irctest.server_tests.read_marker

Read marker set in one session persists when reconnecting.

When a user sets a read marker, the server SHOULD send MARKREAD to

all other sessions of the same user that have the capability negotiated.

MARKREAD get on a target with no stored timestamp returns '*'.

MARKREAD set with a malformed timestamp → FAIL MARKREAD INVALID_PARAMS.

MARKREAD with no parameters → FAIL MARKREAD NEED_MORE_PARAMS.

If a client sends a MARKREAD with an older timestamp, the server MUST

reply with the newer stored value (spec: 'The last read timestamp of a target MUST only ever increase').

After JOIN, server MUST send MARKREAD before RPL_ENDOFNAMES (366).

After JOIN, MARKREAD sent by server reflects any previously stored timestamp.

MARKREAD get for a user (DM) target returns the stored value.

MARKREAD get after a set returns the stored timestamp.

MARKREAD client set command MUST NOT use '*' as the timestamp.
