Description: Reverse the 3rd step of change just checked in yesterday(revision 1.155) because of some errors
in daily test. Use the revision 1.154 for now until the problem is fixed.
Platforms tested: fuss - simple rolled back to previous revision.
New tests
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)
Solaris 2.9 (shanti)
New feature & bug fix
Description:
Support inserting multiple blocks
Start tracking the metadata about the blocks.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
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.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
h5committest
Description: This is the 3rd step of change conversion test. This checkin is
only for conversion from floating-point to integer.
Solution: The source buffer is filled in with normalized and denormalized
floating-point values. For the normalized values, it starts from FLT(DBL, or
LDBL)_MIN, multiplied by 10(10000 for double, 100000000 for long double) for
the next value, until reaches to FLT_MAX. For denormalized values, the
exponent part is always 0. Mantissa part starts with 000...001, 000...011,
000...111, until reaches to 111...111. The same is with negative values.
Platforms tested: h5committest and fuss.
Bug fix & New feature
Description:
Correct some situations where a write lock on the data in the metadata
cache was requested, but only a read lock is necessary.
Add routine to find nearest neighbor record < or > to a query key.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
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)
Description: This is the 2nd step of changing conversion test. This checkin is
only for conversion from integer to floating number. The source buffer of
integer is filled up in the same way described in the last checkin(revision
1.153).
Platforms tested: fuss, sol, and heping - copper was down. Couldn't do
h5committest.
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)
Bug fix
Description:
Corrected errors in record removal code to handle removing records in
higher nodes in the B-tree.
Platforms tested:
FreebSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
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.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
More tests
Description:
Add tests for removing records in the root of a level-1 B-tree and
promoting and merging leaf nodes.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
Bug fix/new feature
Description:
Tweak the record promotion algorithm to get it working correctly when
promoting and redistributing records.
Added tests for that case.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
New feature
Description:
Allow records in internal nodes to be removed, not just records in leaf
nodes.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
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)
Description: This is the first step of changing conversion test. This checkin is only for conversion
between integers. Instead of filling source buffer with randomly generated bit pattern, this new way
uses more sensible bit patterns. It's easier to see using "char" as source for example. The bit patterns
will be
00000001, 00000010, 00000100, 00001000, 00010000, 00100000, 01000000, 10000000
00000000, 00000011, 00000111, 00001111, 00011111, 00111111, 01111111, 11111111
11111111, 11111110, 11111100, 11111000, 11110000, 11100000, 11000000, 10000000
The main point of this way is to avoid casting and comparison between source and destination types by
compiler. The bit patterns will cover positive maximum and minimum, negative maximum and minimum if
the source is signed integer.
Platforms tested: h5committest and fuss.
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)
New test
Description:
Add a couple more tests for removing records before I start modifying the
code further.

New features & refactor
Description:
Add basic record removal (only handles level-0 B-trees currently)
Add query routine to check the number of records in a B-tree
Add debugging routine to check the address of the root node in the B-tree
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
Description: Somehow, the hardware conversions between "long double" and other native floating-point
types were left out.
Solution: Added the hardware conversion functions in H5Tconv.c and test cases in dtypes.c.
Platforms tested: h5committest and fuss.
Misc. update: updated MANIFEST to replace bin/reconfigure.sh with bin/reconfigure
Description: The library didn't handle incorrect hardware conversion for datatype. It simply did
convert to incorrect data if any hardware didn't handle correctly.
Solution: During configuration, incorrect hardware conversion is detected and some macros are
defined. Use these macros to decide whether to register hardware conversion in H5T.c. If no hardware
conversion function is registered for certain pair of datatypes, software conversion function will
be used as the conversion path. Although slower than hardware conversion, we're more confident
software conversion is accurate.
So in one sentence to describe library's behavior, if some hardware conversion doesn't work well,
software conversion will be used instead.
Platforms tested: h5committest and fuss.
Misc. update: some changes to configure's comments.

Solution:
Platforms tested:
heping, copper, arabica
Misc. update:
Purpose:
Bug fix
Description:
modi4 dies during build with strange errors.
The root cause of these is a two-year-old hack in HDF5's libtool
script that only takes effect on IRIX.
Solution:
Edited the libtool hack (by editing ltmain.sh) to correct a bug in
the hack.
Also made sure that compiler-specific DEFAULT_LIBS are used
when linking.
Platforms tested:
sleipnir, copper, modi4, sol
