* Merge pull request #1437 from paulp/typevar-suspensionGrzegorz Kossakowski2012-10-0210-9/+301
|\ | | | | Typevar suspension
| * Recovered a bunch of deleted tests.Paul Phillips2012-10-016-0/+275
| | | | | | | | | | | | | | | | | | | | | | Are we in the habit of simply deleting tests when they become inconvenient? A comment referenced test "0851" as the example of why the code was needed; the test was deleted years ago for no reason I can see except that it was not passing at the time. Words fail me. Public Service Announcement: tests which are failing are the MOST USEFUL tests. DON'T DELETE THEM!
| * Fix for TypeVar instantiation.Paul Phillips2012-10-014-9/+26

Followed that to this code in TypeVar: val newInst = wildcardToTypeVarMap(tp) (constr isWithinBounds newInst) && { setInst(tp); true } -------^ That was the obstacle to symmetry, because it creates a cycle in e.g. run/existentials. Kept pulling the string, came back to my own comment of long ago: !!! Is it somehow guaranteed that this will not break under nesting? In general one has to save and restore the contents of the field... Decided that uncertainty could no longer be tolerated. Unless it can be proven somehow that there will never be crosstalk among the save/suspension points, we should do it this way even if nothing demands it yet. What's in this commit: - Made isPopulated symmetric. - Made setInst resistant to TypeVar cycles. - Fixed above mentioned bug in registerTypeEquality. - Added some rigor to the suspension/unsuspension of TypeVars so it will not break under nesting. - Recovered pos/t0851.scala from its deletion.

| * | Fix for SI-4729, overriding java varargs in scala.Paul Phillips2012-09-293-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was a bad interaction between anonymous subclasses and bridge methods. new Foo { override def bar = 5 } Scala figures it can mark "bar" private since hey, what's the difference. The problem is that if it was overriding a java-defined varargs method in scala, the bridge method logic says "Oh, it's private? Then you don't need a varargs bridge." Hey scalac, you're the one that made me private! You made me like this! You!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I will again defer to a comment. /** Given classes A and B, can it be shown that nothing which is * an A will ever be a subclass of something which is a B? This * entails not only showing that !(A isSubClass B) but that the * same is true of all their subclasses. Restated for symmetry: * the same value cannot be a member of both A and B. * * 1) A must not be a subclass of B, nor B of A (the trivial check) * 2) One of A or B must be completely knowable (see isKnowable) * 3) Assuming A is knowable, the proposition is true if * !(A' isSubClass B) for all A', where A' is a subclass of A. * * Due to symmetry, the last condition applies as well in reverse. */
| | * Restored warning for impossible type tests.Paul Phillips2012-09-261-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I had this in before, then removed it since it is sometimes redundant with an error message later issued by the pattern matcher (e.g. scrutinee is incompatible with pattern type.) However it also catches a lot of cases which are not errors, so I think the modest redundancy is tolerable for now. I also enhanced the logic for recognizing impossible type tests, taking sealedness into account.

The comment says is better than I can. /** On pattern matcher checkability: * * Consider a pattern match of this form: (x: X) match { case _: P => } * * There are four possibilities to consider: * [P1] X will always conform to P * [P2] x will never conform to P * [P3] X <: P if some runtime test is true * [P4] X cannot be checked against P * * The first two cases correspond to those when there is enough static * information to say X <: P or that !(X <: P) for all X and P. * The fourth case includes unknown abstract types or structural * refinements appearing within a pattern. * * The third case is the interesting one. We designate another type, XR, * which is essentially the intersection of X and |P|, where |P| is * the erasure of P. If XR <: P, then no warning is emitted. * * Examples of how this info is put to use: * sealed trait A[T] ; class B[T] extends A[T] * def f(x: B[Int]) = x match { case _: A[Int] if true => } * def g(x: A[Int]) = x match { case _: B[Int] => } * * `f` requires no warning because X=B[Int], P=A[Int], and B[Int] <:< A[Int]. * `g` requires no warning because X=A[Int], P=B[Int], XR=B[Int], and B[Int] <:< B[Int]. * XR=B[Int] because a value of type A[Int] which is tested to be a B can * only be a B[Int], due to the definition of B (B[T] extends A[T].) * * This is something like asSeenFrom, only rather than asking what a type looks * like from the point of view of one of its base classes, we ask what it looks * like from the point of view of one of its subclasses. */

| * | | exposes Position.source as SourceFileEugene Burmako2012-09-272-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was useful to pretend that SourceFile isn't a part of the API, when it's physical location was in scala-compiler.jar. Afterwards Position and SourceFile have been moved to scala-reflect.jar, and (what's more important) scala-reflect.jar gained experimental status, meaning that we're not bound by backward compatibility in 2.10.0. Therefore I'd say we should expose a full-fledged SourceFile in Position.source (just as we do for Symbol.associatedFile) and later find out how to strip down its interface to something suitable for public consumption.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was an interesting idea to give macro developers control over front ends, but it hasn't given any visible results. To the contrast, front ends have proven useful for toolboxes to easily control what errors get printed where. Therefore I'm moving front ends to scala-compiler.jar to clean up the API. Yay for scaladoc-driven development!

For more information, see https://issues.scala-lang.org/browse/SI-6412 and http://groups.google.com/group/scala-internals/browse_thread/thread/eabcf3d406dab8b2 In comparison with https://github.com/scala/scala/commit/b403c1d, the original commit that implemented the fix, this one doesn't crash tests. The problem with the original commit was that it called tryFixup() before updating the cache, leading to stack overflows.

As the performance testing in https://github.com/scala/scala/pull/1380 shows, this commit introduces a ~2% performance regression of compilation speed. Unfortunately all known solutions to the bug at hand (A, B & C - all of those) introduce perf regressions (see the pull request linked above for details). However we're under severe time pressure, so there's no more time to explore. Therefore I suggest this is reasonable to accept this performance hit, because we've just gained 6% from removing scala.reflect.base, and even before that we were well within our performance goal for 2.10.0-final.
