Description: The error test script compares the error messages to the standard
output. The file names and line numbers in the messages can be different
for users.
Solution: Temporarily disable the test until find a good solution.
Platforms tested: None. Disabling a test.
Bug fix
Description:
When datasets are deleted from a file, they are removed from the sieve
buffer, but instead of invalidating only the part of the sieve buffer affected,
the sieve buffer code would throw away the entire sieve buffer, potentially
including other raw data in the buffer that hadn't been written to disk yet.
Solution:
Improve the sieve buffer clearing code to handle partial invalidations.
Platforms tested:
FreeBSD 4.8 (sleipnir)
h5committest
Bug fix
Description:
Allow a user block to be "inserted" in front of a file (probably by
writing a validly-sized userblock to a new file and then appending another
HDF5 file to the new file).
Platforms tested:
FreeBSD 4.8 (sleipnir)
h5committested
New test
Description:
Added test to check for dangling objects being handled correctly by the
library.
Platforms tested:
FreeBSD 4.8 (sleipnir)
h5committested
New test feature
Description:
Added the VFD_LIST definition to support the "make check-vfd" tests.
Platforms tested:
h5committested.
Since check-vfd is not invoked by default, I went to each machine
to invoke them by hand. The target worked fine but there were
errors reported from those driver tests. (Those errors were beyond
the scope of this make target test.)
Misc. update:
New internal feature
Description:
Add internal API for building and working with heaps (H5HP). This will be
used for the LRU algorithm in the new metadata cache code.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir)
Bug Fix
Description:
When calling H5Fopen with the core VFL driver, but without the
H5F_ACC_CREAT flag goes ahead and creates a memory file.
Solution:
Check for the H5F_ACC_CREAT flag before allowing the memory file to be
created.
Platforms tested:
FreeBSD 4.7 (sleipnir)
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.

be having problems with compressed, chunked datasets, so write some tests
to verify that its working correctly.
Also, fix case for allocating storage early for chunked datasets
Platforms tested:
FreeBSD 4.6 (sleipnir) serial & parallel
Bug Fix
Description:
H5Dcreate and H5Tcommit allow "empty" compound and enumerated types (i.e.
ones with no members) to be stored in the file, but this causes an assertion
failure and is somewhat vapid.
Solution:
Check the datatype "makes sense" before using it for H5Dcreate and
H5Tcommit.
Platforms tested:
FreeBSD 4.5 (sleipnir)
Test Bug Fix
Description:
Under certain [obscure] circumstances, an object header would get paged out
of the metadata cache, and when it was accessed again and brought back into
the cache, and immediately had additional metadata added to it (an
attribute, usually, or perhaps adding an object to a group), and needed to
be extended with a continuation message, but there was no room in any
existing object header chunks for the continuation message and an existing
object header message needed to be moved to the new object header chunk (I
told you it was obscure :-), the object header message moved to the new
chunk (not the new metadata being added) would get corrupted. *whew* :-)
Solution:
Actually copy the "raw" object header message information of the object
header message being moved to the new chunk, instead of relying on the
"native" object header message information being re-encoded when the object
header is flushed. This is because when an object header is paged out of
the metadata cache and subsequently brought back in, the "native"
information pointer in memory is reset to NULL and only the "raw"
information exists.
[Actually, this additional testing doesn't trigger the bug, which needs
_lots_ of objects to be created and accessed, but it does execise the
object header continuation code more than other tests in the library.]
Platforms tested:
Solaris 2.7 (arabica) & FreeBSD 4.5 (sleipnir)
Bug fix
Description:
$(LT_RUN) was used to execute ./H5detect in src/Makefile.in.
$RUNTEST was set to $(LT_RUN) which was used to execute sequential
executable. $(LT_RUN) is "../libtool --mode=execute". But libtool
invokes some commands that are not supported in the Tflops machine.
That caused failures during the build and check processes.
Solution:
Upon investigation, there does not seem to be need to use $(LT_RUN)
any more. The "libtool --mode=link" now generates a "fake" executable
that is actually a command-script file that can regenerate the real
executable with dynamic libraries hooks setup properly.
Undo all those $LT_RUN substitute and let $RUNSERIAL execute those
sequential executables.
Platforms tested:
Eirene(serial), modi4(parallel)
Bug fix
Description:
When several level deep nested compound & VL datatypes are used, the data
in the nested compound datatypes is incorrectly sharing the same "background
buffer", causing data corruption when the data is written to the file.
Solution:
Allocate a separate background buffer for each level of the nested types
to convert. (Also allocate temporary background buffers for array
datatypes, where this sort of problem could occur also)
Added more regression tests to check for these errors.
Platforms tested:
FreeBSD 4.5 (sleipnir) & Solaris 2.6 (baldric)
Bug Fix
Description:
Regression test for following bug:
The H5Gget_objinfo() function was not setting the 'fileno' field in the
H5G_stat_t struct passed in.
Solution:
Added a "file serial number" to each file currently open in the library
and put that in the 'fileno' field. If a file is opened twice (with
H5Fopen) and the VFL driver detects that it is the same file (i.e. the
two file structures have the same "shared file info" in the library's
memory structures), they will have the same serial number.
This serial number has two drawbacks:
- If a VFL driver doesn't/can't detect that two calls to H5Fopen with
the same file actually _are_ the same file, each will get a
different serial number
- If the same file is closed and re-opened, the serial number will be
different.
It is be possible to fix the second drawback for many VFL drivers, but it
would be a lot of effort and probably isn't worth it until we've got a
good reason to do it. Dunno if we'll ever be able to fix the first
drawback...
Platforms tested:
FreeBSD 4.5 (sleipnir)
VS: ----------------------------------------------------------------------
Cleanup
Description:
Added set_extend.h5 file to the CLEANUP macro in the Makefile so that
it'll be removed when the other temp files are removed.
Platforms tested:
Linux
Bug Fix
Description:
When file space was returned to the file space free-list for reuse,
occasionally raw data allocations which used space from the free-list
would overlap with the metadata accumulator and get over-written with
the cached information in the accumulator, corrupting the data.
Solution:
Check if the space about to be recycled on the free-list is going to be
used for raw data and also overlaps with the metadata accumulator cache,
avoiding using space that fits those criteria.
This fixes bug #701
Platforms tested:
FreeBSD 4.5 (sleipnir)
Removing the DPSS (gridstorage) driver source code.
Description:
The DPSS (using Grid-Storage) driver is retired.
Removed the configure option with-gridstorage from configure.in.
Cvs remove the following files
./src/H5FDdpss.c
./src/H5FDdpss.h
./test/dpss_read.c
./test/dpss_write.c
Regenerated Dependencies files (some had to be hand-edited since
'make depend' did not cover them.)
Removed reference to DPSS Virtual file driver from H5F.c.
Platforms tested:
modi4 (Parallel; -with-gass=...), eirene, arabica (fortran, cxx).
New feature.
Description:
Added a test to verify the correctness of information provided by
configure in H5config.h. Some information, such as SIZEOF some
types can be hardcoded by config/<machine>. This test verified
the information is indeed correct.
Currenly, only size of C language types are verified.
Platforms tested:
Eirene, regular, arabica.
New Feature
Description:
Added array datatype tests to the regression tests. These datatype
combinations are tested currently:
1-D array of atomic datatypes
3-D array of atomic datatypes
array of array of atomic datatypes
array of compound of atomic datatypes
array of compound of array datatypes
array of VL of atomic datatypes
array of VL of array datatypes
Also added a test to verify that the older style compound datatype with
array fields works correctly.
Platforms tested:
FreeBSD 4.1.1 (hawkwind)
Bug fix
Description:
"Time" datatypes (H5T_UNIX_D*) were not being stored and retrieved in
the datatype object header message correctly.
Solution:
Store endian-ness and precision in the datatype object header message and
added test to continue to track them working correctly.
This fixes bug #512.
Platforms tested:
FreeBSD 4.1.1 (hawkwind)
zlib, and zlib isn't in our LD_LIBRARY_PATH or in a standard system
library place (/usr/lib or /lib), then the tests can't run. This fixes it
if the person configures the source with the flag:
--with-zlib=/usr/fnord/include,/usr/fnord/lib
This only works if you're pointing to the shared library version in the
above flag...
that all HDF5 API functions are protected by a mutex lock. Basically,
serialized all API calls. To use it, use
configure --enable-threadsafe --with-pthread
