[2.11.2 Regression] {block} is ignored when imported from a separate file #7557
Description
Issue Details
Description
When importing a snippet from a separate file that contains a directive wrapping a {block} placeholder (such as reverse_proxy), Caddy v2.11 silently ignores the provided block during the import.
This bug only seems to happen if the snippet is in a separate file.
Steps to reproduce
./Caddyfile
{
admin off
auto_https off
}
import snippets
:8080 {
import test {
this_is_nonsense
}
}
./snippets
(test) {
reverse_proxy {
{block}
}
}
run
docker run --rm -p 8080:8080 -v "$PWD:/etc/caddy:ro" caddy:2.11 caddy run --config /etc/caddy/Caddyfile
Expected Behavior (Caddy v2.10)
In Caddy v2.10, the {block} is injected correctly. The parser evaluates the contents, sees the invalid this_is_nonsense subdirective inside reverse_proxy, and rightfully refuses to start:
$ docker run --rm -p 8080:8080 -v "$PWD:/etc/caddy:ro" caddy:2.10 caddy run --config /etc/caddy/Caddyfile
Error: adapting config using caddyfile: parsing caddyfile tokens for 'reverse_proxy': unrecognized subdirective this_is_nonsense
Actual Behavior (Caddy v2.11)
In Caddy v2.11, the {block} is entirely ignored. The reverse_proxy directive evaluates as empty, so Caddy happily starts up with no errors.
