Capistrano 3.x Changelog

All notable changes to this project will be documented in this file, in reverse chronological order.

Capistrano follows a modified version of SemVer, similar to the Ruby on Rails project. For a X.Y.Z release:

  • Z indicates bug fixes only; no breaking changes and no new features, except as necessary for security fixes.
  • Y is bumped when we add new features. Occasionally a Y release may include small breaking changes. We will notify via CHANGELOG entries and/or deprecation notices if there are breaking changes.
  • X is incremented for significant breaking changes. This is reserved for special occasions, like a complete rewrite.

Capistrano uses a six-week release cadence. Every six weeks, give or take, any changes in master will be published as a new rubygems version. If you'd like to use a feature or fix that is in master and you can't wait for the next planned release, put this in your project's Gemfile to use the master branch directly:

gem "capistrano", github: "capistrano/capistrano", require: false

master

3.7.0 (2016-12-10)

Note: These release notes include all changes since 3.6.1, including the changes that were first published in 3.7.0.beta1.

Deprecations:

  • The set :scm, ... mechanism is now deprecated in favor of a new SCM plugin system. See the UPGRADING-3.7 document for details

Potentially breaking changes:

  • The :git_strategy, :hg_strategy, and :svn_strategy settings have been removed with no replacement. If you have been using these to customize Capistrano's SCM behavior, you will need to rewrite your customization using the new plugin system
  • remote_file feature has been removed and is no longer available to use @SaiVardhan

New features:

  • The tar used by the Git SCM now honors the SSHKit command map, allowing an alternative tar binary to be used (e.g. gtar) #1787 (@caius)
  • Add support for custom on-filters #1776

Fixes:

  • Fix test suite to work with Mocha 1.2.0 (@caius)
  • Fix bug where host_filter and role_filter were overly greedy #1766 (@cseeger-epages)
  • Fix the removal of old releases deploy:cleanup. Logic is changed because of unreliable modification times on folders. Removal of directories is now decided by sorting on folder names (name is generated from current datetime format YmdHis). Cleanup is skipped, and a warning is given when a folder name is in a different format

3.7.0.beta1 (2016-11-02)

Deprecations:

  • The set :scm, ... mechanism is now deprecated in favor of a new SCM plugin system. See the UPGRADING-3.7 document for details.

Potentially breaking changes:

  • The :git_strategy, :hg_strategy, and :svn_strategy settings have been removed with no replacement. If you have been using these to customize Capistrano's SCM behavior, you will need to rewrite your customization using the new plugin system.
  • remote_file feature has been removed and is no longer available to use @SaiVardhan

New features:

  • The tar used by the Git SCM now honors the SSHKit command map, allowing an alternative tar binary to be used (e.g. gtar) #1787 (@caius)

Fixes:

  • Fix test suite to work with Mocha 1.2.0 (@caius)
  • Fix bug where host_filter and role_filter were overly greedy #1766 (@cseeger-epages)

3.6.1 (2016-08-23)

Fixes:

  • Restore compatibility with older versions of Rake (< 11.0.0) (@troelskn)
  • Fix NoMethodError: undefined method gsub when setting :application to a Proc. The original fix released in 3.6.0 worked for values specified with blocks, but not for those specified with procs or lambdas (the latter syntax is much more common). #1681
  • Fix a bug where deploy would fail if :local_user contained a space; spaces are now replaced with dashes when computing the git-ssh suffix. (@will_in_wi)

3.6.0 (2016-07-26)

Thank you to the many first-time contributors from the Capistrano community who helped with this release!

Deprecations:

  • Deprecate remote_file feature (will be removed in Capistrano 3.7.0) (@lebedev-yury)
  • Deprecate :git_strategy, :hg_strategy, and :svn_strategy variables. These will be completely removed in 3.7.0.
  • Added warning about future deprecation of reinvocation behaviour (@troelskn)

Refer to the Capistrano 3.7.0 upgrade document if you are affected by these deprecations.

New features:

  • Added a doctor:servers subtask that outputs a summary of servers, roles & properties (@irvingwashington)
  • Make path to git wrapper script configurable (@thickpaddy)
  • Make name of current directory configurable via configuration variable :current_directory (@websi)
  • It is now possible to rollback to a specific release using the ROLLBACK_RELEASE environment variable. #1155 (@lanrion)

Fixes:

  • doctor no longer erroneously warns that :git_strategy and other SCM options are "unrecognized" (@shanesaww)
  • Fix NoMethodError: undefined method gsub when setting :application to a Proc. #1681 (@mattbrictson)

Other changes:

  • Raise a better error when an ‘after’ hook isn’t found (@jdelStrother)
  • Change git wrapper path to work better with multiple users (@thickpaddy)
  • Restrict the uploaded git wrapper script permissions to 700 (@irvingwashington)
  • Add net-ssh gem version to doctor:gems output (@lebedev-yury)

3.5.0

You'll notice a big cosmetic change in this release: the default logging format has been changed to Airbrussh. For more details on what Airbrussh does and how to configure it, visit the Airbrussh README.

  • To opt out of the new format, simply add set :format, :pretty to switch to the old default of Capistrano 3.4.0 and earlier.
  • If you are already an Airbrussh user, note that the default configuration has changed, and the syntax for configuring Airbrussh has changed as well. This simple upgrade guide will walk you through it.

Potentially breaking changes:

  • Drop support for Ruby 1.9.3 (Capistrano does no longer work with 1.9.3)
  • Git version 1.6.3 or greater is now required
  • Remove 'vendor/bundle' from default :linked_dirs (@ojab)
  • Old versions of SSHKit (before 1.9.0) are no longer supported
  • SHA1 hash of current git revision written to REVISION file is no longer abbreviated
  • Ensure task invocation within after hooks is namespace aware, which may require you to change how your after hooks are declared in some cases; see #1652 for an example and how to correct it (@thickpaddy)
  • Validation of the :application variable forbids special characters such as slash, this may be a breaking change in case that you rely on using a / in your application name to deploy from a sub directory.

New features:

  • Added a doctor task that outputs helpful troubleshooting information. Try it like this: cap production doctor. (@mattbrictson)
  • Added a dry_run? helper method
  • remove DSL method for removing values like from arrays like linked_dirs
  • append DSL method for pushing values like linked_dirs #1447, #1586
  • Added support for git shallow clone
  • Added new runtime option --print-config-variables that inspect all defined config variables in order to assist development of new capistrano tasks (@gerardo-navarro)
  • Prune dead tracking branches from git repositories while updating
  • Added options to set username and password when using Subversion as SCM (@dsthode)
  • Allow after() to refer to tasks that have not been loaded yet (@jcoglan)
  • Allow use "all" as string for server filtering (@theist)
  • Print a warning and abort if "load:defaults" is erroneously invoked after capistrano is already loaded, e.g. when a plugin is loaded in deploy.rb instead of Capfile. (@mattbrictson)
  • Added option to set specific revision when using Subversion as SCM (@marcovtwout)
  • Deduplicate list of linked directories
  • Integration with Harrow.io (See http://capistranorb.com/documentation/harrow/) when running cap install
  • Added validate method to DSL to allow validation of certain values (@Kriechi)
    • validate values before assignment inside of set(:key, value)
    • should raise a Capistrano::ValidationError if invalid
  • Added default validation for Capistrano-specific variables (@Kriechi)

Fixes:

  • Capistrano is now fully-compatible with Rake 11.0. (@mattbrictson)
  • Fix filtering behaviour when using literal hostnames in on() block (@townsen)
  • Allow dot in :application name (@marcovtwout)
  • Fixed git-ssh permission error (@spight)

Other changes:

  • Internal Rubocop cleanups.
  • Removed the post-install message (@Kriechi)
  • Refactor Configuration::Filter to use filtering strategies instead of case statements (@cshaffer)
  • Clean up rubocop lint warnings (@cshaffer)

3.4.0

  • Fixed fetch revision for annotated git tags. (@igorsokolov)

  • Fixed updating roles when custom user or port is specified. (@ayastreb)

  • Disables statistics collection.

  • bin/ is not suggested to be in linked_dirs anymore (@kirs)

  • Bugfix:

    • release_roles did not honour additional property filtering (@townsen)
    • Refactored and simplified property filtering code (@townsen)

  • Breaking Changes

    • Hosts with the same name are now consolidated into one irrespective of the user and port. This allows multiple declarations of a server to be made safely. The last declared properties will win. See capistranorb.com Properties documentation for details.
    • Inside the on() block the host variable is now a copy of the host, so changes can be made within the block (such as dynamically overriding the user) that will not persist. This is very convenient for switching the SSH user temporarily to 'root' for example.

  • Minor changes

    • Add role_properties() method (see capistrano.github.io PR for doc) (@townsen)
    • Add equality syntax ( eg. port: 1234) for property filtering (@townsen)
    • Add documentation regarding property filtering (@townsen)
    • Clarify wording and recommendation in stage template. (@Kriechi)
      • Both available syntaxes provide similar functionality, do not use both for the same server+role combination.
    • Allow specification of repo_path using stage variable default is as before (@townsen)

3.3.5

  • Fixed setting properties twice when creating new server. See issue #1214 (@ayastreb)

3.3.4

  • Minor changes:
    • Rely on a newer version of capistrano-stats with better privacy (@leehambley)
    • Fix cucumber spec for loading tasks from stage configs (@sponomarev)
    • Minor documentation fixes (@deeeki, @seuros, @andresilveira)
    • Spec improvements (@dimitrid, @sponomarev)
    • Fix to CLI flags for git-ls-remote (@dimitrid)

3.3.3

  • Enhancement (@townsen)

    • Added the variable :repo_tree which allows the specification of a sub-tree that will be extracted from the repository. This is useful when deploying a project that lives in a subdirectory of a larger repository. Implemented only for git and hg. If not defined then the behaviour is as previously and the whole repository is extracted (subject to git-archive .gitattributes of course).

  • Enhancement (@townsen): Remove unnecessary entries from default backtrace

    When the --backtrace (or --trace) command line option is not supplied Rake lowers the noise level in exception backtraces by building a regular expression containing all the system library paths and using it to exclude backtrace entries that match.

    This does not always go far enough, particularly in RVM environments when many gem paths are added. This commit reverses that approach and only include backtrace entries that fall within the Capfile and list of tasks imported thereafter. This makes reading exceptions much easier on the eye.

    If the full unexpurgated backtrace is required then the --backtrace and --trace options supply it as before.

  • Disable loading stages configs on cap -T (@sponomarev)

  • Enhancements (@townsen)

    • Fix matching on hosts with custom ports or users set

    • Previously filtering would affect any generated configuration files so that files newly deployed would not be the same as those on the hosts previously deployed (and now excluded by filters). This is almost certainly not what is wanted: the filters should apply only to the on() method and thus any configuration files deployed will be identical across the set of servers making up the stage.

    • Host and Role filtering now affects only on() commands and not the roles(), release_roles() and primary() methods.

    • This applies to filters defined via the command line, the environment and the :filter variable.

    • Filtering now supports Regular expressions

    • This change could cause existing scripts that use filtering and depend on the old behaviour to fail, though it is unlikely. Users who rely on filtering should check that generated configuration files are correct, and where not introduce server properties to do the filtering. For example, if a filter was used to specify an active subset of servers (by hostname), it should be removed and replaced with an 'active' property (set to true or false) on the server definitions. This keeps the stage file as the canonical model of the deployment environment.

    • See the documentation in the README.md file

  • Enhancements (@townsen)

    • Added set_if_empty method to DSL to allow conditional setting

    • Altered standard Capistrano defaults so that they are not set at the start of a stage if they have been previously set. This allows variables like :default_env to be set in deploy.rb.

    • Deep copy properties added using the 'roles' keyword

    • If a property exists on a server when another definition is encountered and is an Array, Set or Hash then add the new values

      This allows roles to specify properties common to all servers and then for individual servers to modify them, keeping things DRY

Breaking Changes:

  • By using Ruby's noecho method introduced in Ruby version 1.9.3, we dropped support for Ruby versions prior to 1.9.3. See issue #878 and PR #1112 for more information. (@kaikuchn)

  • Track (anonymous) statistics, see https://github.com/capistrano/stats. This breaks automated deployment on continuous integration servers until the .capistrano/metrics file is created (with content full to simulate a "yes") via the interactive prompt or manually.

  • Bug Fixes:

    • Fixed compatibility with FreeBSD tar (@robbertkl)
    • remote_file can be used inside a namespace (@mikz)

  • Minor Changes

    • Remove -v flag from mkdir call. (@caligo-mentis)
    • Capistrano now allows to customize local_user for revision log. (@sauliusgrigaitis)
    • Added tests for after/before hooks features (@juanibiapina, @miry)
    • Added --force flag to svn export command to fix errors when the release directory already exists.
    • Improved the output of cap --help. (@mbrictson)
    • Cucumber suite now runs on the latest version of Vagrant (@tpett)
    • The ask method now supports the echo: false option. (@mbrictson, @kaikuchn)
    • Cucumber scenario improvements (@bruno-)
    • Added suggestion to Capfile to use 'capistrano-passenger' gem, replacing suggestion in config/deploy.rb to re-implement 'deploy:restart' (@betesh)
    • Updated svn fetch_revision method to use svnversion
    • cap install no longer overwrites existing files. (@dmarkow)

3.2.1

  • Bug Fixes:

    • 3.2.0 introduced some behaviour to modify the way before/after hooks were called, to allow the optional preservation of arguments to be passed to tasks. This release reverts that commit in order to restore original functionality, and fix (fairly serious) bugs introduced by the refactoring.

  • Minor changes:

    • Update dsl#local_user method and add test for it. (@bruno-)
    • Revert short sha1 revision with git. (@blaugueux)
    • Changed asking question to more standard format (like common unix commandline tools) (@sponomarev)
    • Fixed typos in the README. (@sponomarev)
    • Added keys method to Configuration to allow introspection of configuration options. (@juanibiapina)
    • Improve error message when git:check fails (raise instead of silently exit 1) (@mbrictson)

3.2.0

The changelog entries here are incomplete, because many authors choose not to be credited for their work, check the tag comparison link for Github.

  • Minor changes:
    • Added keys method to Server properties to allow introspection of automatically added properties.
    • Compatibility with Rake 10.2.0 - ensure_task is now added to @top_level_tasks as a string. (@dmarkow)
    • Amended the git check command, "ls-remote", to use "-h", limiting the list to refs/heads

3.1.0

Breaking changes:

  • deploy:restart task is no longer run by default. From this version, developers who restart the app on each deploy need to declare it in their deploy flow (eg after 'deploy:publishing', 'deploy:restart') or, for passenger applications, use the capistrano-passenger gem.

    Please, check https://github.com/capistrano/capistrano/commit/4e6523e1f50707499cf75eb53dce37a89528a9b0 for more information. (@kirs)

  • Minor changes

    • Tasks that used linked_dirs and linked_files now run on all roles, not just app roles (@mikespokefire)
    • Tasks deploy:linked_dirs, deploy:make_linked_dirs, deploy:linked_files, deploy:cleanup_rollback, deploy:log_revision and deploy:revert_release now use release_roles() not roles() meaning that they will only run on servers where the no_release property is not falsy. (@leehambley)
    • Fixed bug when deploy:cleanup was executed twice by default (@kirs)
    • Config location can now be changed with deploy_config_path and stage_config_path options (@seenmyfate)
    • no_release option is now available (@seenmyfate)
    • Raise an error if developer tries to define :all role, which is reserved (@kirs)
    • deploy:failed hook was added to add some custom behaviour on failed deploy (@seenmyfate)
    • Correctly infer namespace in task enhancements (@seenmyfate)
    • Add SHA to revision log (@blackxored)
    • Allow configuration of multiple servers with same hostname but different ports (@rsslldnphy)
    • Add command line option to control role filtering (@andytinycat)
    • Make use of recent changes in Rake to over-ride the application name (@shime)
    • Readme corrections (@nathanstitt)
    • Allow roles to be fetched with a variable containing an array (@seenmyfate)
    • Improve console (@jage)
    • Add ability to filter tasks to specific servers (host filtering). (@andytinycat)
    • Add a command line option to control role filter (--roles) (@andytinycat)
    • Use an SCM object with a pluggable strategy (@coffeeaddict)

Big thanks to @Kriechi for his help.

3.0.1

  • capify not listed as executable (@leehambley)
  • Confirm license as MIT (@leehambley)
  • Move the git ssh helper to application path (@mpapis)

3.0.0

If you are coming here to wonder why your Capfile doesn't work anymore, please vendor lock your Capistrano at 2.x, whichever version was working for you until today.

Capistrano 3 is a ground-up rewrite with modularity, stability, speed and future proofing in mind. It's a big change, but now the code is 10x smaller, runs faster, is easier to read, and quicker to extend. In the reduction we've come up with a great gem based modular system for plugins and we're really proud of this release.

The 3.0.0 release contains 38 patches from the following amazing people:

  • Tom seenmyfate Clements: more than 28 patches including cucumber integration tests! Not to mention Rails asset pipeline code, and bundler integrations.

  • Lee Hambley: Small changes around compatibility and log formatting

  • Kir Shatrov: for improvements in the core to make it easier to write extensions, for improving documentation, and for effectively building the chruby, rvm and rbenv integrations.

  • Michael Nikitochkin: Fixing a bug around linked files and directories.

  • Jack Thorne: for improvements to the default Capfile to fix some bad example syntax.

  • Erik Hetzner: for (what looks like great) work on the Mercurial (Hg) support. The Hg and Git source control mechanisms do not work the same way, but rather lean on the strengths of the underlying tools.

    (If I missed anyone, I'm sorry, your contributions have been awesome)

The 2.x branch of code is now no longer maintained. Towards the end of it's useful life there were an increasing number of features and pieces of code which didn't make sense for certain groups of people, in certain situations, leading a to a ping-pong tennis effect with pull requests every few weeks "fixing" a use-case which had already been "fixed" shortly before. As many of the use-cases are outside the scope of the testing environments I (and by extension the trusted contributors and IRC regulars) were able to test for.

There's a more extensive post about my failure to be able to keep up with the demands of maintaining v2 whilst trying to build something which is appropriate for the current landscape. If you are affected by the unsupported 2 branch, please contact me (Lee Hambley) to discuss how my company can help support you. Otherwise, please try v3, we're sure you'll like it, and the code is designed to be so simple that anyone can work on it.
