[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 1.10.1nb1, Package name: hdf5-1.10.1nb1, Maintainer: pkgsrc-users

HDF5 is a data model, library, and file format for storing and
managing data. It supports an unlimited variety of datatypes, and
is designed for flexible and efficient I/O and for high volume and
complex data. HDF5 is portable and is extensible, allowing applications
to evolve in their use of HDF5. The HDF5 Technology suite includes
tools and applications for managing, manipulating, viewing, and
analyzing data in the HDF5 format.

Update devel/hdf5 and devel/hdf5-c++ to version 1.8.18.

New Features
============

    Configuration
    -------------

    - CMake: Added NAMESPACE hdf5:: to package configuration files to allow
      projects using installed HDF5 binaries built with CMake to link with
      them without specifying the HDF5 library location via IMPORTED_LOCATION.

      (ADB, 2016/10/17, HDFFV-10003)

    - CMake: Changed the CTEST_BUILD_CONFIGURATION option to
      CTEST_CONFIGURATION_TYPE as recommended by the CMake documentation.

      (ADB, 2016/10/17, HDFFV-9971)

    - CMake: Added support for GIT

      (ADB, 2016/07/12)

Bug Fixes since HDF5-1.8.17
===========================

    Configuration
    -------------

    - Fixed a problem preventing HDF5 to be built on 32-bit CYGWIN by
      condensing cygwin configuration files into a single file and
      removing outdated compiler settings.

      (ABD, 2016/07/12, HDFFV-9946)

    - CMake: Fixed a command length overflow error by converting custom
      commands inside CMakeTest.cmake files into regular dependencies and
      targets.

      (ABD, 2016/07/12, HDFFV-9939)

    - CMake: Fixed a timeout error that would occasionally occur when running
      the virtual file driver tests simultaneously due to test directory and file
      name collisions.

      (ABD, 2016/09/19, HDFFV-9431)

    Library
    -------

    - Fixed a memory leak that would occur when the library allocated memory
      for an external file prefix (H5Pset_efile_prefix) and failed to free it.

      (DER, 2016/04/29)

    - Fixed an error that would occur when calling H5Adelete on an attribute
      which is attached to an externally linked object in the target file and
      whose datatype is a committed datatype in the main file.

      (VC, 2016-07-04, HDFFV-9940)

    - Fixed a problem where a plugin compiled into a DLL in the default plugin
      directory could not be found by the HDF5 library at runtime on Windows
      when the HDF5_PLUGIN_PATH environment variable was not set.

      (ABD, 2016/08/01, HDFFV-9706)

    - Fixed an issue where H5Pset_alignment could result in misaligned blocks
      with some input combinations, causing an assertion failure in debug mode.

      (NAF, 2016/08/11, HDFFV-9948)

    - A number of issues were fixed when reading/writing from/to corrupted
      files to ensure that the library fails gracefully in these cases:

      * Writing to a corrupted file that has an object message which is
        incorrectly marked as sharable on disk results in a buffer overflow /
        invalid write instead of a clean error message.

      * Decoding data from a corrupted file with a dataset encoded with the
        H5Z_NBIT decoding can result in a code execution vulnerability under
        the context of the application using the HDF5 library.

      * When decoding an array datatype from a corrupted file, the HDF5 library
        fails to return an error in production if the number of dimensions
        decoded is greater than the maximum rank.

      * When decoding an "old style" array datatype from a corrupted \ 
file, the
        HDF5 library fails to return an error in production if the number of
        dimensions decoded is greater than the maximum rank.

      (NAF, 2016/10/06, HDFFV-9950, HDFFV-9951, HDFFV-9992, HDFFV-9993)

    - Fixed an error that would occur when copying an object with an attribute
      which is a compound datatype consisting of a variable length string.

      (VC, 2016-10-17, HDFFV-7991)

    Parallel Library
    ----------------

    - Fixed a bug that could occur when allocating a chunked dataset in parallel
      with an alignment set and an alignment threshold greater than the chunk
      size but less than or equal to the raw data aggregator size.

      (NAF, 2016/08/11, HDFFV-9969)

    Performance
    -------------
    - None

    Tools
    -----

    - Fixed an error in the compiler wrapper scripts (h5cc, h5fc, et al.)
      in which they would erroneously drop the file argument specified via
      the -o flag when the -o flag was specified before the -c flag on the
      command line, resulting in a failure to compile.

      (LRK, 2016/06/08, HDFFV-9938, HDFFV-9530)

    - h5repack User Defined (UD) filter parameters were not parsed correctly.

      The UD filter parameters were not being parsed correctly. Reworked coding
      section to parse the correct values and verify number of parameters.

      (ADB, 2016/10/19, HDFFV-9996, HDFFV-9974, HDFFV-9515, HDFFV-9039)

    Fortran API
    -----------

    - Fortran library fails to compile and fails tests with NAG compiler.

      * Removed the non-standard assumption that KIND=SIZEOF, in the HDF5
        configure programs.
      * Removed Fortran 66 character/integer conversions from tests.
      * Removed the use of C_SIZEOF in the test programs
      * Changed to using STORAGE_SIZE in the test programs if available. Otherwise,
        uses C_SIZEOF or SIZEOF.

      (MSB, 2016/9/22, HDFFV-9973)

    - Fortran segfaults for F03 tests with NAG compiler

      * Removed INTENT(OUT) from 'fillvalue' in F2003 interface
        for H5Pget_fill_value_f.

      (MSB, 2016/9/22, HDFFV-9980)

    C++ API
    -------

    - The macro H5_NO_NAMESPACE is deprecated from the HDF5 C++ API library.
      In future releases, the macros H5_NO_STD and OLD_HEADER_FILENAME may
      also be removed.

      (BMR, 2016/10/27, HDFFV-9532)

    High-Level APIs:
    ---------------

    - The high-level API Packet Table (PT) did not write data correctly when
      the datatype is a compound type that has string type as one of the
      members.  This problem started in 1.8.15, after the fix of HDFFV-9042
      was applied, which caused the Packet Table to use native type to access
      the data.  It should be up to the application to specify whether the
      buffer to be read into memory in the machine’s native architecture.
      Thus, the PT is fixed to not use native type but to make a copy of the
      user's provided datatype during creation or the packet table's datatype
      during opening.  If an application wishes to use native type to read the
      data, then the application will request that.  However, the Packet Table
      doesn't provide a way to specify memory datatype in this release.  This
      feature will be available in future releases, HDFFV-10023.

      (BMR, 2016/10/27, HDFFV-9758)

Known Problems
==============
* On windows platforms in debug configurations, the VFD flush1 tests will fail
  with the split and multi VFD drivers. These tests will display a modal debug
  dialog which must be answered or wait for the test timeout to expire.
  (ADB - 2014/06/23 - HDFFV-8851)

* CLANG compiler with the options -fcatch-undefined-behavior and -ftrapv
  catches some undefined behavior in the alignment algorithm of the macro DETECT_I
  in H5detect.c (Issue 8147).  Since the algorithm is trying to detect the alignment
  of integers, ideally the flag -fcatch-undefined-behavior shouldn't to be used for
  H5detect.c. In the future, we can separate flags for H5detect.c from the rest of
  the library. (SLU - 2013/10/16)

* Make provided by Solaris fails in "make check". Solaris users should use
  gmake to build and install the HDF5 software. (AKC - 2013/10/08 - HDFFV-8534)

* The C++ and FORTRAN bindings are not currently working on FreeBSD with the
  native release 8.2 compilers (4.2.1), but are working with gcc 4.6 from the
  ports (and probably gcc releases after that).
  (QAK - 2012/10/19)

* The following h5dump test case fails in BG/P machines (and potentially other
  machines that use a command script to launch executables):

   h5dump --no-compact-subset -d "AHFINDERDIRECT::ah_centroid_t[0] it=0 \ 
tl=0"
     tno-subset.h5

  This is due to the embedded spaces in the dataset name being interpreted
  by the command script launcher as meta-characters, thus passing three
  arguments to h5dump's -d flag. The command passes if run by hand, just
  not via the test script.
  (AKC - 2012/05/03)

* The STDIO VFD does not work on some architectures, possibly due to 32/64
  bit or large file issues.  The basic STDIO VFD test is known to fail on
  64-bit SunOS 5.10 on SPARC when built with -m64 and 32-bit OS X/Darwin
  10.7.0.  The STDIO VFD test has been disabled while we investigate and
  a fix should appear in a future release.
  (DER - 2011/10/14 - HDFFV-8235)

* h5diff can report inconsistent results when comparing datasets of enum type
  that contain invalid values.  This is due to how enum types are handled in
  the library and will be addressed in a future release.
  (DER - 2011/10/14 - HDFFV-7527)

* The links test can fail under the stdio VFD due to some issues with external
  links.  This will be investigated and fixed in a future release.
  (DER - 2011/10/14 - HDFFV-7768)

* 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)

* 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. the issue. HL and C++ shared libraries should now be
  working as intended, however.
  (MAM - 2011/04/20)

* 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/exampl … _problems/
  (NAF - 2011/01/19)

* 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 - 2010/02/02)

* 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.
  (MAM - 2009/11/04)

* 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.

   2016-10-09 20:44:35 by Alexander Nasonov | Files touched by this commit (10) | Package updated
Log message:
Update hdf5 to 1.8.17.

New Features
============

    Configuration
    -------------
    - Cmakehdf5: Added Ability to Run Multiple Make Commands

      Added option --njobs to specify up to how many jobs to launch during
      build (cmake) and testing (ctest).

      (AKC - 2015/12/13, HDFFV-9612)

    - Cmakehdf5: Added Szip Support and Verbose Option

      Added --with-szlib to support the Szip library; and
      --enable/disable-verbose to display all CMake process output.

      (AKC - 2015/11/16, HDFFV-8932 and DAILYTEST-195)

    - CMake minimum is now 3.1.0. (ADB - 2015/11/14)

    - Large File System (LFS) Support has Changed in the Autotools

      We assume that fseeko and ftello exist.

      The *64 I/O functions and types are no longer explicitly used.
      We now rely on a mapping provided by _FILE_OFFSET_BITS (or its
      equivalent).

      _LARGEFILE(64)_SOURCE is no longer exposed via AM_CPPFLAGS.

      (DER - 2016/03/29, HDFFV-9626 and HDFFV-9541)

    Library
    -------
    - New API Calls for Searching for External Dataset Storage

      API calls that determine the search path for dataset external
      storage were added. H5Pset/get_efile_prefix() API calls were added
      to the library. These functions give control over the search path
      for dataset external storage that has been configured with
      H5Pset_external().

      Additionally, the HDF5_EXTFILE_PREFIX environment variable can be
      used to control the search path.

      (DER - 2016/04/20, HDFFV-8740)

    High-Level APIs
    ---------------

    C Packet Table API
    ------------------
    - Replacement of a Public Function with H5PTcreate

      The existing function H5PTcreate_fl limits applications so they
      can use the deflate compression only. The public function
      H5PTcreate has been added to replace H5PTcreate_fl. H5PTcreate
      takes a property list identifier to provide flexibility on
      creation properties.  This also removes the following warning:
      "deprecated conversion from string constant to "char*"
      [-Wwrite-strings]".

      (BMR - 2016/04/25, HDFFV-9708, HDFFV-8615)

    - New Public Functions: H5PTget_dataset and H5PTget_type

      Two accessor functions have been added. H5PTget_dataset returns
      the identifier of the dataset associated with the packet table,
      and H5PTget_type returns the identifier of the datatype used by
      the packet table.

      (BMR - 2016/04/25, HDFFV-8623 patch 3)

    - Regarding #ifdef VLPT_REMOVED

      The #ifdef VLPT_REMOVED blocks have been removed from the packet
      table (PT) library source except for the following functions:
        + H5PTis_varlen() has been made available again
        + H5PTfree_vlen_readbuff() is now H5PTfree_vlen_buff()

      (BMR - 2016/04/25, HDFFV-442)

    C++ Packet Table API
    --------------------
    - New Constructor in FL_PacketTable

      An overloaded constructor has been added to FL_PacketTable and
      takes a property list identifier to provide flexibility on
      creation properties such as compression.

      FL_PacketTable(hid_t fileID, const char* name, hid_t dtypeID,
                       hsize_t chunkSize = 0, hid_t plistID = H5P_DEFAULT)

      (BMR - 2016/04/25, HDFFV-8623 patch 5)

    - New Member Functions in PacketTable

      Two accessor wrappers were added to class PacketTable.

      PacketTable::GetDataset() returns the identifier of the dataset
      associated with the packet table, and PacketTable::GetDatatype()
      returns the identifier of the datatype that the packet table uses.

      (BMR - 2016/04/25, HDFFV-8623 patch 4)

    - New Member Functions with "char*" as an Argument

      Overloaded functions were added to provide the "const char*"
      argument; the existing version will be deprecated in future
      releases. This also removes the following warning:
      "deprecated conversion from string constant to "char*"
      [-Wwrite-strings]".

      (BMR - 2016/04/25, HDFFV-8623 patch 1, HDFFV-8615)

    - Regarding #ifdef VLPT_REMOVED

      The #ifdef VLPT_REMOVED blocks have been removed from the packet
      table library source code except for the following functions:
        + VL_PacketTable::IsVariableLength() was moved to PacketTable
        + VL_PacketTable::FreeReadBuff() is now PacketTable::FreeBuff()

      (BMR - 2016/04/25, HDFFV-442)

    C++ API
    -------
    - New Member Function in DSetCreatPropList

      DSetCreatPropList::setNbit() was added to setup N-bit compression for
      a dataset.

      (BMR - 2016/04/25, HDFFV-8623 patch 7)

    - New Overloaded "const" Member Functions in ArrayType

      The two following functions were added:
        ArrayType::getArrayNDims() const
        ArrayType::getArrayDims() const
      to provide const version, and the non-const version was marked
      deprecated. In-memory array information, ArrayType::rank and
      ArrayType::dimensions, were removed. This is an implementation
      detail and should not affect applications.

      (BMR, 2016/04/25, HDFFV-9725)

     - New member function added

       The assignment operator ArrayType::operator= is added because ArrayType
       has pointer data members.

       (BMR, 2016/03/07, HDFFV-9562)

Support for New Platforms, Languages, and Compilers
===================================================
    - Mac OS X El Capitan 10.11.4 with compilers Apple clang/clang++
      version 7.3.0 from Xcode 7.3, gfortran GNU Fortran (GCC) 5.2.0
      and Intel icc/icpc/ifort version 16.0.2

Bug Fixes since HDF5-1.8.16
===========================

    Configuration
    -------------
    - Updated Linux Language Level Flags to Match the Autotools. Removed
      Linux-specific Flags from OS X.

      An addition to the flags simply being out of sync with the Autotools,
      the Linux flags were used on OS X builds which led to symbols not being
      found. Although this was non-fatal and compilation continued (implicit
      definitions were used by the compiler and the symbols resolved at link
      time), a large number of warnings were raised.

      Linux changes:

      * CHANGED:    _POSIX_C_SOURCE (from 199605 to 200112L)
      * ADDED:      _GNU_SOURCE
      * REMOVED:    _BSD_SOURCE
      * REMOVED:    _DEFAULT_SOURCE

      (DER - 2015/12/08, HDFFV-9627)

    - The --enable-clear-file-buffers configure Option was Non-functional
      so the Feature was Always Enabled (its default value).

      Regardless of the configure flag, the setting was always enabled when
      the Autotools were used to configure HDF5. This was due to the "no"
      option being processed after the "*" option in configure.ac so \ 
"*"
      matched first. CMake was unaffected.

      The option now works correctly.

      NOTE that builders are always advised to leave this option enabled.
      When disabled, buffers that are written to disk may contain the
      memory's previous contents, which may include secure information.
      The performance overhead of the feature (a single memset call per
      allocation) is minimal.

      (DER - 2016/02/03, HDFFV-9676)

    - Added a patch to remove '"'s from arguments for MPI compilers that
      were causing errors compiling H5lib_settings.c with SGI MPT.

      (LRK - 2016/04/20, HDFFV-9439)

    Library
    -------
    - Fixed shared file pointer problem which caused a crash when running a
      program provided by a user.

      (VC - 2016/04/01, HDFFV-9469)

    - Fixed some format string warnings that prevent compiling with
      -Werror=format-security on gcc.

      These only appeared in error messages and would not cause problems
      under normal operation.

      (DER - 2016/01/13, HDFFV-9640)

    - Fixed a library segmentation fault when accessing a corrupted
      file provided by a user.

      (MSC - 2016/02/19, HDFFV-9670)

    Tools
    -----
    - h5dump: Sub-setting Fixed for Dimensions Greater than Two

      When a dataset has more than two dimensions, sub-setting would
      incorrectly calculate the data that needed to be displayed.
      Added in block and stride calculations that account for dimensions
      greater than two. NOTE: lines that have line breaks inserted
      because of display length calculations may have index info that
      is incorrect until the next dimension break.

      (ADB - 2016/03/07, HDFFV-9698)

    - h5dump: Issue with Argument Segmentation Fault

      When an argument with an optional value was at the end of the command
      line with a value, h5dump would crash. Reworked check for remaining
      arguments.

      (ADB - 2016/03/07, HDFFV-9570, HDFFV-9684)

    - h5dump: Issue with Default Fill Value

      Added all default cases of fill value to the display of fill value.

      (ADB -, 2016/03/07, HDFFV-9241)

    - h5dump: Clarified Help

      Clarified usage of -O F option in h5dump utility help.

      (ADB - 2016/03/07, HDFFV-9066)

    - h5dump: Issue with Double Free Fault

      Added a check for filename not null before calling free().

      (ADB - 2016/01/27, HDFFV-9639)

    - VS2015 Release Changed how Timezone was Handled

      Created a function, HDget_timezone, in H5system.c. Replaced
      timezone variable usage with function call.

      (ADB - 2015/11/02, HDFFV-9550)

    C++ API
    -------
    - Removal of Obsolete Methods

      The overloaded methods which had parameters that should be const
      but were not have been removed.

      (BMR - 2016/01/13, HDFFV-9789)

    High-Level APIs:
    ---------------
    - Fixed Memory Leak in Packet Table API

      Applied user's patch to fix memory leak in the creation of a
      packet table.

      (BMR - 2016/04/25, HDFFV-9700)

* 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.

* 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.
