proxy: remove unneeded _set_hostport for compatibility with Python 2.7.7rc1 With Python 2.7.7rc1, "hg pull" through HTTP CONNECT tunnel fails due to the removal of _set_hostport [1]. ... File "mercurial/url.py", line 372, in https_open return self.do_open(self._makeconnection, req) ... File "mercurial/url.py", line 342, in connect _generic_proxytunnel(self) File "mercurial/url.py", line 228, in _generic_proxytunnel self._set_hostport(self.host, self.port) AttributeError: httpsconnection instance has no attribute '_set_hostport' self._set_hostport(self.host, self.port) should be noop and can be removed because: - _set_hostport() [2] was the function to parse "host:port" string and set them to self.host and self.port, - and (self.host, self.port) pair should be valid since connect() is called prior to _generic_proxytunnel().

"""Extension to verify locks are obtained in the required places.

This works by wrapping functions that should be surrounded by a lock
and asserting the lock is held. Missing locks are called out with a
traceback printed to stderr.

This currently only checks store locks, not working copy locks.
