Yigit, do you have time to fix it?
reemission of the same liveData is racy

yea i'll take it.

Thanks for the detailed analysis. This may not be an issue anymore since we've started using Main.immediate there but I' not sure; I'll try to create a test case.

just emitting same live data reproduces the issue.
@Test
fun raceTest() {
val subLiveData = MutableLiveData(1)
val subject = liveData(testScope.coroutineContext) {
emitSource(subLiveData)
emitSource(subLiveData) //crashes
}
subject.addObserver().apply {
testScope.advanceUntilIdle()
}
}
@Test
fun raceTest() {
val subLiveData = MutableLiveData(1)
val subject = liveData(testScope.coroutineContext) {
emitSource(subLiveData)
emitSource(subLiveData) //crashes
}
subject.addObserver().apply {
testScope.advanceUntilIdle()
}
}

With 2.2.0-alpha04 (that use Main.immediate), the issue seems to be still there (I tested it by calling emitSource() twice, like your test case)
Description
Component used: Macrobenchmark Version used: AGP - v7.3.0 Profile Installer - v1.3.1 Devices/Android versions reproduced on: Vivo V2029, Android 12
I am trying to setup macrobenchmarking on my app which has multiple modules and multiple flavors and following the android developer guide. However, I am getting below error related to DROP_SHADER_CACHE even though I have added profileInstaller dependency on the target app.
com.example.macrobenchmark.ExampleStartupBenchmark > startup[V2029 - 12] FAILED java.lang.IllegalStateException: The DROP_SHADER_CACHE broadcast was not received. This most likely means that thehttps://developer.android.com/jetpack/androidx/releases/profileinstaller .
at androidx.benchmark.macro.MacrobenchmarkScope.dropShaderCache(MacrobenchmarkScope.kt:286)
androidx.profileinstallerlibrary used by the target apk is old. Please use1.3.0-alpha02or newer. For more information refer to the release notes atI am using Android Gradle Plugin v7.3.0 and Profile Installer v1.3.1
Below error comes while running benchmark tests.
I have observed that APP installed as part of the above process crashes on launch. This might be the reason of above error.
