Re: 2.8.0.RC1 Compiler stack trace with ScalaTest

The parameter name is '-no-specialization'. I believe I already have a fix for this one, waiting to build scalatest and the test suite before I commit. There may be delays though, with the first day of Scala Days.

Hi Ismael,

Unfortunately, I'm getting this:

BUILD FAILED
/Users/bv/nobkp/delus/stForScala2.8h/build.xml:158: Parameter
'-Xnospecialize' is not recognised by Scalac.

I can't find documentation of the parameter. I tried a few different
spellings, and double checked I was using 2.8.0.RC1, just to make sure
I was looking at the right thing.

I had just copied the compiler switch from a different mailing list
thread without actually trying it myself. :) I see that Iulian has
already given you the right one though (and even better, an actual fix
is on the way).

Best,
Ismael

Hi Iulian,

I hit this problem building Scalaz with specialization.

Hi Ismael,

I had tried a few different spellings, but didn't guess that one. That
worked! I got past the compiler stack trace and was able to compile
ScalaTest itself under RC1. Now trying to compile its tests.

Thanks.

Hi Ismael,

The -no-specialization flag did the trick. Everything compiles and I
deployed a snapshot. I'd guess everyone is seeing the same problem,
but I'll file a ticket anyway for completeness.

I just committed a fix for this and I can compile and run scalatest. It is a fundamental change in the way specialized overrides are treated, so it's likely to fix a lot of bugs/crashes. However, I have a number of scalatest tests that fail, and I am wondering if the branch I checked out (trunk-for-scala-2.8h) is actually up to date. I get the same failures with and without specialization, and most of them have to do with either class names (expecting WrappedArray instead of a native Java array -- a change that predates specialization) or order of keys in Maps. 
It would be great if someone could help here and tell me if these failures are due to specialization or simply out-of-date code.
Thanks!iulian

Hi Iulian,

Yes, that's the latest branch. I have yet to finish fixing those
tests, which broke when arrays were changed in 2.8.
