===================
Historical releases
===================
1.5.0 (2017-06-23)
==================
- No changes to 1.5.0a6.
1.5.0a6 (2017-05-29)
====================
- Detect "no change" when using long revision ids in `mercurial.Clone()`.
1.5.0a5 (2017-05-21)
====================
- Fix `git.Clone()` verification of local state, so it only updates from remove
if necessary. (#26117)
1.5.0a4 (2017-03-30)
====================
- Add `Component.log()` method to easily put out messages during configure/verify/update.
1.5.0a3 (2017-03-09)
====================
- Improve error reporting in multi host environments.
1.5.0a2 (2017-03-09)
====================
- Change `data-` attribute API to a simple dictionary. This is much more Python like.
1.5.0a1 (2017-03-07)
====================
- Add `data-` attributes to host sections.
1.4.0 (2017-03-06)
==================
- Minor readability improvement for the parallel connection code. changed yet.
1.4.0b7 (2016-12-14)
====================
- `batou.lib.mysql.User` and `batou.lib.mysql.Grant` use `hostname` for the
MySQL *server* and `allow_from_hostname` for granting the client access from.
1.4.0b6 (2016-12-14)
====================
- Fix setting mysql password
1.4.0b5 (2016-12-14)
====================
- `batou.lib.mysql.User` wrongly overwrote the `host` attribute. The `host`
attribute is reserved for host a component is configured on. Use
`User(..., hostname=...)` instead.
1.4.0b4 (2016-12-14)
====================
- `batou.lib.mysql.Grant` wrongly overwrote the `host` attribute. The `host`
attribute is reserved for host a component is configured on. Use
`Grant(..., hostname=...)` instead.
1.4.0b3 (2016-12-13)
====================
- Fix update and secrets commands, to be compatible with `--reset`.
- Fix `batou init`.
1.4.0b2 (2016-12-13)
====================
- Fix multiple platforms per environment backward compatibility: honor global
platform definition.
1.4.0b1 (2016-12-13)
====================
- Support multiple platforms per environment (#12405).
- added --reset switch to batou
- Added a way to customize how supervisor is started on different platforms via
`start()` on a Service platform component.
1.3.5 (2016-12-06)
==================
- Fix installation of batou egg with recend setuptools version (#25089)
1.3.4 (2016-11-25)
==================
- Fix for "make virtualenv files writable" (#24427)
1.3.3 (2016-11-25)
==================
- Git: Clean workingcopy before merging changes.
1.3.2 (2016-11-02)
==================
- Make virtualenv files writable before delete. On systems like NixOS the files
copied by virtualenv are read-only, hence `rm -rf` cannot remove them (#24427)
1.3.1 (2016-10-13)
==================
- Bug fix: Don't update virtualenv on each run. (#23983)
1.3.0 (2016-09-12)
==================
- Update virtualenv when the Python version changes (#22805)
- Remove support for virtualenv with Python 2.4, 2.5 and 3.2.
- Add way to set arbitrary environment variables in crontab.
- Fix performance issue with git and mercurial Clone components.
1.3b3 (2016-05-30)
==================
- Fix a crash in case of GnuPG2 is not installed at all.
1.3b2 (2016-05-27)
==================
- Parallelize connect to remote hosts and bootstrapping of remote batou via
`./batou deploy`.
- Support remote host/port for MySQL commands.
- Copy virtualenv files instead of symlinking (for Python 2.7 and up).
Symlinking breaks especially on NixOS since the symlinks point directly to
the store.
- Hide passwords from output of the `Download` component.
- Add `dependencies` to `supervisor.Program`.
- Fix disconnect error in consistency check.
- Support gpg2.
- Download virtualenv via PIP. This fixes an error caused by the PyPI
restructuring
1.3b1 (2016-03-09)
==================
- Provided extended prediction support for deployments. In addition to ``-c``
which checks internal consistency of the configuration model you can pass
``-P`` which causes verification to be run and predict which changes
will be applied when deploying.
- Enhance support for multi-line members in secret files: order them and
indent them automatically. (#13040)
1.2 (2016-01-29)
================
- Change default of supervisor PID file path to ensure it does something
useful out of the box.
It's still a good idea to place it on a temporary filesystem that is wiped
after a reboot to ensure the PID is from a current system environment.
1.2b2 (2016-01-29)
==================
- Remove the deprecated 'remote' command alias.
- Remove implicit dependency of Supervisor to Logrotation and Nagios.
Supervisor now has the options ``logrotate`` and ``nagios`` that can
be enabled per environment.
**Compatibility note:** if you update from an existing setup with supervisor
you should add this to your environments that actually use those features::
[component:supervisor]
logrotate = True
nagios = True
Otherwise environments will complain that the RotatedLogFile and
nagios.Service have unsatisfied resource requirements. Alternatively you
can drop the ``logrotate`` and ``nrpehost`` or ``nagiosserver`` components
in environments where you don't need them.
1.2b1 (2016-01-28)
==================
- Add more utilities for managing secrets: get an overview of
all environments and what user keys are there, automatically
add or remove users to all, one, or multiple environments.
- Improve component error reporting.
- Add '--check' flag to deploy command. This causes batou to connect only
to the first host and report any configuration errors.
The target will have their batou repository updated, so here's a friendly
reminder that your deployment should not depend on the content of the
repository directly but always only on things copied to the work environment.
- Make the '--fast' and '-F' flags more robust.
- Fix up some outdated examples (not all of them, though).
- Fix configuration error reporting. Removing some code that would
never get run. Do not report configuration errors as deployment errors.
- Display ignored hosts during connection sequence to make numbers add
up and clarify what's going on.
1.1.2 (2016-01-20)
==================
- Improve error reporting for crontab component.
- Fix error ordering.
- Introduce syntax to disable deployment of hosts and components.
Prefix a hostname with '!' or a component name with '!' to have
it configured but not deployed. This supports temporary adjustments
while keeping a consistent config.
We mark this red in the output because this really needs to be used
carefully.
It replaces the approach in batou 1.0 where one would set up dummy
hosts and use "batou local dev localhost".
1.1.1 (2016-01-11)
==================
- Fix supervisor's buildout dependency to avoid non-convergence of
the pip-installed package.
1.1 (2016-01-03)
================
- Fix Debian supervisor's pid file attribute.
- Update supervisor to 3.2.
1.1.0a12 (2015-11-24)
=====================
- Fix curl initial bootstrap.
- Allow to set the contact group of the Supervisor service check from
the environment::
[component:supervisor]
check_contact_groups = group1, group2
1.1.0a11 (2015-11-24)
=====================
- Allow to set the contact group of the Supervisor service check.
1.1.0a10 (2015-11-11)
=====================
- Sort logfiles for logrotate to avoid superfluous reloading.
1.1.0a9 (2015-10-14)
====================
- Do not implicitly perform attribute conversions when applying overrides.
Due to the behaviour of `hasattr` this shadowed conversion exceptions
and also performed unnecessary computation or network access (e.g. DNS).
1.1.0a8 (2015-10-05)
====================
- Fix default pip arguments for installing packages. This stops rebuilds of
python/buildout components on each run.
- Change default virtualenv download URL to https and use the current FCIO
mirror.
1.1.0a7 (2015-09-18)
====================
- Support Git < 2.0
- Add support for managing Python 3.5 environments.
- Update virtualenv to newest version for Python 2.7+ and all
Python 3 versions.
- Drop support for Python 3.1.
- Update supervisor: 3.0 -> 3.1.3
Includes updated dependencies.
- Make socketpath in supervisor configurable.
- Fix broken Python compatibility tests.
1.1.0a6 (2015-09-17)
====================
- Adjust Git repositories to correctly perform fast-forward
merges.
- Fix Mercurial repository tests that broke without noticing.
- Add end-to-end test for our new error reporting which got a
regression (#17617)
1.1.0a5 (2015-09-09)
====================
- Fix Mercurial repositories after refactorings for Git broke it.
1.1.0a4 (2015-09-06)
====================
- Actually get pull-based Git repositories to work. Still experimental, though.
1.1.0a3 (2015-09-05)
====================
- Initial support for managing batou projects with git. Git repositories
support pull-based and bundle-based shipping.
- Add backwards compatibility for `batou remote` to help users
migrate their fingers.
1.1.0a2 (2015-09-03)
====================
- Fix updating from Batou 1.0
1.1.0a1 (2015-09-03)
====================
- Do request an update for packages installed from requirements.txt within
the batou environment to help update VCS checkouts that are pinned.
- Clear PYTHONPATH for bootstrapping to avoid accidental interaction with
unclean Python environments.
- Provide '--fast' mode: do not perform bootstrapping.
This is a first step to improve bootstrapping times. The switch is rather dumb but allows us to work a) offline
in some cases and b) develop faster.
- Fix unicode encoding/decoding in File handling. See #14944.
(Ported from 1.0)
- Fold the runner invocation for `local` and `remote` into
a single `deploy` command:
$ ./batou deploy <environment>
By default batou will assume a remote environment. To configure an environment's deployment mode use the `connect_method` attribute in the `environment` section::
[environment]
connect_method = local
- Improve bootstrapping to give developers a better way
to get started without installing batou system-wide
or in a temporary virtualenv.
- Revamp README and documentation.
- Rework error handling and output management.
batou will now show more errors at once, suppress unnecessary internal tracebacks and try to prioritize
different errors to make complex failure situations
easier to ingest.
1.0.2 (2015-02-27)
==================
- Fix a bundle shipping issue: incorrect language settings caused us to
incorrectly parse the list of heads on the remote side.
1.0.1 (2015-02-26)
==================
- Add virtualenv metadata for Python 2.4
- Keep trailing newlines when rendering templates
1.0 (2015-02-10)
================
- Add 'connect_method = vagrant' to the environment if you want to deploy
into vagrant and use the 'vagrant ssh' invocation.
- Update internal buildout, setuptools, and execnet versions.
- Add 'update_method = rsync' to provide a simple, non-VCS specific way
of shipping batou definitions to the remote side. This does not perform
any conflict resolution and is mainly intended for use with vagrant.
- Supervisor: Assert that a Program should get to state "RUNNING" within
``startsecs`` after restarting, instead of only waiting for ``startsecs``.
1.0b33 (2015-01-28)
===================
- Fix bug in git Clone: Directly after cloning there is nothing to merge,
so don't attempt to.
1.0b32 (2015-01-22)
===================
- Fix custom MySQL admin user when executing SQL statements.
1.0b31 (2015-01-16)
===================
- Rename a variable in ServiceCheck that conflicted with NRPEService and
prevented custom naming of NRPE checks.
1.0b30 (2015-01-09)
===================
- A special case in error reporting caused `batou local` to exit silently
on an error.
- Provide an easier to read error message when encountering non-converging
working sets.
- Provide an easier to read error message when encountering cycles
in the component dependencies.
- Fix bug in git Clone that caused breakage during update() when a fixed
revision was specified.
1.0b29 (2014-12-12)
===================
- Make target directory on remote side configurable via
Environment.target_directory (default is ``~/deployment``).
- Improve installation documentation w.r.t more specific instructions for
various Linux distributions (deb- and rpm-based).
- Change mode of files before changing content to allow self-fixing broken
modes.
- Allow deleting symlinks (on OS X) if they point to directorys.
1.0b28 (2014-10-10)
===================
- batou bootstrap script is more roboust now for cases where the virtualenv becomes
broken.
1.0b27 (2014-09-15)
===================
- Do not configure environments locally when running remote deployments. Use
order as determined by one reference remote host. #13530
- Nagios configuration now supports contact groups.
1.0b26 (2014-08-05)
===================
- Enhance git Clone component to support the full suite of functionality the
mercurial one has (incoming/outgoing/local changes etc.).
NOTE: This changes ``batou.lib.git.Clone`` in backward-incompatible ways:
1. The namevar is now only the ``url``. The previously also accepted usage
of passing the ``target`` as the namevar no longer works.
2. ``update_unpinned`` is gone, use the ``branch``/``revision``/``vcs_update``
mechanism instead.
1.0b25 (2014-07-31)
===================
- Improve gpg handling: don't do --no-tty or --batch any longer as we actually
only run the gpg code in (local) terminal environments usually.
1.0b24 (2014-07-04)
===================
- Actually fix unzipping.
- Remove environment option ``connect_method``, and use autodetection instead:
If we're not the configured ``service_user`` after the plain ssh connect,
run sudo.
- Refactor attributes and overrides: attributes allow template expansion now
and also converting default values. The Attribute class has moved to the
batou component module.
- Yield nonzero returncode on remote exceptions.
- Add convenience converter for attributes "list" to handle comma separated
lists of strings.
- Force safety of Nagios service description field: prohibit "," as its not
safe for Nagios business processes.
- Allow specifying custom rsync options for SyncDir: the '--inplace' option
is a good idea in most cases, but not all. Fixes #11846.
- Make supervisor restart/reload more robust towards non-running supervisors
with lying PID files. Fixes #12744.
- Remove harmful decoding step in File verify that caused wrong results.
1.0b23 (2014-06-30)
===================
- Allow unzip to overwrite existing files if the archive has newer copies.
1.0b22 (2014-06-30)
===================
- Fix uncaught import-error on mysql module.
1.0b21 (2014-06-30)
===================
- Fix bug in bundle shipping that made batou depend on the locale (#13465).
- Add MySQL components.
- Introduce batou.utils.Attribute() to avoid imperative type conversions in
configure().
1.0b20 (2014-05-13)
===================
- Start using python-requests for HTTP/S downloads to support authentication
(and other goodies).
- Improve error logging.
1.0b19 (2014-04-07)
===================
- Allow specifying alternate find-links in requirements.txt
- Remove remnants of the buildout component's ``extends`` option.
1.0b18 (2014-03-31)
===================
- Introduce environment option ``connect_method``, either 'ssh+sudo' (default)
or plain 'ssh'.
- Improve update code: existing installations would not update cleanly to a new
version due to wrong use of pkg_resources API.
Existing installations need to be cleaned manually. :/
- Archive: recognize ``.tar.xz`` files and extract them with ``tar``.
- Fix bug in CMMI verify that would always raise UpdateNeeded due to a path
mismatch (#13145).
- Component.cmd() now performs expand() on the given command by
default. Saves typing:
self.cmd('rm -rf {{component.workdir}}')
instead of
self.cmd(self.expand('rm -rf {{component.workdir}}'))
- File component: apply character encoding when reading and writing files.
(#13165)
- Mercurial clone: changed update behaviour yet again: unless configured
differently, always achieve target state, even by losing uncommitted changes.
- Allow unnamed access to the last added/ored component using the
'self._' attribute:
def configure(self):
self += Download(...)
self += Extract(self._.target)
1.0b17 (2013-12-06)
===================
- Mercurial clone: refuse to update if there are uncommitted changes or
outgoing changesets.
- Mercurial clone: added an option to avoid updating existing clones, which is
often desirable during development.
1.0b16 (2013-11-29)
===================
- Improve the bootstrap/upgrade fix for #13049: the bootstrap template needed a
second improvement.
1.0b15 (2013-11-29)
===================
- Try to fix #13049 - will only work once the dev version is already at least
at b15. Not sure whether it really does the job, though. Hard to test.
- Make environment and host arguments for running ``batou local`` optional.
``dev`` and ``localhost`` are the defaults now. Fixes #13034
- Allow specifying secrets with [component:xy] in addition to [xy] to make it
easier to discover when used to the environment overrides. Both options are
supported now. Fixes #13003
- Refactor Python virtualenv and package management. Provide explicit knowledge
about Python versions 2.4, 2.5, 2.6, 2.7, 3.1, 3.2, and 3.3 to use compatible
virtualenv/pip/setuptools versions and commands. Fixes #12941
NOTE: The API for batou.lib.python.Package has changed in
backwards-incompatible ways:
Package() needs to be added to a VirtualEnv component. Before::
self += VirtualEnv(...)
self += Package(...)
Now::
venv = VirtualEnv(...)
self += venv
venv += Package(...)
Package parameter ``pip_install_options`` has been renamed to
``install_options``.
- Use ``urllib`` module instead of ``wget`` command for cross platform
compatibility.
1.0b14 (2013-11-26)
===================
- Make Buildout component install zc.buildout without dependencies (which is
just setuptools), since that can break the version pinning of setuptools.
- Check whether packages required via a ``-e`` expression in the local
``requirements.txt`` are already installed.
- #12946: Make full path to python executable configurable for virtualenv
(and buildout) component.
- Remove cleanup code that removes batou-0.2-style virtualenv directories (bin,
lib, include etc.) from remote deployments.
- Add mailto setting to crontab component.
- Added some documentation.
1.0b13 (2013-11-19)
===================
- Introduce a plugin mechanism: if a local ``requirements.txt`` file is
present, install its contents into the ``.batou`` virtualenv.
- Load components in alphabetical order. This enables importing from other
components (when naming the directories appropriately).
- #12986: Only try to unbundle if there actually are changes to unbundle.
- Raise an error if a cron job is configured without a timing value.
- Add platform support for Debian (crontab, logrotate, supervisor).
- Added some documentation.
1.0b12 (2013-11-04)
===================
- Added ``branch`` argument to ``mercurial.Clone``. Setting a branch
automatically updates to the branch head on deploy. This is mostly useful for
development environments.
- Create the 'secrets' directory if it doesn't exist, yet. Also, disallow
editing secret files for non-existing environments.
- Support continuing remote bootstrapping if we failed after creating the
initial remote directory but were unable to use Mercurial.
- #12898: build.Configure component was broken when using the default
prefix.
1.0b11 (2013-10-17)
===================
- #12897: Use non-SSL pypi mirror for downloading virtualenv to fix tests
failing randomly on machines that (for some reason) can't validate PyPI's
certificate.
- #12911: Ensure that we can configure file owners when they don't
exist during configure phase yet.
- #12912: Fix untested and broken file ownership management.
- #12847: Clean up unicode handling for File and Content components and
templating.
- #12910: Remote deployments failed when using bundles for transfers if no
changes needed bundling.
- #12766: Allow bootstrapping a batou project in an existing directory to
support migration from 0.2.
- #12283: Recognize files as 'is_template' by default. Auto-detect source files
in the definition directory if they have the same basename. This is what you
want in 99% of all cases. Explicitly stating either the 'content' or 'source'
parameter disables auto-detection.
Now you can write this:
File('foo')
and have `components/x/foo` recognized as the source file and handled as a
template.
- Use ConfigParser instead of configobj which is effectively unmaintained
(see https://twitter.com/voidspace/status/380699699042213889) and support
lists separated by newlines in addition to commas.
1.0b10 (2013-09-27)
===================
- Package our own virtualenv instead of depending on the system-installed one.
This should alleviate troubles due to old virtualenv versions that package
``distribute``, which causes conflicts with recent ``setuptools`` versions
(#12874).
- Update supervisor version to 3.0.
1.0b9 (2013-08-22)
==================
- Update Package component so it ignores installed packages when installing.
This way, we actually install setuptools even when distribute is installed.
(Otherwise it's a no-op since distribute tells pip that setuptools is
already satisfied).
- Fix update process: wrong call to old '.batou/bin/batou' failed and early
bootstrapping would downgrade temporarily which is confusing and superfluous.
Fixes #12739.
1.0b8 (2013-08-17)
==================
- Remove superfluous mkdir call during remote bootstrap.
- Make ``batou init`` print that it's working. Bootstrapping can take a while,
so at least signal that something's going on.
1.0b7 (2013-08-17)
==================
- Depend on Python2.7 to be available on the PATH during early bootstrap.
Otherwise our chances to get a 2.7 virtualenv are pretty small, too.
- Improve project template: ignore the work/ directory by default.
1.0b6 (2013-08-17)
==================
- More MANIFEST inclusions: bootstrap-template.
1.0b5 (2013-08-17)
==================
- Improve MANIFEST so we actually package the init template and other generated
files, like version.txt and requirements.txt.
1.0b4 (2013-08-17)
==================
- Provide a simple project-creation command, both for pip-installed batou's as
well as spawning new projects from existing ones. Fixes #12730
- Fix #12679: make timeouts configurable.
- Removed re-imports from batou main module to support light-weight
self-installation and bootstrapping. I.e. 'from batou import Component' no
longer works.
- Provide a single main command together with a 'bootstrap' wrapper that you
can check into your project and that is maintained during updates
automatically. It also provides fully automatic bootstrapping, installation,
upgrading and other maintenance.
- Fix Python package installation version check.
- Don't use `bin/buildout bootstrap` command anymore. PIP installs a sufficient
`bin/buildout` so buildout can do the rest internally.
- Install zc.buildout during bootstrapping phase using PIP to avoid
bootstrap.py problems.
- Shorten URLs in the Build component to their basename.
- Add 'assert_cmd' API to support simpler assertions for verify when needing to
check the result of an external command.
- Switch to asking pip installing eggs instead of flat installations as
namespaces seem to collide otherwise.
- Remove non-functional deprecated 'md5sum' attribute.
- Components are context managers now. If you provide __enter__ it will be
called before verify() and if you provide __exit__ this will be called after
update (always - even if update isn't actually called). This allows you to
manage temporary state on the target system more gracefully. See the
DMGExtractor for an example.
- Major refactoring of internal data structures to simplify and improve test
coverage. Some breakage to be expected:
* Components do not have a 'service' attribute any longer. If you need access
to the service base directory use 'environment.base_dir'.
- Another attempt at getting convergency for package installation: actually
leverage pkg_resources to check what version of a package is installed. PIP
does not necessarily list or freeze setuptools, even if forced to reinstall.
- Remove superfluous '--update' from pip calls that would temporarily install
the incorrect package version.
- Improve convenience of the 'secrets-edit' wrapper script to allow
re-encrypting without re-entering the editor.
- Consistently switch to using setuptools.
- Fix #12399: incorrect stat attributes for Owner and Group
- Add ``exclude`` parameter to Directory component.
- Add ``env`` parameter to ``Component.cmd()`` (and corresponding
``build_environment`` parameter to the Build component) to allow
adding/overriding environment variables.
1.0b3 (2013-07-09)
==================
- Enable logging in the remote core to see what's going on on the remote side.
- Try to better format exceptions from the remote side.
- Try harder to get virtualenv back into a working state.
- Allow remote deployments from root of repository.
- Make PIP management more robust.
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.
