| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At this commit the statistics when compiling src/library are as follows. These counts are precise, collected by a modified Function1 which counts every instantiation of every implementing class. The net result is 27 million fewer allocations, over a 20% drop. // master (5b5635ee9d), total and top five by count: Total Function1 allocations: 128,805,865 scala.collection.immutable.$colon$colon 26781958 scala.collection.mutable.ListBuffer 15365174 scala.collection.TraversableLike$$anonfun$map$1 9127787 scala.collection.generic.Growable$$anonfun$$plus$plus$eq$1 4636154 scala.collection.mutable.StringBuilder 3531211 // After these commits, total and top five by count: Total Function1 allocations: 101,865,721 scala.collection.immutable.$colon$colon 26993704 scala.collection.mutable.ListBuffer 15319656 scala.collection.TraversableLike$$anonfun$map$1 7585019 scala.reflect.internal.Types$MethodType$$anonfun$paramTypes$1 2447307 scala.reflect.internal.Types$SubstSymMap 2436088

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fix still requires macro developers to be careful about sharing trees by references, because attributed DefTrees will still bring trouble. However this is an improvement, because it doesn't make matters worse and automatically fixes situations similar to one in the test. A much more thorough discussion with a number of open questions left: http://groups.google.com/group/scala-internals/browse_thread/thread/492560d941b315cc

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change allows to pattern match over type names, term names and modifiers. Otherwise it can be quite painful to match over complex trees as each name or modifiers requires a guard. This pull request also changes the name of default constructor for term and type names i.e. TypeName(s) instead of newTermName(s). This is shorter to type, more consistent with the rest of reflection api and consistent with the way it will be pattern matched later on.

* | | SI-6846, regression in type constructor inference.Paul Phillips2012-12-282-13/+12
| | | | | | | | | | | | | | | | | | | | | In 658ba1b4e6 some inference was gained and some was lost. In this commit we regain what was lost and gain even more. Dealiasing and widening should be fully handled now, as illustrated by the test case.
* | | Cleaning up type alias usage.Paul Phillips2012-12-286-43/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I determined that many if not most of the calls to .normalize have no intent beyond dealiasing the type. In light of this I went call site to call site knocking on doors and asking why exactly they were calling any of .normalize .widen.normalize .normalize.widen and if I didn't like their answers they found themselves introduced to 'dropAliasesAndSingleTypes', the recursive widener and dealiaser which I concluded is necessary after all. Discovered that the object called 'deAlias' actually depends upon calling 'normalize', not 'dealias'. Decided this was sufficient cause to rename it to 'normalizeAliases'. Created dealiasWiden and dealiasWidenChain. Dropped dropAliasesAndSingleTypes in favor of methods on Type alongside dealias and widen (Type#dealiasWiden). These should reduce the number of "hey, the type alias doesn't work" bugs.
* | | Shored up a hidden dealiasing dependency.Paul Phillips2012-12-281-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Like the comment says: // This way typedNew always returns a dealiased type. This // used to happen by accident for instantiations without type // arguments due to ad hoc code in typedTypeConstructor, and // annotations depended on it (to the extent that they worked, // which they did not when given a parameterized type alias // which dealiased to an annotation.) typedTypeConstructor // dealiases nothing now, but it makes sense for a "new" to // always be given a dealiased type. PS: Simply running the test suite is becoming more difficult all the time. Running "ant test" includes time consuming activities of niche interest such as all the osgi tests, but test.suite manages to miss the continuations tests.
* | | Fix and simplify typedTypeConstructor.Paul Phillips2012-12-281-21/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Investigating the useful output of devWarning (-Xdev people, it's good for you) led back to this comment: "normalize to get rid of type aliases" You may know that this is not all the normalizing does. Normalizing also turns TypeRefs with unapplied arguments (type constructors) into PolyTypes. That means that when typedParentType would call typedTypeConstructor it would find its parent had morphed into a PolyType. Not that it noticed; it would blithely continue and unwittingly discard the type arguments by way of appliedType (which smoothly logged the incident, thank you appliedType.) The simplification of typedTypeConstructor: There was a whole complicated special treatment of AnyRef here which appears to have become unnecessary. Removed special treatment and lit a candle for regularity. Updated lots of tests regarding newly not-so-special AnyRef.
