The comments in the code should explain the new logic thoroughly.
The basic problem for the issue was that we were overriding a catch-all
automation policy's explicitly-configured issuer with our own, for names
that we thought looked like public names. In other words, one could
configure an internal issuer for all names, but then our auto HTTPS
would create a new policy for public-looking names that uses the
default ACME issuer, because we assume public<==>ACME and
nonpublic<==>Internal, but that is not always the case. The new logic
still assumes nonpublic<==>Internal (on catch-all policies only), but
no longer assumes that public-looking names always use an ACME issuer.
Also fix a bug where HTTPPort and HTTPSPort from the HTTP app weren't
being carried through to ACME issuers properly. It required a bit of
refactoring.

Adds `Alt-Svc` to the list of headers that get removed when proxying
to a backend.
This fixes the issue of having the contents of the Alt-Svc header
duplicated when proxying to another Caddy server.

* caddyhttp: Implement CEL matcher (see #3051)
CEL (Common Expression Language) is a very fast, flexible way to express
complex logic, useful for matching requests when the conditions are not
easy to express with JSON.
This matcher may be considered experimental even after the 2.0 release.
* Improve CEL module docs
|
|
* rewrite: strip_prefix, strip_suffix, uri_replace -> uri (closes #3140)
* Add period, to satisfy @whitestrake :) and my own OCD
* Restore implied / prefix
|
|
Also remove Table extension, since GFM (already enabled) apparently
enables strikethrough, table, linkify, and tasklist extensions.

Simply allows the matcher to be specified multiple times in a set
which may be more convenient than one long line.

Holy heck this was complicated

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.

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).

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.

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.

* 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.

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.

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.
|
|
|
|
Now multiple instances of the same matcher can be used within a named
matcher without overwriting previous ones.
|
|
This allows creating links that display only a subset of files in a directory.

* implement regexp var matcher
* use subtests pattern for tests
* be more consistent with naming: MatchVarRE -> MatchVarsRE, var_regexp -> vars_regexp

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.

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.

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.
