should we hold off on
1.4.30-1.0.0-alpha02
?

Ting-Yuan Huang

02/10/2021, 1:30 AM
well, we planned to announce it tomorrow 😛
z

Zac Sweers

02/10/2021, 1:30 AM
haha ok just checking, wasn't sure since it came right after alpha01 and figured you might be double checking something
t

Ting-Yuan Huang

02/10/2021, 1:32 AM
Yeah, we found something funky after the alpha01 while testing and therefore need to pull it down. The alpha02 should be in a good shape but please allow us to give it more tests.
z

Zac Sweers

02/10/2021, 2:11 AM
I just tested it out and seeing huge memory usage spikes. It OOMs
kotlin-compile-testing
tests

Ting-Yuan Huang

02/10/2021, 2:13 AM
Thanks for trying it out. Let me take a look to see if we need alpha03 😢

One thing I could think of from the commit is you didn’t check if the processor has been invoked. With multiple round, if you have some files generated every round regardless of the input from annotated symbols, then multiple round will continue retrying for a fix point which never comes
t

Ting-Yuan Huang

02/10/2021, 2:44 AM
I can repro. From the log, there are ~500 rounds for each of the failing tests.
z

Zac Sweers

02/10/2021, 2:53 AM
That could do it, I don't think kotlin-compile-testing is aware of multiple rounds
Maybe this is me learning I should contribute it 😅

Thanks again for trying it out. We'll make a note of this API change in the release.

hmm we did have this OOM when updating kotlin to 1.4.30 in androidX infra
but it went away after ksp also updated to 1.4.30
z

Zac Sweers

02/11/2021, 8:20 AM
yeah I'm not actually sure where kotlin-compile-testing is doing anything wrong 🤔
I think I've figured it out, it has some tests that always generate files regardless of inputs, so it gets into a loop
even with this though, I see a stackoverflow crash coming from kotlinc analysis handling in my own tests here. Not totally sure what I'm looking at though, would be curious for thoughts https://github.com/ZacSweers/auto-service-ksp/pull/10#issuecomment-777281721
t

Ting-Yuan Huang

02/11/2021, 7:05 PM
This looks like many rounds. @Jiaxiang?

Zac Sweers

02/11/2021, 7:07 PM
I can't spot anything obviously wrong with what my plugin does though, unless it's something related to the fact that it only generates resources?
t

Ting-Yuan Huang

02/11/2021, 7:12 PM
We'll investigate. Could be some termination problem. Repro is checking out the branch and
./gradlew :ksp:test
right?
z

Zac Sweers

02/11/2021, 7:13 PM
just
./gradlew :processor:test
, no
:ksp

Thanks, let us try

Jiaxiang

02/11/2021, 7:29 PM
it looks that
generateConfigFiles()
is called every round?
z

Zac Sweers

02/11/2021, 7:40 PM
yes but it should only generate new files
unless....
wait I have an idea
j

Jiaxiang

02/11/2021, 7:42 PM
it looks that a clear() on the
providers
might be a fix

Zac Sweers

02/11/2021, 7:42 PM
yup that's what I'm thinking
👍 1
yup that did it
sorry for the fire drill 😅
j

Jiaxiang

02/11/2021, 7:44 PM
good to hear! Yeah I do think the multiple round infinite loop seems to be quite confusing and I might want to emphasis it in the next release note..
z

Zac Sweers

02/11/2021, 7:45 PM
would it be helpful to maybe check for "re-generated" files? I.e. detect when something is in a loop
j

Jiaxiang

02/11/2021, 7:45 PM
it is doable, I can simply add a check for file path in that case
z

Zac Sweers

02/11/2021, 7:46 PM
👍
j

Jiaxiang

02/11/2021, 7:47 PM
but on the other hand, a processor should not generate to the same file in different rounds (it is not easy for ksp to check if the contents are identical), does it make sense for
CodeGenerator
to throw exceptions when user tries to create a new files that has been created in previous rounds?
z

Zac Sweers

02/11/2021, 8:52 PM
I think so, it would have undefined behavior at best unless the goal is to allow later overwrites
