libpressio version 0.60.0
Major Changes
+ ABI break: the pressio_io_read and related experimental functions no
longer delete or steal the input, but more correctly move the input as
documented. Previously these functions deleted the input value, but
8000
this made it very difficult to safely wrap these functions on platforms
that are garbage collected.
+ BREAKING: the `libpressio` higher-level python binding had several changes to
how it handled configurations:
1. bytes objects are now created as pressio_data objects this is to be
more conistent across the interface and fix some faulty conversions
in SZ-ExaFEL that should have worked
2. mpi4py MPI Communicator objects can now be passed if built with
mpi4py support
3. Several changes to how type-inference works in the python bindings.
For most users, these will just be improvements, and enable a
correct implementation of numcodecs.Codec interface
+ if a template object is NOT passed, we no longer set entires with
a `None` value. This prevents segfaults
+ if a template object is passed, we now only pass the new options
rather than all of the objects from the template.
+ if a template object is passed, we call pressio_options.set_type
if a `None` value is passed with the type from the template.
4. Several default arguments were added to make things default
construable.
5. `name` parameters are now only passed if they are truthy
6. get_configurations was renamed get_compile_config() to be more
consistently and understandably named
7. get_config() now returns a dict which can be directly passed to
`from_configuration` and things should just work
8. Similar changes were made to PressioIO
+ A pretty substantial rewrite to how external_forkexec reads from its
child process to use `select` to be more efficient and avoid deadlocks in
poorly behaved (segfaulting) child processes.
Minor Changes
+ pressio_data::dimensions now returns a const reference
+ better debugging output in the external metric test cases
Bug Fixes
+ fixed a case where the constructor to pressio_data would segfault if
passed a nullptr
+ fixed a number of segfaults when using distributed_manager (i.e.
many_indepenent/many_dependent/etc...) when building with C++11 caused
by constructing with an empty initializer list instead of compat::nullopt
+ fixed a number of compilation failures in the JSON bindings that
incorrectly were implemented in C++17.
+ pinned the version of gtest to avoid build failures in anticipation of
them adding an abseil dependency.
libpressio version 0.58.0
Major Changes
+ Bug fixes requiring an ABI break/new functions
+ defined missing methods for options for {u,}int{8,16,64}_t in the
C public header
+ pressio_options_set_strings is now more const correct
+ fixed include file for pressio_options_json.h when used for C++ so
that names are extern "C"
libpressio version 0.57.0
Major Changes:
+ BREAKING CHANGE - removed the ftk plugin in favor of using it from the
external metrics plugin. This change reduces complexity and code
duplication between this library and the ftk command line application
this also prevents the frequent internals changes in FTK from breaking
libpressio's build. closes #12
+ libpressio now has JSON support with the following features:
+ pressio_options structures can be serialized to and from JSON. NOTE
when serializing options that use pressio_option_userptr_type are
omitted because by definition they cannot be serialized.
+ external metrics can now read a JSON based format when using the
`external:api=json:1` version. This allows returning complex
datatypes from metrics.
+ an experimental hdf5_filter which provides another way to use
compressors supported with libpressio. The JSON support is used in
serializing options where relevant.
Minor Changes:
+ Moved the python bindings to `tools/swig`
+ Added the ability to not produce man page links and install docs when
documentation is built
+ renamed the imagemagick check to be imagemagick_longlong to more clear
about what it was testing for.
Bug Fixes:
+ Added missing headers to CMakeLists to improve clangd and clion
autocompetion.
+ Fixed all current documentation warnings and compiler warnings
libpressio version 0.56.0
Breaking Change
+ metrics now provide a default implementation of
{begin,end}_{de,}compress_many which defaults to calling
{begin,end}_{de,}compress. This eases some of the implementation of
metrics that support being called from `_many` contexts
+ the default implementation of compress_many now calls compress_impl
instead of compress.
