Code checkpoint
Description:
Checkpoint fractal heap improvements, as well as move the free space
manager code that it's using into a separate package.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4/64 (mir) w/C++ & FORTRAN
Linux 2.4/32 (heping)
Solaris 2.9 (shanti)
AIX 5.? (copper) w/FORTRAN & parallel
Description: Function prototype H5E_walk_t and structure H5E_error_t wasn't backward
compatible.
Solution: Make them compatible with v1.6 and provide new definitions of H5E_walk_stack_t
and H5E_error_stack_t.
Platforms tested: fuss and h5committest.
Purpose: Maintenance
Description: dtypes.c compilation failed with gcc 4.1 due to the
missing prototype of the opaque_funcs function.
Failure was reported by a user who tried to build
hdf5-1.8.0-alpha2.
I reproduced the failure on sleipnir with gcc41
compiler.
Solution: Added prototype definition.
Platforms tested: sleipnir with gcc41, heping and copper
Misc. update:
Bug fix
Description:
A datatype wasn't being closed in th5s.c
Solution:
This minor oversight caused an error with my Object Header code.
The datatype is now closed in the test.
Platforms tested:
windows, mir, copper
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.
Misc. update:
Code checkpoint
Description:
More progress on fractal heap, can now re-open an existing heap, although
the free space algorithm still needs work.
Also, use the new "pinned entry" metadata cache code.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (heping)
Solaris 9 (shanti)
Linux 2.4/64 (mir)
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...
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Linux 2.4/64 (mir) w/C++ & FORTRAN
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:
h5committested -- minus one small typo in test/cache.c whose fix was
tested on copper and heping only.
Misc. update:
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)
Description:
The file size test in C++ library failed on Copper because the
value returned by h5_get_file_size was intepreted incorrectly
due to different interger sizes.
Solution:
H5private.h: Added check to use stat64 and off64_t where appropriate.
h5test.c and h5test.h: used h5_stat_size_t in place of off_t.
tattr.cpp: used h5_stat_size_t in place of off_t.
Platforms tested:
Linux 2.4 (heping)
AIX 5.1 (copper)
SunOS 5.8 64-bit (sol) - still on going
Bug fix.
Description:
It did not handle the case when version sub-release string is not
empty.
Solution:
Fixed the sed substitution to remove the sub-release string too.
Platforms tested:
Heping.

Code checkpoint
Description:
Add in more fractal heap support for odd allocation patterns (entries that
are too large for various block sizes, etc.)
Broke out fractal heap code into more source code modules.
Refactored fractal heap test to make it more understandable and
maintainable for the long term.
Platforms tested:

Linux 2.4/64 (mir)
Solaris 2.9 (shanti)
Anti-feature
Description:
Revert changes to H5G_stat_t struct, to make it compatible with the 1.6.x
branch again. The information that was added to the H5G_stat_t struct will
be reported through other API routines.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/C++
Linux 2.4/64 (mir) w/C++ & Fortran
Solaris 2.9 (shanti)
new feature
Description:
1) separated the HL library into "public" and "private" header files, with the same caracteristics as the basic library
2) added the public headers to hdf5.h (with a conditional include macro, defined in configure.in)
3) added the path to HL in all Makefile.am 's , because of the inclusion in hdf5.h
Solution:
Platforms tested:
linux 32, 64
AIX
solaris
with fortran and c++
(one packet table example fails)
Misc. update:
"Hide" file format changes (for now)
Description:
Add ifdef's (controlled by the --enable-group-revision configure flag)
to disable group revision changes to the file format, in order to allow alpha
release to go ahead without releasing an unsupported version into the wild.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 32-bit (heping)
Linux 2.4 64-bit (mir)
Solaris 2.9 (shanti)
feature
Description:
Added the GetTestExpress and SetTestExpress to support the TestExpress mode
according to $HDF5TextExpress. For now, it is just defined or not, the
actual value does not matter.
Platforms tested:
heping(serial), mir (PP).
Bug fix.
Description:
getenv_all would fail if one calls it without calling MPI_initialized first.
This may happen if one uses PHDF5 library to build a serial nature code
and does not make any MPI calls.
Solution:
Added code to detect if MPI has been initialized. If not, use the
original getenv.
Platforms tested:
heping (serial) and mir (parallel).
Bug fix
Description:
Correct the handling of the group creation property list when copying
objects with the "create intermediate groups" flag.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest (once I pay attention to the compiler
warnings... :-)

Description:
Checkpoint fractal heap code at a stable point in development. It appears
that adding objects to heaps and reading them back out is now working
properly (as long as there are no gaps in the heap and no standalone objects
are created).
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
Linux 2.4 (mir) w/64-bit & FORTRAN & C++
Solaris 9 (shanti) w/64-bit
Description: cross_read.c is a new program to test reading data created
on an OpenVMS, a little-endian, and a big-endian machine. The three
data files are vms_data.h5, be_data.h5, and le_data.h5. To generate
these data files, run gen_cross.c on these machines and change the file
names.
Platforms tested: fuss and h5committest
Misc. update: MANIFEST
Bug fix
Description:
Previous checkin did a bad thing; 'make clean' failed in example directories.
Solution:
Fixed commence.am so that examples no longer break, and fixed a mistake
in conclude.am.
Platforms tested:
heping (minor makefile change)
Misc. update:
Bug fix
Description:
make check-clean didn't clean results of example tests
Solution:
Fixed Makefiles so that check-clean recurses into example directories.
Also a little Makefile cleanup.
Platforms tested:
mir, modi4, heping, copper
Description: OpenVMS doesn't support denormalized floating-point values.
Disable the denormalized and special values for floating to floating-point
tests.
Platforms tested: OpenVMS - the only concerned machine.

handle more direct blocks from root indirect block.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
Mac OS X (amazon)
Solution: Support VAX float and double types with new byte order. There're some
details not yet included,
1. the alignment detection for VAX order in H5detect.c.
2. support for special values in library conversion functions.
3. the infinity for VAX in H5T_init_inf.
4. support for VAX types in printing hexadecimal format.
Platforms tested: h5committest and fuss.
Code checkpoint
Description:
The fractal heap code is reasonably stable and is passing all its
current tests, so checkpoint everything with CVS.
Also, add "statistics" module for v2 B-trees code, which is only a
stub right now.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Mac OSX (amazon)
Linux 2.4 (chicago)
New features
Description:
Add "find node greater than or equal to key" and "remove first" operations
to skip lists.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Description: By default on VMS system file cannot be opened twice; also
VMS has file versioning. This brakes some of our tests.
Solution:
Tests are commented out with H5_CANNOT_OPEN_TWICE and H5_HAVE_FILE_VERSIONS
that are defined in the vms/h5pubconf.h file only. This change cannot affect
any other platform.
Platforms tested: heping, VMS server
Misc. update:
Bug fix/Feature
Description:
Modify the library to use rand_r, when available, instead of srand. If
rand_r is not available, it will try to use srandom/random, and then finally
fall back to srand/rand.
Solution:
A couple places in the library use the srand() function to seed the random
number generator. This can cause problems on certain platforms and could theoretically
cause problems for users who expect a certain sequence of random numbers following their
own call to srand().
Most platforms have an implementation of rand_r, which is identical to rand, except that
it allows for explicit storage of the seed value. The configure script will now check
for the existence of rand_r to facilitate its use in the library.
Two new functions are added, to replace the macros HDsrand/HDrand. These functions are HDrand and
HDsrand. HDrand will call rand_r, if available, or random(), if available, and fall back to rand() if neither
of those is available. HDsrand will store the seed value locally, if rand_r is available. Otherwise, it will call
srandom if available, and fall back to srand otherwise.
Platforms tested:
heping, mir. Really need to test on Red Storm, since that platform motivated this fix, but the machine
is currently not available.
Misc. update:
Bug fix (sorta)
Description:
Disable the fractal heap tests until I can look into them more thoroughly.
(they are failing on 64-bit machines currently)
Platforms tested:
None - trivial change.
New feature & code cleanup
Description:
Update fractal heap to be able to insert objects into a direct block
hanging off the header.
Extract "octal dump" code into separate routine so that both the local
heaps & fractal heaps can use it.
Other code cleanups & support to get this far.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4
Incrementtal checkin
Description:
Revise & update v2 B-tree code to separate the internal package-specific
routines from the library-callable "private" routines.
Similar updates for the fractal heap code.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Mac OSX (amazon)
New feature
Description:
Check in initial "fractal heap" code, for supporting the group redesign.
Also, remove some remnants of the segmented heap/block tracker/B+tree code
which I didn't find during the last pass.
