  To install libssh refer to its Downloads page.

Building the module

In the local env, assumes there’s a libssh shared library on the system, build toolchain is present and env vars are set properly:

$ git clone https://github.com/ansible/pylibssh.git
$ cd pylibssh
$ pip install tox
$ tox -e build-dists

manylinux-compatible wheels:

$ git clone https://github.com/ansible/pylibssh.git
$ cd pylibssh
$ pip install tox
$ tox -e build-dists-manylinux1-x86_64  # with Docker

# or with Podman
$ DOCKER_EXECUTABLE=podman tox -e build-dists-manylinux1-x86_64

# to enable shell script debug mode use
$ tox -e build-dists-manylinux1-x86_64 -- -e DEBUG=1

Changelog

v1.3.0

(2025-10-12)

Bug fixes

• The bundled libssh 0.11.2 no longer fails, when the SFTP server announces protocol version 3, but does not provide error message and language tag in the SSH_FXP_STATUS message – by @Jakuje.

  Related issues and pull requests on GitHub: #222.

• Fixed reading files over SFTP that go over the pre-defined chunk size.

  Prior to this change, the files could end up being corrupted, ending up with the last read chunk written to the file instead of the entire payload.

  – by @Jakuje

  Related issues and pull requests on GitHub: #638.

• Repetitive calls to exec_channel() no longer crash and return reliable output – by @Jakuje.

  Related issues and pull requests on GitHub: #658.

• Uploading large files over SCP no longer fails – by @Jakuje.

  Related issues and pull requests on GitHub: #661.

• Improved performance of SFTP transfers by using larger transfer chunks – by @Jakuje.

  Related issues and pull requests on GitHub: #664.

• Fixed crash when more operations were called after session.close() – by @Jakuje.

  Related issues and pull requests on GitHub: #709.

Features

• The underlying SSH_OPTIONS_KEY_EXCHANGE option of libssh is now available as key_exchange_algorithms – by @NilashishC.

  Related issues and pull requests on GitHub: #675.

• Added a pylibsshext.session.connect() parameter open_session_retries – by @justin-stephenson.

  The open_session_retries session connect() parameter allows a configurable number of retries if libssh ssh_channel_open_session() returns SSH_AGAIN. The default option value is 0, no retries will be attempted.

  Related issues and pull requests on GitHub: #756.

• Added a pylibsshext.session.connect() parameter timeout_usec to set SSH_OPTIONS_TIMEOUT_USEC.

  This allows setting the SSH_OPTIONS_TIMEOUT_USEC ssh option, though SSH_OPTIONS_TIMEOUT is a more practical option.

  – by @justin-stephenson

  Related issues and pull requests on GitHub: #756.

Deprecations (removal in next major release)

  – by @webknjaz

  Related issues and pull requests on GitHub: #759.

• A workaround has been applied to the in-tree build backend that prevents Cython from hanging when libssh header files are missing – by @webknjaz.

  Related issues and pull requests on GitHub: #676.

• The dumb-pypi-produced static package index now renders correct URLs to the distribution packages – by @webknjaz.

  Related issues and pull requests on GitHub: #678, #679, #749.

• The CI is now configured to use :external+tox``tox-run—installpkg`` when testing pre-built dists. This replaces the previously existing tox-level hacks in test-binary-dists and test-source-dists environments that have now been removed.

  – by @webknjaz

  Related issues and pull requests on GitHub: #688.

  – by @webknjaz

  – by @webknjaz

  Related issues and pull requests on GitHub: #706.

• The linting is now configured to check schemas of the Read The Docs configuration file and the GitHub Actions CI/CD workflow files in addition to enforcing timeouts.

  – by @webknjaz

• The host OS is now ARM-based when building manylinux_*_*_aarch64 images for CI/CD – by @webknjaz.

  Related issues and pull requests on GitHub: #731.

• False negative warnings reported by coveragepy when are now disabled. They are evident when pytest-cov runs with the pytest-xdist integration. pytest 8.4 gives them more visibility and out filterwarnings = error setting was turning them into errors before this change.

  – by @webknjaz

  Related issues and pull requests on GitHub: #732.

• GitHub Actions CI/CD no longer runs jobs that install source distributions into the tox environments for testing – by @webknjaz.

  This is a temporary workaround for an upstream bug in tox and said jobs are non-essential.

  – by @webknjaz

  Related issues and pull requests on GitHub: #759.

• The requires setting has been removed from tox.ini, which works around the upstream tool bug. This enabled us to re-introduce CI jobs testing against sdist under Python 3.12 and newer – by @webknjaz.

v1.2.0

(2024-06-07)

Bug fixes

• ansible-pylibssh no longer crashes when received EOF or when channel is not explicitly closed – by @pbrezina.

  Previously, ansible-pylibssh 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: #576.

Features

• Started exposing the SSH_OPTIONS_PUBLICKEY_ACCEPTED_TYPES and SSH_OPTIONS_HOSTKEYS options publicly – by @Qalthos.

  Related issues and pull requests on GitHub: #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 @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 property.

  Related issues and pull requests on GitHub: #576.

Improved documentation

• Fixed spelling of “Connect” in the Session.connect() docstring – by @donnerhacke.

  Related issues and pull requests on GitHub: #474.

  Its previously showcased version wasn’t functional.

  Related issues and pull requests on GitHub: #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 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 @hroncok and @webknjaz

  Related commits on GitHub: 89c9b3a.

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

  Related issues and pull requests on GitHub: #333.

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

  Related issues and pull requests on GitHub: #540.

• PEP 660 is now enabled – @webknjaz.

  Previously, due to restrictive PEP 517 hook reimports, our in-tree build backend was losing non-PEP 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: #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 (GitHub: pypa/setuptools_scm#1038, GitHub: pypa/setuptools_scm#1039) – by @webknjaz.

  Related issues and pull requests on GitHub: #601.

  Related issues and pull requests on GitHub: #539.

• PEP 660 is now enabled – @webknjaz.

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

  Related issues and pull requests on GitHub: #541.
