I recently upgraded to IntelliJ 2019.3 and to Kotlin 1.3.61, and I'm starting to see a ton of "Inappropriate blocking method call" inspections. They mostly seem to be inside suspend functions where they call other suspend functions I wrote, so they seem like they may be spurious. Does anyone have any ideas about how to learn more about why these inspections are showing up, to either report a bug or to fix my code if it is in fact bad?

Those should only be marked on blocking methods such as Lock, any I/O calls, or things that throw InterruptedException. The fix is to ensure you are running those methods under Dispatchers.IO, but if they're suspend functions it sounds like a bug

[David Glasser]

Right, the highlighted function call in question is a function I wrote, not some sort of built in/library function

[David Glasser]

so I don't get if it's trying to tell me that the highlighted call somehow actually is blocking even though it's a suspend function (but there are no inspections showing up inside its own body), or what

[octylFractal]

yea, probably a bug. I would Invalidate Caches and restart IntelliJ, see if it persists

[David Glasser]

heh, i guess i don't need to get any work done for the next half hour 🙂

[octylFractal]

if so, check for an existing bug and file if none found

[David Glasser]

one thing that is odd is that when i searched the YT for the error message, all the references came back saying "inappropriate thread-blocking method call" but the inspection I'm seeing doesn't have thread- in it

Hmm maybe this is related to having an @Throws on my method?

I noticed that it mostly targets methods that throws IOException, as those methods will always perform IO in some way due to Java having checked exceptions.
