Release Notes

aio-libs/yarl (yarl)

v1.20.1

======

(2025-06-09)

Bug fixes

• Started raising a :exc:ValueError exception raised for corrupted
  IPv6 URL values.

  These fixes the issue where exception :exc:IndexError was
  leaking from the internal code because of not being handled and
  transformed into a user-facing error. The problem was happening
  under the following conditions: empty IPv6 URL, brackets in
  reverse order.

Packaging updates and notes for downstreams

• Updated to use Cython 3.1 universally across the build path -- by :user:lysnikolaou.

  Related issues and pull requests on GitHub:
  :issue:1514.

• Made Cython line tracing opt-in via the with-cython-tracing build config setting -- by :user:bdraco.

  Previously, line tracing was enabled by default in :file:pyproject.toml, which caused build issues for some users and made wheels nearly twice as slow.
  Now line tracing is only enabled when explicitly requested via pip install . --config-setting=with-cython-tracing=true or by setting the YARL_CYTHON_TRACING environment variable.

(2024-09-04)

Bug fixes

• :meth:URL.join() <yarl.URL.join> has been changed to match
  :rfc:3986 and align with
  :meth:/ operation <yarl.URL.__truediv__> and :meth:URL.joinpath() <yarl.URL.joinpath>
  when joining URLs with empty segments.
  Previously :py:func:urllib.parse.urljoin was used,
  which has known issues with empty segments
  (python/cpython#84774 <https://github.com/python/cpython/issues/84774>_).

  Due to the semantics of :meth:URL.join() <yarl.URL.join>, joining an
  URL with scheme requires making it relative, prefixing with ./.

  .. code-block:: pycon

  URL("https://web.archive.org/web/").join(URL("./https://github.com/aio-libs/yarl"))
  URL('https://web.archive.org/web/https://github.com/aio-libs/yarl')

  Empty segments are honored in the base as well as the joined part.

  .. code-block:: pycon

  URL("https://web.archive.org/web/https://").join(URL("github.com/aio-libs/yarl"))
  URL('https://web.archive.org/web/https://github.com/aio-libs/yarl')

(2024-08-30)

Bug fixes

• Joining URLs with empty segments has been changed
  to match :rfc:3986.

  Previously empty segments would be removed from path,
  breaking use-cases such as

  .. code-block:: python

  URL("https://web.archive.org/web/") / "https://github.com/"

  Now :meth:/ operation <yarl.URL.__truediv__> and :meth:URL.joinpath() <yarl.URL.joinpath>
  keep empty segments, but do not introduce new empty segments.
  e.g.

  .. code-block:: python

  URL("https://example.org/") / ""

  does not introduce an empty segment.

• The default protocol ports of well-known URI schemes are now taken into account
  during the normalization of the URL string representation in accordance with
  :rfc:3986#section-3.2.3.

  Specified ports are removed from the :class:str representation of a :class:~yarl.URL
  if the port matches the scheme's default port -- by :user:commonism.

• :meth:URL.join() <yarl.URL.join> has been changed to match
  :rfc:3986 and align with
  :meth:/ operation <yarl.URL.__truediv__> and :meth:URL.joinpath() <yarl.URL.joinpath>
  when joining URLs with empty segments.
  Previously :py:func:urllib.parse.urljoin was used,
  which has known issues with empty segments
  (python/cpython#84774 <https://github.com/python/cpython/issues/84774>_).

  Due to the semantics of :meth:URL.join() <yarl.URL.join>, joining an
  URL with scheme requires making it relative, prefixing with ./.

  .. code-block:: pycon

  URL("https://web.archive.org/web/").join(URL("./https://github.com/aio-libs/yarl"))
  URL('https://web.archive.org/web/https://github.com/aio-libs/yarl')

  Empty segments are honored in the base as well as the joined part.

  .. code-block:: pycon

  URL("https://web.archive.org/web/https://").join(URL("github.com/aio-libs/yarl"))
  URL('https://web.archive.org/web/https://github.com/aio-libs/yarl')

Packaging updates and notes for downstreams

• A flaw in the logic for copying the project directory into a
  temporary folder that led to infinite recursion when :envvar:TMPDIR
  was set to a project subdirectory path. This was happening in Fedora
  and its downstream due to the use of pyproject-rpm-macros <https://src.fedoraproject.org/rpms/pyproject-rpm-macros>__. It was
  only reproducible with pip wheel and was not affecting the
  pyproject-build users.

Miscellaneous internal changes

• port, scheme, and raw_host are now cached_property -- by :user:bdraco.

  aiohttp accesses these properties quite often, which cause :mod:urllib to build the _hostinfo property every time. port, scheme, and raw_host are now cached properties, which will improve performance.

v1.9.4

Compare Source

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

Bug fixes

• Started raising :py:exc:TypeError when a string value is passed into
  :py:meth:~yarl.URL.build as the port argument -- by :user:commonism.

  Previously the empty string as port would create malformed URLs when rendered as string representations. (:issue:883)

Packaging updates and notes for downstreams

• The leading -- has been dropped from the :pep:517 in-tree build
  backend config setting names. --pure-python is now just pure-python
  -- by :user:webknjaz.

  The usage now looks as follows:

  .. code-block:: console

  $ python -m build \
      --config-setting=pure-python=true \
      --config-setting=with-cython-tracing=true
  

  (:issue:963)

Contributor-facing changes

• A step-by-step :doc:Release Guide <contributing/release_guide> guide has
  been added, describing how to release yarl -- by :user:webknjaz.

  This is primarily targeting maintainers. (:issue:960)

• Coverage collection has been implemented for the Cython modules
  -- by :user:webknjaz.

  It will also be reported to Codecov from any non-release CI jobs.

  To measure coverage in a development environment, yarl can be
  installed in editable mode:

  .. code-block:: console

  $ python -Im pip install -e .
  

  Editable install produces C-files required for the Cython coverage
  plugin to map the measurements back to the PYX-files.

  :issue:961

• It is now possible to request line tracing in Cython builds using the
  with-cython-tracing :pep:517 config setting
  -- :user:webknjaz.

  This can be used in CI and development environment to measure coverage
  on Cython modules, but is not normally useful to the end-users or
  downstream packagers.

  Here's a usage example:

  .. code-block:: console

  $ python -Im pip install . --config-settings=with-cython-tracing=true
  

  For editable installs, this setting is on by default. Otherwise, it's
  off unless requested explicitly.

  The following produces C-files required for the Cython coverage
  plugin to map the measurements back to the PYX-files:

  .. code-block:: console

  $ python -Im pip install -e .
  

  Alternatively, the YARL_CYTHON_TRACING=1 environment variable
  can be set to do the same as the :pep:517 config setting.

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

Bug fixes

• Stopped dropping trailing slashes in :py:meth:~yarl.URL.joinpath -- by :user:gmacon. (:issue:862, :issue:866)
• Started accepting string subclasses in :meth:~yarl.URL.__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)
