+# Flaschengeist
+![status-badge](https://ci.os-sc.org/api/badges/Flaschengeist/flaschengeist/status.svg)
+
+This is the backend of the Flaschengeist.
+
+## Installation
+### Requirements
+- `mysql` or `mariadb`
+    - maybe `libmariadb` development files[1]
+- python 3.9+
+- pip 21.0+
+
+*[1] By default Flaschengeist uses mysql as database backend, if you are on Windows Flaschengeist uses `PyMySQL`, but on
+Linux / Mac the faster `mysqlclient` is used, if it is not already installed installing from pypi requires the
+development files for `libmariadb` to be present on your system.*
+
+### Install python files
+It is recommended to upgrade pip to the latest version before installing:
+
+    python -m pip install --upgrade pip
+
+Default installation with *mariadb*/*mysql* support:
+
+    pip3 install --user ".[mysql]"
+
+or with ldap support
+
+    pip3 install --user ".[ldap]"
+
+or if you want to also run the tests:
+
+    pip3 install --user ".[ldap,tests]"
+
+You will also need a MySQL driver, by default one of this is installed:
+- `mysqlclient` (non Windows)
+- `PyMySQL` (on Windows)
+
+#### Hint on MySQL driver on Windows:
+If you want to use `mysqlclient` instead of `PyMySQL` (performance?) you have to follow [this guide](https://www.radishlogic.com/coding/python-3/installing-mysqldb-for-python-3-in-windows/)
+
+### Install database
+The user needs to have full permissions to the database.
+If not you need to create user and database manually do (or similar on Windows):
+
+    (
+        echo "CREATE DATABASE flaschengeist;"
+        echo "CREATE USER 'flaschengeist'@'localhost' IDENTIFIED BY 'flaschengeist';"
+        echo "GRANT ALL PRIVILEGES ON flaschengeist.* TO 'flaschengeist'@'localhost';"
+        echo "FLUSH PRIVILEGES;"
+    ) | sudo mysql
+
+Then you can install the database tables, this will update all tables from core + all enabled plugins.
+And also install all enabled plugins:
+
+    $ flaschengeist install
+
+*Hint:* To only install the database tables, or upgrade the database after plugins or core are updated later
+you can use this command:
+
+    $ flaschengeist db upgrade heads
+
+
+## Plugins
+To only upgrade one plugin (for example the `events` plugin):
+
+    $ flaschengeist db upgrade events@head
+
+## Configuration
+Configuration is done within the a `flaschengeist.toml`file, you can copy the one located inside the module path
+(where flaschegeist is installed) or create an empty one and place it inside either:
+1. `~/.config/`
+2. A custom path and set environment variable `FLASCHENGEIST_CONF`
+
+Uncomment and change at least all the database parameters!
+
+#### CRON
+Some functionality used by some plugins rely on regular updates,
+but as flaschengeists works as an WSGI app it can not controll when it gets called.
+
+So you have to configure one of the following options to call flaschengeists CRON tasks:
+
+1. Passive Web-CRON: Every time an users calls flaschengeist a task is scheduled (**NOT RECOMMENDED**)
+  - Pros: No external configuration needed
+  - Cons: Slower user experience, no guaranteed execution time of tasks
+2. Active Web-CRON: You configure a webworker to call `<flaschengeist>/cron`
+  - Pros: Guaranteed execution interval, no impact on user experience (at least if you do not limit wsgi worker threads)
+  - Cons: Uses one of the webserver threads while executing
+
+### Run
+Flaschengeist provides a CLI, based on the flask CLI, respectivly called `flaschengeist`.
+
+⚠️ When using the CLI for running Flaschengeist, please note that logging will happen as configured,
+with the difference of the main logger will be forced to output to `stderr` and the logging level
+of the CLI will override the logging level you have configured for the main logger.
+
+    $ flaschengeist run
+
+or with debug messages:
+
+    $ flaschengeist run --debug
+
+This will run the backend on http://localhost:5000
+
+## Tests
+    $ pip install '.[test]'
+    $ pytest
+Run with coverage report:
+
+    $ coverage run -m pytest
+    $ coverage report
+Or with html output (open `htmlcov/index.html` in a browser):
+
+    $ coverage html

+# Plugin Development
+
+## File Structure
+
+    - your_plugin/
+        - __init__.py
+        - ...
+        - migrations/ (optional)
+            - ...
+    - setup.cfg
+
+The basic layout of a plugin is quite simple, you will only need the `setup.cfg` or `setup.py` and
+the package containing your plugin code, at lease a `__init__.py` file with your `Plugin` class.
+
+If you use custom database tables you need to provide a `migrations` directory within your package,
+see next section.
+
+## Database Tables / Migrations
+To allow upgrades of installed plugins, the database is versioned and handled
+through [Alembic](https://alembic.sqlalchemy.org/en/latest/index.html) migrations.
+Each plugin, which uses custom database tables, is represented as an other base.
+So you could simply follow the Alembic tutorial on [how to work with multiple bases](https://alembic.sqlalchemy.org/en/latest/branches.html#creating-a-labeled-base-revision).
+
+A quick overview on how to work with migrations for your plugin:
+
+    $ flaschengeist db revision -m "Create my super plugin" \
+      --head=base --branch-label=myplugin_name --version-path=your/plugin/migrations
+
+This would add a new base named `myplugin_name`, which should be the same as the pypi name of you plugin.
+If your tables depend on an other plugin or a specific base version you could of cause add
+
+    --depends-on=VERSION
+
+or
+
+    --depends-on=other_plugin
+
+
+### Plugin Removal and Database Tables
+As generic downgrades are most often hard to write, your plugin is not required to provide such functionallity.
+For Flaschengeist only instable versions provide meaningful downgrade migrations down to the latest stable version.
+
+So this means if you do not provide downgrades you must at lease provide a series of migrations toward removal of
+the database tables in case the users wants to delete the plugin.
+
+    (base) ----> 1.0 <----> 1.1 <----> 1.2
+                  |         
+                  --> removal
+
+After the removal step the database is stamped to to "remove" your
+
+## Useful Hooks
+There are some predefined hooks, which might get handy for you.

-# Flaschengeist
-This is the backend of the Flaschengeist.
-
-## Installation
-### Requirements
-- `mysql` or `mariadb`
-    - maybe `libmariadb` development files[1]
-- python 3.7+
-
-[1] By default Flaschengeist uses mysql as database backend, if you are on Windows Flaschengeist uses `PyMySQL`, but on
-Linux / Mac the faster `mysqlclient` is used, if it is not already installed installing from pypi requires the
-development files for `libmariadb` to be present on your system.
-
-### Install python files
-    pip3 install --user .
-or with ldap support
-
-    pip3 install --user ".[ldap]"
-or if you want to also run the tests:
-
-    pip3 install --user ".[ldap,test]"
-
-You will also need a MySQL driver, recommended drivers are
-- `mysqlclient`
-- `PyMySQL`
-
-`setup.py` will try to install a matching driver.
-
-#### Windows
-Same as above, but if you want to use `mysqlclient` instead of `PyMySQL` (performance?) you have to follow this guide:
-
-https://www.radishlogic.com/coding/python-3/installing-mysqldb-for-python-3-in-windows/
-
-### Configuration
-Configuration is done within the a `flaschengeist.toml`file, you can copy the one located inside the module path
-(where flaschegeist is installed) or create an empty one and place it inside either:
-1. `~/.config/`
-2. A custom path and set environment variable `FLASCHENGEIST_CONF`
-
-Uncomment and change at least all the database parameters!
-
-### Database installation
-The user needs to have full permissions to the database.
-If not you need to create user and database manually do (or similar on Windows):
-
-    (
-        echo "CREATE DATABASE flaschengeist;"
-        echo "CREATE USER 'flaschengeist'@'localhost' IDENTIFIED BY 'flaschengeist';"
-        echo "GRANT ALL PRIVILEGES ON flaschengeist.* TO 'flaschengeist'@'localhost';"
-        echo "FLUSH PRIVILEGES;"
-    ) | sudo mysql
-
-Then you can install the database tables and initial entries:
-
-    run_flaschengeist install
-
-### Run
-    run_flaschengeist run
-or with debug messages:
-
-    run_flaschengeist run --debug
-
-This will run the backend on http://localhost:5000
-
-## Tests
-    $ pip install '.[test]'
-    $ pytest
-Run with coverage report:
-
-    $ coverage run -m pytest
-    $ coverage report
-Or with html output (open `htmlcov/index.html` in a browser):
-
-    $ coverage html
-
-## Development
-Please refer to our [development wiki](https://flaschengeist.dev/Flaschengeist/flaschengeist/wiki/Development).
