Streaming Server (#1876)
* Streaming request by async for.

* Make all requests streaming and preload body for non-streaming handlers.

* Cleanup of code and avoid mixing streaming responses.

* Async http protocol loop.

* Change of test: don't require early bad request error but only after CRLF-CRLF.

* Add back streaming requests.

* Rewritten request body parser.

* Misc. cleanup, down to 4 failing tests.

* All tests OK.

* Entirely remove request body queue.

* Let black f*ckup the layout

* Better testing error messages on protocol errors.

* Remove StreamBuffer tests because the type is about to be removed.

* Remove tests using the deprecated get_headers function that can no longer be supported. Chunked mode is now autodetected, so do not put content-length header if chunked mode is preferred.

* Major refactoring of HTTP protocol handling (new module http.py added), all requests made streaming. A few compatibility issues and a lot of cleanup to be done remain, 16 tests failing.

* Terminate check_timeouts once connection_task finishes.

* Code cleanup, 14 tests failing.

* Much cleanup, 12 failing...

* Even more cleanup and error checking, 8 failing tests.

* Remove keep-alive header from responses. First of all, it should say timeout=<value> which wasn't the case with existing implementation, and secondly none of the other web servers I tried include this header.

* Everything but CustomServer OK.

* Linter

* Disable custom protocol test

* Remove unnecessary variables, optimise performance.

* A test was missing that body_init/body_push/body_finish are never called. Rewritten using receive_body and case switching to make it fail if bypassed.

* Minor fixes.

* Remove unused code.

* Py 3.8 check for deprecated loop argument.

* Fix a middleware cancellation handling test with py38.

* Linter 'n fixes

* Typing

* Stricter handling of request header size

* More specific error messages on Payload Too Large.

* Init http.response = None

* Messages further tuned.

* Always try to consume request body, plus minor cleanup.

* Add a missing check in case of close_if_idle on a dead connection.

* Avoid error messages on PayloadTooLarge.

* Add test for new API.

* json takes str, not bytes

* Default to no maximum request size for streaming handlers.

* Fix chunked mode crash.

* Header values should be strictly ASCII but both UTF-8 and Latin-1 exist. Use UTF-8B to
cope with all.

* Refactoring and cleanup.

* Unify response header processing of ASGI and asyncio modes.

* Avoid special handling of StreamingHTTPResponse.

* 35 % speedup in HTTP/1.1 response formatting (not so much overall effect).

* Duplicate set-cookie headers were being produced.

* Cleanup processed_headers some more.

* Linting

* Import ordering

* Response middleware ran by async request.respond().

* Need to check if transport is closing to avoid getting stuck in sending loops after peer has disconnected.

* Middleware and error handling refactoring.

* Linter

* Fix tracking of HTTP stage when writing to transport fails.

* Add clarifying comment

* Add a check for request body functions and a test for NotImplementedError.

* Linter and typing

* These must be tuples + hack mypy warnings away.

* New streaming test and minor fixes.

* Constant receive buffer size.

* 256 KiB send and receive buffers.

* Revert "256 KiB send and receive buffers."

This reverts commit abc1e3edb21a5e6925fa4c856657559608a8d65b.

* app.handle_exception already sends the response.

* Improved handling of errors during request.

* An odd hack to avoid an httpx limitation that causes test failures.

* Limit request header size to 8 KiB at most.

* Remove unnecessary use of format string.

* Cleanup tests

* Remove artifact

* Fix type checking

* Mark test for skipping

* Cleanup some edge cases

* Add ignore_body flag to safe methods

* Add unit tests for timeout logic

* Add unit tests for timeout logic

* Fix Mock usage in timeout test

* Windows py3.8 logging issue with current testing client

* Add test_header_size_exceeded

* Resolve merge conflicts

* Add request middleware to hard exception handling

* Add request middleware to hard exception handling

* Request middleware on exception handlers

* Linting

Socket binding implemented properly for IPv6 and UNIX sockets. (#1641)
* Socket binding implemented properly for IPv6 and UNIX sockets.

- app.run("::1") for IPv6
- app.run("unix:/tmp/server.sock") for UNIX sockets
- app.run("localhost") retains old functionality (randomly either IPv4 or IPv6)

Do note that IPv6 and UNIX sockets are not fully supported by other Sanic facilities.
In particular, request.server_name and request.server_port are currently unreliable.

* Fix Windows compatibility by not referring to socket.AF_UNIX unless needed.

* Compatibility fix.

* Fix test of existing unix socket.

* Cleaner unix socket removal.

* Remove unix socket on exit also with workers=1.

* More pedantic UNIX socket implementation.

* Refactor app to take unix= argument instead of unix:-prefixed host. Goin' fast @ unix-socket fixed.

* Linter

* Proxy properties cleanup. Slight changes of semantics. SERVER_NAME now overrides everything.

* Have server fill in connection info instead of request asking the socket.

- Would be a good idea to remove request.transport entirely but I didn't dare to touch it yet.

* Linter 💣🌟💀

* Fix typing issues. request.server_name returns empty string if host header is missing.

* Fix tests

* Tests were failing, fix connection info.

* Linter nazi says you need that empty line.

* Rename a to addr, leave client empty for unix sockets.

* Add --unix support when sanic is run as module.

* Remove remove_route, deprecated in 19.6.

* Improved unix socket binding.

* More robust creating and unlinking of sockets. Show proper and not temporary name in conn_info.

* Add comprehensive tests for unix socket mode.

* Hide some imports inside functions to avoid Windows failure.

* Mention unix socket mode in deployment docs.

* Fix merge commit.

* Make test_unix_connection_multiple_workers pickleable for spawn mode multiprocessing.

Deprecation and test cleanup (#1818)
* Remove remove_route, deprecated in 19.6.

* No need for py35 compat anymore.

* Rewrite asyncio.coroutines with async/await.

* Remove deprecated request.raw_args.

* response.text() takes str only: avoid deprecation warning in all but one test.

* Remove unused import.

* Revert unnecessary deprecation warning.

* Remove apparently unnecessary py38 compat.

* Avoid asyncio.Task.all_tasks deprecation warning.

* Avoid warning on a test that tests deprecated response.text(int).

* Add pytest-asyncio to tox deps.

* Run the coroutine returned by AsyncioServer.close.

1e4b1c4d1a Forwarded headers and otherwise improved proxy handling (#1638)
* Added support for HTTP Forwarded header and combined parsing of other proxy headers.

- Accessible via request.forwarded that tries parse_forwarded and then parse_xforwarded
- parse_forwarded uses the Forwarded header, if config.FORWARDED_SECRET is provided and a matching header field is found
- parse_xforwarded uses X-Real-IP and X-Forwarded-* much alike the existing implementation
- This commit does not change existing request properties that still use the old code and won't make use of Forwarded headers.

* Use req.forwarded in req properties server_name, server_port, scheme and remote_addr.

X-Scheme handling moved to parse_xforwarded.

* Cleanup and fix req.server_port; no longer reports socket port if any forwards headers are used.

* Update docstrings to incidate that forwarded header is used first.

* Remove testing function.

* Fix tests and linting.

- One test removed due to change of semantics - no socket port will be used if any forwarded headers are in effect.
- Other tests augmented with X-Forwarded-For, to allow the header being tested take effect (shouldn't affect old implementation).

* Try to workaround buggy tools complaining about incorrect ordering of imports.

* Cleanup forwarded processing, add comments. secret is now also returned.

* Added tests, fixed quoted string handling, cleanup.

* Further tests for full coverage.

* Try'n make linter happy.

* Add support for multiple Forwarded headers. Unify parse_forwarded parameters with parse_xforwarded.

* Implement multiple headers support for X-Forwarded-For.

- Previously only the first header was used, so this BUGFIX may affect functionality.

* Bugfix for request.server_name: strip port and other parts.

- request.server_name docs claim that it returns the hostname only (no port).
- config.SERVER_NAME may be full URL, so strip scheme, port and path
- HTTP Host and consequently forwarded Host may include port number, so
  strip that also for forwarded hosts (previously only done for HTTP Host).
- Possible performance benefit of limiting to one split.

* Fallback to app.url_for and let it handle SERVER_NAME if defined (until a proper solution is implemented).

* Revise previous commit. Only fallback for full URL SERVER_NAMEs; allows host to be defined and proxied information still being used.

* Heil lintnazi.

* Modify testcase not to use underscores in URLs. Use hyphens which the spec allows for.

* Forwarded and Host header parsing improved.

- request.forwarded lowercases hosts, separates host:port into their own fields and lowercases addresses
- forwarded.parse_host helper function added and used for parsing all host-style headers (IPv6 cannot be simply split(":")).
- more tests fixed not to use underscores in hosts as those are no longer accepted and lead to the field being rejected

* Fixed typo in docstring.

* Added IPv6 address tests for Host header.

* Fix regex.

* Further tests and stricter forwarded handling.

* Fix merge commit

* Linter

* Linter

* Linter

* Add  to avoid re-using the  variable. Make a few raw strings non-raw.

* Remove unnecessary or

* Updated docs (work in progress).

* Enable REAL_IP_HEADER parsing irregardless of PROXIES_COUNT setting.

- Also cleanup and added comments

* New defaults for PROXIES_COUNT and REAL_IP_HEADER, updated tests.

* Remove support for PROXIES_COUNT=-1.

* Linter errors.

- This is getting ridiculous: cannot fit an URL on one line, linter requires
  splitting the string literal!

* Add support for by=_proxySecret, updated docs, updated tests.

* Forwarded headers' semantics tuning.

- Forwarded host is now preserved in original format
- request.host now returns a forwarded host if available, else the Host header
- Forwarded options are preserved in original order, and later keys override earlier ones
- Forwarded path is automatically URL-unquoted
- Forwarded 'by' and 'for' are omitted if their value is unknown
- Tests modified accordingly
- Cleanup and improved documentation

* Add ASGI test.

* Linter

* Linter #2

2011f3a0b2 PEP 594 has cgi module scheduled for deprecation in Python 3.8 (#1649)
* PEP 594 has cgi module scheduled for deprecation in Python 3.8. Reimplement
cgi.parse_header in Sanic. The new implementation is much faster than either
cgi.parse_header or equivalent werkzeug.parse_options_header, and unlike the
two, handles also quoted values with semicolons or \" in them.

* Fix string escape.

* Useless linter complaints.

* More linter issues

* Add return type hint.

* Do not support quoted-pair escapes.

- Improved documentation and renamed the function more aptly as it only seems
  to apply to content-type and content-disposition headers.

* Unquote filenames also in normal mode.

* Add tests for headers. Adapted from CPython parse_header tests with changes on the final test.

* Linter

* Revert "Unquote filenames also in normal mode."

This reverts commit bf0d502bcd5c443a4178f1c239692976c0f5f185.

* Improved parse_content_header and added tests with Firefox and Chrome.

- Unescaping of quotes moved to parse_content_header because it affects all fields,
  not just filenames.
- It is impossible to handle all cases correctly but the current heuristics should
  suffice well for typical cases and beyond.
- Added comparisons with cgi.parse_header and werkzeug.parse_options_header.

* Updated comments as well.

7c7bedfa5d Fix server crash on request.server_port when bound to IPv6.
If no X-Forwarded-Port nor Host headers are present, Sanic uses "sockname"
to determine the port. This expected (host, port) tuple to be returned but
for IPv6 a 4-tuple is returned instead. Changed code so that port is picked
up in either case. Handling of "peername" was already correct in this regard.

_get_address and server_port both still return incorrect data or crash for
other socket types (e.g unix). Socket type should checked before any queries.
