I’m not able to get the k2-performance-metrics notebook to run successfully. As far as I can tell, the gradle-profiler runs are successfully running but the notebook itself falls over.

[Zac Sweers]

my repro case is pointing it at https://github.com/zacsweers/catchup with build task :app:assembleDebug

[Zac Sweers]

it seems almost like it’s running with some incompatible version of kotlin? The error messages look like compiler errors

Tried on a second computer and got the same issue. It doesn't seem like this notebook works as it is on main

reports I'm testing on

I was able to get this working, it looks like the failures happen if there’s a non-zero exit code from one of the profiler runs, and I had missed that in the execution logs

[Zac Sweers]

err, well I say that but I get similar errors again running on a different project where both profiles are successful

this time testing https://github.com/slackhq/circuit

I notice sometimes the file gets modified, then when I revert it it suddenly works 🤔

[Zac Sweers]

ugh, nevermind. It’s just showing template data when I revert. Fails again when I rerun

[Zac Sweers]

same when I test on the catchup repo as well, also with both profiler runs successful

I’ve checked the logs and tried to reproduce the problem. It seems that for some reason Kotlin daemon is disabled in the setup (during benchmark run)
java.lang.RuntimeException: Could not connect to Kotlin compile daemon
It both causes strange results and inability to make the visualization - since only Kotlin daemon reports metrics in proper format.

Yes, thank you.
I have noticed that it was out-of-process compilation:

Build attributes:
  REBUILD_REASON: Out of process execution

But it is unclear why it behave this way every time
