Description: Removed support for SRB driver
Solution: Removed or modified appropriate files; ran reconfigure
to regenerate Makefile.in and configure files.
Platforms tested: heping and shanti
Misc. update: ran bin/chkmanifest on heping
Description: Split test/dtypes.c because it's so big. Moved all integer-integer,
floating-floating, integer-floating, floating-integer, derived integer, derived
floating conversion tests to a new test program, dt_atomic.c. The test remains
the same basically.
Platforms tested: fuss and h5committest
Misc. update: MANIFEST
add a new feature for the test image API, read a palette from an ASCII file and attach several
palettes to an image

Misc. update:
New feature
Description:
Add first iteration of "segmented heap" code, which will be used to store
links in groups in a more flexible way than the previous "local heap" mechanism.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Solaris 2.9 (shanti)
add 1 test that reads realistic dimension scales data from an ASCII file and generates an hdf5 file with DSs

Misc. update:
Update MANIFEST for windows project files.
Description:
Many windows project files are added into CVS. MANIFEST needs to be updated.

Misc. update:
Purpose:
Added C++ wrapper for Packet Table API.
Description:
Added macro for high-level C++ library (LIBH5CPP_HL), which changes every
Makefile.in.
Added directories for high-level C++ library (though currently only Packet
Table API is supported).
Added both C++ source and tests.
Platforms tested:
sleipnir, mir, modi4
Misc. update:
Added Packet Table to high-level APIs
Description:
The Packet Table is an API that allows the user to append records
("packets") to a table, and read the back again. It supports
fixed-length records with a defined datatype and variable-length
records. It also supports a "current record" index to track the
user's position in the table.
Solution:
The Packet Table code lives in hl/src, and its tests in hl/test.
Some code is shared between the H5TB table and the H5PT Packet Table
in the form of functions in H5HL_private.c.
Some documentation exists for a previous version of the API. Updated
documentation and C++ wrapper API coming soon.
Platforms tested:
sleipnir, eirene, copper, modi4
Description: Somehow, the hardware conversions between "long double" and other native floating-point
types were left out.
Solution: Added the hardware conversion functions in H5Tconv.c and test cases in dtypes.c.
Platforms tested: h5committest and fuss.
Misc. update: updated MANIFEST to replace bin/reconfigure.sh with bin/reconfigure
feature
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.
Platforms tested:
verbena,copper,shanti
Misc. update:
MANIFEST
New feature
Description:
Expand v2 B-tree code to support splitting the root node when enough
records are inserted and move metadata cache callbacks into their own source
file.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Too minor for h5committest
New feature
Description:
Add basic code for new B-tree implementation. They don't do much yet,
aren't hooked up to anything yet and the format may change, but I'd like to
start getting them into the daily tests.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Too minor to require h5committest
Bug fix
Description:
Two files in the bin directory didn't make it into CVS.
Solution:
Added depcomp and compile to CVS repository.
Platforms tested:
Already testsed with these files.
Configuration feature
Description:
HDF5 now uses automake to generate Makefiles
Solution:
Makefile.in files are now generated from Makefile.am files.
To reconfigure (after chaning a Makefile.am or configure.in):
/bin/sh bin/reconfigure.sh
Platforms tested:
Many
added a first batch of dimension scales
fix some small bubgs in lite (a close function was not being called )
Description:
this batch contains the basic API functions described in the RFC and a minimal test file

linux
solaris 64

windows
Misc. update:
changed the name of the hl table files back to H5TB.c and H5TB.h
this can be done now because the H5TB.c (threaded binary trees) file was removed from the hdf5 library
Description:
Solution:
Platforms tested:
linux
Misc. update:
Description: Removed PABLO from the source
Solution:
Platforms tested: arabica with 64-bit, copper with parallel,
heping with GNU C and C++ and PGI fortran (but
I disabled hl, there is some weird problem only
on heping: F9XMODFLAG is not
propagated to the Makefile files
Misc. update:
A new configuration file hdf5/config/i686-pc-cygwin is add for HDF5 on Cygwin. So MANIFEST should be updated to include this file.

Misc. update:
Remove feature
Description:
Retire threaded, balanced binary tree code from HDF5 use. Requiescat in
pace...
Also, regenerate dependencies files.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require full h5committesting (the code is already
disconnected from everything except its 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".
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel & fphdf5
FreeBSD 4.10 (sleipnir) w/threadsafe
FreeBSD 4.10 (sleipnir) w/backward compatibility
Solaris 2.7 (arabica) w/"purify options"
Solaris 2.8 (sol) w/FORTRAN & C++
AIX 5.x (copper) w/parallel & FORTRAN
IRIX64 6.5 (modi4) w/FORTRAN
Linux 2.4 (heping) w/FORTRAN & C++
Misc. update:
Modify the cache code (H5C) to support automatic cache resizing to
adapt to the work load at run time.
Description:
Different applications require different sized caches to maintain
an acceptable hit rate. This set of changes attempts to provide the
ability to adjust to circumstances automatically.
Solution:
Added highly configurable code to allow the user to either set a
fixed cache size, or allow the cache to grow and shrink according to
conditions.
If enabled, cache size increases are triggered when the hit rate
drops below a user specified threshold in a user specified interval.
Cache size reductions (if enabled) are triggered when either the
hit rate exceeds some user specified threshold over a user specified
interval, when the cache contains "enough" entries that haven't been
accessed for a user specified interval, or some mix of the above.
See the header comments on the H5C_auto_size_ctl_t structure in
H5Cprivate.h for further details.
At present, the cache resize configuration options are not
accessible via the user API. Must add this.
Platforms tested:
h5committested, hepingi (serial), and copper (parallel)
Misc. update:
Port
Description:
Initial work for supporting GNU FORTRAN/F95 on FreeBSD. I think I've
got things mostly set up correctly, but I'm getting an internal compiler
error on one of the FORTRAN sources, so I'm not going to add this configuration
to the daily tests yet.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/GNU FORTRAN
Not tested in h5committest
add hl fortran
Description:
Solution:
Platforms tested:
linux (absfot and pgf90)
solaris (32 and 64 bit)
AIX
note : HP gives a compiling error , to be fixed in the future
Misc. update:
Add new internal data structure
Description:
Add an implementation of skip lists to the library (see comment in
src/H5SL.c for references to the papers describing them) as a potential
replacement for our current threaded, balanced binary tree container.
Skip lists are much simpler to implement and should be faster to use.
Also, added new error codes to release branch, so bump the minor version
number to indicate that the library is no longer perfectly compatible with
the 1.6.3 release.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Solaris 2.7 (arabica)
Too minor to require further testing (the skip lists aren't actually
used by any library code yet)
