2002-04-30 04:27:31 +08:00
|
|
|
* Fixed bug where selection offsets were not being used when iterating
|
|
|
|
|
through point and hyperslab selections with H5Diterate(). QAK - 2002/04/29
|
2002-04-18 00:47:47 +08:00
|
|
|
* Fixed bug where the data for several level deep nested compound &
|
|
|
|
|
variable-length datatypes used for datasets were getting corrupted when
|
|
|
|
|
written to the file. QAK - 2002/04/17
|
2002-04-03 04:51:41 +08:00
|
|
|
* Fixed bug where selection offset was being ignored for certain hyperslab
|
|
|
|
|
selections when optimized I/O was being performed. QAK - 2002/04/02
|
|
|
|
|
* Added serial multi-gigabyte file size test. "test/big -h" shows
|
|
|
|
|
the help page. AKC - 2002/03/29
|
|
|
|
|
* Fixed bug where variable-length string type doesn't behave as
|
|
|
|
|
string. SLU - 2002/03/28
|
|
|
|
|
* Fixed bug in H5Gget_objinfo() which was not setting the 'fileno'
|
|
|
|
|
of the H5G_stat_t struct. QAK - 2002/03/27
|
|
|
|
|
* Fixed data corruption bug in hyperslab routines when contiguous
|
|
|
|
|
hyperslab that spans entire dimension and is larger than type
|
|
|
|
|
conversion buffer is attempted to be read. QAK - 2002/03/26
|
|
|
|
|
* Fixed bug where non-zero fill-value was not being read correctly from
|
|
|
|
|
certain chunked datasets when using an "all" or contiguous hyperslab
|
|
|
|
|
selection. QAK - 2002/02/14
|
|
|
|
|
* Fixed bug where a preempted chunk in the chunk data could still be
|
|
|
|
|
used by an internal pointer and cause an assertion failure or core
|
|
|
|
|
dump. QAK - 2002/02/13
|
|
|
|
|
* Fixed bug where raw data re-allocated from the free-list would sometimes
|
|
|
|
|
overlap with the metadata accumulator and get corrupted. QAK - 2002/01/23
|
|
|
|
|
* Fixed bug where variable-length datatypes for attributes was not working
|
2001-11-13 04:04:00 +08:00
|
|
|
correctly.
|
2002-04-03 04:51:41 +08:00
|
|
|
* Retired the DPSS virtual file driver (--with-gridstorage configure
|
|
|
|
|
option).
|
|
|
|
|
* Corrected behavior of H5Tinsert to not allow compound datatype fields to
|
|
|
|
|
be inserted past the end of the datatype.
|
|
|
|
|
* Fixed the internal macros used to encode & decode file metadata, to avoid
|
|
|
|
|
an unaligned access warning on IA64 machines.
|
2001-12-12 02:26:40 +08:00
|
|
|
* Fixed an off-by-one error in H5Sselect_valid when hyperslab selections
|
|
|
|
|
which would allow hyperslab selections which overlapped the edge of the
|
|
|
|
|
selection by one element as valid.
|
2002-04-03 04:51:41 +08:00
|
|
|
* Fixed a bug in internal B-tree code where a B-tree was not being copied
|
2002-01-05 04:52:43 +08:00
|
|
|
correctly.
|
2002-04-03 04:51:41 +08:00
|
|
|
* Fixed a bug in the 'big' test where quota limits weren't being detected
|
|
|
|
|
properly if they caused close() to fail.
|
|
|
|
|
* Fixed a bug where 'or'ing a hyperslab with a 'none' selection would
|
|
|
|
|
fail. Now adds that hyperslab as the first hyperlab in the selection.
|
|
|
|
|
* Fixed a bug where appending a point selection to the current selection
|
|
|
|
|
would not actually append the point when there were no points defined
|
|
|
|
|
currently.
|
|
|
|
|
* Fixed a bug where reading or writing chunked data which needed datatype
|
|
|
|
|
conversion could result in data values getting corrupted.
|
|
|
|
|
* Fixed a bug where reading an entire dataset wasn't being handled
|
|
|
|
|
optimally when the dataset had unlimited dimensions. Dataset is read
|
|
|
|
|
in a single low-level I/O now, instead of being broken into separate
|
|
|
|
|
pieces internally.
|
|
|
|
|
* Fixed a bug when reading chunked datasets where the edge of the dataset
|
|
|
|
|
would be incorrectly detected and generate an assertion failure.
|
|
|
|
|
* Added new parallel hdf5 tests in t_mpi. The new test checks if the
|
|
|
|
|
filesystem or the MPI-IO can really handle greater than 2GB files.
|
|
|
|
|
If it fails, it prints information message only without failing the
|
|
|
|
|
test.
|
|
|
|
|
* Fixed a bug in H5FD_mpio_flush() that might result in negative file seek
|
|
|
|
|
if both MPIO and Split-file drivers are used together.
|
|
|
|
|
* Fixed H5FDmpio.h to be C++ friendly by making Parallel HDF5 API's to be
|
|
|
|
|
external to C++.
|
|
|
|
|
* Fixed a bug of H5pubconf.h causing repeated definitions if it is included
|
|
|
|
|
more than once. hdf5.h now includes H5public.h which includes
|
|
|
|
|
H5pubconf.h. Applications should #include hdf5.h which handles multiple
|
|
|
|
|
inclusion correctly.
|
|
|
|
|
* Tweaked a few API functions to use 'size_t' instead of 'unsigned' or
|
|
|
|
|
'hsize_t', which may cause errors in some cases.
|
|
|
|
|
* Changed behavior of H5Tget_member_type to correctly emulate HDF5 v1.2.x
|
|
|
|
|
when --enable-hdf5v1_2 configure flag is enabled.
|
|
|
|
|
* Removed limitation that the data transfer buffer size needed to be
|
|
|
|
|
set for datasets whose dimensions were too large for the 'all' selection
|
|
|
|
|
code to handle. Any size dimensioned datasets should be handled
|
|
|
|
|
correctly now.
|
|
|
|
|
* The allocation by alignment (H5Pset_alignment) feature code somehow
|
|
|
|
|
got dropped in some 1.3.x version. Re-implemented it with "new and
|
|
|
|
|
improved" algorithm. It keeps track of "wasted" file-fragment in
|
|
|
|
|
the free-list too.
|
|
|
|
|
* IMPORTANT: Fixed file metadata corruption bug which could cause metadata
|
|
|
|
|
data loss in certain situations.
|
|
|
|
|
* Fixed build on Linux systems with --enable-static-exec flag. It now
|
|
|
|
|
works correctly.
|
|
|
|
|
* Fixed bug with non-zero userblock sizes causing raw data to not write
|
|
|
|
|
correctly.
|
|
|
|
|
* The RCSID string in H5public.h was causing the C++ compiling problem
|
|
|
|
|
because when it was included multiple times, C++ did not like multiple
|
|
|
|
|
definitions of the same static variable. All occurance of RCSID
|
|
|
|
|
definition are removed since we have not used it consistently before.
|
|
|
|
|
* Fixed bug where non-aligned hyperslab I/O on chunked datasets was
|
|
|
|
|
causing errors during I/O
|
|
|
|
|
* Fixed bug with contiguous hyperslabs not being detected, causing
|
|
|
|
|
slower I/O than necessary.

-------------
|
2001-08-28 03:31:45 +08:00
|
|
|
|
2002-04-03 04:51:41 +08:00
|
|
|
* Can use just enable-threadsafe if the C compiler has builtin pthreads
|
|
|
|
|
support.
|
2001-10-04 20:52:28 +08:00
|
|
|
* Require HDF (a.k.a. hdf4) software that consists of a newer version
|
|
|
|
|
of zlib library which consists of the compress2() function. Versions
|
|
|
|
|
HDF version 4.1r3 and newer meets this requirement. The compress2
|
|
|
|
|
uses a newer compression algorithm used by the HDF5 library. Also,
|
|
|
|
|
4.1r3 has an hdp tool that can handle "loops" in Vgroups.
|
2002-04-03 04:51:41 +08:00
|
|
|
* Added --enable-linux-lfs flag to allow more control over whether to enable
|
|
|
|
|
or disable large file support on Linux.
|
|
|
|
|
* Basic port to Compaq (nee DEC) Alpha OSF 5.
|
|
|
|
|
* Changed the default value of $NPROCS from 2 to 3 since 3 processes
|
|
|
|
|
have a much bigger chance catching parallel errors than just 2.

* Fixed limitation in h5dumper with object names which reached over 1024
|
|
|
|
|
characters in length. We can now handle arbitrarily larger sizes for
|
2002-04-03 04:51:41 +08:00
|
|
|
object names. BW - 2002/02/27
|
|
|
|
|
* Fixed so that the "-i" flag works correctly with the h5dumper.
|
|
|
|
|
* Fixed segfault when "-v" flag was used with the h5dumper.

New Features
|
|
|
|
|
============
|
2001-01-11 01:30:15 +08:00
|
|
|
|
2002-04-27 04:34:46 +08:00
|
|
|
* New functions H5Glink2 and H5Gmove2 were added to allow link and move to
|
|
|
|
|
be in different locations in the same file. The old functions H5Glink
|
|
|
|
|
and H5Gmove remain valid. SLU - 2002/04/26
|
2002-04-12 06:52:48 +08:00
|
|
|
* 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.
|
|
|
|
|
SLU - 2002/04/11
|
2002-04-09 20:47:34 +08:00
|
|
|
* Added new routine "H5Dfill" to fill a selection with a particular value
|
|
|
|
|
in memory. QAK - 2002/04/09
|
2002-04-06 06:31:20 +08:00
|
|
|
* A new query function H5Tget_member_index has been added for compound
|
|
|
|
|
and enumeration data types, to retrieve member's index by name.
|
|
|
|
|
SLU - 2002/04/05
|
2002-04-04 01:07:14 +08:00
|
|
|
* Improved performance of "regular" hyperslab I/O when using MPI-IO and the
|
|
|
|
|
datatype conversion is unneccessary. QAK - 2002/04/02
|
2002-04-03 04:51:41 +08:00
|
|
|
* Improved performance of single hyperslab I/O when datatype conversion is
|
|
|
|
|
unneccessary. QAK - 2002/04/02
|
|
|
|
|
* Added new "H5Sget_select_type" API function to determine which type of
|
|
|
|
|
selection is defined for a dataspace ("all", "none", "hyperslab" or
|
|
|
|
|
"point"). QAK - 2002/02/7
|
|
|
|
|
* Added support to read/write portions of chunks directly, if they are
|
|
|
|
|
uncompressed and too large to cache. This should speed up I/O on chunked
|
|
|
|
|
datasets for a few more cases. QAK - 2002/01/31
|
|
|
|
|
* Parallel HDF5 is now supported on HP-UX 11.00 platforms.
|
|
|
|
|
* Added H5Rget_obj_type() API function, which performs the same functionality
|
|
|
|
|
as H5Rget_object_type(), but requires the reference type as a parameter
|
|
|
|
|
in order to correctly handle dataset region references. Moved
|
|
|
|
|
H5Rget_object_type() to be only compiled into the library when v1.4
|
|
|
|
|
compatibility is enabled.
|
|
|
|
|
* Changed internal error handling macros to reduce code size of library by
|
|
|
|
|
about 10-20%.
|
|
|
|
|
* Added a new file access property, file close degree, to control file
|
|
|
|
|
close behavior. It has four values, H5F_CLOSE_WEAK, H5F_CLOSE_SEMI,
|
|
|
|
|
H5F_CLOSE_STRONG, and H5F_CLOSE_DEFAULT. Two correspont functions
|
|
|
|
|
H5Pset_fclose_degree and H5Pget_fclose_degree are also provided. Two
|
|
|
|
|
new functions H5Fget_obj_count and H5Fget_obj_ids are offerted to assist
|
|
|
|
|
this new feature. For full details, please refer to the reference
|
|
|
|
|
manual under the description of H5Fcreate, H5Fopen, H5Fclose and the
|
|
|
|
|
functions mentioned above.
|
|
|
|
|
* Removed H5P(get|set)_hyper_cache API function, since the property is no
|
|
|
|
|
longer used.
|
|
|
|
|
* Improved performance of non-contiguous hyperslabs (built up with
|
|
|
|
|
several hyperslab selection calls).
|
|
|
|
|
* Improved performance of single, contiguous hyperslabs when reading or
|
|
|
|
|
writing.
|
|
|
|
|
* As part of the transition to using generic properties everywhere, the
|
|
|
|
|
parameter of H5Pcreate changed from H5P_class_t to hid_t, as well
|
|
|
|
|
the return type of H5Pget_class changed from H5P_class_t to hid_t.
|
|
|
|
|
Further changes are still necessary and will be documented here as they
|
|
|
|
|
are made.
|
|
|
|
|
* Added a new test to verify the information provided by the configure
|
|
|
|
|
command.
|
|
|
|
|
* The H5Pset_fapl_split() accepts raw and meta file names similar to the
|
|
|
|
|
syntax of H5Pset_fapl_multi() in addition to what it used to accept.
|
|
|
|
|
* Added perform programs to test the HDF5 library performance. Programs
|
|
|
|
|
are installed in directory perform/.
|
|
|
|
|
* Added new checking in H5check_version() to verify the five HDF5 version
|
|
|
|
|
information macros (H5_VERS_MAJOR, H5_VERS_MINOR, H5_VERS_RELEASE,
|
|
|
|
|
H5_VERS_SUBRELEASE and H5_VERS_INFO) are consistent.
|
|
|
|
|
* Added a new public macro, H5_VERS_INFO, which is a string holding
|
|
|
|
|
the HDF5 library version information. This string is also compiled
|
|
|
|
|
into all HDF5 binary code which helps to identify the version
|
|
|
|
|
information of the binary code. One may use the Unix strings
|
|
|
|
|
command on the binary file and looks for the pattern "HDF5 library
|
|
|
|
|
version".
|
|
|
|
|
* Added a parallel HDF5 example examples/ph5example.c to illustrate
|
|
|
|
|
the basic way of using parallel HDF5.
|
|
|
|
|
* Added two simple parallel performance tests as mpi-perf.c (MPI
|
|
|
|
|
performance) and perf.c (PHDF5 performance) in testpar.
|
|
|
|
|
* Improved regular hyperslab I/O by about a factor of 6 or so.
|
|
|
|
|
* Modified the Pablo build procedure to permit building of the instrumented
|
|
|
|
|
library to link either with the Trace libraries as before or with the
|
|
|
|
|
Pablo Performance Caputure Facility.
|
|
|
|
|
* Verified correct operation of library on Solaris 2.8 in both 64-bit and
|
|
|
|
|
32-bit compilation modes. See INSTALL document for instructions on
|
|
|
|
|
compiling the distribution with 64-bit support.
|
|
|
|
|
* Parallel HDF5 now runs on the HP V2500 and HP N4000 machines.
|
|
|
|
|
* H5 <-> GIF convertor has been added. This is available under
|
|
|
|
|
tools/gifconv. The convertor supports the ability to create animated
|
|
|
|
|
gifs as well.
|
|
|
|
|
* Added a global string variable H5_lib_vers_info_g which holds the
|
|
|
|
|
HDF5 library version information. This can be used to identify
|
|
|
|
|
an hdf5 library or hdf5 application binary.
|
|
|
|
|
Also added a verification of the consistency between H5_lib_vers_info_g
|
|
|
|
|
and other version information in the source code.
|
|
|
|
|
* File sizes greater than 2GB are now supported on Linux systems with
|
|
|
|
|
version 2.4.x or higher kernels.
|
|
|
|
|
* F90 APIs are available on HPUX 11.00 and IBM SP platforms.
|
|
|
|
|
* F90 static library is available on Windows platforms. See
|
|
|
|
|
INSTALL_Windows.txt for details.
|
|
|
|
|
* F90 API:
|
|
|
|
|
- Added aditional parameter "dims" to the h5dread/h5dwrite and
|
|
|
|
|
h5aread/h5awrite subroutines. This parameter is 1D array of size
|
|
|
|
|
7 and contains the sizes of the data buffer dimensions.
|
2001-05-02 23:00:10 +08:00
|
|
|
* C++ API:
|
|
|
|
|
- Added two new member functions: Exception::getFuncName() and
|
|
|
|
|
Exception::getCFuncName() to provide the name of the member
|
|
|
|
|
function, where an exception is thrown.
|
|
|
|
|
- IdComponent::operator= becomes a virtual function because
|
|
|
|
|
DataType, DataSpace, and PropList provide their own
|
|
|
|
|
implementation. The new operator= functions invoke H5Tcopy,
|
|
|
|
|
H5Scopy, and H5Pcopy to make a copy of a datatype, dataspace,
|
|
|
|
|
and property list, respectively.
|
2002-04-03 04:51:41 +08:00
|
|
|
* 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.
|
2002-04-13 00:10:29 +08:00
|
|
|
* New API function H5Dset_extent. Modifies the dimensions of a dataset,
|
|
|
|
|
allows change to a lower dimension. The unused space in the file is freed.

Known Problems
|
2000-03-24 05:34:06 +08:00
|
|
|
==============
|
2002-01-08 03:45:21 +08:00
|
|
|
* Datasets or attributes which have a variable-length string datatype are not
|
|
|
|
|
printing correctly with h5dump and h5ls.
|
|
|
|
|
|
2001-10-06 00:59:21 +08:00
|
|
|
* DLLs do not work on Windows 98
|
|
|
|
|
|
|
|
|
|
* RELEASE DLLs will fail on some tests on Windows 2000 with Microsoft visual
|
|
|
|
|
studio 6.0 due to memory allocation problems caused by compiler.
|
|
|
|
|
Users are encouraged to go to microsoft site to find and install
|
|
|
|
|
visual studio 6.0 service pack 5. After that, release dlls will work.
|
2000-03-24 05:34:06 +08:00
|
|
|
|
2001-08-28 03:31:45 +08:00
|
|
|
* 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.
|
2001-02-21 03:35:07 +08:00
|
|
|
|
2001-02-01 01:28:57 +08:00
|
|
|
* 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.
|
|
|
|
|
|
2001-02-21 03:35:07 +08:00
|
|
|
The --enable-static-exec configure flag also fails to correctly compile
|
2001-05-26 02:49:33 +08:00
|
|
|
on IBM SP2 platform for the serial mode. The parallel mode works fine
|
2001-02-21 03:35:07 +08:00
|
|
|
with this option.
|
|
|
|
|
|
2001-02-01 01:28:57 +08:00
|
|
|
It is suggested that you don't use this option on these platforms
|
|
|
|
|
during configuration.
|
|
|
|
|
|
2001-01-19 05:11:33 +08:00
|
|
|
* 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:
|
2001-01-12 06:47:33 +08:00
|
|
|
|
2001-01-19 05:11:33 +08:00
|
|
|
warning: ANSI C does not support `long long'
|
|
|
|
|
|
|
|
|
|
This warning is innocuous and can be safely ignored.
|
2001-01-12 06:47:33 +08:00
|
|
|
|
2000-12-19 06:06:13 +08:00
|
|
|
* SunOS 5.6 with C WorkShop Compilers 4.2: Hyperslab selections will
|
2000-03-24 05:34:06 +08:00
|
|
|
fail if library is compiled using optimization of any level.
|
2000-02-10 05:36:37 +08:00
|
|
|
|
2001-08-28 03:31:45 +08:00
|
|
|
* 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.
|
2001-02-10 06:37:18 +08:00
|
|
|
|
2001-08-28 03:31:45 +08:00
|
|
|
* The Stream VFD was not tested yet under Windows. It is not supported
|
|
|
|
|
in the TFLOPS machine.
|
2000-12-19 06:06:13 +08:00
|
|
|
|
2001-08-28 03:31:45 +08:00
|
|
|
* Shared library option is broken for IBM SP and some Origin 2000
|
|
|
|
|
platforms. One needs to run ./configure with '--disable-shared'
|
2000-12-19 06:06:13 +08:00
|
|
|
|
|
|
|
|
* 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
|
2000-12-20 01:44:28 +08:00
|
|
|
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.
|
2000-12-20 00:08:47 +08:00
|
|
|
|
|
|
|
|
* Certain platforms give false negatives when testing h5ls:
|
2001-08-28 03:31:45 +08:00
|
|
|
|
2000-12-20 00:08:47 +08:00
|
|
|
- Solaris x86 2.5.1, Cray T3E and Cray J90 give errors during testing
|
2001-08-28 03:31:45 +08:00
|
|
|
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.
|
|
|
|
|
|
2000-12-20 00:08:47 +08:00
|
|
|
- Cray J90 (and Cray T3E?) give errors during testing when displaying
|
2001-08-28 03:31:45 +08:00
|
|
|
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.
|
2001-01-30 06:52:32 +08:00
|
|
|
|
|
|
|
|
* Before building HDF5 F90 Library from source on Crays (T3E and J90)
|
2001-08-28 03:31:45 +08:00
|
|
|
replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src
|
|
|
|
|
subdirectory in the top level directory with the Cray-specific files
|
