- New Features
- Support for New Platforms, Languages, and Compilers
- Bug Fixes since HDF5-1.8.20
- Supported Platforms
- Supported Configuration Features Summary
- More Tested Platforms
- Known Problems
New Features
============
Tools
-----
- h5diff
h5diff has new option enable-error-stack.
Updated h5diff with the --enable-error-stack argument, which
enables the display of the hdf5 error stack. This completes the
improvement to the main tools; h5copy, h5diff, h5dump, h5ls and
h5repack.
(ADB - 2017/08/30, HDFFV-9774)
C++ API
-------
- The following C++ API wrappers have been added to the C++ Library:
// Creates a binary object description of this datatype.
void DataType::encode() - C API H5Tencode()
// Returns the decoded type from the binary object description.
DataType::decode() - C API H5Tdecode()
ArrayType::decode() - C API H5Tdecode()
CompType::decode() - C API H5Tdecode()
DataType::decode() - C API H5Tdecode()
EnumType::decode() - C API H5Tdecode()
FloatType::decode() - C API H5Tdecode()
IntType::decode() - C API H5Tdecode()
StrType::decode() - C API H5Tdecode()
VarLenType::decode() - C API H5Tdecode()
// Three overloaded functions to retrieve information about an object
H5Location::getObjectInfo() - H5Oget_info()/H5Oget_info_by_name()
(BMR - 2017/10/17, HDFFV-10175)
- New constructors to open existing datatypes added in ArrayType,
CompType, DataType, EnumType, FloatType, IntType, StrType, and
VarLenType.
(BMR - 2017/10/17, HDFFV-10175)
- A document is added to the HDF5 C++ API Reference Manual to show the
mapping from a C API to C++ wrappers. It can be found from the main
page of the C++ API Reference Manual.
(BMR - 2017/10/17, HDFFV-10151)
High-Level APIs
---------------
- H5DOread_chunk
Users wanted to read compressed data directly from a file without any
processing by the HDF5 data transfer pipeline, just as they were able
to write it directly to a file with H5DOwrite_chunk.
New API function, corresponding to existing function H5DOwrite_chunk.
H5DOread_chunk reads a raw data chunk directly from a chunked dataset
in the file into the application buffer, bypassing the library’s internal
data transfer pipeline, including filters.
(VC - 2017/05/02, HDFFV-9934)
Support for New Platforms, Languages, and Compilers
===================================================
- Added NAG compiler
Bug Fixes since HDF5-1.8.19
===========================
Configuration
-------------
- cmake
The hdf5 library used shared szip and zlib, which needlessly required
applications to link with the same szip and zlib libraries.
Changed the target_link_libraries commands to use the static libs.
Removed improper link duplication of szip and zlib.
Adjusted the link dependencies and the link interface values of
the target_link_libraries commands.
(ADB - 2017/11/14, HDFFV-10329)
- cmake MPI
CMake implementation for MPI was problematic and would create incorrect
MPI library references in the hdf5 libraries.
Reworked the CMake MPI code to properly create CMake targets.Also merged
the latest CMake FindMPI.cmake changes to the local copy. This is necessary
until HDF changes the CMake minimum to 3.9 or greater.
(ADB - 2017/11/02, HDFFV-10321)
- Fixed Fortran linker flags when using the NAG Fortran compiler (autotools).
(HDFFV-10037, MSB, 2017/10/21)
- cmake
Too many commands for POST_BUILD step caused command line to be
too big on windows.
Changed foreach of copy command to use a custom command with the
use of the HDFTEST_COPY_FILE macro.
(ADB - 2017/07/12, HDFFV-10254)
Library
-------
- filter plugin handling in H5PL.c and H5Z.c
It was discovered that the dynamic loading process used by
filter plugins had issues with library dependencies.
CMake build process changed to use LINK INTERFACE keywords, which
allowed HDF5 C library to make dependent libraries private. The
filter plugin libraries no longer require dependent libraries
(such as szip or zlib) to be available.
(ADB - 2017/11/16, HDFFV-10328)
- Fix rare object header corruption bug
In certain cases, such as when converting large attributes to dense
storage, an error could occur which would either fail an assertion or
cause file corruption. Fixed and added test.
(NAF - 2017/11/14, HDFFV-10274)
- H5Zfilter_avail in H5Z.c
The public function checked for plugins, while the private
function did not.
Modified H5Zfilter_avail and private function, H5Z_filter_avail.
Moved check for plugin from public to private function. Updated
H5P__set_filter due to change in H5Z_filter_avail. Updated tests.
(ADB - 2017/10/10, HDFFV-10297, HDFFV-10319)
- Fix H5Sencode bug when num points selected is >2^32
Modified to fail if the 32 bit limit is exceeded when encoding either
offsets or counts in the selection.
(HDFFV-10323, VC, 2017/09/07)
- Fix H5HL_offset_into()
(1) Fix H5HL_offset_into() to return error when offset exceeds heap data
block size.
(2) Fix other places in the library that call this routine to detect
error routine.
(HDFFV-10216, VC, 2017/09/05)
Tools
-----
- h5repack
h5repack failed to copy a dataset with existing filter.
Reworked code for h5repack and h5diff code in tools library. Added
improved error handling, cleanup of resources and checks of calls.
Modified H5Zfilter_avail and private function, H5Z_filter_avail.
Moved check for plugin from public to private function. Updated
H5P__set_filter due to change in H5Z_filter_avail. Updated tests.
Note, h5repack output display has changed to clarify the individual
steps of the repack process. The output indicates if an operation
applies to all objects. Lines with notation and no information
have been removed.
(ADB - 2017/10/10, HDFFV-10297, HDFFV-10319)
- h5repack
h5repack always set the User Defined filter flag to H5Z_FLAG_MANDATORY.
Added another parameter to the 'UD=' option to set the flag by default
to '0' or H5Z_FLAG_MANDATORY, the other choice is '1' or H5Z_FLAG_OPTIONAL.
(ADB - 2017/08/31, HDFFV-10269)
- h5ls
h5ls generated error on stack when it encountered a H5S_NULL
dataspace.
Adding checks for H5S_NULL before calling H5Sis_simple (located
in the h5tools_dump_mem function) fixed the issue.
(ADB - 2017/08/17, HDFFV-10188)
- h5dump
h5dump segfaulted on output of XML file.
Function that escape'd strings used the full buffer length
instead of just the length of the replacement string in a
strncpy call. Using the correct length fixed the issue.
(ADB - 2017/08/01, HDFFV-10256)
- h5diff
h5diff segfaulted on compare of a NULL variable length string.
Improved h5diff compare of strings by adding a check for
NULL strings and setting the lengths to zero.
(ADB - 2017/07/25, HDFFV-10246)
- h5import
h5import crashed trying to import data from a subset of a dataset.
Improved h5import by adding the SUBSET keyword. h5import understands
to use the Count times the Block as the size of the dimensions.
Added INPUT_B_ORDER keyword to old-style configuration files.
The import from h5dump function expects the binary files to use native
types (FILE '-b' option) in the binary file.
(ADB - 2017/06/15, HDFFV-10219)
C++ API
-------
- Marked the following functions deprecated because they were moved to
class H5Object:
H5Location::createAttribute()
H5Location::openAttribute()
H5Location::attrExists()
H5Location::removeAttr()
H5Location::renameAttr()
H5Location::getNumAttrs()
(BMR - 2017/10/17)

Known Problems
==============
The dynamically loaded plugin test libraries require undefined references
to HDF5 functions to be resolved at runtime in order to function properly.
With autotools on CYGWIN this results in build errors, and we have not
found a solution that satisfies both. Therefore the dynamically loaded
plugin tests have been disabled on CYGWIN.
Mac OS X 10.13 added additional subdirectory structure in .libs for shared
libraries. Consequently "make check" will fail testing java and dynamically
loaded plugin test libraries attempting to copy files from the previous
locations in .libs directories. This will be addressed in the next release
when support for the Mac OS X 10.13 platform is added.
Known problems in previous releases can be found in the HISTORY*.txt files
in the HDF5 source. Please report any new problems found to
help@hdfgroup.org.
