[pkg-fetchmail-maint] Bug#502381: --idle should care about expunging.

[Trent W. Buck]

Package: fetchmail
Version: 6.3.9~rc2-3
Severity: minor

I'm interested in (ab)using fetchmail as a kind of imap biff -- that
is, I want it to print a line whenever the number of \seen mail in my
IMAP inbox changes.  This nearly works with fetchmail --check --idle,
but unfortunately it doesn't update when I *remove* mail INBOX:


    $ fetchmail --check --idle --verbose
    [...]
    11 messages for trentbuck at imap.gmail.com.
    fetchmail: IMAP> A0022 IDLE
    fetchmail: IMAP< + idling
    fetchmail: IMAP< * 11 EXISTS
    fetchmail: IMAP> DONE
    fetchmail: IMAP< A0022 OK IDLE terminated (Success)
    fetchmail: IMAP> A0023 IDLE
    fetchmail: IMAP< + idling
    fetchmail: IMAP< * 11 EXISTS
    fetchmail: IMAP> DONE
    fetchmail: IMAP< A0023 OK IDLE terminated (Success)
    fetchmail: IMAP> A0024 IDLE
    fetchmail: IMAP< + idling
    fetchmail: IMAP< * 9 EXPUNGE
    fetchmail: IMAP< * 11 EXISTS
    fetchmail: IMAP> DONE
    fetchmail: IMAP< A0024 OK IDLE terminated (Success)

    fetchmail: IMAP> A0025 IDLE
    fetchmail: IMAP< + idling
    fetchmail: IMAP< * 5 EXPUNGE
    fetchmail: IMAP< * 5 EXPUNGE
    fetchmail: IMAP< * 5 EXPUNGE
    fetchmail: IMAP< * 5 EXPUNGE

    fetchmail: IMAP< * 5 EXPUNGE
    fetchmail: IMAP< * 4 EXISTS
    fetchmail: IMAP> DONE
    fetchmail: IMAP< A0025 OK IDLE terminated (Success)

It ought to print "4 messages ..." here!

    fetchmail: IMAP> A0026 IDLE
