Scala 3.2.0-RC2 Open Community Build regressions tracker

[WojciechMazur]

Each table contains a list of projects that failed to compile with Scala 3.2.0-RC2, but was successfully built with the given previous version.
A summary is based only on final and released candidate versions of Scala 3.
Information about the last Scala version used for the last successful build might not always be correct, due to lack of data (lack of build for that project with given Scala version)

• Version - version of project being built, single version if both current and last successful build version of project are equal, otherwise 'LastSuccessfullProjectVersion -> CurrentProjectVersion>'
• Build URL - link to the Open Community Build, containing logs and details of the failed project
• Reproducer issue - link to the reproducer issue to be filled in

Open community build might have applied -source:X-migration flag if it is detected it could possibly fix the build.
Summary only contains projects that failed when compiling source or test files of at least 1 sub-project.

All tested projects: 818
Open Community build run: Build #17 - 3.2.0-RC2-all-projects

Notes for issue reproducers:
To reproduce builds locally you can use:

scala-cli run https://raw.githubusercontent.com/VirtusLab/community-build3/master/cli/scb-cli.scala -- reproduce --locally BUILD_ID

BUILD ID can be found in the BUILD_URL columns (eg. Open CB #BUILD_ID)
Helpful options for reproducer scripts:

• --scalaVersion VERSION run build with the selected version of Scala (to check if the problem existed in given release)
• --withUpstream - build also all upstream dependencies of failing project
• --locally - checkout and build the project locally, without this flag it would try to start a minikube cluster to make the reproduction environment exactly the same as in the Open Community Build run (eg. to compile with the same version of the JDK)

The build failures of ohze/akka-guice, ohze/couchbase-scala, and ohze/sd-util are all due to the use of the sbt plugin "com.sandinh" % "sd-devops-oss". That plugin checks the value of CrossVersion.scalaApiVersion(scalaVersion):

https://github.com/ohze/sbt-devops/blob/771fbf9283d687e2fe68e5918adec23097cb3891/sd/src/main/scala/com/sandinh/sbtsd/SdPlugin.scala#L150

which has this behavior:

CrossVersion.scalaApiVersion("3.1.0")       // Some((3,1))
CrossVersion.scalaApiVersion("3.1.3")       // Some((3,1))
CrossVersion.scalaApiVersion("3.1.0-RC1")   // None
CrossVersion.scalaApiVersion("3.1.3-RC1")   // Some((3,1))
CrossVersion.scalaApiVersion("3.2.0")       // Some((3,2))
CrossVersion.scalaApiVersion("3.2.0-RC2")   // None      <---- this is our failing case
CrossVersion.scalaApiVersion("3.2.1-RC2")   // Some((3,2))

I'm not sure if this scalaApiVersion method is intended to be used with Scala 3 versioning (all the test cases are for Scala 2), but it seems the issue here is either with the plugin or sbt.

Btw, I'm looking into my own project on that list. I don't think it's a regression, even the current main doesn't seem to be compiling locally even though CI is green. So something weird going on.

[som-snytt]

@armanbilge technically, that is called a weird regression.

[griggt]

Some of the other build failures are not regressions per se, but expected based on changes from 3.1 to 3.2.

Examples:

• indoorvivants/subatomic and mvv/typine apparently use non-local returns, which are no longer supported
• shiftleftsecurity/codepropertygraph has pattern binding narrowing (this now warns and it appears they are using fatal warnings)
• zengularity/benji uses refutable extractors (these now warn, and fatal warnings seem to be enabled)
• gchudnov/swearwolf triggers a new deprecation warning ':' after symbolic operator is deprecated; use backticks around operator instead and appears to be using fatal warnings

[armanbilge]

I offer CI evidence that my project is fine on 3.2.0-RC2.
https://github.com/armanbilge/saslprep/runs/7294875650?check_suite_focus=true

I don't know what's magic about CI. Seems to go badly wrong basically everywhere else, not just Scala 3 but Scala 2 as well.

[griggt]

Here's a reproducer for the tinkoff/phobos failure:

import scala.quoted.*

class ProductTypeField(using val quotes: Quotes)(val name: String)

def foo(using Quotes): ProductTypeField = ProductTypeField()("")

-- Error: ptf.scala:5:58 -------------------------------------------------------
5 |def foo(using Quotes): ProductTypeField = ProductTypeField()("")
  |                                          ^^^^^^^^^^^^^^^^^^
  |missing argument for parameter name of constructor ProductTypeField in class ProductTypeField: (name: String): ProductTypeField

However if I understand correctly this is caused by an intentional source breaking change in #14840?

[griggt]

Btw, I'm looking into my own project [saslprep] on that list. I don't think it's a regression, even the current main doesn't seem to be compiling locally even though CI is green. So something weird going on.

I cloned it and built and tested locally on 3.2.0-RC2 and it was fine, so 🤷

[WojciechMazur]

@griggt great hob. The failure in shiftleftsecurity/codepropertygraph in theory should be handled as we do apply -source:3.2-migration flag if logs show us it could fix the build, the problem was caused by the fact of combination -Xfatal-warnings or -Wconf:e:any flag which do elevate warning about possible rewrite, into an error (#15589)
