3.0.2 typing incompatible with 3.0.1 #13491

jrudolph · 2021-09-09T08:15:57Z

Compiler version

Our ongoing effort to port parboiled2 (and maybe more importantly akka-http and depending projects) to Scala 3, is hindered by the fact that code that compiled with 3.0.1, does not type correctly any more with 3.0.2.

Admittedly, the typing code is sophisticated, so we didn't expect that it would work unchanged from Scala 2 before. We rewrote some of the heavy implicit machinery using type matches which seemed to work somewhat with 3.0.1 (aside from some typing errors, stack overflows in the typer, and typing termination problems that we ignored or worked around for now).

Reproducer

See sirthias/parboiled2#280, and use Scala 3.0.2 instead.

Output

Lots of type errors.

Expectation

Typing correctly.

I've tried to investigate that and indeed code that was compiling in 3.0.1 is failing now.

The error is:

The offending snippet:

rule {

    decoder(input.sliceCharArray(start, cursor)) match {
      case null  => MISMATCH

    }

}

It involves HLists and match types. It will be really hard to tell if this is indeed a regression or the compiler erroneously was accepting the code that shouldn't compile, without a smaller self-contained example.

@jrudolph First step here would be to find the first nightly where this is failing via bisection, to use a nightly simply set scalaVersion to a version number from https://repo1.maven.org/maven2/org/scala-lang/scala3-compiler_3/ (the nightlies of 3.0.2 all start with 3.0.2-RC1-bin-)

It happened in this range: fb6b453...ecbe3d2. From the description, most likely it might be this change: ~~fb6b453...ecbe3d2~~ a023600

jrudolph · 2021-09-09T13:15:10Z

Here's a relatively simple example:

      "Map[String, T]" - new TestParser1[Int] {
        val colors = Map("red" -> 1, "green" -> 2, "blue" -> 3)

        // does not work
		//def targetRule = rule(colors ~ EOI)    
		
        // works
        val colorRule = rule(colors)
        def targetRule = rule(colorRule ~ EOI)

        "red" must beMatchedWith(1)
        "green" must beMatchedWith(2)
        "blue" must beMatchedWith(3)
        "black" must beMismatched
      }

One problem with the error messages is that not all place holder are explained, so it's hard to see what might be wrong.

Can you turn this example into something self-contained?

jrudolph · 2021-09-10T09:30:02Z

Oops, I meant a023600 which seems to be the only significant typing change in that time span.

The code does compile if we revert the fix to TypeOps#simplify in a023600 but the previous behavior was unsound, so either the code is broken or the match type reduction logic does not handle skolems properly. The error we get is:

   |  failed since selector  ?3.Out
   |  does not match  case HNil => HNil
   |  and cannot be shown to be disjoint from it either.

Replacing i" by ex" in the errors printed in MatchTypeTrace#explainEntry, we can get more information:

where:    ?3 is an unknown value of type HListable[Int]{Out = HListable.HL0[Int]}

And if I'm reading the definition of HL0 correctly, then ?3.Out should reduce to Int :: HNil which the compiler should be able to figure out is disjoint from HNil, so this looks like a bug in the match type reduction logic.

jrudolph · 2021-09-13T12:29:15Z

Great, thanks for the analysis, that sounds reasonable.

dwijnand · 2021-09-13T13:05:21Z

but the previous behavior was unsound, so either the code is broken

The use of @uncheckedVariance is perhaps worth investigating too.

dwijnand · 2021-09-13T13:13:45Z

And if I'm reading the definition of HL0 correctly, then ?3.Out should reduce to Int :: HNil which the compiler should be able to figure out is disjoint from HNil, so this looks like a bug in the match type reduction logic.

I wonder if the fact that HListable isn't sealed is relevant. Int :: HNil is probably an upper bound, but :: is also final so I'm not sure why that wouldn't still compute as disjoint from the sealed HNil.

This somehow fixed itself in recent nightlies, I've verified that it also fixes the original problem in the parboiled2 scala3 branch by setting scalaVersion := "3.1.1-RC1-bin-20210922-b13f37a-NIGHTLY" and fixing the pattern match on scalacOptions in the build to work with 3.1

Fix #13491: Add regression test

Perhaps #13483

Nope, Olivier bisected it in #13585 (comment), it was fixed in #13253

Thanks for the fix(es). Seems the latest nightly works as well as 3.0.1 worked before!
