Asv

------------------

Bug Fixes
^^^^^^^^^

- ``build`` is now the default backend for ``asv`` to install projects. (1387)

------------------

New Features
^^^^^^^^^^^^

- Partially skipped benchmarks will still have their results displayed. (1351)
- ``asv`` will now correctly prepare all the build backend dependencies into
``base_requirements`` and the default ``build_command`` has been modified to
allow fetching from PyPI. (1377)


Bug Fixes
^^^^^^^^^

- The ``asv`` package no longer prepends the script execution directory
unconditionally. Now we check for and remove the path only if it matches the
directory that the runner script resides in. (1346)
- The ``bdist`` wheels no longer include ``benchmarks`` and ``test``. (1349)
- The ``mamba`` plugin works correctly for newer versions (>=1.5) of
``libmambapy`` (1372)
- The ``mamba`` plugin respects the ``MAMBARC`` environment if set, taking
channels and channel priority from the file in the environment variable.
(1373)
- Fixed a bug where ``matrix`` requirements were dropped if an environment file
was specified. (1373)
- ``conda-forge`` is no longer a default channel for ``mamba``. (1373)


Other Changes and Additions
^^^^^^^^^^^^^^^^^^^^^^^^^^^

- ``asv`` now depends on ``virtualenv`` (1379)

------------------

Bug Fixes
^^^^^^^^^

- ``pip`` dependencies in ``environment.yml`` files for the ``mamba`` plugin are
handled correctly (1326)
- ``asv.config.json`` matrix requirements no longer need ``pip+`` set explicitly
for calling the ``pip`` solver for ``virtualenv``
- ``asv`` will now use ``conda_environment_file`` if it exists (1325)

Other Changes and Additions
^^^^^^^^^^^^^^^^^^^^^^^^^^^

- ``asv`` timestamps via ``datetime`` are now Python 3.12 compatible (1331)
- ``asv`` now provides ``asv[virtualenv]`` as an installable target
- ``asv`` now uses Github Actions exclusively for Windows and Linux

------------------

New Features
^^^^^^^^^^^^

- ``asv_runner`` is now used internally, making the addition of custom benchmark
types viable (1287)
- Benchmarks can be skipped, both wholly and in part using new decorators
``skip_benchmark_if`` and ``skip_params_if`` (1309)
- Benchmarks can be skipped during their execution (after setup) by raising
``SkipNotImplemented`` (1307)
- Added ``default_benchmark_timeout`` to the configuration object, can also be
passed via ``-a timeout=NUMBER`` (1308)
- ``ASV_RUNNER_PATH`` can be set from the terminal to test newer versions of
``asv_runner`` (1312)

API Changes
^^^^^^^^^^^

- Removed ``asv dev`` in favor of using ``asv run`` with the right arguments
(1200)
- ``asv run`` and ``asv continuous`` don't implement the ``--strict`` option
anymore, and they will always return a non-zero (i.e. ``2``) exit status if
any benchmark fail.

Bug Fixes
^^^^^^^^^

- Fixed ``install_timeout`` for ``conda`` (1310)
- Fixed handling of local ``pip`` matrix (1312)
- Fixed the deadlock when mamba is used with an environment file. (1300)
- Fixed environment file usage with mamba and recognizes default
``environment.yml``. (1303)

Other Changes and Additions
^^^^^^^^^^^^^^^^^^^^^^^^^^^

- ``mamba`` and ``conda`` use ``environment.yml`` if it exists
- ``virtualenv`` now requires ``packaging`` due to ``distutils`` deprecations
(1240)
- Wheels are now built for CPython ``3.8, 3.9, 3.10, 3.11``

------------------

Bug Fixes
^^^^^^^^^

- Packaging ``requirements-dev.txt`` file, used in ``setup.py``. (1013)

----------------

New Features
^^^^^^^^^^^^

- Adding environment variables to build and benchmark commands. (809, 833)
- Added ``--strict`` option to ``asv run`` to set exit code on failure. (865)
- Added ``--no-stats`` option to ``asv compare`` and ``asv continuous``. (879)
- Added ``--durations`` option to ``asv run`` and ``asv show`` for displaying
benchmark run durations. (838)
- Added ``--date-period`` option to ``asv run`` for running benchmarks for
commits separated by a constant time interval. (835)
- Web UI button to group regressions by benchmark. (869)
- Space-saving v2 file format for storing results. (847)
- ``timeraw_*`` benchmarks for measuring e.g. import times. (832)
- Support for using conda environment files for env setup. (793)

API Changes
^^^^^^^^^^^

- Results file format change requires ``asv update`` to update old data to v2
format.
- The configuration syntax for "matrix", "exclude", and "include" in
``asv.conf.json`` has changed. The old syntax is still supported, unless you
are installing packages named ``req``, ``env``, ``env_nobuild``.

Bug Fixes
^^^^^^^^^

- When an ``asv find`` step fails due to timeout, assume runtime equal to
timeout to allow bisection to proceed (768)
- Minor fixes and improvements (897, 896, 888, 881, 877, 876, 875, 861,
870, 868, 867, 866, 864, 863, 857, 786, 854, 855, 852, 850, 844,
843, 842, 839, 841, 840, 837, 836, 834, 831, 830, 829, 828, 826,
825, 824)

Other Changes and Additions
^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Uniqueness of ``repr()`` for ``param`` objects is now guaranteed by suffixing
unique identifier corresponding to order of appearance. (771)
- Memory addresses are now stripped from the ``repr()`` of ``param`` elements,
allowing comparison across multiple runs. (771)
- ``asv dev`` is now equivalent to ``asv run`` with ``--python=same`` default.
(874)
- ``asv continuous`` by default now records measurement samples, for better
comparison statistics. (878)
- ASV now uses PEP 518 ``pyproject.toml`` in packaging. (853)
