We decided that we'll use branches like `2.4` as the target for any changes that we might want to release in a `2.4.x` version like `2.4.1`, so that we can continue to merge changes targeting the next minor release (e.g. `2.5.0`) on master.
Our CI config wasn't set up for this to work properly though, since it was only running checks on PRs targeting master. This should fix it.
I couldn't find a way to do a pattern to only match digits for the branch names from Github's docs, it just looks like a pretty generic glob syntax. But this should do until we get to 3.0
* 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.

* run gofmt
* fmt: better way of handling edge case
Followup to #4150, #4151 /cc @ueffel @polarathene
After a bit of discussion with @mholt, we decided to remove `prefer` as a subdirective and just go with using the order implicitly always. Simpler config, simpler docs, etc.
Effectively changes 7776471 and reverts a small part of f35a7fa.
* caddyhttp: Fix fallback for the error handler chain
The fix I went with in the end (after realizing some mistaken assumptions in #4131) is to just make the routes fall back to errorEmptyHandler instead of the non-error empty handler, if Terminal is true, making the routes error-aware. Ultimately this was probably just an oversight when errors was implemented at some point in the early betas of v2.
See https://caddy.community/t/problem-with-basicauth-handle-errors/12243/9 for context.
* Revert "caddyhttp: Fix fallback for the error handler chain"
This reverts commit 95b6ac44a6.
* caddyhttp: Fix via `routes.go`
* fileserver: Fix `file` matcher with empty `try_files`
Fixes https://github.com/caddyserver/caddy/issues/4146
If `TryFiles` is empty, we fill it with `r.URL.Path`. In this case, this is `/`. Then later, in `prepareFilePath()`, we run the replacer (which turns `{path}` into `/` at that point) but `file` remains the original value (and the placeholder is still the placeholder there).
So then `strings.HasSuffix(file, "/")` will be `false` for the placeholder, but `true` for the empty `TryFiles` codepath, because `file` was `/` due to being set to the actual request value beforehand.
This means that `suffix` becomes `//` in that case, so after `sanitizedPathJoin`, it becomes `./`, so `strictFileExists`'s `strings.HasSuffix(file, separator)` codepath will return true.
I think we should change the `m.TryFiles == nil` codepath to `m.TryFiles = []string{"{http.request.uri.path}"}` for consistency. (And maybe consider hoisting this to `Provision` cause there's no point doing this on every request). I don't think this "optimization" of directly using `r.URL.Path` is so valuable, cause it causes this edgecase with directories.

* httpcaddyfile: Fix unexpectedly removed policy
When user set on_demand tls option in a catch-all (:443) policy,
we expect other policies to not have the on_demand enabled
See ex in tls_automation_policies_5.txt
Btw, we can remove policies if they are **all** empty.

* 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.
* caddyfile: Add test
An idea that came up in https://caddy.community/t/save-internally-issued-wildcard-certificate-in-consul/11740, this a simple module that might be useful for anyone who uses storage modules that aren't filesystem, to let them load certs/keys externally issued for use by Caddy.
Bit goofy, since we need to fetch the certmagic.Storage during provisioning, it needs a wrapping struct instead of just being an array like `load_files`.
Future work might involve adding Caddyfile support via a subdirective of the `tls` directive maybe?

* address review comments
After reading a question about the `handle_response` feature of `reverse_proxy`, I realized that we didn't have a way of serving an arbitrary file with a status code other than 200. This is an issue in situations where you want to serve a custom error page in routes that are not errors, like the aforementioned `handle_response`, where you may want to retain the status code returned by the proxy but write a response with content from a file.
This feature is super simple, basically if a status code is configured (can be a status code number, or a placeholder string) then that status will be written out before serving the file - if we write the status code first, then the stdlib won't write its own (only the first HTTP status header wins).
Initial sd_notify support was added in #3963, but that sent signals from
both cmdRun and cmdReload. This approach has two drawbacks:
- Reloads initiated via the API do not send signals.
- The signals are sent from different processes, which requires the
`NotifyAccess=exec` directive in the unit file.
This change moves the NotifyReloading and NotifyReadiness invocations to
Load, which address both of those drawbacks. It also adds a
complimentary NotifyStopping method which is invoked from handleStop.
All the notify methods are defined in a notify package to avoid an
import loop.
As of go1.16, the `go` commands will no longer make automatic changes to go.{mod,sum} files (see: https://blog.golang.org/go116-module-changes). This broke the release script which relied on `go mod download` and/or `go build` to automatically generate the go.sum file. This commit explicitly invokes `go mod tidy` to have the go.sum file generated.
My editor automatically changed ioutil.ReadFile() to os.ReadFile() in accordance
with Go 1.16 changes. I didn't notice this until pushing.
But we still have to support Go 1.15 for a little while.
Caddy can now generate and persist its own instance ID, a UUID that is stored in
the data directory.
This makes it possible to differentiate it from other instances in a cluster.
