Namespace Uniform.Matrix.Server.Storage

Classes

AccessTokenRow

An access token, stored as its SHA-256 hash so a leaked database does not leak sessions.

AccountDataRow

Account data of a user: global when RoomId is empty, else for one room.

CounterRow

A named counter of the server, such as the last ServerStream position.

CurrentStateRow

The current state of a room, one row per type and state key, for fast reads.

DataDirectoryInUseException

Another server process uses the data directory; stop it first.

Keeps other server processes off a data directory while this one uses it: LockFileName is held open exclusively, which on Linux is an flock that the kernel releases when the process ends, also when it is killed, so the lock never goes stale.

DatabaseMigrator

Creates or upgrades the schema at start, before the server accepts requests, in write-ahead log mode so reads do not block writes; and flushes the database at stop.

DelayedEventRow

A delayed event (MSC4140) waiting to be sent, kept so that a restart of the server does not forget it.

DesignTimeServerDbContextFactory

Context for dotnet ef at design time, on a throwaway SQLite file.

DeviceKeysRow

The signed device keys of a device, without signatures others uploaded later.

DeviceListChangeRow

The latest change of a user's devices or cross-signing keys, which others' syncs report in device_lists.changed.

DeviceRow

A device of a local user.

EventEdgeRow

Edge of the room graph: an event and one of its previous events.

EventRelationRow

A relation of an event to another, from its m.relates_to, for threads and relation lookups.

EventRow

An event of the room graph, stored as its PDU JSON without the event ID.

FallbackKeyRow

The fallback key of a device for one algorithm, given out when its one-time keys run out.

FederationOutboxRow

A PDU or EDU waiting to be sent to another server, kept so a restart does not lose it; deleted once sent or refused for good.

FederationProgressRow

How far the federation sender has handed the stream to its queue, so a restart continues there and misses nothing; one row.

FilterRow

A stored sync filter of a user.

ForgottenRoomRow

A room a user has forgotten, so it no longer shows in their sync.

ForwardExtremityRow

A forward extremity: an event of the room that no other event follows yet; new events point at these.

KeyBackupVersionRow

A key backup version of a user.

KeySignatureRow

A signature uploaded later for a device key or a master key, kept apart so each user sees only the signatures meant for them.

MediaRow

A file in the media repository, uploaded by a local user; the bytes are stored in the media directory.

OneTimeKeyRow

An unclaimed one-time key of a device.

ProfileRow

A user's profile.

PusherRow

A pusher: where to send push notifications of a user, usually a push gateway that wakes a phone app.

ReceiptRow

A user's latest receipt of one type and thread in a room.

RegistrationTokenRow

A registration token an admin created, as Synapse's admin API manages them.

RemoteInviteRow

An invite from another server to a room not on this server yet, with the room's stripped state; joining the room or rejecting the invite ends it.

RemoteMediaRow

Media of another server, fetched once and kept here; its file and thumbnails are stored under LocalId, an ID of this server, as other servers' IDs are not safe as paths.

ReportRow

A user's report of an event, room or user, for the admin to review.

RoomAliasRow

A local room alias.

RoomKeyRow

A backed-up room key of one session.

RoomRow

A room known to the server.

ServerDbContext

The homeserver's database; SQLite now, PostgreSQL later through the same model.

ServerKeyResponseRow

Another server's signed key answer, as /_matrix/key/v2/server gave it, kept so a restart or a server that is down does not stop checking its signatures; the latest per server.

StateGroupEntryRow

One state entry of a state group.

StateGroupRow

A room state snapshot, stored as changes against a parent group.

ThumbnailRow

A generated thumbnail of a MediaRow, stored next to it.

ToDeviceRow

A to-device message waiting for its device's next sync.

TransactionRow

A client transaction ID mapped to the event it created, so retried sends are not duplicated.

UserRow

A local user account.
