Date: 2012-09-27T19:27:27Z
Status: Confirmed
Importance: Critical
Launchpad Issue: lp1057715

this is for mixxx 1.11.0 beta

If I have my quneo plugged in and successfully controlling mixxx, then accidentally unplug the quneo, Mixxx will freeze and seg fault when it tries to send midi output to the quneo.

this is on linux debian, 64bit AMD processor, Xonar DX audio card

this segfault occurs very regularly with the quneo, although i have no other hardware with which to test it.

Hi Daniel -- could you get a backtrace for the segfault?

Mixxx indeed does not like it when you unplug USB devices.

Thanks!

OK -- some good news. This is not a segfault but an unceremonious exit(-1) on the part of PortMidi. Basically whenever PortMIDI encounters an error while writing a short message or doing other things it exit(-1)'s if it was compiled with the PM_CHECK_ERRORS pre-processor flag.

The bad news is that if you got the PortMIDI binary from a popular software repository (e.g. Ubuntu or Debian packages) then we have to get in contact with the maintainer and get them to build it without that symbol defined.

Daniel -- how / where do you get your PortMIDI binaries from? Did you compile yourself or install from a package?

We should double check we do not compile PortMIDI with this flag turned on for the Windows / Mac builders. Sean -- can you double-check on Windows and I will check the OS X builder?

I used the command:

sudo aptitude install portaudio19-dev

Sorry for the long wait in response!

I'm about to install mixxx on a new debian environment - I'll let you know which package I use, and recreate the problem to see if it's still there.

After going through the above procedure on the fresh environment, the same -1 exit code occurred. I for sure installed the portaudio19-dev package.

Good news -- the PortMIDI Debian maintainer is looking at fixing this.
