Synapse Domain Rule Checker
A module to prevent invites and joins to Matrix rooms by checking the involved server(s)' domain.
Installation
From the virtual environment that you use for Synapse, install this module with:
pip install synapse-domain-rule-checker
(If you run into issues, you may need to upgrade pip first, e.g. by running pip install --upgrade pip)
Then alter your homeserver configuration, adding to your modules configuration:
modules:
- module: synapse_domain_rule_checker.DomainRuleChecker
config:
# A mapping describing which servers a server can invite into a room.
# Default is any server can invite any other server.
domain_mapping:
"inviter_domain": [ "invitee_domain_permitted", "other_domain_permitted" ]
"other_inviter_domain": [ "invitee_domain_permitted" ]
# Whether an invite should be allowed through if the inviting server doesn't appear
# in the domain_mapping.
# Required.
can_invite_if_not_in_domain_mapping: false
# Whether a user on this server needs to be invited to be allowed into a room,
# regardless of the room's settings.
# Defaults to false.
can_only_join_rooms_with_invite: false
# Whether a user on this server can only invite when creating a room.
# Default is false.
can_only_invite_during_room_creation: false
# List of servers that can't be invited to rooms that have been published to the
# public room directory. This setting only really works in a closed federation in
# which every server agrees on the list.
# Defaults to all servers being allowed.
domains_prevented_from_being_invited_to_published_rooms: []
# Whether a local user can invite another user using a third-party identifier (e.g.
# an email address).
# Defaults to true.
can_invite_by_third_party_id: true
Note that you need to consider invites between two local users when defining values for domain_mapping and domains_prevented_from_being_invited_to_published_rooms.
Development
In a virtual environment with pip ≥ 21.1, run
pip install -e .[dev]
To run the unit tests, you can either use:
tox -e py
or
trial tests
To run the linters and mypy type checker, use ./scripts-dev/lint.sh.
Releasing
The exact steps for releasing will vary; but this is an approach taken by the Synapse developers (assuming a Unix-like shell):
-
Set a shell variable to the version you are releasing (this just makes subsequent steps easier):
version=X.Y.Z
-
Update
setup.cfgso that theversionis correct. -
Stage the changed files and commit.
git add -u git commit -m v$version -n -
Push your changes.
git push
-
When ready, create a signed tag for the release:
git tag -s v$versionBase the tag message on the changelog.
-
Push the tag.
git push origin tag v$version -
Create a source distribution and upload it to PyPI:
python -m build twine upload dist/synapse_domain_rule_checker-$version*
