Hello,
I'm use lighttpd+SPAWNFCGI for moinmoin wiki.
Before r274463 work fine, after update r275317 and CURRENT system
crushed after start any python CGI script.
For test i'm install py27-flup and start simple
#!/usr/local/bin/python2.7
def myapp(environ, start_response):
start_response('200 OK', [('Content-Type', 'text/plain')])
return ['Hello World!\n']
if __name__ == '__main__':
from flup.server.fcgi import WSGIServer
WSGIServer(myapp).run()
Perl CGI test script work fine.
Workaround FreeBSD-r275317 and later
lighttpd-1.4.35_5
