Prevent hanami-unicorn from logging each request (#3076)
Prior to this change, hanami-unicorn would print something like this
to the log on each incoming request:
Server hanami-unicorn: 204.93.249.210 - - [13/Nov/2017:01:03:18 -0600]
"GET HTTP/1.0" 200 31 0.0038
This looks a lot like an nginx access log, but it isn't (notice the
"0.0038" at the end where nginx would usually write the user agent).
I think this is actually coming form unicorn's request log, and that's
being enabled by some Rack middleware component that's being pulled in
automatically somewhere. Setting the RACK_ENV environment variable to
"none" apparently disables this middleware, and it does get rid of these
particular log messages, so that's the change I've made here.
For more background, see this unicorn documentation:
https://bogomips.org/unicorn/unicorn_1.html#rack-environment
I'm looking at this part specifically:
Accepted values of RACK_ENV and the middleware they automatically
load (outside of RACKUP_FILE) are exactly as those in rackup(1):
* development - loads Rack::CommonLogger, Rack::ShowExceptions,
and Rack::Lint middleware
* deployment - loads Rack::CommonLogger middleware
* none - loads no middleware at all, relying entirely on RACKUP_FILE
