Configuration ============= Configuration file ------------------ Deb-o-Matic configuration file is the most important file within Deb-o-Matic infrastructure. It defines almost every option needed by Deb-o-Matic. It is divided into five sections: ``debomatic``, which contains the general options needed for Deb-o-Matic to work; ``distributions``, which contains all the details related to the distributions Deb-o-Matic can build package for; ``chroots``, which contains the options related to the creation of the chroots used to build packages; ``gpg``, which contains the options related to GPG signature checking; ``modules``, which contains the options related to module handling. Other sections are optionally defined by each single module, their details will be discussed in the :doc:`modules` section. .. CAUTION:: Configuration file must be formatted with `Python ConfigParser`_ syntax. debomatic section ................. This section is mandatory, Deb-o-Matic refuses to start if one of these options is missing from the configuration file. Also, Deb-o-Matic needs to be restarted to pick any change to one of these options. * ``incoming`` This option indicates the directory where Deb-o-Matic expects to find source packages to build, and in which it will store chroots, build logs, and resulting packages. Suggested value: ``/incoming`` .. CAUTION:: Make sure chosen directory exists before launching Deb-o-Matic, otherwise it will refuse to start. * ``architecture`` This option indicates the architecture to build package for. To build packages for the same architecture of the running system, ``system`` can be used instead of specifying the exact one. Suggested value: ``system`` * ``threads`` This option indicates the maximum concurrent builds that can be executed. If more build tasks are scheduled, they will be blocked until a slot becomes available again. More concurrent builds require more CPU cycles, so you may want to try different configurations to fit your needs. ``threads`` takes an integer as parameter. Suggested value: ``3`` * ``inotify`` This option indicates whether to enable inotify support, or not. inotify will notify Deb-o-Matic about the availability of a new task, and will immediately start a new thread according to the requested task. If ``python3-pyinotify`` is not available, Deb-o-Matic will fall back to a timer-based method, where new tasks will be analyzed periodically. ``inotify`` takes True or False as parameter. Suggested value: ``True`` * ``sleep`` This option indicates the number of seconds between two consecutive checks for new packages or commands to process. This option is only useful if inotify support is disabled, or is not available. ``sleep`` takes an integer as parameter. Suggested value: ``60`` * ``interval`` This option indicates the number of seconds between two consecutive triggers for scheduled actions performed by modules. ``interval`` takes an integer as parameter. Suggested value: ``3600`` * ``logfile`` This option indicates which file will be used to store information and warning messages issued by Deb-o-Matic during its execution. Suggested value: ``/var/log/debomatic.log`` * ``loglevel`` This option indicates which kind of debug messages will be displayed. There are four levels: ``error``, ``warning``, ``info``, and ``debug``. Suggested value: ``info`` distributions section ..................... This section is mandatory, Deb-o-Matic refuses to start if one of these options is missing from the configuration file. Also, Deb-o-Matic needs to be restarted to pick any change to one of these options. * ``list`` This option indicates the path of the distribution configuration file. More on those files will be discussed in the `Distributions file section`_. Suggested value: ``/etc/debomatic/distributions`` .. CAUTION:: Make sure chosen directory exists before launching Deb-o-Matic, otherwise it will refuse to start. * ``blacklist`` This option indicates a list of distributions that are not allowed to accept new packages to build. Files targeted for a blacklisted distribution will be automatically deleted. Option must define a space-separated distribution names matching the ones listed in the `Distributions file section`_. Suggested value: ``(blank field)`` * ``mapper`` This option indicates a list of distributions that, even if they are not defined by a distribution file (see `Distributions file section`_), can build packages on top of another distribution. This is particularly useful to indicate distribution aliases (such as ``sid <=> unstable``) or subsets (such as ``vivid-proposed => vivid``). Option must define a `Python dictionary`_ where keys are the distributions indicated by the packages, and values are the distributions on which build packages upon. Suggested value: ``{'sid': 'unstable'}`` chroots section ............... This section is mandatory, Deb-o-Matic refuses to start if one of these options is missing from the configuration file. Also, Deb-o-Matic needs to be restarted to pick any change to one of these options. * ``commands`` This option indicates the directory where sbuild commands are stored. Commands are executable scripts which are processed by sbuild during various build phases. Please refer to the sbuild (1) man page for additional details. At the moment, Deb-o-Matic provides a script to disable Internet connection within the chroot on Linux systems to avoid accessing remote resources during the build phase, and another one to increase the speed of unpacking of the dependencies in the chroots. Suggested value: ``/usr/share/debomatic/sbuildcommands`` .. CAUTION:: This directory needs to be bind mounted in the chroot for the scripts to be launched correctly. It is possible to do so by adjusting the sbuild configuration file. crossbuild section .................. This section is optional, Deb-o-Matic will start normally if this section is missing in the configuration file. Also, Deb-o-Matic needs to be restarted to pick any change to one of these options. * ``crossbuild`` This option indicates whether to enable cross-build support, or not. * ``hostarchitecture`` This option indicates which host architecture to use when building source packages. .. CAUTION:: The architecture must have cross-compilation at compiler lever, otherwise it will not be possible to cross-compile source packages. dpr section ........... This section is optional, Deb-o-Matic will start normally if this section is missing in the configuration file. Also, Deb-o-Matic needs to be restarted to pick any change to one of these options. * ``dpr`` This option indicates whether to enable private repositories, or not. Suggested value: ``False`` * ``prefix`` This option indicates the common prefix of all private repositories. Suggested value: ``dpr`` * ``repository`` This option indicates the APT string of a local APT repository which is added at build time, useful in combination with the Repository module. The string must contain two ``%%(dist)s`` arguments which allows to specify dynamically the private repository name, for example: *deb http://debomatic.repository/debomatic/%%(dist)s %%(dist)s main* gpg section ........... This section is mandatory, Deb-o-Matic refuses to start if one of these options is missing from the configuration file. Also, Deb-o-Matic needs to be restarted to pick any change to one of these options. ``gnupg`` package is required for these options to be effective. * ``gpg`` This option indicates whether to enable signature checking support, or not. If enabled, Deb-o-Matic will delete unsigned files and files with signatures not available in its keyring. ``gpg`` takes True or False as parameter. Suggested value: ``False`` * ``keyring`` This option indicates the gnupg keyring file in which Deb-o-Matic will look for valid and trusted GPG keys. Suggested value: ``/etc/debomatic/debomatic.gpg`` .. CAUTION:: Make sure keyring file exists and is populated with trusted keys if GPG support is enabled, otherwise no tasks will be processed. modules section ............... This section is mandatory, Deb-o-Matic refuses to start if one of these options is missing from the configuration file. Also, Deb-o-Matic needs to be restarted to pick any change to one of these options. More on modules handling will be discussed in the :doc:`modules` section. * ``modules`` This option indicates whether to enable module loading, or not. ``modules`` takes True or False as parameter. Suggested value: ``True`` * ``path`` This option indicates the directory where Deb-o-Matic expects to find modules. Multiple directories can be listed, separated with a colon (``:``). Suggested value: ``/usr/share/debomatic/modules`` * ``threads`` This option indicates how many modules Deb-o-Matic should launch in parallel. ``threads`` takes an integer as parameter. Suggested value: ``5`` * ``blacklist`` This option indicates a list of modules that are not allowed to be executed during build process. Option must define a space-separated module names matching the ones listed in the :doc:`modules` section. Suggested value: ``AutoPkgTest Blhc Lintian Mailer Piuparts`` Distributions file ------------------ This file is populated by sections, each of them named after a distribution to build packages for. Every section can define five options. * ``suite`` This option indicates the base suite to create the chroot for. Normally, it is equal to its distribution, but there are some exceptions (for instance, experimental's suite is unstable). This option is mandatory. * ``mirror`` This option indicates the mirror site which contains the primary package archive of the distribution. This option is mandatory. * ``components`` This option contains a space-delimited list of components to use. This option is mandatory. * ``extramirrors`` This option indicates additional mirrors to add in the chroot. More than one additional mirror can be defined, separated by a newline. This option is optional. * ``extrapackages`` This option contains a space-delimited list of additional packages to install in the chroot during its creation. This option is optional. ..
