Warning

Keep in mind that Fabric is largely a thin wrapper around Paramiko and Invoke - just because Fabric itself hasn’t had a release in a while doesn’t mean its capabilities aren’t improving! Click those projects’ names in this paragraph to visit their changelogs and see what you might get if you upgrade your dependencies.

2.7.1 2022-07-14

  • [Bug] #1924: (also #2007) Overhaul behavior and testing re: merging together different sources for the key_filename parameter in Connection.connect_kwargs. This fixes a number of type-related errors (string objects have no extend attribute, cannot add lists to strings, etc). Thanks to Joey Dumont, Joseph Conti, and Jared Punzel for the reports; and to Kyle Meyer for submitting an early version of the patch.

2.7.0 2022-03-25

  • [Feature]: Forward local terminal resizes to the remote end, when applicable. (For the technical: this means we now turn SIGWINCH into SSH window-change messages.)

  • [Feature]: Add shell, a belated port of the v1 open_shell() feature.

    • This wasn’t needed initially, as the modern implementation of run is as good or better for full interaction than open_shell() was, provided you’re happy supplying a specific shell to execute.
    • shell serves the corner case where you aren’t happy doing that, eg when you’re speaking to network appliances or other targets which are not typical Unix server environments.
    • Like open_shell(), this new method is primarily for interactive use, and has a slightly less useful return value. See its API docs for more details.

  • [Bug] #2142: Update Connection temporarily so that it doesn’t incidentally apply replace_env=True to local shell commands, only remote ones. On Windows under Python 3.7+, this was causing local commands to fail due to lack of some environment variables. Future updates will cleanly separate the config tree for remote vs local methods.

    Thanks to Bartosz Lachowicz for the report and David JM Emmett for the patch.

  • [Support]: Overhaul administrative metadata and migrate to Circle-CI from Travis-CI.

2.6.0 2021-01-18

  • [Feature] #1999: Add sudo support to Group. Thanks to Bonnie Hardin for the report and to Winston Nolan for an early patchset.

  • [Feature] #1810: Add put/get support to Group.

  • [Feature] #1868: Ported a feature from v1: interpolating the local path argument in Transfer.get with connection and remote filepath attributes.

    For example, cxn.get(remote="/var/log/foo.log", local="{host}/") is now feasible for storing a file in per-host-named directories or files, and in fact Group.get does this by default.

  • [Feature]: When the local path argument to Transfer.get contains nonexistent directories, they are now created instead of raising an error.

    Warning

    This change introduces a new runtime dependency: pathlib2.

  • [Bug]: Fix a handful of issues in the handling and mocking of SFTP local paths and os.path members within fabric.testing; this should remove some occasional “useless Mocks” as well as hewing closer to the real behavior of things like os.path.abspath re: path normalization.

2.5.0 2019-08-06

  • [Feature] #1989: Reinstate command timeouts, by supporting the implementation of that feature in Invoke (pyinvoke/invoke#539). Thanks to Israel Fruchter for report and early patchset.

  • [Feature]: Allow specifying connection timeouts (already available via Connection constructor argument and configuration option) on the command-line, via -t/--connect-timeout.

  • [Feature] #1985: Add support for explicitly closing remote subprocess’ stdin when local stdin sees an EOF, by implementing a new command-runner method recently added to Invoke; this prevents remote programs that ‘follow’ stdin from blocking forever.

  • [Bug]: Anonymous/’remainder’ subprocess execution (eg fab -H host -- command, as opposed to the use of Connection.run inside tasks) was explicitly specifying in_stream=False (i.e. “disconnect from stdin”) under the hood; this was leftover from early development and prevented use of interactive (or other stdin-reading) programs via this avenue.

    It has been removed; cat 'text' | fab -H somehost -- reads-from-stdin (or similar use cases) should work again.

  • [Support]: Removed unnecessary Cryptography version pin from packaging metadata; this was an artifact from early development. At this point in time, only Paramiko’s own direct dependency specification should matter.

    This is unlikely to affect anybody’s install, since Paramiko has required newer Cryptography versions for a number of years now.

  • [Support]: Update minimum Invoke version requirement to >=1.3.

2.4.0 2018-09-13

  • [Feature] #1709: Add Group.close to allow closing an entire group’s worth of connections at once. Patch via Johannes Löthberg.
  • [Feature] #1780: Add context manager behavior to Group, to match the same feature in Connection. Feature request by István Sárándi.
  • [Feature] #1849: Add Connection.from_v1 (and Config.from_v1) for easy creation of modern Connection/Config objects from the currently configured Fabric 1.x environment. Should make upgrading piecemeal much easier for many use cases.

2.3.2 2018-09-13

  • [Bug] #1852: Grant internal Connection objects created during ProxyJump based gateways/proxies a copy of the outer Connection’s configuration object. This was not previously done, which among other things meant one could not fully disable SSH config file loading (as the internal Connection objects would revert to the default behavior). Thanks to Chris Adams for the report.
  • [Bug]: Some debug logging was reusing Invoke’s logger object, generating log messages “named” after invoke instead of fabric. This has been fixed by using Fabric’s own logger everywhere instead.
  • [Bug] #1850: Skip over ProxyJump configuration directives in SSH config data when they would cause self-referential RecursionError (e.g. due to wildcard-using Host stanzas which include the jump server itself). Reported by Chris Adams.
  • [Bug]: Fix a bug preventing tab completion (using the Invoke-level --complete flag) from completing task names correctly (behavior was to act as if there were never any tasks present, even if there was a valid fabfile nearby).

2.2.3 2018-09-13

2.3.1 2018-08-08

  • [Bug]: Update the new functionality added for #1826 so it uses export; without this, nontrivial shell invocations like command1 && command2 end up only applying the env vars to the first command.

2.3.0 2018-08-08

  • [Feature] #1831: Grant Group (and subclasses) the ability to take arbitrary keyword arguments and pass them onto the internal Connection constructors. This allows code such as:

    mygroup = Group('host1', 'host2', 'host3', user='admin')

    which was previously impossible without manually stuffing premade Connection objects into Group.from_connections.

  • [Feature] #1826: Add a new Boolean configuration and Connection parameter, inline_ssh_env, which (when set to True) changes how Fabric submits shell environment variables to remote servers; this feature helps work around commonly restrictive AcceptEnv settings on SSH servers. Thanks to Massimiliano Torromeo and Max Arnold for the reports.

  • [Support] #1653: Clarify Transfer API docs surrounding remote file paths, such as the lack of tilde expansion (a buggy and ultimately unnecessary v1 feature). Thanks to @pint12 for bringing it up.

  • [Support] #1819: Moved example code from the README into the Sphinx landing page so that we could apply doctests; includes a bunch of corrections to invalid example code! Thanks to Antonio Feitosa for the initial catch & patch.

2.2.2 2018-07-31

  • [Bug] #1762: Fix problem where lower configuration levels’ setting of connect_kwargs.key_filename were being overwritten by the CLI --identity flag’s value…even when that value was the empty list. CLI-given values are supposed to win, but not quite that hard. Reported by @garu57.
  • [Bug] #1749: Improve put behavior when uploading to directory (vs file) paths, which was documented as working but had not been fully implemented. The local path’s basename (or file-like objects’ .name attribute) is now appended to the remote path in this case. Thanks to Peter Uhnak for the report.
  • [Bug]: Implement __lt__ on Connection so it can be sorted; this was overlooked when implementing things like __eq__ and __hash__. (No, sorting doesn’t usually matter much for this object type, but when you gotta, you gotta…)
  • [Support] #1653: Clarify Transfer API docs surrounding remote file paths, such as the lack of tilde expansion (a buggy and ultimately unnecessary v1 feature). Thanks to @pint12 for bringing it up.
  • [Support] #1819: Moved example code from the README into the Sphinx landing page so that we could apply doctests; includes a bunch of corrections to invalid example code! Thanks to Antonio Feitosa for the initial catch & patch.

2.1.5 2018-07-31

  • [Bug] #1824: The changes implementing #1772 failed to properly account for backwards compatibility with Invoke-level task objects. This has been fixed; thanks to @ilovezfs and others for the report.
  • [Bug] #1762: Fix problem where lower configuration levels’ setting of connect_kwargs.key_filename were being overwritten by the CLI --identity flag’s value…even when that value was the empty list. CLI-given values are supposed to win, but not quite that hard. Reported by @garu57.

2.2.1 2018-07-18

  • [Bug] #1824: The changes implementing #1772 failed to properly account for backwards compatibility with Invoke-level task objects. This has been fixed; thanks to @ilovezfs and others for the report.

2.2.0 2018-07-13

  • [Feature] #1766: Reinstate support for use as python -m fabric, which (as in v1) now behaves identically to invoking fab. Thanks to @RupeshPatro for the original patchset.

  • [Feature] #1772: @hosts is back – as a @task/Task parameter of the same name. Acts much like a per-task --hosts, but can optionally take dicts of fabric.connection.Connection kwargs as well as the typical shorthand host strings.

    Note

    As of this change, we are now recommending the use of the new-in-this-release Fabric-level @task/Task objects instead of their Invoke counterparts, even if you’re not using the hosts kwarg – it will help future-proof your code for similar feature-adds later, and generally be less confusing than having mixed Invoke/Fabric imports for these object types.

  • [Support]: Updated the minimum required Invoke version to 1.1.

2.1.4 2018-07-13

  • [Bug] #1753: Set one of our test modules to skip user/system SSH config file loading by default, as it was too easy to forget to do so for tests aimed at related functionality. Reported by Chris Rose.
  • [Bug]: The fabric.testing.fixtures.remote pytest fixture was found to not be properly executing expectation/sanity tests on teardown; this was an oversight and has been fixed.

2.0.3 2018-07-13

  • [Bug]: Somehow neglected to actually add extras_require to our setup.py to enable pip install fabric[testing] et al. This has been fixed. We hope.
  • [Bug]: Minor fix to extras_require re: having fabric[pytest] encompass the contents of fabric[testing].
  • [Bug]: Our packages= argument to setuptools.setup was too specific and did not allow for subpackages…such as the newly added fabric.testing. Fixed now.
  • [Bug]: Our packaging metadata lacked a proper MANIFEST.in and thus some distributions were not including ancillary directories like tests and documentation. This has been fixed.

2.1.1 2018-05-24

  • [Bug]: Somehow neglected to actually add extras_require to our setup.py to enable pip install fabric[testing] et al. This has been fixed. We hope.

2.1.0 2018-05-24

  • [Feature]: Exposed our previously internal test helpers for use by downstream test suites, as the fabric.testing subpackage.

    Note

    As this code requires non-production dependencies, we’ve also updated our packaging metadata to publish some setuptools “extras”, fabric[testing] (base) and fabric[pytest] (for pytest users).

  • [Support] #1745: Wrap any imports of invoke.vendor.* with try/except such that downstream packages which have removed invoke.vendor are still able to function by using stand-alone dependencies. Patch courtesy of Othmane Madjoudj.

  • [Support] #1759: Apply the black code formatter to the codebase and engage it on Travis-CI. Thanks to Chris Rose.

  • [Support] #1761: Integration tests were never added to Travis or ported to pytest before 2.0’s release; this has been addressed.

2.0.1 2018-05-14

  • [Bug] #1740: A Python 3 wheel was not uploaded during the previous release as expected; it turned out we were lacking the typical ‘build universal wheels’ setting in our setup.cfg (due to copying it from the one other project in our family of projects which explicitly cannot build universal wheels!) This has been fixed and a proper universal wheel is now built.
