[Freevo-devel] freevo just doesn't die when my plugin is activated

[Michael R. <mik...@at...>]

Ok I am making progress on the new plugin for freevoweb. It starts. It
serves the cgi's but alas it causes freevo to never exit when it is
activated.

I add the following to local_conf.py

WWW_PORT = 8080
WWW_IP_ALLOW = ['192.168.1.3','192.168.1.2','127.0.0.1']
plugin.activate('web.PluginInterface')
 
i put this file in $FREEVO_STARTDIR/src/plugins/

see web.py attached

I have slightly modified webserver.py to be a little nicer about chdir.
I will eventually have it only serve the cgi's from the base directory
otherwise you never get the style sheet or gifs. (I.e. it will server
/htbin/guide.cgi, /cgi-bin/guide.cgi and /foobar/guide.cgi all of which
do horrible things to where we expect to find the css and only
/guide.cgi is right)

see webserver.py attached

So everything really works well until you try to /etc/init.d/freevo stop
or try to select shutdown from the ui menu.

it thinks it stops everything but ps -ef still shows freevo processes
(freevo_loader) still running and they don't die until you killall -9
freevo_loader

The webserver.py was written to be resilient and does a try, and except
which kills it for keyboard interupt and just restarts it if it does for
some other reason. So I figured that was the problem. So I commented out
the pass and put sys.exit. still doesn't work. The only clue about what
went wrong in the /etc/init.d/freevo stop case in the logfile is:

Traceback (most recent call last):
  File "src/main.py", line 330, in ?
  File "src/main.py", line 237, in signal_handler
  File "/usr/local/freevo/src/util.py", line 413, in killall
    print 'killall: Sending signal %s to pid %s ("%s")' % a
ValueError: I/O operation on closed file

and from the GUI it will hang like this:

killall: Sending signal 9 to pid 2428 ("./runtime/dll/freevo_loader
./runtime/apps/freevo_python src/main.py ")

In both cases, the GUI does go away on the screen but shutdown doesn't
seem to happen and this system will shutdown normally either way if I
comment out the plugin activation

Any help would be much appreciated. I know very little about python
threads (I do know how to do it in other languages).
