Describe the bug

On a project I work on regularly, I've been noticing that metals seems to intermittently crash.

In the metals log file I see:

SEVERE: A severe compiler error occurred, full details of the error can be found in the error report /Users/medmison/mdm/worktrees/mdu/WH-77181/.metals/.reports/metals-full/2024-10-02/r_compiler-error_(wh-77
181)_14-16-22-682.md

The contents of this file (apologies in advance as it's quite long):

I'm not really sure how to further troubleshoot this (or if this is even an issue with Metals or the compiler itself?). Happy to dig deeper but would need a bit of help figuring out where to start.

Thanks for reporting! Does it only happen in that specific file? Or does it break other files as well?

@tgodzik I've noticed with at least three different files, two of which are source files in the project.

Update: Something strange I've noticed is that different errors are thrown when Metals crashes. For instance, today Metals crashed, with a SEVERE: A severe compiler error occurred, full details of the error can be found .... in the logs, and the short summary is:

java.lang.NullPointerException: Cannot invoke "scala.reflect.internal.Symbols$Symbol.isImplicit()" because the return value of "scala.reflect.internal.Trees$Tree.symbol()" is null

and the stack trace is:

The file is different, too.

According to the summaries of this error, it would seem that the errors are completely different but I do find it a strange coincidence that the same code base would trigger both of these errors.

If you do think that this is a separate potential issue, let me know and I can create a separate issue from this one.

I think the other error was already fixed in #6825

@tgodzik Ah, I see. I'm sorry I missed that.

In terms of the original issue reported, I've started to poke around a little bit, and, in short, it looks like the failure is occurring when we "get" the semanticDB text document that, somewhere?, includes a Type that is a g.TypeBounds(glo, ghi) where glo, or the lower type bound, is Any. The error is being thrown where the SemanticDB type is computed from the scala.reflect Type. It seems absurd that a lower bound would be Any but it's not at all clear to me where things are going wrong.

Any tips in how to further troubleshoot this? Next, I was going to try to add some debug information to see if I can at least track down the specific file where this error is being raised.

There are possibly couple of ways to go about this:

  • fix the issue in semanticdb scalameta/scalameta to handle that type
  • figure out if the compiler is compiling something wrong or maybe something doesn't work with the presentation compiler
  • catch the error and just return None for semanticdb as for normal files it's only a fallback. For dependency sources we could use the presentation compiler directly from the ReferenceProvider, which should be more reliable

Last option would be lowest effort probably. First one a bit more complicated since we would need to delve into semanticdb, which is not the easiest code. Second one I don't even know how to go about.

@tgodzik I see. Regarding the last option, this is the call site in which the exception is being thrown. The exception being thrown is happening here.

If we were to take this approach, how fine-grained would we want to be in the errors we "catch"? The error being raised is a RuntimeException but we could pattern match on the text "s"unsupported type $gother: ${g.showRaw(gother)}" which, admitingly, feels quite hacky.
