| | | | | | | | | | | | | | | | | | | | | | Only exhaustiveness checking should be disabled if the scrutinee of a match as annotated as `: @unchecked`. This was the pre-2.10.x behaviour. This also fixes a variation of the closed ticket, SI-6011. The exhaustiveness check is needed to safely fallback from emitting a table switch if duplicate cases are detected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | More interesting to test than it was to fix. The soft reference is now dereferenced once, the locally stored underlying value ascertained to be non-null, and the remainder of the references to the value use the local var. The enclosed test reliably NPEs without this patch.

This is a localized fix, but I'd be suprised if there weren't other places that suffered from the same problem.

| * | | Do not recompute stack frames when instrumenting bytecode.Grzegorz Kossakowski2013-01-242-25/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that we do not need to do that. See comment in `ProfilerVisitor.java`. Also, since recomputing stack frame map was the only reason we needed to implement `getCommonSuperClass` we can now remove its implementation that was causing problems on Java 7 due to a cyclic dependency involving class loader because we would try to load a class we are currently transforming and transformer is triggered just before classloading. //cc @namin who worked on this code with me.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We do not need to retransform classes once they are loaded. All instrumentation byte-code is pushed at loading time. This fixes a problem with Java 7 that was failing to add a transformer because we did not declare retransformation capability in `MANIFEST.MF` file in Java agent jar. Java 6 allowed to add transformer due to a bug.

| * | | Fix class loader issues in instrumentation tests.Nada Amin2013-01-241-2/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ASM ClassWriter uses a wimpy class loader when computing common superclasses. This could cause a ClassNotFoundException in the transform method (at reader.accept). This exception gets swallowed, resulting in a class that should be instrumented to silently not be. The fix is to override getCommonSuperClass to use the correct class loader. Trivia: This bug was discovered while 'stress-testing' this instrumentation scheme on the Coursera students, to check that they implement one method in terms of another in the assignment.

First building a large proposition that represents the match, and then converting to CNF tends to blow the stack. Luckily, it's easy to convert to CNF as we go. The optimization relies on `CNF(P1 /\ ... /\ PN) == CNF(P1) ++ CNF(...) ++ CNF(PN)`: Normalizing a conjunction of propositions yields the same formula as concatenating the normalized conjuncts. CNF conversion is expensive for large propositions, so we push it down into the conjunction and then concatenate the resulting arrays of clauses (which is cheap). (CNF converts a free-form proposition into an `Array[Set[Lit]]`, where: - the Array's elements are /\'ed together; - and the Set's elements are \/'ed; - a Lit is a possibly negated variable.) NOTE: - removeVarEq may throw an AnalysisBudget.Exception - also reworked the interface used to build formula, so that we can more easily plug in SAT4J when the time comes

Uncurry treated these like regular method arguments, and performed the liftedTree() transformation, which ensures that try expressions are only used in a statement position. Even try in statement position of a block used as such an argument are subject to the same transform. This transform stems from the JVM limitation, that try/catch does not leave a value on the stack. See b194446. This commit changes Uncurry to avoid this transform for arguments to label jumps. This avoids needlessly indirect code, and enables tail call elimination in more cases. As an example, Scala 2.10.0 transforms the last method of the enclosed test case to: try { case <synthetic> val x1: Int = 1; case5(){ if (2.==(x1)) { val x2: Int = x1; matchEnd4({ { def liftedTree2(): Unit = try { throw new scala.runtime.NonLocalReturnControl[Unit](nonLocalReturnKey1, ()) } catch { case (e @ (_: ClassNotFoundException)) => () }; liftedTree2() }; TailrecAfterTryCatch.this.bad() }) } else case6() }; case6(){ matchEnd4(throw new MatchError(x1)) }; matchEnd4(x: Unit){ x } } catch { case (ex @ (_: scala.runtime.NonLocalReturnControl[Unit @unchecked])) => if (ex.key().eq(nonLocalReturnKey1)) ex.value() else throw ex } After this patch: @scala.annotation.tailrec final def bad(): Unit = { case <synthetic> val x1: Int = 1; case5(){ if (2.==(x1)) { <synthetic> val x2: Int = x1; matchEnd4({ try { return () } catch { case (e @ (_: ClassNotFoundException)) => () }; TailrecAfterTryCatch.this.bad() }) } else case6() }; case6(){ matchEnd4(throw new MatchError(x1)) }; matchEnd4(x: Unit){ x } }
