|
|
file in the HDF5 source.

Bug Fixes since HDF5-1.4.0
|
|
==========================
|
|
|
|
Library
|
|
-------
|
|
* Fixed bug with contiguous hyperslabs not being detected, causing
|
|
slower I/O than necessary.
|
|
* Fixed bug where non-aligned hyperslab I/O on chunked datasets was
|
|
causing errors during I/O

Known Problems
|
|
==============
|
|
|
|
* The stream-vfd test uses ip port 10007 for testing. If another application
|
|
is already using that port address, the test will hang indefinitely and
|
|
has to be terminated by the kill command. To try the test again, change
|
|
the port address in test/stream_test.c to one not being used in the host.
|
|
|
|
* The --enable-static-exec configure flag fails to compile for Solaris
|
|
platforms. This is due to the fact that not all of the system
|
|
libraries on Solaris are available in a static format.
|
|
|
|
The --enable-static-exec configure flag also fails to correctly compile
|
|
on Linux platforms using the gcc-2.95.2 compiler.
|
|
|
|
The --enable-static-exec configure flag also fails to correctly compile
|
|
on IBM SP2 platform for the serial mode. The parallel mode works fine
|
|
with this option.
|
|
|
|
It is suggested that you don't use this option on these platforms
|
|
during configuration.
|
|
|
|
* With the gcc 2.95.2 compiler, HDF 5 uses the `-ansi' flag during
|
|
compilation. The ANSI version of the compiler complains about not being
|
|
able to handle the `long long' datatype with the warning:
|
|
|
|
warning: ANSI C does not support `long long'
|
|
|
|
This warning is innocuous and can be safely ignored.
|
|
|
|
* SunOS 5.6 with C WorkShop Compilers 4.2: Hyperslab selections will
|
|
fail if library is compiled using optimization of any level.
|
|
|
|
* When building hdf5 tools and applications on windows platform, a linking
|
|
warning: defaultlib "LIBC" conflicts with use of other libs will appear
|
|
on debug version when running VC++6.0. This warning doesn't affect building
|
|
and testing hdf5 applications. We will continue investigating this.
|
|
|
|
* h5toh4 converter fails two cases(tstr.h5 and tmany.h5) for release dll version on
|
|
windows 2000 and NT. The reason is possibly due to windows NT DLL
|
|
convention on freeing memory. It seems that memory cannot be free
|
|
across library or DLL. It is still under investigated.
|
|
|
|
* The Stream VFD was not tested yet under Windows.
|
|
It is not supported in the TFLOPS machine.
|
|
|
|
* Shared library option is broken for IBM SP and some Origin 2000 platforms.
|
|
One needs to run ./configure with '--disable-shared'
|
|
|
|
* The ./dsets tests failed in the TFLOPS machine if the test program,
|
|
dsets.c, is compiled with the -O option. The hdf5 library still works
|
|
correctly with the -O option. The test program works fine if it is
|
|
compiled with -O1 or -O0. Only -O (same as -O2) causes the test
|
|
program to fail.
|
|
|
|
* Certain platforms give false negatives when testing h5ls:
|
|
- Solaris x86 2.5.1, Cray T3E and Cray J90 give errors during testing
|
|
when displaying object references in certain files. These are benign
|
|
differences due to the difference in sizes of the objects created on
|
|
those platforms. h5ls appears to be dumping object references
|
|
correctly.
|
|
- Cray J90 (and Cray T3E?) give errors during testing when displaying
|
|
some floating-point values. These are benign differences due to the
|
|
different precision in the values displayed and h5ls appears to be
|
|
dumping floating-point numbers correctly.
|
|
|
|
* Before building HDF5 F90 Library from source on Crays (T3E and J90)
|
|
replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src subdirectory
|
|
in the top level directory with the Cray-specific files from the
|
|
ftp://hdf.ncsa.uiuc.edu/pub/ougoing/hdf5/hdf5-1.4.0-beta/F90_source_for_Crays
|
|
directory.
|
|
|
|
* The h4toh5 utility produces images that do not correctly conform
|
|
to the HDF5 Image and Palette Specification.
|
|
|
|
http://hdf.ncsa.uiuc.edu/HDF5/doc/ImageSpec.html
|
|
|
|
Several required HDF5 attributes are omitted, and the dataspace
|
|
is reversed (i.e., the ht. and width of the image dataset is
|
|
incorrectly described.) For more information, please see:
