Tweak testsuite timeouts. Move garb timers around so that the debug

request start_garb() can actually start the garb.  Fixes breakage in
lyskomd.0/09.exp.  Use the liboop signal adapter; avoid using
siglongjmp from signal handlers.  Ignore signals during shutdown.  Fix
errors in ths liboop signal adapter.

ChangeLog

 2003-07-13  Per Cederqvist  <ceder@ceder.dyndns.org>
 
+	Tweak testsuite timeouts.
+	* src/server/testsuite/config/unix.exp (timeout): Increase the
+	timeout 2 more seconds.
+
+	Move garb timers around so that the debug request start_garb() can
+	actually start the garb.  Fixes breakage in lyskomd.0/09.exp.
+	* src/server/text-garb.h (garb_text): This function is now
+	static.
+	(start_garb_thread): New function.
+	(stop_garb_thread): New function.
+	* src/server/text-garb.c (garb_timer): New static variable.
+	(garb_timer_running): Ditto.
+	(garb_text): Added static qualifier.
+	(garb_callback): Moved here from connections.c.  Some minor
+	modifications made to make it compiler in its new environment.
+	(start_garb_thread): New function.
+	(stop_garb_thread): New function.
+	(start_garb): Restart the garb "thread".
+	* src/server/connections.h (set_time): Now exported.
+	(setup_timer): Ditto.
+	(server_idle): New function.
+	* src/server/connections.c (set_time): No longer static.
+	(setup_timer): Ditto.
+	(garb_callback): Moved to text-garb.c. 
+	(saver_callback): The source argument is actually used.
+	(toploop): Moved the garb timer to text-garb.c.
+	(server_idle): New function.
+
+	Use the liboop signal adapter; avoid using siglongjmp from signal
+	handlers.  Ignore signals during shutdown.
+	* src/server/ramkomd.c (kom_signal_adapter): New static variable.
+	(server_init): Use oop_signal_new, since I don't trust the way
+	liboop uses siglongjmp to break out of a signal handler.  Ignore
+	the signals before registering them with liboop, to get a proper
+	behaviour on shutdown.
+	(main): Adjusted to use the signal adapter.
+
+	Fix errors in ths liboop signal adapter.
+	* src/libraries/liboop/signal.c (use_sa_restart): New static
+	variable.
+	(sig_on_signal): Add SA_RESTART if appropriate.
+	(oop_signal_new): Don't just blindly set FD_CLOEXEC and
+	O_NONBLOCK.  Read the old settings first.
+	(oop_signal_use_sa_restart): New function.
+	* src/libraries/liboop/oop.h (oop_signal_use_sa_restart): New
+	function.
+
 	Updated documentation for the configuration file for "timeval"
 	parameters and penalty points/client scheduling.
 	* doc/lyskomd.texi (Parameter Types): Document "timeval".
