[imapfilter-devel]Segmentation faults using rmove and rcopy

Thu Nov 7 04:00:01 EET 2002

The problem is back, this time I'm more able to catch it.

It is definitely tied to an individual message; here's what I have.

First note - this is on Solaris 8, with a couple of changes made to the 
config file:

> bash-2.03$ diff config /tmp/imapfilter-0.8.3-solarisport/config
> 15c15
> < libs=""
> ---
> > libs="-lsocket -lnsl"
> 180c180
> < CC = cc
> ---
> > CC = gcc

Config (with no arguments) and a make later (ignoring repeated warnings 
of "warning: assignment makes pointer from integer without a cast" 
during compile), I run imapfilter and get a segmentation fault just 
after it announces that it has moved 12 messages.

> bash-2.03$ ./imapfilter
> imapfilter: removing stale lockfile
> Enter master passphrase:
> Connected to (imap server).
> 6 messages, 0 recent, 0 unseen, in mailbox "INBOX".
> (cut)
> 12 messages, 0 recent, 11 unseen, in mailbox "INBOX.Junk".
> 12 messages moved to mailbox "INBOX.Junk" at account afterburner.
> Segmentation Fault

I rerun config with debug on and now my segmentation fault is right 
after it processes the first filter in the config file.

> debug: FOLDER: 'ako_fromhqda'
> debug: MBOX: 'fromhqda'
> debug: FILTER: 'older-60-del' AND
> debug: MASK: 'BEFORE 07-Sep-2002'
> Segmentation Fault

and here are the lines from the config file:

> account ako rick.nyman@***** ssl3
>   folder ako_inbox Inbox
>   folder ako_fromhqda fromhqda
>
> #Filters
>
> filter older-60-del and
>   older 60
> action delete
>
> filter older-007-unarchive and
>   older 007
> action move INBOX

I tried commenting out the older-60-del filter and I now get a crash on 
the following line:

> debug: MBOX: 'fromhqda'
> debug: FILTER: 'older-007-unarchive' AND
> debug: MASK: 'BEFORE 30-Oct-2002'
> Segmentation Fault

I then went to the website and downloaded the CVS tarball (the download 
link was 
http://cvs.hellug.gr/cgi-bin/viewcvs.cgi/imapfilter/imapfilter/imapfilter.tar.gz?tarball=1 
just to verify that I pulled the right thing).

Config with debug turned off yielded a crash at the same place as the 
original binary.  Turning debug on also crashed at the same place as the 
8.3 source - right after reading the last line of the config.

Now I delete every line of the config that is not necessary for the 
rmove to run and it looks like I got good results:

> bash-2.03$ ./imapfilter
> debug: configuration file: '/export/home/rick/.imapfilterrc'
> (cut)

I hope that this is helpful - in the past, I have been able to move the 
messages with Mozilla, but I'm holding off on touching this for the 
moment incase I need to do any more testing.

I can do tcpdump/ethereal dumps/traces if needed, and am happy to do any 
other necessary troubleshooting.

Since this is just a SPAM management folder, I'll disable that filter 
and leave the messages there for now.

I hope that I trimmed the right amount; I'm trying to keep the 
information intact while keeping this message short (I failed at the 
latter).

Thanks to all who support IMAPfilter and I hope this helps,
-Rick...
