    Fixes example in Type.asSeenFrom

    densh authored
    It was written in some form of non-executable pseudo-code before and
    that might be quite confusing for people who are not familiar with scala
    reflection.

    Fix for SI-6600, regression with ScalaNumber.

    paulp authored
    Not much in the end; I divided ScalaNumericConversions
    into two traits such that the ScalaNumericAnyConversions can
    be used in value classes, and ScalaNumericConversions can
    override methods in ScalaNumber (since one trait cannot do
    both those things.)
    
    The fact that ScalaNumber is privileged for equality but a) extends
    java.lang.Number and therefore b) cannot be a value class is something
    we will want to revisit real soon.

    SI-6562 Fix crash with class nested in @inline method

    retronym authored gkossakowski committed
    e6b4204 moved access widenings from ExplicitOuter to
    SuperAccessors to reflect them in pickled signatures so
    that the inliner can take advantage of them under separate
    compilation.
    
    The followup discussion [1] determined that this wasn't
    the right solution: while it enabled new separate compilation
    inlinings, it failed to widen access of outer pointers and
    hence prevented certain inlinings.
    
    A better solution was proposed: modify the inliner to know
    that access widening is guaranteed to have happened in
    ExplicitOuter for any field accessed by an @inline-d method
    body, rather than relying solely on the pickled types.
    
    But this hasn't happened yet. In the meantime 07f9429 / #1121
    reinstated the access widening to SuperAccessors, but took a
    slightly different approach, using `Symbol#enclMethod` rather
    than `closestEnclMethod`. That deviation triggers SI-6562.
    
    This commit goes back to `closestEnclMethod`.

    SI-6556 no assert for surprising ctor result type

    odersky authored adriaanm committed
    Previous fix to value classes uncovered some questionable cases in the backend where result types of constructor signatures are surprising. It's not a big deal because these types will be ignored afterwards anyway. But
    the method uncovered some questionable situations which we should follow up on. However, breaking 2.9 code because of this is way too harsh. That's why the asserts were converted to warnings.

    Fixes SI-6500 by making erasure more regular.

    odersky authored
    With the introduction of value classes, erasure uses specialErasure where a value class C with underlying type T is unboxed to an ErasedValueType. ErasedValue types are eliminated on phase later, in post-erasure. This was done everywhere, except in the parameter types of bridge methods. That was a mistale, because that way  bridge methods could not do the boxing/unboxing logic triggered by ErasedValueTypes.
    
    Note: there is one remaining use of erasure (not specialErasure) in Erasure.scala. I put in a comment why that is OK.

    Only exclude hashCode and equals from being overridden in
    value classes, not other synthetics which may turn up such
    as case class methods.

  1. @hubertp

    Fixes SI-5031 for separate compilation scenario.

    hubertp authored
    When you have a conflicting member in package object and normal package that share the same namespace we remove the latter ClassSymbol from the scope. Now, this has an unpleasant consequence that companionClass/companionModule/companionSymbol no longer work correctly as they rely on finding the correspondent symbol using decls of the owner.
    This fixes the problem of SI-5031 for separate compilation. Why the above change matters for finding foo.bar.Foo? Because when parsing the class we needed information about the static module (and we have the correct module symbol when completing the info). It's just that 043ce6d relied on no longer valid assumptions. So we were getting NoSymbol and sym.exist was failing.
    
    Obviously a more complete solution would be better if we didn't rely on the scope but that's too big to change for 2.10.0.
  2. @retronym

    Wider use and a new variant of typedPos.

    retronym authored
    It's safe to replace `localTyper.typed(atPos(pos)(tree))` with
    `localTyper.typedPos(pos)(tree)` given that we're all in the
    same cake and we'll get to the same `atPos`.

    SI-6575 Plug inference leak of AbstractPartialFun

    retronym authored
    Usually this isn't needed, as partial functions can only be
    defined with an expected type. But if that expected type is
    and inherited method return type, the actual type of the partial
    function literal is used, and the implementation detail of
    `AbstractPartialFunction[A, B] with Serializable` leaks out.
    
    After this change, the inferred types match those from
    Scala 2.9.2.

    Don't prohibit equals and hashCode in universal traits;
    instead, always override them in value classes.
Something went wrong with that request. Please try again.
