Guards against bridge methods that clash with other methods. Two
tests: The neg test is the original ticket. The run test tweaks
things slightly so that the generated bridge method does not clash,
and tests that the necessary unboxings are indeed performed at
runtime.

SI-5943 toolboxes now autoimport Predef and scala
|
| |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
Previously tb.typeCheck used default typer, which builds upon NoContext.
Changing the context to analyzer.rootContext(NoCompilationUnit, EmptyTree)
fixed the missing imports problem.
Unfortunately this doesn't help in cases like "math.sqrt(4.0)" because of
https://issues.scala-lang.org/browse/SI-6393. But anyways I'm adding
this test case to pending.

existentially typed macro expansions now work fine
|
| | |
| | |
| | |
| | |
| | |
| | | |
Now, when the existential reification bug is fixed, I've been able
to take a look at SI-5418, and, apparently, the problem with importers
has fixed itself during these 9 months of the bug being active.

If one tries to compile the following code with the parent of this commit:
ru.reify(new Object().getClass)
then the following error will occur:
Test.scala:2: error: type mismatch;
found : $u.Expr[Class[_ <: Object]]
required: reflect.runtime.universe.Expr[Class[?0(in value <local Test>)]]
where type ?0(in value <local Test>) <: Object
ru.reify(new Object().getClass)
^
This happens because macro expansions are always typechecked against the
return type of their macro definitions instantiated in the context of expandee.
In this case the expected type contains skolems which are incompatible
with wildcards in the type of the expansion.
I tried all the incantations I could think of - without any success.
Luckily I met Martin who pointed me at the same problem solved in adapt
(see the diff w.r.t Typers.scala).

SI-6392 wraps non-terms before typecheck/eval

Wrap non-term arguments of typecheck and eval, so that toolboxes
can work with full-fledged files (except for package declarations).

merges scala.reflect.base into scala.reflect.api
|
| | |
| | |
| | |
| | |
| | | |
As the experience has shown, there's no need for a separate layer of reflection
in scala-library.jar. Therefore I'm putting an end to it.

NameType is introduced in base.StandardNames#NamesBase to abstract away the
difference between term names and type names in order to encode common names
such as EMPTY or WILDCARD.
Flavor-specific name repositories, such as TermNames and TypeNames are supposed
to override NameType fixing it to correspondingly TermName or TypeName.
Unfortunately I completely overlooked this and as a result some standard names
were typed with insufficient precision, e.g. This(tpnme.EMPTY) didn't work.

Fixes SI-6354: improved error messages for Dynamic signature mismatches.

If an error occurs afer a Dynamic rewriting, augment the error message
with the rewritten tree and a hint to check the Dynamic method
signature.

SI-6287 fixes synthetic symbol clashes in toolbox

Apparently synthetic classes like $anonfun$1 have two properties:
1) Their names are generated using a counter unique to a compilation unit
2) After flatten they levitate to the nearest enclosing package
As a result if we use an empty package to wrap toolbox codegen,
then this package will soon be overflown by $anonfun$1 symbols, because:
1) New codegen session = new compilation unit = new counter which starts at 0
2) New codegen session = new anon funs that end up as children of empty package
Creating a freshly named package for each codegen session fixed the problem.
Now anonfuns from different sessions end up with different parents.

Because of using plain ExistentialType factory of a case class
typeToScala sometimes returned existentials with empty quantifieds.
Changing ExistentialType to newExistentialType, which simply returns
the underlying types if params are empty, fixed the problem.

Translation of Java types to Scala types has previously been
existentionalizing raw types of ParameterizedType arguments.
As shown in https://issues.scala-lang.org/browse/SI-6374
this leads to cyclic reference errors. If you wonder about the
mechanism of the error, take a look at the comments to the
aforementioned issue - there's a detailed explanation.
However calling rawToExistential is completely unnecessary, because
existential parameters of the results are immediately discarded,
and only prefix and symbol are used later on (which means that
existential extrapolation performed by rawToExistential also doesn't
after the result).
Finding out this was tough, but the rest was a piece of cake.
Getting rid of the call to rawToExistential when translating ParameterizedType
fixed the problem.

exception of keeping `@static` annotation in the library so we

it completely.

- Accept sugared applications such as x(1) if x implements Dynamic,

- When picking a dynamic rewrite for x.apply(1), favor applyDynamic
instead of the default selectDynamic.
