From 0ca459ea334ff86016bda241c0c823178789c215 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff Date: Wed, 25 Jul 2018 22:10:39 +0100 Subject: Basic support for room versioning This is the first tranche of support for room versioning. It includes: * setting the default room version in the config file * new room_version param on the createRoom API * storing the version of newly-created rooms in the m.room.create event * fishing the version of existing rooms out of the m.room.create event --- synapse/api/constants.py | 6 ++++++ synapse/api/errors.py | 2 ++ synapse/config/server.py | 14 ++++++++++++ synapse/handlers/room.py | 27 ++++++++++++++++++++++- synapse/replication/slave/storage/events.py | 2 +- synapse/storage/state.py | 33 ++++++++++++++++++++++++++--- 6 files changed, 79 insertions(+), 5 deletions(-) (limited to 'synapse') diff --git a/synapse/api/constants.py b/synapse/api/constants.py index 4df930c8d1..a27bf3b32d 100644 --- a/synapse/api/constants.py +++ b/synapse/api/constants.py @@ -1,6 +1,7 @@ # -*- coding: utf-8 -*- # Copyright 2014-2016 OpenMarket Ltd # Copyright 2017 Vector Creations Ltd +# Copyright 2018 New Vector Ltd. # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. @@ -94,3 +95,8 @@ class RoomCreationPreset(object): class ThirdPartyEntityKind(object): USER = "user" LOCATION = "location" + + +# vdh-test-version is a placeholder to get room versioning support working and tested +# until we have a working v2. +KNOWN_ROOM_VERSIONS = {"1", "vdh-test-version"} diff --git a/synapse/api/errors.py b/synapse/api/errors.py index b41d595059..477ca07a24 100644 --- a/synapse/api/errors.py +++ b/synapse/api/errors.py @@ -1,5 +1,6 @@ # -*- coding: utf-8 -*- # Copyright 2014-2016 OpenMarket Ltd +# Copyright 2018 New Vector Ltd. # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. @@ -56,6 +57,7 @@ class Codes(object): CONSENT_NOT_GIVEN = "M_CONSENT_NOT_GIVEN" CANNOT_LEAVE_SERVER_NOTICE_ROOM = "M_CANNOT_LEAVE_SERVER_NOTICE_ROOM" MAU_LIMIT_EXCEEDED = "M_MAU_LIMIT_EXCEEDED" + UNSUPPORTED_ROOM_VERSION = "M_UNSUPPORTED_ROOM_VERSION" class CodeMessageException(RuntimeError): diff --git a/synapse/config/server.py b/synapse/config/server.py index 6a471a0a5e..68ef2789d3 100644 --- a/synapse/config/server.py +++ b/synapse/config/server.py @@ -16,6 +16,7 @@ import logging +from synapse.api.constants import KNOWN_ROOM_VERSIONS from synapse.http.endpoint import parse_and_validate_server_name from ._base import Config, ConfigError @@ -75,6 +76,16 @@ class ServerConfig(Config): ) else: self.max_mau_value = 0 + + # the version of rooms created by default on this server + self.default_room_version = str(config.get( + "default_room_version", "1", + )) + if self.default_room_version not in KNOWN_ROOM_VERSIONS: + raise ConfigError("Unrecognised value '%s' for default_room_version" % ( + self.default_room_version, + )) + # FIXME: federation_domain_whitelist needs sytests self.federation_domain_whitelist = None federation_domain_whitelist = config.get( @@ -249,6 +260,9 @@ class ServerConfig(Config): # (except those sent by local server admins).
