TagLib crashes while scanning recording

[J A Brown]

Using Linux 12.10, Mixxx 1.10 Was attempting to record mix from auto dj - 2 hour long set, program crashed 3/4 or way through.

[J A Brown (inisfad)]

(Sorry, I don't know how to 'attach' a file. When Mixxx was finally able to load again, it would play one song half way through and then freeze. Log at time of freeze:

Hm, this is a TagLib crash probably caused by a corrupt WAV/RIFF/AIFF file that is in your AutoDJ queue. Could you check each file in the queue and try to load it individually (without starting AutoDJ) to find which file it is?

[RJ Skerry-Ryan (rryan)]

If you do find the file that caused this could you please either post it here or email it to me? (<email address hidden>) so I can debug further. We may need to report this to TagLib. We have had issues like this in the past and TagLib fixed them. Those fixes should be in the version of TagLib packaged in Ubuntu 12.10 so I believe this is not the same though it is the same stack trace as Bug #1016726.

[Sean M. Pappalardo (pegasus-renegadetech)]

Egads, man. There's a link at the bottom that says "add attachment or patch"

[J A Brown (inisfad)]

The original song of the crash was an mp3. Mixxx began to crash regardless of what song was loaded. And then crashed 30 seconds after starting the program, with no song loaded. If you are interested, I was posting the logs on the MIxxx forum - I was advised to download 1.11 which I did, and the same issue continued. Here is the link, if it's helpful:
http://www.mixxx.org/forums/viewtopic.php?f=3&t=4925

And Sean, thanks for the heads up. Sadly, as I started typing at the top, rather than at the bottom, I didn't see the link until everything was typed/copied. By that time, it was unlikely that I was going to start over.....

[RJ Skerry-Ryan (rryan)]

The song causing the crash is not necessarily the one loaded in a deck. So what might appear like random crashing on any song is actually just that Mixxx crashes when it scans the same problem song in the background.

It is also possible that a failed recording produced a corrupt file and every time Mixxx tries to read the metadata of this corrupt file it triggers the crash bug in TagLib.

Upgrading Mixxx isn't going to help because this is a taglib bug (it's very easy to see in the backtrace that this is the case).

[RJ Skerry-Ryan (rryan)]

Could you try moving all the songs in your recordings folder out of that folder and see if Mixxx still crashes? If that fixes it then it's likely that we wrote a corrupt / half-done recording that causes TagLib to barf while trying to parse it.

[J A Brown (inisfad)]

By the way, a complete uninstall, deletion of configuration files and downgrade back to 1.10.1 has apparently solved whatever the issue was, as now Mixxx is back working as it should.

[J A Brown (inisfad)]

Sorry, I am not terribly computer literate, however......I have had this
play list for about one month, and have been playing it again and again
without any issue. The files are either WAV, FLAC or MP3. The problem
arose yesterday when I attempted to record the entire mix - putting it
all into auto dj, and it crashed 3/4 of the way through. I have
completely uninstalled Mixxx and reinstalled it - this time my library
is only the specific playlist that I was using yesterday. Although I
have not played the entire playlist again, I have randomly played songs,
as well as the song that was on when the crash occurred, without issue.

Seems my comment to the above file is not indicated?? After downloading a new Mixxx download, I only put songs from my playlist into the library, started Mixxx this morning, using Auto DJ and the record function. Mixxx crashed in the middle of the second song. Log is above as mixxx log tuesday. I then tried this, with the same songs, in the same order, without recording, and Mixxx crashed 30 seconds into the first song. Will attach the log for that below, as mixxx log tuesday 2.doc.

[J A Brown (inisfad)]

Now, trying this again, with latency set at 90 whatever, and manually loading the same first song into deck one, manually loading same second song into deck two, playing first song, about 30 seconds it, Mixxx crashes. Log attached below.

[Daniel Schürmann (daschuer)]

Hi JA,

Thank you for your logs.
Please do not attach Microsoft Word documents. They are unhandy.
Use Plain text (*.txt) instead or attach the mixxx.log itself.

Unfortunately the log file is not significant for your crash.

As RJ pointed out, from your back trace it is clear that the crash happens while reading meta data from a specific file.

I am not sure if you think this is still the case or not?
Maybe this bug is caused by two overlapping issues.
If you think this is still the issue I can prepare a version which will be more chatty in th log file when reading meta data.

In any case you should always run Mixxx inside GDB while testing to have the chance to produce an back trace .

Does the crash happens only with those specific songs, or can you trigger the crash with any songs?
Does Mixxx crash without playing?
Does Mixxx crash every time you try to play those songs?

I am currently working on a solution that a crash while reading meta date does not effect the whole Mixxx process.
It would be nice if you could mail, once identified mail your effected songs to <email address hidden>.
So I can test against this issue.

Thank you,

Daniel

[RJ Skerry-Ryan (rryan)]

Thanks for providing more info JA -- in this case I believe the issue is probably that we have written a corrupt recording file and TagLib cannot process its metadata. Could you post the recordings from your recording folder so we can look at them? (or email them to us)

[J A Brown (inisfad)]

Mixxx now crashes within 50 seconds of loading the program. I do not have to be playing anything. Mixxx log attached

[J A Brown (inisfad)]

[RJ Skerry-Ryan (rryan)]

Hi again,

Thanks for the additional data. Every log file you have posted points to the same issue that I mentioned:

1) There is a corrupt audio file that Mixxx is reading.
2) This corrupt file might be a music file of yours or a previously recorded file in your recordings directory.
3) The crash is originating withing TagLib, which is one of Mixxx's dependencies.

As Daniel offered to do, we should get you a custom version of Mixxx that announces right before it reads the metadata of a file. This would help you pin down which of your files (or Mixxx recordings) is corrupt.

[RJ Skerry-Ryan (rryan)]

Once you've found the corrupt file, we can submit it to the TagLib developers so that they can fix the bug. Once they fix that bug it will prevent Mixxx from crashing on corrupt files like this in the future.

[J A Brown (inisfad)]

OK,so what should I do now? As my 'new' library does not contain the entirety of the music files on my computer, would this mean that the corrupt file is within the library (even though it is not in a current playlist)? Mixxx is crashing now whether it is playing, or playing random songs (ie not the same one causing the crash). Do you want my playlist forwarded to you?

Thanks, Daniel. I guess there is no way for me to find out what 0x080721f4 and 0x080984e1 is from my end, eh?? :-).
Looking forward to your download link - I must say I am kind of enjoying this, it's like a mystery puzzle, and assume all will be ready for my 'event' in July. Thanks for your help.

[RJ Skerry-Ryan (rryan)]

I just changed Mixxx 1.11.0 so that when you run it with the --developer
flag it will print what files are being processed by TagLib before
processing them. This way when you see Mixxx crash the log file will tell
us which file was being processed.

It's in the 1.11 branch revision 3811. If you look here there should be
Ubuntu .deb files produced that you could try:
http://builds.mixxx.org/builds/release-1.11.x/r3811

You probably want the precise_i386 or precise_amd64 .deb files.

Run Mixxx with the "--developer" flag to turn on this logging and try to
get it to crash.

I just want to re-iterate -- Mixxx does things in the background. Just
because you loaded or didn't load a particular file (e.g. from Rhythmbox or
from a playlist) doesn't mean Mixxx will not crash by reading it. In
particular, files in your recording folder are processed by Mixxx at
startup so if a corrupt file is in there then it could cause Mixxx to crash
after a certain period of time regardless of whether you load a file.

Also, the crash is caused by you running out of memory. TagLib spins out of
control in an infinite loop until it consumes all available memory. This
means that when you load a problem track it could take minutes to hours
before the crash occurs depending on how much free memory you have.

Thanks for the info. Please advise of the following:

Do I uninstall the current Mixxx program prior to installing the new one, and if so, is uninstalling the old program through Ubuntu Software Center sufficient??

Will running the new Mixxx program with the --developer flag be self explanatory, or if not, where do I find this flag? Allow me to reiterate that I am not a programmer and have little experience in these matters. Thanks to advise!!

[RJ Skerry-Ryan (rryan)]

I think that you should be fine with just installing the deb (it should
replace the old version) but uninstalling first in the software center is a
good idea just to make sure.

To enable the developer flag, just run Mixxx like you did with GDB before
except with --developer added when you type "run". Note there are two
dashes before developer.

1) gdb mixxx
2) run --developer

[Daniel Schürmann (daschuer)]

Thank you RJ for the patch! Just noticed that I have now twice the message on my system ;-)

@JA It should be possible to install the new version without remove the old. The Mint software center should do all the work for you. Just double click the *.deb file for your system.

If that not work for any reason you van install the *.deb from a terminal command line:
sudo dpkg -i mixxpackage.deb
replace mixxpackage.deb with the path to the just downloaded package.
Rightclick copy in nemo and Shift+Ctrl+V in terminal.

To start Mixxx in development mode you have to do it from command line as well:

just type:
mixxx --developer

Perfect! This is the offending file:

/home/jane/Music/New playlist/Mixxx/Recordings/2013-04-09_12h:26m:49s.wav

Could you post it here or email it to me (<email address hidden>)?

[J A Brown (inisfad)]

I must tell you that this is a bit weird. I believe that this recording file was done today, when I did a clean install of Mixxx, and tried to record my playlist again.
This entire issue started a couple of days ago, when I tried to record my 2 hour playlist. If you recall, the program worked and apparently recorded until 1 hour and 45 minutes into the playlist, when it then crashed. So is it possible that the problem is actually with the recording process?? This file is 36mb, and I can't email it. Will try uploading using the link below....If this doesn't work, can I compress it and send it??

[RJ Skerry-Ryan (rryan)]

As long as you compress it using a zip file or tar archive. If you compress
it into an MP3 or something then the corruption probably won't be
maintained.

It has happened before that Mixxx fails while recording and which leaves a
corrupt file in your recordings folder. When Mixxx starts up again it will
try to read this file. TagLib has a bug such that if it tries to read a
corrupt file like this, then it infinite loops and uses all the system
memory until Mixxx crashes while allocating memory.

I was able to upload it onto the website as a WAV file. Hopefully it's
ok. Let me know if there is anything further you want me to do - I am
in Ireland, so presumably some hours ahead of you - it's almost bedtime!!

I also wrote on the website that this issue actually started two days
ago, when I tried to record the entirety of my 2 hour play list. At 1
hour/45 minutes, the program crashed. So perhaps the issue is with
recording in some way??

Thanks for all your help.

Please be good enough to advise if, while waiting for the 'fix' for this issue, if I just delete this file, will I be able to use the program normally?? And, will I be able to record a set, or is the issue with actual recording?? Thanks.

Perhaps in the programmer's world, you are not supposed to thank someone for providing a fix for an issue, but I received an email last night that this issue had been fixed in the current release. So, thank you!

I think we can call this fixed. TagLib's latest release does not crash on this file so Mixxx doesn't either.

Thanks J A Brown!

BTW for others reading this report the resolution is to upgrade your version of TagLib.
