HDF5 version 1.8.21-snap11 currently under development
================================================================================
INTRODUCTION
============
This document describes the differences between HDF5-1.8.20 and
HDF5-1.8.21, and contains information on the platforms tested and
known problems in HDF5-1.8.21.
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 1.8.21 source code, documentation, and additional materials
can be found on the HDF5 web page at:
https://support.hdfgroup.org/HDF5/
The HDF5 1.8.21 release can be obtained from:
https://support.hdfgroup.org/HDF5/release/obtain518.html
User documentation for 1.8.21 can be accessed directly at this location:
https://support.hdfgroup.org/HDF5/doc1.8/
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:
https://support.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 1.8.21 (current
release) versus Release 1.8.20

New Features
============
Configuration
-------------
- CMake
Change minimum version to 3.10.
This change removes the need to support a copy of the FindMPI.cmake module,
which has been removed, along with its subfolder in the config/cmake_ext_mod
location.
(ADB - 2018/03/09)
- CMake
Add pkg-config file generation
Added pkg-config file generation for the C, C++, HL, and HL C++ libraries.
In addition, builds on linux will create h5cXXX scripts that use the pkg-config
files. This is a limited implementation of a script like autotools h5cc.
(ADB - 2018/03/08, HDFFV-4359)
- CMake
Refactor use of CMAKE_BUILD_TYPE for new variable, which understands
the type of generator in use.
Added new configuration macros to use new HDF_BUILD_TYPE variable. This
variable is set correctly for the type of generator being used for the build.

Support for New Platforms, Languages, and Compilers
===================================================
Bug Fixes since HDF5-1.8.20
===========================
Configuration
-------------
- CMake
Update CMake commands configuration.
A number of improvements were made to the CMake commands. Most
changes simplify usage or eliminate unused constructs. Also,
some changes support better cross-platform support.
(ADB - 2018/02/01, HDFFV-10398)
- CMake
Correct usage of CMAKE_BUILD_TYPE variable.
The use of the CMAKE_BUILD_TYPE is incorrect for multi-config
generators (Visual Studio and XCode) and is optional for single
config generators. Created a new macro to check
GLOBAL PROPERTY -> GENERATOR_IS_MULTI_CONFIG
Created two new HDF variable, HDF_BUILD_TYPE and HDF_CFG_BUILD_TYPE.
Defaults for these variables is "Release".
(ADB - 2018/01/10, HDFFV-10385)
- CMake
Add replacement of fortran flags if using static CRT.
Added TARGET_STATIC_CRT_FLAGS call to HDFUseFortran.cmake file in
config/cmake_ext_mod folder.
(ADB - 2018/01/08, HDFFV-10334)
Library
-------
- Utility function can not handle lowercase Windows drive letters
Added call to toupper function for drive letter.
(ADB - 2017/12/18, HDFFV-10307)
Parallel Library
----------------
- None
Performance
-------------
- None
Tools
-----
- h5repack
h5repack changes the chunk parameters when a change of layout is not
specified and a filter is applied.
HDFFV-10297, HDFFV-10319 reworked code for h5repack and h5diff code
in the tools library. The check for an existing layout was incorrectly
placed into an if block and not executed. The check was moved into
the normal path of the function.
(ADB - 2018/02/21, HDFFV-10412)
- h5dump
the tools library will hide the error stack during file open.
While this is preferable almost always, there are reasons to enable
display of the error stack when a tool will not open a file. Adding an
optional argument to the --enable-error-stack will provide this use case.
As an optional argument it will not affect the operation of the
--enable-error-stack. h5dump is the only tool to implement this change.
(ADB - 2018/02/15, HDFFV-10384)
- h5dump
h5dump would output an indented blank line in the filters section.
h5dump overused the h5tools_simple_prefix function, which is a
function intended to account for the data index (x,y,z) option.
Removed the function call for header information.
(ADB - 2018/01/25, HDFFV-10396)
- h5repack
h5repack incorrectly searched internal object table for name.
h5repack would search the table of objects for a name, if the
name did not match it tried to determine if the name without a
leading slash would match. The logic was flawed! The table
stored names(paths) without a leading slash and did a strstr
of the table path to the name.
The assumption was that if there was a difference of one then
it was a match, however "pressure" would match "/pressure" as
well as "/pressure1", "/pressure2", etc. Changed logic to remove
any leading slash and then do a full compare of the name.
(ADB - 2018/01/18, HDFFV-10393)
- h5repack
h5repack failed to handle more then 9 chars for int conversion.
User defined filter parameter conversions would fail for integers
larger then 9 characters. Increased local variable array for storing
the current command line parameter to prevent buffer overflows.
(ADB - 2018/01/17, HDFFV-10392)
- h5diff
h5diff seg-faulted if comparing VL strings against fixed strings.
Reworked solution for HDFFV-8625 and HDFFV-8639. Implemented the check
for string objects of same type in the diff_can_type function by
adding an if(tclass1 == H5T_STRING) block. This if block moves the
same check that was added for attributes to this function, which is
used by all object types. This function also handles complex type
structures.
Also added a new test file in h5diffgenttest for testing this issue
and removed the temporary files used in the test scripts.

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.
