the generanted hdf files against saved output of hdp. This did not
work well because whenever the hdp changes its output format, the
tests failed unnecessarily. The tests also failed if the test machine
uses a different version of HDF library from the HDF5 development
machine.
Changed the algorithm to compare the generated HDF files against
saved HDF files (first by a simple cmp; if that fails, compare the
output of the host machine's hdp on both HDF files.)
Saved HDF files are stored in testfiles/Expected.
Tested on Hawkwind (FreeBSD) with srcdir option and Baldric (Solaris)
without srcdir option.
New feature
Problem:
The h5toh4 converter tester - testh5toh4, is set up to place output
files in same directory as input files. A difficulty comes up when
the input files come off a write-protected media, such-as CDROM.
Solution:
Rather than using "cd" to change directory and referencing files by
short filename only, "input directory" and "output directory" are
defined explicitly, and files are always referenced with pathnames
included. For cases when the converter generates the output filename,
a copy of the input file is first placed in the "output directory".
The copied input file is used by h5toh4 and then removed.
On Solaris2.5, the following sequence of commands seemed to work fine:
$ gunzip < hdf5-1.1.72.tar.gz | tar xf -
$ chmod -R ugo-w hdf5-1.1.72
$ mkdir build
$ cd build
$ ../hdf5-1.1.72/configure --enable-production --disable-debug \
$ --with-hdf4=... --with-zlib=...
$ make check
This change should allow the tester to be used when the hdf5 source
is on a read only media like a CDROM.
Platform tested:
Solaris2.5
Bug fix
Problem:
The hdp dumper output files used in the h5toh4 converter test
program have the result of the latest changes to the HDF4 library,
but the converter was to maintain compatability with HDF4.1r2.
Solution:
Regenerate the HDF4.1r2 version of the hdp dumper ouput files to
be used for the h5toh4 converter test program.
Platform tested:
Solaris2.5
New feature
Solution:
Modified h5dumptst.c to generate more single dimension
datasets of H5T_STRING type held in file tstr2.h5.
Platform tested:
Solaris2.5
Conform closer to other test print-out.
Solution:
Added "All h5dump tests passed." statement to output
of testh5dump.sh when appropriate. Similarly, added
"All h5toh4 tests passed." statement to output of
testh5toh4 when appropriate.
Also, added the testing of converting H5 files with
loop pathways into H4 files with recursive references.
Platforms tested:
Solaris2.5, Digital Unix 4.0
New feature
Solution:
Added some new new tests to show that paths involving HARDLINKS
and paths involving SOFTLINKS convert existing objects from H5 to
H4 the same way that paths involving no links does.
Platform tested:
Solaris2.5

./INSTALL
Added warning that enabling debugging code can adversely
affect performance even when the debugging isn't turned on at
run-time. Performance testing shows that under certain
circumstances (like data type conversions of compound types)
the H5_timer functions, although only a few lines each,
contribute a fairly large percent to the execution time.
./src/H5T.c
./src/H5Tpkg.h
./src/H5Tpublic.h
Improved the H5Tunregister() function to make unregistering
more flexible. It takes the same arguments as H5Tregister()
but also accepts wild cards. All conversion functions that
match the H5Tunregister() search criteria are removed from the
global type conversion table.
The H5Tregister_hard() and H5Tregister_soft() were combined
into a single function called H5Tregister() which is the
counterpart to H5Tunregister(). A new `persistence' argument
was added to differentiate between the two types of conversion
functions.
The application is allowed to register a hard conversion
function for the no-op conversion path although the library
isn't obligated to call it (it usually does). This is mostly
for completeness, but the application might use it to help
determine if the raw data pipeline was able to use the
optimized path for the case when no type conversion is
necessary. The library doesn't allow this path to be
unregistered although the application can redefine it as often
as it likes.
Fixed the type conversion tables in preparation for MT-safety
and to fix previosly-known design bugs wrt. unregistering
conversion functions or changing the C function associated
with a conversion path. The MT-safety stuff is documented in a
separate white paper.
Increased the conversion function debugging name from 9
characters to 31 characters so the output can be more
descriptive.
Moved conversion path statistics from the H5T_cdata_t member
into the conversion path itself. This makes H5T_cdata_t
contain only application-visible data structures.
./src/H5A.c
./src/H5D.c
./src/H5Ofill.c
./src/H5P.c
./src/H5T.c
Improved the way type conversion functions are called so the
caller doesn't have to check for data type debugging and
increment type conversion timers and statistics.
Changed check for no-op conversion since it is now
application-definable and there may even be more than one
definition at a time in a multi-threaded application (one
thread might be using the no-op conversion path when some
other thread changes its definition -- the first thread still
sees the original defintion until it's done with the
operation).
./doc/html/Datatypes.html
Updated the user guide to reflect the changes to data type
conversion registration functions.
./bin/trace
./src/H5.c
Added tracing support for the new H5T_pers_t data type.
./test/dtypes.c
Added printf to display alignment value if non-aligned data
types are being tested.
./test/h5test.c
Modified the H5Tunregister() calls to use the new
arguments. All 94 of those calls can be replaced by a single
call to the new H5Tunregister() function.
./src/H5.c
Added HAVE_GETTIMEOFDAY around an auto variable and
initialized the elapsed time to zero when gettimeofday() is
not available.
./src/H5F.c
./src/H5Fprivate.h
./src/H5P.c
Added an H5*_init() functions which do the same thing as
H5*_init_interface() but can be called from other packages and
don't do anything if the interface is already initialized.
This fixes a couple memory leaks in applications that
repeatedly close and open the library with H5close().
./src/H5Tconv.c
Optimized some data alignment code in the hardware conversion
functions.
Hardware conversions accumulate statistics about source and
destination data alignment and print that information when the
conversion function is unregistered (usually when the
application exits) if data type debugging is compiled into the
library and enabled at run-time.
The conversion caching was cleaned up for the compound data
type conversion function. It now caches conversion paths in a
manner that will be MT-safe and is much simpler than the old
method. Also cleaned up some array index maps.
./src/H5detect.c
Fixd mispelling of alingemnt.
./src/H5private.h
Changed `TRUE' to `1' in assignment to interface_initialize_g
in FUNC_ENTER macro definition.
./tools/testh5dump.sh
Completely rewritten to make it shorter, better documented,
and conforming to most of the other test outputs.
The comparison of the actual output with the expected output
is insensitive to differences in white space. The test now
passes for the first time on Linux where the output width
wasn't as expected but the output was otherwise correct.
