It's still not perfect but I think it should be more correct for
slightly more complex configs. Might still fall apart for complex
configs that use on-demand TLS or at a large scale (workarounds are
to just implement your own redirects, very easy to do anyway).
Fixes#3116
* Rework Replacer loop to ignore escaped braces
* Add benchmark tests for replacer
* Optimise handling of escaped braces
* Handle escaped closing braces
* Remove additional check for closing brace
This commit removes the additional check for input in which the closing
brace appears before the opening brace. This check has been removed for
performance reasons as it is deemed an unlikely edge case.
* Check for escaped closing braces in placeholder name
* ability to specify that client cert must be present in SSL
* changed the clientauthtype to string and make room for the values supported by go as in caddy1
* renamed the config parameter according to review comments and added documentation on allowed values
* missed a reference
* Minor cleanup; docs enhancements

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.
* remove the certificate tag tracking from global state
* refactored helper state, added log counter
* moved state initialisation close to where it is used.
* added helper state comment
Previously the formatter did not include support for
blocks inside other blocks. Hence the formatter could
not indent some files properly. This fixes it.
Fixes#3104

This takes the config file as input and formats it.
Prints the result to stdout. Can write changes to
file if `--write` flag is passed.

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).
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
* 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)
* 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.
* 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
* 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
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.
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.
