Regression test for bug fix
Description:
Adjust selection so chunked data needs to be read from pre-allocated chunks
w/filters, to verify that filter is applied correctly.
Platforms tested:
FreeBSD 4.6 (sleipnir) w/parallel
Purpose:
Design for compact dataset
Description:
Compact dataset is stored in the header message for dataset layout.
Platforms tested:
arabica, eirene.
Additional regression tests & bug fixes
Description:
There was no testing for the H5Dget_storage_size function and it seemed to
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
Code cleanup
Description:
Clean up a few warnings which were showing up with --enable-production
turned on.
Platforms tested:
FreeBSD 4.6 (sleipnir) serial & parallel
Update, Bug Fix, and Feature Add
Description:
- Updated how AC_{ENABLE,WITH} help messages were being generated.
Autoconf now gives you an AC_HELP_STRING macro to use to create
them.
- Fixed the problem with Linux LFS on RedHat 7.3 machines. It wasn't
finding getdents64(), so we can't rely on that being present
anymore...
- Added GPFS detection and setting.
- Updated how compression is specified. It's no longer necessary to
test for HAVE_ZLIB_H, HAVE_LIBZ, and HAVE_COMPRESS2. The one macro
{H5_}HAVE_COMPRESSION takes care of all of these.
Solution:
Changed the check for Linux LFS from looking for getdents() to
looking at the version number of the kernel (using the uname -r
command). You can still override with the --enable-linux-lfs switch
if you really believe that your <2.4 kernel has LFS support.
Platforms tested:
Linux (2.2 and 2.4)
Purpose:
New Test VL memory leak.
Description:
Test to see if VL type memory leaks when data is overwritten.
Platforms tested:
Linux 2.2(eirene), IRIX 6.5(paz).
Purpose:
Bug fix.
Description:
This test fails on TRUE64 system because a compound variable(fill_ctype
in test_rdwr) wasn't initialized.
Solution:
Initialize to zero.
Platforms tested:
Pittsburg's True64(lemieux) system.
Bug fix
Description:
I/O on "Regular" hyperslab selections could fail to transfer correctly
if the number of elements in the selection's row did now fit "evenly"
into the buffer being used for the transfer.
Solution:
Correct the calculation of the block & count offsets within the optimized
"regular" hyperslab routines.
Platforms tested:
FreeBSD 4.5 (sleipnir)
Code cleanup
Description:
The test for inserting a compound datatype into itself (which should fail)
is issuing warnings about this failure.
Solution:
Turn the warnings off during this test.
Platforms tested:
FreeBSD 4.5 (sleipnir)
Purpose:
Bug #774 fix
Description:
Added a test for the H5Tenum_nameof and H5Tenum_valueof functions.
Values that do not exists in the enumeration type are supplied to
the functions; functions should fail instead of succeeding.
Platforms tested:
Solaris 2.7 and Linux 2.2.18
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)
Bug fix (bug #777)
Description:
Current code allows a compound datatype to be inserted into itself.
Solution:
Check if the ID for the member is the same as the ID for the compound
datatype and reject it if so.
Platforms tested:
FreeBSD 4.5 (sleipnir)
Bug Fix for bug #789
Description:
Creating a 1-D dataset region reference caused the library to hang (go into
an infinite loop).
Solution:
Corrected algorithm for serializing hyperslab regions.
Platforms tested:
FreeBSD 4.5 (sleipnir)
Purpose:
Bug fix (#699), fix provided by a user, approved by Quincey
Description:
When a scalar dataspace was written to the file and then
subsequently queried with the H5Sget_simple_extent_type function,
type was reported H5S_SIMPLE instead of H5S_SCALAR.
Solution:
Applied a fix (see bug report 699) and modified out test program
to exercise the case.
Platforms tested:
Solaris 2.7 and Linux 2.2.18
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)
Feature Enhancement
Description:
We can now set the MPI_Info object to more than one key/value
pairing. By setting the HDF5_MPI_INFO environment variable to a
semicolon separated list of "key=value" pairs, we can set the
MPI_Info variable to them.
Platforms tested:
Linux
Feature
Description:
moved the routines of setting up and dumping MPI-info object to
test library so that it is avaiable for all tests too.
Platforms tested:
modi4(pp), eirene (serial)
Purpose:
added more tests to the H5set_extent function
Description:
there was a bug in the H5S_select_fill call when the fill value was not defined
added 2 more set of tests that call H5set_extent without the fill value being defined
there are now 4 sets of tests:
Test H5Dset_extent with chunks on the raw data cache, with and without fill value
Test H5Dset_extent with chunks written to file (b-tree routines), with and without fill value
Platforms tested:
w2000
linux
Bug Fix
Description:
Corrected int vs. unsigned short error that only showed up on big-endian
machines.
Also, add more testing to verify that the coordinates reported for each
element iterated through with H5Diterate are correct.
Platforms tested:
FreeBSD 4.5 (sleipnir)
Bug Fix
Description:
Selection offsets were not being used correctly when iterating through
all hyperslabs selections and point selections.
Solution:
Use the selection offset appropriately.
Platforms tested:
FreeBSD 4.5 (sleipnir)
Migrate from configure macros of XYZ_ABC to H5_XYZ_ABC
Description:
configure generates many macros definitions on the fly and
were stored in src/H5config.h which is included by H5public.h.
But other software that uses hdf5 may also run their own configure.
There can be a clash in macro name space. We decided awhile ago
to prepend all generated macros with "H5_" to avoid conflicts.
The process has started and this commit completes it (at least attempt
to).
Solution:
Many macros symbols (e.g. SIZEOF_xxx and HAVE_xxx were changed to
H5_SIZEOF_xxx and H5_HAVE_xxx). Then H5private.h no longer includes
H5config.h. This cuts H5config.h away from HDF5 source code.
Pending issues:
The module of fortran and pablo are to be resolved in a different
commit.
Platforms tested:
eirene (parallel), arabica (solaris 7 --enable-fortran, --enable-cxx)
Purpose:
New feature
Description:
Allow H5Glink and H5Gmove to handle links across different locations.
Solution:
Added H5Glink2 and H5Gmove2 functions with new parameter of destination
location.
Platforms tested:
Linux 2.2(eirene)
Bug Fix.
Description:
When the fill value for a dataset is not set, the size is set to zero,
causing problems with filling unused areas in previously defined chunks
(i.e. when the dataset shrinks in size)
Solution:
Use the size of the elements in the dataset directly, instead of relying on
the size of the fill value (which must be the same size).
Platforms tested:
FreeBSD 4.5 (sleipnir)
Code cleanup
Description:
Previously, the I/O pipeline (pline), external file list (efl) and fill-
value (fill) structs were passed down the raw data function call chain,
even into and/or through functions which didn't use them. Since all three
of these pieces of information are available from the dataset creation
property list, just pass the dataset creation property list down the
function call chain and query for the information needed in a particular
function.
Platforms tested:
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)
Purpose:
windows support of socket function
Description:
gethostname is treated as socket function in windows and
it is defined at winsock.h.
for every windows socket function to be called, it must start
with WSAStartup and end with WSACleanup
Solution:
Add WSAstartup and WSACleanup with WIN32 macro.
Platforms tested:
windows 2000, confirmed at linux 2.2.18
New feature
Description:
Added h5_show_hostname to display the hostname of the host in
which the process runs. It can help identify location of process
in multiple processes or batch launching environments.
Platforms tested:
Eirene (pp)
Feature
Description:
Added option -c to allow skipping file system Checking. This allows
users to run the test even if the program thinks it may fill up the
file system.
Platforms tested:
eirene
Code cleanup
Description:
Platform dependent code related to the struct stat and fstat
calls polluted source codes. Hard to maintain.
Solution:
Platform dependent code are moved to H5private.h and then internal
code can #include H5private.h. Repeat those macro definition for
the stdio and multi drivers since they area examples for writing
a virtual file driver. They must not use any internal code.
Platforms tested:
eirene (parallel), modi4 (serial including gass driver.)
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)
Purpose:
added a new file
Description:
new file that contains the framework for a new test, regarding a new ID to name
function. for the moment the program does nothing
Platforms tested:
w2000
Purpose:
Bug Fix
Description:
Reading fill_old.h5 from fillval.c has problem to find from building
directory.
Solution:
prepend source directory into file name.
Platforms tested:
Linux 2.2
Purpose:
New feature
Description:
Fill-value's behaviors for contiguous dataset have been redefined.
Basicly, dataset won't allocate space until it's necessary. Full details
are available at http://hdf.ncsa.uiuc.edu/RFC/Fill_Value, at this moment.
These two file test backward compatibility with 1.4.
Platforms tested:
Linux 2.2.
