Description robert marshall 2014-05-04 16:00:19 UTC

I've seen around 3 crashes of amarok today all when finishing playback of a track and with a dynamic playlist active. 

--debug gives me

(vlc 0.6.2)
I assume there's a track somewhere in my collection that amarok doesn't like and when it tries to add it to the playlist it crashes?

(I've not attempted the repair to table urls mentioned in the --debug output - do I need to or does it happen automatically when amarok finds the marked table?)

Reproducible: Sometimes

Comment 1 Christoph Feck 2014-05-04 16:46:59 UTC

> Assertion 'pa_close(fds[0]) == 0' failed at pulsecore/core-util.c:2459, function pa_close_pipe(). Aborting.

Looks like a problem with pulseaudio. To be sure, we need the backtrace of the crash, with debug symbols enabled. For more information, please see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Comment 2 Myriam Schweingruber 2014-05-04 18:09:51 UTC

Setting status correctly. Please also make sure all the disks and shares where the dynamic playlist gets the tracks from are not down or unavailable.

Comment 3 robert marshall 2014-05-04 20:20:47 UTC

Though Christoph suggests the problem is with pulseaudio (or can both be true?) The whole collection is within $HOME (with no soft links within it to other file systems)

I'm running a version compiled from git so if Dr Konqi fails to run again, I'll try to get a core dump and proceed from there

Comment 4 Myriam Schweingruber 2014-05-05 09:12:56 UTC

We will see. Since I am waiting for a backtrace, please leave the status :)

Comment 5 robert marshall 2014-05-18 11:31:38 UTC

Here it is, I'll leave the gdb session around and create a core in case anything else is needed

Comment 7 Myriam Schweingruber 2014-05-18 14:20:35 UTC

Well, you should install debugging symbols for pulseaudio as well, else there is not much we can find.

Comment 8 robert marshall 2014-05-18 16:48:29 UTC

OK, sorry - I assumed that if the thread which had crashed had all symbols it was ok. I've now installed pulseaudio dbg and will lie in wait (for another 2 weeks maybe!)

Comment 9 robert marshall 2014-05-20 09:17:13 UTC

Here's another crash, same user actions (though again at a different location?)
I'm also including the --debug output
amarok: BEGIN: void Podcasts::PodcastReader::slotAddData(KIO::Job*, const QByteArray&)

Comment 10 Myriam Schweingruber 2014-05-20 11:36:01 UTC

The latest output shows no debugging symbols for Amarok, did you compile it with debugging enabled?

Comment 11 robert marshall 2014-05-20 12:21:42 UTC

I think so, last time I did a cmake (looking at my .bash_history) I have
cmake -DCMAKE_INSTALL_PREFIX=$HOME/kde -DCMAKE_BUILD_TYPE=debugfull $HOME/devel/amarok
Which bit of the bt are you referring to, eg in thread 7 I see

#6 0xb73ac346 in Dynamic::BiasSolver::addTracks (this=0xaac26b8, list=0xa495117c) at /home/robert/devel/amarok/src/dynamic/BiasSolver.cpp:177

which looks as if -g was applied?

nvm, my bad, I was looking at thread 8 and 6 where there are no line numbers

New crash information added by DrKonqi

amarok (2.8.0) on KDE Platform 4.12.5 using Qt 4.8.6

- What I was doing when the application crashed:

Playing a dynamic playlist and told it to stop on a track when it ws done playing.

Comment 14 Myriam Schweingruber 2014-06-08 09:40:41 UTC

Do we have steps how to reproduce this reliably? Not sure the backtraces are really helpful.

Comment 15 Eric Mesa 2014-06-21 01:34:13 UTC

For me it's what I put in my crash: Playing a dynamic playlist and told it to stop on a track when it was done playing.

Comment 16 robert marshall 2014-06-21 07:00:00 UTC

But - at least for me - it's not reliably replicable - I get a spate of crashes and then it doesn't happen again for maybe a week in spite of my often getting it to stop at the end of a track when dynamic playlist is active. It suggests it's something to do with the track that dynamic playlist is about to add (I use lastplayed > 6m) but being random replicating is hard.

Is there any benefit to looking at variable contents within gdb when the crash has happened - or is it likely that there's been some memory corruption some time before?

That is the problem: it never crashes for me, even after trying for about 10 times. Using Amarok from git v2.8.0-339-g411509d

We already have the necessary backtraces, the problem is to replicate the bug reliably, and that simply doesn't happen here. I have yet to see a crash happen when I stop after a track in a dynamic playlist or when I add a track to a dynamic playlist that is running.

Comment 19 robert marshall 2014-06-21 11:26:44 UTC

I was really asking for pointers to likely suspect variables once I have a crashed amarok in gdb so I can do some debugging. Will see if anything leaps out at me.

I've had 2 crashes this morning which I *think* maybe the same problem, where I removed an album (the same album) from the playlist while amarok was playing (*without* stop at end of track being active) and dynamic playlist was active. Inevitably the 3rd time I tried it it didn't crash :-( Something to do with a track being added to the playlist at an 'unexpected' time?

In case it's relevant I have 'start playing when tracks are added to playlist'  unselected.

Comment 20 robert marshall 2014-07-03 19:25:32 UTC

My suggestion as to where the bug lies here is that if the dynamic playlist is unable to provide the next track and stop at end of track is active then it is more likely (but not always?) to crash.

I had a dynamic playlist which was likely to block (yes I know why it was doing so!) and I've changed it so that it is less likely to block and *it seems* that crashes are rarer.
My original dyn playlist was
Match all
      not Genre:"Opera"
      and Match sequentially
              The next track from the album
              else Search for: tracknumber:1
       and lastplay:>6m      
This blocks when one track from the album has been played more recently than 6 months and the earlier ones haven't (yes I need to fix that sometime by changing the logic of my playlist...)

Eric do you have dyn playlists that block - because amarok can't find a track which satisfies the conditions? And are the crashes in places where that may have happened? Myriam do you have dyn playlists which keep on providing candidate tracks and don't block?

Comment 21 Eric Mesa 2014-07-12 18:46:50 UTC

I do have playlists like that, but my crashes were not from one of those.

Comment 22 Myriam Schweingruber 2014-08-11 14:20:51 UTC

Sorry to pick this up so late:

I use a very basic dynamic playlist, asking for random tracks to be fed that have a rating above 3, no genre restriction. So far I haven't been able to reproduce any of these crashes.
Maybe a hardware related issue? My system runs on an ssd, and the tracks are on an external USB 3.0 hard disk, so over all it is all rather fast access. My thinking is that maybe some access delay to a track could be causing the crash?

Comment 23 robert marshall 2014-10-07 07:50:15 UTC

My guess is that corruption is happening somewhere before the crash location so here's the output of running with -d from where I removed a track from the playlist - which forced the generation of an additional track from the dynamic playlist. Just in case it's of assistance!

Is the amarok:       [WARNING] [Bias] Received more results than expected. 
of significance? I sometimes see when a track is removed from the playlist (by one scrolling off the top) the number of tracks shoot up and then come down again when the next (just one!) dynamically added track is added

Do you still see these crashes?

Comment 25 Eric Mesa 2015-01-30 01:45:54 UTC

Most recently did not crash my system. Will let you know if that changes.

Robert, how about you? Would be nice if I could close this one, as I am preparing for an Amarok 2.9.0 release in a few days

Comment 27 robert marshall 2015-01-30 07:56:42 UTC

I'd stopped using 'Stop playing after this track' because of its potential to crash (or nearly so). I've being trying it again fro the last week I've had a crash but it didn't quite fit the pattern. I think it can be closed will see if I can get a better fix on it with 2.9.0
Is the warning I posted back in october ' [WARNING] [Bias] Received more results than expected.' likely to be a crash precursor or is that situation well handled once it occurs?

I have no idea, it doesn't crash for me when I listen to my podcasts (downloaded ones), and I use this quite frequently. Mind you, there were changes to the code since October,  the database has been worked on repeatedly in December.

Comment 29 Myriam Schweingruber 2015-04-18 12:25:20 UTC

Robert, can you still reproduce this? I use the "Stop after this track" feature very frequently and haven't seen a crash.

Comment 30 robert marshall 2015-04-18 13:09:06 UTC

Yes I'm still seeing crashes. I think the 'stop at end of track' part is a red herring, my understanding of how to produce a crash is as follows:
- set dynamic playlist active
- see that the playlist contains tracks where there's a companion track (eg I've have lots of preludes & fugues, dyn playlist chooses the prelude but not the fugue) that isn't there so I drag it out of the collection (while amarok is playing) into the middle of the playlist next to the associated track. 
- there's now more tracks in the playlist than specified in the settings so after the current track dynamic playlist doesn't add a track to the end of the playlist
- after the next track the length is back to the expected length and at this point amarok is very liable to crash
- I think the dyn playlist needs to be fairly complex, I tried with a simple one and couldn't generate a crash. Is pasting/attaching  a dynamic playlist to the bug report likely to be helpful?

I think all the above is mentioned in the various updates though (IMHO) the bug title is wrong, I suggest 'and asked to stop at the end of a track' be removed from the title?

Comment 31 Myriam Schweingruber 2015-04-18 14:50:45 UTC

Could you also provide a recent backtrace? Since there were database updates in January it might be helpful

Comment 32 robert marshall 2015-05-02 20:01:16 UTC

I've managed to replicate this 4 times this evening, in each case the stack was trashed, crash handler just said
Application: Amarok (amarok), signal: Segmentation fault
run under gdb with same result. I can't narrow down precisely what causes it, but with dynamic playlist active I dragged a track to the end of the playlist, added a few more tracks (dragged again) then added a track (dragged twice) and then removed the first of those duplicated tracks. At this point amarok crashes. In some cases I had to repeat this a few times to get the crash. the dynamic playlist only attempts to add a new track at the point where I do the attempted removal

I'm not sure why it claims the track I'm removing isn't known to the collection (though is this dynamic playlist attempting to remove this track  on scrolling upwards (and the output is caused by bug https://bugs.kde.org/show_bug.cgi?id=343956 ) the track I was adding twice and then removing (one) is

the playlist

this playlist often blocks (I realise why!) which maybe is the provoker of the crash?

Comment 34 Ralf Engels 2015-05-02 20:28:42 UTC

Thanks for the analysis. Will have a look when I have time.

Comment 35 Myriam Schweingruber 2015-08-05 22:06:36 UTC

setting status correctly.

Comment 36 Justin Zobel 2020-12-17 05:21:29 UTC

Thank you for the crash report.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.

Comment 37 robert marshall 2020-12-21 20:32:38 UTC

I'm still seeing this - maybe I need to give it a new traceback as it was reported against a rather elderly version!

Comment 38 Tuomas Nurmi 2024-12-06 11:54:50 UTC

This feels like something that might have gotten fixed by the various querymaker changes during the last months. Have you experienced this with 3.1.71-git (=after late October)?

Comment 39 robert marshall 2024-12-06 12:59:58 UTC

I've not seen this crash for ages, I think it can be closed!
