| * | | SI-9369 Fix pattern matcher warnings for diamond shaped inheritance.Gerard Basler2015-09-122-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A previous optimization (d44a86f432a7f9ca250b014acdeab02ac9f2c304) for pattern matcher exhaustivity checks used a smarter encoding to ensure that the scrutinee can be equal to one child only. However, in case of traits between the root and leave type, a child can be of several types and these types should not be in a mutually exclusive group. A simple solution (hat tip to retronym) is to just put traits and classes into separate groups.

For example, compiling: ``` def foo(c: Ctx)(l: c.Tree): Unit = { val l2: c.Tree = l } ``` Results in the following AST: ``` def foo(c: Ctx, l: Ctx#Tree): Unit = { val l$1: Ctx#Tree = l.asInstanceOf[Ctx#Tree] val l2: c.Tree = l$1 // no, not really, it's not. } ``` Of course, this is incorrect, since `l$1` has type `Ctx#Tree`, which is not a subtype of `c.Tree`. So what we need to do is to use the pre-uncurry type when creating `l$1`, which is `c.Tree` and is correct. Now, there are two additional problems: 1. when varargs and byname params are involved, the uncurry transformation desugares these special cases to actual typerefs, eg: ``` T* ~> Seq[T] (Scala-defined varargs) T* ~> Array[T] (Java-defined varargs) =>T ~> Function0[T] (by name params) ``` we use the DesugaredParameterType object (defined in scala.reflect.internal.transform.UnCurry) to redo this desugaring manually here 2. the type needs to be normalized, since `gen.mkCast` checks this (no HK here, just aliases have to be expanded before handing the type to `gen.mkAttributedCast`, which calls `gen.mkCast`)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some extra synthetic code generated under this mode failed to escape input before adding it to a literal string. It used to get away with this most of the time by triple quoting the literal. This commit reuses Scala string escaping logic buried in `Constant` to do this properly. Actually, the proper approach would be to build the synthetic code with trees and quasiquotes, and avoid the mess of stringly-genererated code. I threw in some defensive hygiene for the reference to `Nil` while I was in the neighbourhood.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When invoking a higher-order method and the value passed for the SAM type is either a function literal or a parameter of the callsite method, inline the higher-order method into the callee. This is a first version, the heuristics will be refined further.

When an instruction throws, the first handler in the list that covers the instruction and matches the type is executed. For nested handlers, it is the job of the compiler to add them to the handler table in the correct order. When inlining a method, the handlers of the callee are prepended to the list of handlers in the callsite method. This ensures that the callee's handlers are tested first if an exception is thrown in the inlined code.

This commit makes `mkAttributedRef` special case static owners by referring the the corresponding module, instead.

For example, `trait T[@spec A] { def t(a: A) }` gives rise to `def t(a: Int)` under the type environment `A=Int`. This commit avoids doing this for specialized traits, only classes have these overrides now. The motivation is to make it simpler to use specialized interfaces (like `T$mcI$sp` from the example above) as Java functional interfaces.

This is superfluous and problematic when we start adding default methods to the interfaces. The subsequent commit will remove them.

By the same token, pun intended, char literals accept unicode escapes the same as string literals, including `\u000A`. This commit adds the usual exclusions (CR, NL, SU). The spec is outdated in outlawing chars that are not "printable", in particular, the ASCII control codes. The original intention may have been that the ordinary string escapes are required, such as "\b\n". Note that some common escapes are absent, such as "\a".

Only one import from Predef is retained for special treatment. This is simple and sane. The test shows that `import Predef._` restores Predef implicits even if a user-defined term would normally be in scope. A smart `:import` command to turn off or quarantine imports explicitly would allow fine-grained control.

| | |_|_|_|/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous implementation of `mutable.TreeSet` uses a mutable reference to an immutable red-black tree as its underlying data structure. That leads to unnecessary objects being created, which can be a problem in systems with limited resources. It also has reduced performance when compared with common mutable implementations. In this commit `mutable.TreeSet` is changed so that it uses the recently created `mutable.RedBlackTree` as its underlying data structure. Specialized red-black tree methods were created for working with keys for efficiency reasons. The new implementation is source-compatible with the previous one, although its serialized representation obviously changes. Closes [SI-6938](https://issues.scala-lang.org/browse/SI-6938).

Constant propagation was added under -optimize in Scala 2.11.0-M3, in PR #2214. For example, we might know that a variable must hold one of a set of values (`Possible`). Or, we could track that it must *not* be of of a set of value (`Impossible`). The test case in the bug report was enough to create comparison: v1 == v2 // where V1 = Possible(Set(true, false)) // V2 = Possible(Set(true, false)) This test was considered to be always true, due to a bug in `Possible#mightNotEqual`. The only time we can be sure that `Possible(p1) mightNotEquals Possible(p2)` is if `p1` and `p2` are the same singleton set. This commit changes this method to implement this logic. The starting assumption for all values is currently `Impossible(Set())`, although it would also be reasonable to represent an unknown boolean variable as `Possible(Set(true, false))`, given the finite and small domain. I tried to change the starting assumption for boolean locals in exactly this manner, and that brings the bug into sharp focus. Under this patch: https://github.com/retronym/scala/commit/e564fe522d This code: def test(a: Boolean, b: Boolean) = a == b Compiles to: public boolean test(boolean, boolean); Code: 0: iconst_1 1: ireturn Note: the enclosed test case does not list `-optimize` in a `.flags` file, I'm relying on that being passed in by the validation build. I've tested locally with that option, though.

These NPEs appear when recomputing the lazy val when deserializaing the object. This commit disables the field nulling if the lazy val is marked transient. The post-mixin tree in the enclosed test changes as follows: ``` --- sandbox/old.log 2015-07-27 15:48:03.000000000 +1000 +++ sandbox/new.log 2015-07-27 15:47:56.000000000 +1000 @@ -1,61 +1,54 @@ [[syntax trees at end of mixin]] // t9365.scala package <empty> { class Test extends Object with Serializable { @transient @volatile private[this] var bitmap$trans$0: Boolean = false; private def foo$lzycompute(): Object = { { Test.this.synchronized({ if (Test.this.bitmap$trans$0.unary_!()) { Test.this.foo = Test.this.x.apply(); Test.this.bitmap$trans$0 = true; () }; scala.runtime.BoxedUnit.UNIT }); - Test.this.x = null + () }; Test.this.foo }; ``` In addition to the test from the ticket, I've added a reflection based test that directly tests the nulling. This complements the test added in 449f2a7473, the fix for SI-720, which passes by virtue of not exhausting the heap.
