This is just a convenience if using a static_response handler in an
error route, by setting the default status code to the same one as
the error status.
Cache capacity is currently hard-coded at 1000 with random eviction.
It is enabled by default from Caddyfile configurations because I assume
this is the most common preference.

Correct behavior is not well defined because this is a non-standard
header field. This could be a "hop-by-hop" field much like
X-Forwarded-For is, but even our X-Forwarded-For implementation
preserves prior entries. Or, it could be best to preserve the original
value from the first hop, representing the protocol as facing the
client.
Let's try it the other way for a bit and see how it goes.

While building a layer4 app for Caddy, I discovered that we need the
ability to fill a request's context just like the HTTP server does,
hence this exported function PrepareRequest().
* For `roll_size` and `roll_keep_for` directives, round up instead of down.
For example, if a user wants to be able to look back on 36 hours of logs,
but you must round to a 24-hour multiple, then it's better to round up to
48 hours (which includes the desired 36 hours) instead of down to 24 hours.
* `roll_size` had an off-by-one error that caused the size to be as much as
1 MB larger than requested. For example, requests of `1MB` and `1.1MB`
both became 2 MB. Now `1MB` means 1 MB, and `1.1MB` is rounded up to 2 MB.
An upstream like https://localhost:80 is still forbidden, but an addr of
localhost:80 can be used while explicitly enabling TLS as an override;
we just don't allow the implicit behavior to be ambiguous.
When client certificate is enabled Caddy check only last certificate from
request. When this cert is not in list of trusted leaf certificates,
connection is rejected. According to RFC TLS1.x the sender's certificate
must come first in the list. Each following certificate must directly
certify the one preceding it.
This patch fix this problem - first certificate is checked instead of last.
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.

Previously, matching by trying files other than the actual path of the
URI was:
file {
try_files <files...>
}
Now, the same can be done in one line:
file <files...>
As before, an empty file matcher:
file
still matches if the request URI exists as a file in the site root.

Nobody was using it anyway -- it works well, but something got fumbled
in a refactoring *months* ago. Turns out that we forgot the interface
guards AND botched a method name (my bad) - Ok() should have been OK().
So it would always have thrown a runtime panic if it tried to be loaded.
The module itself works well, but obviously nobody used it because
nobody reported the error. Fixing this while we move it to the new repo.
Removing this removes the last Bazaar/Launchpad dependency (I think).
* 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

Sigh, apparently Linux is incapable of distinguishing host interfaces
in socket addresses, even though it works fine on Mac. I suppose we just
have to assume that any listeners with the same port are the same
address, completely ignoring the host interface on Linux... oh well.
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.
Using html/template.HTML like we were doing before caused nested include
to be HTML-escaped, which breaks sites. Now we do not escape any of the
output; template input is usually trusted, and if it's not, users should
employ escaping actions within their templates to keep it safe. The docs
already said this.
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 placeholder in the path component injects a query string such as
the {http.request.uri} placeholder is wont to do, we need to separate it
out from the path.
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.
Either Dial or LookupSRV will be set, but if we rely on Dial always
being set, we could run into bugs.
Note: Health checks don't support SRV upstreams.

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
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.
When using the default automation policy specifically, ap.Issuer would
be nil, so we'd end up overwriting the ap.magic.Issuer's default value
(after New()) with nil; this instead sets Issuer on the template before
New() is called, and no overwriting is done.

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).
