Devices/Android versions reproduced on: We've seen it on 4.4.4 and 4.4.2

We haven't been able to reproduce this ourselves, but we're seeing it show up in our tracking. There's a StackOverflowError caused somewhere inside WorkManager. Here's the stack trace we get:

Re-factor how errors are dismissed when query is re-written

This CL changes how we handle errors/warnings if query is
re-written.
There was a bug in expandProjection where we would report warnings
for things that Room already fixes automatically (

b/140759491

).
The solution to that problem (I7659002e5e0d1ef60fc1af2a625c0c36da0664d8)
solved it by deferring validating of columns until after re-write
decision is made. Unfortunately, this required changing PojoRowAdapter
to have a dummy mapping until it is validating, make it hard to use
as it does have a non-null mapping which is not useful.

This CL partially reverts that change and instead rely on the log
deferring logic we have in Context. This way, we don't need to break
the stability of PojoRowAdapter while still having the ability to
drop warnings that room fixes. This will also play nicer when we
have different query re-writing options that can use more information
about the query results.

The manual flushing is called when the user takes a particular UX action or closes a fragment that has attached to the object generator. In typical usage, this might happen a couple times in the first few minutes, but then would be unlikely to be called again.

Here is the chain:

val timer = Observable.interval(5, TimeUnit.MINUTES, scheduler)
eventSubject
.buffer( // Flush buffer on timer, or when signal is called
Observable.merge(
timer.map { Unit }, // We don't care what types are emitted, we just care that a value came out
flushObservable.map { Unit }
).map { // Debug log }
)
.filter {
it.isNotEmpty()
}
.observeOn(scheduler)
.subscribe(
{ events ->
enqueueWork(events)
},
{ // Log error })

Thanks for addressing that so quickly. Do you know approximately how long it will take for it to make it into a release? And is it at all possible that this will be incorporated into the non-Android-x version of WorkManager? It's a little frustrating that two days after 1.0.0 was released, it was announced that there would be no more development on the non-Android-x version.

su...@google.com <su...@google.com> #9Mar 28, 2019 09:11PM

This will probably be available next week, and so far the plan is to port it to the 1.x branch as well.

That being said, please be aware that all active Jetpack and Support Library development is happening in the AndroidX branches, so I would highly recommend switching your app when you get a chance. Thanks!

Thanks for the info. We're definitely planning on moving to AndroidX, but until we do, I appreciate that you're porting fixes to the old version.
