For more details, see the files HISTORY-1_0-1_8_0_rc3.txt 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": http://www.hdfgroup.org/HDF5/doc/ADGuide/Changes.html If you have any questions or comments, please send them to the HDF Help Desk: help@hdfgroup.org 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 ------- - The library allows the dimension size of a dataspace to be zero. In the past, the library would allow this only if the maximal dimension size was unlimited. Now there is no such restriction, but no data can be written to this kind of dataset. (SLU - 2011/4/20) - We added two new macros, H5_VERSION_GE and H5_VERSION_LE, to let users compare certain version numbers with the library being used. (SLU - 2011/4/20) - 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 Metrowerks compilers, bracketed by __MWERKS__). Metrowerks 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) High-Level APIs --------------- - Fortran LT make datasets routines (H5LTmake_dataset_f, h5ltmake_dataset_int_f, h5ltmake_dataset_float_f, h5ltmake_dataset_double_f) and LT read datasets routines (h5ltread_dataset_f,h5ltread_dataset_int_f, h5ltread_dataset_float_f, 5ltread_dataset_double_f) can now handle 4-dimensional to 7-dimensional rank datasets. HDFFV-1217 (MSB-2011/4/24/2011) F90 API ------- - None C++ API ------- - None 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 ------------- - Shared C++ and HL libraries on AIX should now be working correctly. Note that Fortran shared libraries are still not working on AIX. (See the Known Problems section, below). (MAM - 2011/4/20) - 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. (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) - Fixed h5dump displaying incorrect values for H5T_STD_I8BE type data in attribute on Big-Endian machine. H5T_STD_I8BE is unsigned 8bit type, so h5dump is supposed to display -2 instead of 254. It worked correctly on Little-Endian system , but not on Big-Endian system. Bug #HDFFV-4358 (JKM 04/08/2011) - 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; ::= H5T_REFERENCE { } ::= 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 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. HDFFV-7516 (JKM 2011/4/18) - 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) F90 API ------ - None C++ API ------ - None High-Level APIs: ------ - None Fortran High-Level APIs: ------ - h5tbmake_table_f: Fixed error in passing an array of characters with different length field names. - h5tget_field_info_f: Fixed error with packing the C strings into a Fortran array of strings. Added optional argument called 'maxlen_out' which returns the maximum string character length in a field name element.

Compiler versions for each platform are listed in the preceding "Platforms Tested" table. Known Problems ============== * After the shared library support was fixed for some bugs, it was discovered that "make prefix=XXX install" no longer works for shared libraries. It still works correctly for static libraries. Therefore, if you want to install the HDF5 shared libraries in a location such as /usr/local/hdf5, you need to specify the location via the --prefix option during configure time. E.g, ./configure --prefix=/usr/local/hdf5 ... (AKC - 2011/05/07 HDFFV-7583) * The parallel test, t_shapesame, in testpar/, may run for a long time and may be terminated by the alarm signal. If that happens, one can increase the alarm seconds (default is 1200 seconds = 20 minutes) by setting the environment variable, $HDF5_ALARM_SECONDS, to a larger value such as 3600 (60 minutes). Note that the t_shapesame test may fail in some systems (see the "While working on the 1.8.6 release..." problem below). If it does, it will waste more time if $HDF5_ALARM_SECONDS is set to a larger value. (AKC - 2011/05/07) * The C++ and FORTRAN bindings are not currently working on FreeBSD. (QAK - 2011/04/26) * Shared Fortran libraries are not quite working on AIX. While they are generated when --enable-shared is specified, the fortran and hl/fortran tests fail. We are looking into the issue. HL and C++ shared libraries should now be working as intended, however. (MAM - 2011/04/20) * 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 * 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 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.

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 * h5diff will not report enum value differences when one or both of the values is not a valid enumeration value. The source of this bug has been identified and it will be fixed in 1.8.8. DER - 2011/04/27 %%%%1.8.6%%%% HDF5 version 1.8.6 released on Mon Feb 14 10:26:30 CST 2011 ================================================================================ INTRODUCTION ============ This document describes the differences between HDF5-1.8.5 and HDF5 1.8.6, and contains information on the platforms tested and known problems in HDF5-1.8.6. For more details, see the files HISTORY-1_0-1_8_0_rc3.txt and HISTORY-1_8.txt in the release_docs/ directory of the HDF5 source. Links to the HDF5 1.8.6 source code, documentation, and additional materials can be found on the HDF5 web page at: http://www.hdfgroup.org/products/hdf5/ The HDF5 1.8.6 release can be obtained from: http://www.hdfgroup.org/HDF5/release/obtain5.html User documentation for 1.8.6 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 1.8.6 (current release) versus Release 1.8.5": http://www.hdfgroup.org/HDF5/doc/ADGuide/Changes.html If you have any questions or comments, please send them to the HDF Help Desk: help@hdfgroup.org CONTENTS ======== - New Features - Support for New Platforms, Languages, and Compilers - Bug Fixes since HDF5-1.8.5 - Platforms Tested - Supported Configuration Features Summary - Known Problems New Features ============ Configuration ------------- - CMake: Improved CPack packaging, added parallel commands, improved configuration options (better similarity to configure), added more tests, better support for use in external cmake projects. (ADB - 2010/10/07) - The default configuration setting for official releases is --enable-production. For unofficial releases, the default configuration setting has been --disable-production. (AKC - 2010/05/28) Library ------- - Added support for thread safety on Windows using the Windows threads library. Use the HDF5_ENABLE_THREADSAFE option in CMake on a Windows platform to enable this functionality. This is supported on Windows Vista and newer Windows operating systems. (MAM - 2010/09/10) - H5Tset_order and H5Tget_order now support all datatypes. A new byte order, H5T_ORDER_MIXED, has been added specifically for a compound datatype and its derived type. (SLU - 2010/8/23) - Improved performance of metadata I/O by changing the default algorithm to perform I/O from all processes (instead of just process 0) when using parallel I/O drivers. (QAK - 2010/07/19) - Improved performance of I/O on datasets with the same shape, but different rank. (QAK - 2010/07/19) - Improved performance of the chunk cache by avoiding unnecessary b-tree lookups of chunks already in cache. (NAF - 2010/06/15) Parallel Library ---------------- - None Tools ----- - h5diff: Added a new flag: --exclude-path. The specified path to an object will be excluded when comparing two files or two groups. If a group is specified to be excluded, all member objects of that group will be excluded. (JKM - 2010/09/16). - h5ls: Added a new flag: --no-dangling-links. See --help output for details. (JKM - 2010/06/15) - h5ls: Added a new flag --follow-symlinks. See --help output for details. (JKM - 2010/05/25) High-Level APIs --------------- - None F90 API ------- - None C++ API ------- - None Support for New Platforms, Languages, and Compilers =================================================== - Sun C and C++ 5.10 and Sun Fortran 95 8.4. - Mac OS X 10.6.4 with gcc 4.2.1 and gfortran 4.6 Bug Fixes since HDF5-1.8.5 ========================== Configuration ------------- - The default number of MPI processes for testing purposes has been changed from 3 to 6. (AKC - 2010/11/11) - Some tests in tools/h5repack may fail in AIX systems when -q32 mode is used. The error is caused by not requesting enough memory in default. Added "env LDR_CNTRL=MAXDATA=0x20000000@DSA" into the $RUNSERIAL and $RUNPARALLE in the AIX config file so that executables are tested with more memory. (AKC - 2010/11/11) - Removed recognition of the parallel compilers of LAM(hcc) and ChMPIon(cmpicc) since we have no access to these two MPI implementations and cannot verify their correctness. (AKC - 2010/07/14 - Bug 1921) - PHDF5 was changed to use "mpiexec" instead of mpirun as the default MPI applications startup command as defined in the MPI-2 definition, section 4.1. (AKC - 2010/06/11 - Bug 1921) Library ------- - Fixed a bug that caused big endian machines to generate corrupt files when using the scale-offset filter with floating point data or fill values. Note that such datasets will no longer be readable by any by any machine after this patch. (NAF - 2010/02/02 - Bug 2131) - Retrieving a link's name by index in the case where the link is external and the file that the link refers to doesn't exist will now fail gracefully rather than cause a segmentation fault. (MAM - 2010/11/17) - Modified metadata accumulator to better track accumulated dirty metadata in an effort to reduce unnecessary I/O in certain situations and to fix some other corner cases which were prone to error. (MAM - 2010/10/15) - Added a new set of unit tests that are run during 'make check' to verify the behavior of the metadata accumulator. (MAM - 2010/10/15) - Modified library to always cache symbol table information. Libraries from version 1.6.3 and earler have a bug which causes them to require this information for some operations. (NAF - 2010/09/21 - Bug 1864) - Fixed a bug where the library could generate an assertion/core dump when a file that had been created with H5Pset_libver_bounds(fapl, H5F_LIBVER_LATEST, H5F_LIBVER_LATEST) but didn't have a superblock extension was later reopened. (QAK - 2010/09/16 - Bug 1968) - Fixed a bug that could occur when getting information for a new-style group that was previously opened through a file handle that was later closed. (NAF - 2010/09/15) - Added define check in H5public.h if stdint.h is supported by the C++ compiler. This define is only available on Windows with VS2010 and using CMake to build the library. (ADB - 2010/09/13 - Bug 1938) - When a mandatory filter failed to write data chunks, the dataset couldn't close (bug 1260). The fix releases all resources and closes the dataset but returns a failure. (SLU - 2010/09/08) - H5Eset_current_stack now also closes the error stack set as the default. This is to avoid a potential problem. (SLU - 2010/09/07 - Bug 1799) - Corrected situation where 1-D chunked dataset could get created by an application without calling H5Pset_chunk(). H5Pset_chunk is now required for creating all chunked datasets. (QAK - 2010/09/02) - Fixed many memory issues that valgrind exposed. (QAK - 2010/08/24) - Fixed the bug in the filter's public CAN_APPLY function. The return value should be htri_t not herr_t. (SLU - 2010/08/05 - Bug 1239) - Fixed the STDIO VFD to use fseeko64 instead of fseek64 for 64-bit I/O support. (AKC - 2010/7/30) - Fixed a bug in the direct I/O driver that could render files with certain kinds of unaligned data unreadable or corrupt them. (NAF - 2010/07/28) - valgrind reported an error of copying data to itself when a new attribute is written. Fixed by taking out the memcpy step in the attribute code. (SLU - 2010/07/28 - Bug 1956) - Corrected various issues in the MPI datatype creation code which could cause resource leaks or incorrect behavior (and may improve the performance as well). (QAK - 2010/07/19) - Fixed a bug that could cause file corruption when using non-default sizes of addresses and/or lengths. This bug could also cause uncorrupted files with this property to be unreadable. This bug was introduced in 1.8.5. (NAF - 2010/07/16 - Bug 1951) Parallel Library ---------------- - None Tools ----- - Fixed h5diff to compare member objects and groups recursively when two files or groups are compared. (JKM - 2010/9/16 - Bug 1975) - Fixed h5repack to be able to convert a dataset to COMPACT layout. (JKM - 2010/09/15 - Bug 1896) - Changed h5ls to not interpret special characters in object or attribute names for output. (JKM - 2010/06/28 - Bug 1784) - Revised the order of arguments for h5cc, h5fc, h5c++, h5pcc and h5pfc. CPPFLAGS, CFLAGS, LDFLAGS, and LIBS have been duplicated with an H5BLD_ prefix to put the flags and paths from the hdf5 build in the correct places and allow the script user to add entries in CPPFLAGS, CFLAGS, LDFLAGS, and LIBS that will take precedence over those from the hdf5 build. The user can make these entries persistent by editing CFLAGSBASE, CPPFLAGSBASE, LDFLAGSBASE, and LIBSBASE near the top of the script or temporary by setting HDF5_CFLAGS, HDF5_CPPFLAGS, HDF5_LDFLAGS, or HDF5_LIBS in the environment. The new order of arguments in these scripts is $CLINKER $H5BLD_CPPFLAGS $CPPFLAGS $H5BLD_CFLAGS $CFLAGS $LDFLAGS $clibpath $link_objs $LIBS $link_args $shared_link.

Compiler versions for each platform are listed in the preceding "Platforms Tested" table. Known Problems ============== * examples/run-all-ex.sh does not work on Cygwin. (NAF - 2011/02/11) * Parallel test, t_shapesame in testpar, is rather unstable as it continues to have occasional errors in AIX and quite often in NCSA Abe. It is being built but it is not run automatically in the "make check" command. One would have to run it by hand to see if it works in a particular machine. AKC - 2011/01/28 * Although OpenVMS Alpha is supported, there are several problems with the C test suite - getname.c, lheap.c, lheap.c, mtime.c, and stab.c. The test suite for h5diff also fails. These failures are from the tests, not the library. We have fixed these failures. But it's too late to put the fixes into this release. If you install the 1.8.6 library, it should still work despite of these test failures. If you want the working copy without any test failure, you can request it from us. SLU - 2011/01/26 * 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 h5diff tool can display garbage values when variable-length strings in a compound type dataset are compared. This also occurs with variable-length string arrays in a compound type dataset. See bug #1989. This will be fixed in the next release. JKM - 2010/11/05 * The AIX --enable-shared setting does not quite work. It can produce a shared library, but there cannot be more than one shared library that is interlinked. This means that 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) * H5Eset_auto can cause a seg fault for a library API call if the application compiles with -DH5_USE_16_API (see bug 1707). It will be fixed in the next release. SLU - 2010/10/5 * The library's test dt_arith.c showed a compiler's rounding problem on Cygwin when converting an unsigned long long to a 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 backwardly compatible. In H5FDpublic.h, the structure H5FD_class_t changed in 1.8. A new parameter was added to the get_eoa and set_eoa callback functions, and a new callback function get_type_map was added. 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 a 1.8 library. This will be fixed in 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 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 their 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. To skip all the "failing" tests for now, change them as shown below. ======== Original tools/h5ls/testh5ls.sh ========= TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 ======== Change to =============================== echo SKIP TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 ================================================== ======== Original tools/h5copy/testh5copy.sh ========= TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested H5LSTEST $FILEOUT ======== Change to =============================== echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested echo SKIP H5LSTEST $FILEOUT ================================================== 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 to see this message. See the "Red Storm" section 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 the -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 on a system using four processors, if more than two processes contribute no I/O and the application asks to do collective I/O, we have found that a simple collective write will sometimes hang. This can be verified with the t_mpi test under testpar. * A dataset created or rewritten with a v1.6.3 or later library cannot be read with the v1.6.2 or earlier library 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 earlier. 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'. To work around this, 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 any old /tmp/s.pedb.* files around. These are sockets used by the poe command and left behind if the command failed at some point. To resolve this, ask your system administrator to remove the old/tmp/s.pedb.* files, and then ask 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. * On an SGI Altix SMP ia64 system, the Intel compiler version 10.1 (which is the default on that system) does not work properly and results in failures during the make check (in a static build) and the make installcheck (in a shared build). This appears to be a compiler optimization problem. Reducing the optimization by setting CFLAGS to -O1 or below resolves the issue. Using a newer version of the compiler (11.0) avoids the issue. MAM - 2010/06/01 * On solaris systems, when running the examples with the scripts installed in .../share/hdf5_examples, two of the c tests, h5_extlink and h5_elink_unix2win may fail or generate HDF5 errors because the script commands in c/run-c-ex.sh fail to create test directories red, blue, and u2w. Moving the '!' in lines 67, 70, 73 of run-c-ex.sh will fix the problem. For example the script command "if ! test -d red; then" will work on solaris if changed to "if test ! -d red; then". %%%%1.8.5%%%% HDF5 version 1.8.5 released on Fri Jun 4 13:27:31 CDT 2010 ================================================================================ INTRODUCTION ============ This document describes the differences between HDF5-1.8.4 and HDF5 1.8.5, and contains information on the platforms tested and known problems in HDF5-1.8.5. For more details, see the files HISTORY-1_0-1_8_0_rc3.txt and HISTORY-1_8.txt in the release_docs/ directory of the HDF5 source. Links to the HDF5 1.8.5 source code, documentation, and additional materials can be found on the HDF5 web page at: http://www.hdfgroup.org/products/hdf5/ The HDF5 1.8.5 release can be obtained from: http://www.hdfgroup.org/HDF5/release/obtain5.html User documentation for 1.8.5 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 1.8.5 (current release) versus Release 1.8.4": http://www.hdfgroup.org/HDF5/doc/ADGuide/Changes.html If you have any questions or comments, please send them to the HDF Help Desk: help@hdfgroup.org CONTENTS ======== - New Features - Support for New Platforms, Languages, and Compilers - Bug Fixes since HDF5-1.8.4 - Platforms Tested - Supported Configuration Features Summary - Known Problems New Features ============ Configuration ------------- - CMake Early Access: This release adds support for building HDF5 using the CMake system. Initial work has targeted Windows, but other platforms can be used. See the CMake.TXT file for more information. Version 2.8.1 of CMake is required. - Configure now adds appropriate defines for supporting large (64-bit) files on all systems, where supported, by default, instead of only Linux. This large file support is controllable with the --enable-largefile configure option. The Linux-specific --enable-linux-lfs option has been deprecated in favor of this new option. Please note that specifying --disable-large does NOT attempt to "turn off" largefile support if it is natively supported by the compiler, but rather just disables configure from actively trying to add any additional compiler flags. (MAM - 2010/05/05 - Bug # 1772/1434) - Fixed an signal handling mask error in H5detect that might result in SIGBUS or SIGSEGV failures in some platforms such as Linux on Sparc. (AKC - 2010/4/28 - Bug # 1764) - Fixed various "strict aliasing" problems, allowing higher levels of compiler optimization (in particular, allowing '-O3' to work with recent versions of GCC). (QAK - 2010/04/26) - Upgraded versions of autotools used to generate configuration suite. We now use Automake 1.11.1, Autoconf 2.65, and Libtool 2.2.6b. (MAM - 2010/04/15) - Added the xlc-* and mpcc_r-* BASENAME patterns to be recognized as IBM compilers so that the IBM compiler options can be added properly. This allows non-system-default compiler command names (e.g. xlc-m.n.k.l) be recognized. (AKC - 2009/11/26) Library ------- - Performance is substantially improved when extending a dataset with early allocation. (NAF - 2010/03/24 - Bug # 1637) - Added support for filtering densely stored groups. Many of the API functions related to filters have been extended to support dense groups as well as datasets. Pipeline messages can now be stored in a group's object header. (NAF/QAK - 2009/11/3) Parallel Library ---------------- - None Tools ----- - h5dump: Added the new packed bits feature which prints packed bits stored in an integer dataset. (AKC/ADB - 2010/5/7) - h5diff: Fixed incorrect behavior (hang) in parallel mode when specifying invalid options (ex: -v and -q). (JKM - 2010/02/17) - h5diff: Added new flag --no-dangling-links (see --help for details). (JKM - 2010/02/10) - h5diff: Added new flag --follow-symlinks (see --help for details). (JKM - 2010/01/25) - h5diff: Added a fix to correct the display of garbage values when displaying big-endian data on a little-endian machine. (JKM - 2009/11/20) High-Level APIs --------------- - None F90 API ------- - None C++ API ------- - New member functions + Overloaded CommonFG::getObjnameByIdx to take char* for name. + Overloaded CommonFG::getObjTypeByIdx to return type name as a char*. (BMR - 2010/05/10) + Added DataSet::getInMemDataSize() to simplify getting the dataset's data size in memory. (BMR - 2009/07/26) Support for New Platforms, Languages, and Compilers =================================================== - AIX 6.1 has been added. (AKC - 2010/1/4) Bug Fixes since HDF5-1.8.4 ========================== Configuration ------------- - Fixed various "strict aliasing" problems, allowing higher levels of compiler optimization (in particular, allowing '-O3' to work with recent versions of GCC). (QAK - 2010/04/26) Library ------- - Fixed a file corruption bug that could happen when shrinking a compressed dataset. (NAF - 2010/05/20) - Fixed some memory leaks in VL datatype conversion when strings are used as fill values. (MAM - 2010/05/12 - Bug # 1826) - Fixed an H5Rcreate failure when passing in a -1 for the dataspace identifier. (ADB - 2010/4/28) - Fixed a bug when copying objects with NULL references with the H5O_COPY_EXPAND_REFERENCE_FLAG flag set. (NAF - 2010/04/08 - Bug # 1815) - Added a mechanism to the H5I interface to save returned object identifier structures for immediate re-use if needed. This addresses a potential performance issue by delaying the case when the next identifier to be registered has grown so large that it wraps around and needs to be checked to see whether it is available for distribution. (MAM - 2010/03/15 - Bug # 1730) - Files can now be concurrently opened more than once using the core file driver, as long as the backing store is used. (NAF - 2010/03/09) - Added support for H5O_COPY_EXPAND_EXT_LINK_FLAG to H5Ocopy. External links will now be expanded if this flag is set. (NAF - 2010/03/05 - Bug # 1733) - Fixed a bug where the library, when traversing an external link, would reopen the source file if nothing else worked. (NAF - 2010/03/05) - Fixed a bug where fractal heap identifiers for attributes and shared object header messages could be incorrectly encoded in the file for files created on big-endian platforms. Please see http://www.hdfgroup.org/HDF5/release/known_problems if you suspect you have a file with this problem. (QAK - 2010/02/23 - Bug # 1755) - Fixed an intermittent bug in the b-tree code which could be triggered by expanding and shrinking chunked datasets in certain ways. (NAF - 2010/02/16) - H5Tdetect_class said a VL string is a string type. But when it's in a compound type, it said it's a VL type. THis has been fixed to be consistent; it now always returns a string type. (SLU - 2009/12/10 - Bug # 1584) - Allow "child" files from external links to be correctly located when relative to a "parent" file that is opened through a symbolic link. (QAK - 2009/12/01) Parallel Library ---------------- - Parallel mode in AIX will fail some of the testcheck_version.sh tests where it treats "exit(134) the same as if process 0 had received an abort signal. Fixed. (AKC - 2009/11/3) Tools ----- - Fixed h5ls to return exit code 1 (error) when a non-existent file is specified. (JKM - 2010/04/27 - Bug # 1793) - Fixed h5copy failure when copying a dangling link that is specified directly. (JKM - 2010/04/22 - Bug # 1817) - Fixed an h5repack failure that lost attributes from a dataset of reference type. (JKM - 2010/3/25 - Bug # 1726) - Fixed h5repack error that set NULL for object reference values for datasets, groups, or named datatypes. (JKM - 2010/03/19 - Bug # 1814) F90 API ------ - None C++ API ------ - The constructor PropList::PropList(id) was fixed to act properly according to the nature of 'id'. When 'id' is a property class identifier, a new property list will be created. When 'id' is a property list identifier, a copy of the property list will be made. (BMR - 2010/5/9) - The parameters 'size' and 'bufsize' in CommonFG::getLinkval and CommonFG::getComment, respectively, now have default values for the user's convenience. (BMR - 2009/10/23) - NULL pointer accessing was fixed. (BMR - 2009/10/05 - Bug # 1061) - Read/write methods of DataSet and Attribute classes were fixed to handle string correctly. (BMR - 2009/07/26) High-Level APIs: ------ - Fixed a bug in H5DSattach_scale, H5DSis_attached, and H5DSdetach_scale caused by using the H5Tget_native_type function to determine the native type for reading the REFERENCE_LIST attribute. This bug was exposed on Mac PPC. (EIP - 2010/05/22 - Bug # 1851) - Fixed a bug in the H5DSdetach_scale function when 0 bytes were allocated after the last reference to a dimension scale was removed from the list of references in a VL element of the DIMENSION_LIST attribute. Modified the function to comply with the specification: the DIMENSION_LIST attribute is now deleted when no dimension scales are left attached.

Known Problems ============== * The library's test dt_arith.c exposed a compiler's rounding problem on Cygwin when converting from unsigned long long to long double. The library's own conversion works correctly. A macro is defined 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 a new parameter added to get_eoa and set_eoa callback functions. A new callback function get_type_map was added. 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 it into a 1.8 library. This affects a very small number of users. (See bug report #1279.) 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 * Some tests in tools/h5repack may fail in AIX systems when -q32 mode is used. The error is due to insufficient memory requested. Request a large amount of runtime memory by setting the following environment variable for more memory. LDR_CNTRL=MAXDATA=0x20000000@DSA AKC - 2009/10/31 * 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 gcc v4.3 and v4.4, with production mode, if -O3 is used, H5Tinit.c would fail to compile. Actually bad H5Tinit.c is produced. If -O (same as -O1) is used, H5Tinit.c compiled okay but test/dt_arith would fail. When -O0 (no optimizatio) is used, H5Tinit.c compilete okay and all tests passed. Therefore, -O0 is imposed for v4.3 and v4.4 of gcc. AKC - 2009/04/20 * 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. ======== Original tools/h5ls/testh5ls.sh ========= TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 ======== Change to =============================== echo SKIP TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 ================================================== ======== Original tools/h5copy/testh5copy.sh ========= TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested H5LSTEST $FILEOUT ======== Change to =============================== echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested echo SKIP H5LSTEST $FILEOUT ================================================== 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. 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 FREE-BSD systems when shared libraries are disabled, make install fails in install-examples with the error '"Makefile", line 635: Need an operator'. When this error occurs removing or commenting out the line "export LD_LIBRARY_PATH=$(LL_PATH)" (line 635 in examples/Makefile) will allow make install to finish installing examples. The problem will be fixed in the next release. LRK - 2010/05/26 * 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 %%%%1.8.4%%%% HDF5 version 1.8.4 released on Tue Nov 10 15:33:14 CST 2009 ================================================================================ INTRODUCTION ============ This document describes the differences between HDF5-1.8.3 and HDF5 1.8.4, and contains information on the platforms tested and known problems in HDF5-1.8.4 For more details, see the files HISTORY-1_0-1_8_0_rc3.txt and HISTORY-1_8.txt in the release_docs/ directory of the HDF5 source. Links to the HDF5 1.8.4 source code, documentation, and additional materials can be found on the HDF5 web page at: http://www.hdfgroup.org/products/hdf5/ The HDF5 1.8.4 release can be obtained from: http://www.hdfgroup.org/HDF5/release/obtain5.html User documentation for 1.8.4 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 1.8.4 (current release) versus Release 1.8.3": http://www.hdfgroup.org/HDF5/doc/ADGuide/Changes.html If you have any questions or comments, please send them to the HDF Help Desk: help@hdfgroup.org CONTENTS ======== - New Features - Support for New Platforms, Languages, and Compilers - Bug Fixes since HDF5-1.8.3 - Platforms Tested - Supported Configuration Features Summary - Known Problems New Features ============ Configuration ------------- - Configuration suite now uses Automake 1.11 and Autoconf 2.64. MAM 2009/08/31. - Changed default Gnu fortran compiler from g95 to gfortran since gfortran is more likely installed with gcc now. -AKC 2009/07/19- Library ------- - The embedded library information is displayed by H5check_version() if a version mismatch is detected. Also changed H5check_version() to suppress the warning message totally if $HDF5_DISABLE_VERSION_CHECK is 2 or higher. (Old behavior treated 3 or higher the same as 1, that is print a warning and allows the program to continue. (AKC - 2009/9/28) - If a user does not care for the extra library information insert in the executables, he may turn it off by --disable-embedded-libinfo during configure. (AKC - 2009/9/15) Parallel Library ---------------- - None Tools ----- - h5diff: h5diff treats two INFINITY values different. Fixed by checking (value==expect) before call ABS(...) at h5diff_array.c. This will make that (INF==INF) is true (INF is treated as an number instead of NaN) (PC -- 2009/07/28) - h5diff: add option "--use-system-epsilon" to print difference if (|a-b| > EPSILON). Change default to use strict equality (PC -- 2009/09/12) High-Level APIs --------------- - None F90 API ------- - Added H5Oopen_by_addr_f MSB - 9/14/09 C++ API ------- - None Support for New Platforms, Languages, and Compilers =================================================== - PathScale compilers are recognized and can build the HDF5 library properly. AKC - 2009/7/28 - Bug Fixes since HDF5-1.8.3 ========================== Configuration ------------- - Removed the following config files, as we no longer support them: config/dec-osf*, config/hpux11.00, config/irix5.x, config/powerpc-ibm-aix4.x config/rs6000-ibm-aix5.x config/unicos* MAM - 2009/10/08 - Modified configure and make process to properly preserve user's CFLAGS (and company) environment variables. Build will now properly use automake's AM_CFLAGS for any compiler flags set by the configure process. Configure will no longer modify CFLAGS directly, nor will setting CFLAGS during make completely replace what configure has set up. MAM - 2009/10/08 - Support for TFLOPS, config/intel-osf1, is removed since the TFLOPS machine has long retired. AKC - 2009/10/06. - Added $(EXEEXT) extension to H5detect when it's executed in the src/Makefile to generate H5Tinit.c so it works correctly on platforms that require the full extension when running executables. MAM - 2009/10/01 - BZ #1613 - Configure will now set FC and CXX to "no" when fortran and c++ are not being compiled, respectively, so configure will not run some of the compiler tests for these languages when they are not being used. MAM - 2009/10/01 - The --enable-static-exec flag will now properly place the -static flag on the link line of all installed executables. This will force the executable to link with static libraries over shared libraries, provided the static libraries are available. MAM - 2009/08/31 - BZ #1583 - The PathScale compiler (v3.2) was mistaken as gcc v4.2.0 but it fails to recognize some gcc options. Fixed. (see bug 1301). AKC - 2009/7/28 - Library ------- - Fixed a bug where writing and deleting many global heap objects (i.e. variable length data) would render the file unreadable. Previously created files exhibiting this problem should now be readable. NAF - 2009/10/27 - 1483 - Fixed error in library's internal caching mechanisms which could cause an assertion failure (and attendent core dump) when encountering an unusually formatted file. (QAK - 2009/10/13) - Fixed incorrect return value for H5Pget_preserve. AKC - 2009/10/08 - 1628 - Fixed an assertion failure that occurred when H5Ocopy was called on a dataset using a vlen inside a compound. NAF - 2009/10/02 - 1597 - Fixed incorrect return value for H5Pget_filter_by_id1/2 in H5Ppublic.h. NAF - 2009/09/25 - 1620 - Fixed a bug where properties weren't being compared with the registered compare callback. NAF - 2009/09/25 - 1555 - Corrected problem where library would re-write the superblock in a file opened for R/W access, even when no changes were made to the file. (QAK - 2009/08/20, Bz#1473) - Fixed a bug where H5Pget_filter_by_id would succeed when called for a filter that wasn't present. NAF - 2009/06/25 - 1250 - Fixed an issue with committed compound datatypes containing a vlen. Also fixed memory leaks involving committed datatypes. NAF - 2009/06/10 - 1593 Parallel Library ---------------- - None Tools ----- - h5dump/h5ls display buffer resize fixed in tools library. ADB - 2009/7/21 - 1520 - perf_serial test added to Windows projects and check batch file. ADB - 2009/06/11 -1504 F90 API ------ - Fixed bug in h5lget_info_by_idx_f by adding missing arguments, consequently changing the API. New API is: SUBROUTINE h5lget_info_by_idx_f(loc_id, group_name, index_field, order, n, & link_type, f_corder_valid, corder, cset, address, val_size, hdferr, lapl_id) MSB - 2009/9/17 - 1652 - Corrected the values for the H5L_flags FORTRAN constants: H5L_LINK_ERROR_F, H5L_LINK_HARD_F, H5L_LINK_SOFT_F, H5L_LINK_EXTERNAL_F MSB - 2009-09-17 - 1653 - Added FORTRAN equivalent of C constant H5T_ORDER_NONE: H5T_ORDER_NONE_F MSB - 2009-9-24 - 1471 C++ API ------ - None High-Level APIs: ------ - Fixed a bug where the H5TB API would forget the order of fields when added out of offset order. NAF - 2009/10/27 - 1582 - H5DSis_attached failed to account for different platform types. Added a get native type call. ADB - 2009/9/29 - 1562 Fortran High-Level APIs: ------ - Lite: the h5ltread_dataset_string_f and h5ltget_attribute_string_f functions had memory problems with the g95 fortran compiler.

Known Problems ============== * Parallel mode in AIX will fail some of the testcheck_version.sh tests where it treats "exit(134) the same as if process 0 had received an abort signal. This is fixed and will be available in the next release. AKC - 2009/11/3 * Some tests in tools/h5repack may fail in AIX systems when -q32 mode is used. The error is due to insufficient memory requested. Request a large amount of runtime memory by setting the following environment variable for more memory. LDR_CNTRL=MAXDATA=0x20000000@DSA AKC - 2009/10/31 * 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 * There is a known issue in which HDF5 will change the timestamp on a file simply by opening it with read/write permissions, even if the file is not modified in any way. This is due to the way in which HDF5 manages the file superblock. A fix is currently underway and should be included in the 1.8.4 release of HDF5. MAM - 2009/04/28 * For gcc v4.3 and v4.4, with production mode, if -O3 is used, H5Tinit.c would fail to compile. Actually bad H5Tinit.c is produced. If -O (same as -O1) is used, H5Tinit.c compiled okay but test/dt_arith would fail. When -O0 (no optimizatio) is used, H5Tinit.c compilete okay and all tests passed. Therefore, -O0 is imposed for v4.3 and v4.4 of gcc. AKC - 2009/04/20 * 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.

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. 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. %%%%1.8.3%%%% HDF5 version 1.8.3 released on Mon May 4 09:21:00 CDT 2009 ================================================================================ INTRODUCTION ============ This document describes the differences between HDF5-1.8.2 and HDF5 1.8.3, and contains information on the platforms tested and known problems in HDF5-1.8.3. For more details, see the files HISTORY-1_0-1_8_0_rc3.txt and HISTORY-1_8.txt in the release_docs/ directory of the HDF5 source. Links to the HDF5 1.8.3 source code, documentation, and additional materials can be found on the HDF5 web page at: http://www.hdfgroup.org/products/hdf5/ The HDF5 1.8.3 release can be obtained from: http://www.hdfgroup.org/HDF5/release/obtain5.html User documentation for 1.8.3 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 1.8.3 (current release) versus Release 1.8.2": http://www.hdfgroup.org/HDF5/doc/ADGuide/Changes.html If you have any questions or comments, please send them to the HDF Help Desk: help@hdfgroup.org CONTENTS ======== - New Features - Support for New Platforms, Languages, and Compilers - Bug Fixes since HDF5-1.8.2 - Platforms Tested - Supported Configuration Features Summary - Known Problems New Features ============ Configuration ------------- - Added libtool version numbers to generated c++, fortran, and hl libraries. MAM 2009/04/19. - Regenerated Makefile.ins using Automake 1.10.2. MAM 2009/04/19. - Added a Make target of check-all-install to test the correctness of installing via the prefix= or $DESTDIR options. AKC - 2009/04/14 Library ------- - Embed the content of libhdf5.settings into the hdf5 executables so that an "orphaned" executables can display (via the Unix strings command, for example) the library settings used to build the executables. This is a prototype implementation. Improvement will be added in next release. AKC - 2009/04/20 - Separated "factory" free list class from block free lists. These free lists are dynamically created and manage blocks of a fixed size. H5set_free_list_limits() will use the same settings specified for block free lists for factory free lists. NAF - 2009/04/08 - Added support for dense attributes to H5Ocopy. XCao/NAF - 2009/01/29 - Added H5Pset_elink_cb and H5Pget_elink_cb functions to support a user-defined callback function for external link traversal. NAF - 2009/01/08 - Added H5Pset_elink_acc_flags and H5Pget_elink_acc_flags functions to allow the user to specify the file access flags used to open the target file of an external link. NAF - 2009/01/08 - Added H5Pset_chunk_cache() and H5Pget_chunk_cache() functions to allow individual rdcc configuration for each dataset. Added H5Dget_access_plist() function to retrieve a dataset access property list from a dataset. NAF - 2008/11/12 - Added H5Iis_valid() function to check if an id is valid without producing an error message. NAF - 2008/11/5 - Added code to maintain a min_clean_fraction in the metadata cache when in serial mode. MAM - 2009/01/9 Parallel Library ---------------- - Modified parallel tests to run with arbitrary number of processes. The modified tests are testphdf5 (parallel dataset access), t_chunk_alloc (chunk allocation), and t_posix_compliant (posix compliance). The rest of the parallel tests already use in the code the number of processes available in the communicator. (CMC - 2009/04/28) Tools ----- - h5diff new flag, -c, --compare, list objects that are not comparable. PVN - 2009/4/2 - 1368 - h5diff new flag, -N, --nan, avoids NaNs detection. PVN - 2009/4/2 - h5dump correctly specifies XML dtd / schema urls ADB - 2009/4/3 - 1519 - h5repack now handles group creation order. PVN - 2009/4/2 - 1402 - h5repack: When user doesn't specify a chunk size, h5repack now defines a default chunk size as the same size of the size of the hyperslab used to read the chunks. The size of the hyperslabs are defined as the size of each dimension or a predefined constant, whatever is smaller. This assures that the chunk read fits in the chunk cache. PVN - 2008/11/21 High-Level APIs --------------- - Table: In version 3.0 of Table, the writing of the "NROWS" attribute (used to store number of records) was deprecated. PVN - 2008/11/24 F90 API ------- - Added for the C APIs the Fortran wrappers: h5dget_access_plist_f h5iis_valid_f h5pset_chunk_cache_f h5pget_chunk_cache_f MSB - 2009/04/17 C++ API ------- - None Support for New Platforms, Languages, and Compilers =================================================== Bug Fixes since HDF5-1.8.2 ========================== Configuration ------------- - The --includedir=DIR configuration option now works as intended, and can be used to specify the location to install C header files. The default location remains unchanged, residing at ${prefix}/include. MAM - 2009/03/10 - BZ #1381 - Configure no longer removes the '-g' flag from CFLAGS when in production mode if it has been explicitly set in the CFLAGS environment variable prior to configuration. MAM - 2009/03/09 - BZ #1401 Library ------- - Added versioning to H5Z_class_t struct to allow compatibility with 1.6 API. NAF - 2009/04/20 - 1533 - Fixed a problem with using data transforms with non-native types in the file. NAF - 2009/04/20 - 1548 - Added direct.h include file to windows section of H5private.h to fix _getcwd() warning. ADB - 2009/04/14 - 1536 - Fixed a bug that prevented external links from working after calling H5close(). NAF - 2009/04/10 - 1539 - Modified library to write cached symbol table information to the superblock, to allow library versions 1.3.0 to 1.6.3 to read files created by this version. NAF - 2009/04/08 - 1423 - Changed skip lists to use a deterministic algorithm. The library should now never call rand() or srand(). NAF - 2009/04/08 - 503 - Fixed a bug where H5Lcopy and H5Lmove wouldn't create intermediate groups when that property was set. NAF - 2009/04/07 - 1526 - Fixed a bug that caused files with a user block to grow by the size of the user block every time they were opened. NAF - 2009/03/26 - 1499 - Fixed a rare problem that could occur with files using the old (pre 1.4) array datatype. NAF - 2009/03/23 - Modified library to be able to open files with corrupt root group symbol table messages, and correct these errors if they are found. Such files can only be successfully opened with write access. NAF - 2009/03/23 - 1189 - Removed the long_long #define and replaced all instances with "long long". This caused problems with third party products. All currently supported compliers support the type. ADB - 2009/03/05 - Fixed various bugs that could prevent the fill value from being written in certain rare cases. NAF - 2009/02/26 - 1469 - Fixed a bug that prevented more than one dataset chunk from being cached at a time. NAF - 2009/02/12 - 1015 - Fixed an assertion failure caused by opening an attribute multiple times through multiple file handles. NAF - 2009/02/12 - 1420 - Fixed a problem that could prevent the user from adding attributes (or any object header message) in some circumstances. NAF - 2009/02/12 - 1427 - Fixed a bug that could cause problems when an attribute was added to a committed datatype using the committed datatype's datatype. NAF - 2009/02/12 - Fixed a bug that could cause problems when copying an object with a shared message in its own object header. NAF - 2009/01/29 - Changed H5Tset_order to properly reject H5T_ORDER_NONE for most datatypes. NAF - 2009/01/27 - 1443 - Fixed a bug where H5Tpack wouldn't remove trailing space from an otherwise packed compound type. NAF - 2009/01/14 - Fixed up some old v2 btree assertions that get run in debug mode that were previously failing on compilation, and removed some of the more heavily outdated and non-rewritable ones. MAM - 2008/12/15 - Fixed a bug that could cause problems when "automatically" unmounting multiple files. NAF - 2008/11/17 - H5Dset_extent: when shrinking dimensions, some chunks were not deleted. PVN - 2009/01/8 Parallel Library ---------------- - None Tools ----- - Fixed many problems that could occur when using h5repack with named datatypes. NAF - 2009/4/20 - 1516/1466 - h5dump, h5diff, h5repack were not reading (by hyperslabs) datasets that have a datatype datum size greater than H5TOOLS_BUFSIZE, a constant defined as 1024Kb, such as array types with large dimensions. PVN - 2009/4/1 - 1501 - h5import: By selecting a compression type, a big endian byte order was being selected. PVN - 2009/3/11 - 1462 - zip_perf.c had missing argument on one of the open() calls. Fixed. AKC - 2008/12/9 F90 API ------ - None C++ API ------ - None High-Level APIs: ------ - Dimension scales: The scale index return value in H5DSiterate_scales was not always incremented. PVN - 2009/4/8 - 1538 Fortran High-Level APIs: ------ - Lite: The h5ltget_dataset_info_f function (gets information about a dataset) was not correctly returning the dimension array PVN - 2009/3/23 Platforms Tested ================ The following platforms and compilers have been tested for this release.

Known Problems ============== * 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 * There is a known issue in which HDF5 will change the timestamp on a file simply by opening it with read/write permissions, even if the file is not modified in any way. This is due to the way in which HDF5 manages the file superblock. A fix is currently underway and should be included in the 1.8.4 release of HDF5. MAM - 2009/04/28 * For gcc v4.3 and v4.4, with production mode, if -O3 is used, H5Tinit.c would fail to compile. Actually bad H5Tinit.c is produced. If -O (same as -O1) is used, H5Tinit.c compiled okay but test/dt_arith would fail. When -O0 (no optimizatio) is used, H5Tinit.c compilete okay and all tests passed. Therefore, -O0 is imposed for v4.3 and v4.4 of gcc. AKC - 2009/04/20 * 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. ======== Original tools/h5ls/testh5ls.sh ========= TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 ======== Change to =============================== echo SKIP TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 ================================================== ======== Original tools/h5copy/testh5copy.sh ========= TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested H5LSTEST $FILEOUT ======== Change to =============================== echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested echo SKIP H5LSTEST $FILEOUT ================================================== 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 * We have discovered two problems when running collective IO parallel HDF5 tests with chunking storage on the ChaMPIon MPI compiler on tungsten, a Linux cluster at NCSA. Under some complex selection cases: 1) MPI_Get_element returns the wrong value. 2) MPI_Type_struct also generates the wrong derived datatype and corrupt data may be generated. These issues arise only when turning on collective IO with chunking storage with some complex selections. We have not found these problems on other MPI-IO compilers. If you encounter these problems, you may use independent IO instead. To avoid this behavior, change the following line in your code H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE); to H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT); KY - 2007/08/24 * 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. * For LLNL, uP: both serial and parallel tests pass. Zeus: Serial tests pass but parallel tests fail with a known problem in MPI. ubgl: Serial tests pass but parallel tests fail. * 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. * On IRIX6.5, when the C compiler version is greater than 7.4, complicated MPI derived datatype code will work. However, the user should increase the value of the MPI_TYPE_MAX environment variable to some appropriate value to use collective irregular selection code. For example, the current parallel HDF5 test needs to raise MPI_TYPE_MAX to 200,000 to pass the test. * 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 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 platforms for serial mode. The parallel mode works fine with this option. It is suggested that you do not use this option on these platforms during configuration. * There is also a configure error on Altix machines that incorrectly reports when a version of Szip without an encoder is being used. * Information about building with PGI and Intel compilers is available in the INSTALL file sections 4.7 and 4.8. %%%%1.8.2%%%% HDF5 version 1.8.2 released on Mon Nov 10 15:43:09 CST 2008 ================================================================================ INTRODUCTION ============ This document describes the differences between HDF5-1.8.1 and HDF5 1.8.2, and contains information on the platforms tested and known problems in HDF5-1.8.2.

(MAM - 2008/10/15). Library ------- - Added two new public routines: H5Pget_elink_fapl() and H5Pset_elink_fapl(). (see bug #1247) (VC - 2008/10/13) - Improved free space tracking in file to be faster. (QAK - 2008/10/06) - Added 'mounted' field to H5G_info_t struct. (QAK - 2008/07/15) Parallel Library ---------------- - None Tools ----- - h5repack: added new options -u and -b to add a userblock to an HDF5 file during the repack. (PVN - 2008/08/26) - h5repack: added options -t and -a to call H5Pset_alignment while creating a repacked file. (PVN - 2008/08/29) - h5ls: added capability to traverse through external links when the -r (recursive) flag is given. (NAF - 2008/09/16) - h5ls: added -E option to enable traversal of external links. h5ls will not traverse external links without this flag being set. (NAF - 2008/10/06) - h5dump: when -b flag is used without a keyword after it, binary output defaults to NATIVE. MEMORY keyword was deprecated and replaced by NATIVE keyword. (PVN - 2008/10/30) - h5diff: returns 1 when file graphs differ by any object. Error return code was changed to 2 from -1. (PVN - 2008/10/30) - h5import: TEXTFPE (scientific format) was deprecated. Use TEXTFP instead (PVN - 2008/10/30) F90 API ------ - Added optional parameter 'mounted' to H5Gget_info_f, H5Gget_info_by_idx_f, H5Gget_info_by_name_f (MSB - 2008/09/24) - Added H5Tget_native_type_f (MSB - 2008/09/30) C++ API ------ - These member functions were added as wrapper for H5Rdereference to replace the incorrect IdComponent::dereference(). void H5Object::dereference(H5Object& obj, void* ref, H5R_type_t ref_type=H5R_OBJECT) void H5Object::dereference(H5File& h5file, void* ref, H5R_type_t ref_type=H5R_OBJECT) void H5Object::dereference(Attribute& obj, void* ref, H5R_type_t ref_type=H5R_OBJECT) In addition, these constructors were added to create the associated objects by way of dereference: DataSet(H5Object& obj, void* ref, H5R_type_t ref_type=H5R_OBJECT) DataSet(H5File& file, void* ref, H5R_type_t ref_type=H5R_OBJECT) DataSet(Attribute& attr, void* ref, H5R_type_t ref_type=H5R_OBJECT) Group(H5Object& obj, void* ref, H5R_type_t ref_type=H5R_OBJECT) Group(H5File& obj, void* ref, H5R_type_t ref_type=H5R_OBJECT) Group(Attribute& attr, void* ref, H5R_type_t ref_type=H5R_OBJECT) DataType(H5Object& obj, void* ref, H5R_type_t ref_type=H5R_OBJECT) DataType(H5File& file, void* ref, H5R_type_t ref_type=H5R_OBJECT) DataType(Attribute& attr, void* ref, H5R_type_t ref_type=H5R_OBJECT) (BMR - 2008/10/29) Support for New Platforms, Languages, and Compilers =================================================== - Intel 10.1 is supported on Mac OS X 10.5.4. Note: When Fortran is enabled, configure automatically disables the build of shared libraries (i.e., only static C and C++ HDF5 libraries will be built along with the static HDF5 Fortran library). Intel 10.1 C and C++ compilers require "-no-multibyte-chars" compilation flag due to the known bug in the compilers. (EIP - 2008/10/30) Bug Fixes since HDF5-1.8.1 ========================== Configuration ------------- - Fixed error with 'make check install' failing due to h5dump needing other tools built first. (MAM - 2008/10/15). - When using shared szip, it is no longer necessary to specify the path to the shared szip libraries in LD_LIBRARY_PATH. (MAM - 2008/10/15). - The file libhdf5_fortran.settings is not installed since its content is included in libhdf5.settings now. (AKC - 2008/10/21) - "make DESTDIR=xxx install" failed to install some tools and files (e.g., h5cc and fortran modules). Fixed. (AKC - 2008/10/8). Library ------- - H5Ovisit and H5Ovisit_by_name will now properly terminate when the callback function returns a positive value on the starting object. (NAF - 2008/11/03) - Fixed an error where a null message could be created that was larger than could be written to the file. (NAF - 2008/10/23) - Corrected error with family/split/multi VFD not updating driver info when "latest" version of the file format used. (QAK - 2008/10/14) - Corrected alignment+threshold errors to work correctly when metadata aggregation is enabled. (QAK - 2008/10/06) - Changed H5Fget_obj_count and H5Fget_obj_ids to ignore objects registered by the library for internal library use. (NAF - 2008/10/06) - Fixed potential memory leak during compound conversion. (NAF - 2008/10/06) - Changed the return value of H5Fget_obj_count from INT to SSIZE_T. Also changed the return value of H5Fget_obj_ids from HERR_T to SSIZE_T and the type of the parameter MAX_OBJS from INT to SIZE_T. (SLU - 2008/09/26) - Fixed an issue that could cause data to be improperly overwritten during compound type conversion. (NAF - 2008/09/19) - Fixed pointer alignment violations that could occur during vlen conversion. (NAF - 2008/09/16) - Fixed problem where library could cause a segmentation fault when an invalid location ID was given to H5Giterate(). (QAK - 2008/08/19) - Fixed improper shutdown when objects have reference count > 1. The library now tracks reference count due to the application separately from that due to internal library routines. (NAF - 2008/08/19) - Fixed assertion failure caused by incorrect array datatype version. (NAF - 2008/08/08) - Fixed an issue where mount point traversal would fail when using multiple handles for the child. (NAF - 2008/08/07) - Fixed an issue where mount points were inaccessible when using multiple file handles for the parent. The mount table is now in the shared file structure (the parent pointer is still in the top structure). (NAF - 2008/08/07) - Fixed assertion failure caused by incorrect array datatype version. (NAF - 2008/08/04) - Fixed issue where a group could have a file mounted on it twice. (QAK - 2008/07/15) - When an attribute was opened twice and data was written with one of the handles, the file didn't have the data. It happened because each handle had its own object structure, and the empty one overwrote the data with fill value. This is fixed by making some attribute information like the data be shared in the attribute structure. (SLU - 2008/07/07) - Fixed a Windows-specific issue in the ohdr test which was causing users in some timezones to get false errors. This a deficiency in the Windows mktime() function, and has been handled properly. (SJW - 2008/06/19) Parallel Library ---------------- - None Tools ----- - h5dump now checks for uniqueness of committed datatypes. (NAF - 2008/10/15) - Fixed unnecessary indentation of committed datatypes in h5dump. (NAF - 2008/10/15) - Fixed bugs in h5stat: segmemtation fault when printing groups and print warning message when traversal of objects is unsuccessful. (see bug #1253) (VC- 2008/10/13) - Fixed bug in h5ls that prevented relative group listings (like "h5ls foo.h5/bar") from working correctly (QAK - 2008/06/03) - h5dump: when doing binary output (-b), the stdout printing of attributes was done incorrectly. Removed printing of attributes when doing binary output. (PVN - 2008/06/05) F90 API ------ - h5sselect_elements_f: Added additional operators H5S_SELECT_APPEND and H5S_SELECT_PREPEND (MSB - 2008/09/30) - h5sget_select_elem_pointlist: Fixed list of returned points by rearranging the point list correctly by accounting for C conventions. (MSB - 2008/09/30) - h5sget_select_hyper_blocklist_f: Fixed error in transposed dimension of arrays.(MSB - 2008/9/30) - h5sget_select_bounds_f: Swapped array bounds to account for C and Fortran reversed array notation (MSB - 2008/9/30) - Changed to initializing string to a blank character instead of a null type in tH5P.f90 to fix compiling error using AIX 5.3.0 (MSB - 2008/7/29) - Fixed missing commas in H5test_kind.f90 detected by NAG compiler (MSB - 2008/7/29) - Fixed passing and array to a scalar in tH5A_1_8.f90 detected by NAG compiler (MSB - 2008/7/29) - Added the ability of the test programs to use the status of HDF5_NOCLEANUP to determine if the *.h5 files should be removed or not after the tests are completed (MSB - 2008/10/1) - In nh5tget_offset_c: (MSB 9/12/2008) If offset was equal to 0 it returned the error code of -1, this was changed to return an error code of -1 when the offset value is < 0. - Uses intrinsic Fortran function SIZEOF if available when detecting type of INTEGERs and REALs in H5test_kind.f90 (MSB - 2008/9/3) - Put the DOUBLE PRECISION interfaces in a separate module and added a USE statement for the module. The interfaces are included/excluded depending on the state of FORTRAN_DEFAULT_REAL is DBLE_F which detects if the default REAL is DOUBLE PRECISION. This allows the library to be compiled with -r8 Fortran flag without the user needing to edit the source code. (MSB - 200/8/27) - Enable building shared library for fortran by adding the flag -fPIC to the compile flags for versions of Intel Fortran compiler >=9 (MSB - 2008/8/26) C++ API ------ - Fixed a design bug which allowed an Attribute object to create/modify attributes (bugzilla #1068). The API class hierarchy was revised to address the problem. Classes AbstractDS and Attribute are moved out of H5Object. Class Attribute now multiply inherits from IdComponent and AbstractDs and class DataSet from H5Object and AbstractDs. In addition, the data member IdComponent::id was moved into subclasses: Attribute, DataSet, DataSpace, DataType, H5File, Group, and PropList. (BMR - 2008/05/20) - IdComponent::dereference was incorrect and replaced as described in "New Features" section.

Known Problems ============== * 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. ======== Original tools/h5ls/testh5ls.sh ========= TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 ======== Change to =============================== echo SKIP TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 ================================================== ======== Original tools/h5copy/testh5copy.sh ========= TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested H5LSTEST $FILEOUT ======== Change to =============================== echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested echo SKIP H5LSTEST $FILEOUT ================================================== 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 * We have discovered two problems when running collective IO parallel HDF5 tests with chunking storage on the ChaMPIon MPI compiler on tungsten, a Linux cluster at NCSA. Under some complex selection cases: 1) MPI_Get_element returns the wrong value. 2) MPI_Type_struct also generates the wrong derived datatype and corrupt data may be generated. These issues arise only when turning on collective IO with chunking storage with some complex selections. We have not found these problems on other MPI-IO compilers. If you encounter these problems, you may use independent IO instead. To avoid this behavior, change the following line in your code H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE); to H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT); KY - 2007/08/24 * 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. * For LLNL, uP: both serial and parallel tests pass. Zeus: Serial tests pass but parallel tests fail with a known problem in MPI. ubgl: Serial tests pass but parallel tests fail. * 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. * On IRIX6.5, when the C compiler version is greater than 7.4, complicated MPI derived datatype code will work. However, the user should increase the value of the MPI_TYPE_MAX environment variable to some appropriate value to use collective irregular selection code. For example, the current parallel HDF5 test needs to raise MPI_TYPE_MAX to 200,000 to pass the test. * 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 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 platforms for serial mode. The parallel mode works fine with this option. It is suggested that you do not use this option on these platforms during configuration. * There is also a configure error on Altix machines that incorrectly reports when a version of Szip without an encoder is being used. * Information about building with PGI and Intel compilers is available in the INSTALL file sections 4.7 and 4.8. %%%%1.8.1%%%% HDF5 version 1.8.1 released on Thu May 29 15:28:55 CDT 2008 ================================================================================ INTRODUCTION ============ This document describes the differences between the HDF5-1.8.1 release and HDF5 1.8.0, and contains information on the platforms tested and known problems in HDF5-1.8.1. For more details, see the files HISTORY-1_0-1_8_0_rc3.txt and HISTORY-1_8.txt in the release_docs/ directory of the HDF5 source.

(AKC - 2008/05/18) - The new configure option "--disable-sharedlib-rpath" disables embedding the '-Wl,-rpath' information into executables when shared libraries are produced, and instead solely relies on the information in LD_LIBRARY_PATH. (MAM - 2008/05/15) - Configuration suite now uses Autoconf 2.61, Automake 1.10.1, and Libtool 2.2.2 (MAM - 2008/05/01) Source code distribution ======================== Library ------- - None Parallel Library ---------------- - None Tools ----- - h5repack: Reinstated the -i and -o command line flags to specify input and output files. h5repack now understands both the old syntax (with -i and -o) and the new syntax introduced in Release 1.8.0. (PVN - 2008/05/23) - h5dump: Added support for external links, displaying the object that an external link points to. (PVN - 2008/05/12) - h5dump: Added an option, -m, to allow user-defined formatting in the output of floating point numbers. (PVN - 2008/05/06) - h5dump, in output of the -p option: Added effective data compression ratio to the dataset storage layout output when a compression filter has been applied to a dataset. (PVN - 2008/05/01) F90 API ------ New H5A, H5G, H5L, H5O, and H5P APIs to enable 1.8 features were added. See "Release 1.8.1 (current release) versus Release 1.8.0" in the document "HDF5 Software Changes from Release to Release" (http://hdfgroup.org/HDF5/doc/ADGuide/Changes.html) for the complete list of the new APIs. C++ API ------ - None Support for New Platforms, Languages, and Compilers =================================================== - Both serial and parallel HDF5 are supported for the Red Storm machine which is a Cray XT3 system. - The Fortran library will work correctly if compiled with the -i8 flag. This has been tested with the g95, PGI and Intel Fortran compilers. Bug Fixes since HDF5-1.8.0 ========================== Configuration ------------- - None Source code distribution ======================== Library ------- - Chunking: Chunks greater than 4GB are disallowed. (QAK - 2008/05/16) - Fixed the problem with searching for a target file when following an external link. The search pattern will depend on whether the target file's pathname is an absolute or a relative path. Please see the H5Lcreate_external description in the "HDF5 Reference Manual" (http://hdfgroup.org/HDF5/doc/RM/RM_H5L.html). (VC - 2008/04/08) - Fixed possible file corruption bug when encoding datatype descriptions for compound datatypes whose size was between 256 and 511 bytes and the file was opened with the "use the latest format" property enabled (with H5Pset_libver_bounds). (QAK - 2008/03/13) - Fixed bug in H5Aget_num_attrs() routine to correctly handle an invalid location identifier. (QAK - 2008/03/11) Parallel Library ---------------- - None Tools ----- - Fixed bug in h5diff that prevented datasets and attributes with variable-length string elements from comparing correctly. (QAK - 2008/02/28) - Fixed bug in h5dump that caused binary output to be made only for the first dataset, when several datasets were requested. (PVN - 2008/04/07) F90 API ------ - The h5tset(get)_fields subroutines were missing the parameter to specify a sign position; fixed. (EIP - 2008/05/23) - Many APIs were fixed to work with the 8-byte integers in Fortran vs. 4-byte integers in C. This change is trasparent to user applications. C++ API ------ - The class hierarchy was revised to address the problem reported in bugzilla #1068, Attribute should not be derived from base class H5Object. Classes AbstractDS was moved out of H5Object. Class Attribute now multiply inherits from IdComponent and AbstractDs and class DataSet from H5Object and AbstractDs. In addition, data member IdComponent::id was moved into subclasses: Attribute, DataSet, DataSpace, DataType, H5File, Group, and PropList. (BMR - 2008/05/20) - IdComponent::dereference was incorrect; it was changed from: void IdComponent::dereference(IdComponent& obj, void* ref) to: void H5Object::dereference(H5File& h5file, void* ref) void H5Object::dereference(H5Object& obj, void* ref) (BMR - 2008/05/20) - Revised Attribute::write and Attribute::read wrappers to handle memory allocation/deallocation properly. (bugzilla 1045) (BMR - 2008/05/20) Platforms Tested ================ The following platforms and compilers have been tested for this release.

Compiler versions for each platform are listed in the preceding "Platforms Tested" table. Known Problems ============== * 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 * For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh will fail on the test "Testing h5ls -w80 -r -g tgroup.h5" fails. This test is expected to fail and 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. To bypass this problem for now, change the following lines in the tools/h5ls/testh5ls.sh. ======== Original ========= # The following combination of arguments is expected to return an error message # and return value 1 TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 ======== Skip the test ========= echo SKIP TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5 ======== end of bypass ======== AKC - 2008/05/28 * We have discovered two problems when running collective IO parallel HDF5 tests with chunking storage on the ChaMPIon MPI compiler on tungsten, a Linux cluster at NCSA. Under some complex selection cases: 1) MPI_Get_element returns the wrong value. 2) MPI_Type_struct also generates the wrong derived datatype and corrupt data may be generated. These issues arise only when turning on collective IO with chunking storage with some complex selections. We have not found these problems on other MPI-IO compilers. If you encounter these problems, you may use independent IO instead. To avoid this behavior, change the following line in your code H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE); to H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT); KY - 2007/08/24 * For SNL, spirit/liberty/thunderbird: The serial tests pass but parallel tests failed with MPI-IO file locking message. AKC - 2007/6/25 * 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. * For LLNL, uP: both serial and parallel tests pass. Zeus: Serial tests pass but parallel tests fail with a known problem in MPI. ubgl: Serial tests pass but parallel tests fail. * Configuring with --enable-debug=all produces compiler errors on most platforms: Users who want to run HDF5 in debug mode should use --enable-debug rather than --enable-debug=all to enable debugging information on most modules. * On Mac OS 10.4, test/dt_arith.c has some errors in conversion from long double to (unsigned) long long and from (unsigned) long long to long double. * On Altix SGI with Intel 9.0, testmeta.c would not compile with -O3 optimization flag. * On VAX, the Scaleoffset filter is not supported. The Scaleoffset filter supports only the IEEE standard for floating-point data; it cannot be applied to HDF5 data generated on VAX. * On Cray X1, a lone colon on the command line of h5dump --xml (as in the testh5dumpxml.sh script) is misinterpereted by the operating system and causes an error. * 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. * On IRIX6.5, when the C compiler version is greater than 7.4, complicated MPI derived datatype code will work. However, the user should increase the value of the MPI_TYPE_MAX environment variable to some appropriate value to use collective irregular selection code. For example, the current parallel HDF5 test needs to raise MPI_TYPE_MAX to 200,000 to pass the test. * 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 * For version 6 (6.02 and 6.04) of the Portland Group compiler on the AMD Opteron processor, there is a bug in the compiler for optimization(-O2). The library failed in several tests, all related to the MULTI driver. The problem has been reported to the vendor. * 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 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 platforms for serial mode. The parallel mode works fine with this option. It is suggested that you do not use this option on these platforms during configuration. * With the gcc 2.95.2 compiler, HDF5 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 ./dsets tests fail on 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. * Not all platforms behave correctly with Szip's shared libraries. Szip is disabled in these cases, and a message is relayed at configure time. Static libraries should be working on all systems that support Szip and should be used when shared libraries are unavailable. There is also a configure error on Altix machines that incorrectly reports when a version of Szip without an encoder is being used. * On some platforms that use Intel and Absoft compilers to build the HDF5 Fortran library, compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90 complaining about the exit subroutine. Comment out the line IF (total_error .ne. 0) CALL exit (total_error). * Information about building with PGI and Intel compilers is available in the INSTALL file sections 4.7 and 4.8. * 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 HDF5 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 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. * H5Ocopy() does not copy reg_ref attributes correctly when shared-message is turn on. The value of the reference in the destination attriubte is wrong. This H5Ocopy problem will affect the h5copy tool. * In the C++ API, it appears that there are bugs in Attribute::write/read and DataSet::write/read for fixed- and variable-len strings. The problems are being worked on and a patch will be provided when the fixes are available. %%%%1.8.0%%%% HDF5 version 1.8.0 released on Tue Feb 12 20:41:19 CST 2008 ================================================================================ INTRODUCTION ============ This document describes the differences between the HDF5-1.6.x release series and HDF5 1.8.0, and contains information on the platforms tested and known problems in HDF5-1.8.0. For more details, see the HISTORY-1_0-1_8_0_rc3.txt file in the release_docs/ directory of the HDF5 source.

Compiler versions for each platform are listed in the preceding "Platforms Tested" table. Known Problems ============== * We have discovered two problems when running collective IO parallel HDF5 tests with chunking storage on the ChaMPIon MPI compiler on tungsten, a Linux cluster at NCSA. Under some complex selection cases: 1) MPI_Get_element returns the wrong value. 2) MPI_Type_struct also generates the wrong derived datatype and corrupt data may be generated. These issues arise only when turning on collective IO with chunking storage with some complex selections. We have not found these problems on other MPI-IO compilers. If you encounter these problems, you may use independent IO instead. To avoid this behavior, change the following line in your code H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE); to H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT); KY - 2007/08/24 * For SNL, spirit/liberty/thunderbird: The serial tests pass but parallel tests failed with MPI-IO file locking message. AKC - 2007/6/25 * 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. * For SNL, Red Storm: Only parallel HDF5 is supported. The serial tests pass when run against the parallel library; the parallel tests also pass, but with lots of non-fatal error messages. * For LLNL, uP: both serial and parallel tests pass. Zeus: Serial tests pass but parallel tests fail with a known problem in MPI. ubgl: Serial tests pass but parallel tests fail. * On SUN 5.10 C++, testing fails in the "Testing Shared Datatypes with Attributes" test. * Configuring with --enable-debug=all produces compiler errors on most platforms: Users who want to run HDF5 in debug mode should use --enable-debug rather than --enable-debug=all to enable debugging information on most modules. * On Mac OS 10.4, test/dt_arith.c has some errors in conversion from long double to (unsigned) long long and from (unsigned) long long to long double. * On Altix SGI with Intel 9.0, testmeta.c would not compile with -O3 optimization flag. * On VAX, the Scaleoffset filter is not supported. The filter cannot be applied to HDF5 data generated on VAX. The Scaleoffset filter only supports the IEEE standard for floating-point data. * On Cray X1, a lone colon on the command line of h5dump --xml (as in the testh5dumpxml.sh script) is misinterpereted by the operating system and causes an error. * 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. * On IRIX6.5, when the C compiler version is greater than 7.4, complicated MPI derived datatype code will work. However, the user should increase the value of the MPI_TYPE_MAX environment variable to some appropriate value to use collective irregular selection code. For example, the current parallel HDF5 test needs to raise MPI_TYPE_MAX to 200,000 to pass the test. * 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 calculating code 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 * For version 6 (6.02 and 6.04) of the Portland Group compiler on the AMD Opteron processor, there is a bug in the compiler for optimization(-O2). The library failed in several tests, all related to the MULTI driver. The problem has been reported to the vendor. * 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 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 do not use this option on these platforms during configuration. * With the gcc 2.95.2 compiler, HDF5 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 ./dsets tests fail on 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. * Not all platforms behave correctly with Szip's shared libraries. Szip is disabled in these cases, and a message is relayed at configure time. Static libraries should be working on all systems that support Szip and should be used when shared libraries are unavailable. There is also a configure error on Altix machines that incorrectly reports when a version of Szip without an encoder is being used. * On some platforms that use Intel and Absoft compilers to build the HDF5 Fortran library, compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90 complaining about the exit subroutine. Comment out the line IF (total_error .ne. 0) CALL exit (total_error). * Information about building with PGI and Intel compilers is available in the INSTALL file sections 4.7 and 4.8. * 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 HDF5 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. * H5Ocopy() does not copy reg_ref attributes correctly when shared-message is turn on. The value of the reference in the destination attriubte is wrong. This H5Ocopy problem will affect the h5copy tool.
