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
bug fix plus minor modifications
Description:
The nbit filter makes a wrong assumption that function H5Z_set_local_nbit
and H5Z_filter_nbit will be called together. It uses 2 local variables
outside these functions to pass information from H5Z_set_local_nbit to
H5Z_filter_nbit.
Solution:
Store the two variables in cd_values[], which can be retrieved when
H5Z_filter_nbit is called independently.
Platforms tested:
heping, copper
Misc. update:
Bug fix.
Description:
Quincey changed "entern H5_DLL" to "H5_DLLVAR" in hdf5/src/H5FLprivate.h which caused some symbols can not be exported correctly by HDF5 DLL.
Solution:
Change "H5_DLLVAR" back to "extern H5_DLL".
Platforms tested:
Visual C++ 6.0 on Windows XP.
.NET 2003 on Windows XP.
Heping (Linux 2.4).
(Note: I talked with Elena and Quincey about this failure. Quincey asked me to check in this fix.)
Misc. update:
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
Description: The byte order for all 1-byte integer types was fixed as little-endian
even on a big-endian machine. This's corrected in h5detect.c. When types are only
1 byte long, a native int is used substitute the type to detect byte order. Some tools
like h5dump and h5repack are also corrected in this case.
Platforms tested: fuss, copper, sol.(There're some failures from the recent configure
change).
Misc. update: Information in the RELEASE.txt.
Bug fix
Description:
Correct the record count for the newly split root node
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Too minor to require h5committest
New feature
Description:
Expand v2 B-tree code to support splitting the root node when enough
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)
New feature
Description:
Add basic code for new B-tree implementation. They don't do much yet,
aren't hooked up to anything yet and the format may change, but I'd like to
start getting them into the daily tests.
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)
Bug fix
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
Tests modification and improvements of nbit filter.
Description:
Add dynamic allocation of array storing nbit parameters and check if
the number of parameters exceeds what cd_values[] can store; change
function prototypes to improve poratability; minor modification to
improve efficiency of the nbit algorithm.
Platforms tested:
AIX 5.1 and Linux 2.4.
Misc. update:
Bug fix
Description:
Catch another way that vsnprintf() can fail (this time on the HP) and
deal with that.
Platforms tested:
HP/UX 11.x (kelgia)
Doesn't affect other platforms
Bug fix
Description:
Add detect vasprintf() routine and use it instead of vsnprintf() when
formatting error descriptions if it's available.
Added configure test to detect "broken" vsnprintf() implementations which
don't return the correct number of character for strings that are too long to
fit into the buffer provided (currently a problem on the SGIs and probably the
HP).
Re-wrote error formatting code in H5Epush_stack() to handle broken
vsnprintf() implementations, etc.
Platforms tested:
IRIX64 6.5 (modi4)
h5committest
Description: Removed PABLO from the source
Solution:
Platforms tested: arabica with 64-bit, copper with parallel,
heping with GNU C and C++ and PGI fortran (but
I disabled hl, there is some weird problem only
on heping: F9XMODFLAG is not
propagated to the Makefile files
Misc. update:
For N-bit filter,
Adding parameter mappings from HDF5 compound datatype, array datatype and atomic datatype
to cd_values inside HDF5 library.
N-bit filter should work with these datatypes(string and variable length datatype haven't been
considered) in the near future.
Description:
This is for debugging purpose, N-bit filter won't be tested in the daily test.
Solution:
Platforms tested:
AIX 5.1 and Linux 2.4. Arabica is too slow. Hopefully shanti can be used soon.
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:
Bug fix
Description:
Correctly retire the H5E_LEN setting, now that the FORTRAN and C++ APIs
have been corrected to not use it either.
Solution:
Pass in the string buffer length for FORTRAN
In the C++ API, call H5Eget_msg() in a manner similar to the way
H5Fget_name() is called.
Platforms tested:
Linux 2.4 (heping) w/FORTRAN & C++
Solaris 2.7 (arabica) w/FORTRAN & C++
Bug fix
Description:
Calling HDvsnprintf() several times (should be twice) is incorrect
without calling va_end() and va_start() again.
Solution:
Call va_end() and va_start() before calling HDvsnprintf() again.
Platforms tested:
Linux 2.4/x86_64 (mir)
Too minor to require h5committest
Bug fix
Description:
Fortran and C++ API failed to compile because they need to use
H5E_LEN which was removed.
Solution:
Restored the H5E_LEN definition.
A permenant solution is still needed.
Platforms tested:
H5committested. (heping, sol, and copper all compiled fine again but
sol had an error in testerror.sh which seemed to be a different
problem.
Also tested in tg-NSCA.
Description: Intel compiler on Linux has some problem to convert long double to
unsigned int correctly.
Solution: Detect the problem in configure and define a macro to skip this test
if it happens.
Platforms tested: eirene and fuss. Simple change.
Bug fix
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
cleanup warning messages.
Description:
Compilers complained about local variable shadowed global variables.
The global variables d[], m[], nd, na were having the same names
as local function arguments. This was a left over when I broke the
original one big chunk of code into separated functions to go around
the Intel Compiler optimization error.
Solution:
Appended the global variables with suffix _g, thus
d[] => d_g[]
m[] => m_g[]
nd => nd_g
na => na_g
This is only an intermediate step. After the changes tested
out fine by all machines, need to rename the variables to more
meaningful names like dtype_array.
Platforms tested:
Tested in heping by saving the previous generated H5Tinit.c,
regenerated a new H5Tinit.c with the changed code, finally
compared the new and old versions were identical.
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.
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.
Platforms tested: modi4, kelgia, fuss
Bug fix
Description:
Print the thread ID in a little more portable of a fashion, disallowing
negative thread IDs.
Platforms tested:
Linux 2.4 (heping) w/threadsafe
Too Minor to require h5committest
Remove feature
Description:
Retire threaded, balanced binary tree code from HDF5 use. Requiescat in
pace...
Also, regenerate dependencies files.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require full h5committesting (the code is already
disconnected from everything except its tests)
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)
Code cleanup
Description:
Transition FPHDF5 to use skip lists for various internal data structures,
instead of threaded, balanced binary trees.
Also, simplify some of FPHDF5 code some, etc.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel & fphdf5
Too minor to require h5committest
New feature
Description:
Add some additional features to the skip list code that was needed to
fully support all the features that the threaded, balanced binary tree code
has.
Also, updated the property list code to take advantage of a few of the
new features.
Platforms tested:
FreeBSD 4.10 (sleipnir)
Too minor to require h5committest
Bug fix.
Description:
threadsafe test (ttsafe) would seg-fault if --disable-production --enable-debug
mode is used. Reason was that the fstack.nused field was not initialized
when created.
Solution:
Init new fstack.nused with 0.
Platforms tested:
Tested in mir, using development/debug mode.
Did not "h5committested" as change is trivial and limited to threadsafe mode.
To add n-bit implementation inside HDF5.
Description:
This check-in for implementation is for debugging purpose.
N-bit filter should be used for the time being.
Solution:
Platforms tested:
sol 2.7, Linux 2.4, Aix 5.1
Misc. update:
Adding framework of N-bit filter
Description:
N-bit filter is required for NetCDF project.
To add N-bit filter, configure.in configure, Makefile.in under src and other
filter-related source code needs to be updated.
Currently, N-bit tests are turned off from the library. So the change will affect daily test.
Solution:
Platforms tested:
sol 2.7, linux 2.4, aix 5.1
Misc. update:
Description: Start to support software conversion between long double and
all integers.
Solution: No major changes to the algorithm. Changes to configure is to
exclude SGI for long double to integers test because there're too many problems
in their compiler.
Platforms tested: h5committest, modi4, fuss, Teragrid, arabica
Misc. update: RELEASE.txt
Bug fix.
Description:
When building H5Z.c with Visual C++ 6.0, I got the following warning message:
H5Z.c(1241) : warning C4013: 'SZ_encoder_enabled' undefined; assuming extern returning int
Solution:
The header file szlib.h should be included in H5Z.c in order to use SZ_encoder_enabled() function.
Add the following script into H5Z.c:
#ifdef H5_HAVE_SZLIB_H
# include "szlib.h"
#endif
Platforms tested:
Heping (Linux)
Visual C++ 6.0 on Windows XP/2000.
.NET on Windows XP.
(Tested with SZIP-with-encoder and SZIP-without-encoder).
