Crash on plugin removal or exiting DAW #108

Open mister-benjamin opened 4 years ago

mister-benjamin commented 4 years ago

I can successfully insert and use Fabfilter ProQ 3 on a channel strip of Harrison Mixbus. But when I want to remove the plugin or exit Mixbus, the Airwave wine process crashes and freezes the DAW.

I used AirwaveManager 1.3.3 installed from the dpkg provided on this site. I am on Debian 10 amd64. Wine version is 4.0 64-bit from the official Debian repo. My plugin host is Harrison Mixbus 32C 6.0.

Here's the backtrace: backtrace.txt

After disabling 2D graphics rendering in Mixbus, the backtrace shows some more human readable information: backtrace2.txt

If it happens when you open multiple airwave plugins, I would suggest to try my branch to see if you have still an issue: https://github.com/asb2m10/airwave

The problem is related to the signal handler and I've removed it since it is not required anymore with Renoise.

@asb2m10 Hi, what wine version do you use? I'm unable to run any plugin with recent Wine 5.2

Thanks for bringing your fork to my attention. I compiled it in order to see if it solves my problem. Unfortunately using the manual build failed to successfully scan my plugin. I am now using LinVST which seems to work for me, so I didn't try to investigate this any further.

I am using Wine 4.0 (Debian 4.0-2).

I'm using Wine 5.2. I've tested Pro-Q 3 on my side and it worked fine.

If you build it in debug with my branch, there should be more details on the stacktrace when the plugin crash.

Run with debug build. Can it help?

The plugin crashed on first call... usually this means a wine build issue or not.

  1. Put the plugin log level in flood mode (with the airwave-manager). Then open the plugin while leaving the airwave-manager open so you can see the logs from airwave-manager.

  2. Wine could log the issue but there is almost no way to see it. To see this change the file /opt/airwave/bin/airwave-host-64.exe at the end from

# and try to start the app
exec "$WINELOADER" "$apppath" "$@"

to

export WINEDEBUG=fixme-all,warn,trace+thread

# and try to start the app
exec "$WINELOADER" "$apppath" "$@" >> /tmp/airwave.log 2>&1

I hope that /tmp/airwave.log will have a better description on what is going on...

Sorry for long no answering, but I've stuck with building recent Carla. When I resolve that issue - I'll post the results.

asb2m10 commented 4 years ago

No problem. If you pull from my latest branch, I've added a tester that logs wine logs on the command line.

$ export WINEDEBUG=fixme-all,warn+all
$ /opt/airwave/bin/airwave-tester '~/.vst/DUNE 3.so'
