source: variable.c @ 0d5d51b

Last change on this file since 0d5d51b was 2fa15f0, checked in by Alejandro R. Sedeño <asedeno@mit.edu>, 18 years ago
1) Fix massive memory leak. I've removed the variable that held the mainloop hook name, replacing the two references to it with the hard-coded function "owl::mainloop_hook". We were discussing doing this anyhow, and since leak was in getting the variable over and over again, this was the easiest way to deal. 2) Updated owlconf.pl in light of (1). Update your local copy! 3) jabber - groupchat history is not requested, and is explicitly ignored.
