| | | | | | | | | | This commit fixes test cases mentioned in comment 03/Apr/12 to SI-4540. Methods are fixed in leaf classes RichDouble|RichFloat|RichLong. Their superclasses are not modified. File is-valid-num.scala contains commented tests of isValidLong|isValidFloat|isValidLong, but they are not added anywhere now.

* | | SI-4134: abstract override crasher if lacking super implSom Snytt2012-04-062-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The example from the ticket is committed as a neg test. The problem is that a super.m on an abstract override member m has no concrete implementation, that is, the trait T is not mixed in after a class C with a concrete m. The error is noticed at phase mixin when the super accessor is added to the concrete mixer. (Pun alert?) When super.m is rebound, no concrete matching symbol is found up the linearization. Previously, it was asserted that such a symbol should be found, but since this is our first opportunity to detect that there is none, an error should be emitted instead. The new message is of the form: Member method f of mixin trait T2 is missing a concrete super implementation. Additionally, a couple of flag tests were changed to use isAbstractOverride.
* | | Make NumericRange# O(1) instead of O(n).Simon Ochsenreither2012-04-062-17/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It makes me a bit nervous that NumericRange[Int] will get different wrong values in overflow situations compared to Range due to the missing toLong though. It could probably need some investigation if reordering the operations can rule out wrong values, e. g. only fail when the fold also fails. Apart from that, it might make sense to just throw an exception if an overflow happens instead of silent overflow.

| | | | | | | | | | | | | | Don't let OverloadedTypes reach the backend. When you want a method from a particular symbol, avoid getMember, which may inflict upon you an OverloadedType if an inherited member has the same name. Instead, use the (just now appearing) definitions.getDecl.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The source of many bugs over the years is that the first is represented as a TypeRef and the second a SingleType. Over a great period of time I figured out how to shield us from the more obvious bug manifestations, but a recent comment by adriaan jarred me into realizing that we can fix it at the source. This commit changes <:< and =:= to recognize when those two representations are being compared and to treat them as equivalent regardless of which is on the left. The reason I don't quash one representation entirely is that a fair bit of code depends on singleton types having an underlying type which is not the same, and regardless of that it would entail more changes and more risk. The change allows removing the type inference conditions which worried about this, and also fixes SI-4910. scala> val t1 = typeRef(ScalaPackageClass.thisType, NoneModule.moduleClass, Nil) t1: $r.intp.global.Type = None.type scala> val t2 = t1.narrow t2: $r.intp.global.Type = None.type scala> (t1.getClass, t2.getClass) res20: (Class[?0], Class[?0]) forSome { type ?0 <: $r.intp.global.Type; type ?0 <: $r.intp.global.Type } = (class scala.reflect.internal.Types$ModuleTypeRef,class scala.reflect.internal.Types$UniqueSingleType) scala> ((t1 =:= t2, t2 =:= t1, t1 <:< t2, t2 <:< t1)) res21: (Boolean, Boolean, Boolean, Boolean) = (true,true,true,true)

In principle this class is only subclassed by compiler-generated partial functions arising from matches. Either - the apply method (old-style partialfun) or - the applyOrElse method (current scheme) must be overridden, and the isDefinedAt method implemented. The applyOrElse method implementation is provided to ease the transition from the old scheme, since starr still generates old-style PartialFunctions, but locker's library has the new AbstractPartialFunction. Thus, this implementation is intended as a drop-in replacement for the old partial function, and does not require changes to the compiler. (compiler patches, both for old and new-style pattern matching, follow) - runtime.AbstractPartialFunction is based on PartialFunction.WithDefault Original version of FunctionWithDefault by Odersky (http://article.gmane.org/gmane.comp.lang.scala.internals/4032) - better performance for OrElse#applyOrElse, OrElse#lift, PF.cond - new combinator methods: PF#run, PF#runWith, PF.apply authored by @pavelpavlov, refactored by @adriaanm, review by @paulp
