* More informative rewrite test output
When running rewrite tests, the output in case of a test failure now
includes not only the rewritten URLs but also the from URL.
* Move re-escaping to regexpMatches
This commit moves the code to post-process the match replacements from
ComplexRule to regexpMatches, so it can later be re-used for SimpleRule.
Also changes the comment in an attempt to better explain the reasoning
behind that code.
The required strings.Replacer is now built only once.
* Support regex captures in simple rewrite rules
Closes#2586
* httpserver/all: Clean up and standardize request URL handling
The HTTP server now always creates a context value on the request which
is a copy of the request's URL struct. It should not be modified by
middlewares, but it is safe to get the value out of the request and make
changes to it locally-scoped. Thus, the value in the context always
stores the original request URL information as it was received. Any
rewrites that happen will be to the request's URL field directly.
The HTTP server no longer cleans /sanitizes the request URL. It made too
many strong assumptions and ended up making a lot of middleware more
complicated, including upstream proxying (and fastcgi). To alleviate
this complexity, we no longer change the request URL. Middlewares are
responsible to access the disk safely by using http.Dir or, if not
actually opening files, they can use httpserver.SafePath().
I'm hoping this will address issues with #1624, #1584, #1582, and others.
