2020-02-06Remove Starlark, for nowMatthew Holt
This is temporary as we prepare for a stable v2 release. We don't want to make promises we don't know we can keep, and the Starlark integration deserves much more focused attention which resources and funding do not currently permit. When the project is financially stable, I will be able to revisit this properly and add flexible, robust Starlark scripting support to Caddy 2.
2020-02-06caddyfile: tls: Ensure there is always a catch-all conn policy (#3005)Matthew Holt
If user provides their own certs or makes any hostname-specific TLS connection policy, it means that no TLS connection would be served for any other hostnames, even though you'd expect that TLS is enabled for them, too. So now we append a catch-all conn policy if none exist, which allows all ClientHellos to be matched and served. We also fix the consolidation of automation policies, which previously gobbled up automation policies without hosts in favor of automation policies with hosts. Instead of a host-specific policy eating up an identical catch-all policy, the catch-all policy eats up the identical host-specific policy, ensuring that the policy is applied to all hosts which need it.

2020-02-06caddyfile: tls: Tag manual certificates (#2588)Matthew Holt
This ensure that if there are multiple certs that match a particular ServerName or other parameter, then specifically the one the user provided in the Caddyfile will be used.
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.

2020-02-04header: caddyfile: Defer header operations for deletions or manuallyMatthew Holt
See https://caddy.community/t/caddy-server-that-returns-only-ip-address-as-text/6928/6?u=matt In most cases, we will want to apply header operations immediately, rather than waiting until the response is written. The exceptions are generally going to be if we are deleting a header field or if a field is to be overwritten. We now automatically defer header ops if deleting a header field, and allow the user to manually enable deferred mode with the defer subdirective.

2020-01-22rewrite: Prepend "/" if missing from strip path prefixMatthew Holt
Paths always begin with a slash, and omitting the leading slash could be convenient to avoid confusion with a path matcher in the Caddyfile. I do not think there would be any harm to implicitly add the leading slash.

2020-01-19httpcaddyfile: Fix address parsing; don't infer port at parse-timeMatthew Holt
Before, listener ports could be wrong because ParseAddress doesn't know about the user-configured HTTP/HTTPS ports, instead hard-coding port 80 or 443, which could be wrong if the user changed them to something else. Now we defer port and scheme validation/inference to a later part of building the output JSON.

* v2: add documentation for circuit breaker config and "random selection" load balancing policy * v2: rename circuit breaker config inline key from `type` to `breaker` to avoid json key clash between the `circuit_breaker` type and the `type` field of the generic circuit breaker Config struct used by circuit breaking implementations * v2: restore the circuit breaker inline key to `type` and rename the name circuit breaker config field from `Type` to `Factor`
2020-01-17httpcaddyfile: Move redir before rewriteMatthew Holt
Using rewrite is like saying, "I accept this request, but I just need to act on it as if it came in differently." Whereas redir implies more of, "I reject this request, send it to me differently, then I will process it." Makes sense for it to come before rewrites. This can always be changed using the 'order' global option if needed.

2020-01-16httpcaddyfile: Fix nested blocks; add handle directive; refactorMatthew Holt
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.

2020-01-16httpcaddyfile: Replace 'handler_order' option with 'order'Matthew Holt
This allows individual directives to be ordered relative to others, where order matters (for example HTTP handlers). Will primarily be useful when developing new directives, so you don't have to modify the Caddy source code. Can also be useful if you prefer that redir comes before rewrite, for example. Note that these are global options. The route directive can be used to give a specific order to a specific group of HTTP handler directives.
2020-01-16httpcaddyfile: Group try_files routes together (#2891)Matthew Holt
This ensures that only the first matching route is used.
2020-01-15caddyfile: Sort site subroutes by key specificity, and make exclusiveMatthew Holt
In the v1 Caddyfile, only the first matching site definition would be used, so setting these `Terminal: true` ensures that only the first matching one is used in v2, too. We also have to sort by key specificity... Caddy 1 had a special data structure for selecting the most specific site definition, but we don't have that structure in v2, so we need to sort by length (of host and path, separately). For blocks where more than one key is present, we choose the longest host and path (independently, need not be from same key) by which to sort.
2020-01-15rewrite: Make URI modifications more transactional (#2891)Matthew Holt
Before, modifying the path might have affected how a new query string was built if the query string relied on the path. Now, we build each component in isolation and only change the URI on the request later. Also, prevent trailing & in query string.
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.

Sigh... this is what I get for writing code when I'm tired and sick. See https://github.com/caddyserver/caddy/commit/8be1f0ea668492000cdefbd937e0359bdc24bfc1#r36764627
2020-01-11cmd: Assume Caddyfile if name starts with CaddyfileMatthew Holt
And doesn't have .json extension -- in case someone names their JSON config something like Caddyfile.json, which is unconventional.

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.
2020-01-10rewrite: 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.
2020-01-10cmd: Add build-info command; update CertMagicMatthew Holt
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

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.
