Changelog

v1.2.0

(2024-06-07)

Bug fixes

• |project| no longer crashes when received EOF or when channel is not explicitly closed -- by :user:`pbrezina`.

  Previously, |project| crashed if channel.recv was called and libssh returned SSH_EOF error. It also crashed on some special occasions where channel was not explicitly closed and the session object was garbage-collected first.

  Related issues and pull requests on GitHub: :issue:`576`.

Features

• Started exposing the SSH_OPTIONS_PUBLICKEY_ACCEPTED_TYPES and SSH_OPTIONS_HOSTKEYS options publicly -- by :user:`Qalthos`.

  Related issues and pull requests on GitHub: :issue:`527`.

• The request_exec() method was added to the Channel class. It exposes an interface for calling the respective low-level C-API of the underlying libssh library -- by :user:`pbrezina`.

  Additionally, the following calls to libssh are now available in the same class: request_exec(), send_eof(), request_send_signal() and is_eof which is exposed as a :py:class:`property`.

Improved documentation

• Fixed spelling of "Connect" in the Session.connect() docstring -- by :user:`donnerhacke`.

  Related issues and pull requests on GitHub: :issue:`474`.

• Added a tip to the :ref:`installation guide <Installing |project|>` on how to set compiler flags when installing from source -- :user:`webknjaz`.

  Related issues and pull requests on GitHub: :issue:`499`.

• Fixed the example of invoking remote commands by using Channel.exec_command() in snippets -- by :user:`pbrezina`.

  Its previously showcased version wasn't functional.

  Related issues and pull requests on GitHub: :issue:`576`.

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. It was only reproducible with pip wheel and was not affecting the pyproject-build users.

  -- by :user:`hroncok` and :user:`webknjaz`

  Related commits on GitHub: :commit:`89c9b3a`.

• From now on, the published distribution package artifacts for the new releases are signed via Sigstore -- by :user:`webknjaz.`

  This is happening as a part of the GitHub Actions CI/CD workflow automation and the signatures are uploaded to the corresponding GitHub Release pages.

  Related commits on GitHub: :commit:`986988a`.

• The platform-specific macOS wheels are now built using the Python interpreter from https://python.org. They are tagged with macosx_10_9 -- by :user:`webknjaz`.

  Related issues and pull requests on GitHub: :issue:`333`.

• The toml build time dependency has been replaced with tomli -- by :user:`webknjaz`.

  The tomli distribution is only pulled in under Python versions below 3.11. On 3.11 and higher, the standard library module :py:mod:`tomllib` is now used instead.

  Related issues and pull requests on GitHub: :issue:`501`.

• Started using the built-in setuptools-scm Git archive support under Python 3.7 and higher -- :user:`webknjaz`.

  Related issues and pull requests on GitHub: :issue:`502`.

• Added support for Python 3.12 -- by :user:`Qalthos`.

  It is now both tested in the CI and is advertised through the Trove classifiers.

  Related issues and pull requests on GitHub: :issue:`532`.

• The Cython build time dependency now has the minimum version of 3.0 under Python 3.12 and higher -- by :user:`webknjaz`.

  The previous versions of Cython are still able to build the project under older Python versions.

  Related issues and pull requests on GitHub: :issue:`540`.

• PEP 660 is now enabled -- :user:`webknjaz`.

  Previously, due to restrictive PEP 517 hook reimports, our in-tree build backend was losing :pep:`non-PEP 517 <517>` hooks implemented in newer versions of setuptools but not the earlier ones. This is now addressed by reexporting everything that setuptools exposes with a wildcard.

  Related issues and pull requests on GitHub: :issue:`541`.

• The setuptools-scm build dependency CI pin was updated to 8.1.0 — this version fixes a date parsing incompatibility introduced by Git 2.45.0 (:gh:`pypa/setuptools_scm#1039 <pypa/setuptools_scm/issues/1038>`, :gh:`pypa/setuptools_scm#1038 <pypa/setuptools_scm/pull/1039>`) -- by :user:`webknjaz`.

  Related issues and pull requests on GitHub: :issue:`538`.

• Added separate changelog fragment types for contributor- and downstream-facing patches -- by :user:`webknjaz`.

  Their corresponding identifiers are contrib and packaging respectively. They are meant to be used for more accurate classification, where one would resort to using misc otherwise.

  Related issues and pull requests on GitHub: :issue:`539`.

• PEP 660 is now enabled -- :user:`webknjaz`.

  This effectively means that the ecosystem-native editable install mode started working properly.

  Related issues and pull requests on GitHub: :issue:`541`.

  Related issues and pull requests on GitHub: :issue:`601`.

• The CI/CD configuration was fixed to allow publishing to PyPI and other targets disregarding the test stage outcome. This used to be a bug in the workflow definition that has now been fixed.
