* SI-8173 add support for patterns like init :+ last to quasiquotesDenys Shabalin2014-02-023-40/+53
| | | | | | | | | | | | Adds support for patterns like: val q"{ ..$init; $last }" = q"{ a; b; c }" // init == List(q"a", q"b") // last == q"c" Which under the hood get compiled as `:+` patterns: SyntacticBlock(init :+ last)

| | | | | | | | | | | | | | | | - move "erroneous type" diagnostic into a crash recovery handler, rather than running it proactively - move the "unexpanded macros" check into refchecks. Cuts this phase in half, from about 1% of compile time to 0.5%.

| | | | | | | | | | | | | | | | | | This annotation was introduced to allow us to mark methods within a specialized trait as immune from specialization. In particular, this is desirable for `Function1.{andThen, compose}`. However, it seems we need to check for this in two places in the specialization code base. The feature is now backed with a test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This commit balances this out by prohibiting `AnyVal`, as well. The enclosed test shows that this case is now prevented. If multiple implicits views are applicable, the ambiguity error is still raised; these check comes right at the end. Maybe that ought to be changed, but I don't think it matters too much. I've also disabled this prohibition under -Xsource:2.10.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | More penance. Extend the unit test and don't include CR in the line text. This is obvious, which shows how dangerous it is to refactor without unit tests. My very favorite bugs are off-by-one and EOL handling, followed closely by off-by-Int.MaxValue.

The failure mode is kind of amusing: a while loop in `lineToString` would count all the way to `Int.MaxValue`, and integer overflow would foil a bounds check when looking for the 'LF' in 'CR'-'LF'. Given that we're not a style checker to enforce that source files end in a new-line, this commit accounts for EOF, and fixed the overflow problem too. A JUnit test exercises the bug and a few other variations of `lineContent`. While i was in the neighbourhood, I opted for a more efficient means to slice out that line.

But, if this is going to be unreasonably long, it is shortened with the help of a MD5 hash. However, after this shortening takes place, we sneakily add one more character (the infamous '$') to the name when it is used for the module class. It is thus possible to exceed the limit by one. The enclosed test failed on Mac with "filename too long" because of this. I have also tested for trait implementatation classes, but these seem to be suffixed with "$class" before the name compactification runs, so they weren't actually a problem. This change is binary incompatible as separately compiled defintions and usages of named, inner classes need to agree on this setting. Most typically, however, these long names crop up for inner anonymous classes / functions, which are not prone to the binary incompatiblity, assuming that their creation hasn't be inlined to a separately compiled client.

Splicing vale into implicit argument list automatically adds implicit flag to them: val x = q"val x: Int" q"def foo(implicit $x)" // <=> q"def foo(implicit x: Int)" 2. One might extract implicit argument list separately from other argument lists: val q”def foo(...$argss)(implicit ..$impl)" = q"def foo(implicit x: Int) // argss is Nil, impl contains valdef for x But this doesn't require you to always extract it separatly: val q”def foo(...$argss)" = q"def foo(implicit x: Int) // argss contains valdef for x

This made confusing things like possible: val x = TermName(“x”) q”def foo($x)” Now you can either splice trees in that position (ValDefs) or you have to provide type if you splice a name.

So we can't filter based on the number of elements extracted but rather filter on type of a tree.

Fresh names now also contain dollars to exclude clashes with supported user-defined names (the ones without dollar signs). This doesn’t fix the bug, because per-Global counters get created anew every time a new Global is instantiated, and that provides some potential for name clashes even for def macros, but at least it completely excludes clashes in typical situations.

While simplifying one use case (indexed access) it complicated ability to check if symbol at hand is in fact a tuple, product or function: (1 to 22).map(TupleClass).toList.contains(symbol) To cover this extra use case we add a seq method to the variable arity class definitions that exposes a corresponding sequence of class symbols: TupleClass.seq.contains(symbol)
