Bug fix.
Description:
getenv_all, like some implementations of getenv, keeps an internal buffer
for the getenv values. Application must make a copy of the content of the
returned pointer before calling getenv_all again IF it wants to use the
first content later. The previous code violated this rule and caused
error.
Solution:
Did a small revamp of the h5_fixname to fix the above problem by moving
the getenv_all for HDF5_NOCLEANUP eariler to avoid it clashing the
call of getenv_all for HDF5_PARAPREFIX. No a good permenant fix. Need
to really recode this routine.
Platforms tested:
h5committested.
Bug fix.
Description:
getenv_all will be called even when it is NOT an MPI application.
Solution:
Moved the use of getenv_all("HDF5_NOCLEANUP") to fix_name so that it will
be invoked only if a parallel driver is used.
Platforms tested:
hand tested in copper.
bug fix 504
Description:
testpar/t_mpi would hang if $HDF5_NOCLEANUP is set. E.g.,
% env HDF5_NOCLEANUP=yes mpirun -np 3 ./t_mpi
This happened because the environment variables are not exported to all
mpi processes by the mpirun command. So, some attempted to do cleanup
while others don't and some hang waiting for others to act.
Solution:
Instead individual program checking getenv, they all just called h5_cleanup
no matter. h5_cleanup now uses getenv_all to check the $HDF5_NOCLEANUP if
it is in parallel mode.
Platforms tested:
h5committested, tested pp in heping too.
Feature
Description:
Added character encoding and attribute creation property lists.
Solution:
Attributes' character encoding is set via the ACPL.
The default is ASCII, with UTF-8 being the other option currently.

Bug fix
Description:
Retrieving an object's name could fail (in various ways) under certain

Bug fix
Description:
Fortran type generation was broken in two ways. Fixed both.
Solution:
Firstly, there were a couple of path problems. Fixed a typo and
specified the full path of a file.
Secondly, the dependencies weren't right when building with HDF5-specific
commands (make lib, make check-s, etc.). Tweaked dependencies
to fix the problem.
Platforms tested:
mir, modi4, sleipnir
Configure feature
Description:
Added 'make trace' target.
Solution:
Added tracing to 1.7. This was done automatically in 1.6, but left out
of 1.7 until now (oops!).
Tracing in 1.7 only happens manually, when the user types 'make trace.'
Tracing automatically requires more framework than it's worth.
I also fixed a couple of tracing bugs and ran trace.
Platforms tested:
mir, sleipnir, modi4
Misc. update:
Bug fix
Description:
Before this checkin, 'gmake check-s' would fail if there was a file in
the current directory named 'check-s'.
This is fixed under gmake (not sure how to fix for other makes).
Solution:
check, progs, install, etc. are what gmake calls "phony" targets,
which means that no file should be created. These targets can be
specified by a line of the form
.PHONY: check progs install ...
Automake adds this line for targets it knows about, but HDF5 has a
lot of custom rules. This checkin adds a .PHONY line for those rules.
I believe that only gmake recognizes the .PHONY line (at least, pmake
doesn't seem to), but a partial solution is better than none.
This error should occur very rarely anyway (the user has to manually
create files with names like 'build-check-s' or '_test').
Platforms tested:

Bug fix
Description:
Fixed bug in hl/src Makefile that was deleting y.tab.c.
Running bin/reconfigure changed a few other files as well (somebody
probably updated Makefiles.am but forgot to bin/reconfigure).
Solution:
Automake in its wisdom adds the line "rm *.tab.c" to every distclean
in every directory. I assume that it assumes that such files are
generated during the build. Supplied an empty distclean-compile
target to remove this line from the Makefiles.in.
Platforms tested:

New feature
Description:
Check in baseline for compact group revisions, which radically revises the
source code for managing groups and object headers.
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!

This initiates the "unstable" phase of the 1.7.x branch, leading up

be able to read your old files!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
Solution:
There's too many changes to really describe them all, but some of them
include:
- Stop abusing the H5G_entry_t structure and split it into two separate
structures for non-symbol table node use within the library: H5O_loc_t
for object locations in a file and H5G_name_t to store the path to
an opened object. H5G_entry_t is now only used for storing symbol
table entries on disk.
- Retire H5G_namei() in favor of a more general mechanism for traversing
group paths and issuing callbacks on objects located. This gets us out
of the business of hacking H5G_namei() for new features, generally.
- Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t
- Lots more...
Platforms tested:
h5committested and maybe another dozen configurations.... :-)
New feature
Description:
Add in baseline "object copy" code from Peter [in the form of a new API
routine: H5Gcopy()]. There's still some work to do (like handling variable-
length datatypes and possibly support for references) and it hasn't been tested
on mounted files yet, but the core functionality is there and working
correctly.
I've also got a set of patches to update the 1.6 branch with tweaks to
keep the branches mostly in sync, but Elena will kill me if I import them
before the 1.6.5 release is out... :-)

Bug fix/feature
Description:
Added support for -shlib in h5fc and h5c++.
Made check-install use -shlib when only shared libraries have been installed.
Solution:
h5fc and h5c++ didn't recognize -shlib. Stole code from h5cc to link against
shared libraries.
When static libraries are disabled, the examples Makefiles will automatically
use the -shlib option to link against shared libraries. Thus,
--disable-static and make check-install should work together.
Platforms tested:

Bug fix
Description:
Failed parallel tests now cause make to exit with an error.
Solution:

Added additional targets to build-all
Description:
Surveyed files to find out which ones are not built.
Added test/space_overflow and perform/benchpar to programs built with
--enable-build-all.
Discovered that tools/misc/pdb2hdf5 and tools/misc/h5import were
obsolete and deleted them.
Platforms tested:
mir, modi4, sol
Misc. update:
Update of release file and removal of --enable-pdb2hdf5 to follow.
Bug fix
Description:
test/gen_new_fill.c used some old APIs that didn't compile with the current
library. Brought it up-to-date.
Some other files (test/gen_old_*) are designed to be compiled only
with older versions of the library. Removed rules to try to build
them in the current Makefiles.
Platforms tested:
mir
Bug fix
Description:
Changed configure.in to use an environment variable TR to set the path
to the tr utility.
Solution:
There are two kind of tr on Solaris with slightly different syntax.
HDF5's configure relies on the "standard" tr. Traditionally, HDF5ers
have needed to make sure that the "right" tr was found before the
wrong one in their path; now they can use an environment variable.
Platforms tested:
mir, shanti, sol
Misc. update:
Forgot to update release notes. Off to do that now.
Bug fix
Description:
Changed the name of a file from the last fix.
createnoenc.c is not gen_noencoder.c
Solution:
This is just a more standard name for the file.
Platforms tested:
tested in previous check-in; forgot to commit to cvs.
Makefile bug fix
Description:
Previously, automake didn't output rules to build perform/mpi-perf or
the test/gen_* programs.
Now these can be built by typing 'make mpi-perf' (or 'make foo') or by
configuring with --enable-build-all.
Solution:
Automake doesn't like having rules for programs it doesn't build. Tricked
it by having these programs built "sometimes"--whenever the user enables
--build-all. This should be used mostly for testing and to ensure that
these helper programs compile.
***IMPORTANT***
These programs do *not* currently compile. When --enable-build-all is used
(not the default), gen_new_fill fails because it uses an old API. This is
an existing "bug" that has simply been exposed by this checkin.
Platforms tested:

Too minor to require h5committest
bug fix.
Description:
When a parallel test script test fails, make would continue because the
way it was setup inside a for loop. Fixed it by issuing an exit 1 inside
the loop.
There was also a typo error in the newer command comparision that it
must be $${chkname} in order to be valid. Also, the test script itself
was not checked in the newer lists. All fixed.
Platforms tested:
h5committested and also hand tested in heping pp mode.
Repair synchronization bug in the metadata cache in PHDF5
Also repair numerous other bugs that surfaced in testing the
bug fix.
Description:
While operations modifying metadata must be collective, we allow
independant reads. This allows metadata caches on different processes
to adjust to different sizes, and to place the entries on their dirty
lists in different orders. Since only process 0 actually writes
metadata to disk (all other processes thought they did, but the writes
were discarded on the theory that they had to be collective), this made
it possible for another process to modify metadata, flush it, and then
read it back in in its original form (pre-modification) form. The
possibilities for file corruption should be obvious.
Solution:
Make the policy that only process 0 can write to file explicit, and
visible to the metadata caches. Thus only process 0 may flush dirty
entries -- all other caches must retain dirty entries until they are
informed by process 0 that the entries are clean.
Synchronization is handled by counting the bytes of dirty cache entries
created, and then synching up between the caches whenever the sum
exceeds an (eventually user specified) limit. Dirty metadata creation
is consistent across all processes because all operations modifying
metadata must be collective.
This change uncovered may bugs which are repaired in this checkin.
It also required modification of H5HL and H5O to allocate file space
on insertion rather than on flush from cache.

Description:
On VMS dsets test failed screaming about corrupted stack.
Debugging didn't show any obvious problems. Careful examination
of compilation warning messages (something like "function is used as

It turned out that two variables H5Z_SET_LOCAL and H5Z_CAN_APPLY
were confused with H5Z_set_local and H5Z_can_apply functions from

Solution:
Changed variable names to H5Z_SET_LOCAL_TEST and H5Z_CAN_APPLY_TEST.

Description:
Disabled C++ shared libraries for Sun Workshop compiler.
Solution:
This bug only seems to happen when using the -xarch=v9 flag to compile in
64-bit mode, but disabling shared libraries entirely for this compiler is
an easier fix (I don't know how to detect 64 bit mode from the command line).
The framework for disabling shared libraries for other C++ compilers is
in place.

Bug fix/feature
Description:
Disabled shared libraries for a number of Fortran compilers that don't

Fortran supports shared libraries. It is set in configure.in.
Platforms tested:
mir, sleipnir, colonelk, heping
Description: H5T_register() replaces any existing data conversion path
with a new path.
Solution: Added a parameter to H5T_register() and H5T_path_find() to
signal the library whether the new conversion path is from API function
H5Tregister() or from private function like H5T_init_interface(). If it
is from H5Tregister(), replace existing path. If it's from H5T_init_interface()
and the library is trying to register default hard conversion functions,
don't replace existing path because the path is registered by the library.
For example, the library registered H5T_conv_int_float() and is trying to
register H5T_conv_long_float(). The size of long is equal to int. There's
no need to replace the path H5T_conv_int_float().
Platforms tested: h5committest and fuss.
Description: The API function H5Tis_hard() which was recently checked
in has been renamed to H5Tcompiler_conv() to be more descriptive. No
other changes.
Platforms tested: fuss - simple change.
Misc. update: config/lt_vers.am to update libtool version.
Bug fix
Description:
Building with --disable-static seems to have been broken on several platforms.
Fixed this.
Configure will now disable shared libraries automatically when using pgf90
or when building on Cygwin.
Solution:
To avoid errors when using shared libraries with pgf90 (which I had not
realized were compiler-specific), I had manually set convenience libraries
to use the -static linking flag. Apparently, this is not necessary, and
caused these libraries to be created as empty archives when --disable-static
was used.
Also, some libraries were including other libraries, which was not
necessary.
I also fixed code in configure.in to correctly detect whether shared
or static libraries are enabled, and moved code that disables shared libraries
to before libtool is created (rather than editing libtool after the fact).
Despite repeated warnings that only one shared library can be linked at a
time, I have yet to have shared libraries break the linking of tests on
any system. We'll see if the Daily Tests turn up anything.
Platforms tested:
mir (fortran, C++), sleipnir (C++), modi4 (fortran, C++, parallel),

Description: Brought back changes from SX-6.
Solution: Tests will not compile. Fixed.
Platforms tested: SX-6, heping and mir with new g95
Misc. update:
Description: Quincey added the condition branch (else if (*((ST*)S) != (ST)((DT)(*((ST*)S)))))
in the definition of the macro H5T_CONV_Fx_CORE. It handles a special situation
when the source is "float" and assigned the value of "INT_MAX". Compilers do roundup
making this value "INT_MAX+1". This branch is to check that situation and return
exception for some compilers, mainly GCC.
The branch if (*((ST*)S) > (DT)(D_MAX) || (S_PREC < D_PREC && *((ST*)S) ==
(DT)(D_MAX))) is for some compilers like Sun, HP, IBM, and SGI where under
the same situation the "int" doesn't overflow.
A test was added to dt_arith.c to check 2 conversions, from float to int where the
float is INT_MAX, and from double to signed char where the double is SCHAR_MAX.
Platforms tested: h5committest and fuss.

Description:
Merge back changes from "compact group" work that improve the

- Move datatype allocation into single internal routine, instead of
duplicated code that was spread out in a dozen or so places.
- Clean up guts of object header routines (H5O_*) to allow for some of
the fancieroperations that need to be performed on groups, along with
some general improvements.

Bug fix
Description:
Incorrectly terminated the received string in getenv_all
Solution:
Tasks would incorrectly terminat the environment string they received from the
root task in getenv_all.
They did the equivalent of:
env[strlen(str) + 1] = '\0'.
This resulted in a single "garbage" character inserted
at the end of the string. This wasn't noticed until now because it seems that on most
platforms this garbage character was a 0 anyway.
This has been corrected to;
env[strlen(str)] = '\0'.
Platforms tested:

Bug fix & code cleanup
Description:
Address most of datatype conversion exception handling bug that Ed

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.
Platforms tested:
heping, mir, modi4, sol
Misc. update:
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.

Bug fix and improvement.
Description:
The test output were not displayed for parallel tests.
The serial tests output were always displayed whether the test was
actually ran this time or not.
Solution:
Moved the display of test output inside the target where the actual
tests are run.
Platforms tested:
Tested in heping using pp and fortran.
Bug fix and code minor cleanup.
Description:
The attempt to redirect stderr together to the log files were
done in the wrong order such that stderr output goes to where
stdout WAS. Fixed that.
Code minor cleanup--use shell variables to hold the name of the
log file and the test instead of generating them repeatedly. This
makes easier code reading, less crowded and avoid typos.
Only conclude.in is changed. The Makefile.in changes are all
derived from automake.

Makefile feature
Description:
'make check-clean' now cleans *.h5 files created by tests as well as
.log and .chkexe files.
Solution:
check-clean is now a separate target in its own right, which cleans less
than mostlyclean (check-clean < mostlyclean < clean < distclean).
Platforms tested:
mir, heping, modi4 (serial and parallel)
Feature: check-clean target
Description:
'make check-clean' cleans up output files from tests.
Solution:
Tests create foo.chkexe and foo.log files. Scripts create foo.chksh and
foo.logsh files. 'make check-clean' will clean these files up so that
the tests can be re-run.
Also suppressed some not-very-useful output of Makefiles when it would
echo commands.

Configuration feature
Description:
Serial test output is now stored in log files and printed when all tests
in a directory complete, or when a test fails. This should make test output
more readable and useful.
Also made changes to clean up ii_files directories that are created by some
C++ compilers/linkers.
Also fixed a few minor Makefile bugs.
Solution:
When serial tests run, their output is saved in *.log or *.logsh. While
running, tests only print when they begin and when they complete; their
more specific output (from the log file) is printed if the test fails or
when all tests have completed.
Comments welcome.

Description: When converting floating-point numbers to integers and the values of
floating-point number are greater than the maximal value of integer, Cray X1 generates

Solution: Added a test in configure to detect Cray X1's exception. Set a flag to
indicate the machine that can handle overflow converting all floating-point to all
integer types. This flag should be set for all machines, except for Cray X1 where
floating exception is generated when the floating-point value is greater than the
maximal integer value.

Description:
When a series of files is mounted on one another and one of those files

Feature: tests now use parallel make and only run once
Description:
When make is invoked in parallel (using the -j option), several tests will
now be run simultaneously. This should speed up testing on a number of
systems.
When a test passes, it creates a foo.chkexe or foo.chksh file, which prevents
the test from running again unless the test or library changes.
Solution:
Most of the changes live in config/conclude.am. Added *.chkexe and *.chksh
files to the list of files to be cleaned at "make mostlyclean" time.
Parallel tests still run one at a time, but use the same make instructions
as serial tests.
Platforms tested:
mir, eirene, sleipnir, pommier, copper, modi4 (some errors occurred, probably
due to the test being run before updating hdf5. Will re-run tests after
checkin.)
Renamed file_handle.c as vfd.c since its tests have evloved from

Misc. update:
Interim checkin of code changes moving management of the is_dirty flag

Description:
Prior to this checkin, management of the is_dirty flag was handled
above the level of the metadata cache. This can no longer be allowed,
as it introduces a race condition in the proposed fix for a cache
coherency bug in PHDF5.
Solution:
Move management fo the is_dirty flag to the cache code proper.
Entries are now marked as dirty via a flag on the unprotect call.

Description: In this data conversion test, from floating number to floating number,
when the source is bigger than the destination, overflow may happen. The library

Solution: When this situation occurs, simply check if the destination is INFINITY
instead of comparing values.

anywhere in file. When family file is opened, the first member size determine
the member size.
Solution: this is the fifth step of checkin. Backward compatibility with v1.6
is tested. A family file created was created with the v1.6 library and opened
with this version of the library.
In the fourth step of checkin, a test suit is added for h5repart,

and a program to verify repartitioned files can be opened by the library.
There's a change from the first step of checkin. Family name template is no

Description:
Add "memory pool" internal data structure. This set of routines is
designed to add a way to allocate small pieces of information for a particular
purpose and then free all the pieces at once (i.e. without having to free each
piece individually). Memory pools are also good for localizing lots of small
allocations that logically belong together.
For example, if you were constructing a temporary linked list, you could
create a new memory pool, allocate all the nodes for the list from the memory
pool and when you were done with the list, just destroy the pool instead of
tracking through the list and freeing each block independently.

Use getenv_all for determining HDF5_PARAPREFIX instead of getenv
Description:
the environment variable HDF5_PARAPREFIX is now determined collectively, instead of

Solution:
Environment variables set for task 0 often do not propogate to other tasks which
leads to obscure and hard to track down bugs. getenv_all was written to overcome
this by having all tasks query a single task for the value of its environment.
Eventually, all calls to getenv will be migrated to use getenv_all. For now,
only HDF5_PARAPREFIX will be determined this way.

The nbit filter test case (compound datatype with no-op field)
can not pass the daily test on heping and eirene when the

Solution:
It was found that the seg fault disappears when adding a new
index variable in the test case and using it instead of using
an existing index variable twice during initialization.
This does not make much sense since previous codes is logically
equivalent to the changed codes. So, some other factors beyond

Description:
Added new function, getenv_all (only for parallel builds)
Solution:
getenv_all is a collective version of getenv. It is used to the return the value of
an environment variable in another task and can be used to synchronize all of the
environment variables used by all of the tasks. This helps to fix problems that commonly crop up
(like with HDF5_PARAPREFIX) when an environment variable does not propogate to other tasks.

detect shell automatically. This is what v1.6 does, and avoids
problems on janus.
Platforms tested:
sleipnir, copper, modi4, mir
Purpose:
Bug fix
Description:
test/big fails randomly with a message warning of 'possible overlap.'
Solution:
Have the random number generator check each value to make sure a write at
that position doesn't overlap any previous write.
Platforms tested:
sleipnir, modi4, eirene
New feature
Description:
Add first iteration of "segmented heap" code, which will be used to store
links in groups in a more flexible way than the previous "local heap" mechanism.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Solaris 2.9 (shanti)
Feature - conditional compilation
Description:
SRB file driver and tests are now compiled only when SRB is enabled
(using --with-srb during configure).
Solution:
Added an automake conditional in configure.in, altered Makefiles.am in
src and test directories to depend on that conditional.
This should make a nice example for posterity to add conditionally
compiled sources.
Platforms tested:
heping (only configure change)
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: In test_conv_flt_1() in dtypes.c, the case of Intel-Linux or
AMD-Linux "long double" wasn't considered. The precision is smaller than
the size. There may be some garbage left in the unused bytes during hardware
conversion.
Solution: Clear those bytes before comparison.
Platforms tested: h5committest and mir, modi4.
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.
Bug fix.
Description:
One test case of scaleoffset filter has fill value too large for int.
Solution:
Change the value to be within the range of int.
Platforms tested:
heping
Misc. update:
New feature.
Description:
The scaleoffset filter is now complete for compressing integers. All previous
bugs have been fixed. The filter does not compress floating-point at present.
Solution:
Update test cases for the scaleoffset filter. Two for integer types and one for
floating-point (even though the filter does not compress). The two test cases
for integer type tests situations where fill value is defined and undefined for
the dataset.
Platforms tested:
heping, copper, shanti
Misc. update:
Description:
Added function IncTestNumErrs to increment the number of errors
that is defined in testframe.c
Platforms tested:
Linux 2.4 (heping)
AIX 5.1 (copper)
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:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Description: The 4th step of change conversion test. This checkin is only for
conversion between floating-point numbers.
Solution: The source buffer of floating-point number is filled up in the same
way described in the 3rd step(revision 1.155).
Platforms tested: h5committest and fuss.
Description: This commit is actually revision 1.155, which is the 3rd step of
changing conversion test. It's for conversion from floating-point to integer.
In this step, 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.
There're also fixes in config/hpux11.00 for kelgia where default macro table
size wasn't big enough to handle the big macro in dtypes.c.
Platforms tested: h5committest and kelgia.
Bug fix
Description:
Fix a typo in my last checkin. Should make some compilers happier
about "operand types."
Platforms tested:
sleipnir, heping, kelgia
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)
New feature/tests
Description:
Add better support & tests for removing blocks being tracked.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
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:

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.

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.
Bug fix & new feature
Description:
Fix errors in tracking the total number of records "below" a node.

Description:
Fix several bugs in B-tree insertion code, which now appears to be fully
functional. (Tested to 1,280,000 records at least...)
Add random record insertion test to shake out boundary conditions, etc.
Platforms tested:
FreeBSD 4.11 (sleipnir)

Too minor to require h5committest
New feature.
Description:
Add a test case for scaleoffset filter (integer type). For debugging purpose only.
The test case is not turned on.
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
New feature & bug fix
Description:
Allow root node to split, forming a level 2 B-tree
Fix error where wrong record was being copied up to parent node for a 2
node redistribution on the "right" side of the B-tree.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Solaris 2.9 (shanti)
Bug fix
Description:
Arabica exhibited strange errors when linker found wrong versions of
header files. This happened because include directories were
given to linker in the wrong order.
Solution:
Move include directories from AM_CFLAGS variable to INCLUDES
variable to put them before CPPFLAGS variable. Trust me, it works.
This bug may also have contributed to strange errors on other platforms
(kelgia?).
Platforms tested:
copper, sleipnir, arabica.
(h5dump broke while building on arabica, but this happened in
a clean checkout, too).
Bug fix
Description:
pmake (on modi4, for instance) complains about undefined variables
if it is run without the -V flag, which turns those errors to warnings.
Solution:
Added test to configure.in to see if $MAKE will allow Makefiles
with undefined variables. If not, sets -V flag in AM_MAKEFLAGS.
Ensured that all custom make targets use AM_MAKEFLAGS.
Also defined all variables that caused errors in top-level Makefile.am.
This means that pmake can be used to build hdf5 *from the top level
only*. To run make from a subdirectory, still need to use -V flag
(or use make or gmake).
Platforms tested:
modi4, heping, copper, sleipnir
Description: For hardware conversion from integers to "long double" on AMD machine, the test
failed because the size of "long double"(can be 16 bytes) is bigger than the precision(80 bits).
There can be some garbage in the unused bytes in "long double". That caused failure during
byte comparison.
Solution: Clean these unused bytes before comparison.
Platforms tested: mir and fuss; simple change
New feature & code cleanup
Description:
Change some references from 'keys' to 'records', which is more correct for
this implementation.
Added feature to allow preemptive 3 node record redistributions (for leaves
only currently)
Added feature to perform preemptive 3->4 node splits (for leaves only
currently)
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Solaris 2.9 (shanti) w/purify
Too minor to require h5committest
New feature & bug fixes
Description:
Checkpoint v2 B-tree code after getting preemptive 2->3 node splitting
working (for leaf nodes only at the moment, however).
Also, correct a problem with redistributing records that was probably
causing the failures on mir in yesterday's daily tests.
Ran code through purify on shanti and cleared up some warnings.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Solaris 2.9 (shanti) w/purify
Description: Added support of hardware conversion between "long double" and integers(mainly
in H5Tconv.c) and some test cases(mainly in test/dtypes.c).
Platforms tested: h5committest and fuss.
Misc. update: RELEASE.txt
New feature
Description:
Checkpoint v2 B-tree code after getting 2 leaf record redistribution
working and tested.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Too minor to require h5committest
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
Bug fix & code update
Description:
Fix error in new free-list factory routines that was causing errors on
tungsten, et al.
Also, checkpoint v2 B-tree code.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Linux 2.4 (tungsten)
Otherwise too minor to require h5committest
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
Misc. update: RELEASE.txt
Bug fix (sorta)
Description:
Disable btree2 testing until Monday, when I can look into the failures
without a toddler on my lap. :-)

records are inserted and move metadata cache callbacks into their own source
file.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Too minor for h5committest
Purpose:
Bug fix
Description:
Parallel builds were breaking in tools/lib
Solution:
talign didn't realize it depended on libh5tools.la because its
dependencies listed the full path (../../tools/lib/libh5tools.la).
Changed this, and made similar changes in a couple of other
directories.
This checkin should also add the --foreign flag to every Makefile.in
Platforms tested:
sleipnir (minor change)

Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Too minor to require h5committest
Bug fix
Description:
Found the permanant fix to automake/CVS dependency problem
Solution:
Added AM_MAINTAINER_MODE macro to configure.in.
Now automake will never try to regenerate Makefiles, Makefiles.in,
configure, H5config.h, etc. when they are out of date, nor will it
print any warnings.
Developers should be very very careful to use reconfigure script,
and can add --enable-maintainer-mode flag to configure on heping
to regenerate these files correctly.
Platforms tested:
heping sleipnir copper
Bug fix
Description:
Configuration files' timestamps were incorrect.
Solution:
Update Makefiles.in. Also added correct paths to autotools on heping,
so heping build should be able to re-generate configuration files even
if they are still broken.
Platforms tested:
sleipnir
Bug fix
Description:
Dependencies between configure files (aclocal, configure.in, configure,
Makefiles.am and .in) are still causing Makefiles to try to run autotools
during build.
Solution:
Committed all Makefiles.in to update their timestamps.
As a temporary measure, forcibly prevented automake from running
autotools during build by redefining the variables it uses.
Platforms tested:
sleipnir (No changes to Makefile content)
Description: To avoid randomly generating NaN for "long double" during
conversion test, decrease the exponent by 1 if all exponent bits are set
1s.
Platforms tested: eirene(production) and fuss.

Description:
Different compilers use different flags to include Fortran module files
Solution:
Changed boilerplate to use configure variable rather than hardcoded -M flag.
Platforms tested:
sleipnir, sol, copper
Configuration feature
Description:
HDF5 now uses automake to generate Makefiles
Solution:
Makefile.in files are now generated from Makefile.am files.
To reconfigure (after chaning a Makefile.am or configure.in):
/bin/sh bin/reconfigure.sh
Platforms tested:
Many
Description:
For Intel machines, the size of "long double" is 12 byte, precision
is 80 bits, mantissa size is 64 bits, and no normalization. So the
most significant bit of mantissa is always 1 unless the floating number
has special value. This step tries to compensate this case by turning
on the most significant bit of mantissa if the mantissa bits aren't
all 0s.
Solution:
Tries to compensate this case by turning on the most significant bit of
mantissa if the mantissa bits aren't all 0s.
Platforms tested: eirene and fuss(production enabled). Small change for
production only.
Add test cases of nbit filter, tests are now turned on
Description:
Six test cases are added for testing the nbit filter with different
datatypes including int, float, double, array datatype, a simple
compound datatype and a complex compound datatype. Improvements are
made to testing of int and floating point.
Solution:
Platforms tested:
AIX 5.1 and Linux 2.4.
Misc. update:
Reduce the run time of the cache tests.
Description:
Some of the cache tests run for quite a while, which has been
causing problems with our daily build and test. In my last
modification to cache.c, I added code to skip these stress
tests unless we were building in production mode. Since
things go faster in production mode, the extra tests are not
a major problem here.
However, this means that the stress tests are only run once
or twice a week.
Solution:
To try to deal with this, I modified the four longest tests
to throttle depending on whether NDEBUG is defined. When
NDEBUG is not defined, runtime for the cache tests should
be about 1/5th its regular run time. We will see if this
is enough of a reduction to avoid problems.
There is some doubt in my mind as to just how much good the
throttled tests do, but they should be better than nothing.
As mentioned before, the correct solution is to build some
proper, random test code.
Platforms tested:
h5committested
production and debug builds on heping.
Misc. update:
Adding N-bit testing source code into CVS tree.
This is for debugging purpose only. N-bit filter won't be included in the daily test.
Description:
Integer, Float, Array datatype and Compound datatype tests are included.
More comprehensive tests need to be done.
Solution:
Platforms tested:
copper(AIX 5.1) and heping(Linux 2.4).
Misc. update:
1) Provide facilities in cache to allow us to avoid a potential cache
consistency bug in the parallel case.
2) Clean up a off by one sanity checking bug.
3) Turn off execution of long running tests in debug mode.
Description:
1) In the parallel case, all writes to metadata must be collective,
but reads may not be. In pricipal, this allows us to different
contents in different caches. This isn't a problem as long as the
correct data is always on disk, but unless we can force certain
writes immediately, that need not be the case.
2) & 3) should need no further explanation.
Solution:
1) Add code allowing us to mark cache entries, and then force
these entries to be flushed at a later time.
Note that to actually avoid the bug, we will have to modify
existing code to use these new features.
2) & 3) should need no further explanation.
Platforms tested:
heping (serial debug and production)
committest (copper, sol, and heping). test failed on heping in the
c++ portion of the build, but at Quincey's siggestion, I am proceeding
with the checkin.
Misc. update:
Description: Test conversion from native integer to derived floating-point type and convert back;
test conversion from derived floating-point to derived floating-point types and convert back. Fixed
a few minor bugs related to type conversion in the library.
Platforms tested: h5committest and fuss
Description: The functions for user-define floating-point type, like
H5Tset_fields, H5Tset_offset, H5Tset_precision, H5Tset_size, have some
minor bugs. For error checking, the library didn't include offset value
somehow.
Solution: Corrected those bugs.
Platforms tested: h5committest and fuss
Misc. update:
Description: There was a #ifdef statement with logical AND in it.
Solution: Change it to #if statement.

Description:
Fix possible overrun in error description string by allocating large enough
string on the fly.
Platforms tested:
FreeBSD 4.10 (sleipnir)
Too minor to require h5committest
Description: The fix of the loss problem of the last 2 bytes of mantissa on sleipnir has
not been successful. It happens when converting from unsigned long long to long double.
The failure has been on and off.
Solution: Hard set a macro to disable unsigned long long->long double for FreeBSD until
a good solution is found to solve this elusive problem.
Platforms tested: sleipnir and fuss. Only sleipnir is concerned.
Misc. update:
Description: the last 2 bytes of mantissa can be lost when converting from unsigned long long
to long double. In last check-in, a fix was made to ignore that precision loss. But sometimes,
the last 2 bytes are rounded up to the 3rd last byte.
Solution: Ignore the 3rd last byte, too, when comparing values.
Platforms tested: sleipnir - only this system is concerned.
Description: For FreeBSD (sleipnir), when GNU compilers do conversion from
unsigned long long to long double, the last 2 bytes of mantissa are lost.
The impact of precision loss isn't significant.
Solution: Detect this case on FreeBSD in configure, ignore it in dtypes.c
test instead of return failure.
Platforms tested: sleipnir, fuss, modi4. These systems are mainly concerned.
Reduce run time of daily tests.
Description:
cache, the test program for the metadata cache has been taking a while
to execute.
Solution:
As a short term "fix", I have commented out all but one of the long
running test functions. Of course that means that we aren't running
these tests at present. I'm not sure that this is a good idea.
Platforms tested:
Serial on Heping.
Misc. update:
Description: For HP-UX 11.00, the compiler generates 'floating exception'
when converting 'long double' to most of integer types.
Solution: Define a macro for all other systems except HP-UX 11.00. Hard set
this macro to 'no' in config/hpux11.00 to skip this test for HP-UX 11.00.

Description: Windows .NET 2003 can't handle float(double)->long_long hardware conversion.
While the problem hasn't been determined, we temporarily disable that test by using a
condition macro. Let Windows define that macro. Other systems don't have it defined.
Platforms tested: mir and eirene.
Description: integer->long double conversion test failed on some of Linux
systems(mir and eirene) when Intel compiler is used. I'm not able to repeat
the problem. So I just made a best guess and fix it. The problem is minor.
The long double on Linux is 12 bytes long but precision is 10 bytes. The
unused 2 bytes may have garbage in them causing value comparison wrong.
Platforms tested: mir and eirene with Intel compiler.
Description: 2 small things to correct:
1. the change in H5config.h.in was wept out by a later change.
2. long long isn't supported on Windows. It's long_long instead.
Platforms tested: fuss(linux 2.4)
New feature

Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".

Misc. update:
Modify the cache code (H5C) to support automatic cache resizing to
adapt to the work load at run time.
Description:
Different applications require different sized caches to maintain
an acceptable hit rate. This set of changes attempts to provide the
ability to adjust to circumstances automatically.
Solution:
Added highly configurable code to allow the user to either set a
fixed cache size, or allow the cache to grow and shrink according to
conditions.
If enabled, cache size increases are triggered when the hit rate
drops below a user specified threshold in a user specified interval.
Cache size reductions (if enabled) are triggered when either the
hit rate exceeds some user specified threshold over a user specified
interval, when the cache contains "enough" entries that haven't been
accessed for a user specified interval, or some mix of the above.
See the header comments on the H5C_auto_size_ctl_t structure in
H5Cprivate.h for further details.
At present, the cache resize configuration options are not
accessible via the user API. Must add this.

Add new internal data structure
Description:
Add an implementation of skip lists to the library (see comment in
src/H5SL.c for references to the papers describing them) as a potential
replacement for our current threaded, balanced binary tree container.
Skip lists are much simpler to implement and should be faster to use.
Also, added new error codes to release branch, so bump the minor version
number to indicate that the library is no longer perfectly compatible with
the 1.6.3 release.

Too minor to require h5committest
Purpose: Correction to previous bug fix. This checkin is mainly to let user
test his program.
Description: For family driver bug(#213), the previous fix was imperfect. The problem
was when user create family file, the member size information wasn't saved in file. When
the file was re-opened, the library simply use the size of 1st member file as member size.
Solution:
When file is re-opened, member size passed in from access property
is checked to see if it's reasonable. If there is only 1 member
file, member size can't be smaller than current member size.
If there are at least 2 member files, member size can only be equal
to the 1st member size.
Platforms tested: h5committest and fuss
Description: H5Pset_fapl_family sets family member size only for creating
new file. The file doesn't keep this size information. When the file is
re-opened, the size of first member file is used as the member size.
Solution: Assume user knows the original member size and sets it through
H5Pset_fapl_family. That will be the member size. User can pass in value 0
as member size if he doesn't know the original member size. Library will
choose the size of current first member size as the member file size.
Platforms tested: h5committest and fuss.
Bug fix, sorta.
Description:

Long double is a standard C89 type. Promoted it from
a conditional tested type to an assumed supported type.
Platforms tested:

Misc. update:
Description: "char" was considered as always "signed char" in data type conversion. However, ISO C leaves
the definition of "char" to individual implementation. i.e. for IBM AIX C compiler, it's treated as "unsigned
char".
Solution: Changed all "char" to "signed char". Don't even do "char" anymore because its definition is up
to each vendor.
Platforms tested: h5committest
Add code more code to test H5Pget_data_transform and H5Pset_data_transform

Misc. update:
tconfig.c:
Verified only the unsigned int types and did not detect inconsistencies
on signed type such as int_fast16_t.
Changed code to verify both signed and unsigned int types wherever
applicable. It also depends on signed and unsigned forms of an

Purpose: change feature
Description: Back up support bitfield and time datatypes in H5Tget_native_type.Leave it to future support. Let it return "not supported" error message for

Platforms tested: h5committest and fuss.
Misc. update: RELEASE.txt
Purpose:
Feature
Description:
Datatypes and groups now use H5FO "file object" code that was previously
only used by datasets. These objects will hold a file open if the file
is closed but they have not yet been closed. If these objects are unlinked
then relinked, they will not be destroyed. If they are opened twice (even
by two different names), both IDs will "see" changes made to the object
using the other ID.
When an object is opened using two different names (e.g., if a dataset was
opened under one name, then mounted and opened under its new name), calling
H5Iget_name() on a given hid_t will return the name used to open that hid_t,
not the current name of the object (this is a feature, and a change from the
previous behavior of datasets).
Solution:
Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's,
and H5G_t's into a "shared" struct and a private struct. The shared structs
(H5D_shared_t, etc.) hold the object's information and are used by all IDs
that point to a given object in the file. The private structs are pointed
to by the hid_t and contain the object's group entry information (including its
name) and a pointer to the shared struct for that object.
This changed the naming of structs throughout the library (e.g., datatype->size
is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

Platforms tested:

Misc. update:
Code cleanup
Description:
Tweak recent "forward compatibility" changes to the H5E* API (which allowed
for the old H5E API functions to remain unchanged) by allowing for the error
stack callback function (H5E_auto_t) to also remain unchanged from the 1.6
branch. This required changing the H5E{get|set}_auto routines to have the
old style H5E_auto_t type (which didn't have a stack ID parameter) and the new
H5E{get|set}_auto_stack routines to have a newer "H5E_auto_stack_t" type (which
has a stack ID parameter). This should make the H5E API changes as forwardly
compatible as possible.
One side-affect of this change was that it was impossible to determine if
the current auto error callback was the old style (H5E_auto_t) or the new style
(H5E_auto_stack_t) of callback, so a new API function (H5Eauto_is_stack) was
adde to query this.
Platforms tested:
FreeBSD 4.10 (sleipnir)

Description: One place was left out for update after the Error API was modified.

new test for the native types test
Description:
on the Cray SV1 an INT type was wrongly converted to a SHORT type
by the get_native_integer function
Choose the type based on the precision; this is to support cases
like the Cray SV1, where the size of short is 8 but precision is 32
(e.g an INT (size 8, prec 64) would be converted to a SHORT

Updated testhdf5.c to use the new syntax of TestParseCmdLine().
Platforms tested:
On eirene both serial and parallel.
Description: The test tried to read a dataset of H5T_STD_I32LE type and verify with the size
of H5T_NATIVE_INT in function test_misc20(). This will fail on some machines like Crays where the
size of H5T_NATIVE_INT is 8 bytes.
Solution: Changed from H5T_NATIVE_INT to H5T_STD_I32LE.
Platforms tested: Crays - very simple change.
Bug fix
Description:
Correct possible core dump when a datatype conversion function is
registered with the library after a compound datatype has been converted
(having it's type conversion information cached by the library). The compound
datatype must have been created by inserting the fields in non-increasing

Re-sort the fields in the compound datatypes before recalculating the
cached information when performing the conversion on them.

Bug fix.
Description:
Address two problems:
- The computation of the scanline in the szip filter was being
performed in the "can apply" callback routine instead of the
"set local" routine.
- The routine which allocated all the chunks for an entire dataset
(which is invoked when the allocation time is early or late,
rather than incremental) wasn't recording a failed filter in
the information for the chunk, causing the library to believe
that the chunk had the filter applied when it really hadn't.
Solution:
- Move the scanline computation to the "set local" callback.
- Record the filter mask with each chunk created when allocating them.
