New Features
============
Configuration:
--------------
- Started to support software conversion between long double and
integers. Hardware conversion will come very soon. SLU - 2005/1/6
- Intel v8.0 compiler would infinite loop when compiling some test
code with -O3 option. Changed enable-production default compiler
option to -O2. AKC - 2004/12/06
- Long double is assumed to be a supported C data type. It is a
stanadard C89 type. AKC - 2004/10/22
- The IA64 will use ecc as the C++ compiler by default.
- Added some initial support for making purify (or similar memory
checking products) happier by initializing buffers to zero and
disabling the internal free list code. To take advantage of this,
define 'H5_USING_PURIFY' in your CFLAGS when building the library.
QAK - 2004/07/23
- Fixed the long compile time of H5detect.c when v7.x Intel Compiler
is used with optimization NOT off. AKC - 2004/05/20
- Fixed configure setting of C++ for OSF1 platform. AKC - 2004/01/06
- Prefix default is changed from /usr/local to `pwd`/hdf5.
AKC - 2003/07/09
Library:
--------
- Pablo was removed from the source code EIP - 2005/01/21
- Modified registration of SZIP to dynamically detect the presence
or absence of the encoder. Changed configure and Makefiles,
and tests to dynamically detect encoder. BEM - 2004/11/02
- Added function H5Pget_data_transform, together with the previously
added H5Pset_data_transform, to support the data transform
feature. AKC - 2004/10/26
- Compound datatype has been enhanced with a new feature of size
adjustment. The size can be increased and decreased(without
cutting the last member) as long as it doesn't go down to zero.
No API change is involved. SLU - 2004/10/1
- Put back 6 old error API functions to be backward compatible with
version 1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear,
H5Eset_auto, H5Eget_auto. Their new equivalent functions are
called H5Epush_stack, H5Eprint_stack, H5Ewalk_stack,
H5Eclear_stack, H5Eset_auto_stack, H5Eget_auto_stack. SLU -
2004/9/2
- 4 new API functions, H5Tencode, H5Tdecode, H5Sencode, H5Sdecode were
added to the library. Given object ID, these functions encode and
decode HDF5 objects(data type and space) information into and from
binary buffer. SLU - 2004/07/21
- Modified the way how HDF5 calculates 'pixels_per_scanline' parameter for
SZIP compression. Now there is no restriction on the size and shape of the
chunk except that the total number of elements in the chunk cannot be
bigger than 'pixels_per_block' parameter provided by the user.
EIP - 2004/07/21
- Added support for SZIP without encoder. Added H5Zget_filter_info
and changed H5Pget_filter and H5Pget_filter_by_id to support this
change. JL/NF - 2004/06/30
- SZIP always uses K13 compression. This flag no longer needs to
be set when calling H5Pset_szip. If the flag for CHIP
compression is set, it will be ignored (since the two are mutually
exclusive). JL/NF - 2004/6/30
- A new API function H5Fget_name was added. It returns the name
of the file by object(file, group, data set, named data type,
attribute) ID. SLU - 2004/06/29
- Added support for user defined identifier types. NF/JL - 2004/06/29
- A new API function H5Fget_filesize was added. It returns the
actual file size of the opened file. SLU - 2004/06/24
- New Feature of Data transformation is added. AKC - 2004/05/03.
- New exception handler for datatype conversion is put in to
replace the old overflow callback function. This exception
handler is set through H5Pset_type_conv_cb function.
SLU - 2004/4/27
- Added option that if $HDF5_DISABLE_VERSION_CHECK is set to 2,
will suppress all library version mismatch warning messages.
AKC - 2004/4/14
- A new type of dataspace, null dataspace(dataspace without any
element) was added. SLU - 2004/3/24
- Data type conversion(software) from integer to float was added.
SLU - 2004/3/13
- Data type conversion(software) from float to integer was added.
Conversion from integer to float will be added later.
SLU -2004/2/4
- Added new H5Premove_filter routine to remove I/O pipeline filters
from dataset creation property lists. PVN - 2004/01/26
- Added new 'compare' callback parameter to H5Pregister & H5Pinsert
routines. QAK - 2004/01/07
- Data type conversion(hardware) between integers and floats was added.
SLU 2003/11/21
- New function H5Iget_file_id() was added. It returns file ID given
an object(dataset, group, or attribute) ID. SLU 2003/10/29
- Added new fields to the H5G_stat_t for more information about an
object's object header. QAK 2003/10/06
- Added new H5Fget_freespace() routine to query the free space in a
given file. QAK 2003/10/06
- Added backward compatability with v1.6 for new Error API. SLU -
2003/09/24
- Changed 'objno' field in H5G_stat_t structure from 'unsigned long[2]'
to 'haddr_t'. QAK - 2003/08/08
- Changed 'fileno' field in H5G_stat_t structure from 'unsigned long[2]'
to 'unsigned long'. QAK - 2003/08/08
- Changed 'hobj_ref_t' type from structure with array field to 'haddr_t'.
QAK - 2003/08/08
- Object references (hobj_ref_t) can now be compared with the 'objno'
field in the H5G_stat_t struct for testing if two objects are the
same within a file. QAK - 2003/08/08
- Switched over to new error API. SLU - 2003/07/25
Parallel Library:
-----------------
- Allow compressed, chunked datasets to be read in parallel.
QAK - 2004/10/04
- Add options of using atomicity and file-sync to test_mpio_1wMr.
AKC - 2003/11/13
- Added parallel test, test_mpio_1wMr, which tests if the
underlaying parallel I/O system is conforming to the POSIX
write/read requirement. AKC - 2003/11/12
Fortran Library:
----------------
- added new functions h5fget_name_f and h5fget_filesize_f
EIP 2004/07/08
- h5dwrite/read_f and h5awrite/read_f functions only accept dims parameter
of the type INTEGER(HSIZE_T).
Tools:
------
- new tool, h5jam. See reference manual. 2004/10/08
- h5repack.sh did not report errors encountered during tests. It does
now. AKC - 2004/04/02
- Added the MPI-I/O and MPI-POSIX drivers to the list of VFL drivers
available for h5dump and h5ls. RPM & QAK - 2004/02/01
- Added option --vfd= to h5ls to allow a VFL driver to be selected
by a user. RPM & QAK - 2004/02/01
- Added option -showconfig to compiler tools (h5cc,h5fc,h5c++).
AKC - 2004/01/08
- Install the "h5cc" and "h5fc" tools as "h5pcc" and "h5pfc"
respectively if library is built in parallel mode.
WCW - 2003/11/04
- Added metadata benchmark (perform/perf_meta). SLU - 2003/10/03
- Changed output of "OID"s from h5dump from "<number>-<number>" to
"<number". This affects both the "regular" and XML output.

Bug Fixes since HDF5-1.6.0 release
==================================
Library
-------
- Fix segmentation fault when calling H5Fflush with an attribute that
hasn't had a value written to it open. QAK - 2004/10/18
- Back up supporting bitfield and time types in H5Tget_native_type.
Leave it to future support. The function simply returns error
message of "not support" for bitfield and time types.
SLU - 2004/10/5
- Fixed address check in Core VFL driver to avoid spurious address/size
overflows for odd valued addresses and/or sizes. QAK - 2004/09/27
- Fixed parallel bug in which some processes attempted collective
I/O while others did independent I/O. Bug appeared when some
processes used point selections, and others didn't. JRM - 2004/9/15
- Corrected error where dataset region references were written in an
incorrect way on Cray machines. PVN & QAK - 2004/09/13
- The H5Tget_native_type now determines the native type for integers
based on the precision. This is to avoid cases of wrongly converting
an int to a short in machines that have a short of 8 bytes but with
32bit precision (e.g Cray SV1). PVN - 2004/09/07
- Changed H5Dread() to not overwrite data in an application's buffer
with garbage when accessing a chunked dataset with an undefined
fill value and an unwritten chunk is uncountered. QAK - 2004/08/25
- Fixed error which could cause a core dump when a type conversion
routine was registered after a compound datatype had been
converted and then an equivalment compound datatype was converted
again. QAK - 2004/08/07
- Fixed memory overwrite when encoding "multi" file driver information
for file's superblock. QAK - 2004/08/05
- Fixed obscure bug where a filter which failed during chunk allocation
could allow library to write uncompressed data to disk but think
the data was compressed. QAK - 2004/07/29
- Fixed bug where I/O to an extendible chunked dataset with zero-sized
dimensions would cause library to fail an assertion.
QAK - 2004/07/27
- Fixed bug where chunked datasets which have filters defined,
allocation time set to "late" and whose chunks don't align with
the dataspace bounds could have incorrect data stored when
overwriting the entire dataset on the first write. QAK - 2004/07/27
- Added check to ensure that dataspaces have extents set. JML-2004/07/26
- Fixed bug on some Solaris systems where HDF5 would try to use
gettimeofday() when that function didn't work properly.
JML - 2004/07/23
- Fixed bug in H5Sset_extent_simple where setting maximum size to
non-zero, then to zero would cause an error. JML - 2004/07/20
- Allow NULL pointer for buffer parameter to H5Dread & H5Dwrite
when not writing data ("none" selection or hyperslab or point
selection with no elements defined). QAK - 2004/07/20
- Calling H5Gcreate() on "/" or "." throws an error instead of
failing quietly. JML - 2004/07/19
- Fixed bug where setting file address size to be very small could
trigger an assert if the file grew to more than 64 KB. Now throws
an error and data can be recovered. JL/NF - 2004/07/14
- Fixed bug where "resurrecting" a dataset was failing.
QAK - 2004/07/14
- Fixed bug where incorrect data could be read from a chunked dataset
after it was extended. QAK - 2004/07/12
- Fixed failure to read data back from file of compound type with
variable-length string as field. SLU - 2004/06/10
- Fixed potential file corruption bug when a block of metadata could
overlap the end of the internal metadata accumulator buffer and
the buffer would be extended correctly, but would incorrectly
change it's starting address. QAK - 2004/06/09
- Opaque datatype with no tag failed for some operations. Fixed.
SLU - 2004/6/3
- Fixed potential file corruption bug where dimensions that were
too large (a value greater than could be represented in 32-bits)
could cause the incorrect amount of space to be allocated in a
file for the raw data for the dataset. QAK - 2004/06/01
- Fixed dtypes "sw long double -> double" failure in QSC class
machines. AKC - 2004/4/16
- Fixed problem with fletcher32 filter when converting data of different
endianess. PVN - 2004/03/10
- Fixed problem with H5Tget_native_type() not handling opaque fields
correctly. QAK - 2004/01/31
- Fixed several errors in B-tree deletion code which could cause a
B-tree (used with groups and chunked datasets) to become corrupt
with the right sequence of deleted objects. QAK - 2004/01/19
- Fixed small internal memory leaks of fill-value information.
QAK - 2004/01/13
- Fixed bug that caused variable-length datatypes (strings or sequences)
used for datasets in files with objects that were unlinked to
fail to be read/written to a file. QAK - 2004/01/13
- Detect situation where szip 'pixels per block' is larger than the
fastest changing dimension of a dataset's chunk size and disallow
this (due to limits in szip library). QAK - 2003/12/31
- Fixed bug with flattened hyperslab selections that would generate
incorrect hyperslab information with certain high-dimensionality
combinations of start/stride/count/block information.
QAK - 2003/12/31
- Fixed bug with variable-length datatypes used in compound datatypes.
SLU - 2003/12/29
- Fixed bug in parallel I/O routines that would cause reads from
"short datasets" (datasets which were only partially written out)
to return invalid data. QAK & AKC - 2003/12/19
- Fixed bug where scalar dataspaces for attributes were reporting as
simple dataspaces. QAK - 2003/12/13
- Fixed problem with selection offsets of hyperslab selections in
chunked datasets causing the library to go into an infinite loop.
QAK - 2003/12/13
- Fixed H5Giterate to avoid re-using index parameter after iteration
callback has been called (allows iteration callback to modify the
index parameter itself). QAK - 2003/12/06
- Fixed various floating-point conversion problems, including a
change which could corrupt data when converting from double->float.
QAK - 2003/11/24
- Changed "single process" metadata writing in library to collective
I/O by all processes, in order to guarantee correct data being
written with MPI-I/O. QAK - 2003/11/20
- Fixed problems with fill values and variable-length types and also
I/O on VL values that were set to NULL. QAK - 2003/11/08
- Fixed problems with MPI datatypes that caused ASCI Q machine to
hang. QAK - 2003/10/28
- Removed HDF5_MPI_PREFER_DERIVED_TYPES environment variable support,
since it had no benefit. QAK - 2003/10/28
- Single hyperslab selections (which were set with only one call to
H5Sselect_hyperslab) that had dimensions that could be "flattened"
but were interspersed with dimensions that could not be flattened
were not correctly handled, causing core dumps. QAK - 2003/10/25
- Fixed incorrect datatype of the third parameter to the Fortran90
h5pset(get)_cache_f subroutine (INTEGER to INTEGER(SIZE_T))
EIP - 2003/10/13
- Fixed problems with accessing variable-length data datatypes on
Crays. QAK - 2003/10/10
- Fixed potential file corruption bug when too many object header
messages (probably attributes, from a user perspective) were
inserted into an object header and certain other conditions were
met. QAK - 2003/10/08
- Changed implementation of internal ID searching algorithm to avoid
O(n) behavior for many common cases. QAK - 2003/10/06
- Allow partial parallel writing to compact datasets. QAK - 2003/10/06
- Correctly create reference to shared datatype in attribute, instead
of making a copy of the shared datatype in the attribute.
QAK - 2003/10/01
- Revert changes which caused files >2GB to fail when created with
MPI-I/O file driver on certain platforms. QAK - 2003/09/16

- Detect if a type is already packed before attempting to pack it
again or check if it is locked. SLU - 2003/09/10
- Corrected bug when opening a file twice with read-only permission
for one open and then closing the read-only access file ID would
generate an error. QAK - 2003/09/10
- Corrected bug in repeated calls to H5Pget_access_plist() which would
incorrectly manage reference counts of internal information and
eventually blow up. QAK - 2003/09/02
- Return rank of the array datatype on successful call to
H5Tget_array_dims(). QAK - 2003/08/30
- Corrected bug in H5Tdetect_class which was not correctly detecting
datatype classes of fields in nested compound datatypes in some
circumstances. QAK - 2003/08/30
- Corrected bug in sieve buffer code which could cause loss of data
when a small dataset was created and deleted in quick succession.
QAK - 2003/08/27
- Corrected bug in H5Gget_objname_by_idx which was not allowing NULL
for the name when just querying for the object name's length.
QAK - 2003/08/25
- Corrected bug in variable-length string handling which could
generate a core dump on writing variable-length strings as part
of a compound datatype on certain architectures. QAK - 2003/08/25

the size of certain compound datatypes and also incorrectly
compute the offset of the last field for those compound datatypes.
QAK - 2003/08/25
- Corrected bug in H5Tget_native_type which would drop string datatype
metadata (padding, etc.) QAK - 2003/08/25

environment variable has been removed. QAK - 2004/01/30
- Fixed the error that cause "make install" to fail because of the
macro definition syntax of "prefix?=..." AKC - 2003/07/22
Performance
-------------
- More optimizations to inner loops of datatype conversions for
integers and floats which give a 10-50% speedup. QAK - 2003/11/07
- Hoisted invariant 'if/else's out of inner datatype conversion loop for
integer and floating-point values, giving about a 20% speedup.
QAK - 2003/10/20
Tools
-----
- Fixed h5dump to print attributes data in ASCII if -r option is used.

- Fixed a segmentation fault of h5diff when percentage option is used.
AKC - 2003/08/27
- Switched away from tools using internal "fixtype" function(s) to use

Known Problems
==============
* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
messages like "INFO: 0031-XXX ...". This is from the command poe.
Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
and run the tests again.
The tests may fail with messages like "The socket name is already
in use". HDF5 does not use sockets (except for stream-VFD). This is
due to problems of the poe command trying to set up the debug socket.
Check if there are many old /tmp/s.pedb.* staying around. These are
sockets used by the poe command and left behind due to failed commands.
Ask your system administrator to clean them out. Lastly, request IBM
to provide a mean to run poe without the debug socket.
* The C++ library's tests fails when compiling with PGI C++ compiler. The
workaround until the problem is correctly handled is to use the
flag "--instantiate=local" prior to the configure and build steps, as:
setenv CXX "pgCC --instantiate=local" for pgCC 5.02 and higher
setenv CXX "pgCC -tlocal" for others
* The h5dump tests may fail to match the expected output on some platforms
(e.g. parallel jobs, 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 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 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.
* The Stream VFD was not tested yet under Windows. It is not supported
in the TFLOPS machine.
* 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:
- Cray J90 and Cray T90IEEE 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
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 site:
ftp://hdf.ncsa.uiuc.edu/pub/outgoing/hdf5/hdf5-1.6.2/F90_source_for_Crays
* On some platforms that use Intel and Absoft compilers to build HDF5 fortran library,
compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90
complaining about exit subroutine. Comment out the line
IF (total_error .ne. 0) CALL exit (total_error)
* On IA32 and IA64 systems, if you use a compiler other than GCC (such as
Intel's ecc or icc compilers), you will need to modify the generated
"libtool" program after configuration is finished. On or around line 104 of
the libtool file, there are lines which look like:
# How to pass a linker flag through the compiler.
wl=""
change these lines to this:
# How to pass a linker flag through the compiler.
wl="-Wl,"
UPDATE: This is now done automatically by the configure script. However, if
you still experience a problem, you may want to check this line in the
libtool file and make sure that it has the correct value.
* Information about building with PGI and Intel compilers is available in
INSTALL file sections 5.7 and 5.8
* On at least one system, (SDSC DataStar), the scheduler (in this case
LoadLeveler) sends job status updates to standard error when you run
any executable that was compiled with the parallel compilers.
This causes problems when running "make check" on parallel builds, as
many of the tool tests function by saving the output from test runs,
and comparing it to an exemplar.
The best solution is to reconfigure the target system so it no longer
inserts the extra text. However, this may not be practical.
In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to
the configure and build. This will cause "make check" to continue after
detecting errors in the tool tests. However, in the case of SDSC DataStar,
it also leaves you with some 150 "failed" tests to examine by hand.
A second solution is to write a script to run serial tests and filter
out the text added by the scheduler. A sample script used on SDSC
DataStar is given below, but you will probably have to customize it
for your installation.
Observe that the basic idea is to insert the script as the first item
on the command line which executes the the test. The script then
executes the test and filters out the offending text before passing
it on.
#!/bin/csh
set STDOUT_FILE=~/bin/serial_filter.stdout
set STDERR_FILE=~/bin/serial_filter.stderr
rm -f $STDOUT_FILE $STDERR_FILE
($* > $STDOUT_FILE) >& $STDERR_FILE
set RETURN_VALUE=$status
cat $STDOUT_FILE
tail +3 $STDERR_FILE
exit $RETURN_VALUE
You get the HDF make files and test scipts to execute your filter script
by setting the environment variable "RUNSERIAL" to the full path of the
script prior to running configure for parallel builds. Remember to
"unsetenv RUNSERIAL" before running configure for a serial build.
Note that the RUNSERIAL environment variable exists so that we can
can prefix serial runs as necessary on the target system. On DataStar,
no prefix is necessary. However on an MPICH system, the prefix might
have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to
get the serial tests to run at all.
In such cases, you will have to include the regular prefix in your
filter script.
