* fix(plugins): build public URLs on the caller's address instead of localhost
The artwork host service had no `*http.Request`, so it passed `nil` to
`publicurl.ImageURL`. With neither `ShareURL` nor `BaseURL` configured, that
produced `http://localhost/share/img/...`, which is useless to anything outside
the server. The Discord Rich Presence plugin explicitly drops localhost URLs, so
it fell back to the Navidrome logo instead of the real cover art.
`serverAddressMiddleware` already works out the client-facing scheme and host
from the `X-Forwarded-*` headers. It now also records them in the request
context, and `publicurl` takes a `context.Context` instead of an `*http.Request`
so any caller can reach them. Extism passes the caller's context through to host
functions, so plugins invoked during a request now get a reachable URL with no
configuration.
Switching the parameter also removes the need for a second, parallel entry
point: the package previously wanted only a scheme, a host, and a context, and
took a whole request to get them. `AbsoluteURL` no longer dereferences a
possibly-nil request on its parse-error path.
Plugin calls that start from `context.Background()` (scheduler and websocket
callbacks, the buffered scrobble drain) still fall back to localhost, since they
have no request to learn from. A debug log now points at `ShareURL` when that
happens.
* fix(publicurl): include the configured port in the localhost fallback
The last-resort fallback built `http://localhost/...`, which points at port 80
and so is unreachable for a server listening anywhere else — the default 4533
included. Use `conf.Server.Port` so a consumer on the same machine can actually
fetch the URL.
* fix(publicurl): use https in the localhost fallback when TLS is configured
The fallback hardcoded the http scheme, so a TLS-only server with no BaseURL
advertised a URL it does not answer on. Mirror the server's own switch, which
requires both a certificate and a key.
* refactor(publicurl): tidy the localhost fallback and its tests
Use gg.If for the fallback scheme so it reads as an expression, like the
BaseScheme branch above it, instead of assigning http and overwriting it.
Drop two tests the ctx refactor left redundant: one asserted PublicURL "works
without a request" but became a byte-identical copy of the ShareURL spec once
the *http.Request parameter went away, and the two port specs differed only in
the integer, where the non-default port is the stronger assertion.
* refactor(conf): add TLSEnabled and use it instead of repeating the predicate
Whether the server speaks HTTPS was decided inline in three unconnected
places. This PR added the third, in a URL-building package that has no
business inferring the transport config.
Move the rule to conf, next to the fields it derives from, and call it from
publicurl and the insights collector. server.Run keeps its own expression: it
takes the certificate and key as parameters, and its test passes values that
do not come from the config.
* refactor(req): drop redundant error return from Strings
The error from Strings carried no information beyond emptiness — it fired
exactly when the param was absent — and nearly every caller discarded it with
a blank identifier. Strings now just returns the values (empty when absent),
making the common optional-list reads one clean expression.
The few required-param callers (scrobble, createShare) check for emptiness and
return the same Subsonic error code 10 as before; their e2e tests now pin that
code. Ints and Times keep their contracts by synthesizing ErrMissingParam
themselves, so selectedMusicFolderIds is untouched. The jellyfin parseFields
helper is inlined away, since ParseFields(p.Strings("fields")...) now
compiles directly.
