+- Bug Fixes since HDF5-1.8.0
+- Platforms Tested
+- Known Problems
+
+
+New Features
+============
+
+ Configuration:
+ -------------
+ - Configuration suite now uses Libtool 2.2.6a. MAM 2008/10/24
+
+ - Configuration suite now uses Autoconf 2.61, Automake 1.10.1.
+ MAM 2008/05/05.
+
+ - 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)
+
+ Library:
+ --------
+ - 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 form 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 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:
+ -----------------
+
+ Fortran Library:
+ ----------------
+
+ C++ Library:
+ ------------
+ - These member functions were added as wrapper for H5Rdereference to
+ replace the incorrect IdComponent::dereference().
+ void H5Object::dereference(H5File& h5file, void* ref)
+ void H5Object::dereference(H5Object& obj, void* ref)
+ In addition, these constructors were added to create the associated
+ objects by way of dereference:
+ Attribute(H5Object& obj, void* ref);
+ Attribute(H5File& file, void* ref);
+ DataSet(H5Object& obj, void* ref);
+ DataSet(H5File& file, void* ref);
+ DataType(H5Object& obj, void* ref);
+ DataType(H5File& file, void* ref);
+ Group(H5Object& obj, void* ref);
+ Group(H5File& obj, void* ref);
+ (BMR - 2008/08/10)
+
+
+
+ Tools:
+ ------
+
+ - h5dump: added a printing of the compression ratio of uncompressed and compressed
+ sizes for cases where compression filters are present. (PVN - 2008/05/01)
+ - h5dump: added an option to allow a user defined formatting string for printf
+ regarding floating point numbers. (PVN - 2008/05/06)
+ - h5dump: support for external links, display the object that the external link
+ points to. (PVN - 2008/05/12)
+ - h5repack: add a userblock to an HDF5 file during the repack. (PVN - 2008/08/26)
+ - h5repack: add 2 options that call H5Pset_alignment in the 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)
+ - h5diff: added support for long double (PVN - 2008/10/28)
+ - h5dump: binary output defaults to NATIVE with -b optionally accepting
+ the form of binary output (NATIVE, FILE, BE, LE). (PVN - 2008/10/30)
+ - h5diff: return 1 for file differences when both 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)
+ - h5repack: Define a default chunk whose size is manageable. (PVN - 2008/11/21)
+
+
+

+
+Bug Fixes since HDF5-1.8.0 release
+==================================
+
+ Library
+ -------
+ - 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)
+ - 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)
+ - 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 - 2008/07/22
+ - Fixed issue where a group could have a file mounted on it twice.
+ (QAK - 2008/07/15)
+ - 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
+ - Fixed the problem with the searching of target file for H5Lcreate_external().
+ The searching pattern will depend on whether the target file's
+ pathname is an absolute or a relative path. Please see the description
+ in the RM for H5Lcreate_external(). (VC - 2008/04/08)
+ - Fixed possible file corruption bug when encoding datatype
+ descriptions for compound datatypes whose size was between
+ 256 & 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 handle invalid location
+ ID correctly. (QAK - 2008/03/11)
+
+
+ Configuration
+ -------------
+ - Fixed error with 'make check install' failing due to h5dump
+ needing other tools built first. MAM - 2008/10/24.
+ - When using shared szip, it is no longer necessary to specify
+ the path to the shared szip libraries in LD_LIBRARY_PATH. MAM -
+ 2008/10/24.
+ - 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.
+
+ Performance
+ -------------
+
+ Tools
+ -----
+ - zip_perf.c had missing argument on one of the open() calls. Fixed.
+ (AKC - 2008/12/9)
+ - 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)
+ - Fixed bug in h5diff that prevented datasets & attributes with
+ variable-length string elements from comparing correctly.
+ (QAK - 2008/02/28)
+ - h5import bug on Windows w/binary datasets. fread in windows needs a
+ binary file to be open with 'rb' instead of 'r' otherwise it
+ terminates execution if an end of file character is found on the
+ input file. Besides that the binary file generated needs to be open
+ with 'wb' , otherwise an end of line character is read twice.
+ (PVN - 2008/02/19)
+ - 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)
+ - 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
+
+
+
+
+ Documentation
+ -------------
+
+
+ F90 APIs
+ --------
+
+
+ C++ APIs
+ --------
+ - Fixed bug that caused segfaults in Attribute::read. (BMR - 2008/04/20)
+ - Fixed bug in PropList::getClassName to use portable HDfree instead
+ of free. (BMR - 2008/04/20)
+ - 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 - 2008/08/10)
+ - IdComponent::dereference was incorrect and replaced as described
+ in "New Features" section.

+
+Known Problems
+==============
+* We discovered two problems when running collective IO parallel HDF5 tests
+ with chunking storage on 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 wrong derived data type and corrupt data
+ may be generated.
+ This only happens when turning on collective IO with chunking storage
+ with some complex selections. We haven't found these problems on other
+ MPI-IO compilers. If you encounter these problems, you may use Independent IO
+ instead.
+
+ 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. Higher level of optimization
+ causes failures in several HDF5 library tests.
+* For HPUX 11.23 many tools tests failed for 64-bit version when linked to the
+ shared libraries (tested for 1.8.0-beta2)
+* For SNL, Red Storm: only paralle HDF5 is supported. The serial tests pass
+ and the parallel tests also pass with lots of non-fatal error messages.
+* For LLNL, uP: both serial and parallel pass. Zeus: serial passes but
+ parallel fails with a known proglem in MPI. ubgl: serial passes but
+ parallel fails.
+* on SUN 5.10 C++ test 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, Scaleoffset filter isn't supported. The filter cannot be applied to
+ HDF5 data generated on VAX. Scaleoffset filter only supports 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, we found that if more than two processes
+ contribute no IO and the application asks to do IO with collective, we found
+ that when using 4 processors, a simple collective write will be hung
+ sometimes. This can be verified with t_mpi test under testpar.
+* On IRIX6.5, when C compiler version >7.4, the complicate MPI derived data type
+ code will work. However, the user should be aware to enlarge MPI_TYPE_MAX environment
+ variable to some certian value in order to use collective irregular selection code.
+ For example, the current parallel HDF5 test needs to enlarge MPI_TYPE_MAX to
+ 200,000 to make the test pass.
+* The dataset created or rewritten with the v1.6.3 library or after can't
+ be read with the v1.6.2 library or before when 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 wasn't 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 is no
+ longer the same as before on little-endian system. The library release
+ after 1.6.4 can still read the dataset created or rewritten with the library
+ of v1.6.2 or before. SLU - 2005/6/30
+* For the version 6(6.02 and 6.04) of Portland Group compiler on AMD Opteron
+ processor, there's a bug in the compiler for optimization(-O2). The library
+ failed in several tests but all related to 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". HDF5 does not use sockets (except for stream-VFD). This is
+ due to problems of the poe command trying to set up the debug socket.
+ Check if there are many old /tmp/s.pedb.* staying around. These are
+ sockets used by the poe command and left behind due to failed commands.
+ Ask your system administrator to clean them out. Lastly, request IBM
+ to provide a mean to run poe without the debug socket.
+
+* The C++ library's tests fails when compiling with PGI C++ compiler. The
+ workaround until the problem is correctly handled is to use the
+ flag "--instantiate=local" prior to the configure and build steps, as:
+ setenv CXX "pgCC --instantiate=local" for pgCC 5.02 and higher
+
+
+* The stream-vfd test uses ip port 10007 for testing. If another
+ application is already using that port address, the test will hang
+ indefinitely and has to be terminated by the kill command. To try the
+ test again, change the port address in test/stream_test.c to one not
+ being used in the host.
+
+* The --enable-static-exec configure flag fails to compile for Solaris
+ platforms. This is due to the fact that not all of the system
+ libraries on Solaris are available in a static format.
+
+ The --enable-static-exec configure flag also fails to correctly compile
+ on IBM SP2 platform for the serial mode. The parallel mode works fine
+ with this option.
+
+ It is suggested that you don't use this option on these platforms
+ during configuration.
+
+* With the gcc 2.95.2 compiler, HDF 5 uses the `-ansi' flag during
+ compilation. The ANSI version of the compiler complains about not being
+ able to handle the `long long' datatype with the warning:
+
+ warning: ANSI C does not support `long long'
+
+ This warning is innocuous and can be safely ignored.
+
+
+* The Stream VFD was not tested yet under Windows. It is not supported
+ in the TFLOPS machine.
+
+
+* The ./dsets tests failed in the TFLOPS machine if the test program,
+ dsets.c, is compiled with the -O option. The hdf5 library still works
+ correctly with the -O option. The test program works fine if it is
+ compiled with -O1 or -O0. Only -O (same as -O2) causes the test
+ program to fail.
+
+* Certain platforms give false negatives when testing h5ls:
+ - Cray J90 and Cray T90IEEE give errors during testing when displaying
+ some floating-point values. These are benign differences due to
+ the different precision in the values displayed and h5ls appears to
+ be dumping floating-point numbers correctly.
+
+* 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 HDF5 fortran library,
+ compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90
+ complaining about exit subroutine. Comment out the line
+ IF (total_error .ne. 0) CALL exit (total_error)
+
+* Information about building with PGI and Intel compilers is available in
+ INSTALL file sections 5.7 and 5.8
+
+* On at least one system, (SDSC DataStar), the scheduler (in this case
+ LoadLeveler) sends job status updates to standard error when you run
+ any executable that was compiled with the parallel compilers.
+
+ This causes problems when running "make check" on parallel builds, as
+ many of the tool tests function by saving the output from test runs,
+ and comparing it to an exemplar.
+
+ The best solution is to reconfigure the target system so it no longer
+ inserts the extra text. However, this may not be practical.
+
+ In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to
+ the configure and build. This will cause "make check" to continue after
+ detecting errors in the tool tests. However, in the case of SDSC DataStar,
+ it also leaves you with some 150 "failed" tests to examine by hand.
+
+ A second solution is to write a script to run serial tests and filter
+ out the text added by the scheduler. A sample script used on SDSC
+ DataStar is given below, but you will probably have to customize it
+ for your installation.
+
+ Observe that the basic idea is to insert the script as the first item
+ on the command line which executes the the test. The script then
+ executes the test and filters out the offending text before passing
+ it on.
+
+ #!/bin/csh
+
+ set STDOUT_FILE=~/bin/serial_filter.stdout
+ set STDERR_FILE=~/bin/serial_filter.stderr
+
+ rm -f $STDOUT_FILE $STDERR_FILE
+
+ ($* > $STDOUT_FILE) >& $STDERR_FILE
+
+ set RETURN_VALUE=$status
+
+ cat $STDOUT_FILE
+
+ tail +3 $STDERR_FILE
+
+ exit $RETURN_VALUE
+
+ You get the HDF make files and test scipts to execute your filter script
+ by setting the environment variable "RUNSERIAL" to the full path of the
+ script prior to running configure for parallel builds. Remember to
+ "unsetenv RUNSERIAL" before running configure for a serial build.
+
+ Note that the RUNSERIAL environment variable exists so that we can
+ can prefix serial runs as necessary on the target system. On DataStar,
+ no prefix is necessary. However on an MPICH system, the prefix might
have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to
get the serial tests to run at all.
