Bug fix
Description:
Cygwin was failing (seemingly only when I built in parallel) when it couldn't
find or build H5detect.
Fixed a dependency.
Solution:
H5init.c was depending on H5detect instead of H5detect$(EXEEXT). On Cygwin,
applications end in .exe !
Platforms tested:
mir, cygwin (finrod)

Description: Put in a new API funciton, H5Tis_hard. It checks whether
the conversion function from a native type to another native type is a
compiler (hard) conversion. Also checked a test in test/dt_arith.c.
Platforms tested: h5committest and fuss.

Bug fix & code cleanup
Description:
Fix problem with detecting precision overflows in a more portable way.
(I was depending on the compiler not removing some temporary variables, which
was a bad bet... :-)
Also, hoist the checking for the exception handling routine out of the
inner conversion loop, which should speed up conversions which don't have an
exception handling routine defined.

Bug fix & code cleanup
Description:
Address most of datatype conversion exception handling bug that Ed
Hartnett reported. (He's reported a different problem now, but we're closer
at least).
Also, condense exception handling #ifdef's into one location instead of
spread out in so many places.

Description:

Bug fixes
Description:
This checkin fixes an occasional error on kelgia on sol during distclean.
It also causes test scripts to depend properly on the programs they're
supposed to be testing.
Solution:
The kelgia bug was due to some files being cleaned by automake and manually.
Removed the manual cleaning in src/Makefile.am.
Test script dependencies now need to be specified manually, since the
makefile can't guess what they test from their name. Currently all test
scripts in a given directory have a single list of dependencies--this was
easy and seems to be sufficient.
These dependencies are listed in the SCRIPT_DEPEND variable in the Makefile.am.

heping, mir, modi4, sol

Purpose:
bug fix for collective chunk IO
Description:
When using calloc to allocate an MPI datatype, one should use sizeof(MPI datatype) instead of sizeof(equalivent non-MPI datatype) to assign the value, this causes the problem at 64-bit platforms such IRIX65 and AIX 5.1.

Correct it.

Bug #281
Description:
A dataset created in serial mode with H5D_ALLOC_TIME_INCR allocation setting
was not extendible, either explicitly by H5Dextend or implicitly by writing
to unallocated chunks. This was because parallel mode expects the allocation
mode be H5D_ALLOC_TIME_INCR only.
Solution:
Modified library to allocate more space when needed or directed if the
file is opened by parallel mode, independent of what the dataset allocation
mode is.
Platforms tested:
Heping pp.

Description: Added 2 new configure options, --enable-exception and --enable-accuracy.
--enable-exception lets the library check whether user's exception handling
functions are present during compiler data conversions and use them if they are.
When it's disabled, this step is skipped to improve conversion speed. This
step isn't implemented yet for soft conversions because there would be little
gain in speed.
--enable-accuracy guarantees data accuracy during data conversions. It means
the library will choose compiler conversions only if the accurate data is
secured. Otherwise, the library will go for the library's own conversions. If
this option is disabled, the library uses compiler conversions in favor of
their speed as long as they work even if data can be incorrect.
Platforms tested: h5committest and fuss. Some systems may fail after this
checkin.

Bug fix.
Description:
Reactivated the code for snprintf and vsnprintf for Tflops but added
the SN_SIZ_MIN as an attempt to require the minimum amount of space needed,
hoping vsnprintf/snprintf do not print larger than it per request.

not crashed the application yet.) These are all short term patches.

avoid the problem. (Need to change other similar places when time permits.)

bug fix for collective chunk IO, phase 1
Optimization hasn't been done yet, the collective chunk IO bug should be fixed.
Description:
In chunking storage, memory space and file space will be remapped, So to check
whether file space and memory space are regular in order to use optimized MPI derived
datatype for collective call one has to check per-chunk wise instead of per hyperslab wise.
Even a regular memory space will be stored in span-tree and will be irregular before chunk IO.
Solution:
1. Check file space and memory space per chunk wise instead of per hyperslab wise.
2. For collective IO mode, number of chunks covered by hyperslab may be different. Since we are
handing per chunk per IO, for the extra chunk IO for some(not all) processors, collective mode will
cause program hanged. So for the extra chunk Io mode independent IO has to be used.
3. On some platforms, Complex MPI derived datatype is not working, so we have to use independent IO for collective IO mode if the selection is irregular. However, when the selection is regular, we do want to use collective IO since that will improve performance. Special cares have to be added for this case.
