497598 - hang on shutdown appending msg to imap folder via a filter

Status: VERIFIED FIXED

(MailNews Core :: Networking: IMAP, defect)

Attachment: proposed fix

I have a filter that copies incoming pop3 mail to an imap folder - if I shutdown at the wrong time, it hangs because the underlying temp file that's getting appended gets removed, and we spin reading 0 bytes from the file input stream.

The underlying file shouldn't be getting removed (rkent is working on fixing that, I think), but we shouldn't be getting 0 bytes back from the file inputstream either, and I think bailing out here is better than spinning.

this hits me often enough that it's worth trying to fix.

This needs a different fix - Wayne is having this problem in the real world, and I've got a different possible fix.

Attachment: different fix

we should be checking for the zero length file before we start issuing protocol.

I've requested a try server build with the above patch so Wayne can see if it fixes his problem.
