Subject [PATCH] Exec utility signal relay
Date Thu, 07 Dec 2006 21:25:30 GMT
Greetings all.

Attached is a patch that aims to resolve an old issue with the exec 
utility on UNIX.  The problem observed is that when a kill signal is 
sent to the exec utility, the child processes aren't killed.  This patch 
has been tested on Linux IA-32 and HPUX-11.23 on IA-64 (chosen due to 
previous issues with signals).

--Andrew Black

	* exec.cpp (alarm_timeout) [!_WIN32]: Update documentation.
	(kill_signal) [!WIN32]: Add file local variable to track signal used to
	kill process.
	(handle_term_signal) [!_WIN32]: Add new callback function...
	(wait_for_child) [!_WIN32]: ... Used here for SIGHUP, SIGINT, SIGQUIT,
	and SIGTERM signals (via sigaction).  Handlers are cleared if
	kill_signal is set and the signal contained within is raise()ed.
