Summary: memory leaks patch
Description:
I did some digging in the current svn trunk and discoverd a few memory
leaks. I was able to create a patch for them, However there is one I have
found that doesn't have an easy fix. That is build_args_array_ext function
in imap session code. I wille attache to this report and valgrind
suppressions file to help in narrowing down the memory leaks or any other
issues in dbmail, this supresses a whole bunch of mess from glib and
gmime.
This is still includes the fix for authsql memleak as it doesn't appear
that it got into svn trunk. I added a check before db_query that looks for
unfreeed result sets and frees them automaticaly to avoid this in the
future.

Aarron or Paul have you guys had a chance to look at this? And maybe the
dbmail.supp file will help you with your sieve code..etc. Oh there is a
proccess in which you can debug/memcheck dbmail in your working directory
without re-compiling to static.
when you finish building your working directory, run dbmail-<daemon> -n
once and then exit it. you will find in .libs/lt-dbmail-<daemon> which
then can be passed to gdb and or valgrind memcheck:
e.g.
valgrind --suppressions=dbmail.supp --tool=memcheck --leak-check=full
--show-reachable=yes .libs/lt-dbmail-pop3d -n
or if you want to accualy watch it in deamon mode set your dbmail.conf
down to 2 children and run:
valgrind --suppressions=dbmail.supp --tool=memcheck --leak-check=full
--show-reachable=yes --trace-children=yes --log-file=/tmp/valtrace
libs/lt-dbmail-pop3d
this will make after a exit a file /tmp/valtrace.<masterpid> that will
have the memory debugging in it.
Thanks,
Leif
p.s. Paul any ideas on the x86_64 issue?

I've been using the dbmail.supp file this week, and it's really useful.
Thanks!
I admit that I haven't looked at the patch at all until just now; it's
fairly short, so I'll go over it this evening. Thanks again!
