From 9048fe1c50499d562dcf73094f173b12bdb084c4 Mon Sep 17 00:00:00 2001 From: Petr Baudis Date: Sat, 24 Sep 2005 16:13:01 +0200 Subject: [PATCH] [PATCH] git-daemon --syslog to log through syslog Well, this makes it even more clear that we need the packet reader and friends to use the daemon logging code. :/ Therefore, we at least indicate in the "Disconnect" log message if the child process exitted with an error code or not.
