batou 1.0b2

A utility for automating multi-host, multi-environment software builds and deployments.

batou

batou is a multi-(component|host|environment|…) deployment utility.

Deployments are described in a model using “components” and can be deployed locally and remotely. Models are written as Python code.

See the batou documentation for details on how to use it.

Changelog

1.0b2 (2013-07-09)

• Add component to manage PIP within a virtual env.

• Add component to manage packages with PIP within a virtual env.

• Restructure buildout component to make it more robust regarding setuptools/distribute preparation. Also remove usage of bootstrap completely as we rely on virtualenv anyway.

1.0b1 (2013-07-09)

• Apply semantic versioning: initial development is over, so this is 1.0 now.

• Major revamp of secrets management:

  • switch to GPG (instead of aespipe)

  • turn secrets into a core feature, removing the need for a special component

• Add ‘–single’ to suppress parallel bootstrapping.

0.2.9 (2013-07-06)

• Fix #12527: utils.cmd breaks on spacey arguments and embedded quotes.

• Avoid accidentally creating incorrect directories in developer VFS mapping.

• Switch testrunner to pytest. Refactor some tests to take advantage of its capabilities.

• Clean up PEP8 / pyflakes errors, integrate pytest plugin to ensure continued compliance.

• Clean up buildout versions specifications.

• Fix .dmg extractor to copy symlinks as symlinks.

• Fix remote sudo for Mac OS X target hosts.

0.2.8 (2013-06-18)

• Added archive extractor for .dmg files.

• Added flag for supervisor to control whether global or individual restarts wait until everything is running.

0.2.7 (2013-05-22)

• Fix template for Nagios check service dependencies.

• Update bootstrap call for batou-internal bootstrapping.

0.2.6 (2013-05-18)

• Add component that clones from a Mercurial repository.

• Write supervisord.pid into /run/local instead of ${workdir}/var to ensure correct startup after machine crashes.

• Add ignore_returncode parameter to Component.cmd() to suppress exceptions on unsuccessful command execution.

0.2.5 (2013-04-23)

• Fix interaction between supervisor programs and disabled supervisors: don’t try to start those programs.

0.2.4 (2013-04-22)

• Force reread/update on supervisor after config changes.

0.2.3 (2013-04-22)

• supervisor: wait up to 60 seconds instead of 30 until supervisor responds to a PID after triggering shutdown. Fix bug trying to detect shutdown: RuntimeError would cause residual data in output variables.

• supervisor: after reloading, wait as long as the highest startup delay was configured on a program to avoid subsequent accidental restarts.

• supervisor: remove ‘restart’ flag: always restart if we have a relevant change.

• supervisor: fix bug in reload logic: path to supervisord.conf was wrong

0.2.2 (2013-04-19)

• Allow specifying ‘configure_args’ on cmmi.Build or ‘args’ on cmmi.Configure.

• Fix supervisor’s path lookup for event listeners to support the automatically installed superlance plugins better. This may change again in the future depending on other event listener needs.

0.2.1 (2013-04-18)

• Fix supervisor refactoring: templates contained static paths from my development machine. Event listeners were not formatting the event list correctly.

• Let RunningSupervisor wait (infinitely) long when reloading if the supervisorctl command returns ‘SHUTDOWN_STATE’. This supports large installations with many services more gracefully but might get stuck.

• Fix supervisor’s Nagios check: I removed the bin/py custom interpreter and didn’t notice it was used by the check. Put it back.

0.2 (2013-04-18)

• Lots of stuff that went on unreleased for way too long. Producing a release to allow people to stop running from trunk.

• Buildout component: Allow custom buildout.cfg names and pass the name to bootstrap.

• Improve SSH connection error logging: more readable now and hosts are identifiable. (#12093)

• Do not automatically add missing SSH host keys any longer. (#11606)

• Use python version specific virtualenv, if availble. This helps with ancient Python 2.4 components. For specific virtualenv versions no explicit python executable is passed.

• Internalize download hash handling using hashlib. Allow selection of hash function. (Thanks to Christine Koppelt.)

• Introduce new component modelling approach.

• Start writing documentation.

• Improve error message when download fails due to checksum mismatch.
