* httpcaddyfile: Add `{vars.*}` placeholder shortcut
I'm yoinking this from my https://github.com/caddyserver/caddy/pull/4657 PR because I think we should get this in ASAP for v2.5.0 along with the new `vars` directive.
* Sort vars by matchers in reverse
Includes several breaking changes; code base updated accordingly.
- Added lots of context arguments
- Use fs.ErrNotExist
- Rename ACMEManager -> ACMEIssuer; CertificateManager -> Manager
Guh, this is complicated.
Fixes#4640
This also follows up on #4398 (reverting it) which made a change that technically worked, but was incorrect. It changed the condition in `hostsFromKeysNotHTTP` from `&&` to `||`, but then the function no longer did what its name said it would do, and it would return hosts even if they were marked with `http://`, if they used a non-HTTP port. That wasn't the intent of it. The test added in there was kept though, because it is a valid usecase.
The actual fix is to check _earlier_ whether all the addresses explicitly have `http://`, and if so we can short circuit and skip considering the rest.

* reverseproxy: New `copy_response` handler for `handle_response` routes
Followup to #4298 and #4388.
This adds a new `copy_response` handler which may only be used in `reverse_proxy`'s `handle_response` routes, which can be used to actually copy the proxy response downstream.
Previously, if `handle_response` was used (with routes, not the status code mode), it was impossible to use the upstream's response body at all, because we would always close the body, expecting the routes to write a new body from scratch.
To implement this, I had to refactor `h.reverseProxy()` to move all the code that came after the `HandleResponse` loop into a new function. This new function `h.finalizeResponse()` takes care of preparing the response by removing extra headers, dealing with trailers, then copying the headers and body downstream.
Since basically what we want `copy_response` to do is invoke `h.finalizeResponse()` at a configurable point in time, we need to pass down the proxy handler, the response, and some other state via a new `req.WithContext(ctx)`. Wrapping a new context is pretty much the only way we have to jump a few layers in the HTTP middleware chain and let a handler pick up this information. Feels a bit dirty, but it works.
Also fixed a bug with the `http.reverse_proxy.upstream.duration` placeholder, it always had the same duration as `http.reverse_proxy.upstream.latency`, but the former was meant to be the time taken for the roundtrip _plus_ copying/writing the response.
* Delete the "Content-Length" header if we aren't copying
Fixes a bug where the Content-Length will mismatch the actual bytes written if we skipped copying the response, so we get a message like this when using curl:
```
curl: (18) transfer closed with 18 bytes remaining to read
```
To replicate:
```
{
admin off
debug
}
:8881 {
reverse_proxy 127.0.0.1:8882 {
@200 status 200
handle_response @200 {
header Foo bar
}
}
}
:8882 {
header Content-Type application/json
respond `{"hello": "world"}` 200
}
```

* Add a override_domain option to allow DNS chanllenge delegation
CNAME can be used to delegate answering the chanllenge to another DNS
zone. One usage is to reduce the exposure of the DNS credential [1].
Based on the discussion in caddy/certmagic#160, we are adding an option
to allow the user explicitly specify the domain to delegate, instead of
following the CNAME chain.
This needs caddy/certmagic#160.

The `net.JoinHostPort()` function has some naiive logic for handling IPv6, it just checks if the host part has a `:` and if so it wraps the host part with `[ ]` but this causes our network type prefix to get wrapped as well, which is invalid for `caddy.NetworkAddress`. Instead, we can just concatenate the host and port manually here to avoid this side-effect.
We realized we made some mistakes with the directive ordering, so we're making some minor adjustments.
`abort` and `error` don't really make sense to be after other handler directives, because you would expect to be able to "fail-fast" and throw an error before falling through to some `file_server` or `respond` typically. So we're moving them up to just before `respond`, i.e. before the common handler directives.
This is also more consistent with our existing examples in the docs, which actually didn't work due to the directive ordering. See https://caddyserver.com/docs/caddyfile/directives/error#examples
Also, `push` doesn't quite make sense to be after `handle`/`route`, since its job is to read from response headers to push additional resources if necessary, and `handle`/`route` may be terminal so push would not be reached if it was declared outside those. And also, it would make sense to be _before_ `templates` because a template _could_ add a `Link` header to the response dynamically.
Some new users mistakenly try to define two sites without braces around each. Doing this can yield a confusing error message saying that their site address is an "unknown directive".
We can do better by keeping track of whether the current site block was parsed with or without a brace, then changing the error message later based on that.
For example, now this invalid config:
```
foo.example.com
respond "foo"
bar.example.com
respond "bar"
```
Will yield this error message:
```
$ caddy adapt
2021/08/22 19:21:31.028 INFO using adjacent Caddyfile
adapt: Caddyfile:4: unrecognized directive: bar.example.com
Did you mean to define a second site? If so, you must use curly braces around each site to separate their configurations.
```
Some users forget to use a comma between their site addresses. This is invalid (commas aren't a valid character in domains) and later parts of the code like certificate automation will try to use this otherwise, which doesn't make sense. Best to error as early as possible.
Example thread on the forums where this happened: https://caddy.community/t/simplify-caddyfile/13281/9
* httpcaddyfile: Add shortcut for proxy hostport placeholder
I've noticed that it's a pretty common pattern to write a proxy like this, when needing to proxy over HTTPS:
```
reverse_proxy https://example.com {
header_up Host {http.reverse_proxy.upstream.hostport}
}
```
I find it pretty hard to remember the exact placeholder to use for this, and I continually need to refer to the docs when I need it. I think a simple fix for this is to add another Caddyfile placeholder for this one to shorten it:
```
reverse_proxy https://example.com {
header_up Host {proxy_hostport}
}
```
* Switch the shortcut name
* httpcaddyfile: ensure hosts to skip can always be collected
Previously, some hosts that should be skipped in logging would
be missed as the current logic would only collect them after
encountering the first server that would log. This change makes sure
the ServerLogConfig is initialized before iterating over the server
blocks.
* httpcaddyfile: add test case for skip hosts behavior
If an email is specified in global options, a site called 'localhost' shouldn't be bunched together with public DNS names in the automation policies, which get the default, public-CA issuers. Fix old test that did this.
I also noticed that these two:
localhost {
}
example.com {
}
and
localhost, example.com {
}
produce slightly different TLS automation policies. The former is what the new test case covers, and we have logic that removes the empty automation policy for localhost so that auto-HTTPS can implicitly create one. (We prefer that whenever possible.) But the latter case produces two automation policies, with the second one being for localhost, with an explicit internal issuer. It's not wrong, just more explicit than it needs to be.
I'd really like to completely rewrite the code from scratch that generates automation policies, hopefully there is a simpler, more correct algorithm.
In the Caddyfile, hosts specified for HTTP sockets (either scheme is "http" or it is on the HTTP port) should not be used as subjects in TLS automation policies (APs).
* caddyfile: Add parse error on site address in `{`
This is an incredibly common mistake made by users, so we should catch it earlier in the parser and give a more friendly message. Often it ends up adapting but with mistakes, or erroring out later due to other site addresses being read as directives.
There's not really ever a situation where a lone '{' is valid at the end of a site address (but I suppose there are edgecases where the user wants to use a path matcher where it ends specifically in `{`, but... why?), so this should be fine.
* Update caddyconfig/caddyfile/parse.go
* caddyfile(formatter): fix nesting not decrementing
This is an extremely weird edge-case where if you had a environment variable {}
on one line, a comment on the next line, and the closing of the block on the
following line; the rest of the Caddyfile would be indented further than it
should've been.

* caddyfile: Fix `import` replacing unrelated placeholders
See https://caddy.community/t/snippet-issue-works-outside-snippet/12231
So it turns out that `NewReplacer()` gives a replacer with some global defaults (like `{env.*}` and some system and time placeholders), which is not ideal when running `import` because we just want to replace `{args.*}` only, and nothing else.

* address review comments
This change is aimed at enhancing the logging module within the
Caddyfile directive to allow users to configure logs other than the HTTP
access log stream, which is the current capability of the Caddyfile [1].
The intent here is to leverage the same syntax as the server log
directive at a global level, so that similar customizations can be added
without needing to resort to a JSON-based configuration.
Discussion for this approach happened in the referenced issue.
Closes https://github.com/caddyserver/caddy/issues/3958
[1] https://caddyserver.com/docs/caddyfile/directives/log
Allows conveniently setting the resolvers for the DNS challenge using a TLS subdirective, which applies to default issuers, rather than having to explicitly define the issuers and overwrite the defaults.
The HTTP Caddyfile adapter can now configure the PKI app, and the acme_server directive can now be used to specify a custom CA used for issuing certificates. More customization options can follow later as needed.
If `tls <email>` is used, we should apply that to all applicable default issuers, not drop them. This refactoring applies implicit ACME issuer settings from the tls directive to all default ACME issuers, like ZeroSSL.
We also consolidate some annoying logic and improve config validity checks.

* caddyhttp: Implement handler abort; new 'abort' directive (close#3871)
* Move abort directive ordering; clean up redirects
Seems logical for the end-all of handlers to go at the... end.
The Connection header no longer needs to be set there, since Close is
true, and the static_response handler now does that.
This commits dds 3 separate, but very related features:
1. Automated server identity management
How do you know you're connecting to the server you think you are? How do you know the server connecting to you is the server instance you think it is? Mutually-authenticated TLS (mTLS) answers both of these questions. Using TLS to authenticate requires a public/private key pair (and the peer must trust the certificate you present to it).
Fortunately, Caddy is really good at managing certificates by now. We tap into that power to make it possible for Caddy to obtain and renew its own identity credentials, or in other words, a certificate that can be used for both server verification when clients connect to it, and client verification when it connects to other servers. Its associated private key is essentially its identity, and TLS takes care of possession proofs.
This configuration is simply a list of identifiers and an optional list of custom certificate issuers. Identifiers are things like IP addresses or DNS names that can be used to access the Caddy instance. The default issuers are ZeroSSL and Let's Encrypt, but these are public CAs, so they won't issue certs for private identifiers. Caddy will simply manage credentials for these, which other parts of Caddy can use, for example: remote administration or dynamic config loading (described below).
2. Remote administration over secure connection
This feature adds generic remote admin functionality that is safe to expose on a public interface.
- The "remote" (or "secure") endpoint is optional. It does not affect the standard/local/plaintext endpoint.
- It's the same as the [API endpoint on localhost:2019](https://caddyserver.com/docs/api), but over TLS.
- TLS cannot be disabled on this endpoint.
- TLS mutual auth is required, and cannot be disabled.
- The server's certificate _must_ be obtained and renewed via automated means, such as ACME. It cannot be manually loaded.
- The TLS server takes care of verifying the client.
- The admin handler takes care of application-layer permissions (methods and paths that each client is allowed to use).\
- Sensible defaults are still WIP.
- Config fields subject to change/renaming.
3. Dyanmic config loading at startup
Since this feature was planned in tandem with remote admin, and depends on its changes, I am combining them into one PR.
Dynamic config loading is where you tell Caddy how to load its config, and then it loads and runs that. First, it will load the config you give it (and persist that so it can be optionally resumed later). Then, it will try pulling its _actual_ config using the module you've specified (dynamically loaded configs are _not_ persisted to storage, since resuming them doesn't make sense).
This PR comes with a standard config loader module called `caddy.config_loaders.http`.
Caddyfile config for all of this can probably be added later.
COMMITS:
* admin: Secure socket for remote management
Functional, but still WIP.
Optional secure socket for the admin endpoint is designed
for remote management, i.e. to be exposed on a public
port. It enforces TLS mutual authentication which cannot
be disabled. The default port for this is :2021. The server
certificate cannot be specified manually, it MUST be
obtained from a certificate issuer (i.e. ACME).
More polish and sensible defaults are still in development.
Also cleaned up and consolidated the code related to
quitting the process.
* Happy lint
* Implement dynamic config loading; HTTP config loader module
This allows Caddy to load a dynamic config when it starts.
Dynamically-loaded configs are intentionally not persisted to storage.
Includes an implementation of the standard config loader, HTTPLoader.
Can be used to download configs over HTTP(S).
* Refactor and cleanup; prevent recursive config pulls
Identity management is now separated from remote administration.
There is no need to enable remote administration if all you want is identity
management, but you will need to configure identity management
if you want remote administration.
* Fix lint warnings
* Rename identities->identifiers for consistency
Previous commit improved the Caddyfile adapter so it doesn't unnecessarily add names to "skip" in "auto_https" when the server is already HTTP-only.
This commit updates the tests to reflect that change, while also fixing the Caddyfile formatting in many of the tests.
We also print the line number of the divergence between input and formatted version in Caddyfile adapt warnings - very useful for finding initial formatting problems.
This is probably an invasive change, but existing tests continue to pass.
It seems to make sense this way. There is likely an edge case I haven't
considered.
Allows user to disable OCSP stapling (including support in the Caddyfile via the ocsp_stapling global option) or overriding responder URLs. Useful in environments where responders are not reachable due to firewalls.
This changes the signature of UnmarshalGlobalFunc but this is probably OK since it's only used by this repo as far as we know.
We need this change in order to "remember" the previous value in case a global option appears more than once, which is now a possibility with the cert_issuer option since Caddy now supports multiple issuers in the order defined by the user.
Bonus: the issuer subdirective of tls now supports one-liner for "acme" when all you need to set is the directory:
issuer acme <dir>

* implement default values for header directive
closes#3804
* remove `set_default` header op and rely on "require" handler instead
This has the following advantages over the previous attempt:
- It does not introduce a new operation for headers, but rather nicely
extends over an existing feature in the header handler.
- It removes the need to specify the header as "deferred" because it is
already implicitely deferred by the use of the require handler. This
should be less confusing to the user.
* add integration test for header directive in caddyfile
* bubble up errors when parsing caddyfile header directive
* don't export unnecessarily and don't canonicalize headers unnecessarily
* fix response headers not passed in blocks

Each header is now set in a separate handler so that it doesn't clash
with other headers set/added/deleted in the same block.

* httpcaddyfile: Revise automation policy generation
This should fix a frustrating edge case where wildcard subjects are
used, which potentially get shadowed by more specific versions of
themselves; see the new tests for an example. This change is motivated
by an actual customer requirement.
Although all the tests pass, this logic is incredibly complex and
nuanced, and I'm worried it is not correct. But it took me about 4 days
to get this far on a solution. I did my best.
* Fix typo
We have users that have site blocks like *.*.tld with on-demand TLS
enabled. While *.*.tld does not qualify for a publicly-trusted cert due
to its wildcards, On-Demand TLS does not actually obtain a cert with
those wildcards, since it uses the actual hostname on the handshake.
This improves on that logic, but I am still not 100% satisfied with the
result since I think we need to also check if another site block is more
specific, like foo.example.tld, which might not have on-demand TLS
enabled, and make sure an automation policy gets created before the
more general policy with on-demand...

false, the policy wouldn't actually be added, even if
hasCatchAllTLSConnPolicy was set to true on the previous line.
Now we set that variable in accordance with whether we actually add
the policy.
While debugging this I noticed that catch-all policies added early in
that loop (i.e. not at the end if we later determine we need one) are
not always at the end of the list. They should be, though, since they
are selected by which one matches first, and having a catch-all first
would nullify any more specific ones later in the list. So I added a
sort in consolidateConnPolicies to take care of that.
Should fix#3670 and

but I won't know for sure until somebody verifies it, since at least in
the GitHub issue there is not yet enough information (the configs are
redacted).

* caddytls: Add support for ZeroSSL; add Caddyfile support for issuers
Configuring issuers explicitly in a Caddyfile is not easily compatible
with existing ACME-specific parameters such as email or acme_ca which
infer the kind of issuer it creates (this is complicated now because
the ZeroSSL issuer wraps the ACME issuer)... oh well, we can revisit
that later if we need to.
New Caddyfile global option:
{
cert_issuer <name> ...
}
Or, alternatively, as a tls subdirective:
tls {
issuer <name> ...
}
For example, to use ZeroSSL with an API key:
{
cert_issuser zerossl API_KEY
}
For now, that still uses ZeroSSL's ACME endpoint; it fetches EAB
credentials for you. You can also provide the EAB credentials directly
just like any other ACME endpoint:
{
cert_issuer acme {
eab KEY_ID MAC_KEY
}
}
All these examples use the new global option (or tls subdirective). You
can still use traditional/existing options with ZeroSSL, since it's
just another ACME endpoint:
{
acme_ca https://acme.zerossl.com/v2/DV90
acme_eab KEY_ID MAC_KEY
}
That's all there is to it. You just can't mix-and-match acme_* options
with cert_issuer, because it becomes confusing/ambiguous/complicated to
merge the settings.

Catch-alls should always go last. Normally this is the case, but we have

This removes an optimization where we amortized path matcher decoding.
The decoded matchers were index by... position... which obviously
changes during sorting. Duh.
Anyway, sorting is sliiightly slower now but the Caddyfile is not
really CPU-sensitive, so this is fine.
This can lead to nicer, smaller JSON output for Caddyfiles like this:
a {
tls internal
}
b {
tls foo@bar.com
}
i.e. where the tls directive only configures automation policies, and
is merely meant to enable TLS on a server block (if it wasn't implied).
This helps keeps implicit config implicit.
Needs a little more testing to ensure it doesn't break anything
important.
* httpcaddyfile: Exclude access logs written to files from default log
Even though any logs can just be ignored, most users don't seem to like
configuring an access log to go to a file only to have it doubly appear
in the default log.

Panic would happen if an automation policy was specified in a singular
server block that had no hostnames in its address. Definitely an edge
case.
Fixed a bug related to checking for server blocks with a host-less key
that tried to make an automation policy. Previously if you had only two
server blocks like ":443" and another one at ":80", the one at ":443"
could not create a TLS automation policy because it thought it would
interfere with TLS automation for the block at ":80", but obviously that
key doesn't enable TLS because it is on the HTTP port. So now we are a
little smarter and count only non-HTTP-empty-hostname keys.
Also fixed a bug so that a key like "https://:1234" is sure to have TLS
enabled by giving it a TLS connection policy. (Relaxed conditions
slightly; the previous conditions were too strict, requiring there to be
a TLS conn policy already or a default SNI to be non-empty.)
Also clarified a comment thanks to feedback from @Mohammed90
These functions are called at init-time, and their inputs are hard-coded
so there are no environmental or user factors that could make it fail
or succeed; the error return values are often ignored, and when they're
not, they are usually a fatal error anyway. To ensure that a programmer
mistake is not missed, we now panic instead.
Last breaking change 🤞
- Create two default automation policies; if the TLS app is used in
isolation with the 'automate' certificate loader, it will now use
an internal issuer for internal-only names, and an ACME issuer for
all other names by default.
- If the HTTP Caddyfile adds an 'automate' loader, it now also adds an
automation policy for any names in that loader that do not qualify
for public certificates so that they will be issued internally. (It
might be nice if this wasn't necessary, but the alternative is to
either make auto-HTTPS logic way more complex by scanning the names in
the 'automate' loader, or to have an automation policy without an
issuer switch between default issuer based on the name being issued
a certificate - I think I like the latter option better, right now we
do something kind of like that but at a level above each individual
automation policies, we do that switch only when no automation
policies match, rather than when a policy without an issuer does
match.)
- Set the default LoggerName rather than a LoggerNames with an empty
host value, which is now taken literally rather than as a catch-all.
- hostsFromKeys, the function that gets a list of hosts from server
block keys, no longer returns an empty string in its resulting slice,
ever.
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.
Thus far the fuzzers have found a few crashers in the Caddyfile parser. However, the fuzzer have been stuck at import glob expansion after import glob expansion, which aren't reproducible.
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.
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.

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.

* 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.

* 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.
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.
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
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.
Before, listener ports could be wrong because ParseAddress doesn't know
about the user-configured HTTP/HTTPS ports, instead hard-coding port 80
or 443, which could be wrong if the user changed them to something else.
Now we defer port and scheme validation/inference to a later part of
building the output JSON.
Using rewrite is like saying, "I accept this request, but I just need
to act on it as if it came in differently."
Whereas redir implies more of, "I reject this request, send it to me
differently, then I will process it."
Makes sense for it to come before rewrites. This can always be changed
using the 'order' global option if needed.
The fix that was initially put forth in #2971 was good, but only for
up to one layer of nesting. The real problem was that we forgot to
increment nesting when already inside a block if we saw another open
curly brace that opens another block (dispenser.go L157-158).
The new 'handle' directive allows HTTP Caddyfiles to be designed more
like nginx location blocks if the user prefers. Inside a handle block,
directives are still ordered just like they are outside of them, but
handler blocks at a given level of nesting are mutually exclusive.
This work benefitted from some refactoring and cleanup.
This allows individual directives to be ordered relative to others,
where order matters (for example HTTP handlers). Will primarily be
useful when developing new directives, so you don't have to modify the
Caddy source code. Can also be useful if you prefer that redir comes
before rewrite, for example. Note that these are global options. The
route directive can be used to give a specific order to a specific group
of HTTP handler directives.
In the v1 Caddyfile, only the first matching site definition would be
used, so setting these `Terminal: true` ensures that only the first
matching one is used in v2, too.
We also have to sort by key specificity... Caddy 1 had a special data
structure for selecting the most specific site definition, but we don't
have that structure in v2, so we need to sort by length (of host and
path, separately). For blocks where more than one key is present, we
choose the longest host and path (independently, need not be from same
key) by which to sort.
When we append a token to the new dispenser, we need to consume it in the parent, too; otherwise it gets scanned twice, which in this case messed up the nesting count which got decremented once too many times.

This is because of our sequential handling logic which was recently
merged; if vars is the first handler in the chain, it will be run before
the next route's matchers are executed, so there's no need to nest the
handlers anymore.

Caddyfile-generated subroutes have handlers, which are sorted first by
directive order (this is unchanged), but within directives we now sort
by specificity of path matcher in descending order (longest path first,
assuming that longest path is most specific).
This only applies if there is only one matcher set, and the path
matcher in that set has only one path in it. Path matchers with two or
more paths are not sorted like this; and routes with more than one
matcher set are not sorted like this either, since specificity is
difficult or impossible to infer correctly.
This is a special case, but definitely a very common one, as a lot of
routing decisions are based on paths.

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.
