+
+This module provides a way to define an environment in the main Odoo
+configuration file and to read some configurations from files depending
+on the configured environment: you define the environment in the main
+configuration file, and the values for the various possible environments
+are stored in the ``server_environment_files`` companion module.
+
+The ``server_environment_files`` module is optional, the values can be
+set using an environment variable with a fallback on default values in
+the database.
+
+The configuration read from the files are visible under the
+Configuration menu. If you are not in the 'dev' environment you will not
+be able to see the values contained in the defined secret keys (by
+default : '*passw*', '*key*', '*secret*' and '*token*').
+

+
+Installation
+============
+
+By itself, this module does little. See for instance the
+``mail_environment`` addon which depends on this one to allow
+configuring the incoming and outgoing mail servers depending on the
+environment.
+
+You can store your configuration values in a companion module called
+``server_environment_files``. You can copy and customize the provided
+``server_environment_files_sample`` module for this purpose.
+Alternatively, you can provide them in environment variables
+``SERVER_ENV_CONFIG`` and ``SERVER_ENV_CONFIG_SECRET``.
+
+Configuration
+=============
+
+To configure this module, you need to edit the main configuration file
+of your instance, and add a directive called ``running_env``. Commonly
+used values are 'dev', 'test', 'production':
+
+::
+
+   [options]
+   running_env=dev
+
+Or set the ``RUNNING_ENV`` or ``ODOO_STAGE`` environment variable. If
+both all are set config file will take the precedence on environment and
+``RUNNING_ENV`` over ``ODOO_STAGE``.
+
+``ODOO_STAGE`` is used for odoo.sh platform where we can't set
+``RUNNING_ENV``, possible observed values are ``production``,
+``staging`` and ``dev``
+
+Values associated to keys containing 'passw' are only displayed in the
+'dev' environment.
+
+If you don't provide any value, test is used as a safe default.
+
+You have several possibilities to set configuration values:
+
+server_environment_files
+------------------------
+
+You can edit the settings you need in the ``server_environment_files``
+addon. The ``server_environment_files_sample`` can be used as an
+example:
+
+-  values common to all / most environments can be stored in the
+   ``default/`` directory using the .ini file syntax;
+-  each environment you need to define is stored in its own directory
+   and can override or extend default values;
+-  you can override or extend values in the main configuration file of
+   your instance;
+
+Environment variable
+--------------------
+
+You can define configuration in the environment variable
+``SERVER_ENV_CONFIG`` and/or ``SERVER_ENV_CONFIG_SECRET``. The 2
+variables are handled the exact same way, this is only a convenience for
+the deployment where you can isolate the secrets in a different,
+encrypted, file. They are multi-line environment variables in the same
+configparser format than the files. If you used options in
+``server_environment_files``, the options set in the environment
+variable override them.
+
+The options in the environment variable are not dependent of
+``running_env``, the content of the variable must be set accordingly to
+the running environment.
+
+Example of setup:
+
+A public file, containing that will contain public variables:
+
+::
+
+   # These variables are not odoo standard variables,
+   # they are there to represent what your file could look like
+   export WORKERS='8'
+   export MAX_CRON_THREADS='1'
+   export LOG_LEVEL=info
+   export LOG_HANDLER=":INFO"
+   export DB_MAXCONN=5
+
+   # server environment options
+   export SERVER_ENV_CONFIG="
+   [storage_backend.my_sftp]
+   sftp_server=10.10.10.10
+   sftp_login=foo
+   sftp_port=22200
+   directory_path=Odoo
+   "
+
+A second file which is encrypted and contains secrets:
+
+::
+
+   # This variable is not an odoo standard variable,
+   # it is there to represent what your file could look like
+   export DB_PASSWORD='xxxxxxxxx'
+   # server environment options
+   export SERVER_ENV_CONFIG_SECRET="
+   [storage_backend.my_sftp]
+   sftp_password=xxxxxxxxx
+   "
+
+**WARNING**
+
+   my_sftp must match the name of the record. If you want something more
+   reliable use server.env.techname.mixin and use tech_name field to
+   reference records. See "USAGE".
+
+Default values
+--------------
+
+When using the ``server.env.mixin`` mixin, for each env-computed field,
+a companion field ``<field>_env_default`` is created. This field is not
+environment-dependent. It's a fallback value used when no key is set in
+configuration files / environment variable.
+
+When the default field is used, the field is made editable on Odoo.
+
+Note: empty environment keys always take precedence over default fields
+
+Server environment integration
+------------------------------
+
+Read the documentation of the class
+`models/server_env_mixin.py <models/server_env_mixin.py>`__.
+
+Usage
+=====
+
+You can include a mixin in your model and configure the env-computed
+fields by an override of ``_server_env_fields``.
+
+::
+
+   class StorageBackend(models.Model):
+       _name = "storage.backend"
+       _inherit = ["storage.backend", "server.env.mixin"]
+
+       @property
+       def _server_env_fields(self):
+           return {"directory_path": {}}
+
+Read the documentation of the class and methods in
+`models/server_env_mixin.py <models/server_env_mixin.py>`__.
+
+If you want to have a technical name to reference:
+
+::
+
+   class StorageBackend(models.Model):
+       _name = "storage.backend"
+       _inherit = ["storage.backend", "server.env.techname.mixin", "server.env.mixin"]
+
+       [...]
+
+Known issues / Roadmap
+======================
+
+-  it is not possible to set the environment from the command line. A
+   configuration file must be used.
+-  the module does not allow to set low level attributes such as
+   database server, etc.
+-  server.env.techname.mixin's tech_name field could leverage the new
+   option for computable / writable fields and get rid of some onchange
+   / read / write code.
+
