commit b3133d1cadec0540105a855b1fd2eb741d4eec9d Author: Robert Ransom rransom.8774@gmail.com Date: Mon May 16 10:25:59 2011 -0700

Exit immediately if we can't monitor our owning controller process

tor_process_monitor_new can't currently return NULL, but if it ever can, we want that to be an explicitly fatal error, without relying on the fact that monitor_owning_controller_process's chain of caller will exit if it fails. --- src/or/config.c | 5 +---- src/or/control.c | 20 ++++++++++---------- src/or/control.h | 2 +- 3 files changed, 12 insertions(+), 15 deletions(-)
