Symbolicate crash report for libmonosgen-2.0.dylib not working? #3752

Open VincentDondain opened 6 years ago

VincentDondain commented 6 years ago

How do I get symbolicated crash reports for libmonosgen-2.0.dylib and libxamarin-debug.dylib?

Maybe I'm doing something wrong but I assumed that with the app and the attached dSYM, the crash log would be symbolicated fully (including libmonosgen). Am I missing something?

Tried to run /Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash -v to force the resymbolization (in case Xcode didn't do it completely).

Maybe @rolfbjarne knows :)

@rolfbjarne so if I manually copy /Library/Frameworks/Xamarin.iOS.framework/Versions/Current/SDKs/Xamarin.WatchOS.sdk/usr/lib/libmonosgen-2.0.dylib.dSYM next to my crash, app and app.dSYM I can symbolicate libmonosgen-2.0.dylib.

Xcode doesn't do it automatically though and also it's missing the SpeedySlothWatchAppExtension symbols and libxamarin-debug.

rolfbjarne commented 6 years ago

mdimport /Library/Frameworks/Xamarin.iOS.framework/Versions/Current would probably also work, and make Xcode find the dSYM automatically. I believe Spotlight will eventually index it, but you probably tried to symbolicate before it had finished.

libxamarin*.dylib currently doesn't have dSYMs, so that's kind of expected (we should probably fix it though).

I'm not sure what's up with the symbols for SpeedySlothWatchAppExtension, that should work.

VincentDondain commented 6 years ago

@rolfbjarne mdimport /Library/Frameworks/Xamarin.iOS.framework/Versions/Current seems to have helped Xcode symbolicate automatically. Wonder if we should force run that ourselves though? Note that Mykyta's crash isn't symbolicated either: https://github.com/xamarin/xamarin-macios/issues/3707. So most likely our customers run into the same issue and don't give us properly symbolicated crashes.
