From 5c5f8134e5bbedf71a63e377d49c0962fe1ba1ad Mon Sep 17 00:00:00 2001 From: Guilhem Moulin Date: Wed, 9 Mar 2016 20:59:14 +0100 Subject: pullimap: keep trying to pull new messages after issuing any IMAP command. Indeed we might get an untagged EXISTS response, meaning that a new message has been received meanwhile. --- lib/Net/IMAP/InterIMAP.pm | 2 +- pullimap | 58 +++++++++++++++++++++++++++++------------------ 2 files changed, 37 insertions(+), 23 deletions(-) diff --git a/lib/Net/IMAP/InterIMAP.pm b/lib/Net/IMAP/InterIMAP.pm index bd69d87..bad49da 100644 --- a/lib/Net/IMAP/InterIMAP.pm +++ b/lib/Net/IMAP/InterIMAP.pm @@ -1053,7 +1053,7 @@ sub uidvalidity($;$) { } -# $self->set_cache(@attributes) +# $self->get_cache(@attributes) # Return the persistent cache for the mailbox currently selected.
