2021-06-17fileserver: Only redirect if filename not rewritten (fix #4205)Matthew Holt
This is the more correct implementation of 23dadc0d86dd75dad7559c25f20c9641bc7bc30f (#4179)... I think. This commit effectively undoes the revert in 8848df9c5d372a559d01512b7a4ef00e38867b55, but with corrections to the logic. We *do* need to use the original request path (the path the browser knows) for redirects, since they are external, and rewrites are only internal. However, if the path was rewritten to a non-canonical path, we should not redirect to canonicalize that, since rewrites are intentional by the site owner. Canonicalizing the path involves modifying only the suffix (base element, or filename) of the path. Thus, if a rewrite involves only the prefix (like how handle_path strips a path prefix), then we can (hopefully!) safely redirect using the original URI since the filename was not rewritten. So basically, if rewrites modify the filename, we should not canonicalize those requests. If rewrites only modify another part of the path (commonly a prefix), we should be OK to redirect.
2021-06-16fileserver: Don't persist parsed template (fix #4202)Matthew Holt
Templates are parsed at request-time (like they are in the templates middleware) to allow live changes to the template while the server is running. Fixes race condition. Also refactored use of a buffer so a buffer put back in the pool will not continue to be used (written to client) in the meantime. A couple of benchmarks removed due to refactor, which is fine, since we know pooling helps here.
2021-06-14Revert "fileserver: Redirect within the original URL (#4179)"Matthew Holt
This reverts commit f9b54454a19e2b070159ce8d2af76d819658244e. /cc @diamondburned (see #4205)
2021-06-07fileserver: Fix browse not redirecting query parameters (#4196)diamondburned
This commit is a follow up to PR #4179 that introduced a bug where browse redirections to the right URL would not preserve query parameters.
2021-06-07fileserver: Redirect within the original URL (#4179)diamondburned
This commit changes the file_server directive to redirect using the original request's URL instead of the possibly trimmed URL. This should make file_server work with handle_path. This fix is taken from mholt's comment in https://caddy.community/t/file-servers-on-different-paths-not-working/11698/11.
2021-05-04fileserver: Fix `file` matcher with empty `try_files` (#4147)Francis Lavoie
* fileserver: Fix `file` matcher with empty `try_files` Fixes https://github.com/caddyserver/caddy/issues/4146 If `TryFiles` is empty, we fill it with `r.URL.Path`. In this case, this is `/`. Then later, in `prepareFilePath()`, we run the replacer (which turns `{path}` into `/` at that point) but `file` remains the original value (and the placeholder is still the placeholder there). So then `strings.HasSuffix(file, "/")` will be `false` for the placeholder, but `true` for the empty `TryFiles` codepath, because `file` was `/` due to being set to the actual request value beforehand. This means that `suffix` becomes `//` in that case, so after `sanitizedPathJoin`, it becomes `./`, so `strictFileExists`'s `strings.HasSuffix(file, separator)` codepath will return true. I think we should change the `m.TryFiles == nil` codepath to `m.TryFiles = []string{"{http.request.uri.path}"}` for consistency. (And maybe consider hoisting this to `Provision` cause there's no point doing this on every request). I don't think this "optimization" of directly using `r.URL.Path` is so valuable, cause it causes this edgecase with directories. * Update modules/caddyhttp/fileserver/matcher.go Co-authored-by: Matt Holt <mholt@users.noreply.github.com> Co-authored-by: Matt Holt <mholt@users.noreply.github.com>

2021-04-29fileserver: Better handling of HTTP status override (#4132)Francis Lavoie
2021-04-08fileserver: Add status code override (#4076)Francis Lavoie
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).

2020-09-11fileserver: Improve file hiding logic for directories and prefixesMatthew Holt
Now, a filename to hide that is specified without a path separator will count as hidden if it appears in any component of the file path (not only the last component); semantically, this means hiding a file by only its name (without any part of a path) will hide both files and folders, e.g. hiding ".git" will hide "/.git" and also "/.git/foo". We also do prefix matching so that hiding "/.git" will hide "/.git" and "/.git/foo" but not "/.gitignore". The remaining logic is a globular match like before.

2020-01-09http: Change routes to sequential matcher evaluation (#2967)Matt Holt
Previously, all matchers in a route would be evaluated before any handlers were executed, and a composite route of the matching routes would be created. This made rewrites especially tricky, since the only way to defer later matchers' evaluation was to wrap them in a subroute, or to invoke a "rehandle" which often caused bugs. Instead, this new sequential design evaluates each route's matchers then its handlers in lock-step; matcher-handlers-matcher-handlers... If the first matching route consists of a rewrite, then the second route will be evaluated against the rewritten request, rather than the original one, and so on. This should do away with any need for rehandling. I've also taken this opportunity to avoid adding new values to the request context in the handler chain, as this creates a copy of the Request struct, which may possibly lead to bugs like it has in the past (see PR #1542, PR #1481, and maybe issue #2463). We now add all the expected context values in the top-level handler at the server, then any new values can be added to the variable table via the VarsCtxKey context key, or just the GetVar/SetVar functions. In particular, we are using this facility to convey dial information in the reverse proxy. Had to be careful in one place as the middleware compilation logic has changed, and moved a bit. We no longer compile a middleware chain per- request; instead, we can compile it at provision-time, and defer only the evaluation of matchers to request-time, which should slightly improve performance. Doing this, however, we take advantage of multiple function closures, and we also changed the use of HandlerFunc (function pointer) to Handler (interface)... this led to a situation where, if we aren't careful, allows one request routed a certain way to permanently change the "next" handler for all/most other requests! We avoid this by making a copy of the interface value (which is a lightweight pointer copy) and using exclusively that within our wrapped handlers. This way, the original stack frame is preserved in a "read-only" fashion. The comments in the code describe this phenomenon. This may very well be a breaking change for some configurations, however I do not expect it to impact many people. I will make it clear in the release notes that this change has occurred.
