- Channel resolution: resolve by Channel.id first (what the XC API emits
to clients), fall back to provider stream_id for backward compatibility.
Fixes 404 on all timeshift requests from XC clients.
- Stream management: timeshift is now a first-class citizen alongside live
and VOD in the stream-limits system. get_user_active_connections()
detects type='timeshift', attempt_stream_termination() sets a Redis
stop key (same pattern as VOD), and the timeshift view calls
check_user_stream_limits() before connecting upstream. The stream
generator checks the stop key every 100 chunks. Fixes infinite retry
loops on max_connections=1 providers for live→timeshift and
timeshift→timeshift transitions.
- Streaming: replaced HTTPStreamReader thread+pipe with direct
iter_content+yield (same pattern as VOD proxy). The pipe approach
deadlocked under gevent because the reader thread's select() competed
with the greenlet's pipe read for hub scheduling. Throughput went
from ~74 B/s to 13+ MB/s.
- TS preamble: peek now strips pre-sync bytes (PHP warnings, BOM) before
prepending to the stream, preventing corrupt TS output.
- Credential safety: _redact_url() now truncates to scheme://host/...
to avoid leaking XC path-based credentials in logs.
- Tests: updated 5 tests that referenced the removed HTTPStreamReader.
21/21 timeshift tests pass.
- Migration: fixed SyntaxWarning for unescaped regex in 0038.
- 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
