* This commit adds handlers for the asyncio/uvloop protocol callbacks for pause_writing and resume_writing.
These are needed for the correct functioning of built-in tcp flow-control provided by uvloop and asyncio.
This is somewhat of a breaking change, because the `write` function in user streaming callbacks now must be `await`ed.
This is necessary because it is possible now that the http protocol may be paused, and any calls to write may need to wait on an async event to be called to become unpaused.
Updated examples and tests to reflect this change.
This change does not apply to websocket connections. A change to websocket connections may be required to match this change.
* Fix a couple of PEP8 errors caused by previous rebase.
* update docs
add await syntax to response.write in response-streaming docs.
* remove commented out code from a test file
* Fix two problems with the auto_reloader in Linux.
1) Change 'posix' to 'linux' in sys.plaform check, because 'posix' is an invalid value and 'linux' is the correct value to use here.
2) In kill_process_children, don't just kill the 2nd level procs, also kill the 1st level procs.
Also in kill_process_children, catch and ignore errors in the case that the child proc is already killed.
* Fix flake8 formatting on PR
The Canceled exception handler purposely sets `response` to `None` to drop references to the handler coroutine, in an attempt to preemptively release resources.
This commit also fixes a possible reference-before-assignment of the `response` variable in the `handle_request` function.
Finally, another byproduct of this change is that ResponseMiddleware will no longer run if the `response` is `None`.
* Add content_type flag to Sanic.static
Fixes#1266
* Fix flake8 error in travis
Add line to document `content_type` arg
* Fix content_type for file streams
Update tests

* Remove content_type as an arg to HTTPResponse
`response.HTTPResponse` will default to `headers['Content-Type']` instead of `content_type`

* URL Quote the URL before redirecting
* Use safe url instead of unsafe one
* Fix query params
* fix build
* Whitelist all reserved characters from rfc3986
* Add tests for redirect url sanitizing
* Remove check for resulting URL on header injection test
The thing the tests are testing for can be implemented in other
ways that don't redirect to 100% the same address, but they'll all have
to match the remaining parts of the test to succeed.
