Jean Paul, thanks for your suggestions, however, either -v or
--verbose yields an error: unknown switch `v'
regarding logs on the twisted side, I got this line at the top of the file:
log.startLogging(sys.stderr)
is there anything else I can do in order to expand the logging options.
anyway, once I changed the following:
def execCommand(self, proto, cmd):
command = ('git-shell', '-c', cmd)
shell = '/usr/bin/git-shell'
reactor.spawnProcess(proto, shell, command)
into:
def execCommand(self, proto, cmd):
command = ('git-shell', '-c', cmd)
shell = '/usr/bin/git-shell'
reactor.callFromThread(lambda: reactor.spawnProcess(proto,
shell, command))
Everything works fine. Seems like this separation did something good.
