"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)

Too minor to require h5committest (once I pay attention to the compiler
warnings... :-)
Code checkpoint
Description:
Update fractal heap code to allow skipping direct blocks (that are too
small to hold object) when the root indirect block is created.
Platforms tested:

Too minor to require h5committest
New/expanded features
Description:
Check in Peter's changed for the object copy code:

- Start adding framework for property list to control how object
copying occurs.
Platforms tested:

Too minor to require h5committest
Code checkpoint
Description:
Checkpoint recent additions to fractal heap code, which allow for better
support of objects that don't fit into current direct block, requiring
skipped direct blocks to be tracked in free section list.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago & heping)
Linux 2.4 (mir) w/64-bit & FORTRAN & C++

Adding parallel tests for optional collective chunk APIs
Description:
Three new APIs
"H5Pset_dxpl_mpio_chunk_opt_ratio
H5Pset_dxpl_mpio_chunk_opt_num
H5Pset_dxpl_mpio_chunk_opt"
for optional optimization choices from users
have been added to the libraries.
This check-in adds six tests to verify the funcationality and correctedness
of these APIs.
These tests need to be verified with 3 or more processors and with MPI-IO driver only.
Solution:
Using H5Pinsert, H5Pget, H5Pset to verify that the library indeed goes into the branch we hope for.
Using H5_HAVE_INSTRUMENT macro to isolate these changes so that it won't affect or be misused by the application.
Platforms tested:
h5committest(shanti still refused to be connected)
Parallel tests on heping somehow are skipped. Manually testing at heping. Have checked
1,2,3,4,5 processes.
Misc. update:
Code checkpoint
Description:
Check in fractal heap code to add basic support for skipping direct blocks
when an object is too large to fit in one.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
Code checkpoint
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:
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:

Also a little Makefile cleanup.

portibility issue to windows
Description:
setvbuf on visual studio 2005 needs the size to be greater or equal to 2.
<description of setvbuf from msdn library>
Buffer size in bytes. Allowable range: 2 <= size <=
INT_MAX (2147483647). Internally, the value supplied
for size is rounded down to the nearest multiple of 2.
h5import used linebuffer option of setvbuf for stderr and stdout and the size is
0 by default. This causes core dump with visual 2005 on windows 64-bit.
Solution:
1. Use HDsetvbuf inside h5import.c,
2. Define HDsetvbuf inside windows H5pubconf.h for windows to work around
the core dump of h5import test. This is probably a bug inside visual studio 2005.
Platforms tested:
h5committest
windows 6.0 at XP
visual 2005 at XP-64bit
Misc. update:
Description: Unix remove function removes only the latest version of a file
on VMS. Some of our tests create multiple versions of the testfiles
and as a result, test programs may be confused, give false negative result,
etc.
Solution: Created HDremove_all function for VMS that removes all versions of the files.
HDremove on VMS is an alias to HDremove_all.
Platforms tested: VMS server and heping (to check that nothing is borken on UNIX side)

Enhancing the optimiziation of collective IO per chunk
Description:
When the user does one of the following two things:
1. to do collective IO per chunk without using our optimization code
2. or the user passes the percent of number of process per chunk to be 0 when choosing
to do collective IO per chunk
It is not necessary that the library uses MPI-IO collective calls to do any optimization.
Solution:
Modify the code so that no MPI communication-involved analyses will be done for the above cases. Chunk addresses are obtained globally and IO modes are assigned to collective always.
Platforms tested:
h5committest
Misc. update:
Description: Yesterday, H5E_NONE_MAJOR and H5E_NONE_MINOR were added to error
API by hand.
Solution: Today, correct the change by hand with the tool hdf5/bin/make_err.
The change by hand is only in src/H5err.txt.
Platforms tested: fuss - simple change.
Misc. update:
Code cleanup
Description:
Re-alphabetize the POSIX routines (again). Also, add proper prototype
to HDrand() definition.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Bug fix
Description:
There was a duplicate definition for HDsrandom and HDsrand left over in H5private.h
Solution:
Removed the two duplicate definitions.
Platforms tested:
heping (minor change)
Misc. update:
Optimization
Description:
Get rid of unnecessary function call for systems that don't have rand_r.
Solution:
If rand_r isn't present on a system, then macros can be used to simply call
the underlying random function instead of calling the HDrand/HDsrand functions
that keep track of the random seed within the library.
Platforms tested:
heping (minor change)
Misc. update:
Description: Added H5E_NONE_MAJOR and H5E_NONE_MINOR as a major and minor
error message. Their messages are "no error", but because the old library
had them, they're added in for backward compatibility.
Platforms tested: fuss - simple change.
Code cleanup
Description:
Move VAX floating-point definitions down by the other machine specific ones.
Re-work the version handling for VAX byte ordered floating-point numbers.
Version numbers ought to be strictly increasing, not a bit-field.
Platforms tested:
FreeBSD 4.11 (sleipnir)

Description:
Checkpoint fractal heap changes - mostly internal changes to better
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.
New APIs to add for collective chunk IO
Description:
Three new APIs
H5Pset_dxpl_mpio_chunk_opt_ratio
H5Pset_dxpl_mpio_chunk_opt_num
H5Pset_dxpl_mpio_chunk_opt

Solution:
Haven't added tests yet, won't affect other parts of the library.
Will add tests after urgent investigations of memory leaking problems from NASA Aura team.
Platforms tested:
heping: both parallel and sequential

Solution:
Platforms tested: heping, VMS server
Misc. update:
Description:
Two functions (HDsrand and HDrand) are not declared. They caused
compiling errors on Windows. Declare these two functions:
H5_DLL int HDrand();
H5_DLL void HDsrand(unsigned int seed);
Solution:
Platforms tested:
Windows XP and heping
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.
