- The benchmark addon now manages setting up and tearing down the backend and
traffic processes itself.
- Use wrk instead of hey. I get more consistent results with this tool, and hey
shows a strange tail-latency bump that seems artificial.
- Make termination behaviour simpler. The bencmark revealed a bug where .done
events were not called if the proxy was shut down by an addon.
There are a few reasons for this. First, logs are now async, and can be called
at any time. Second, the event loop is thread local, so there can only ever be
one master per thread. These two things together completely obviate the need
for a handler context.
Now that logs are async, using this call is almost always a mistake. Signal
this by making it semi-private. The method may go away entirely down the track.
Logs are now asynchronous, with a log entry pushed onto the event loop for
handling. To support this, the test mechanism grows an await_log method that
waits for a log entry to appear.
I have no idea why we did this, but the default value is 128, and setting it
this low drops connections under conditions our users can reasonably be expeted
to reach.
Also silence asyncio logs. We sometimes end up with messages on the queue that
need to be ignored when the proxy shuts down, and asyncio complains loudly
about this.
There are a number of significant improvements in Python3.6 - especially in
asyncio - that makes ditching Python 3.5 compelling. The next Ubuntu LTS will
be released before the next version of mitmproxy, and will include Python 3.6
in base.
This patch removes support for testing under Python 3.5 and changes our
documentation. There are deeper changes in the type system and so forth that we
will make over time.
We now acquire the event loop through asyncio.get_event_loop, avoiding having
to pass the loop explicity in a bunch of places. This function does not return
the currently running loop from within coroutines in versions of Python prior
to 3.6.
