Subject:

uninitialized value in concatenation upon list()

hi paul et al, $imap->list() throws a bunch of copies of the following error message after i created two mailboxes with unholy names: ":: Portuguese" and ">>> Romanian". (i was searching for a way to get them sorting apart from other boxes in the mail client.) the trace from perl -d: Use of uninitialized value in concatenation (.) or string at /home/abrick/mts/spamapps-mts-1.0.0.520/opt/spamengine/lib/Net/IMAP/Simple.pm line 449. at /home/abrick/mts/spamapps-mts-1.0.0.520/opt/spamengine/lib/Net/IMAP/Simple.pm line 449 Net::IMAP::Simple::list('Net::IMAP::Simple=HASH(0x9df1e38)') called at ./MRT.pm line 202 ... i'm on perl 5.8.8 on linux 2.6.9-42, centOS i think.

Hi. I can probably try to recreate this, but it would be helpful if you could turn on the debugging (use debug=>"file:mylog.log" in the new() call) and attach relevant portions of that. I suspect it's not grabbing the folder names right because of the non-alpha symbols. This module doesn't have a very robust parser (yet) so it may not be possible to get everything perfectly correct, but we can probably do a better job than it's doing. -Paul -- If riding in an airplane is flying, then riding in a boat is swimming. 116 jumps, 48.6 minutes of freefall, 92.9 freefall miles.

I don't have a path to decode the winmail.dat file. I have figured that format out, but it was many years ago. I don't suppose you could attach it in cleartext? -- If riding in an airplane is flying, then riding in a boat is swimming. 116 jumps, 48.6 minutes of freefall, 92.9 freefall miles.

i am quite confused how anything called winmail.dat got in this thread. maybe my company's horrible "outlook web access" reencoded the log file in a weird way? i am reattaching the same log content as a .txt and using the rt.cpan.org interface. let me know if there is any issue with what's in here, or if i have misunderstood the problem.

I flipped through this logfile and I don't see any >>>>, any ::, nor any errors associated with those folder names. I then connected to gmail and issued an $imap->create_mailbox(">>>> lol"), issued $imap->copy("1:10"=>">>>> lol"), then did an $imap->select(">>>> lol") and got "10". I then did an $imap->delete_mailbox(">>>> lol") and everything seemed to go swimmingly. I do see some errors in that logfile, but none that relate to folder names. It looks like, mostly you're trying to use message sets like "1:0" and "1:" which are always invalid. Try "1:10" or "1:*" or something that makes sense to your imap server and you should be all set. -Paul -- If riding in an airplane is flying, then riding in a boat is swimming. 116 jumps, 48.6 minutes of freefall, 92.9 freefall miles.

paul, thank you for looking into my log file, and sorry my ascription of the problem to the box names was in error. i can't reproduce the problem any more, though i don't think i was doing anything suspect - every time i specified a message its ID comes from the output of the list() operation. maybe our IMAP system (imap.everyone.net, FWIW) was returning problematic message IDs that looked like "1:0". i appreciate your support and hope you are having fun with your new baby! aaron.

doing anything suspect - every time i specified a message its ID comes from the output of the list() operation. maybe our IMAP system (imap.everyone.net, FWIW) was returning problematic message IDs that looked like "1:0". I suspect the mailbox was just empty then. If you don't specify a number as an argument to list(), it attempts to list the sizes of all the messages in the box. But it does it stupidly (which I think I'll fix) so that if there's 0 messages in the box it looks for 1:0. Really, it should always use '1:*' rather than "1:" . $self->_last for just this reason. -Paul -- If riding in an airplane is flying, then riding in a boat is swimming. 116 jumps, 48.6 minutes of freefall, 92.9 freefall miles.

The above doesn't fix it either... but it *is* fixed in 1.2016 -Paul -- If riding in an airplane is flying, then riding in a boat is swimming. 116 jumps, 48.6 minutes of freefall, 92.9 freefall miles.
