From 2a51f3ec36abeb1f5c1db795541988d1d9698e41 Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Fri, 27 Jan 2023 10:16:21 -0500 Subject: [PATCH] Implement MSC3952: Intentional mentions (#14823) MSC3952 defines push rules which searches for mentions in a list of Matrix IDs in the event body, instead of searching the entire event body for display name / local part. This is implemented behind an experimental configuration flag and does not yet implement the backwards compatibility pieces of the MSC. --- changelog.d/14823.feature | 1 + rust/src/push/base_rules.rs | 21 +++++ rust/src/push/evaluator.rs | 25 +++++- rust/src/push/mod.rs | 34 ++++++++ stubs/synapse/synapse_rust/push.pyi | 5 +- synapse/api/constants.py | 3 + synapse/config/experimental.py | 5 ++ synapse/push/bulk_push_rule_evaluator.py | 25 +++++- synapse/storage/databases/main/push_rule.py | 1 + tests/push/test_bulk_push_rule_evaluator.py | 88 +++++++++++++++++++++ tests/push/test_push_rule_evaluator.py | 66 ++++++++++++++-- 11 files changed, 263 insertions(+), 11 deletions(-) create mode 100644 changelog.d/14823.feature diff --git a/changelog.d/14823.feature b/changelog.d/14823.feature new file mode 100644 index 0000000000..8293e99eff --- /dev/null +++ b/changelog.d/14823.feature @@ -0,0 +1 @@ +Experimental support for [MSC3952](https://github.com/matrix-org/matrix-spec-proposals/pull/3952): intentional mentions. diff --git a/rust/src/push/base_rules.rs b/rust/src/push/base_rules.rs index 9140a69bb6..880eed0ef4 100644 --- a/rust/src/push/base_rules.rs +++ b/rust/src/push/base_rules.rs @@ -131,6 +131,14 @@ pub const BASE_APPEND_OVERRIDE_RULES: &[PushRule] = &[ default: true, default_enabled: true, }, + PushRule { + rule_id: Cow::Borrowed(".org.matrix.msc3952.is_user_mentioned"), + priority_class: 5, + conditions: Cow::Borrowed(&[Condition::Known(KnownCondition::IsUserMention)]), + actions: Cow::Borrowed(&[Action::Notify, HIGHLIGHT_ACTION, SOUND_ACTION]), + default: true, + default_enabled: true, + }, PushRule { rule_id: Cow::Borrowed("global/override/.m.rule.contains_display_name"), priority_class: 5, @@ -139,6 +147,19 @@ pub const BASE_APPEND_OVERRIDE_RULES: &[PushRule] = &[ default: true, default_enabled: true, }, + PushRule { + rule_id: Cow::Borrowed(".org.matrix.msc3952.is_room_mentioned"), + priority_class: 5, + conditions: Cow::Borrowed(&[ + Condition::Known(KnownCondition::IsRoomMention), + Condition::Known(KnownCondition::SenderNotificationPermission { + key: Cow::Borrowed("room"), + }), + ]), + actions: Cow::Borrowed(&[Action::Notify, HIGHLIGHT_ACTION, SOUND_ACTION]), + default: true, + default_enabled: true, + }, PushRule { rule_id: Cow::Borrowed("global/override/.m.rule.roomnotif"), priority_class: 5, diff --git a/rust/src/push/evaluator.rs b/rust/src/push/evaluator.rs index 0242ee1c5f..aa71202e43 100644 --- a/rust/src/push/evaluator.rs +++ b/rust/src/push/evaluator.rs @@ -12,7 +12,7 @@ // See the License for the specific language governing permissions and // limitations under the License. -use std::collections::BTreeMap; +use std::collections::{BTreeMap, BTreeSet}; use anyhow::{Context, Error}; use lazy_static::lazy_static; @@ -68,6 +68,11 @@ pub struct PushRuleEvaluator { /// The "content.body", if any. body: String, + /// The user mentions that were part of the message. + user_mentions: BTreeSet, + /// True if the message is a room message. + room_mention: bool, + /// The number of users in the room. room_member_count: u64, @@ -100,6 +105,8 @@ impl PushRuleEvaluator { #[new] pub fn py_new( flattened_keys: BTreeMap, + user_mentions: BTreeSet, + room_mention: bool, room_member_count: u64, sender_power_level: Option, notification_power_levels: BTreeMap, @@ -116,6 +123,8 @@ impl PushRuleEvaluator { Ok(PushRuleEvaluator { flattened_keys, body, + user_mentions, + room_mention, room_member_count, notification_power_levels, sender_power_level, @@ -229,6 +238,14 @@ impl PushRuleEvaluator { KnownCondition::RelatedEventMatch(event_match) => { self.match_related_event_match(event_match, user_id)?
