* SI-8143 Regressions with override checks, private membersJason Zaugg2014-01-141-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | These regressed in e609f1f20b, which excluded all private methods from overriding checks. We should only exclude private[this] members on the low end of a pair, as was done before that commit, and, we must also exclude private members on the high side. Why? Warning: reverse engineered intuition follows. We need to report an error when if a private method in a subclass has matches a less-private method in the super class and report an error, lest the user be fooled into thinking it might be invoked virtually. On the other hand, adding a private method to a super class shouldn't invalidate the choice names of public members in its superclasses. I've removed the test case added by that commit and will lodge a reworked version of it that Paul provided as a new issue. That shows a bug with qualified private + inheritance. In addition, the expectation of `neg/accesses.check` is reverted to its 2.10.3 version, which I believe is correct. When it was changed in e609f1f20b it sprouted a variation, `neg/accesses-2`, which has now changed behaviour. The intent of that test will be captured in the aforementioned issue covering qualified private inheritance.
* Generalize OverridingPairs to SymbolPairs.Paul Phillips2013-10-051-0/+17
Increases your chance of knowing what is going on in OverridingPairs. Introduces some new abstractions which I hope for your own sakes you will put to use in some way: RelativeTo: operations relative to a prefix SymbolPair: two symbols being compared for something, and the enclosing class where the comparison is being performed Fixed a minor bug with access by accident by way of more principled pair analysis. See run/private-override.scala. Upgraded the error message issued on certain conflicts to give the line numbers of both conflicting methods, as opposed to just one and you go hunting.
