The fix that was initially put forth in #2971 was good, but only for
up to one layer of nesting. The real problem was that we forgot to
increment nesting when already inside a block if we saw another open
curly brace that opens another block (dispenser.go L157-158).
The new 'handle' directive allows HTTP Caddyfiles to be designed more
like nginx location blocks if the user prefers. Inside a handle block,
directives are still ordered just like they are outside of them, but
handler blocks at a given level of nesting are mutually exclusive.
This work benefitted from some refactoring and cleanup.
* http: path matcher: exact match by default; substring matches (#2959)
This is a breaking change.
* caddyfile: Change "matcher" directive to "@matcher" syntax (#2959)
* cmd: Assume caddyfile adapter for config files named Caddyfile
* Sub-sort handlers by path matcher length (#2959)
Caddyfile-generated subroutes have handlers, which are sorted first by
directive order (this is unchanged), but within directives we now sort
by specificity of path matcher in descending order (longest path first,
assuming that longest path is most specific).
This only applies if there is only one matcher set, and the path
matcher in that set has only one path in it. Path matchers with two or
more paths are not sorted like this; and routes with more than one
matcher set are not sorted like this either, since specificity is
difficult or impossible to infer correctly.
This is a special case, but definitely a very common one, as a lot of
routing decisions are based on paths.
* caddyfile: New 'route' directive for appearance-order handling (#2959)
* caddyfile: Make rewrite directives mutually exclusive (#2959)
This applies only to rewrites in the top-level subroute created by the
HTTP caddyfile.
Adds tests for both the path matcher and host matcher for case
insensitivity.
If case sensitivity is required for the path, a regexp matcher can
be used instead.
This is the v2 equivalent fix of PR #2882.
- Fix static responder so it doesn't replace its own headers config,
and instead replaces the actual response header values
- caddyhttp.ResponseRecorder type optionally buffers response
- Add interface guards to ensure regexp matchers get provisioned
- Use default HTTP port if one is not explicitly set
- Encode middleware writes status code 200 if not written upstream
- Templates and markdown only try to execute on text responses
- Static file server sets Content-Type based on file extension only
(this whole thing -- MIME sniffing, etc -- needs more configurability)
