Update
Description:
Added Flexible Parallel HDF5 support to the ending message that
configure spits out.
Reordered a few other of the messages so that they're in alphabetical
order.
Platforms tested:
Linux
Bug Fix
Description:
Metadata cache in parallel I/O can cause hangs in applications which
perform independent I/O on chunked datasets, because the metadata cache
can attempt to flush out dirty metadata from only a single process, instead
of collectively from all processes.
Solution:
Pass a dataset transfer property list down from every API function which
could possibly trigger metadata I/O.
Then, split the metadata cache into two sets of entries to allow dirty
metadata to be set aside when a hash table collision occurs during
independent I/O.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir) serial & parallel
Misc. update:
Updated release_docs/RELEASE
Bug fix
Description:
The "system scope" for threads isn't supported on all platforms.
Solution:
Add detection of this feature to the configure script and check for
"H5_HAVE_SYSTEM_SCOPE_THREADS" in the appropriate places.
Platforms tested:
modi4 w/threadsafe
New feature for developers.
Description:
Added "function stack" tracing to library. This allows developers (there
is no public API) to call H5FS_print within the library and get a listing
of the functions traversed to reach that point in the library. Eventually,
I may add support for reporting the parameters to each function also...
Mainly for debugging parallel I/O programs, but I think it will come in
handy in other cases also.
The function stack tracking is controlled with a configure switch:
--enable-funcstack, which defaults to enabled currently. When we branch
for 1.6, we should change the default setting on the branch to be disabled.
Also, added a destructor to the thread-specific keys when thread-safety is
turned on in the library. Otherwise, they were leaking memory and causing
difficult to debug errors in threaded programs (like the test/ttsafe test).
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir) w/thread-safety enabled.
Misc. update:
Updated MANIFEST with new files added (src/H5FS.c & src/H5FDprivate.h)
Update release_docs/RELEASE with thread-safety bug fix.
Field Addition
Description:
Added a File ID field to the H5FD_t structure so that, way deep down
in the H5FD_* functions, I'll know what ID the SAP wants for this
particular file.
This is #ifdef'd out so that if you don't have FPHDF5 enabled, then
it won't be there...
Platforms tested:
Linux
Update
Description:
H5FP.c, H5FPclient.c, H5FPprivate.h, H5FPserver.c:
Update. More progression towards the SAP as metadata cache. It
only lacks the ability to take care of metadata allocations.
H5FDfphdf5.[ch]:
Start of a new driver for FPHDF5. Not fully implemented just
yet...
Platforms tested:
Linux
Update
Description:
MANIFEST:
- Added .autom4te.cfg and H5FDfphdf5.[ch] files.
.autom4te.cfg
- When the new versions of libtool/autoconf come out, this file
will help get rid of the annoying autom4te.cache directory.
Platforms tested:
Linux
Update
Description:
version 1.4 has renamed the tool from pio_perf to h5perf.
Folded the chagne into this branch too.
Also updated the Copyright notes.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}? Tested in burrwhite with PP only.
[If no, why not?] It is a pretty straight forward Makefile change.
Update
Description:
Converted the "FUNC_LEAVE" macros to "FUNC_LEAVE_NOAPI" to be
consistent with the rest of the library.
Note: This is probably completely useless as the file is going to go
away with the new model of the SAP as metadata cache...But it helps
me compile...
Platforms tested:
Linux (FPHDF5)
Update
Description:
Added support for defining what the haddr type is in terms of MPI
types.
Solution:
Include some #defines when we typedef haddr...
Platforms tested:
Linux (For FPHDF5 stuff)...
Update
Description:
Changes:
- Added support for the server dumping metadata writes to a
client.
- Some of the code wasn't handling allocated buffers correctly
(freeing twice).
- Modified server so that it handles metadata only.
Platforms tested:
Linux
Update
Description:
Updated the configure scripts. Fortran and C++ didn't have proper
checks for Linux LFS support. Also needed to remove the "-g" flag
from the compile line if --enable-production is set. For that, I took
how it's being done in HDF5 Lite...
Platforms tested:
Linux
bug fix
added more verbose help message
added support for all dataset types
added more error checking
added new output format (28 Jan version )
Platforms tested:
windows , linux
Purpose:
Update H5pubconf.h on both all.zip and all_withf90.zip
Update some project files on all_withf90.zip
Description:

Update some project files on all_withf90.zip
Currently fortran interface failed on windows, may be handled after 1.4 release.
Solution:
Platforms tested:
windows 2000
Misc. update:
Update MANIFEST if you add or remove any file.
Update release_docs/RELEASE for bug fixes, new features, etc.
Update applicable document files too.
Update
Description:
This is the first conversion of the FPHDF5 code to be a metadata
cache. There's an extra error message. I rewrote the sync/change code
to be read metadata/write metadata instead.
I still need to hook these changes into the HDF5 code so that it
looks at the SAP first before checking the file for metadata.
Platforms tested:
Linux
Bug Fix
Description:
When calling H5Fopen with the core VFL driver, but without the
H5F_ACC_CREAT flag goes ahead and creates a memory file.
Solution:
Check for the H5F_ACC_CREAT flag before allowing the memory file to be
created.
Platforms tested:
FreeBSD 4.7 (sleipnir)
Update
Description:
Added description of the configure bugfix for people specifying
--with-*=/usr/include,/usr/lib in their scripts during configure...
Bug Fix
Description:
Some compilers were having problems if we included the -I/usr/include
and -L/usr/lib flags which are completely redundant. This could occur
if the user configured with something like:
./configure --with-zlib=/usr/include,/usr/lib
Solution:
Check if the --with-* command is specified with /usr/include and
/usr/lib. If so, then don't place them in the compile macros.
Platforms tested:
Linux, Modi4
Updated
Description:
Updated Copyright notice.
Replaced HGOTO_ERROR calls involving MPI calls with HMPI_GOTO_ERROR.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}? Tested on Eirene (PP) only since
the code is in the MPIO module only.
patch
Description:
Tflops interprets "$@" as "" when no parameter is given (e.g., the
case of missing file name). Changed it to use $@ till Tflops fixes it.
Platforms tested:
Tflops, burrwhite (pp), modi4(pp)
Bug fix
Description:
Currently, when the library encounters an object header message that isn't
know, it fails to open that object in the file.
Solution:
Allow the library to skip over the unknown object header message and
continue to process the remaining messages, in the hope that the skipped
message isn't important later. If it is important, it will be caught at
a higher level of the library.

FreeBSD 4.7 (sleipnir)

ssize_t getObjnameByIdx(hsize_t idx, string& name, size_t size) const;
// Returns the type of an object in a given group by giving index;
// the overloaded function also provided the object type in text as
// "group" for H5G_GROUP
// "dataset" for H5G_DATASET
// "datatype" for H5G_TYPE
int getObjTypeByIdx(hsize_t idx) const;

When intel compilers (icc, ecc) are used in a linux system, the libtool
