As part of the rollout of [MSC3916](https://github.com/matrix-org/matrix-spec-proposals/blob/main/proposals/3916-authentication-for-media.md) this PR adds support for designating authenticated media and ensuring that authenticated media is not served over unauthenticated endpoints.

SCHEMA_VERSION = 86 # remember to update the list below when updating
|
|
"""Represents the expectations made by the codebase about the database schema
|
|
|
|
This should be incremented whenever the codebase changes its requirements on the
|
|
shape of the database schema (even if those requirements are backwards-compatible with
|
|
older versions of Synapse).
|
|
|
|
See https://element-hq.github.io/synapse/develop/development/database_schema.html
|
|
for more information on how this works.
|
|
|
|
Changes in SCHEMA_VERSION = 61:
|
|
- The `user_stats_historical` and `room_stats_historical` tables are not written and
|
|
are not read (previously, they were written but not read).
|
|
- MSC2716: Add `insertion_events` and `insertion_event_edges` tables to keep track
|
|
of insertion events in order to navigate historical chunks of messages.
|
|
- MSC2716: Add `chunk_events` table to track how the chunk is labeled and
|
|
determines which insertion event it points to.
|
|
|
|
Changes in SCHEMA_VERSION = 62:
|
|
- MSC2716: Add `insertion_event_extremities` table that keeps track of which
|
|
insertion events need to be backfilled.
|
|
|
|
Changes in SCHEMA_VERSION = 63:
|
|
- The `public_room_list_stream` table is not written nor read to
|
|
(previously, it was written and read to, but not for any significant purpose).
|
|
https://github.com/matrix-org/synapse/pull/10565
|
|
|
|
Changes in SCHEMA_VERSION = 64:
|
|
- MSC2716: Rename related tables and columns from "chunks" to "batches".
|
|
|
|
Changes in SCHEMA_VERSION = 65:
|
|
- MSC2716: Remove unique event_id constraint from insertion_event_edges
|
|
because an insertion event can have multiple edges.
|
|
- Remove unused tables `user_stats_historical` and `room_stats_historical`.
|
|
|
|
Changes in SCHEMA_VERSION = 66:
|
|
- Queries on state_key columns are now disambiguated (ie, the codebase can handle
|
|
the `events` table having a `state_key` column).
|
|
|
|
Changes in SCHEMA_VERSION = 67:
|
|
- state_events.prev_state is no longer written to.
|
|
|
|
Changes in SCHEMA_VERSION = 68:
|
|
- event_reference_hashes is no longer read.
|
|
- `events` has `state_key` and `rejection_reason` columns, which are populated for
|
|
new events.
|
|
|
|
Changes in SCHEMA_VERSION = 69:
|
|
- We now write to `device_lists_changes_in_room` table.
|
|
- We now use a PostgreSQL sequence to generate future txn_ids for
|
|
`application_services_txns`. `application_services_state.last_txn` is no longer
|
|
updated.
|
|
|
|
Changes in SCHEMA_VERSION = 70:
|
|
- event_reference_hashes is no longer written to.
|
|
|
|
Changes in SCHEMA_VERSION = 71:
|
|
- event_edges.room_id is no longer read from.
|
|
- Tables related to groups are no longer accessed.
|
|
|
|
Changes in SCHEMA_VERSION = 72:
|
|
- event_edges.(room_id, is_state) are no longer written to.
|
|
- Tables related to groups are dropped.
|
|
- Unused column application_services_state.last_txn is dropped
|
|
- Cache invalidation stream id sequence now begins at 2 to match code expectation.
|
|
|
|
Changes in SCHEMA_VERSION = 73:
|
|
- thread_id column is added to event_push_actions, event_push_actions_staging
|
|
event_push_summary, receipts_linearized, and receipts_graph.
|
|
- Add table `event_failed_pull_attempts` to keep track when we fail to pull
|
|
events over federation.
|
|
- Add indexes to various tables (`event_failed_pull_attempts`, `insertion_events`,
|
|
`batch_events`) to make it easy to delete all associated rows when purging a room.
|
|
- `inserted_ts` column is added to `event_push_actions_staging` table.
|
|
|
|
Changes in SCHEMA_VERSION = 74:
|
|
- A query on `event_stream_ordering` column has now been disambiguated (i.e. the
|
|
codebase can handle the `current_state_events`, `local_current_memberships` and
|
|
`room_memberships` tables having an `event_stream_ordering` column).
|
|
|
|
Changes in SCHEMA_VERSION = 75:
|
|
- The `event_stream_ordering` column in membership tables (`current_state_events`,
|
|
`local_current_membership` & `room_memberships`) is now being populated for new
|
|
rows. When the background job to populate historical rows lands this will
|
|
become the compat schema version.
|
|
|
|
Changes in SCHEMA_VERSION = 76:
|
|
- Adds a full_user_id column to tables profiles and user_filters.
|
|
|
|
Changes in SCHEMA_VERSION = 77
|
|
- (Postgres) Add NOT VALID CHECK (full_user_id IS NOT NULL) to tables profiles and user_filters
|

Changes in SCHEMA_VERSION = 78
|
|
- Validate check (full_user_id IS NOT NULL) on tables profiles and user_filters
|
|
|
|
Changes in SCHEMA_VERSION = 79
|
|
- Add tables to handle in DB read-write locks.
|
|
- Add some mitigations for a painful race between foreground and background updates, cf
|
|
https://github.com/matrix-org/synapse/issues/15677.
|
|
|
|
Changes in SCHEMA_VERSION = 80
|
|
- The event_txn_id_device_id is always written to for new events.
|
|
- Add tables for the task scheduler.

Changes in SCHEMA_VERSION = 81
|
|
- The event_txn_id is no longer written to for new events.
|

Changes in SCHEMA_VERSION = 82

- The insertion_events, insertion_event_extremities, insertion_event_edges, and
|
|
batch_events tables are no longer purged in preparation for their removal.

|
|

Changes in SCHEMA_VERSION = 83
|
|
- The event_txn_id is no longer used.

Changes in SCHEMA_VERSION = 84

|
|
so read operations must do graph traversal.

Changes in SCHEMA_VERSION = 85
|
|
- Add a column `suspended` to the `users` table
|
|
|
|
Changes in SCHEMA_VERSION = 86
|

- Add a column `authenticated` to the tables `local_media_repository` and `remote_media_cache`
