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:
Description: The 6th step of changing conversion test. This checkin is
only for conversion of special values from floating-points to integers.
Solution: This test is seperated from regular value conversion. It reuses
the same function test_conv_int_float() in test/dtypes.c. The source buffer
of floating-point type is filled up with 8 special values, +/-0, +/-infinity,
+/-QNaN, +/-SNaN.
Also added 3 new conversion exception values H5T_CONV_EXCEPT_PINF, H5T_CONV_EXCEPT_NINF,
H5T_CONV_EXCEPT_NAN, for floating-point special values positive infinity, negative
infinity, and NaN. These values are for conversion exception callback function defined
through H5Pset_type_conv_cb(). (Remember to update the document!)
Platforms tested: h5committest
New feature & code cleanup
Description:
Add feature to find first block >= a certain size (useful for allocating
space)
Cleaned up various comments, etc.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
Description: The 5th step of changing conversion test. This checkin is only for conversion
of special values between floating-point types.
Solution: This test is seperated from regular value conversion. It reuse the same function
test_conv_flt_1() in test/dtypes.c. The source buffer of floating-point type is filled up
with 8 special values, +/-0, +/-infinity, +/-QNaN, +/-SNaN.
Platforms tested: h5committest, fuss, and modi4.
New feature & bug fix.
Description:
The scaleoffset filter was not completed at last check-in and had quite
a few bugs.
Solution:
The scaleoffset filter is now complete for compressing integers. All previous
bugs have been fixed. The filter does not compress floating-point at present.
The filter only supports integer and floating-point datatypes.
Platforms tested:
heping, copper, shanti
Misc. update:
Description: The recent change of conversion between floating-point and floating-point types in dtypes.c have
detected some bugs in H5T_conv_f_f in H5Tconv.c.
Solution: This checkin is to fix these bugs. They happened in a few places in H5T_conv_f_f causing incorrect
rounding, denormalization, etc.
Platforms tested: h5committest and modi4
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.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Bug fix
Description:
Opening an object in a group that is located in a file which has been
unmounted would cause a core dump. :-(
Solution:
Re-arrangement internal code to compute internal "user" and "canonical"
names for the newly opened object in a safer way.
Platforms tested:

Update comments
Description:
Correct some minor errors in comments/error strings.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Solaris 2.9 (shanti)
Purpose:
Bug fix
Description:
Calling H5Iobject_verify on an invalid type of ID (e.g., H5I_BADID) triggers
an assert.
Solution:
Test for this condition and return an error instead of an assert.
Added tests for this case.
Platforms tested:
sleipnir (minor change)
Configure feature
Description:
On some platforms with some compilers, automake's dependency tracking
is silently disabled. This can be confusing for developers.
Solution:
Set configure to enable dependencies all the time unless the user
explicitly disables them (using the configure flag
--disable-dependency-tracking) or a site file overrides the default
(as is the case on IRIX).
Platforms tested:
sleipnir, mir
New feature/tests
Description:
Add better support & tests for removing blocks being tracked.
Platforms tested:
FreeBSD 4.11 (sleipnir)

Description:
Add some internal validation routines and make certain that the max & min
block sizes get tracked accurately, at least for a simple series of insertions
Platforms tested:
FreeBSD 4.11 (sleipnir)

New feature & bug fix
Description:
Support inserting multiple blocks
Start tracking the metadata about the blocks.
Platforms tested:

New feature & bug fix
Description:
Allow NULL 'op' for find operations to easily query the existance of a
record for a key during H5B2_find() operations.
Fix H5B2_neighbor() to work properly with empty B-tree
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
New feature
Description:
Add new "block tracker" data structure to library, for tracking blocks of
bytes in a file. Block trackers will be used to keep track of the blocks
belonging to the soon-to-be-implemented "segmented heap" which is designed to
replace the current local & global heaps (starting with the local heap).
Block trackers will also keep track of the free space in the segmented heap
and someday could be used to track the free space in the entire HDF5 file.
They are implemented as a small header of information to cache the state
of the blocks (max & min sizes of blocks tracked, etc.) and the records of
the blocks themselves are stored in a v2 B-tree.

cache was requested, but only a read lock is necessary.
Add routine to find nearest neighbor record < or > to a query key.
Platforms tested:

Bug fix & new tests
Description:
Fix another couple of issues with record removal and add some more tests to
make certain removals work correctly.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
Bug fix & new tests
Description:
Fix several errors in record removel routines, which should now be feature
complete for removing records at any location in the B-tree (further testing
will verify this)
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
New feature.
Description:
The nbit filter does not support situations where datatype of string,
time, enum, variable-length, bitfield, opaque, reference is a field of
a compound datatype or array datatype.
Solution:
Modify the nbit filter to hanle such situations. The filter is a no-op
to these dataytypes.
Platforms tested:
copper, heping.
Misc. update:
Bug fix
Description:
Corrected errors in record removal code to handle removing records in
higher nodes in the B-tree.

Automake version upgrade
Description:
Upgraded automake version from 1.6.2 to 1.9.5.
Changed bin/reconfigure script to use automake 1.9.5.
Changed configure.in and Makefiles to use new FCFLAGS and FC variables
instead of FFLAGS and F9X.
Automake and configure should now do the lion's share of the work
supporting Fortran 9X; macros in acsite.m4 are now mostly unused (will
be cleaned later).
Altered how configure handles pmake; now root-level Makefile.in is
processed by bin/reconfigure to have a .MAKEFLAGS target, since
automake no longer allows us to define unused variables.
Configure now always checks for C++ compiler even if it is not
used, since automake thinks this is the Right Thing To Do and
will break otherwise.
Platforms tested:
Sol, copper, heping, mir, sleipnir, eirene, pommier, kelgia, modi4.
Bug fix & new feature
Description:
Allow B-tree's height to be reduced when removing records.

Bug fix & new feature
Description:
Fix error in 3-node redistribution when nodes are only moving into the
middle node from the left & right nodes (which happens sometimes during
record removals).
Clean up internal insert & remove routines to remove lots of redundant
checking.
Added 3->2 node merge routine to handle more record removal cases.
Platforms tested:
FreeBSD 4.9 (sleipnir)
Solaris 2.11 (shanti)
Bug fix & new feature
Description:
Fix a couple of off-by-one errors in assertions (code was actually correct)
for 3 node redistributions.
Remove "old" node removal code that is unused now.
Add more tests that verify that 2-node and 3-node redistributions are
working correctly for removals.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
Bug fix
Description:
Filter callback routines were being called with memory "version" of disk
datatype (don't ask... :-), which could result in incorrect calculations in
the filter callbacks.
Solution:
Rearrange code to call the filter callbacks after the final disk "version"
of the disk datatype has been created.

Bug fix
Description:
The GASS VFL driver header file was bringing in the <string.h> header file,
which several other source code modules needed also, but weren't including
