@romtsn This should target 6.x.x

@romtsn This should target 6.x.x

Why?

marandaneto · Apr 6, 2022

@romtsn This should target 6.x.x

Why?

Hub interface is a public API and it has changed.

@marandaneto mm, but only methods marked as Internal have changed. Only if we care about ABI, then it makes sense.

Indeed, but I'd rather point to v6 to speed up this major release, by that I mean more people working on the new code base and testing out all the changes.
Unless @bruno-garcia says otherwise.

sounds good, have no problem with targeting 6.x.x actually!

@marandaneto @philipphofmann @adinauer this is ready for review PTAL

Overall the PR looks great. Thanks for all the effort. Maybe I missed it, but I'm not sure if the code handles the following scenario:

Scenario: Ongoing UI event transaction
   Given an ongoing UI event transaction
   When the SDK creates a new screen load transaction
   Then the SDK finishes the previous transactions
   And removes it from the scope
   And sets the status to canceled
   And waits for its children to finish

    }
+
+    @Test
+    fun `when initialized without idleTimeout, does not schedule finish timer`() {


m: Can we also add a test for when the idle timeout expires, but the transaction has still an unfinished child. I think we should then wait for the child to finish.

But we said we cancel the timer when a new child is added and reset it when the last child is finished, so there's technically no idle timeout while there's an ongoing child span.

Even though, this has been missing in my code, so I'll update that, thanks for the point.

Yes, makes sense. Thanks for the clarification.

Yeah, this is done here ->

sentry-java/sentry-android-core/src/main/java/io/sentry/android/core/internal/gestures/SentryGestureListener.java

Lines 265 to 276 in f67519e

    
           void stopTracing(final @NotNull SpanStatus status) { 
        
             if (activeTransaction != null) { 
        
               activeTransaction.finish(status); 
        
             } 
        
             hub.configureScope( 
        
                 scope -> { 
        
                   clearScope(scope); 
        
                 }); 
        
             activeTransaction = null; 
        
             activeView.clear(); 
        
             activeEventType = null; 
        
           }

With the only difference that we do this when the current screen goes inactive (onPause). This makes sense for us, because we use android's WindowCallback, which will get detached as soon as the activity/screen goes inactive, therefore it wouldn't make sense for us to wait until the new screen transaction, but rather finish it here.
