New Features
============
Configuration:
-------------
- Added new CMake options for building and running HDF5 API tests
(Experimental)
HDF5 API tests are an experimental feature, primarily targeted
toward HDF5 VOL connector authors, that is currently being developed.
These tests exercise the HDF5 API and are being integrated back
into the HDF5 library from the HDF5 VOL tests repository
(https://github.com/HDFGroup/vol-tests). To support this feature,
the following new options have been added to CMake:
* HDF5_TEST_API: ON/OFF (Default: OFF)
Controls whether the HDF5 API tests will be built. These tests
will only be run during testing of HDF5 if the HDF5_TEST_SERIAL
(for serial tests) and HDF5_TEST_PARALLEL (for parallel tests)
options are enabled.
* HDF5_TEST_API_INSTALL: ON/OFF (Default: OFF)
Controls whether the HDF5 API test executables will be installed
on the system alongside the HDF5 library. This option is currently
not functional.
* HDF5_TEST_API_ENABLE_ASYNC: ON/OFF (Default: OFF)
Controls whether the HDF5 Async API tests will be built. These
tests will only be run if the VOL connector used supports Async
operations.
* HDF5_TEST_API_ENABLE_DRIVER: ON/OFF (Default: OFF)
Controls whether to build the HDF5 API test driver program. This
test driver program is useful for VOL connectors that use a
client/server model where the server needs to be up and running
before the VOL connector can function. This option is currently
not functional.
* HDF5_TEST_API_SERVER: String (Default: "")
Used to specify a path to the server executable that the test
driver program should execute.
- Added support for CMake presets file.
CMake supports two main files, CMakePresets.json and CMakeUserPresets.json,
that allow users to specify common configure options and share them with others.
HDF added a CMakePresets.json file of a typical configuration and support
file, config/cmake-presets/hidden-presets.json.
Also added a section to INSTALL_CMake.txt with very basic explanation of the
process to use CMakePresets.
- Deprecated and removed old SZIP library in favor of LIBAEC library
LIBAEC library has been used in HDF5 binaries as the szip library of choice
for a few years. We are removing the options for using the old SZIP library.
- Enabled instrumentation of the library by default in CMake for parallel
debug builds
HDF5 can be configured to instrument portions of the parallel library to
aid in debugging. Autotools builds of HDF5 turn this capability on by
default for parallel debug builds and off by default for other build types.
CMake has been updated to match this behavior.
- Added new option to build libaec and zlib inline with CMake.
Using the CMake FetchContent module, the external filters can populate
content at configure time via any method supported by the ExternalProject
module. Whereas ExternalProject_Add() downloads at build time, the
FetchContent module makes content available immediately, allowing the
configure step to use the content in commands like add_subdirectory(),
include() or file() operations.
The HDF options (and defaults) for using this are:
BUILD_SZIP_WITH_FETCHCONTENT:BOOL=OFF
LIBAEC_USE_LOCALCONTENT:BOOL=OFF
BUILD_ZLIB_WITH_FETCHCONTENT:BOOL=OFF
ZLIB_USE_LOCALCONTENT:BOOL=OFF
The CMake variables to control the path and file names:
LIBAEC_TGZ_ORIGPATH:STRING
LIBAEC_TGZ_ORIGNAME:STRING
ZLIB_TGZ_ORIGPATH:STRING
ZLIB_TGZ_ORIGNAME:STRING
See the CMakeFilters.cmake and config/cmake/cacheinit.cmake files for usage.
Library:
--------
- Added a Subfiling VFD configuration file prefix environment variable
The Subfiling VFD now checks for values set in a new environment
variable "H5FD_SUBFILING_CONFIG_FILE_PREFIX" to determine if the
application has specified a pathname prefix to apply to the file
path for its configuration file. For example, this can be useful
for cases where the application wishes to write subfiles to a
machine's node-local storage while placing the subfiling configuration
file on a file system readable by all machine nodes.
- Added H5Pset_selection_io(), H5Pget_selection_io(), and
H5Pget_no_selection_io_cause() API functions to manage the selection I/O
feature. This can be used to enable collective I/O with type conversion,
or it can be used with custom VFDs that support vector or selection I/O.
- Added H5Pset_modify_write_buf() and H5Pget_modify_write_buf() API
functions to allow the library to modify the contents of write buffers, in
order to avoid malloc/memcpy. Currently only used for type conversion
with selection I/O.
Parallel Library:
-----------------

Fortran Library:
----------------
- Fortran async APIs H5A, H5D, H5ES, H5G, H5F, H5L and H5O were added.
- Added Fortran APIs:
h5pset_selection_io_f, h5pget_selection_io_f
h5pset_modify_write_buf_f, h5pget_modify_write_buf_f

Bug Fixes since HDF5-1.14.0 release
===================================
Library
-------
- Fixed a bug in H5Ocopy that could generate invalid HDF5 files
H5Ocopy was missing a check to determine whether the new object's
object header version is greater than version 1. Without this check,
copying of objects with object headers that are smaller than a
certain size would cause H5Ocopy to create an object header for the
new object that has a gap in the header data. According to the
HDF5 File Format Specification, this is not allowed for version
1 of the object header format.
Fixes GitHub issue #2653
- Fixed H5Pget_vol_cap_flags and H5Pget_vol_id to accept H5P_DEFAULT
H5Pget_vol_cap_flags and H5Pget_vol_id were updated to correctly
accept H5P_DEFAULT for the 'plist_id' FAPL parameter. Previously,
they would fail if provided with H5P_DEFAULT as the FAPL.
- Fixed ROS3 VFD anonymous credential usage with h5dump and h5ls
ROS3 VFD anonymous credential functionality became broken in h5dump
and h5ls in the HDF5 1.14.0 release with the added support for VFD
plugins, which changed the way that the tools handled setting of
credential information that the VFD uses. The tools could be
provided the command-line option of "--s3-cred=(,,)" as a workaround
for anonymous credential usage, but the documentation for this
option stated that anonymous credentials could be used by simply
omitting the option. The latter functionality has been restored.
Fixes GitHub issue #2406
- Fixed memory leaks when processing malformed object header continuation messages
Malformed object header continuation messages can result in a too-small
buffer being passed to the decode function, which could lead to reading
past the end of the buffer. Additionally, errors in processing these
malformed messages can lead to allocated memory not being cleaned up.
This fix adds bounds checking and cleanup code to the object header
continuation message processing.
Fixes GitHub issue #2604
- Fixed memory leaks, aborts, and overflows in H5O EFL decode
The external file list code could call assert(), read past buffer
boundaries, and not properly clean up resources when parsing malformed
external data files messages.
This fix cleans up allocated memory, adds buffer bounds checks, and
converts asserts to HDF5 error checking.
Fixes GitHub issue #2605
- Fixed potential heap buffer overflow in decoding of link info message
Detections of buffer overflow were added for decoding version, index
flags, link creation order value, and the next three addresses. The
checkings will remove the potential invalid read of any of these
values that could be triggered by a malformed file.
Fixes GitHub issue #2603
- Memory leak
Memory leak was detected when running h5dump with "pov". The memory was allocated
via H5FL__malloc() in hdf5/src/H5FL.c
The fuzzed file "pov" was an HDF5 file containing an illegal continuation message.
When deserializing the object header chunks for the file, memory is allocated for the
array of continuation messages (cont_msg_info->msgs) in continuation message info struct.
As error is encountered in loading the illegal message, the memory allocated for
cont_msg_info->msgs needs to be freed.
Fixes GitHub issue #2599
- Fixed memory leaks that could occur when reading a dataset from a
malformed file
When attempting to read layout, pline, and efl information for a
dataset, memory leaks could occur if attempting to read pline/efl
information threw an error, which is due to the memory that was
allocated for pline and efl not being properly cleaned up on error.
Fixes GitHub issue #2602
- Fixed potential heap buffer overrun in group info header decoding from malformed file
H5O__ginfo_decode could sometimes read past allocated memory when parsing a
group info message from the header of a malformed file.
It now checks buffer size before each read to properly throw an error in these cases.
Fixes GitHub issue #2601
- Fixed potential buffer overrun issues in some object header decode routines
Several checks were added to H5O__layout_decode and H5O__sdspace_decode to
ensure that memory buffers don't get overrun when decoding buffers read from
a (possibly corrupted) HDF5 file.
- Fixed a heap buffer overflow that occurs when reading from
a dataset with a compact layout within a malformed HDF5 file
During opening of a dataset that has a compact layout, the
library allocates a buffer that stores the dataset's raw data.
The dataset's object header that gets written to the file
contains information about how large of a buffer the library
should allocate. If this object header is malformed such that
it causes the library to allocate a buffer that is too small
to hold the dataset's raw data, future I/O to the dataset can
result in heap buffer overflows. To fix this issue, an extra
check is now performed for compact datasets to ensure that
the size of the allocated buffer matches the expected size
of the dataset's raw data (as calculated from the dataset's
dataspace and datatype information). If the two sizes do not
match, opening of the dataset will fail.
Fixes GitHub issue #2606
- Fixed a memory corruption issue that can occur when reading
from a dataset using a hyperslab selection in the file
dataspace and a point selection in the memory dataspace
When reading from a dataset using a hyperslab selection in
the dataset's file dataspace and a point selection in the
dataset's memory dataspace where the file dataspace's "rank"
is greater than the memory dataspace's "rank", memory corruption
could occur due to an incorrect number of selection points
being copied when projecting the point selection onto the
hyperslab selection's dataspace.
- Fixed issues in the Subfiling VFD when using the SELECT_IOC_EVERY_NTH_RANK
or SELECT_IOC_TOTAL I/O concentrator selection strategies
Multiple bugs involving these I/O concentrator selection strategies
were fixed, including:
* A bug that caused the selection strategy to be altered when
criteria for the strategy was specified in the
H5FD_SUBFILING_IOC_SELECTION_CRITERIA environment variable as
a single value, rather than in the old and undocumented
'integer:integer' format
* Two bugs which caused a request for 'N' I/O concentrators to
result in 'N - 1' I/O concentrators being assigned, which also
lead to issues if only 1 I/O concentrator was requested
Also added a regression test for these two I/O concentrator selection
strategies to prevent future issues.
- Fix CVE-2021-37501 / GHSA-rfgw-5vq3-wrjf
Check for overflow when calculating on-disk attribute data size.
A bogus hdf5 file may contain dataspace messages with sizes
which lead to the on-disk data sizes to exceed what is addressable.
When calculating the size, make sure, the multiplication does not
overflow.
The test case was crafted in a way that the overflow caused the
size to be 0.
Fixes GitHub #2458
- Fixed an issue with collective metadata writes of global heap data
New test failures in parallel netCDF started occurring with debug
builds of HDF5 due to an assertion failure and this was reported in
GitHub issue #2433. The assertion failure began happening after the
collective metadata write pathway in the library was updated to use
vector I/O so that parallel-enabled HDF5 Virtual File Drivers (other
than the existing MPI I/O VFD) can support collective metadata writes.
The assertion failure was fixed by updating collective metadata writes
to treat global heap metadata as raw data, as done elsewhere in the
library.
Fixes GitHub issue #2433
- Fixed buffer overflow error in image decoding function.
The error occurred in the function for decoding address from the specified
buffer, which is called many times from the function responsible for image
decoding. The length of the buffer is known in the image decoding function,
but no checks are produced, so the buffer overflow can occur in many places,
including callee functions for address decoding.
The error was fixed by inserting corresponding checks for buffer overflow.
Fixes GitHub issue #2432
Java Library
------------
-
Configuration
-------------
- Fixed improper include of Subfiling VFD build directory
With the release of the Subfiling Virtual File Driver feature, compiler
flags were added to the Autotools build's CPPFLAGS and AM_CPPFLAGS
variables to always include the Subfiling VFD source code directory,
regardless of whether the VFD is enabled and built or not. These flags
are needed because the header files for the VFD contain macros that are
assumed to always be available, such as H5FD_SUBFILING_NAME, so the
header files are unconditionally included in the HDF5 library. However,
these flags are only needed when building HDF5, so they belong in the
H5_CPPFLAGS variable instead. Inclusion in the CPPFLAGS and AM_CPPFLAGS
variables would export these flags to the h5cc and h5c++ wrapper scripts,
as well as the libhdf5.settings file, which would break builds of software
that use HDF5 and try to use or parse information out of these files after
deleting temporary HDF5 build directories.
Fixes GitHub issue #2621
- Correct the CMake generated pkg-config file
The pkg-config file generated by CMake had the order and placement of the
libraries wrong. Also added support for debug library names.
Changed the order of Libs.private libraries so that dependencies come after
dependents. Did not move the compression libraries into Requires.private
because there was not a way to determine if the compression libraries had
supported pkconfig files. Still recommend that the CMake config file method
be used for building projects with CMake.
Fixes GitHub issues #1546 and #2259
- Force lowercase Fortran module file names
The Cray Fortran compiler uses uppercase Fortran module file names, which
caused CMake installs to fail. A compiler option was added to use lowercase
instead.
Tools
-----
- Names of objects with square brackets will have trouble without the
special argument, --no-compact-subset, on the h5dump command line.
h5diff did not have this option and now it has been added.
Fixes GitHub issue #2682
- In the tools traverse function - an error in either visit call
will bypass the cleanup of the local data variables.
Replaced the H5TOOLS_GOTO_ERROR with just H5TOOLS_ERROR.
Fixes GitHub issue #2598

Known Problems
==============
CMake files do not behave correctly with paths containing spaces.
Do not use spaces in paths because the required escaping for handling spaces
results in very complex and fragile build files.
ADB - 2019/05/07
At present, metadata cache images may not be generated by parallel
applications. Parallel applications can read files with metadata cache
images, but since this is a collective operation, a deadlock is possible
if one or more processes do not participate.
CPP ptable test fails on both VS2017 and VS2019 with Intel compiler, JIRA
issue: HDFFV-10628. This test will pass with VS2015 with Intel compiler.
The subsetting option in ph5diff currently will fail and should be avoided.
The subsetting option works correctly in serial h5diff.
Several tests currently fail on certain platforms:
MPI_TEST-t_bigio fails with spectrum-mpi on ppc64le platforms.
MPI_TEST-t_subfiling_vfd and MPI_TEST_EXAMPLES-ph5_subfiling fail with
cray-mpich on theta and with XL compilers on ppc64le platforms.
MPI_TEST_testphdf5_tldsc fails with cray-mpich 7.7 on cori and theta.
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.
CMake vs. Autotools installations
=================================
While both build systems produce similar results, there are differences.
Each system produces the same set of folders on linux (only CMake works
on standard Windows); bin, include, lib and share. Autotools places the
COPYING and RELEASE.txt file in the root folder, CMake places them in
the share folder.
The bin folder contains the tools and the build scripts. Additionally, CMake
creates dynamic versions of the tools with the suffix "-shared". Autotools
installs one set of tools depending on the "--enable-shared" configuration
option.
build scripts
-------------
Autotools: h5c++, h5cc, h5fc
CMake: h5c++, h5cc, h5hlc++, h5hlcc
The include folder holds the header files and the fortran mod files. CMake
places the fortran mod files into separate shared and static subfolders,
while Autotools places one set of mod files into the include folder. Because
CMake produces a tools library, the header files for tools will appear in
the include folder.
The lib folder contains the library files, and CMake adds the pkgconfig
subfolder with the hdf5*.pc files used by the bin/build scripts created by
the CMake build. CMake separates the C interface code from the fortran code by
creating C-stub libraries for each Fortran library. In addition, only CMake
installs the tools library. The names of the szip libraries are different
between the build systems.
The share folder will have the most differences because CMake builds include
a number of CMake specific files for support of CMake's find_package and support
for the HDF5 Examples CMake project.
The issues with the gif tool are:
HDFFV-10592 CVE-2018-17433
HDFFV-10593 CVE-2018-17436
HDFFV-11048 CVE-2020-10809
These CVE issues have not yet been addressed and are avoided by not building
the gif tool by default. Enable building the High-Level tools with these options:
autotools: --enable-hltools
cmake: HDF5_BUILD_HL_TOOLS=ON
