* SI-7657 clarifies the "macro overrides method" ruleEugene Burmako2013-07-146-18/+38
| | | | | | | | | | | | | | | Currently we allow macros to override non-abstract methods (in order to provide performance enhancements such as foreach for collections), and we also disallow macros to override abstract methods (otherwise downcasting might lead to AbstractMethodErrors). This patch fixes an oversight in the disallowing rule that prohibited macros from overriding a concrete method if that concrete method itself overrides an abstract method. RefCheck entertains all overriding pairs, not only the immediate ones, so the disallowing rule was triggered. Now macros can override abstract methods if and only if either the base type or the self type contain a matching non-abstract method.

The method argument must have the form "major.minor". The scaladoc is updated to reflect the new reality and a test is added under junit. Note that this implementation aims to be a simple compromise between the functional and imperative camps, that is, to be free of both closures and while loops. And to elicit no cruft like regexes and wrappers for strings. No doubt even more could be done in this department, but we don't wish to spoil the fun on codegolf.stackexchange.com. However, we might decide to sponsor a new site: codereviewpingpong.com For 2.10.x, javaSpecVersion is provided as a private member. The active test is under `run` and the `junit` test must bide its time in `pending`. For 2.11, the private members can be public and the app test replaced with the unit test.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | Calls to `materializeClassTag[T]` are replaced during reification with `implicitly[ClassTag[T]]` in the `reify` macro. This is done to avoid referring to symbols in scala-compiler.jar. Class- and Type-Tag materialization is treated in the same way. This commit positions the replacement trees to avoid triggering assertions under -Yrangepos.

Setter invocations are desugared from assignments of values to getters. If a typecheck of an assignment's lhs yields an invocation of a getter, then the assignment is rewritten into an invocation of a setter. However if a getter is a macro, then it just expands, destroying the prerequisite for desugaring. Therefore we need to disable expansion for the typecheck of an lhs. Similar thing happens to updateDynamic that first desugars a getter invocation into q"$target.updateDynamic($fieldName)" and then expects typedAssign to rewrite the corresponding Assign node into an additional application of a partially applied updateDynamic to a rhs. Here we also need to disable the typecheck of an lhs, because macros cannot be partially applied.
* | | | SI-7638 Superaccessor lookup after specializationVlad Ureche2013-07-081-0/+51
| |/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The crash was caused by a symbol lookup to rewire the super calls, done after pickler, but specialization added new traits and new members, thus making the super rewiring impossible. To avoid such problems, this patch moves symbol lookup after specialization, so the changes done by specialization (and miniboxing) become visible to mixin. NOTE: This patch will be followed by a similar patch to master. Review by @adriaanm or @retronym.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This performs method specialization inside a scope other than a {class, trait, object}: could be another method or a value. This specialization is much simpler, since there is no need to record the new members in the class signature, their signatures are only visible locally. It works according to the usual logic: - we use normalizeMember to create the specialized symbols - we leave DefDef stubs in the tree that are later filled in by tree duplication and adaptation The solution is limited by SI-7579: since the duplicator loses the sym annotations when duplicating, this expansion and rewiring can only take place in code that has not been subject to duplication. You can see the test case for an example. Review by @dragos, @paulp or @axel22.

This has the undesirable side effect of prohibiting partial functions literals in method bodies of a value class. The intention of that prohibition was to avoid problems in code using Type Tests, such as: class C(val inner: A) extends AnyVal { class D } def foo(a: Any, other: C) = a match { case _ : other.D } Here, the pattern usually checks that `a.$outer == other`. But that is incongruent with the way that `other` is erased to `A`. However, not all nested classes could lead us into this trap. This commit slightly relaxes the restriction to allow anonymous classes, which can't appear in a type test. The test shows that the translation generates working code.

But if a symbol is created during duplication, which runs after specialization, its info is not visited and thus the corresponding tree is not specialized. One manifestation is the following: ``` object Test { class Parent[@specialized(Int) T] def spec_method[@specialized(Int) T](t: T, expectedXSuper: String) = { class X extends Parent[T]() // even in the specialized variant, the local X class // doesn't extend Parent$mcI$sp, since its symbol has // been created after specialization and was not seen // by specialzation's info transformer. ... } } ``` We can fix this by forcing duplication to take place before specialization.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the `split` method of the `ParTrieMap` iterator threw an exception when splitting a splitter that iterated over nodes whose hash codes collide. This was due to reusing the iterator of the list of colliding keys rather than creating a new splitter. This commit changes the `subdivide` method to create a new iterator using the factory method of the current trie map iterator rather than returning a `LinearSeqLike` iterator.

It uses ASM to generate an interface with default methods then exercises that interface from Scala. Surprisingly no changes are necessary to the Scala code base to support reading format 52 class files. Because the test can only run under JDK 8, the JDK version is checked and the expected output is synthesized for previous versions.

It failed to find such super calls if they were nested in a Block, which can happens when using named or default arguments. This commit makes that code peer into Blocks to correctly partition the constructor statements. This change doesn't affect the result of run/t4680.scala, which was mentioned in nearby comments and which chronicles bugs with DelayedInit when used in inheritance hierarchies.

When it is too big for a single String, it is split into an array of Strings in a different annotation, ScalaLongSignature. The enclosed test, with a class containing 3000 methods, uses the latter. It exposes a bug in the way runtime reflection decodes that data. It must concatentate and *then* decode, rather that the other way around.

Part of this happens in `Typer#stabilize`. This was trying to determine if an Ident or Select node was a call to `getClass` by merits of the name of the tree's symbol and by checking that the its type (if it was a MethodType or PolyType) had no parameters in the primary parameter list. Overloaded user defined `getClass` methods confused this check. In the enclosed test case, the tree `definitions.this.getClass` had an `OverloadedType`, and such types always report an empty list of `params`. This commit: - changes `stabilize` to use `isGetClass`, rather than the homebrew check - changes `isGetClass` to consider a `Set[Symbol]` containing all `getClass` variants. This moves some similar code from `Erasure` to `Definitions` - keeps a fast negative path in `isGetClass` based on the symbol's name

However unlike fields, methods and constructors, inner classes don't need to be entered explicitly - they are entered implicitly when being loaded. This patch fixes the double-enter problem, make sure that enter-on-load uses the correct owner, and also hardens jclassAsScala against double enters that can occur in a different scenario.
