 Triggers
 ^^^^^^^^

-Triggers are extensions which can be used in order to perform any actions after the update process. The package provides two default extensions - one is report generation and another one is remote upload feature.
+Triggers are extensions which can be used in order to perform any actions on application start, after the update process and, finally, before the application exit. The package provides two default extensions - one is report generation and another one is remote upload feature.

 The main idea is to load classes by their full path (e.g. ``ahriman.core.upload.UploadTrigger``) by using ``importlib``: get the last part of the import and treat it as class name, join remain part by ``.`` and interpret as module path, import module and extract attribute from it.

 The loaded triggers will be called with ``ahriman.models.result.Result`` and ``List[Packages]`` arguments, which describes the process result and current repository packages respectively. Any exception raised will be suppressed and will generate an exception message in logs.

+In addition triggers can implement ``on_start`` and ``on_stop`` actions which will be called on the application start and right before the application exit. The ``on_start`` action is usually being called from handlers directly in order to make sure that no trigger will be run when it is not required (e.g. on user management). As soon as ``on_start`` action is called, the additional flag will be set; ``ahriman.core.triggers.TriggerLoader`` class implements ``__del__`` method in which, if the flag is set, the ``on_stop`` actions will be called.
+
 For more details how to deal with the triggers, refer to :doc:`documentation <triggers>` and modules descriptions.

 Before using this command you will need to create local directory, put ``PKGBUILD`` there and generate ``.SRCINFO`` by using ``makepkg --printsrcinfo > .SRCINFO`` command. These packages will be stored locally and *will be ignored* during automatic update; in order to update the package you will need to run ``package-add`` command again.

+Err, I have remote repository with PKGBUILDs and would like to get versions from there automatically
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For that purpose you could use ``RemotePullTrigger`` trigger. To do so you will need:
+
+#.
+   Append ``triggers`` option in ``build`` section with the following line:
+
+   .. code-block:: ini
+
+      [build]
+      triggers = ahriman.core.gitremote.RemotePullTrigger
+
+#.
+   Configure trigger as following:
+
+   .. code-block:: ini
+
+      [gitremote]
+      pull_url = https://github.com/username/repository
+
+During the next application run it will fetch repository from the specified url and will try to find packages there which can be used as local sources.
+
+I would like to push PKGBUILDs to the remote repository

+
+For that purpose you'd need to use another trigger called ``RemotePushTrigger``. Configure it as following:

+Unlike ``RemotePullTrigger`` trigger, the ``RemotePushTrigger`` more likely will require authorization. It is highly recommended to use application tokens for that instead of using your password (e.g. for Github you can generate tokens `here <https://github.com/settings/tokens>`_ with scope ``public_repo``). Authorization can be supplied by using authorization part of the url, e.g. ``https://key:token@github.com/username/repository``.

+Well it is supported also. The recommended way is to patch specific function, e.g. by running ``sudo -u ahriman ahriman patch-add ahriman version``. This command will prompt for new value of the PKGBUILD variable ``version``. You can also write it to file and read from it ``sudo -u ahriman ahriman patch-add ahriman version version.patch``.
+
+Alternatively you can create full-diff patches, which are calculated by using ``git diff`` from current PKGBUILD master branch:

 #. Clone sources from AUR.
 #. Make changes you would like to (e.g. edit ``PKGBUILD``, add external patches).
-#. Run ``sudo -u ahriman ahriman patch-add /path/to/local/directory/with/PKGBUILD``.
+#. Run ``sudo -u ahriman ahriman patch-set-add /path/to/local/directory/with/PKGBUILD``.

 The last command will calculate diff from current tree to the ``HEAD`` and will store it locally. Patches will be applied on any package actions (e.g. it can be used for dependency management).

 Triggers
 ========

-The package provides ability to write custom extensions which will be run on (the most) actions, e.g. after updates.

+The package provides ability to write custom extensions which will be run on (the most) actions, e.g. after updates. By default ahriman provides three types of extensions - reporting, files uploading and PKGBUILD syncronization. Each extension must derive from the ``ahriman.core.triggers.Trigger`` class and should implement at least one of the abstract methods:
+
+* ``on_result`` - trigger action which will be called after build process, the build result and the list of repository packages will be supplied as arguments.
+* ``on_start`` - trigger action which will be called right before the start of the application process.
+* ``on_stop`` - action which will be called right before the exit.
+
+Note, it isn't required to implement all of those methods (or even one of them), however, it is highly recommended to avoid trigger actions in ``__init__`` method as it will be run on any application start (e.g. even if you are just searching in AUR).
+
+Built-in triggers
+-----------------
+
+For the configuration details and settings explanation kindly refer to the :doc:`documentation <configuration>`.
+
+``ahriman.core.gitremote.RemotePullTrigger``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This trigger will be called before any action (``on_start``) and pulls remote PKGBUILD repository locally; after that it copies found PKGBUILDs from the cloned repository to the local cache. It is useful in case if you have patched PGKBUILDs (or even missing in AUR) which you would like to use for package building and, technically, just simplifies the local package building.
+
+In order to update those packages you would need to clone your repository separately, make changes in PKGBUILD (e.g. bump version and update checksums), commit them and push back. On the next ahriman's repository update, it will pull changes you commited and will perform package update.
+
+``ahriman.core.gitremote.RemotePushTrigger``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This trigger will be called right after build process (``on_result``). It will pick PKGBUILDs for the updated packages, pull them (together with any other files) and commit and push changes to remote repository. No real use cases, but the most of user repositories do it.
+
+``ahriman.core.report.ReportTrigger``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Trigger which can be used for reporting. It implements ``on_result`` method and thus being called on each build update and generates report (e.g. html, telegram etc) according to the current settings.
+
+``ahriman.core.upload.UploadTrigger``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This trigger takes build result (``on_result``) and performs syncing of the local packages to the remote mirror (e.g. S3 or just by rsync).

 Trigger example
 ---------------

-Lets consider example of reporting trigger (e.g. `slack <https://slack.com/>`_, which provides easy HTTP API for integration triggers).

Author	SHA1	Message	Date
Evgeniy Alekseev	d98211e5e5	add possibility to run full update In case if packages are not set from web, the spawner will run full repository update	2022-10-31 02:41:24 +02:00
Evgeniy Alekseev	b97c8928e1	add daemon subcommand This command emulates default systemd timer and can be useful in docker container in order to run 24/7	2022-10-31 01:38:01 +02:00
Evgenii Alekseev	649df81aa5	implement single-function patches (#69 )	2022-10-30 03:11:03 +03:00
Evgeniy Alekseev	ad7cdb7d95	drop ahriman.core.triggers.Trigger.run method In order to force new triggers to use on_result method, the old method has been removed. However, default on_result method still checks if the old method exists and tries to run it	2022-10-19 20:07:31 +03:00
Evgeniy Alekseev	4bb598d2eb	fix rtd docs building Commit `6633766cc3` introduced kw_only dataclasess which require python 3.10+	2022-10-18 02:24:18 +03:00
Evgeniy Alekseev	f47be6cab0	disallow no values in configuration This option could lead to missing warnings about missing or invalid configuration values because code usually expects that values are exists and not empty unless it is explicitly specified. However, pacman configuration still requires this option in order to be able to deal with boolean values	2022-10-18 02:13:01 +03:00
Evgenii Alekseev	342b3cb652	Add gitremote triggers (#68 ) * add gitremote pull trigger * add push gitremote trigger * docs update	2022-10-18 01:46:27 +03:00
Evgeniy Alekseev	fc0d8387df	extend triggers to on_start and on_stop methods This commit also replaces old run method to new on_result	2022-09-26 01:22:54 +03:00
Evgeniy Alekseev	e0b0c3caeb	add minimal install step to workflow	2022-09-17 14:52:08 +03:00
Evgeniy Alekseev	61969dd682	make sqlite import consistent	2022-09-17 14:32:21 +03:00
