| | | | | | | | | | Fixed parallel ranges to use the same range logic under the hood, and not introduce code duplication. Slight fix in Tasks. No review.
* Fixing jvm 1.5 support for parallel collections.Aleksandar Pokopec2010-12-0917-41/+94
| | | | | | | | | | | | | | | | | | Special cased with thread pool executor scheduling. Fixed an ugly concurrency bug where futures returned by a thread pool executor didn't remove the task from the queue when cancel was called. Note to self and others: don't cancel futures returned by thread pool executors, it might lead to unexpected behaviour. Modified the executor to add new threads if all the active threads are syncing, in order to avoid deadlocks. Fixed a hidden bug in AdaptiveWorkStealingTasks, where correct behaviour depended on the execution order of the tasks. This didn't fail before with ForkJoinTasks, since there the execution order is well-defined. Scalachecked 1.5 & 1.6 support. No review.

| | | | | | | | | | Introducing scala.system, the product of a whirlwind couple of hours. More useful stuff than you can shake three sticks at. See the scala.system package object. It's even documented. And since it has methods error and exit, proceeded to deprecate the ones in Predef. No review.

| | | | | | | | | | | | | | Starting the mopping up now that names have some more sense of their place in the universe. Cleaned up some heavy multi-boolean logic. Added more documentation on the relationships between entities in Symbols and some other compiler things which often blur together. Fun fact: the incorrect usage of nme.ScalaObject in Contexts which I reported when first broaching the namespace subject became a compile time error during the writing of this patch, because there is no longer any such thing as nme.ScalaObject. It's a little bit like magic. No review.

| | | | | | | | | | | | | | | | | | | Generalizes catch blocks to include any PartialFunction[Throwable, T]. Existing catch blocks will compile exactly as before. Anything else (which mean: the token after CATCH is not a left brace, or it is a left brace not immediately followed by CASE) is desugared as follows: try body catch expr // becomes try body catch { case x => val catchFn = expr if (catchFn isDefinedAt x) catchFn(x) else throw x } Review by odersky.
* It's a big one!Paul Phillips2010-12-021-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TermName and TypeName are exposed throughout the compiler based on what kind of name a given abstraction ought to have. (There remain places where one needs to create a name without knowing yet what it will be, and those will always be Names.) The nme object in the compiler now holds only term names. To reference a known type name, use tpnme: nme.List == ("List": TermName) tpnme.List == ("List": TypeName) The contents of nme and tpname are defined in traits, many of which are shared, so if a name should exist only as a Type and not a Term, it should be defined in CompilerTypeNames, but otherwise in CompilerTermNames or CompilerCommonNames. This is partially complete but I'm sure there are still many shared which should pick a side. Usage of .toTermName and .toTypeName is strongly discouraged. After the dust has settled, there will be very few places where it will make sense to hop between namespaces like that. There are some implicits to smooth everything out, most of which should be removable eventually. // these two are in no hurry to go anywhere String => TermName String => TypeName // but not String => Name: def view in the compiler is no longer implicit // these two are temporary, and can log when they kick off to help us flush // out remaining issues of "name migration" Name => TermName Name => TypeName There is more work to be done before we're properly protected from naming errors, but I will not allow another eight hour tragedy to befall lukas or anyone else! Review by rytz. (Formality.)

| | | | | | | | | | | | | A patch authored by martin to fix one of the big outstanding issues with -Ycheck. The typer had a vision of the world which fell to pieces if presented with a tree from after phase constructors. Now it is wiser: perhaps a bit sadder as well, but every typer must face this day sooner or later. Also removed the various passing tests from test/checker-tests, but still plenty of fascinating failures in there for anyone interested in helping push to the finish line! No review.
* More fiddling with checkSensible.Paul Phillips2010-12-012-8/+9
| | | | | | | | | | warnings. Fixed some bugs revealed by said warnings, and made some minor changes to avoid warnings. (Technically it's not a bug to have unrelated classes compare as equal, but it so often is a bug that it behooves us not to do it intentionally so the warnings stand out.) Disabled the most useful warning for the moment since it'd be wrong with some frequency. No review.

* Deprecated the @serializable annotation, introd...Lukas Rytz2010-11-306-28/+50
| | | | | | | | | | | | | | | | | | | Deprecated the @serializable annotation, introduce a new trait "scala.Serializable" which has to be extended instead (cross-platform). Known issues: - Companion objects of serializable classes (including case classes) are automatically made serializable. However, they don't extend "Serializable" statically because of the known difficulty (should be done before typing, but hard). - Writing "case class C() extends Serializable" gives "error: trait Serializable is inherited twice" - Functions are serializable, but don't extend Serializable dynamically (could be fixed by making FunctionN Serializable - shouldn't we?) Note that @SerialVersionUID continues to be an annotation; it generates a static field, which is not possible otherwise in scala. Review by dragos, extempore. Question to dragos: in JavaPlatform.isMaybeBoxed, why is there a test for "JavaSerializableClass"? Is that correct?

| | | | | | | It looks like the fix for #2318 was causing problems, so I gave it some more graceful failure. Leaving #2318 open because the implementation could still work harder to find the right method. No review.

| | | | | | | | | | | | | | | | | | The initial implementation of TraversableOnce could not supply concrete methods or even signatures for map and flatMap because they have different signatures in Iterator and TraversableLike. But we can take another approach which works out as nicely: 1) Create implicits which install those methods and flatten on TraversableOnce instances. 2) Generalize the signatures of flatten and flatMap to work with A => TraversableOnce[B] instead of A => Traversable[B]. And voila, you can mix and match Iterators and Traversables in a for comprehension, map, flatMap, and flatten, without the tedious process of sprinkling .iterator or .toList around to appease the compiler. No review.

| | | | | | | | | | | | | | | | | | | | | "I invite everyone to change this rule, and observe what breaks!" This much beloved comment from #1208 has been on my radar for two years. The worm has turned. Closes #1208. The inferred type of an object is now Foo.type instead of "object Foo". What once was this: scala> val x: Map[Int, Singleton] = Map(1 -> None) <console>:5: error: type mismatch; found : (Int, object None) required: (Int, Singleton) Now exudes a pleasing aura of workingness: scala> val x: Map[Int, Singleton] = Map(1 -> None) x: Map[Int,Singleton] = Map(1 -> None) No review.
