- Ignore the NotImplementedError raised by add_signal_handler on Windows.
- Entrypoints return an integer exit code, or None. Adjust our type annotations
and code to suit.
Fixes#3061
- 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.
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.
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.
This is a preparatory patch that paves the way to consolidating our core
options in the core addon. It amalgamates the core_option_validation and core
addons, prepares the test suite for a world where options live in core, and
moves over two trivial options as a trial balloon.
From here, things will get harder, but at the end of the process we'll have a
core that's responsive to options.
Split verbosity into termlog_verbosity and console_eventlog_verbosity.
This patch also removes printing to console if there are unknown options in the
command-line. Options now live in separate addons, so having uknown options
remaining is common and expected. We definitely shoould have some other way for
users to see what was ignored so they can catch typos and the like, but that's
a different patch.
