|
|
|
This document describes the differences between HDF5-1.4.2 and
|
|
HDF5-1.4.2-post0, and contains information on the platforms tested and
|
|
known problems in HDF5-1.4.2-post0. For more details check the HISTORY.txt
|
|
file in the HDF5 source.

New Features
|
|
============
|
|
|
|
* A helper script called ``h5cc'', which helps compilation of HDF5
|
|
programs, is now distributed with HDF5. See the reference manual
|
|
for information on how to use this feature.
|
|
* Added perform programs to test the HDF5 library performance. Programs
|
|
are installed in directory perform/.
|
|
* Improved performance of byte-swapping during data conversions.
|
|
* Changed prototype for H5Awrite from:
|
|
H5Awrite(hid_t attr_id, hid_t type_id, void *buf)
|
|
to:
|
|
H5Awrite(hid_t attr_id, hid_t type_id, const void *buf)
|

Footnotes: (1) Using mpich.
|
|
(2) Using mpt and mpich.
|
|
(3) When configured with static-exec enabled, tests fail
|
|
in serial mode.
|
|
(4) No HDF4-related tools.
|
|
(5) Shared libraries are provided only for the C library.

Known Problems
|
|
==============
|
|
|
|
* When a dataset with the variable-legth datatype is overwritten,
|
|
the library can develop memory leaks that cause the file to become
|
|
unnecessarily large. This is planned to be fixed in the next release.
|
|
|
|
* On the SV1, the h5ls test fails due to a difference between the
|
|
SV1 printf precision and the printf precision on other platforms.
|
|
|
|
* The h5dump tests may fail to match the expected output in some
|
|
platforms (e.g. SP2 parallel, Windows) where the error messages
|
|
directed to "stderr" do not appear in the "right order" with output
|
|
from stdout. This is not an error.
|
|
|
|
* The --enable-static-exec configure flag fails to compile for HP-UX
|
|
11.00 platforms.
|
|
|
|
* The executables are always dynamic on IRIX64 6.5(64 and n32) and
|
|
IRIX 6.5 even if they are configured with --enable-static-exec.
|
|
|
|
* IRIX 6.5 fails to compile if configured with --enable-static-exec.
|
|
|
|
* After "make install" or "make install-doc" one may need to reload
|
|
the source from the tar file before doing another build.
|
|
|
|
* The HDF5_MPI_OPT_TYPES optimization code in the parallel HDF5 will cause
|
|
a hang in some cases when chunked storage is used. This is now set to
|
|
be off by default. One may turn it on by setting environment variable
|
|
HDF5_MPI_OPT_TYPES to a non-zero value such as 1.
