Bug fix
Description:
A few groups were left open after they were used.
Solution:
Closed them. :-)
Platforms tested:
FreeBSD 4.8 (sleipnir)
h5committested
Bug Fix
Description:
Some compilers aren't happy if you specify the same library multiple
times when linking. This caused HDF5 Lite to crash during tests on
Kelgia
Solution:
Modified the script so that the shared libraries are specified only
once for the commandline.
Platforms tested:
Kelgia (small fix).
Misc. update:
Bug Fix
Description:
When doing a "configure" using the h5cc script as the compiler, it
would fail to accept the "-E" flag as running the preprocessor. The
problem was that it was trying to link the file afterwards. Of
course, the file wouldn't be there, so it would fail.
Solution:
Changed it so that if the -E flag is used, then we don't try to link
(this is how it's done in mpicc...I must have copied it wrongly).
Platforms tested:
Linux & Kelgia (small change not needing full testing)
Misc. update:
changed algorythm
Description:
changed the array_diff function to increment the read buffer with a size selected
by an appropriate native data type.
previously it was assumed, e.g. int size = 4 bytes
Solution:
Platforms tested:
Linux 2.4 (rockaway)
SunOS 5.7 (arabica, 64bit mode)
IRIX 6.5 (modi4)
Misc. update:
Bug fix
Description:
The tests would just segmentation fault in Tflops because the
compiled code were launched without using the $RUNSERIAL to launch
them. This may fail in some batch systems like Tflops.
Solution:
Used $RUNSERIAL to launch the compiled code.
Also fixed a typo of the script command line.
Platforms tested:
Only tested in Tflops since the modified code resided there.
Misc. update:
bug fix
Description:
datasets with different storage datatypes where not read to memory to same size types
Solution:
obtain the memory type and size, for the TWO datasets ,
with the "fixtype" function
"upgrade" the smaller size to the larger if they are different
added H5DIFF_DEBUG flag for print information
Platforms tested:
Linux 2.4 (rockaway)
SunOS 5.7 (arabica, 64bit mode)
IRIX 6.5 (modi4)
Misc. update:
added new test files for h5diff
bug fix
Description:
the criteria for determining the correct switch case cast to void* to type* was the data size read from disk.
this was causing problems on Cray T3E, where all integer except char are 8 bytes long
Solution:
changed the criteria for using the memory size instead, which is determined by the same function
that reads the data into memory
the messages " using memory NATIVE_TYPE_X" were removed, because they might not coincid on different
platforms.
Platforms tested:
Linux 2.4 (rockaway)
SunOS 5.7 (arabica)
IRIX 6.5 (modi4)
Misc. update:
New feature/enhancement
Description:
Chunked datasets are handled poorly in several circumstances involving
certain selections and chunks that are too large for the chunk cache and/or
chunks with filters, causing the chunk to be read from disk multiple times.
Solution:
Rearrange raw data I/O infrastructure to handle chunked datasets in a much
more friendly way by creating a selection in memory and on disk for each chunk
in a chunked dataset and performing all of the I/O on that chunk at one time.
There are still some scalability (the current code attempts to
create a selection for all the chunks in the dataset, instead of just the
chunks that are accessed, requiring portions of the istore.c and fillval.c
tests to be commented out) and performance issues, but checking this in will
allow the changes to be tested by a much wider audience while I address the
remaining issues.
Platforms tested:
h5committested, FreeBSD 4.8 (sleipnir) serial & parallel, Linux 2.4 (eirene)

Misc. update:
Feature Add
Description:
It's now possible to print out characters as actual characters
instead of their decimal equivalent numbers. It's the same thing that
h5ls does. The flag to do this is "--string" or "-r".
Platforms tested:
Verbena (Fortran & C++)
Arabica (Fortran)
Modi4 (Fortran & Parallel)
Misc. update:
Bug fix
Description:
"$@" was used to represent all argument provided. This has the
unfortunate effect as one argument of "" when actually no argument
was given. Some machines throw the "" away but some like Tflops
and Alpha Q, retains them as a single argument of "". This caused
the no filename given test to fail.
Solution:
Replaced "$@" with a plain $@.
Platforms tested:
h5committested
Misc. update:
added more tests, described in the test matrix
Description:
test -r
test -l
expanded -d, -p and -n tests
test different types to include links and named types
test for non supported classes, e.g bitfield, opaque , etc
Platforms tested:
Linux 2.4 (rockaway)

Misc. update:
update
Description:
Added h5fc to the h5tools list.
Added feature that it will udpate tools that are present.
(Would still abort if no tools found at all.)
Platforms tested:
Did not h5committest since it does not test this tool at all.
Did various test in eirene by hand.
Misc. update:
added some niceties and utilities, and more tests
Description:
some niceties: more error messages on cases of bad input
utilities: some functions to more human readable output
more tests: described in the test matrix
Platforms tested:
Linux/rockaway(C)
SunOS/arabica (C)
SGI/modi4 (C)
Purpose: Bug fix
Description: On HP11.00 and True64 systems strtoll function that is used
to read text to long integers is not available. Compilation
fails for h5import.c
Solution: Replace strtoll with HDstrtoll. HDstrtoll is a private HDF5 function
defined in H5private.h file, but this include file was already used
by h5import for some other reasons. It would be probably better
to choose strtol or strtoll functions at the configuration
time, but HDstrtoll provided really simple solution for now.
Platforms tested: arabica (to test that where it was working, it is still working),
kelgia (HP11.00) and PSC True64 machine.
Misc. update:
Purpose: Bug fix
Description: h5import tests will fail if srcdir option
is used with configure.
Solution: Modified h5importtest.c h5importtestutil.sh files
to search for input files in the proper directory and
to write output files to the proper directory.
Platforms tested: Tested on burrwhite, arabica, and modi4.
Unfortunately srcdir option was used only on
arabica, since I am having a weird 'timezone'
problem on all Linux machines when srcdir is used, and
on modi4 build has to be done in the same directory (at
least this is a message I am getting from configure;
should it work?)
Misc. update:
added more tests to automatic testing
Description:
added test for an invalid option letter
added test for -h option
added test for an invalid option -d
added test for an invalid option -d number
Solution:
Platforms tested:
linux, solaris, sgi
Misc. update:
Purpose: Maintenance
Description: There was an old h5import (h5import.c) tool in the misc directory.
The tool created 8-bit integer datasets , it was never tested and/or
supported.
Solution: We decided to rename old h5import.c to h5createU8.c. The new name reflects what
actually old tool does. New executable h5createU8 is built in the misc directory.
h5import.c file (old one) is still in the misc directory, but h5import executable
is not built. (Sorry if I confused you!)
Platforms tested: vebena, arabica, modi4 were tested
Misc. update:
Purpose: New tool
Description: Pankaj created h5import tool long time ago. I am finally checking
the source code in for the 1.6 release.
Known problems: h5import test will crash if srcdir option
is used; will be fixed before the release.
Solution:
Platforms tested: vebena, arabica, modi4 were tested. h5import tests passed
I also tested on arabica with srcdir option to make sure that
there is a problem when srcdir is used. After that I disabled
h5import tests. Daily tests will build h5import, but will not run
h5import tests.
Misc. update:
added test script for h5diff
code cleaning for alpha release
makefile now generates the h5difftst.c program that generates 2 .h5 files for testing
Description:
the .sh script runs several runs of h5diff and compares the output
with a predifined output located in /tools/testfiles (.txt files)
righ now it has only one test
Solution:
Platforms tested:
linux (other platforms later , ok !? )

Bug Fix (Bug #806)
Description:
When compiling/installing with the command "make install" (without
performing a "make" beforehand) the tools weren't being made. This
was because the `install' command in the Makefiles only relied upon
public libraries, not private ones (which the one in the tools
directory is).
Solution:
Had the `install' command be dependent upon an "AUX_LIB" macro which
includes libraries which are needed but aren't distributed (that is,
they're staticly compiled).
Platforms tested:
Linux
Bug Fix
Description:
Metadata cache in parallel I/O can cause hangs in applications which
perform independent I/O on chunked datasets, because the metadata cache
can attempt to flush out dirty metadata from only a single process, instead
of collectively from all processes.
Solution:
Pass a dataset transfer property list down from every API function which
could possibly trigger metadata I/O.
Then, split the metadata cache into two sets of entries to allow dirty
metadata to be set aside when a hash table collision occurs during
independent I/O.

Lots of performance improvements & a couple new internal API interfaces.
Description:
Performance Improvements:
- Cached file offset & length sizes in shared file struct, to avoid
constantly looking them up in the FCPL.
- Generic property improvements:
- Added "revision" number to generic property classes to speed
up comparisons.
- Changed method of storing properties from using a hash-table
to the TBBT routines in the library.
- Share the propery names between classes and the lists derived
from them.
- Removed redundant 'def_value' buffer from each property.
- Switching code to use a "copy on write" strategy for
properties in each list, where the properties in each list
are shared with the properties in the class, until a
property's value is changed in a list.
- Fixed error in layout code which was allocating too many buffers.
- Redefined public macros of the form (H5open()/H5check, <variable>)
internally to only be (<variable>), avoiding innumerable useless
calls to H5open() and H5check_version().
- Reuse already zeroed buffers in H5F_contig_fill instead of
constantly re-zeroing them.
- Don't write fill values if writing entire dataset.
- Use gettimeofday() system call instead of time() system when
checking the modification time of a dataset.
- Added reference counted string API and use it for tracking the
names of objects opening in a file (for the ID->name code).
- Removed redundant H5P_get() calls in B-tree routines.
- Redefine H5T datatype macros internally to the library, to avoid
calling H5check redundantly.
- Keep dataspace information for dataset locally instead of reading
from disk each time. Added new module to track open objects
in a file, to allow this (which will be useful eventually for
some FPH5 metadata caching issues).
- Remove H5AC_find macro which was inlining metadata cache lookups,
and call function instead.
- Remove redundant memset() calls from H5G_namei() routine.
- Remove redundant checking of object type when locating objects
in metadata cache and rely on the address only.
- Create default dataset object to use when default dataset creation
property list is used to create datasets, bypassing querying
for all the property list values.
- Use default I/O vector size when performing raw data with the
default dataset transfer property list, instead of querying for
I/O vector size.
- Remove H5P_DEFAULT internally to the library, replacing it with
more specific default property list based on the type of
property list needed.
- Remove redundant memset() calls in object header message (H5O*)
routines.
- Remove redunant memset() calls in data I/O routines.
- Split free-list allocation routines into malloc() and calloc()-
like routines, instead of one combined routine.
- Remove lots of indirection in H5O*() routines.
- Simplify metadata cache entry comparison routine (used when
flushing entire cache out).
- Only enable metadata cache statistics when H5AC_DEBUG is turned
on, instead of always tracking them.
- Simplify address comparison macro (H5F_addr_eq).
- Remove redundant metadata cache entry protections during dataset
creation by protecting the object header once and making all
the modifications necessary for the dataset creation before
unprotecting it.
- Reduce # of "number of element in extent" computations performed
by computing and storing the value during dataspace creation.
- Simplify checking for group location's file information, when file
has not been involving in file-mounting operations.
- Use binary encoding for modification time, instead of ASCII.
- Hoist H5HL_peek calls (to get information in a local heap)
out of loops in many group routine.
- Use static variable for iterators of selections, instead of
dynamically allocation them each time.
- Lookup & insert new entries in one step, avoiding traversing
group's B-tree twice.
- Fixed memory leak in H5Gget_objname_idx() routine (tangential to
performance improvements, but fixed along the way).
- Use free-list for reference counted strings.
- Don't bother copying object names into cached group entries,
since they are re-created when an object is opened.
The benchmark I used to measure these results created several thousand
small (2K) datasets in a file and wrote out the data for them. This is
Elena's "regular.c" benchmark.
These changes resulted in approximately ~4.3x speedup of the
development branch when compared to the previous code in the
development branch and ~1.4x speedup compared to the release
branch.
Additionally, these changes reduce the total memory used (code and
data) by the development branch by ~800KB, bringing the development
branch back into the same ballpark as the release branch.
I'll send out a more detailed description of the benchmark results
as a followup note.
New internal API routines:
Added "reference counted strings" API for tracking strings that get
used by multiple owners without duplicating the strings.
Added "ternary search tree" API for text->object mappings.

is displayed as part of the object name, otherwise the
file name is not displayed.
Renamed h5dumptst.c to h5dumpgentest.c.
Added a test to run h5dumpgentest to make it can run without error. Note
that this does not verify if it is generating the correct test files.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}? YES
Misc. update:
Update MANIFEST if you add or remove any file. YES
Changed the file name nofilename.ddl to tnofilename.ddl, to be consistent
with the other file names.
Platforms tested:
eirene only since this is a very simple change.
Improvement
Description:
Moved the code parsing for missing file name in the parse_command_line
routine.
Added a test checking if the tool fails as expected when no file name is
given.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}? YES
Misc. update:
Update MANIFEST if you add or remove any file. YES, added nofilename.ddl
Bug fix (ID 765 and part of ID 841)
Description:
"h5dump -H" would core dump. It was because the code was not
checking if there was any file argument after option parsing.
It referred to an non-existing filename argument.
There was also some very old but not commented code which allowed
the use of back slash to escape a filename begun with '-'. The
'--' option is better and more common practice.
Solution:
Added code to check if there is still a filename argument after parsing.
(This checking probably should goto inside the option_parsing routine.
Also removed that old code mentioned above.
Platforms tested:
eirene, arabica and modi4
updated copyright note.
Copied the UNUSED correction from v1.4.
Added an example to the usage of -- option.
Description:
[describe the bug, or describe the new feature, etc]
Solution:
[details about the changes, algorithm, etc...]
[Please as detail as you can since your own explanation is
better than others guessing it from the code.]
Platforms tested:
arabica (fortran), modi4 (pp, fortran),eirene (fortran, CC).
