2020-02-27reverse_proxy: Allow use of URL to specify schemeMatthew Holt
This makes it more convenient to configure quick proxies that use HTTPS but also introduces a lot of logical complexity. We have to do a lot of verification for consistency and errors. Path and query string is not supported (i.e. no rewriting). Scheme and port can be inferred from each other if HTTP(S)/80/443. If omitted, defaults to HTTP. Any explicit transport config must be consistent with the upstream schemes, and the upstream schemes must all match too. But, this change allows a config that used to require this: reverse_proxy example.com:443 { transport http { tls } } to be reduced to this: reverse_proxy https://example.com which is really nice syntactic sugar (and is reminiscent of Caddy 1).

"Transparent mode" is the default, just like the actual handler.

2020-02-26caddyfile: expand environment variables within caddy files (#3082)Zaq? Wiedmann
Small expansion to the work done in https://github.com/caddyserver/caddy/pull/2963 which simply calls `os.ExpandEnv` so env vars like `{$URL}` where `$URL=$SCHEME://$HOST:$PORT` (contrived) get the expanded $SCHEME, $HOST, and $PORT variables included
2020-02-26Initial implementation of global default SNI option (#3047)Mark Sargent
* add global default sni * fixed grammar * httpcaddyfile: Reduce some duplicated code * Um, re-commit already-committed commit, I guess? (sigh) Co-authored-by: Matt Holt <mholt@users.noreply.github.com>
2020-02-25v2: 'log' directive for Caddyfile, and debug mode (#3052)Matt Holt
* httpcaddyfile: Begin implementing log directive, and debug mode For now, debug mode just sets the log level for all logs to DEBUG (unless a level is specified explicitly). * httpcaddyfile: Finish 'log' directive Also rename StringEncoder -> SingleFieldEncoder * Fix minor bug in replacer (when vals are empty)
2020-02-25httpcaddyfile: Matchers can now be embedded into a nested scopeMatthew Holt
This is useful in 'handle' and 'route' directives, for instance, if you want to keep your matcher definitions by the directives that use them.
2020-02-25go.mod: Bump to Go 1.14Matthew Holt
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.

2020-02-23reverse_proxy: Health checks: Don't cross the streamsMatthew Holt

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
2020-02-20caddyhttp: Fixes for header and header_regexp directives (#3061)Gilbert Gilb's
* Fix crash when specifying "*" to header directive. Fixes #3060 * Look Host header in header and header_regexp. Also, if more than one header is provided, header_regexp now looks for extra headers values to reflect the behavior from header. Fixes #3059 * Fix parsing of named header_regexp in Caddyfile. See #3059
2020-02-20httpcaddyfile: tls: Load repeated cert files only once, with one tagMatthew Holt
See end of issue #3004. Loading the same certificate file multiple times with different tags will result in it being de-duplicated in the in- memory cache, because of course they all have the same bytes. This meant that any certs of the same filename loaded with different tags would be overwritten by the next certificate of the same filename, and any conn policies looking for the tags of the previous ones would never find them, causing connections to fail. So, now we remember cert filenames and their tags, instead of loading them multiple times and overwriting previous ones. A user crafting their own JSON might make this error too... maybe we won't see it happen. But if it does, one possibility is, when loading a duplicate cert, instead of discarding it completely, merge the tag list into the one that's already stored in the cache, then discard.
2020-02-20httpcaddyfile: Combine repeated cert loaders (fix #3004)Matthew Holt
Also only append 1 catch-all TLS connection policy to a server, even if multiple site blocks contribute to that server.
2020-02-18httpcaddyfile: Properly add all cert loaders across sites (fixes #3056)Matthew Holt
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
2020-02-18tls: Fix panic loading automation management modules (fix #3004)Matthew Holt
When AutomationPolicy was turned into a pointer, we continued passing a double pointer to LoadModule, oops.
2020-02-17basicauth: default hash to bcrypt (#3050)Robin Lambertz
The documentation specifies that the hash algorithm defaults to bcrypt. However, the implementation returns an error in provision if no hash is provided. Fix this inconsistency by *actually* defaulting to bcrypt.
2020-02-17go.mod: update quic-go to v0.14.4 (#3048)Marten Seemann
2020-02-16httpcaddyfile: 'handle_errors' directiveMatthew Holt
Not sure I love the name of the directive; might change it later.
2020-02-16httpcaddyfile: Refactor global options parsing; prevent duplicate keysMatthew Holt
2020-02-16http: Remove redundant test fileMatthew Holt
Forgot to delete this when I moved its test into a different file
2020-02-14tls: Avoid duplication AutomationPolicies for large quantities of namesMatthew Holt
This should greatly reduce memory usage at scale. Part of an overall effort between Caddy 2 and CertMagic to optimize for large numbers of names.
2020-02-14Minor tweaks to docs/commentsMatthew Holt
2020-02-14caddyfile: Refactor; NewFromNextSegment(); fix repeated matchersMatthew Holt
Now multiple instances of the same matcher can be used within a named matcher without overwriting previous ones.
2020-02-12tls: Add acme_ca_root and tls/ca_root to caddyfile (#3040)Mark Sargent
2020-02-08httpcaddyfile: Add support for DNS challenge solversMatthew Holt
Configuration via the Caddyfile requires use of env variables, but an upstream issue is currently blocking that: https://github.com/go-acme/lego/issues/1054 Providers will need to be retrofitted upstream in order to support env var configuration.
2020-02-08browse: allow filter init via `filter` query param (#3027)Jeremy Lin
This allows creating links that display only a subset of files in a directory.
2020-02-08v2: Implement RegExp Vars Matcher (#2997)Mohammed Al Sahaf
* implement regexp var matcher * use subtests pattern for tests * be more consistent with naming: MatchVarRE -> MatchVarsRE, var_regexp -> vars_regexp
2020-02-07tls: Slight adjustment to how DNS provider modules are loadedMatthew Holt
We don't load the provider directly, because the lego provider types aren't designed for JSON configuration and they are not implemented as Caddy modules (there are some setup steps which a Provision call would need to do, but they do not have Provision methods, they have their own constructor functions that we have to wrap). Instead of loading the challenge providers directly, the modules are simple wrappers over the challenge providers, to facilitate the JSON config structure and to provide a consistent experience. This also lets us swap out the underlying challenge providers transparently if needed; it acts as a layer of abstraction.
2020-02-07Fix typo in readmeMatthew Holt
2020-02-07Update readmeMatthew Holt
The list of improvements and FAQ were moved to the wiki for now. They still need to be updated.
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. See also: https://caddy.community/t/v2-automatic-https-certificate-errors/6847/9?u=matt
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.
2020-02-04caddyhttp: Fix orig_uri placeholder docs (#3002)Francis Lavoie

2020-02-04httpcaddyfile: Make root directive mutually exclusiveMatthew Holt
See https://caddy.community/t/caddyfile-and-v2/6766/22?u=matt
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.
