2020-06-04reverseproxy: Enable changing only the status code (close #2920)Matthew Holt
2020-04-22caddyhttp: Fix trailers when recording responses (fixes #3236)Matthew Holt
2020-04-13core: Don't return error on RegisterModule() and RegisterAdapter()Matthew Holt
These functions are called at init-time, and their inputs are hard-coded so there are no environmental or user factors that could make it fail or succeed; the error return values are often ignored, and when they're not, they are usually a fatal error anyway. To ensure that a programmer mistake is not missed, we now panic instead. Last breaking change 🤞
2020-03-28httpcaddyfile: Put root directive first, before redir and rewriteMatthew Holt
See https://caddy.community/t/v2-match-any-path-but-files/7326/8?u=matt If rewrites (or redirects, for that matter) match on file existence, the file matcher would need to know the root of the site. Making this change implies that root directives that depend on rewritten URIs will not work as expected. However, I think this is very uncommon, and am not sure I have ever seen that. Usually, dynamic roots are based on host, not paths or query strings. I suspect that rewrites based on file existence will be more common than roots based on rewritten URIs, so I am moving root to be the first in the list. Users can always override this ordering with the 'order' global option.
2020-03-15caddyhttp: Clean up; move some code aroundMatthew Holt
2020-03-15caddyhttp: Add support for listener wrapper modulesMatthew Holt
Wrapping listeners is useful for composing custom behavior related to accepting, closing, reading/writing connections (etc) below the application layer; for example, the PROXY protocol.
2020-03-13Some hotfixes for beta 16Matthew Holt
2020-03-13v2: Implement 'pki' app powered by Smallstep for localhost certificates (#3125)Matt Holt
* pki: Initial commit of PKI app (WIP) (see #2502 and #3021) * pki: Ability to use root/intermediates, and sign with root * pki: Fix benign misnamings left over from copy+paste * pki: Only install root if not already trusted * Make HTTPS port the default; all names use auto-HTTPS; bug fixes * Fix build - what happened to our CI tests?? * Fix go.mod
2020-03-06Merge branch 'certmagic-refactor' into v2Matthew Holt
2020-03-06Refactor for CertMagic v0.10; prepare for PKI appMatthew Holt
This is a breaking change primarily in two areas: - Storage paths for certificates have changed - Slight changes to JSON config parameters Huge improvements in this commit, to be detailed more in the release notes. The upcoming PKI app will be powered by Smallstep libraries.

2020-02-25Expose TLS placeholders (#2982)Cameron Moore
* caddytls: Add CipherSuiteName and ProtocolName functions The cipher_suites.go file is derived from a commit to the Go master branch that's slated for Go 1.14. Once Go 1.14 is released, this file can be removed. * caddyhttp: Use commonLogEmptyValue in common_log replacer * caddyhttp: Add TLS placeholders * caddytls: update unsupportedProtocols Don't export unsupportedProtocols and update its godoc to mention that it's used for logging only. * caddyhttp: simplify getRegTLSReplacement signature getRegTLSReplacement should receive a string instead of a pointer. * caddyhttp: Remove http.request.tls.client.cert replacer The previous behavior of printing the raw certificate bytes was ported from Caddy 1, but the usefulness of that approach is suspect. Remove the client cert replacer from v2 until a use case is presented. * caddyhttp: Use tls.CipherSuiteName from Go 1.14 Remove ported version of CipherSuiteName in the process.
2020-02-20caddyhttp: Add handler for unhandled errors in errorChain (#3063)Robin Lambertz
* Add handler for unhandled errors in errorChain Currently, when an error chain is defined, the default error handler is bypassed entirely - even if the error chain doesn't handle every error. This results in pages returning a blank 200 OK page. For instance, it's possible for an error chain to match on the error status code and only handle a certain subtype of errors (like 403s). In this case, we'd want any other errors to still go through the default handler and return an empty page with the status code. This PR changes the "suffix handler" passed to errorChain.Compile to set the status code of the response to the error status code. Fixes #3053 * Move the errorHandlerChain middleware to variable * Style fix
2020-02-18http: Close HTTP/3 servers and listeners; upstream bug irreproducibleMatthew Holt
See https://github.com/lucas-clemente/quic-go/issues/2103 and https://github.com/caddyserver/caddy/pull/2727
2020-02-05http: Split 2-phase auto-HTTPS into 3 phasesMatthew Holt
This is necessary to avoid a race for sockets. Both the HTTP servers and CertMagic solvers will try to bind the HTTP/HTTPS ports, but we need to make sure that our HTTP servers bind first. This is kind of a new thing now that management is async in Caddy 2. Also update to CertMagic 0.9.2, which fixes some async use cases at scale.
2020-02-04caddyhttp: Fix orig_uri placeholder docs (#3002)Francis Lavoie
Fixes #3001
2020-01-13http: Refactor automatic HTTPS (fixes #2972)Matthew Holt
This splits automatic HTTPS into two phases. The first provisions the route matchers and uses them to build the domain set and configure auto HTTP->HTTPS redirects. This happens before the rest of the provisioning does. The second phase takes place at the beginning of the app start. It attaches pointers to the tls app to each server, and begins certificate management for the domains that were found in the first phase.
2020-01-12http: Fix subroutes, ensure that next handlers can still be calledMatthew Holt
2020-01-12http: Fix empty responsesMatthew Holt
Sigh... this is what I get for writing code when I'm tired and sick. See https://github.com/caddyserver/caddy/commit/8be1f0ea668492000cdefbd937e0359bdc24bfc1#r36764627
2020-01-11http: Ensure primary routes always get compiled (fix #2972)Matthew Holt
Including servers for HTTP->HTTPS redirects which do not get provisioned like the rest.
2020-01-10http: Remove {...query_string} placeholder, in favor of {...query}Matthew Holt
I am not sure if the query_string one is necessary or useful yet. We can always add it later if needed.
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
2020-01-09http: 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.

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
2019-12-10v2: Module documentation; refactor LoadModule(); new caddy struct tags (#2924)Matt Holt
This commit goes a long way toward making automated documentation of Caddy config and Caddy modules possible. It's a broad, sweeping change, but mostly internal. It allows us to automatically generate docs for all Caddy modules (including future third-party ones) and make them viewable on a web page; it also doubles as godoc comments. As such, this commit makes significant progress in migrating the docs from our temporary wiki page toward our new website which is still under construction. With this change, all host modules will use ctx.LoadModule() and pass in both the struct pointer and the field name as a string. This allows the reflect package to read the struct tag from that field so that it can get the necessary information like the module namespace and the inline key. This has the nice side-effect of unifying the code and documentation. It also simplifies module loading, and handles several variations on field types for raw module fields (i.e. variations on json.RawMessage, such as arrays and maps). I also renamed ModuleInfo.Name -> ModuleInfo.ID, to make it clear that the ID is the "full name" which includes both the module namespace and the name. This clarity is helpful when describing module hierarchy. As of this change, Caddy modules are no longer an experimental design. I think the architecture is good enough to go forward.

2019-09-30tls: Change struct fields to pointers, add nil checks; rate.Burst updateMatthew Holt
Making them pointers makes for cleaner JSON when adapting configs, if the struct is empty now it will be omitted entirely. The x/time/rate package was updated to support changing the burst, so we've incorporated that here and removed a TODO.
