This update addresses a critical issue where geventpool database connections were not properly released during stream setup and teardown, potentially leading to resource exhaustion. The `close_old_connections()` method is now consistently called in `finally` blocks across various components, ensuring that connections are released even in the event of exceptions. Additionally, the logic for resolving channel and stream names has been improved to prioritize caller-supplied names and Redis values, reducing reliance on ORM during initialization. This change enhances performance and stability, particularly in high-load scenarios. Tests have been updated to validate these improvements.
Add end-to-end catch-up support for XC clients and native apps: provider
proxy with failover and per-viewer session pooling, REST session minting
for tokenless playback URLs, catch-up admin stats, combined connection
stats, and Stats UI with dedicated cards plus websocket updates.
Includes Redis namespace consolidation under timeshift:* (dropping legacy
timeshift_ id prefixes), dedicated catch-up stop by session_id, and
cleaner channel/client metadata split for stats keys.
Closes#133
Adds native catch-up/timeshift replay for Xtream Codes providers through
the same HTTPStreamReader transport pipeline as live TV.
Timeshift proxy (apps/timeshift/):
- URL cascade: 3 candidate timestamp formats per provider, per-account
format cache for fast-forward seek performance
- MPEG-TS preamble stripping (shared with HTTPStreamReader)
- Stats integration: timeshift viewers appear on /stats with TIMESHIFT badge
- Auth via hmac.compare_digest on XC password
Catchup detection — denormalized for zero-cost output queries:
- Stream.is_catchup + Stream.catchup_days populated at XC import time
- Channel.has_catchup + Channel.catchup_days + Channel.catchup_provider_stream_id
rolled up via ChannelStream post_save signal (UI path) and explicit SQL
after bulk_create (import path)
- _xc_channel_entry() reads denormalized fields instead of per-channel
custom_properties JSON introspection (eliminates N+1 queries)
- Migration 0038 backfills existing data via raw SQL
XC API enhancements:
- server_info.timezone + start/end + time_now use configured timezone
(triple consistency rule — fixes wrong-programme-plays bug)
- Dynamic has_archive flag + auto prev_days for catch-up channels
- XMLTV timestamps rewritten to local timezone for catch-up clients
HTTPStreamReader extended (apps/proxy/live_proxy/input/http_streamer.py):
- 1 MB pipe buffer via fcntl F_SETPIPE_SZ (eliminates producer/consumer
ping-pong that halved throughput)
- Pre-opened response= for URL cascade workflows
- strip_ts_preamble= for XC servers emitting PHP warnings before TS
- find_ts_sync() as shared utility
- Builds on upstream O_NONBLOCK + select() write loop
Provider stream_id lookup order:
- stream_xc() and xc_get_epg() try internal Channel.id first, fall back
to provider stream_id only when needed (avoids unconditional query on
every request)
Also includes:
- VOD provider cascade in stream_vod() — iterates all M3U relations by
priority when first provider is at capacity
- Defensive null-safety: custom_sid: None → "" in get_live_streams,
get_vod_streams, get_vod_info, get_series_info (fixes iPlayTV crash on
JSON null for string fields)
- Timeshift settings UI (timezone selector, debug toggle)
- StreamConnectionCard violet TIMESHIFT badge
- Orphan cleanup skips timeshift_* virtual channels
- channel_status.py: fold output_format and output_profile_id into the
existing hmget, reducing per-client Redis calls from 3 to 1
- utils.py: collapse 2x and 3x hget per key in scan_iter loops
(get_user_active_connections) to single hmget calls
- views.py: replace 3x hget on channel metadata in the worker-join path
of stream_ts with a single hmget
