* 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
* 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 bf0d502bcd.
* 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.
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.
