This stub (courtesy of Jason Zaugg) keeps reflection API untouched and also fixes SBT. Win-win.

To reiterate the reasoning behind introduction of test methods into the API. I'd argue that the API duplication w.r.t flags is trumped by unified interface to tests and better encapsulation (especially since some of the flags have different meaning depending on whether the flaggee is a term or a type).

| * | SI-6175 reflect over classes with symbolic namesEugene Burmako2012-08-031-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Top-level classes with symbolic names (having binary names like $colon$colon) have previously been incorrectly treated as local classes by Scala reflection. As a result they were loaded as if they weren't pickled (i.e. as Java classes). Moreover this bug also had a more subtle, but more dangerous manifestation. If such a class has already been loaded indirectly by unpickling another class (which refers to it in its pickle) and then someone tried to load it explicitly via classToScala, then it would be loaded twice (once as a Scala artifact and once as a Java artifact). This is a short route to ambiguities and crashes. The fix first checks whether a class with a suspicious name (having dollars) can be loaded as a Scala artifact (by looking it up in a symbol table). If this fails, the class is then loaded in Java style (as it was done before). Ambiguous names that can be interpreted both ways (e.g. foo_$colon$colon) are first resolved as Scala and then as Java. This prioritization cannot lead to errors, because Scala and Java artifacts with the same name cannot coexist, therefore loading a Scala artifact won't shadow a homonymous Java artifact.

The @unchecked annotation has hereby been generalized beyond exhaustiveness to mean context-dependent "disable further compiler checking on this entity." Example of new usage: def f(x: Any) = x match { case xs: List[String @unchecked] => xs.head // no warning case xs: List[Int] => xs.head // unchecked warning } It turns out -unchecked has been put to other noisy uses such as the pattern matcher complaining about its budget like a careworn spouse. This actually simplified the path forward: I left -unchecked in place for that and general compatibility, so those warnings can be enabled as before with -unchecked. The erasure warnings I turned into regular warnings, subject to suppression by @unchecked. Review by @odersky.

* | | | | | | first stab at serialization of exprs and tagsEugene Burmako2012-08-023-5/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of trying to serialize the entire universe and failing miserably (which happens now), exprs and type tags will now serialize their creators and deserialize into scala.reflect.basis. Since creators produced by reification are not serializable right now, serialization will crash. That's a small improvement over state of the art functionality-wise, but it's a step forward robustness-wise. Next step in this direction is generation of serialization code for creators. Related issues: SI-5919 and SI-5908. Also see the discussion at scala-internals http://groups.google.com/group/scala-internals/browse_thread/thread/ef63f8b5bd194c7c
* | | | | | | moves Expr from api to baseEugene Burmako2012-08-0210-88/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the first step in supporting serialization for exprs and type tags. Generally speaking universes and mirrors cannot be serialized (even not taking into account all the amount of scalac-specific transient stuff, java mirrors use classloaders, which are not serializable). Hence we can only serialize tree and type creators, and deserialize them into the mirror we surely know will be there - the scala.reflect.basis.rootMirror. To do that we need to have exprs in scala.reflect.base. Luckily all the trees are already in base, we only need to move a single file to scala-library.jar. Another good news is that reification logic is simplified, because we don't have to special case exprs as being defined in ApiUniverseClass.

Crucial makro thingies (such as makro.Context or makro.internal.macroImpl) are temporarily left in place, because they are necessary for previous starr. Macro tests will be fixed in a dedicated commit, so that they don't pollute meaningful commits, making the life easy for reviewers and spelunkers.

Since then (for several months) this functionality hasn't proven to be useful, neither anyone on the mailing list or stackoverflow asked questions about it (even despite it was explicitly mentioned in the "cannot load macro impl" error message). Hence I suggest that it is totally unnecessary and should be removed.

Hence I'm replacing their RHSes with the universal ??? body. This way macro definitions defined in scala (for example, tag materialization macros or certain string formatters) won't stand in the way of the changes to the macro system.

The logic of those macros is hardwired into starr's fast track, so it doesn't rely on any of the subsystems of the macro engine to be located, bound and executed. But to trigger this logic we need to color these macros as macros, i.e. as term symbols having the MACRO flag. Currently this works automatically, because fast track macros (the same as regular macros) have their rhs in the "macro ???" form. Having seen the "macro" keyword, the compiler knows that the corresponding def declares a macro and sets the MACRO flag. As the latest refactoring attempt has shown, the "macro" in "macro ???" is unnecessary and might stand in the way of macro refactorings. After all if some symbol is in the fast track registry, then it's definitely a macro. Hence I'm changing the compiler to not need the "macro" keyword in declarations of fast track macros anymore.

I'd argue that the API duplication w.r.t flag sets is trumped by unified interface to tests and better encapsulation. Also updated the API to be easier to understand after prior exposure to Java or .NET reflection APIs: 1) Added typeParams to TypeSymbol and ClassSymbol. 2) Renamed MethodSymbol.resultType to returnType. 3) Removed the distinction between MethodSymbol.params vs MethodSymbol.allParams now we just have MethodSymbol.params: List[List[Symbol]].
