Release 2.6.0

This commit also extends configuration of the multilib option, adding
the ability to exlcude multilib repository from repositories list

Note, that in order to support repository list and mirror correctly,
alpm configuration section is now architectture specific

 Again, the most checks can be performed by `make check` command, though some additional guidelines must be applied:
 
 * Every class, every function (including private and protected), every attribute must be documented. The project follows [Google style documentation](https://google.github.io/styleguide/pyguide.html). The only exception is local functions.
+* Correct way to document function, if section is empty, e.g. no notes or there are no args, it should be omitted:
+
+    ```python
+    def foo(argument: str, *, flag: bool = False) -> int:
+        """
+        do foo. With very very very long
+        docstring
+  
+        Note:
+            Very important note about this function
+  
+        Args:
+            argument(str): an argument. This argument has
+                long description also
+            flag(bool, optional): a flag (Default value = False)
+  
+        Returns:
+            int: result
+  
+        Raises:
+            RuntimeException: a local function error occurs
+  
+        Examples:
+            Very informative example how to use this function, e.g.::
+  
+                >>> foo("argument", flag=False)
+  
+            Note that function documentation is in rST.
+        """
+    ```
+  
+  `Returns` should be replaced with `Yields` for generators.
+
+  Class attributes should be documented in the following way:
+
+    ```python
+    class Clazz(BaseClazz):
+        """
+        brand-new implementation of ``BaseClazz``
+  
+        Attributes:
+            CLAZZ_ATTRIBUTE(int): (class attribute) a brand-new class attribute
+            instance_attribute(str): an instance attribute
+  
+        Examples:
+            Very informative class usage example, e.g.::
+  
+                >>> from module import Clazz
+                >>> clazz = Clazz()
+        """
+  
+        CLAZZ_ATTRIBUTE = 42

+            """
+            self.instance_attribute = ""
+    ```
+
 * Type annotations are the must, even for local functions.
+* Recommended order of function definitions in class:
+
+    ```python
+    class Clazz:
+  
+        def __init__(self) -> None: ...  # replace with `__post_init__` for dataclasses
+
+        @property

+        def usual_method(self) -> Any: ...
+
+        def __hash__(self) -> int: ...  # basically any magic (or look-alike) method
+    ```
+  
+  Methods inside one group should be ordered alphabetically, the only exception is `__init__` method (`__post__init__` for dataclasses) which should be defined first. For test methods it is recommended to follow the order in which functions are defined.
+
+  Though, we would like to highlight abstract methods (i.e. ones which raise `NotImplementedError`), we still keep in global order at the moment.
+
+* Abstract methods must raise `NotImplementedError` instead of using `abc.abstractmethod`. The reason behind this restriction is the fact that we have class/static abstract methods for those we need to define their attribute first making the code harder to read.
 * For any path interactions `pathlib.Path` must be used.
 * Configuration interactions must go through `ahriman.core.configuration.Configuration` class instance.
 * In case if class load requires some actions, it is recommended to create class method which can be used for class instantiating.

 * One file should define only one class, exception is class satellites in case if file length remains less than 400 lines.
 * It is possible to create file which contains some functions (e.g. `ahriman.core.util`), but in this case you would need to define `__all__` attribute.
 * The file size mentioned above must be applicable in general. In case of big classes consider splitting them into traits. Note, however, that `pylint` includes comments and docstrings into counter, thus you need to check file size by other tools.

+* No global variable is allowed outside of `ahriman.version` module. `ahriman.core.context` is also special case.
 * Single quotes are not allowed. The reason behind this restriction is the fact that docstrings must be written by using double quotes only, and we would like to make style consistent.
 * If your class writes anything to log, the `ahriman.core.log.LazyLogging` trait must be used.

 Application is designed to run from ``systemd`` services and provides parametrized by architecture timer and service file for that.
 
+Subcommand design
+^^^^^^^^^^^^^^^^^
+
+All subcommands are divided into several groups depending on the role they are doing:
+
+* ``aur`` (``aur-search``) group is for AUR operations.
+* ``help`` (e.g. ``help``) are system commands.
+* ``package`` subcommands (e.g. ``package-add``) allow to perform single package actions.
+* ``patch`` subcommands (e.g. ``pacth-list``) are the special case of ``package`` subcommands introduced in order to control patches for packages.
+* ``repo`` subcommands (e.g. ``repo-check``) usually perform actions on whole repository.
+* ``service`` subcommands (e.g. ``service-setup``) perform actions which are related to whole service managing: create repository, show configuration.
+* ``user`` subcommands (``user-add``) are intended for user management.
+* ``web`` subcommands are related to web service management.
+
+For historical reasons and in order to keep backward compatibility some subcommands have aliases to their shorter forms or even other groups, but the service doesn't guarantee that they will remain unchanged.

 For every external command run (which is actually not recommended if possible) custom wrapper for ``subprocess`` is used. Additional functions ``ahriman.core.auth.helpers`` provide safe calls for ``aiohttp_security`` methods and are required to make this dependency optional.
 
+Context variables
+^^^^^^^^^^^^^^^^^
+
+Package provides implicit global variables which can be accessed from ``ahriman.core`` package as ``context`` variable, wrapped by ``contextvars.ContextVar`` class. The value of the variable is defaulting to private ``_Context`` class which is defined in the same module. The default values - such as ``database`` and ``sign`` - are being set on the service initialization.
+
+The ``_Context`` class itself mimics default collection interface (as is Mapping) and can be modified by ``_Context.set`` method. The stored variables can be achieved by ``_Context.get`` method, which is unlike default ``Mapping`` interface also performs type and presence checks.
+
+In order to provide statically typed interface, the ``ahriman.models.context_key.ContextKey`` class is used for both ``_Content.get`` and ``_Content.set`` methods; the context instance itself, however, does not store information about types.

+Non-x86_64 architecture setup
+-----------------------------
+
+The following section describes how to setup ahriman with architecture different from x86_64, as example i686. For most cases you have base repository available, e.g. archlinux32 repositories for i686 architecture; in case if base repository is not available, steps are a bit different, however, idea remains the same.
+
+Physical server setup
+^^^^^^^^^^^^^^^^^^^^^
+
+In this example we are going to use files and packages which are provided by official repositories of the used architecture. Note, that versions might be different, thus you need to find correct versions on the distribution web site, e.g. `archlinux32 packages <https://www.archlinux32.org/packages/>`_.
+
+#.
+   First, considering having base Arch Linux system, we need to install keyring for the specified repositories:
+
+   .. code-block:: shell
+
+      wget http://pool.mirror.archlinux32.org/i686/core/archlinux32-keyring-20220927-1.0-any.pkg.tar.zst
+      pacman -U archlinux32-keyring-20220927-1.0-any.pkg.tar.zst
+
+#.
+   In order to run ``devtools`` scripts for custom architecture they also need specific ``makepkg`` configuration, it can be retrieved by installing the ``devtools`` package of the distribution:
+
+   .. code-block:: shell
+
+      wget http://pool.mirror.archlinux32.org/i686/extra/devtools-20221208-1.0-any.pkg.tar.zst
+      pacman -U devtools-20221208-1.0-any.pkg.tar.zst
+
+   Alternatively, you can create your own ``makepkg`` configuration and save it as ``/usr/share/devtools/makepkg-i686.conf``.
+
+#.
+   Setup repository as usual:
+
+   .. code-block:: shell
+
+      ahriman -a i686 service-setup --mirror 'http://de.mirror.archlinux32.org/$arch/$repo'--no-multilib ...
+
+   In addition to usual options, you need to specify the following options:
+
+   * ``--mirror`` - link to the mirrors which will be used instead of official repositories.
+   * ``--no-multilib`` - in the example we are using i686 architecture for which multilib repository doesn't exist.
+
+Docker container setup
+^^^^^^^^^^^^^^^^^^^^^^
+
+There are two possible ways to achieve same setup, by using docker container. The first one is just mount required files inside container and run it as usual (with specific environment variables). Another one is to create own container based on official one:
+
+#.
+   Clone official container as base:
+
+   .. code-block:: dockerfile
+
+      FROM arcan1s/ahriman:latest
+
+#.
+   Init pacman keys. This command is required in order to populate distribution keys:
+
+   .. code-block:: dockerfile
+
+      RUN pacman-key --init
+
+#.
+   Install packages as it was described above:
+
+   .. code-block:: dockerfile
+
+      RUN pacman --noconfirm -Sy wget
+      RUN wget http://pool.mirror.archlinux32.org/i686/extra/devtools-20221208-1.0-any.pkg.tar.zst && pacman --noconfirm -U devtools-20221208-1.0-any.pkg.tar.zst
+      RUN wget http://pool.mirror.archlinux32.org/i686/core/archlinux32-keyring-20220927-1.0-any.pkg.tar.zst && pacman --noconfirm -U archlinux32-keyring-20220927-1.0-any.pkg.tar.zst
+
+#.
+   At that point you should have full ``Dockerfile`` like:
+
+   .. code-block:: dockerfile
+
+      FROM arcan1s/ahriman:latest
+
+      RUN pacman-key --init
+
+      RUN pacman --noconfirm -Sy wget
+      RUN wget http://pool.mirror.archlinux32.org/i686/extra/devtools-20221208-1.0-any.pkg.tar.zst && pacman --noconfirm -U devtools-20221208-1.0-any.pkg.tar.zst
+      RUN wget http://pool.mirror.archlinux32.org/i686/core/archlinux32-keyring-20220927-1.0-any.pkg.tar.zst && pacman --noconfirm -U archlinux32-keyring-20220927-1.0-any.pkg.tar.zst
+
+#.
+   After that you can build you own container, e.g.:
+
+   .. code-block:: shell
+
+      docker build --tag ahriman-i686:latest
+
+#.
+   Now you can run locally built container as usual with passing environment variables for setup command:
+
+   .. code-block:: shell
+
+      docker run --privileged -p 8080:8080 -e AHRIMAN_ARCHITECTURE=i686 -e AHRIMAN_PACMAN_MIRROR='http://de.mirror.archlinux32.org/$arch/$repo' -e AHRIMAN_MULTILIB= ahriman-i686:latest

 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).
 
+Context variables
+-----------------
+
+By default, only configuration and architecture are passed to triggers. However, some triggers might want to have access to other high-level wrappers. In order to provide such ability and avoid (double) initialization, the service provides a global context variables, which can be accessed from ``ahriman.core`` package:
+
+.. code-block:: python
+
+   from ahriman.core import context
+
+   ctx = context.get()
+
+Just because context is wrapped inside ``contexvars.ContextVar``, you need to explicitly extract variable by ``get()`` method. Later you can extract any variable if it is set, e.g.:
+
+.. code-block:: python
+
+   from ahriman.core.database import SQLite
+   from ahriman.models.context_key import ContextKey
+
+   database = ctx.get(ContextKey("database", SQLite))
+
+In order to provide typed API, all variables are stored together with their type. The ``get(ContextKey)`` method will throw ``KeyError`` in case if key is missing. Alternatively you can set your own variable inside context:
+
+.. code-block:: python
+
+   ctx.set(ContextKey("answer", int), 42)
+   context.set(ctx)
+
+Note, however, that there are several limitations:
+
+* Context variables are immutable, thus you cannot override value if the key already presented.
+* The ``return_type`` of ``ContextKey`` should match the value type, otherwise exception will be thrown.
+
+The ``context`` also implements collection methods such as ``__iter__`` and ``__len__``.

@@ -91,3 +125,8 @@ Setup the trigger
 First, put the trigger in any path it can be exported, e.g. by packing the resource into python package (which will lead to import path as ``package.slack_reporter.SlackReporter``) or just put file somewhere it can be accessed by application (e.g. ``/usr/local/lib/slack_reporter.py.SlackReporter``).
 
 After that run application as usual and receive notification in your slack channel.

+Trigger configuration schema

+Triggers can expose their configuration schema. It can be achieved by implementing ``CONFIGURATION_SCHEMA`` class variable according to `cerberus <https://docs.python-cerberus.org/>`_ documentation. For more details and examples, please refer to built-in triggers implementations.
