I'm seeing more and more disasters with people failing to identify users correctly due to case sensitive IDs. For instance Amandine's business cards say @amandine:matrix.org whereas she's registered as @Amandine:matrix.org.

If we want any level of flexibility for this lookup we need the HS to implement mapping from printed user-id to actual matrix ID.
|
|
|
|
Unless we restrict the space of IDs to fit into ASCII then rigorously defining a case insensitive match is slightly painful.

The current plan of action on this (as discussed IRL yesterday evening is):
|
|
|
|
* Store IDs case-sensitively in the DB
|
|
* Compare them case-sensitively in the code & protocol
|
|
* Canonicalise them either at the origin client or origin HS by querying a lookup API on the destination HS (as per SPEC-62). This adds a roundtrip, but it may be suppressable by combining with some other roundtrip.
|
|
|
|
Open questions are:
|
|
* Do you do the canonicalisation lookup from the origin client (yet another random thing to expect clients to remember to do, which they will never remember to)
|
|
* Do you do the canonicalisation lookup from the origin HS?
|
|
* Do you use a user alias->id (assuming user aliases were separated from underlying IDs) lookup to also perform the canonicalisation?
