=============== Changelog (1.x)

.. note:: This is the changelog for the legacy 1.x version of Fabric. For the current (2.0+) changelog, please see :doc:the main changelog </changelog>.

  • :release:1.15.0 <2022-04-07>

  • :support:- Merge the longstanding fabric3 fork back into our v1 branch so users who'd rather port Fabric 1.x code to Python 3 before upgrading to Fabric 2.x, are able to do so in a "blessed" manner.

    This change includes making sure that the delta between the fork and our v1 branch still functions correctly & passes tests on both interpreters. It also includes a basic CircleCI configuration to test on 3.6, 3.7 and 3.8, not that we expect to be hosting many future commits on this side...

    Major major thanks to Mathias Ertl for his work on the fork, all the contributors on his side of the house during that time, and to Zachary Vance for getting the reconciliation process rolling.

    The changes folded in as part of this work (mostly taken from Mathias' changelog) are as follows:

    • Installation now requires Paramiko 1.17.0 or later.

    • Fix UnicodeDecodeError when receiving remote data.

    • Clean up imports in main code base and test suite.

    • Add Python 2/3/3.5 classifiers in setup.py.

    • Replace fabric.utils.RingBuffer with collections.deque from stdlib.

    • Under Python 3, Fabric implements its own version of contextlib.nested based on contextlib.ExitStack, since it's no longer available in Python3.

      • Please note that it was removed with good reason, we do not encourage you use it.
  • :release:1.14.1 <2018-11-27>

  • :bug:1341 (via :issue:1586) Attempt to rm -f the temporary file used by put's sudo mode, when exceptions are encountered; previously, the internal sudo mv call could potentially fail and leave the file around. Thanks to Andrei Sura for the report and Uku Loskit for the fix.

  • :bug:1242 (via :issue:1243) ~fabric.contrib.project.rsync_project: only supply the -p <number> option to generated rsync commands when the port number differs from the default; this allows removing --rsh entirely most of the time, and thus enables things like using rsync's daemon mode on the remote end. Reported & patched by Arnaud Rocher.

  • :bug:1227 Remove a bash/zsh-ism from ~fabric.contrib.files.upload_template when backing up the target file, preventing issues on simpler remote shells. Patch courtesy of Paul Chakravarti.

  • :bug:983 Move a getpass import inside a Windows-oriented try/except ImportError so password prompting is less likely to explode on certain systems. Thanks to @dongweiming for the patch.

  • :support:- backported Update packaging metadata so wheel archives include the LICENSE file.

  • :release:1.14.0 <2017-08-25>

  • :feature:1475 Honor env.timeout when opening new remote sessions (as opposed to the initial overall connection, which already honored timeout settings.) Thanks to @EugeniuZ for the report & @jrmsgit for the first draft of the patch.

    .. note:: This feature only works with Paramiko 1.14.3 and above; if your Paramiko version is older, no timeout can be set, and the previous behavior will occur instead.

  • :release:1.13.2 <2017-04-24>

  • :release:1.12.2 <2017-04-24>

  • :bug:1542 (via :issue:1543) Catch Paramiko-level gateway connection errors (ChannelError) when raising NetworkError; this prevents an issue where gateway related issues were being treated as authentication errors. Thanks to Charlie Stanley for catch & patch.

  • :bug:1555 Multiple simultaneous ~fabric.operations.get and/or ~fabric.operations.put with use_sudo=True and for the same remote host and path could fail unnecessarily. Thanks @arnimarj for the report and Pierce Lopez for the patch.

  • :bug:1427 (via :issue:1428) Locate .pyc files when searching for fabfiles to load; previously we only used the presence of .py files to determine whether loading should be attempted. Credit: Ray Chen.

  • :bug:1294 fix text escaping for ~fabric.contrib.files.contains and ~fabric.contrib.files.append which would fail if the text contained e.g. >. Thanks to @ecksun for report & Pierce Lopez for the patch.

  • :support:1065 backported Fix incorrect SSH config reference in the docs for env.keepalive; it corresponds to ServerAliveInterval, not ClientAliveInterval. Credit: Harry Percival.

  • :bug:1574 ~fabric.contrib.project.upload_project failed for folder in current directory specified without any path separator. Thanks @aidanmelen for the report and Pierce Lopez for the patch.

  • :support:1590 backported Replace a reference to fab in a test subprocess, to use the python -m <package> style instead; this allows python setup.py test to run the test suite without having Fabric already installed. Thanks to @BenSturmfels for catch & patch.

  • :support:- backported Backport :issue:1462 to 1.12.x (was previously only backported to 1.13.x.)

  • :support:1416 backported Add explicit "Python 2 only" note to setup.py trove classifiers to help signal that fact to various info-gathering tools. Patch courtesy of Gavin Bisesi.

  • :bug:1526 Disable use of PTY and shell for a background command execution within contrib.sed, preventing a small class of issues on some platforms/environments. Thanks to @doflink for the report and Pierce Lopez for the final patch.

  • :support:1539 backported Add documentation for env.output_prefix. Thanks @jphalip.

  • :bug:1514 Compatibility with Python 2.5 was broken by using the format() method of a string (only in 1.11+). Report by @pedrudehuere.

  • :release:1.13.1 <2016-12-09>

  • :bug:1462 Make a PyCrypto-specific import and method call optional to avoid ImportError problems under Paramiko 2.x. Thanks to Alex Gaynor for catch & patch!

  • :release:1.13.0 <2016-12-09>

  • :support:1461 Update setup requirements to allow Paramiko 2.x, now that it's stable and been out in the wild for some time. Paramiko 1.x still works like it always did; the only change to Paramiko 2 was the backend moving from PyCrypto to Cryptography.

    .. warning:: If you are upgrading an existing environment, the install dependencies have changed; please see Paramiko's installation docs for details: http://www.paramiko.org/installing.html

  • :release:1.12.1 <2016-12-05>

  • :release:1.11.3 <2016-12-05>

  • :release:1.10.5 <2016-12-05>

  • :bug:1470 When using fabric.operations.get with glob expressions, a lack of matches for the glob would result in an empty file named after the glob expression (in addition to raising an error). This has been fixed so the empty file is no longer generated. Thanks to Georgy Kibardin for the catch & initial patch.

  • :feature:1495 Update the internals of fabric.contrib.files so its members work with SSH servers running on Windows. Thanks to Hamdi Sahloul for the patch.

  • :support:1483 backported (also re: :issue:1386, :issue:1374, :issue:1300) Add an FAQ about quote problems in remote csh causing issues with Fabric's shell-wrapping and quote-escaping. Thanks to Michael Radziej for the update.

  • :support:1379 backported (also :issue:1464) Clean up a lot of unused imports and similar cruft (many found via flake8 --select E4). Thanks to Mathias Ertl for the original patches.

  • :bug:1458 Detect known_hosts-related instances of paramiko.SSHException and prevent them from being handled like authentication errors (which is the default behavior). This fixes issues with incorrect password prompts or prompt-related exceptions when using reject_unknown_hosts and encountering missing or bad known_hosts entries. Thanks to Lukáš Doktor for catch & patch.

  • :release:1.12.0 <2016-07-25>

  • :release:1.11.2 <2016-07-25>

  • :release:1.10.4 <2016-07-25>

  • :feature:1491 Implement sudo-specific password caching. This can be used to work around issues where over-eager submission of env.password at login time causes authentication problems (e.g. during two-factor auth).

  • :bug:1447 Fix a relative import in fabric.network to be correctly/consistently absolute instead. Thanks to @bildzeitung for catch & patch.

  • :release:1.11.1 <2016-04-09>

  • :bug:- (==1.11) Bumped version to 1.11.1 due to apparently accidentally uploading a false 1.11.0 to PyPI sometime in the past (PyPI is secure & prevents reusing deleted filenames.) We have no memory of this, but databases don't lie!

  • :release:1.11.0 <2016-04-09>

  • :release:1.10.3 <2016-04-09>

  • :bug:1135 (via :issue:1241) Modified order of operations in fabric.operations.run/fabric.operations.sudo to apply environment vars before prefixing commands (instead of after). Report by @warsamebashir, patch by Curtis Mattoon.

  • :feature:1203 (via :issue:1240) Add a case_sensitive kwarg to fabric.contrib.files.contains (which toggles use of egrep -i). Report by @xoul, patch by Curtis Mattoon.

  • :feature:800 Add capture_buffer_size kwarg to fabric.operations.run/fabric.operations.sudo so users can limit memory usage in situations where subprocesses generate very large amounts of stdout/err. Thanks to Jordan Starcher for the report & Omri Bahumi for an early version of the patchset.

  • :feature:1161 Add use_sudo kwarg to fabric.operations.reboot. Credit: Bryce Verdier.

  • :support:943 backported Tweak env.warn_only docs to note that it applies to all operations, not just run/sudo. Thanks @akitada.

  • :feature:932 Add a temp_dir kwarg to fabric.contrib.files.upload_template which is passed into its inner fabric.operations.put call. Thanks to @nburlett for the patch.

  • :support:1257 backported Add notes to the usage docs for fab regarding the program's exit status. Credit: @koalaman.

  • :feature:1261 Expose Paramiko's Kerberos functionality as Fabric config vars & command-line options. Thanks to Ramanan Sivaranjan for catch & patch, and to Johannes Löthberg & Michael Bennett for additional testing.

  • :feature:1271 Allow users whose fabfiles use fabric.colors to disable colorization at runtime by specifying FABRIC_DISABLE_COLORS=1 (or any other non-empty value). Credit: Eric Berg.

  • :feature:1326 Make fabric.contrib.project.rsync_project aware of env.gateway, using a ProxyCommand under the hood. Credit: David Rasch.

  • :support:1359 Add a more-visible top-level CHANGELOG.rst pointing users to the actual changelog stored within the Sphinx directory tree. Thanks to Jonathan Vanasco for catch & patch.

  • :feature:1388 Expose Jinja's keep_trailing_newline parameter in fabric.contrib.files.upload_template so users can force template renders to preserve trailing newlines. Thanks to Chen Lei for the patch.

  • :bug:1389 major Gently overhaul SSH port derivation so it's less surprising; previously, any non-default value stored in env.port was overriding all SSH-config derived values. See the API docs for fabric.network.normalize for details on how it now behaves. Thanks to Harry Weppner for catch & patch.

  • :support:1454 backported Remove use of :option: directives in the changelog, it's currently broken in modern Sphinx & doesn't seem to have actually functioned on Renaissance-era Sphinx either.

  • :bug:1365 (via :issue:1372) Classic-style fabfiles (ones not using @task) erroneously included custom exception subclasses when collecting tasks. This is now fixed thanks to @mattvonrocketstein.

  • :bug:1348 (via :issue:1361) Fix a bug in fabric.operations.get where remote file paths containing Python string formatting escape codes caused an exception. Thanks to @natecode for the report and Bradley Spink for the fix.

  • :release:1.10.2 <2015-06-19>

  • :support:1325 Clarify fabric.operations.put docs re: the mode argument. Thanks to @mjmare for the catch.

  • :bug:1318 Update functionality added in :issue:1213 so abort error messages don't get printed twice (once by us, once by sys.exit) but the annotated exception error message is retained. Thanks to Felix Almeida for the report.

  • :bug:1305 (also :issue:1313) Fix a couple minor issues with the operation of & demo code for the JobQueue class. Thanks to @dioh and Horst Gutmann for the report & Cameron Lane for the patch.

  • :bug:980 (also :issue:1312) Redirect output of cd to /dev/null so users enabling bash's CDPATH (or similar features in other shells) don't have polluted output captures. Thanks to Alex North-Keys for the original report & Steve Ivy for the fix.

  • :bug:1286 (also :issue:971, :issue:1032) Recursively unwrap decorators instead of only unwrapping a single decorator level, when obtaining task docstrings. Thanks to Avishai Ish-Shalom for the original report & Max Kovgan for the patch.

  • :bug:1273 Fix issue with ssh/config not having a cross-platform default path. Thanks to @SamuelMarks for catch & patch.

  • :feature:1200 Introduced exceptions output level, so users don't have to deal with the debug output just to see tracebacks.

  • :support:1239 Update README to work better under raw docutils so the example code block is highlighted as Python on PyPI (and not just on our Sphinx-driven website). Thanks to Marc Abramowitz.

  • :release:1.10.1 <2014-12-19>

  • :release:1.9.2 <2014-12-19>

  • :bug:1201 Don't naively glob all fabric.operations.get targets - only glob actual directories. This avoids incorrectly yielding permission errors in edge cases where a requested file is within a directory lacking the read permission bit. Thanks to Sassa Nf for the original report.

  • :bug:1019 (also :issue:1022, :issue:1186) Fix "is a tty" tests in environments where streams (eg sys.stdout) have been replaced with objects lacking a .isatty() method. Thanks to Miki Tebeka for the original report, Lele Long for a subsequent patch, and Julien Phalip for the final/merged patch.

  • :support:1213 backported Add useful exception message to the implicit SystemExit raised by Fabric's use of sys.exit inside the fabric.api.abort function. This allows client code catching SystemExit to have better introspection into the error. Thanks to Ioannis Panousis.

  • :bug:1228 Update the CommandTimeout class so it has a useful str instead of appearing blank when caught by Fabric's top level exception handling. Catch & patch from Tomaz Muraus.

  • :bug:1180 Fix issue with unicode steam outputs crashing if stream encoding type is None. Thanks to @joekiller for catch & patch.

  • :support:958 backported Remove the Git SHA portion of our version string generation; it was rarely useful & occasionally caused issues for users with non-Git-based source checkouts.

  • :support:1229 backported Add some missing API doc hyperlink references. Thanks to Tony Narlock.

  • :bug:1226 Update fabric.operations.get to ensure that env.user has access to tempfiles before changing permissions. Also corrected permissions from 404 to 0400 to match comment. Patch by Curtis Mattoon; original report from Daniel Watkins.

  • :release:1.10.0 <2014-09-04>

  • :bug:1188 major Update fabric.operations.local to close non-pipe file descriptors in the child process so subsequent calls to fabric.operations.local aren't blocked on e.g. already-connected network sockets. Thanks to Tolbkni Kao for catch & patch.

  • :feature:700 Added use_sudo and temp_dir params to fabric.operations.get. This allows downloading files normally not accessible to the user using sudo. Thanks to Jason Coombs for initial report and to Alex Plugaru for the patch (:issue:1121).

  • :feature:1098 Add support for dict style roledefs. Thanks to Jonas Lundberg.

  • :feature:1090 Add option to skip unknown tasks. Credit goes to Jonas Lundberg.

  • :bug:1147 Use stat instead of lstat when testing directory-ness in the SFTP module. This allows recursive downloads to avoid recursing into symlinks unexpectedly. Thanks to Igor Kalnitsky for the patch.

  • :bug:1146 Fix a bug where fabric.contrib.files.upload_template failed to honor lcd when mirror_local_mode is True. Thanks to Laszlo Marai for catch & patch.

  • :bug:1134 Skip bad hosts when the tasks are executed in parallel. Thanks to Igor Maravić @i-maravic.

  • :bug:1059 Update IPv6 support to work with link-local address formats. Fix courtesy of @obormot.

  • :bug:1026 Fix a typo preventing quiet operation of fabric.contrib.files.is_link. Caught by @dongweiming.

  • :bug:600 Clear out connection caches in full when prepping parallel-execution subprocesses. This avoids corner cases causing hangs/freezes due to client/socket reuse. Thanks to Ruslan Lutsenko for the initial report and Romain Chossart for the suggested fix.

  • :bug:1167 Add Jinja to test_requires in setup.py for the couple of newish tests that now require it. Thanks to Kubilay Kocak for the catch.

  • :release:1.9.0 <2014-06-08>

  • :feature:1078 Add .command and .real_command attributes to local return value. Thanks to Alexander Teves (@alexanderteves) and Konrad Hałas (@konradhalas).

  • :bug:844 Account for SSH config overhaul in Paramiko 1.10 by e.g. updating treatment of IdentityFile to handle multiple values. This and related SSH config parsing changes are backwards incompatible; we are including them in this release because they do fix incorrect, off-spec behavior.

  • :bug:843 Ensure string pool_size values get run through int() before deriving final result (stdlib min() has odd behavior here...). Thanks to Chris Kastorff for the catch.

  • :bug:839 Fix bug in fabric.contrib.project.rsync_project where IPv6 address were not always correctly detected. Thanks to Antonio Barrero for catch & patch.

  • :bug:587 Warn instead of aborting when env.use_ssh_config is True but the configured SSH conf file doesn't exist. This allows multi-user fabfiles to enable SSH config without causing hard stops for users lacking SSH configs. Thanks to Rodrigo Pimentel for the report.

  • :feature:821 Add fabric.context_managers.remote_tunnel to allow reverse SSH tunneling (exposing locally-visible network ports to the remote end). Thanks to Giovanni Bajo for the patch.

  • :feature:823 Add env.remote_interrupt which controls whether Ctrl-C is forwarded to the remote end or is captured locally (previously, only the latter behavior was implemented). Thanks to Geert Jansen for the patch.

  • :release:1.5.3 <2013-01-28>

  • :bug:806 Force strings given to getpass during password prompts to be ASCII, to prevent issues on some platforms when Unicode is encountered. Thanks to Alex Louden for the patch.

  • :bug:805 Update fabric.context_managers.shell_env to play nice with Windows (7, at least) systems and fabric.operations.local. Thanks to Fernando Macedo for the patch.

  • :bug:654 Parallel runs whose sum total of returned data was large (e.g. large return values from the task, or simply a large number of hosts in the host list) were causing frustrating hangs. This has been fixed.

  • :feature:402 Attempt to detect stale SSH sessions and reconnect when they arise. Thanks to @webengineer for the patch.

  • :bug:791 Cast fabric.operations.reboot's wait parameter to a numeric type in case the caller submitted a string by mistake. Thanks to Thomas Schreiber for the patch.

  • :bug:703 major Add a shell kwarg to many methods in fabric.contrib.files to help avoid conflicts with fabric.context_managers.cd and similar. Thanks to @mikek for the patch.

  • :feature:730 Add env.system_known_hosts/--system-known-hosts to allow loading a user-specified system-level SSH known_hosts file. Thanks to Roy Smith for the patch.

  • :feature:818 Added env.eagerly_disconnect option to help prevent pile-up of many open connections.

  • :feature:706 Added env.tasks, returning list of tasks to be executed by current fab command.

  • :bug:766 Use the variable name of a new-style fabric.tasks.Task subclass object when the object name attribute is undefined. Thanks to @todddeluca for the patch.

  • :bug:792 The newish fabric.context_managers.shell_env context manager was incorrectly omitted from the fabric.api import endpoint. This has been remedied. Thanks to Vishal Rana for the catch.

  • :feature:735 Add ok_ret_codes option to env to allow alternate return codes to be treated os "ok". Thanks to Andy Kraut for the pull request.

  • :bug:775 Shell escaping was incorrectly applied to the value of $PATH updates in our shell environment handling, causing (at the very least) fabric.operations.local binary paths to become inoperable in certain situations. This has been fixed.

  • :feature:787 Utilize new Paramiko feature allowing us to skip the use of temporary local files when using file-like objects in fabric.operations.get/fabric.operations.put.

  • :feature:249 Allow specification of remote command timeout value by setting env.command_timeout. Thanks to Paul McMillan for suggestion & initial patch.

  • Added current host string to prompt abort error messages.

  • :release:1.5.1 <2012-11-15>

  • :bug:776 Fixed serious-but-non-obvious bug in direct-tcpip driven gatewaying (e.g. that triggered by -g or env.gateway.) Should work correctly now.

  • :bug:771 Sphinx autodoc helper fabric.docs.unwrap_tasks didn't play nice with @task(name=xxx) in some situations. This has been fixed.

  • :release:1.5.0 <2012-11-06>

  • :release:1.4.4 <2012-11-06>

  • :feature:38 (also :issue:698) Implement both SSH-level and ProxyCommand-based gatewaying for SSH traffic. (This is distinct from tunneling non-SSH traffic over the SSH connection, which is :issue:78 and not implemented yet.)

    • Thanks in no particular order to Erwin Bolwidt, Oskari Saarenmaa, Steven Noonan, Vladimir Lazarenko, Lincoln de Sousa, Valentino Volonghi, Olle Lundberg and Github user @acrish for providing the original patches to both Fabric and Paramiko.
  • :feature:684 backported (also :issue:569) Update how fabric.decorators.task wraps task functions to preserve additional metadata; this allows decorated functions to play nice with Sphinx autodoc. Thanks to Jaka Hudoklin for catch & patch.

  • :support:103 (via :issue:748) Long standing Sphinx autodoc issue requiring error-prone duplication of function signatures in our API docs has been fixed. Thanks to Alex Morega for the patch.

  • :bug:767 major Fix (and add test for) regression re: having linewise output automatically activate when parallelism is in effect. Thanks to Alexander Fortin and Dustin McQuay for the bug reports.

  • :bug:736 major Ensure context managers that build env vars play nice with contextlib.nested by deferring env var reference to entry time, not call time. Thanks to Matthew Tretter for catch & patch.

  • :feature:763 Add --initial-password-prompt to allow prefilling the password cache at the start of a run. Great for sudo-powered parallel runs.

  • :feature:665 (and #629) Update fabric.contrib.files.upload_template to have a more useful return value, namely that of its internal fabric.operations.put call. Thanks to Miquel Torres for the catch & Rodrigue Alcazar for the patch.

  • :feature:578 Add name argument to fabric.decorators.task to allow overriding of the default "function name is task name" behavior. Thanks to Daniel Simmons for catch & patch.

  • :feature:761 Allow advanced users to parameterize fabric.main.main() to force loading of specific fabfiles.

  • :bug:749 Gracefully work around calls to fabric.version on systems lacking /bin/sh (which causes an OSError in subprocess.Popen calls.)

  • :feature:723 Add the group= argument to fabric.operations.sudo. Thanks to Antti Kaihola for the pull request.

  • :feature:725 Updated fabric.operations.local to allow override of which local shell is used. Thanks to Mustafa Khattab.

  • :bug:704 major Fix up a bunch of Python 2.x style print statements to be forwards compatible. Thanks to Francesco Del Degan for the patch.

  • :feature:491 (also :feature:385) IPv6 host string support. Thanks to Max Arnold for the patch.

  • :feature:699 Allow name attribute on file-like objects for get/put. Thanks to Peter Lyons for the pull request.

  • :bug:711 major fabric.sftp.get would fail when filenames had % in their path. Thanks to John Begeman

  • :bug:702 major fabric.operations.require failed to test for "empty" values in the env keys it checks (e.g. require('a-key-whose-value-is-an-empty-list') would register a successful result instead of alerting that the value was in fact empty. This has been fixed, thanks to Rich Schumacher.

  • :bug:718 isinstance(foo, Bar) is used in fabric.main instead of type(foo) == Bar in order to fix some edge cases. Thanks to Mikhail Korobov.

  • :bug:693 Fixed edge case where abort driven failures within parallel tasks could result in a top level exception (a KeyError) regarding error handling. Thanks to Marcin Kuźmiński for the report.

  • :support:681 backported Fixed outdated docstring for fabric.decorators.runs_once which claimed it would get run multiple times in parallel mode. That behavior was fixed in an earlier release but the docs were not updated. Thanks to Jan Brauer for the catch.

  • :release:1.4.3 <2012-07-06>

  • :release:1.3.8 <2012-07-06>

  • :feature:263 Shell environment variable support for fabric.operations.run/fabric.operations.sudo added in the form of the fabric.context_managers.shell_env context manager. Thanks to Oliver Tonnhofer for the original pull request, and to Kamil Kisiel for the final implementation.

  • :feature:669 Updates to our Windows compatibility to rely more heavily on cross-platform Python stdlib implementations. Thanks to Alexey Diyan for the patch.

  • :bug:671 reject-unknown-hosts sometimes resulted in a password prompt instead of an abort. This has been fixed. Thanks to Roy Smith for the report.

  • :bug:659 Update docs to reflect that fabric.operations.local currently honors env.path. Thanks to @floledermann <https://github.com/floledermann>_ for the catch.

  • :bug:652 Show available commands when aborting on invalid command names.

  • :support:651 backported Added note about nesting with statements on Python 2.6+. Thanks to Jens Rantil for the patch.

  • :bug:649 Don't swallow non-abort-driven exceptions in parallel mode. Fabric correctly printed such exceptions, and returned them from fabric.tasks.execute, but did not actually cause the child or parent processes to halt with a nonzero status. This has been fixed. fabric.tasks.execute now also honors env.warn_only so users may still opt to call it by hand and inspect the returned exceptions, instead of encountering a hard stop. Thanks to Matt Robenolt for the catch.

  • :feature:241 Add the command executed as a .command attribute to the return value of fabric.operations.run/fabric.operations.sudo. (Also includes a second attribute containing the "real" command executed, including the shell wrapper and any escaping.)

  • :feature:646 Allow specification of which local streams to use when fabric.operations.run/fabric.operations.sudo print the remote stdout/stderr, via e.g. run("command", stderr=sys.stdout).

  • :support:645 backported Update Sphinx docs to work well when run out of a source tarball as opposed to a Git checkout. Thanks again to @Arfrever for the catch.

  • :support:640 backported (also :issue:644) Update packaging manifest so sdist tarballs include all necessary test & doc files. Thanks to Mike Gilbert and @Arfrever for catch & patch.

  • :feature:627 Added convenient quiet and warn_only keyword arguments to fabric.operations.run/fabric.operations.sudo which are aliases for settings(hide('everything'), warn_only=True) and settings(warn_only=True), respectively. (Also added corresponding context managers.) Useful for remote program calls which are expected to fail and/or whose output doesn't need to be shown to users.

  • :feature:633 Allow users to turn off host list deduping by setting env.dedupe_hosts to False. This enables running the same task multiple times on a single host, which was previously not possible.

  • :support:634 backported Clarified that fabric.context_managers.lcd does no special handling re: the user's current working directory, and thus relative paths given to it will be relative to os.getcwd(). Thanks to @techtonik <https://github.com/techtonik>_ for the catch.

  • :release:1.4.2 <2012-05-07>

  • :release:1.3.7 <2012-05-07>

  • :bug:562 Agent forwarding would error out or freeze when multiple uses of the forwarded agent were used per remote invocation (e.g. a single fabric.operations.run command resulting in multiple Git or SVN checkouts.) This has been fixed thanks to Steven McDonald and GitHub user @lynxis.

  • :support:626 backported Clarity updates to the tutorial. Thanks to GitHub user m4z for the patches.

  • :bug:625 fabric.context_managers.hide/fabric.context_managers.show did not correctly restore prior display settings if an exception was raised inside the block. This has been fixed.

  • :bug:624 Login password prompts did not always display the username being authenticated for. This has been fixed. Thanks to Nick Zalutskiy for catch & patch.

  • :bug:617 Fix the clean_revert behavior of fabric.context_managers.settings so it doesn't KeyError for newly created settings keys. Thanks to Chris Streeter for the catch.

  • :feature:615 Updated fabric.operations.sudo to honor the new setting env.sudo_user as a default for its user kwarg.

  • :bug:616 Add port number to the error message displayed upon connection failures.

  • :bug:609 (and :issue:564) Document and clean up env.sudo_prefix so it can be more easily modified by users facing uncommon use cases. Thanks to GitHub users 3point2 for the cleanup and SirScott for the documentation catch.

  • :bug:610 Change detection of env.key_filename's type (added as part of SSH config support in 1.4) so it supports arbitrary iterables. Thanks to Brandon Rhodes for the catch.

  • :release:1.4.1 <2012-04-04>

  • :release:1.3.6 <2012-04-04>

  • :bug:608 Add capture kwarg to fabric.contrib.project.rsync_project to aid in debugging rsync problems.

  • :bug:607 Allow fabric.operations.local to display stdout/stderr when it warns/aborts, if it was capturing them.

  • :bug:395 Added an FAQ entry detailing how to handle init scripts which misbehave when a pseudo-tty is allocated.

  • :bug:568 fabric.tasks.execute allowed too much of its internal state changes (to variables such as env.host_string and env.parallel) to persist after execution completed; this caused a number of different incorrect behaviors. fabric.tasks.execute has been overhauled to clean up its own state changes -- while preserving any state changes made by the task being executed.

  • :bug:584 fabric.contrib.project.upload_project did not take explicit remote directory location into account when untarring, and now uses fabric.context_managers.cd to address this. Thanks to Ben Burry for the patch.

  • :bug:458 fabric.decorators.with_settings did not perfectly match fabric.context_managers.settings, re: ability to inline additional context managers. This has been corrected. Thanks to Rory Geoghegan for the patch.

  • :bug:499 contrib.files.first used an outdated function signature in its wrapped fabric.contrib.files.exists call. This has been fixed. Thanks to Massimiliano Torromeo for catch & patch.

  • :bug:551 --list output now detects terminal window size and truncates (or doesn't truncate) accordingly. Thanks to Horacio G. de Oro for the initial pull request.

  • :bug:572 Parallel task aborts (as oppposed to unhandled exceptions) now correctly print their abort messages instead of tracebacks, and cause the parent process to exit with the correct (nonzero) return code. Thanks to Ian Langworth for the catch.

  • :bug:306 Remote paths now use posixpath for a separator. Thanks to Jason Coombs for the patch.

  • :release:1.4.0 <2012-02-13>

  • :release:1.3.5 <2012-02-13>

  • :release:1.2.6 <2012-02-13>

  • :release:1.1.8 <2012-02-13>

  • :bug:495 Fixed documentation example showing how to subclass fabric.tasks.Task. Thanks to Brett Haydon for the catch and Mark Merritt for the patch.

  • :bug:410 Fixed a bug where using the fabric.decorators.task decorator inside/under another decorator such as fabric.decorators.hosts could cause that task to become invalid when invoked by name (due to how old-style vs new-style tasks are detected.) Thanks to Dan Colish for the initial patch.

  • :feature:559 fabric.contrib.project.rsync_project now allows users to append extra SSH-specific arguments to rsync's --rsh flag.

  • :feature:138 env.port may now be written to at fabfile module level to set a default nonstandard port number. Previously this value was read-only.

  • :feature:3 Fabric can now load a subset of SSH config functionality directly from your local ~/.ssh/config if env.use_ssh_config is set to True. See ssh-config for details. Thanks to Kirill Pinchuk for the initial patch.

  • :feature:12 Added the ability to try connecting multiple times to temporarily-down remote systems, instead of immediately failing. (Default behavior is still to only try once.) See env.timeout and env.connection_attempts for controlling both connection timeouts and total number of attempts. fabric.operations.reboot has also been overhauled (but practically deprecated -- see its updated docs.)

  • :feature:474 fabric.tasks.execute now allows you to access the executed task's return values, by itself returning a dictionary whose keys are the host strings executed against.

  • :bug:487 major Overhauled the regular expression escaping performed in fabric.contrib.files.append and fabric.contrib.files.contains to try and handle more corner cases. Thanks to Neilen Marais for the patch.

  • :support:532 Reorganized and cleaned up the output of fab --help.

  • :feature:8 Added --skip-bad-hosts/env.skip_bad_hosts option to allow skipping past temporarily down/unreachable hosts.

  • :feature:13 Env vars may now be set at runtime via the new --set command-line flag.

  • :feature:506 A new output alias, commands, has been added, which allows hiding remote stdout and local "running command X" output lines.

  • :feature:72 SSH agent forwarding support has made it into Fabric's SSH library, and hooks for using it have been added (disabled by default; use -A or env.forward_agent to enable.) Thanks to Ben Davis for porting an existing Paramiko patch to ssh and providing the necessary tweak to Fabric.

  • :release:1.3.4 <2012-01-12>

  • :bug:492 @parallel did not automatically trigger linewise output, as was intended. This has been fixed. Thanks to Brandon Huey for the catch.

  • :bug:510 Parallel mode is incompatible with user input, such as password/hostname prompts, and was causing cryptic Operation not supported by device errors when such prompts needed to be displayed. This behavior has been updated to cleanly and obviously abort instead.

  • :bug:494 Fixed regression bug affecting some env values such as env.port under parallel mode. Symptoms included fabric.contrib.project.rsync_project bailing out due to a None port value when run under @parallel. Thanks to Rob Terhaar for the report.

  • :bug:339 Don't show imported fabric.colors members in --list output. Thanks to Nick Trew for the report.

  • :release:1.3.3 <2011-11-23>

  • :release:1.2.5 <2011-11-23>

  • :release:1.1.7 <2011-11-23>

  • :bug:441 Specifying a task module as a task on the command line no longer blows up but presents the usual "no task by that name" error message instead. Thanks to Mitchell Hashimoto for the catch.

  • :bug:475 Allow escaping of equals signs in per-task args/kwargs.

  • :bug:450 Improve traceback display when handling ImportError for dependencies. Thanks to David Wolever for the patches.

  • :bug:446 Add QNX to list of secondary-case fabric.contrib.files.sed targets. Thanks to Rodrigo Madruga for the tip.

  • :bug:443 fabric.contrib.files.exists didn't expand tildes; now it does. Thanks to Riccardo Magliocchetti for the patch.

  • :bug:437 fabric.decorators.with_settings now correctly preserves the wrapped function's docstring and other attributes. Thanks to Eric Buckley for the catch and Luke Plant for the patch.

  • :bug:400 Handle corner case of systems where pwd.getpwuid raises KeyError for the user's UID instead of returning a valid string. Thanks to Dougal Matthews for the catch.

  • :bug:397 Some poorly behaved objects in third party modules triggered exceptions during Fabric's "classic or new-style task?" test. A fix has been added which tries to work around these.

  • :bug:341 fabric.contrib.files.append incorrectly failed to detect that the line(s) given already existed in files hidden to the remote user, and continued appending every time it ran. This has been fixed. Thanks to Dominique Peretti for the catch and Martin Vilcans for the patch.

  • :bug:342 Combining fabric.context_managers.cd with fabric.operations.put and its use_sudo keyword caused an unrecoverable error. This has been fixed. Thanks to Egor M for the report.

  • :bug:482 Parallel mode should imply linewise output; omission of this behavior was an oversight.

  • :bug:230 Fix regression re: combo of no fabfile & arbitrary command use. Thanks to Ali Saifee for the catch.

  • :release:1.3.2 <2011-11-07>

  • :release:1.2.4 <2011-11-07>

  • :release:1.1.6 <2011-11-07>

  • :support:459 backported Update our setup.py files to note that PyCrypto released 2.4.1, which fixes the setuptools problems.

  • :support:467 backported (also :issue:468, :issue:469) Handful of documentation clarification tweaks. Thanks to Paul Hoffman for the patches.

  • :release:1.3.1 <2011-10-24>

  • :bug:457 Ensured that Fabric fast-fails parallel tasks if any child processes encountered errors. Previously, multi-task invocations would continue to the 2nd, etc task when failures occurred, which does not fit with how Fabric usually behaves. Thanks to Github user sdcooke for the report and Morgan Goose for the fix.

  • :release:1.3.0 <2011-10-23>

  • :release:1.2.3 <2011-10-23>

  • :release:1.1.5 <2011-10-23>

  • :release:1.0.5 <2011-10-23>

  • :support:275 To support an edge use case of the features released in :issue:19, and to lay the foundation for :issue:275, we have forked Paramiko into the Python 'ssh' library <https://pypi.org/project/ssh/>_ and changed our dependency to it for Fabric 1.3 and higher. This may have implications for the more uncommon install use cases, and package maintainers, but we hope to iron out any issues as they come up.

  • :bug:323 fabric.operations.put forgot how to expand leading tildes in the remote file path. This has been corrected. Thanks to Piet Delport for the catch.

  • :feature:21 It is now possible, using the new fabric.tasks.execute API call, to execute task objects (by reference or by name) from within other tasks or in library mode. fabric.tasks.execute honors the other tasks' fabric.decorators.hosts/fabric.decorators.roles decorators, and also supports passing in explicit host and/or role arguments.

  • :feature:19 Tasks may now be optionally executed in parallel. Please see the parallel execution docs for details. Major thanks to Morgan Goose for the initial implementation.

  • :bug:182 During display of remote stdout/stderr, Fabric occasionally printed extraneous line prefixes (which in turn sometimes overwrote wrapped text.) This has been fixed.

  • :bug:430 Tasks decorated with fabric.decorators.runs_once printed extraneous 'Executing...' status lines on subsequent invocations. This is noisy at best and misleading at worst, and has been corrected. Thanks to Jacob Kaplan-Moss for the report.

  • :release:1.2.2 <2011-09-01>

  • :release:1.1.4 <2011-09-01>

  • :release:1.0.4 <2011-09-01>

  • :bug:252 fabric.context_managers.settings would silently fail to set env values for keys which did not exist outside the context manager block. It now works as expected. Thanks to Will Maier for the catch and suggested solution.

  • :support:393 backported Fixed a typo in an example code snippet in the task docs. Thanks to Hugo Garza for the catch.

  • :bug:396 --shortlist broke after the addition of --list-format and no longer displayed the short list format correctly. This has been fixed.

  • :bug:373 Re-added missing functionality preventing host exclusion from working correctly.

  • :bug:303 Updated terminal size detection to correctly skip over non-tty stdout, such as when running fab taskname | other_command.

  • :release:1.2.1 <2011-08-21>

  • :release:1.1.3 <2011-08-21>

  • :release:1.0.3 <2011-08-21>

  • :bug:417 abort-on-prompts would incorrectly abort when set to True, even if both password and host were defined. This has been fixed. Thanks to Valerie Ishida for the report.

  • :support:416 backported Updated documentation to reflect move from Redmine to Github.

  • :bug:389 Fixed/improved error handling when Paramiko import fails. Thanks to Brian Luft for the catch.

  • :release:1.2.0 <2011-07-12>

  • :feature:22 Enhanced @task to add aliasing, per-module default tasks, and control over the wrapping task class. Thanks to Travis Swicegood for the initial work and collaboration.

  • :bug:380 Improved unicode support when testing objects for being string-like. Thanks to Jiri Barton for catch & patch.

  • :support:382 Experimental overhaul of changelog formatting & process to make supporting multiple lines of development less of a hassle.

  • :release:1.1.2 <2011-07-07>
