Ugh. I *knew* I previously read somewhere that UID was required for
|
|
all FLAGS responses after QRESYNC was activated. I was going to check
|
|
the errata before sending out my original message, but got distracted.
|
|
|
|
And there is still a gap in coverage when only CONDSTORE is available
|
|
(or a server implementation of QRESYNC that doesn't follow the errata)
|
|
- you can still receive untagged FLAGS responses that contain MODSEQ
|
|
but not UID data:
|
|
|
|
a SELECT INBOX (CONDSTORE)
|
|
[...]
|
|
* 3 EXISTS
|
|
* OK [HIGHESTMODSEQ 5] Highest
|
|
a OK [READ-WRITE] SELECT completed.
|
|
b UID FETCH 5 (UID)
|
|
* 1 FETCH (UID 5)
|
|
* 2 FETCH (FLAGS (\Seen) MODSEQ (6))
|
|
* 3 FETCH (FLAGS (\Seen) MODSEQ (6) UID 15)
|
|
b OK FETCH completed.
|
|
|
|
Granted, this isn't likely from a practical standpoint, but it is a
|
|
possibility. And one I probably haven't considered in my code. Arrgh.
