Oh, no.
Silent format replacement should be performed only if source format is exactly default gunicorn log format, %(h)s %(l)s %(u)s %(t)s "%(r)s" %(s)s %(b)s "%(f)s" "%(a)s" according to the doc.
For all other gunicorn-styled but not default formats ValueError should be raised.

Ha, now I got you. The comment in issue was unclear to me. Going to fix this according to your input. Thanks!

Seems this is done. Also added a note to docs "Logging" section.

Please append http://aiohttp.readthedocs.io/en/stable/logging.html#format-specification link to exception text.
Now exception states that something is wrong but doesn't point on solution.
But it's most likely configuration problem, not programming error.
The exception will be caught by admin or devops, not software developer.
I suggest to provide very detailed error info in these cases.

Agreed. Thanks for the point. Added a link and a text with correct directive.
- Replace default gunicorn's access log format with the default aiohttp's
one.
- Use regular expression to check if the log format passed as a gunicorn's
option `access_logformat` uses Gunicorn's formatting style and in this case
raise a `ValueError`.
- Add a note describing this behavior to the `Logging` section of the
documentation.

What do these changes do?
It's intended to check
GunicornWebWorker.cfg.access_log_format.If its value is default Gunicorn's format string, it will be replaced with default aiohttp's log format string to create request handler with.
If it doesn't use default Gunicorn's format string but still sticks to Gunicorn's specification with format options in form of
%(name)s, theValueErrorwill be thrown with an appropriate message.Loggingsection of the documentation.Are there changes in behavior for the user?
Should fix #705 and show correct output in the access log.
