Compare Source

==================

Bug fixes

• Stopped dropping trailing slashes in :py:meth:~yarl.URL.joinpath -- by :user:gmacon. (:issue:862, :issue:866)
• Started accepting string subclasses in __truediv__() operations (URL / segment) -- by :user:mjpieters. (:issue:871, :issue:884)
• Fixed the human representation of URLs with square brackets in usernames and passwords -- by :user:mjpieters. (:issue:876, :issue:882)
• Updated type hints to include URL.missing_port(), URL.__bytes__()
  and the encoding argument to :py:meth:~yarl.URL.joinpath
  -- by :user:mjpieters. (:issue:891)

Packaging updates and notes for downstreams

• Integrated Cython 3 to enable building yarl under Python 3.12 -- by :user:mjpieters. (:issue:829, :issue:881)

• Declared modern setuptools.build_meta as the :pep:517 build
  backend in :file:pyproject.toml explicitly -- by :user:webknjaz. (:issue:886)

• Converted most of the packaging setup into a declarative :file:setup.cfg
  config -- by :user:webknjaz. (:issue:890)

• The packaging is replaced from an old-fashioned :file:setup.py to an
  in-tree :pep:517 build backend -- by :user:webknjaz.

  Whenever the end-users or downstream packagers need to build yarl from
  source (a Git checkout or an sdist), they may pass a config_settings
  flag --pure-python. If this flag is not set, a C-extension will be built
  and included into the distribution.

  Here is how this can be done with pip:

  .. code-block:: console

  $ python -m pip install . --config-settings=--pure-python=false
  

  This will also work with -e | --editable.

  The same can be achieved via pypa/build:

  .. code-block:: console

  $ python -m build --config-setting=--pure-python=false
  

  Adding -w | --wheel can force pypa/build produce a wheel from source
  directly, as opposed to building an sdist and then building from it. (:issue:893)

  .. attention::

  v1.9.3 was the only version using the --pure-python setting name.
  Later versions dropped the -- prefix, making it just pure-python.

• Declared Python 3.12 supported officially in the distribution package metadata
  -- by :user:edgarrmondragon. (:issue:942)

Contributor-facing changes

• A regression test for no-host URLs was added per :issue:821
  and :rfc:3986 -- by :user:kenballus. (:issue:821, :issue:822)

• Started testing yarl against Python 3.12 in CI -- by :user:mjpieters. (:issue:881)

• All Python 3.12 jobs are now marked as required to pass in CI
  -- by :user:edgarrmondragon. (:issue:942)

• MyST is now integrated in Sphinx -- by :user:webknjaz.

  This allows the contributors to author new documents in Markdown
  when they have difficulties with going straight RST. (:issue:953)
