commit 5114e3e44235ea39447eea37213c65413cdb1a2c Author: Sebastian Hahn sebastian@torproject.org Date: Thu Apr 14 20:04:39 2011 -0700

Make SIGNAL DUMP work on FreeBSD

While doing so, get rid of the now unnecessary function control_signal_act().

Fixes bug 2917, reported by Robert Ransom. Bugfix on commit 9b4aa8d2abbce71398e58188209a1b1d04885b96. This patch is loosely based on a patch by Robert (Changelog entry). --- changes/bug2917 | 4 ++++ src/or/control.c | 3 ++- src/or/main.c | 43 +------------------------------------------ src/or/main.h | 2 +- src/or/or.h | 2 +- 5 files changed, 9 insertions(+), 45 deletions(-)
