CONTENTS
========
- New Features
- Support for New Platforms, Languages, and Compilers
- Bug Fixes since HDF5-1.8.6
- Platforms Tested
- Supported Configuration Features Summary
- Known Problems
New Features
============
Configuration
-------------
- Configure now generates Makefiles that build in "silent make mode"
by default in which compile and link lines are significantly
simplified for clarity. To override this and view actual compile and
link lines during building, the --disable-silent-rules flag can be used
at configure time, or the 'make' command can be followed by V=1, to
indicate a "verbose" make. (MAM - 2011/4/14).
- Added mpicc and mpif90 as the default C and Fortran compilers for Linux
systems when --enable-parallel is specified but no $CC or $FC is defined.
(AKC - 2011/2/7)
- Added a new configure option, "--enable-unsupported", which can
be used to stop configure from preventing the use of unsupported
configure option combinations, such as c++ in parallel or Fortran
with threadsafe. Use at your own risk, as it may result in a
library that won't compile or run as expected!
(MAM - 2010/11/17 - Bug 2061)
Library
-------
- Added ability to cache files opened through external links. Added new
public functions H5Pset_elink_file_cache_size(),
H5Pget_elink_file_cache_size(), and H5Fclear_elink_file_cache().
(NAF - 2011/02/17)
- Finished implementing all options for 'log' VFD. (QAK - 2011/1/25)
- Removed all old code for Metraowerks compilers, bracketed by
__MWERKS__). Metraowerks compiler is long gone. (AKC - 2010/11/17)
Parallel Library
----------------
- None
Tools
-----
- h5diff: Added new "verbose with levels" option, '-vN, --verbose=N'.
The old '-v, --verbose' option is deprecated but remains available;
it is exactly equivalent to '-v0, --verbose=0'.
The new levels 1 ('-v1' or '--verbose=1') and 2 ('-v2' or
'--verbose=2') can be specified to view more information regarding
attributes differences. Bug #2121 (JKM 2011/3/23)
- h5dump: Added new option --enable-error-stack. This option will
display error stack information in the output stream. This is
useful when the "h5dump: Unable to print data" message is output.
(ADB - 2011/03/03)

Support for New Platforms, Languages, and Compilers
===================================================
- Intel V11.1 uses now -O3 optimization in production mode (EIP - 2010/10/08)
Bug Fixes since HDF5-1.8.6
==========================
Configuration
-------------
- Removed config/ibm-aix6.x. All IBM-AIX settings are in one file,
ibm-aix. (AKC - 2011/4/14)
- Shared C libraries are no longer disabled on Mac when Fortran
is enabled. Shared Fortran libraries are still not supported on Mac,
so configure will disable them by default, but this is overrideable
with the new --enable-unsupported configure option. The configure
summary has been updated to reflect the fact that the shared-ness of
the C++/Fortran wrapper libraries may not align with the C library.
(MAM - 2011/04/11 - HDFFV-4353).
Library
-------
- Changed assertion failure when decoding a compound datatype with no
fields into a normal error failure. Also prohibit using this sort
of datatype for creating an attribute (as is already the case for
datasets and committed (named) datatypes). (QAK - 2011/04/15, Jira
issue #HDFFV-2766)
- Tell the VFL flush call that the file will be closing, allowing
the VFDs to avoid sync'ing the file (particularly valuable in parallel).
(QAK - 2011/03/09)
- The datatype handler created with H5Tencode/decode used to have the
reference count 0 (zero); it now has the reference count 1 (one).
(SLU - 2011/2/18)
- Fixed the definition of H5_HAVE_GETTIMEOFDAY on Windows so that
HDgettimeofday() is defined and works properly. Bug HDFFV-5931
(DER - 2011/04/14)
- Added basic VFD tests for the Windows, STDIO and log VFD tests. The
STDIO test is skipped for now due to failures on a few older platforms
(see "known problems", below).
(DER - 2011/04/11)
Parallel Library
----------------
- None
Tools
-----
- Updated h5dump test case script to prevent entire test failure when
source directory is read-only. Bug #HDFFV-4342 (JKM 2011/4/12)
- Updated some HDF5 tools to standardize the option name as
'--enable-error-stack' for printing HDF5 error stack messages. h5ls and
h5dump have been updated. For h5ls, this replaces "-e/--errors" option,
which is deprecated. For h5dump, this is a new option. Bug #2182
(JKM 2011/3/30)
- Fixed the h5diff --use-system-epsilon option. The formula used in the
calculation was changed from ( |a - b| / b ) to ( |a - b| ).
This was done to improve performance. Bug #2184 (JKM 2011/3/24)
- Fixed output for H5T_REFERENCE in h5dump. According to the BNF document
the output of a H5T_REFERENCE should be followed by the type;
<reference> ::= H5T_REFERENCE { <ref_type> }
<ref_type> ::= H5T_STD_REF_OBJECT | H5T_STD_REF_DSETREG
Previously this was only displayed if the -R option was used.
Bug #1725 (ADB 2011/3/28)
- Fixed two h5diff issues. 1) h5diff compared attributes correctly only
when two objects had the same number of attributes and the attribute
names were identical. 2) h5diff did not display useful information about
attribute differences. Bug #2121 (JKM 2011/3/17)
- Fixed a memory leak in h5diff that occurred when accessing symbolic links
with the --follow-symlink option. Bug #2214 (JKM 2011/3/18)
- Fixed a memory leak in h5diff that occurred when accessing variable length
string data. Bug #2216 (JKM 2011/3/18)
- Fixed a memory leak in h5diff that occurred when accessing symbolic links
with the --follow-symlink option. Bug #2214 (JKM 2011/3/18)
- Fixed and improved the help page for h5ls -a, --address option.
Bug #1904 (JKM 2011/3/11)
- Fixed h5copy to enable copying an object into the same HDF5 file.
Previously h5copy displayed an error message when the target file
was the same as the source file. (XCAO 2011/3/8)
- Fixed an h5dump problem that caused the tool to skip some data elements
in large datasets with a large array datatype on Windows. This issue
arose only on Windows due to the different return behavior of the
_vsnprintf() function. Bug #2161 (JKM 2011/3/3)
- Fixed h5dump which was skipping some array indices in large datasets
with a relatively large array datatype. The interval of skipped indices
varied according to the size of the array. Bug #2092 (JKM 2011/2/15)
- Fixed h5diff which was segfaulting when comparing compound datasets
with a combination of fixed-length string datatypes and variable-length
string datatypes in certain orders. Bug #2089 (JKM 2010/12/28)
- Improved h5diff performance. 1) Now use HDmemcmp() before comparing two
elements. 2) Replace expensive H5Tequals() calls. 3) Retrieve datatype
information at dataset level, not at each element level for compound
datasets. ??????? Bug #???? (JKM 2010/12?/?? probably) ??????? ????????????????????????????????????????????????
- Fixed h5ls to display nested compound types with curly brackets
when -S (--simple) option is used with -l (--label), so it shows
which members (in curly brackets) belong to which nested compound type,
making the output clearer. Bug #1979 (JKM 2010/11/09)
- Fixed h5diff to handle variable-length strings in a compound dataset
and variable-length string arrays in a compound dataset correctly.
Garbage values were previously displayed when h5diff compared multiple
variable-length strings in a compound type dataset.
Bug #1989 (JKM 2010/10/28)
- Fixed h5copy to fail gracefully when copying an object to a non-
existing group without the -p option. Bug #2040 (JKM 2010/10/18)

Known Problems
==============
* The --with-mpe configure option does not work with Mpich2. AKC - 2011/03/10
* If parallel gmake (e.g., gmake -j 4) is used, the "gmake clean" command
sometimes fails in the perform directory due to the attempt to remove the
executable of h5perf or h5perf_serial by two "parallel" commands. This error
has no consequence on the functionality of the HDF5 library or install. It
is fixed in the next release. AKC - 2011/01/25 ??????? 4.18.2011. sent question to albert re: has this been fixed in 1.8.7?????????????????????????
* While working on the 1.8.6 release of HDF5, a bug was discovered that can
occur when reading from a dataset in parallel shortly after it has been
written to collectively. The issue was exposed by a new test in the parallel
HDF5 test suite, but had existed before that. We believe the problem lies with
certain MPI implementations and/or file systems.
We have provided a pure MPI test program, as well as a standalone HDF5
program, that can be used to determine if this is an issue on your system.
They should be run across multiple nodes with a varying number of processes.
These programs can be found at:
http://www.hdfgroup.org/ftp/HDF5/examples/known_problems/
* The AIX --enable-shared does not quite work. It can produce a shared library
but there cannot be more than one shared libraries that are interlinking with
each other. This means only the low-level C APIs can work. The high-level APIs
will not work which is not very useful. We hope to have a solution in the next
release. (AKC - 2010/10/15) ??????? 4.18.2011. sent question to albert re: has this been fixed in 1.8.7?????????????????????????
* The library's test dt_arith.c showed a compiler's rounding problem on
Cygwin when converting from unsigned long long to long double. The
library's own conversion works fine. We defined a macro for Cygwin to
skip this test until we can solve the problem. Please see bug #1813.
SLU - 2010/5/5
* All the VFL drivers aren't backward compatible. In H5FDpublic.h, the
structure H5FD_class_t changed in 1.8. There is new parameter added to
get_eoa and set_eoa callback functions. A new callback function
get_type_map was added in. The public function H5FDrealloc was taken
out in 1.8. The problem only happens when users define their own driver
for 1.6 and try to plug in 1.8 library. Because there's only one user
complaining about it, we (Elena, Quincey, and I) decided to leave it as
it is (see bug report #1279). Quincey will make a plan for 1.10.
SLU - 2010/2/2
* MinGW has a missing libstdc++.dll.a library file and will not successfully link
C++ applications/tests. Do not use the enable-cxx configure option. Read all of
the INSTALL_MINGW.txt file for all restrictions. ADB - 2009/11/11
* The PathScale MPI implementation, accessing a Panasas file system, would
cause H5Fcreate() with H5F_ACC_EXCL to fail even when the file does not
exist. This is due to the MPI_File_open() call failing if the mode has
the MPI_MODE_EXCL bit set. (See bug 1468 for details.) AKC - 2009/8/11
* Parallel tests failed with 16 processes with data inconsistency at testphdf5
/ dataset_readAll. Parallel tests also failed with 32 and 64 processes with
collective abort of all ranks at t_posix_compliant / allwrite_allread_blocks
with MPI IO. CMC - 2009/04/28
* For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh and
tools/h5copy/testh5copy.sh will fail some of its sub-tests. These sub-tests
are expected to fail and should exit with a non-zero code but the yod
command does not propagate the exit code of the executables. Yod always
returns 0 if it can launch the executable. The test suite shell expects
a non-zero for this particular test, therefore it concludes the test has
failed when it receives 0 from yod. Skip all the "failing" test for now
by changing them as following.
* The STDIO VFD does not work on some architectures, possibly due to 32/64
bit or large file issues. The basic STDIO VFD test is known to fail on
64-bit SunOS 5.10 on SPARC when built with -m64 and 32-bit OS X/Darwin
10.7.0. The STDIO VFD test has been disabled while we investigate and
a fix should appear in 1.8.8.

* For Red Storm, a Cray XT3 system, the yod command sometimes gives the
message, "yod allocation delayed for node recovery". This interferes with
test suites that do not expect to see this message. See the section of "Red
Storm" in file INSTALL_parallel for a way to deal with this problem.
AKC - 2008/05/28
* On an Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers,
use -mp -O1 compilation flags to build the libraries. A higher level of
optimization causes failures in several HDF5 library tests.
* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and
the application asks to do collective IO, we have found that when using 4
processors, a simple collective write will sometimes be hung. This can be
verified with t_mpi test under testpar.
* A dataset created or rewritten with a v1.6.3 library or after cannot be read
with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
There was a bug in the calculation of the Fletcher32 checksum in the
library before v1.6.3; the checksum value was not consistent between big-
endian and little-endian systems. This bug was fixed in Release 1.6.3.
However, after fixing the bug, the checksum value was no longer the same as
before on little-endian system. Library releases after 1.6.4 can still read
datasets created or rewritten with an HDF5 library of v1.6.2 or before.
SLU - 2005/6/30
* 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",
but HDF5 does not use sockets. This failure is due to problems with the
poe command trying to set up the debug socket. To resolve this problem,
check to see whether there are many old /tmp/s.pedb.* files staying around.
These are sockets used by the poe command and left behind due to failed
commands. First, ask your system administrator to clean them out.
Lastly, request IBM to provide a means to run poe without the debug socket.
* The --enable-static-exec configure flag will only statically link libraries
if the static version of that library is present. If only the shared version
of a library exists (i.e., most system libraries on Solaris, AIX, and Mac,
for example, only have shared versions), the flag should still result in a
successful compilation, but note that the installed executables will not be
fully static. Thus, the only guarantee on these systems is that the
executable is statically linked with just the HDF5 library.
* There is also a configure error on Altix machines that incorrectly reports
when a version of Szip without an encoder is being used.
* On cobalt, an SGI Altix SMP ia64 system, Intel compiler version 10.1 (which
is the default on that system) does not work properly and results in
failures during make check (in a static build) and make installcheck (during
a shared build). This appears to be a compiler optimization problem.
Reducing optimization by setting CFLAGS to -O1 or below resolves the issue.
Alternatively, using a newer version of the compiler (11.0) also works as
intended. MAM - 2010/06/01
