Hi,
I have a python script that calls macros in OpenOffice.org like this:
---------------------
....
localContext = uno.getComponentContext()
resolver =
localContext.ServiceManager.createInstanceWithContext("com.sun.star.bridge.UnoUrlResolver",
localContext)
try:
ctx =
resolver.resolve("uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext")
except:
print "\nSome error message..."
sys.exit(1)
smgr = ctx.ServiceManager
desktop = smgr.createInstanceWithContext("com.sun.star.frame.Desktop", ctx)
dispatcher =
smgr.createInstanceWithContext("com.sun.star.frame.DispatchHelper", ctx)
dispatcher.executeDispatch(desktop, macro, "", 0, ())
ctx.ServiceManager
---------------------
But, some times openoffice.org crashes and hangs. Then this python script
hangs on
"dispatcher.executeDispatch(desktop, macro, "", 0, ()) "
So I tried to put an alarm around it like this:
----------------------
def handle_timeout(signum, frame):
print 'Timeout!'
sys.exit(1)
old = signal.signal(signal.SIGALRM, handle_timeout)
signal.alarm(1)
try:
dispatcher.executeDispatch(desktop, macro, "", 0, ())
finally:
signal.alarm(0)
signal.signal(signal.SIGALRM, old)
-----------------------
>From strace, I can see that the alarm signal is sent, but it looks like the
signal is masked, and the script does not print "Timeout!", and it does not
exit.
If OpenOffice.org is not alive, I want to kill OpenOffice and restart the
scirpt. How can I check that OpenOffice.org is alive?
I tried to check what OpenOffice.org was doing, but no luck:
$ ps aux | grep -i soffice.bin
