After reading a question about the `handle_response` feature of `reverse_proxy`, I realized that we didn't have a way of serving an arbitrary file with a status code other than 200. This is an issue in situations where you want to serve a custom error page in routes that are not errors, like the aforementioned `handle_response`, where you may want to retain the status code returned by the proxy but write a response with content from a file.
This feature is super simple, basically if a status code is configured (can be a status code number, or a placeholder string) then that status will be written out before serving the file - if we write the status code first, then the stdlib won't write its own (only the first HTTP status header wins).

(#4050)
* reverseproxy: Implement health_uri, replaces health_path, supports query
Also fixes a bug with `health_status` Caddyfile parsing , it would always only take the first character of the status code even if it didn't end with "xx".
* reverseproxy: Rename to URI, named logger, warn in Provision (for JSON)

This filter is intended to be useful in scenarios where you may want to
redact a value with a static string, giving you information that the
field did previously exist and was present, but not revealing the value
itself in the logs.
This was inspired by work on adding more complete support for removing
sensitive values from logs [1]. An example use case would be the
Authorization header in request log output, for which the value should
usually not be logged, but it may be quite useful for debugging to
confirm that the header was present in the request.

This change is aimed at enhancing the logging module within the
Caddyfile directive to allow users to configure logs other than the HTTP
access log stream, which is the current capability of the Caddyfile [1].
The intent here is to leverage the same syntax as the server log
directive at a global level, so that similar customizations can be added
without needing to resort to a JSON-based configuration.
Discussion for this approach happened in the referenced issue.
Closes https://github.com/caddyserver/caddy/issues/3958

* ci: deflake integration tests by pulling Caddy for the running config until new config is loaded
|
|
Previous commit improved the Caddyfile adapter so it doesn't unnecessarily add names to "skip" in "auto_https" when the server is already HTTP-only.
This commit updates the tests to reflect that change, while also fixing the Caddyfile formatting in many of the tests.
We also print the line number of the divergence between input and formatted version in Caddyfile adapt warnings - very useful for finding initial formatting problems.
|
|
This is probably an invasive change, but existing tests continue to pass.
It seems to make sense this way. There is likely an edge case I haven't
considered.

* reverse_proxy: 1.health check headers can be set through Caddyfile using health_headers directive; 2.health check header host can be set properly
* reverse_proxy:
replace example with syntax definition

* caddyfile: Introduce basic linting and fmt check
This will help encourage people to keep their Caddyfiles tidy.
* Remove unrelated tests
I am not sure that testing the output of warnings here is quite the
right idea; these tests are just for syntax and parsing success.

* implement default values for header directive
closes #3804
* remove `set_default` header op and rely on "require" handler instead
This has the following advantages over the previous attempt:
- It does not introduce a new operation for headers, but rather nicely
extends over an existing feature in the header handler.
- It removes the need to specify the header as "deferred" because it is
already implicitely deferred by the use of the require handler. This
should be less confusing to the user.
* add integration test for header directive in caddyfile
* bubble up errors when parsing caddyfile header directive
* don't export unnecessarily and don't canonicalize headers unnecessarily
* fix response headers not passed in blocks
* caddyfile: fix clash when using default header in block
Each header is now set in a separate handler so that it doesn't clash
with other headers set/added/deleted in the same block.

* httpcaddyfile: Revise automation policy generation
This should fix a frustrating edge case where wildcard subjects are
used, which potentially get shadowed by more specific versions of
themselves; see the new tests for an example. This change is motivated
by an actual customer requirement.
Although all the tests pass, this logic is incredibly complex and
nuanced, and I'm worried it is not correct. But it took me about 4 days
to get this far on a solution. I did my best.
