Add more comments for collective chunk IO supports.
Description:
On some platforms that use mpich library internally, we have no way to check mpich version number. We have to manually turn off the collective IO supports.
One example is Altix(cobalt). Just put a comment there so that we won't forget about this.

Misc. update:
Description:
Added missing member functions:
H5::CompType::getMemberArrayType
H5::CompType::getMemberVarLenType
H5::AbstractDs::getArrayType
H5::AbstractDs::getVarLenType
H5::CommonFG::openArrayType
H5::CommonFG::openVarLenType
H5::PropList::copyProp -- this will replace the current
H5::PropList::copyProp in later releases due
to incorrect prototype.
H5::IdComponent::getHDFObjType
Bug fix
Description:
Correct problems when querying information about a group that was opened
by dereferencing an object reference.
Solution:
Read in symbol table information instead of rely on it being cached.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Bug fix
Description:
If a named datatype is copied and the copy is used to create a dataset,
the dataset would inadvertantly refer to the original named datatype instead
of a local (possibly modified) copy of the named datatype.
Solution:
Fixed datatype copying routine.

Description:
Further progress on fixing file mounting to work properly.

Linux 2.4
Too minor to require h5committest
Description: There was a bug in the calculating code of the Fletcher32
checksum in the library before v1.6.3. The checksum value wasn't consistent
between big-endian and little-endian systems. This bug was fixed in
Release 1.6.3. However, after fixing the bug, the checksum value is no
longer the same as before on little-endian system.
Solution: Made the library compare both the correct checksum and incorrect
checksum generated from v1.6.2 or before. This makes the library be
backward compatible but not forward compatible.
Platforms tested: h5committest and fuss.
Misc. update: Documented the forward incompatibility problem in the
Known Problem section in RELEASE.txt
Bug fix & code cleanup
Description:
Don't unmount child files from a parent file if the parent file is
being held open by an object.
Also, moved the mounting routines into their own source file and the
superblock routines into their own file also.
Solution:
Moved the code for unmounting child files down in the H5F_close routine
and also add checks to the file and group mounting code to unmount child
files when the last object holding open a file closes.
Platforms tested:
FreeBSD 4.11 (sleipnir)
h5committest
Bug fix
Description:
Fixed bugs that caused tests to be unable to find testhdf5.sh during
daily tests, and another that broke sol and shanti.
Solution:
When tests are run, their path is ./$testname .
When scripts are run, their path has no leading "./". Fixed.
Sol and shanti don't recognize the -e option for test, but they do know
-f. Fixed.
Also modified release notes.
Platforms tested:
mir, shanti, heping
Bug fix
Description:
When a series of files is mounted on one another and one of those files
is not unmounted, the library gets confused at shutdown and goes into an
infinite loop in the file interface.
Solution:
If there are still files left in the "closing" state when shutting down
the file API, iterate over those file IDs and unmount any child files that we
find mounted on those files.

Misc. update: First, report a bug fix(#214) of family driver. Second
document PGI compiler bug for optimization on AMD processor.
Description:
When compiler flag was used to set the size of Fortran integer
to 8 bytes, library would fail.
Solution:
Cleaned up the code; added detection of Fortran INTEGER type size
and appropriately defined int_f type for C-stubs routines.
Platforms tested:
Solaris 2.8 32 and 64-bit, AIX 5.1 64-bit parallel
PGI Fortran with -i8 flag on heping
Absoft Fortran with -i8 flag on heping
g95 on mir (Fortran integer is 8 bytes by default that cannot be
changed - compiler bug ;-)
AIX Fortran with -qintsize=8 32 and 64-bit modes on copper
Misc. update:
Bug fix
Description:
Hyperslab selections that had a selection offset and were applied to a
chunked dataset could get into an infinite loop or core dump if the same
selection was used multiple times, with different selection offsets.
Solution:
"Normalize" the selection with the selection offset, generate the
selections for the chunks overlapped and then "denormalize" the selection.

Bug fix/new feature
Description:
Setting "SEMI" or "STRONG" file close degrees causes problems when multiple
file IDs exist for the same file on disk.
Solution:
Make the "SEMI" and "STRONG" settings only apply to the file ID that is
being closed.
Also, add an "H5F_OBJ_LOCAL" flag for the H5Fget_obj_count() &
H5Fget_obj_ids() calls, so that applications can query about objects opened
with a particular file ID instead of all the objects opened in the file on
disk.

h5committest
Description: See details from Bug #213. Family member file size wasn't saved
anywhere in file. When family file is opened, the first member size determine
the member size.
Solution: This is the third step of checkin. h5repart has been modified. If h5repart is used
to change the size of family member file, the new size(actual member size) is saved in the superblock.
In the second step of checkin, multi driver is checked against the driver
name saved in superblock. Wrong driver will result in a failure with an error message indicating
multi driver should be used. This change includes split driver because it's a special case for multi
driver.
In the first step of checkin. Family member size and name template(unused at this stage) are saved
in file superblock. When file is reopened,the size passed in thrin superblock. A different size
will trigger a failure with an error message indicating the right size. Wrong driver to open family
file will cause a failure, too.

Feature
Description:
Added "support" for UTF-8 character encoding.
Solution:
Wrote tests to check that UTF-8 can be used in a number of places in
HDF5 (object names, data, etc.). These tests live in test/tunicode.c.
Added a new UTF-8 character encoding for datatypes.
Platforms tested:
mir, modi4, heping
Misc. update:
Description: h5pget_driver_f function returned information that could not
be interpreted by fortran application
Solution: Defined Fortran global variables that correspond to
the C H5FD_<driver_name> variables at the Fortran library
initialization time.
Platforms tested: heping with PGI compilers, sol 64-bit and copper parallel
Misc. update:
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: Added missing h5get_member_class_f function
Solution:
Platforms tested: heping; it is a simple change. I will
watch daily tests and take care of failures.
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:
Optimization
Description:
Speed up I/O on enumerated datatypes (including those nested in compound
datatypes, arrays, etc.) if the destination datatype is a proper superset of
the source datatype.
Solution:
Detect the situation and treat as no-op datatype conversion.

Automake update cleanup and minor changes
Description:
Removed macros in acsite.m4 that are no longer used.
Switched to using autoconf's AC_LANG_PUSH(Fortran) instead of old
AC_LANG_FORTRAN9X macro.
Switched to using AC_LANG_PUSH() and AC_LANG_POP() (from old AC_LANG_X).
Added ifort to list of Fortran compilers configure will look for.
Added a note about automake change to Release Notes.
Platforms tested:
copper, modi4 (parallel and serial), eirene
Description: Support of hardware conversion between "long double" and integers(mainly in
H5Tconv.c) and test cases for it(mainly in dtypes.c)
Platforms tested: h5committest and fuss
Misc. update: RELEASE.txt
Description: H5Tget_member_value didn't return correct value if called after
H5Tenum_valueof. It's because there's a sorting on the members of enum type in
H5Tenum_valueof which changed the order of members.
Solution: Made a copy of original type and do sorting on it to protect the
original order.
Platforms tested: fuss; tested v1.6 with h5committest
Misc. update: RELEASE.txt
Description: For variable-length string, H5Tget_class returned H5T_STRING as
its class. But H5Tdetect_class and H5Tget_member_class considered it as
H5T_VLEN. This is fixed to let all these 3 functions treat it as H5T_STRING.
Some test cases have been added to dtypes.c
Platforms tested: heping - already tested for v1.6 with h5committest
