
Added a new function, phdiff_dismiss_workers, which tells the phdiff
worker processes to end.
Platforms tested:
Tested in heping, serial and parallel.
Misc. update:
Bug fix
Description:
h5diff_main.c contained some debug printf statment that produced
unexpected output. Commented them out.
testh5diff.sh: implemented code to test ph5diff tests but
ph5diff has some errors that generated unexpected output.
Temporary hacked to skip tests if run by daily test account.
Platforms tested:
Tested in heping, serial and parallel.
new features
Description:
Added a parallel option to testh5diff.sh to do parallel h5diff tests.
Added testph5diff.sh to invoke testh5diff.sh with parallel mode.

Purpose:
Bug fix
Description:
Parallel builds were breaking in tools/lib
Solution:
talign didn't realize it depended on libh5tools.la because its
dependencies listed the full path (../../tools/lib/libh5tools.la).
Changed this, and made similar changes in a couple of other
directories.
This checkin should also add the --foreign flag to every Makefile.in
Platforms tested:
sleipnir (minor change)

Too minor to require h5committest
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
Description:
Found the permanant fix to automake/CVS dependency problem
Solution:
Added AM_MAINTAINER_MODE macro to configure.in.
Now automake will never try to regenerate Makefiles, Makefiles.in,
configure, H5config.h, etc. when they are out of date, nor will it
print any warnings.
Developers should be very very careful to use reconfigure script,
and can add --enable-maintainer-mode flag to configure on heping
to regenerate these files correctly.
