Two coupled fixes that make catch-up play the requested programme:
1. Try the PATH catch-up form (/timeshift/.../{start}/{id}.ts) BEFORE the
timeshift.php query form. Empirical testing showed some XC providers
return the LIVE stream on the query form (HTTP 200, silently ignoring
`start`) — a valid MPEG-TS indistinguishable from a real archive, so the
cascade accepted it and the user always got live content. The PATH form
actually seeks. Candidate ordering now lives in
build_timeshift_candidate_urls() with the full rationale.
2. Strict-UTC XC API surface + single proxy-time timezone conversion:
- xc_get_epg start/end always UTC, server_info.timezone always "UTC",
time_now UTC — the timezone triple is consistently UTC.
- Removed the global default_timezone setting and the
_convert_xmltv_to_local_timezone rewrite entirely.
- The proxy converts the client's UTC timestamp to the SERVING provider's
own zone (server_info.timezone captured on account refresh, read from
the account's default profile) right before building the upstream URL —
DST-correct via ZoneInfo, no-op for UTC/unknown zones. Verified against
a real provider: it interprets the URL timestamp as its LOCAL wall
clock, so pure UTC pass-through seeks 1-2h off.
- EPG duration lookup keeps the ORIGINAL UTC timestamp (programmes are
stored in UTC) — exactly one conversion in the whole chain.
Also per review feedback:
- Removed the debug_logging toggle — verbose timeshift logging now follows
the standard logger DEBUG level (DISPATCHARR_LOG_LEVEL).
- Removed the dead default_language setting (never read anywhere; the EPG
lang field is hardcoded). TIMESHIFT_DEFAULTS is down to
xmltv_prev_days_override, and the Settings UI shows that single field
with accurate help text.
- Validate the timestamp up front (400 on malformed input) instead of
forwarding it verbatim into the upstream URL.
- Redact the upstream URL in the connection-error log (requests exceptions
embed the full URL, which carries XC credentials).
- URL-encode XC credentials in both URL builders.
- Request identity encoding upstream (the TS-sync peek reads raw bytes).
- Poll the stop key on the 5-second heartbeat cadence instead of every 100
chunks (~25 MB), so stream-limit terminations free the provider slot fast.
- New tests: proxy timestamp wiring (converted value reaches the URL
builder, original UTC value reaches the duration lookup), _redact_url,
decisive 3xx break (anti ban), invalid timestamp rejection; deflaked the
format-cache promotion test (django cache persists across runs).
