David Wilson 0f63ca4c68 Make setting affinity optional. 5 years ago
David Wilson 9035884c77 ansible: abstract worker process model.
Move all details of broker/router setup out of connection.py, instead
deferring it to a WorkerModel class exported by process.py via
get_worker_model(). The running strategy can override the configured
worker model via _get_worker_model().

ClassicWorkerModel is installed by default, which implements the
extension's existing process model.

Add optional support for the third party setproctitle module, so
children have pretty names in ps output.

Add optional support for per-CPU multiplexers to classic runs.

David Wilson 6b8a7cbcc4 [stream-refactor] parent: fix crash on graceful shutdown
Now it's possible for stream.protocol to not refer to MitogenProtocol,
move the signal handler to a MitogenProtocol subclass instead.

Fixes a crash where CTRL+C during child bootstrap would print
AttributeError.

David Wilson 4e6aadc40a [stream-refactor] fix LogHandler.uncork() race
During early initialization under hackbench, it is possible for Broker
to be in LogHandler._send() while the main thread has already destroyed
_buffer. So we must synchronize them, but only while the handler is
corked.

David Wilson 90c989ee59 [stream-refactor] BufferedWriter must disconenct Stream, not Protocol
Fix a race where if Stream.on_receive() detects disconnect, it calls
Stream.on_disconnect(), which fires Stream 'disconnect' event, whereas
if BufferedWriter.on_transmit() detects disconnect, it called
Protocol.on_disconnect(), which did not fire the Stream 'disconnect'
event.

Since mitogen.parent listens on Stream's 'disconnect' event to reap
children, this was causing a very difficult to trigger test failure.

Triggered after <1000 runs on a Xeon E5530 with hyperthreading using
hackbench running at the same priority:

    $ hackbench -s 1048576 -l 100000000000 -g 4

David Wilson 2f950b3bda [stream-refactor] allow doas_test to succeed on CentOS
Unlike on Debian, some environment variables that tickle
getpass.getuser() are being inherited. So use getuid() instead.

Also install the doas binary on CentOS. CI was changed (I believe) to
shrink the configuration matrix, and now these tests run on CentOS too.

David Wilson 300f8b2ff9 ansible: fixturize creation of MuxProcess
This relies on the previous commit resetting global variables.

Update clean_shutdown() to handle duplicate calls, due to tests
repeatedly installing it.

David Wilson 6e33de7cd2 unix: ensure mitogen.context_id is reset when client disconnects
To ensure a test process can successfully recreate an Ansible
MuxProcess, reset fork-inherited globals during disconnection.

There is basically no good place for this. Per the comments on #91, it
would be far better if the context's identity was tied to its router,
rather than some global variable.
