From ac2d5c95014b4f344e4c8d329c981afdc45a013a Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 12 Nov 2025 10:32:47 +0000 Subject: [PATCH] Fix REAL bug: HTTP timeout was truncating Radio Paradise blocks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ROOT CAUSE IDENTIFIED: The previous "wait for playback duration" workaround was masking the real issue. Radio Paradise blocks last ~20 minutes (1200s), but the HTTP timeout was only 180 seconds, causing premature stream termination. With backpressure from the audio pipeline, HTTP download proceeds at real-time pace. A 20-minute block takes ~20 minutes to download. The 180s timeout was killing the connection after 3 minutes, resulting in incomplete blocks. Changes: 1. **Increase HTTP block_timeout: 180s → 7200s (2 hours)** - Allows complete download of even the longest blocks - Comment explains why such a long timeout is needed 2. **Increase MPSC channel sizes: 16 → 60 chunks** - Matches TimerNode max_lead_time (3.0s / 0.05s = 60 chunks) - Prevents stop-and-go backpressure pattern - Allows smooth buffering as intended 3. **Replace workaround with proper channel drainage** - Use tx.closed().await instead of sleep() - Guarantees all buffered chunks are processed - More architecturally sound solution 4. **Add comprehensive diagnostic traces** - Log expected vs actual block duration - Detect premature EOF (< 95% of expected duration) - Track bytes decoded and HTTP Content-Length - Monitor backpressure blocking with timing This fixes the streaming completely. The block will now: - Download for the full ~20 minutes (real-time with backpressure) - Decode all audio data without truncation - Process all chunks before pipeline shutdown --- pmoparadise/examples/stream_block.rs | 23 +++-- pmoparadise/src/client.rs | 5 +- .../src/radio_paradise_stream_source.rs | 89 ++++++++++++------- 3 files changed, 75 insertions(+), 42 deletions(-) diff --git a/pmoparadise/examples/stream_block.rs b/pmoparadise/examples/stream_block.rs index 894e555a..43fbaea8 100644 --- a/pmoparadise/examples/stream_block.rs +++ b/pmoparadise/examples/stream_block.rs @@ -208,11 +208,18 @@ async fn main() -> Result<(), Box> { source_flac.push_block_id(block.event);
