From f55836929d3c64f3f8d883d8f3643a88b6c9cbca Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Tue, 29 Jun 2021 12:00:04 -0400 Subject: [PATCH] Do not recurse into non-spaces in the spaces summary. (#10256) Previously m.child.room events in non-space rooms would be treated as part of the room graph, but this is no longer supported. --- changelog.d/10256.misc | 1 + synapse/api/constants.py | 6 ++++ synapse/handlers/space_summary.py | 11 +++++-- tests/handlers/test_space_summary.py | 48 +++++++++++++++------------- tests/rest/client/v1/utils.py | 3 +- 5 files changed, 43 insertions(+), 26 deletions(-) create mode 100644 changelog.d/10256.misc diff --git a/changelog.d/10256.misc b/changelog.d/10256.misc new file mode 100644 index 0000000000..adef12fcb9 --- /dev/null +++ b/changelog.d/10256.misc @@ -0,0 +1 @@ +Improve the performance of the spaces summary endpoint by only recursing into spaces (and not rooms in general). diff --git a/synapse/api/constants.py b/synapse/api/constants.py index 414e4c019a..8363c2bb0f 100644 --- a/synapse/api/constants.py +++ b/synapse/api/constants.py @@ -201,6 +201,12 @@ class EventContentFields: ) +class RoomTypes: + """Understood values of the room_type field of m.room.create events.""" + + SPACE = "m.space" + + class RoomEncryptionAlgorithms: MEGOLM_V1_AES_SHA2 = "m.megolm.v1.aes-sha2" DEFAULT = MEGOLM_V1_AES_SHA2 diff --git a/synapse/handlers/space_summary.py b/synapse/handlers/space_summary.py index 17fc47ce16..266f369883 100644 --- a/synapse/handlers/space_summary.py +++ b/synapse/handlers/space_summary.py @@ -25,6 +25,7 @@ from synapse.api.constants import ( EventTypes, HistoryVisibility, Membership, + RoomTypes, ) from synapse.events import EventBase from synapse.events.utils import format_event_for_client_v2 @@ -318,7 +319,8 @@ class SpaceSummaryHandler: Returns: A tuple of: - An iterable of a single value of the room. + The room information, if the room should be returned to the + user.
