MusicPlayerDaemon/MPD

Shuffling the queue after the next song is queued results in an infinite loop

Opened this issue · 3 comments

Bug report

Describe the bug

If I shuffle the play queue while a song is playing and the next song is queued, mpd hangs in a full-CPU loop. It still responds to play commands, does not burn CPU if paused, and the issue goes away if you press Next or Prev.

Expected Behavior

mpd plays the queued song or the next song in the new shuffled order.

Actual Behavior

mpd hangs. gdb indicates the backtrace is in MainConfigured, sometimes -> EventLoop::Run.

Log

mpd shuffle hang.txt

I can't reproduce this and I need more information on where it hangs. For example with a strace (of all threads with time stamps) or a perf report.

I can reprodude this consistently by:
While a track is playing seeking to a few seconds before the end of a track, then setting random 1.
Then the track finish playing but MPD doesn't start playing the next track.
The status remains in state play and the at the same elaplsed time.
MPD still responds to status command.
Now, setting random 0 it starts playing the same track again from the begining.
(same if changing random from 1 to 0.)

Status:

OK MPD 0.24.0

Looks like when changing the next song (shuffle, random) and the decoder has already finished with the current song (near the end of playing the song), it is necessary to restart the decoder for it to start the new-next song.

Restoring the code that was removed in the player thread in revision 57212d5 solves the issue. But I'm not sure if it's the right solution. May be restarting the decoder when the next-song is actually changed is better.
