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.

2020-01-09http: 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.

2019-12-10v2: 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.

2019-10-28v2: Logging! (#2831)Matt Holt
* logging: Initial implementation * logging: More encoder formats, better defaults * logging: Fix repetition bug with FilterEncoder; add more presets * logging: DiscardWriter; delete or no-op logs that discard their output * logging: Add http.handlers.log module; enhance Replacer methods The Replacer interface has new methods to customize how to handle empty or unrecognized placeholders. Closes #2815. * logging: Overhaul HTTP logging, fix bugs, improve filtering, etc. * logging: General cleanup, begin transitioning to using new loggers * Fixes after merge conflict
2019-10-15v2: Make tests work on Windows (#2782)Matt Holt
* file_server: Make tests work on Windows * caddyfile: Fix escaping when character is not escapable We only escape certain characters depending on inside or outside of quotes (mainly newlines and quotes). We don't want everyone to have to escape Windows file paths like C:\\Windows\\... but we can't drop the \ either if it's just C:\Windows\...

2019-09-06Fix Schrodinger's file existence check in file matcherMatthew Holt
See: https://stackoverflow.com/a/12518877/1048862 For example, trying to check the existence of "/www/index.php/index.php" fails but not with an os.IsNotExist()-type error. So we have to assume that a file that cannot be successfully stat'ed at all does not exist.
2019-09-06Various fixes/tweaks to HTTP placeholder variables and file matchingMatthew Holt
- Rename http.var.* -> http.vars.* to be more consistent - Prefixing a path matcher with * now invokes simple suffix matching - Handlers and matchers that need a root path default to {http.vars.root} - Clean replacer output on the file matcher's file selection suffix
2019-08-27Add query_string to HTTP replacer and use it for try_filesMatthew Holt
2019-08-22Fix SIV where /v2 was missing from caddyfile adapter work (#2721)Mohammed Al Sahaf
2019-08-21file_server: Automatically hide all involved CaddyfilesMatthew Holt
2019-08-21Refactor Caddyfile adapter and module registrationMatthew Holt
Use piles from which to draw config values. Module values can return their name, so now we can do two-way mapping from value to name and name to value; whereas before we could only map name to value. This was problematic with the Caddyfile adapter since it receives values and needs to know the name to put in the config.
2019-08-09Fix module-related errorsMatthew Holt
2019-08-09Implement config adapters and beginning of Caddyfile adapterMatthew Holt
Along with several other changes, such as renaming caddyhttp.ServerRoute to caddyhttp.Route, exporting some types that were not exported before, and tweaking the caddytls TLS values to be more consistent. Notably, we also now disable automatic cert management for names which already have a cert (manually) loaded into the cache. These names no longer need to be specified in the "skip_certificates" field of the automatic HTTPS config, because they will be skipped automatically.
2019-08-07Part 1: Optimize using compiler's inliner (#2687)Dominik Braun

2019-07-11Add error & subroute handlers; weakString; other minor handler changesMatthew Holt
2019-07-09Flatten HTTP handler config (#2662)Matthew Holt
Differentiating middleware and responders has one benefit, namely that it's clear which module provides the response, but even then it's not a great advantage. Linear handler config makes a little more sense, giving greater flexibility and simplifying the core a bit, even though it's slightly awkward that handlers which are responders may not use the 'next' handler that is passed in at all.
2019-07-07Fix error handling with Validate when loading modules (fixes #2658)Matthew Holt

2019-06-27Implement etag; fix related bugs in encode and templates middlewaresMatthew Holt
2019-06-21Various bug fixes and minor improvementsMatthew Holt
- Fix static responder so it doesn't replace its own headers config, and instead replaces the actual response header values - caddyhttp.ResponseRecorder type optionally buffers response - Add interface guards to ensure regexp matchers get provisioned - Use default HTTP port if one is not explicitly set - Encode middleware writes status code 200 if not written upstream - Templates and markdown only try to execute on text responses - Static file server sets Content-Type based on file extension only (this whole thing -- MIME sniffing, etc -- needs more configurability)
