The previous method of spinning up a transient thread to import the
service pool in a child context could deadlock with use of the importer
on the main thread. Therefore wake the main thread to handle import for
us, and use a regular Receiver to buffer messages to the stub, which is
inherited rather than replaced by the real service pool.
Previously given something like:
l = mitogen.core.Latch()
l.put(1)
l.put(2)
s = mitogen.select.Select([l], oneshot=False)
assert 1 == s.get(block=False)
assert 2 == s.get(block=False)
The second call would throw TimeoutError, because Select.add() only
queued the receiver/latch once if it was non-empty, rather than once for
each item as should happen.
Its functionality was duplicated by _on_broker_exit() somewhere along
the way, and nothing has referred to it in a long time. I have no idea
how this happened.
Merge its docstring into _on_broker_exit() and delete it, remove the
Router "shutdown" signal after confirming it has no users, and move all
the Router-originated error messages together in a block at the top of
the class.
Already covered by router_test.AddHandlerTest.test_dead_message_sent_at_shutdown
Stream.set_protocol() was updated to break the reference on the previous
protocol, to encourage a crash should an old protocol continue operating
after it's not supposed to be active any more.
That broke DelimitedProtocol's protocol switching functionality.
Given a message sent on "ssh.foo" to "mypkg.mymod", instead of logging
it to "mitogen.ctx.ssh.foo" in the master process, with the message
prefixed with the original logger name, instead log it to
"mypkg.mymod.[ssh.foo]", permitting normal logging package filtering
features to work as they usually do.
This also helps tidy up logging output a little bit.
It's no longer necessary, since connection attempts are no longer truly
blocking. When CTRL+C is hit in the top-level process, broker will begin
shutdown, which will cancel all pending connection attempts, causing
pool threads to wake. The pool can't block during shutdown anymore.
