Crash Stacks / Line Numbers for Xamarin Apps #165

Open kensykora opened 5 years ago

kensykora commented 5 years ago

Crashes and errors that are collected today are really nice, but they aren't including line numbers. So when I see a crash with a stacktrace like this, it's really difficult to pinpoint exactly where the exception occurred. At best I can make an educated guess. Especially tricky when it's a very low frequency crash that we haven't been able to reproduce yet

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

App.MyApp.Services.BluetoothService+<>c.<ReadInitializationData>b__48_0 (App.MyApp.Member.JournalEntryModel x)
System.Linq.Enumerable.Max[TSource,TResult] (System.Collections.Generic.IEnumerable`1[T] source, System.Func`2[T,TResult] selector)
App.MyApp.Services.BluetoothService+<ReadInitializationData>d__48.MoveNext ()
System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess (System.Threading.Tasks.Task task)
System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification (System.Threading.Tasks.Task task)
System.Runtime.CompilerServices.TaskAwaiter`1[TResult].GetResult ()
App.MyApp.Services.BluetoothService+<>c__DisplayClass34_0+<<InitializePuck>b__0>d.MoveNext ()

I can't think of any alternative way to achieve this behavior. We have considered shipping log data with the crashes to supplement but that only goes so far.

For those on Xamarin (https://github.com/getsentry/sentry-xamarin) MAUI (https://github.com/getsentry/sentry-dotnet) Or just native Android/iOS apps with .NET, you can get line numbers in .NET stack traces with Sentry:

https://docs.sentry.io/platforms/dotnet/guides/maui/#overview-of-the-features

You need to upload PDBs. It's automatic if you configure the org-slug/auth token via msbuild or env vars, or CLI args: https://docs.sentry.io/platforms/dotnet/guides/maui/configuration/msbuild/

Also support native crashes on both iOS and Android. Code is here: https://github.com/getsentry/sentry-dotnet

I use it on this project: https://github.com/getsentry/symbol-collector

These are release builds in production:

For anybody still hoping this gets fixed, App Center is officially being retired.

And Sentry continues to support line numbers for all types of .NET app including mobile:
