Writing down what each endpoint actually guarantees made the places it didn't obvious — shell arguments reaching a crontab or a bash -c unescaped, master.conf written without tmp+rename, and conf edits that could be saved without ever being parsed.

|
// PURPOSE
|
|
// Active media sessions endpoint. Normalised now-playing across every Emby, Jellyfin and
|
|
// Plex instance configured for this host, for the monitor page's session panel.
|
|
//
|
|
// DESIGN PRINCIPLES
|
|
// Thin transport. Discovery, per-server API dialects and normalisation all live in
|
|
// include/media.php; this file only sets the content type and encodes the result.
|
|
//
|
|
// No parameters. Which servers to ask is derived from conf, not from the request, so the
|
|
// browser cannot point this endpoint at an arbitrary URL.
|
|
//
|
|
// OPERATIONAL SAFEGUARDS
|
|
// Bounded by the library's 3s per-request timeout.
|
|
// A wedged media server cannot hold this endpoint open, because every fetch inside
|
|
// vv_media_sessions() carries a stream-context timeout. This is the only thing between
|
|
// a hung Emby and a poll that never returns.
|
|
//
|
|
// Failure is an empty list, not an error.
|
|
// Unreachable servers, non-JSON bodies and unexpected shapes all resolve to [] inside
|
|
// the library. The panel renders empty and the rest of the monitor page is unaffected.
|
|
//
|
|
// Read-only. Sessions are observed. Nothing here stops a stream, forces a transcode, or
|
|
// messages a client.
|
|
//
|
|
// REQUEST
|
|
// GET, no parameters
|
|
//
|
|
// RESPONSE
|
|
// vv_media_sessions() verbatim — a flat list of normalised sessions across all servers
|
|
//
|
|
// DEPENDS ON
|
|
// include/media.php vv_media_sessions()
