2020-01-10rewrite: Rename parameters; implement custom query string parserMatthew Holt
Our new parser also preserves original parameter order, rather than re-encoding using the std lib (which sorts). The renamed parameters are a breaking change but they're new enough that I don't think anyone is using them.

2020-01-09caddyfile: advance cursor for claimed token in NewFromNextTokens() (#2971)Zaq? Wiedmann
When we append a token to the new dispenser, we need to consume it in the parent, too; otherwise it gets scanned twice, which in this case messed up the nesting count which got decremented once too many times.
2020-01-09caddyfile: fix replacing variables on imported files (#2970)Mark Sargent
* fix replacing variables on imported files * refactored replaceEnvVars to ensure it is always called * Use byte slices for easier use Co-authored-by: Matt Holt <mholt@users.noreply.github.com>
2020-01-09caddyfile: Use of vars no longer requires nesting in subroutesMatthew Holt
This is because of our sequential handling logic which was recently merged; if vars is the first handler in the chain, it will be run before the next route's matchers are executed, so there's no need to nest the handlers anymore.
2020-01-09http: Don't use a Host matcher for HTTP->HTTPS redirectsMatthew Holt
In case on-demand TLS is enabled, in that case we don't know the only names that have automatic HTTPS. See https://caddy.community/t/v2-http-to-https-redirects-fail-for-on-demand-ssl-certs/6742?u=matt
2020-01-09Update docs for couple of Caddyfile directivesMatthew Holt
2020-01-09v2: Implement Caddyfile enhancements (breaking changes) (#2960)Matt Holt
* 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.

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.

Config auto-saving is on by default and can be disabled. The --environ flag (or environ subcommand) now print more useful information from Caddy and the runtime, including some nifty paths.

2019-12-29Export Replacer and use concrete type instead of interfaceMatthew Holt
The interface was only making things difficult; a concrete pointer is probably best.
2019-12-28http: Enable TLS for servers listening only on HTTPS portMatthew Holt
It seems silly to have to add a single, empty TLS connection policy to a server to enable TLS when it's only listening on the HTTPS port. We now do this for the user as part of automatic HTTPS (thus, it can be disabled / overridden). See https://caddy.community/t/v2-catch-all-server-with-automatic-tls/6692/2?u=matt
