Línea de trabajo

Comienza con src/Sentry.Unity/Il2CppEventProcessor.cs y src/Sentry.Unity/Integrations/UnityApplicationLoggingIntegration.cs; después, compara el comportamiento de los stacktraces de excepciones de Unity 6 descrito aquí con el flujo de procesamiento existente. La tarea estará terminada cuando los stacktraces de Unity 6 conserven la información del método, el archivo y la línea, mientras el SDK evita el procesamiento innecesario de IL2CPP cuando los nuevos datos estén disponibles.

Descripción

Errors Improvement Unity

Context

To provide line numbers we're added the IL2CppEventProcessor. The main responsibility of this processor is to call into the IL2CPP backend, get the native stacktrace and match it with the managed one and fix instruction addresses. With those Sentry is able to serverside symbolicate the issue.

Unity 6

What's New

Unity 6 introduced a new option to the IL2CPP configuration and exception can now include method name, file name, and line number.

Triggering a NullReferenceException and logging is via exception.toString() results in the following logs

System.NullReferenceException: Object reference not set to an instance of an object.

What does this enable
Line numbers for Debug.LogError

Events captured via Debug.LogError automatically contain line numbers as these are parsed from the stringified stacktrace in the ApplicationLoggingIntegration.

Line numbers for unhandled exceptions

In Unity 6 and newer, with this option enabled, the SDK no longer needs to go register the IL2CPP processor to calling into the IL2CPP backend. This also means, stacktraces and linenumbers work without debug symbol upload.
Note, that this most likely comes at a cost to performance.

Notes

It is not required to opt-in having stacktraces in the player settings. The exception itself has the proper stacktrace with line numbers.
