1701218 - Support message redactions

Status: RESOLVED FIXED

(Chat Core :: Matrix, enhancement)

Description

[Martin Giger [:freaktechnik]]

Matrix allows for events to be redacted (deleted). This leads to its content no longer being available to any participant. We currently don't handle redactions at all, and don't support sending them.

This would require a mapping of matrix event ID to the displayed message ID, as well as support for redactions in the conversation API.

A big question is how we would handle it in logs, since our logs are currently append-only.

I think this is mostly a special case of bug 1701216?

I guess in terms of UI support they would be fairly similar - except that as a moderator you would also be allowed to redact other's messages, while you don't get to edit other's messages.

I filed them separately primarily because they are separate events in the protocol (this is m.room.redaction).

I meant mostly in terms of the infrastructure necessary -- we need to be able to reach back into the DOM and modify a message after the fact, plus do something with the logs.
