Jonathan Kim bf558b6fbf [svn-r20350] Purpose: 
Fixed CHICAGO: Bug 2121 - h5diff - incorrect and lack of output for the 
    different set of attributes (different number and names)

Description:
    Merged from HDF5 trunk r20334.
    This is related to previous checkin r20299.
    Add help page update for verbose option level feature, which displays 
    useful information about attribute difference with -v1, --verbose=1 -v2 
    or --verbose=2 option.

     
Tested:

and HISTORY-1_8.txt in the release_docs/ directory of the HDF5 source.
Links to the HDF5 1.8.7 source code, documentation, and additional materials
can be found on the HDF5 web page at:
http://www.hdfgroup.org/products/hdf5/
The HDF5 1.8.7 release can be obtained from:
http://www.hdfgroup.org/HDF5/release/obtain5.html
User documentation for 1.8.7 can be accessed directly at this location:
http://www.hdfgroup.org/HDF5/doc/
New features in the HDF5-1.8.x release series, including brief general
descriptions of some new and modified APIs, are described in the "What's New
in 1.8.0?" document:
http://www.hdfgroup.org/HDF5/doc/ADGuide/WhatsNew180.html
All new and modified APIs are listed in detail in the "HDF5 Software Changes
from Release to Release" document, in the section "Release 1.8.7 (current
release) versus Release 1.8.6":

- 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
-------------
- 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 H5Frelease_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 level for -v (verbose) option. The new levels are
1 and 2. So -v1 and -v2 can be specified to view more
information about 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
-------------
- None
Library
-------
- 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). I have fixed it. It is 1 (one) now.
(SLU - 2011/2/18)
Parallel Library
----------------
- None
Tools
-----
- Fix h5diff issues for #1: h5diff compared attributes correctly only
when two objects have the same number of attributes and attribute
names are identical, #2: didn't display useful information about
attribute difference. Bug#2121 (JKM 2011/3/17)
- Fixed memory leak for h5diff when accessing symbolic links with
--follow-symlink option. Bug#2214 (JKM 2011/3/18)
- Fixed memory leak for h5diff when access variable length string
data. Bug#2216 (JKM 2011/3/18)
- Fixed memory leak for h5diff when accessing symbolic links with
--follow-symlink option. Bug#2214 (JKM 2011/3/18)
- Fixed and improved help page for -a option of h5ls.
Bug#1904 (JKM 2011/3/11)
- Fixed h5copy to be able to copy any object into the same HDF5 file.
Previously h5copy displayed error message when target file is same
as source file. (XCAO 2011/3/8)
- Fixed h5dump for skipping some values for long array type dataset on
Windows. This issue only occurred on Windows due to the different
return behavior from _vsnprintf() funtion. Bug#2161 (JKM 2011/3/3)
- Fixed h5dump for skipping array indices every certain number
when the array type dataset is relatively big. The certain number
varies according to the size of array. Bug#2092 (JKM 2011/2/15).
- Fixed h5diff for the segfault when compares compound datasets
with combination of fixed length string types and vlen string types
in certain orders. bug#2089 (JKM 2010/12/28)
- Improve h5diff performance. 1) use HDmemcmp() before comparing each
elements. 2) replace expensive H5Tequals() calls 3) retrieve datatype
information at dataset level not each element level for compound
datasets
- Fixed h5ls to display nested compound type with curly bracket
when -S (--simple) option is used with -l (--label), so it shows
which member (in curly bracket) belong to which nested compound type
and make the output make sense. bug#1979 (JKM 2010/11/09)
- Fixed h5diff to handle variable-length strings in a compound dataset
correctly. (also variable-length string array in a compound dataset)
Garbage values were 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 object to non-exist
group without -p option. Bug#2040 (JKM 2010/10/18)

Known Problems
==============
* --with-mpe configure option does not work with Mpich2. AKC - 2011/03/10)
* examples/run-all-ex.sh does not work on Cygwin. (NAF - 2011/02/11)
* 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
* 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 filesystems.
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 shared library
but there cannot be more than one shared libraries that interlinking with
each other. That means only C-API without High-level can work. Not very
usefule. We hope to have a solution in the next release. (AKC - 2010/10/15)
* 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 is not
existing. This is due to the MPI_File_open() call failing if the amode 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.

==================================================
AKC - 2008/11/10
* 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 seeing 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 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.

* 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
