* caddyhttp: Support single-line not matcher shortcut
* caddyhttp: Some tests, I guess
|
|

We now store the parsed site/server block keys with the server block,
rather than parsing the addresses every time we read them.
Also detect conflicting schemes, i.e. TLS and non-TLS cannot be served
from the same server (natively -- modules could be built for it).
Also do not add site subroutes (subroutes generated specifically from
site blocks in the Caddyfile) that are empty.

Certificate selection used to be a module, but this seems unnecessary,
especially since the built-in CustomSelectionPolicy allows quite complex
selection logic on a number of fields in certs. If we need to extend
that logic, we can, but I don't think there are SO many possibilities
that we need modules.
This update also allows certificate selection to choose between multiple
matching certs based on client compatibility and makes a number of other
improvements in the default cert selection logic, both here and in the
latest CertMagic.
The hardest part of this was the conn policy consolidation logic
(Caddyfile only, of course). We have to merge connection policies that
we can easily combine, because if two certs are manually loaded in a
Caddyfile site block, that produces two connection policies, and each
cert is tagged with a different tag, meaning only the first would ever
be selected. So given the same matchers, we can merge the two, but this
required improving the Tag selection logic to support multiple tags to
choose from, hence "tags" changed to "any_tag" or "all_tags" (but we
use any_tag in our Caddyfile logic).
Combining conn policies with conflicting settings is impossible, so
that should return an error if two policies with the exact same matchers
have non-empty settings that are not the same (the one exception being
any_tag which we can merge because the logic for them is to OR them).
It was a bit complicated. It seems to work in numerous tests I've
conducted, but we'll see how it pans out in the release candidates.

Now using IANA-compliant names and Go 1.14's CipherSuites() function so
we don't have to maintain our own mapping of currently-secure cipher
suites.

If a site block has a key like "http://localhost:2016", then the log for
that site must be mapped to "localhost:2016" and not just "localhost"
because "localhost:2016" will be the value of the Host header of requests.
But a key like "localhost:80" does not include the port since the Host
header will not include ":80" because it is a standard port.

See https://caddy.community/t/v2-match-any-path-but-files/7326/8?u=matt
If rewrites (or redirects, for that matter) match on file existence,
the file matcher would need to know the root of the site.
Making this change implies that root directives that depend on rewritten
URIs will not work as expected. However, I think this is very uncommon,
and am not sure I have ever seen that. Usually, dynamic roots are based
on host, not paths or query strings.
I suspect that rewrites based on file existence will be more common than
roots based on rewritten URIs, so I am moving root to be the first in
the list.
Users can always override this ordering with the 'order' global option.

This seems unnecessary for now and we can always add it in later if
people have a good reason to need it.

I must have written that one before the helper function
`RegisterHandlerDirective`.

* rewrite: strip_prefix, strip_suffix, uri_replace -> uri (closes #3140)
* Add period, to satisfy @whitestrake :) and my own OCD
* Restore implied / prefix

It's hard to say whether this was actually a bug, but the linked issue
shows why the old behavior was confusing. Basically, we infer that a
rewrite handler is supposed to act as an internal redirect, which likely
means it will no longer match the matcher(s) it did before the rewrite.
So if the rewrite directive shares a matcher with any adjacent route or
directive, it can be confusing/misleading if we consolidate the rewrite
into the same route as the next handler, which shouldn't (probably) match
after the rewrite is complete.
This is kiiiind of a hacky workaround to a quirky problem.
For edge cases like these, it is probably "cleaner" to just use handle
blocks instead, to group handlers under the same matcher, nginx-style.

Holy heck this was complicated
|
|
* added sni tests
* set the default sni when there is no host to match
* removed invalid sni test. Disabled tests that rely on host headers.
* readded SNI tests. Added logging of config load times
|
|
|
|
|
|
* add integration tests
* removed SNI test
* remove integration test condition
* minor edit
* fix sni when using static certificates

* pki: Initial commit of PKI app (WIP) (see #2502 and #3021)
* pki: Ability to use root/intermediates, and sign with root
* pki: Fix benign misnamings left over from copy+paste
* pki: Only install root if not already trusted
* Make HTTPS port the default; all names use auto-HTTPS; bug fixes
* Fix build - what happened to our CI tests??
* Fix go.mod

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

+ a couple other minor changes from linter

* Fix typo
* Fix typo, thanks for Spell Checker under VS Code

* 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)
|

This is useful in 'handle' and 'route' directives, for instance, if you
want to keep your matcher definitions by the directives that use them.

* 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.

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.

Also only append 1 catch-all TLS connection policy to a server, even if
multiple site blocks contribute to that server.

Not sure I love the name of the directive; might change it later.

Forgot to delete this when I moved its test into a different file
|
|
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.

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.
