Mixxx crashes on first time jog wheel touch + movement after fresh start of macOS

I get sporadic segmentation fault crashes during normal playback of one deck at my gigs. The second deck has a loaded but stopped track in it. The crash can happen after 1 hour of playing or after 4 hours. I could't figure out any special step to reproduce the crash yet and normally it happens only after a long time of playing. That's why I don't have any backtrace data yet. The last time the crash happened, it happened twice within a short time period as the Auto-DJ was active.

Mixxx: 2.1.0-beta1 (build 2.1 r6501) OS: Apple macOS High Sierra 10.13.3 (17D47) CPU: 1,6 GHz Intel Core i5 Video: Intel HD Graphics 6000 1536 MB Sound: Apple Core driver -> Pioneer DDJ-SX

Another problem I have (and I don't know if it's the origin) is that such segmentation fault crashes also occur after a fresh start of macOS and a fresh start of Mixxx during the first touch and movement of a deck's jog wheel (scratch). I'm using the Pioneer DDJ-SX, the Hercules DJ Console RMX4 or the Hercules DJ Console 4-MX. But this occurs only on this macOS. I have an older MacBook with macOS 10.12 (I think) where the first touch doesn't allow any scratching. It only holds the track. On the second touch I can scratch.

I attached the macOS error report after crashing as the Auto-DJ was active.

The crash is most likely caused by a known bug in the 2.1 beta release. Sorry for that, the fix is still pending to be merged: https://bugs.launchpad.net/mixxx/+bug/1749800

Now that the fix for lp:1744550 is merged, please test the current version again.

The second issue seems to be unrelated to the fix, but the crashes during regular usage should be fixed. I just noticed that I pasted the wrong URL and referenced this same bug report ;)

We should change the title to match the second issue and keep this bug report open until the remaining issues are fixed.

Thank you for the information! I renamed the title according the second issue. I hope I can find time on the weekend to focus on that issue and get some backtrace data.

I was able to reproduce the crash!

Conditions:

• Fresh macOS start
• Connected midi controller
• Mixxx is started with internal sound card configured as sound output in the settings

Actions after starting Mixxx:

• Before doing anything else, I change the sound output in the settings to my external controller sound card
• Apply the changes and close the settings window
• Load a song to Deck 1
• Start playback of Deck 1 (by pressing play on the skin or on my controller)
• During playback I touch/press the jog wheel on my controller for the first time and try to move it.

Results (2 behaviors):

1. Playback is stopped as long as I touch the jog wheel but as I move the jog wheel nothing will happen (expected behavior is scratching). On releasing and touching the jog wheel again I am able to scratch.
2. Playback is stopped and Mixxx crashes!

I was able to create back-traces for the crash:

Add: In this case I used the following midi controller: Hercules DJ Console RMX 2. But the crash occurs with my Pioneer DDJ SX and my Hercules DJ Console 4 MX, too.

For easier analysis I attached the back-trace as rtf file.

I used the latest beta build: 2.1.0-beta1 (build 2.1-r6518) for reproducing the crash.

Can anyone else reproduce this? I have no controllers with jog wheels to test with.

[mixxxbot]

Commented by: Be-ing Date: 2018-03-22T22:39:35Z

Results (2 behaviors):

1. Playback is stopped as long as I touch the jog wheel but as I move the jog wheel nothing will happen (expected behavior is scratching). On releasing and touching the jog wheel again I am able to scratch.
2. Playback is stopped and Mixxx crashes!

I am a bit confused by this description. When exactly does it crash? Does it only crash when touching the jog wheel for the first time on some occasions or every time?

In the future, please attach logs and backtraces as plain text files rather than RTF.

Ok, a more detailed description:

Crashing case:

Conditions:

• Fresh macOS start
• Connected midi controller
• Mixxx is started with internal sound card configured as sound output in the settings

Actions after starting Mixxx:

• Before doing anything else, I change the sound output in the settings to my external controller sound card
• Apply the changes and close the settings window
• Load a song to Deck 1
• Start playback of Deck 1 (by pressing play on the skin or on my controller)
• During playback I touch/press the jog wheel on my controller for the first time and try to move it.

Result: Mixxx crashes as soon as I try to move the jog wheel (jog wheel is still pressed to use the scratch function).

If Mixxx has crashed and I restart Mixxx without restarting my MacBook, the result during the first jog wheel touch including movement can be another crash or the playback just stops during jog wheel movement. As soon as I release the jog wheel and press and move it again...the scratch function works as expected. I could reproduce this behavior on two different MacBooks and three different midi controllers. I just could figure out any structure of what happens after the first crash and restart of Mixxx (crashing or just stopping playback during first scratch).

Does it also happy if you try to scratch waveforms by mouse?

Can you watch the memory that is consumed by Mixxx?

Does anyone know why we have no debug symbols included in the Mac version?

I could not reproduce the crash using 2.1.0-beta1 (build 2.1 r6543), macOS 10.13.3 , Vestax VCI-300

CoreAudio 44100Hz @11.6ms Output= VCI 300 Input=None

Followed step by step as outlined in #⁠12.

@max

• Have you any other inputs/outputs active in Preferences > Sound hardware ?
• Have you multiple controllers connected, and active within Mixxx ?
• Have you customized your controller scripts, or loaded the stock scripts from Preferences > Controllers?

If you launch Mixxx from the terminal /Applications/Mixxx.app/Contents/MacOS/Mixxx --developer --controllerDebug and make it crash again, can you post the output from the terminal...

@Daniel: By trying to scratch waveforms by mouse it doesn't crash. Just the expected behavior. The memory consumed by Mixxx is about 630 MB to 750 MB just before the crash.

@jus: My sound configuration at Mixxx startup is: CoreAudio 44100Hz @9.00227ms (Audio buffer setting 2.9ms) Only Master = Build-In output Channel 1-2

Then before playing any song, I go to the settings after Mixxx startup and change the sound configuration to: CoreAudio 44100Hz @4.96559ms (Audio buffer setting 2.9ms) Master = DJConsole Rmx2 Channel 1-2 Headphones = DJConsole Rmx2 Channel 3-4

This configuration is equal to my other DJ/Midi Controllers (Hercules DJ Console 4-MX, Pioneer DDJ-SX).

Then I load a song to Deck 1, press play and try to touch and move the jog wheel. As soon as I move the jog wheel Mixxx crashes.

I have just one controller connected at a time. The crash happens with the stock controller scripts and my customized scripts.

If I launch Mixxx from the terminal using "/Applications/Mixxx.app/Contents/MacOS/Mixxx --developer --controllerDebug" I was not able to reproduce the crash anymore. In this case the scratching works at the first time touching and moving the jog wheel (as expected). In the past I had the crash using the terminal, too.

Are you able to compile Mixxx yourself using the optimize=off option with scons to get a backtrace with debugging symbols? https://mixxx.org/wiki/doku.php/compiling_on_os_x

[mixxxbot]

Commented by: daschuer Date: 2018-03-26T18:30:02Z

Don't use optimize=off Mixx will be unusable slow. The optimize flag does not set or remove the debug symbols. It could be the debug flag. But I can remember that we have decided to always pack the symbols with Mixxx. Isn't this the case fro Mac?

I'm sorry @Be but I am still not able to compile Mixxx myself as described here: https://www.mixxx.org/forums/viewtopic.php?f=3&t=9348

It would be great if I could get the compile process running at some point. Under Fedora it's working as described.

Using optimize=native removes the debugging symbols for me with GCC on GNU/Linux. I have to use optimize=off for backtraces to be helpful. I do not notice any appreciable difference in speed between optimize=off and optimize=native.

@max

Reading the forum thread #⁠19, i understand that you try to compile by using QT5, and it failed.

The following steps should allow you to compile the mixx source with qt4. This works for me since ages, currently with macOS 10.13.3. Qt4 is the mixxx default, qt5 support still experimental.

• Install qt4

  brew tap cartr/qt4 brew tap-pin cartr/qt4 brew install qt@4

• Delete scons cache (from mixxx build dir root)

  scons --clean

  manually remove the following files

  .sconsign.dblite .sconsign.tmp .sconf_temp config.log

• build (from the mixx build dir root)

  scons stdlib=libc++

  This should invoke a build with the following flags: asan=0 battery=0 buildtime=1 bulk=0 color=0 coreaudio=1 faad=0 ffmpeg=0 hid=1 hss1394=1 ipod=0 localecompare=0 macappstore=0 mad=0 mediafoundation=0 modplug=0 opengles=0 optimize=portable opus=0 perftools=0 perftools_profiler=0 profiling=0 qdebug=1 qt_sqlite_plugin=0 qtkeychain=0 shoutcast=1 test=False tsan=0 ubsan=0 vamp=1 verbose=1 vinylcontrol=1 wv=0

• launch mixxx from build dir

  ./mixxx --controllerDebug --resourcePath res

  or

  ./mixxx --developer --controllerDebug --resourcePath res

  or just

  ./mixxx --resourcePath res

  There is no need to build a bundle (scons bundle) after building from source, when testing local.

Hopefully this will allow you to build from source, reproduce the bug, and provide another backtrace to pin this down.

The symbols are included with the -g compiler switch

with optimize=native I get

-c -pipe -Wall -Wextra -g -O3 -ffast-math -funroll-loops -fomit-frame-pointer -march=native -pthread -DT_LINUX

with optimize=off I get -c -pipe -Wall -Wextra -g -pthread -Dx86_64 -DMIXXX_BUILD_DEBUG -DLINUX -DUNIX

Both version have the -g

I have found stripcode for MacOs though which removed the debug info: https://github.com/mixxxdj/mixxx/blob/d67bd7fe9913d046171944a12751f22754182a26/build/osx/OSConsX.py#L282

I do not know how it works.

This is a very serious bug. I am not comfortable releasing 2.1 until we at least get a good backtrace for this.

First of all: under Windows I could not reproduce the crash using the same midi controllers.

A CA file has been bootstrapped using certificates from the SystemRoots

the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local, because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

Why is QT4 command 'moc' not found?

That is what I have found on the web: You can either edit the file as proposed or set the Xcode build setting "Always Search User Paths" to YES.

As far as I've seen this setting is only available inside a Xcode project file which I don't have (I think?). I didn't find this setting in the Xcode preferences itself.

We have changed the build system to keep debugging symbols in the macOS builds. Max, can you try to reproduce this with the latest build from http://downloads.mixxx.org/builds/2.1/release/mixxx-2.1.0-rc1-2.1-release-macintel64-latest.dmg and attach a backtrace?

Now that I have access to a Mac, I tried hacking the Xone K2 mapping to map one of the encoders like a jog wheel with engine.scratchEnable/scratchDisable/scratchTick and cannot reproduce this with 2.1 RC build 6652. This is on a Mid 2011 MacBook Air running macOS 10.13.1.

@Max, that's an unfortunate, known bug in the Homebrew opus package. See the workaround in the Step 4 of the compilation instructions: https://mixxx.org/wiki/doku.php/compiling_on_os_x#compile_and_install

Basically define:
export CFLAGS="-I$HOMEBREW_PATH/include -I$HOMEBREW_PATH/include/opus"
export CXXFLAGS="-I$HOMEBREW_PATH/include -I$HOMEBREW_PATH/include/opus"
before running scons.

Sorry for the late answer, I was on Easter holidays.

@RJ Ryan: I already considered the workaround after my last post here and got another error (last state before giving it up):

At the moment I'm only able to reproduce the crash using the latest build if I don't use backtracing. Using backtracing I get the behavior that Mixxx doesn't do scratching while touching and moving the jog wheel for the first time (after starting Mixxx). This would also be the crash situation when I'm not using backtracing. On touching and moving the jog wheel for the second time I get the expected behavior (scratching).

How else can I submit you the necessary information to see what's happening here? What else can I do?

Again the actual procedure to generate the crash:

• Booting up MacOS
• Plugging in the MIDI controller
• Starting the terminal and enter "lldb /Applications/Mixxx.app/Contents/MacOS/mixxx"
• After that enter "run"
• Now in Mixxx go to the preferences and change the master sound output to the controller sound card channel 1-2 and headphones sound output to the controller sound card channel 3-4 (setting before is "Build-in sound".
• Apply the settings and close the preferences window.
• Load a track to Deck 1 and press play.
• Touch and move the jog wheel -> Track is just stopped/paused instead of scratching back and forth.
• Release jog wheel -> Track is playing again.
• Touch and move the jog wheel again -> Expected scratching is working.

Add: Procedure is described how I TRIED to generate the crash using backtracing. As said before I'm only able to reproduce the crash without using the terminal and the backtracing and starting Mixxx directly through the app shortcut.

Do you always install Qt via homebrew or have you ever installed it via Qt's installer packages?

Can you share the contents of /usr/local/bin ?

FWIW, I don't install Homebrew to /usr/local, I install it to
$HOME/.homebrew.

Oh! Your final include path (Building with CXXFLAGS: ...) includes -I/usr/local/opt/qt/include, which is going to use Homebrew's Qt5 install.

I wonder how that got on there? It isn't in your CFLAGS/CXXFLAGS, since you're setting those manually. Maybe our Qt scons code is setting that erroneously, but QTDIR is properly detected as /usr/local/Cellar/qt@4/4.8. 7_3.

Do you always install Qt via homebrew or have you ever installed it via Qt's installer packages?

I'd love to get to the bottom of this, I agree it's pretty troubling. It would be great to know the status of this bug in 2.1.x and 2.2.x.

Max, would you be willing to try to reproduce using Mixxx 2.1.4 and Mixxx 2.2.0 beta?

http://downloads.mixxx.org/mixxx-2.1.4/mixxx-2.1.4-osxintel.dmg http://downloads.mixxx.org/builds/2.2/release/mixxx-2.2.0-beta-2.2-release-macintel64-latest.dmg

No need to run using a debugger. If you get a crash, please just attach the macOS crash report found in ~/Library/Logs/DiagnosticReports/ or via the Console app. It would also help to have the mixxx.log from ~/Library/Application Support/Mixxx, but it's not crucial.

@Max, thanks so much for your testing so far. If you get the chance, it would be really helpful to see if the above two links (Mixxx 2.1.4 and 2.2.0 beta) crash. The mac crash report that they generate should have a useful backtrace in them, since those builds have debug symbols enabled.

Considering the lack of response and this hasn't been replicated with 2.2, I'm removing the 2.2.0 milestone.

Sorry for the late response. I finally found time to test it using Mixxx 2.1.4 and Mixxx 2.2.0 beta and tested it several times in different constellations.

I was NOT able to reproduce a crash anymore!

BUT still...after a fresh boot of MacOS, a fresh start of Mixxx and after reconfiguring the sound settings from internal sound to the controller's sound card...I wasn't able to do scratching on touching a jog wheel of a playing deck for the first time. The track only stops/pauses at the touched position. After releasing and touching the jog wheel again I can scratch normally. It's not that critical anymore but still annoying when you forget to touch the jog wheel once before you want to do some scratching.
