Bug fix
Description:
Handle denormalized floating-point values in a more general way that
uses a different 'epsilon' for determining if two values are "close enough"

Update DEC compiler support
Description:
Updated DEC/Compaq compiler detection to handle DEC->Compaq switchover
in compiler version string.
Also, copied v5.x compiler flags to V6.x compiler flags and included the
-ieee and -misalign flags necessary for correct floating-point support.

Bug fix
Description:
C++ compiler was choking on passing a (hsize_t *) to a function which wants
a (uint8_t *).
Solution:
Cast the (hsize_t *) to a (uint8_t *)... :-)

Omnibus floating-point bug fix changes
Description:
There are a number of problems in the floating-point conversion code that
were exposed by Ray's recent int<->float checkin:
- The 'my_isnan' code in test/dtypes.c was broken and would always return
true. The meant that the actual values in the float<->float conversion
tests were _never_ checked, hiding the other bugs included in this
checkin.
- A recent change I made to the type conversion code used "FLT_MIN" instead
of "-FLT_MAX" for the most negative 'float' value for the double->float
conversion, which meant that any the negative number that was converted
from a double to a float would have been mapped to zero, essentially.
- A change that Robb appeared to have made ~2.5 years ago to the "generic"
float->float conversion routine appears to be incorrect and I've backed
it out.
- Floating-point conversions on SGI's which converted denormalized values
would be mapped to zero instead of being propertly preserved in the new
type. This was addressed by an SGI-specific system call to prevent the
behavior.
Solution:
Described above, generally.

Description: data type conversion between integers and float numbers.
(Cover your ears. It's going to explode.:)
Solution: covers all native type conversion. Mainly uses hardware
conversion but handles overflow more gracefully.

Bug fix
Description:
Our previous "optimization" of metadata writing which only wrote metadata
from one process was abusing MPI-I/O and after some consultation with Rob Ross
and Rajeev Thakur, Albert & I have come up with a solution...
Solution:
Instead of only writing from one process, issue a collective write
operation with all processes, for metadata writes.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
new feature
Description:
Added the -setup option so that it can setup the snapshot test
directory structure. This will help the setup of snapshot test
in a new machine, especially remote machine much easier.
Platforms tested:
no h5committest becuase it does not test this script.
Tested in tg-ncsa.
Improvement
Description:
The cvs checkout used the complete path of current/ which is not
accepted by cvs server. Changed it to chdir to the snapshot directory
and then cvs checkout just current/.
Platforms tested:
Not h5committested because it does not test this command.
Tested in tg-ncsa which has no direct access to the CVS directory
and must use the server route.
Misc. update:
Bug fix
Description:
If using g++ on HP-UX, the flags for aCC would be placed on the
command line. This was causing g++ to fail the configuration test.
Solution:
CHanged the test so that it's a case statement. If it's the aCC
compiler, then use those flags. Otherwise, don't specify flags. This
case statement can be modified to provide compiler-specific flags in
a similar way to other config/* files.
Platforms tested:
Hp-UX (Hp-UX specific change.)
Misc. update:
Bug Fix
Description:
The FFLAGS, CXXFLAGS, and CPPFLAGS variables weren't carrying
user-defined values into the Makefiles.

Update
Description:
This completes Phase I of the FPHDF5 testing. This test does the
following:
- Creates a file
- Creates multiple non-root groups
- For each process:
For each non-root group:
Create multiple datasets
Access all datasets created above
Write to all datasets created above
- Close the file
- Reopen the file and verify the data is correct

The SAP was sending back replies to the client but the client wasn't

Misc. update:
Bug fix.
Description:
The new routines added for H5MM_[m|c]alloc were causing the function
stack code to infinitely recurse while allocating room for the thread-specific
information (when thread-safety was turned on).
Solution:
Call HDmalloc directly instead of H5MM_malloc
Platforms tested:
FreeBSD 4.9 (sleipnir)
Changed are not tested in h5committest
Bug fix
Description:
Variable length strings and sequences with NULL pointers were not handled
by library, causing problems access the data. This also affected fill values
for variable-length datatypes.
Solution:
Address the issues in the library by detecting NULL sequences/strings
and avoid trying to convert them.
Patched up dumper to display NULL sequences/strings.

Description:
Added tests of 1wMr with options to apply Atomicity or File_sync.

Description:
Extensive reworking of the code. More modular now. Tests for almost
all of "Phase 1"s requirements. Need to check that data is correct
after reopening the file.

FPHDF5-specific fixes...No need for H5committest
Misc. update:
Bug fix and File Addition
Description:
- Fixed when reading from the file with FPHDF5. It wasn't recording
how many bytes it read.
- Added Arithmetic Transformation modules. These haven't been
included into the HDF5 build. I just added them here for future
porposes...
Solution:
Added a call to "MPI_Get_count" to get the number of bytes read.

Misc. update:
Bug fix & code cleanup
Description:
Allowing the library to call malloc with a size of 0 bytes causes problems
for some users, so we check for allocations of 0 bytes and disallow them now.
Cleaned up some code which could call malloc with 0 size.
Changed some code calling HDmalloc directly to call H5MM_malloc(), which
allows us to check for 0 sized allocations.

Description:
Improved integer & floating-point datatype conversions by removing some

convert backwards, switching to algorithm which computes the non-overlapping
space in the buffer and repeatedly converts it in the forward direction.

Improvement
Description:
If the library is built in parallel mode, then name the "h5cc" and
"h5fc" programs "h5pcc" and "h5pfc" resp. This saves the user from
worrying about mixing serial and parallel builds of the library and
having to specify the pathnames and so-forth.
Platforms tested:
Linux (w/ parallel & Fortran)
Modi4 (w/ parallel & Fortran)
Sol (Serial & Fortran & C++)
Misc. update:
Updated release/docs/RELEASE
Update
Description:
Modified the FPHDF5 test so that a single process creates multiple
datasets in a non-root group then all of the processes (sans the SAP)
access it.
Modularized the code a bit more to make it easy to perform the above
tests.
Changed the code a bit so that >3 processes can (theoretically) be
used to test this.
