Package: offlineimap Version: 5.99.1 Severity: normal I just tried a new mail reading model which involves storing all my mail in a single folder. I am not yet convinced this is the right way to do it, but in any case: offlineimap can't really deal with it.
Right now, the folder contains 67k messages, and messages get added
locally most of the time (and thus have to be copied to the server).
I've always noticed that, despite asymmetric bandwidth, pushing
messages to the server always takes longer than pulling them, but
with 67k messages in the folder, the performance is now neigh
unacceptable, sometimes taking up to a minute for a single message.
Note that all messages are a few kilobytes only.

Please find the complete -1 -d imap,maildir log and strace at [0]
and [1] (they are too large to be attached; also please note that
these links expire 60 days after the last access) limited only to
this one Maildir:
strace -t -T -o /tmp/offlineimap.strace \
/usr/bin/offlineimap -1 -d imap,maildir -l /tmp/offlineimap.debuglog

In this run, three messages are pushed to the server and the S flag
is added to 12k messages, which times out after a really long time:
Adding flags S to 11998 messages on IMAP[store]
Adding flags S to 11998 messages on LocalStatus[store]
imap(madduck): Info: Disconnected for inactivity
After the first two messages, the debuglog received absolutely zero
data, while strace seems to document some sort of deadlock
situation. The loop captured by strace continues to spin though.
