[rev:Adriaan] dummy implementation for update to fix deep function
compilation

Adjusted timeout in partest to get rid of spurious build failures.
|
| |
|
|
|
|
| |
Fixed the rest of the library deprecation warnings which had clear-ish
resolutions.

A bunch of cleanup on scriptrunner and fsc performed in a quest to fix
#1889. I understand why #1889 happens now but I believe fixing it is
going to require adjusting the logic in SymbolLoaders.

patches from today you can write something like this:
io.File("/etc/passwd").bytes grouped 512 map (_.sum) mkString ", "
res1: String = 45481, 46001, 45110, 45559, 45967, 29543

positioning change. Deleted instead of deprecated the two argument
version of Iterator.iterate since it did not exist in 2.7.

Fixed both versions of Iterator.iterate, which were a bit off, and gave
them type parameters.
Before: Iterator.iterate(5, 10)(_ + 1) toList
res0: List[Int] = List(6, 6, 6, 6, 6, 6, 6, 6, 6, 6)
After: Iterator.iterate(5L)(_ + 1) take 10 toList
res1: List[Long] = List(5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
Also, I deprecated the two argument version because
def iterate[T](start: T, len: Int)(f: T => T)
is identical to
iterate(start)(f) take len

val it = Stream continually (foo) iterator
it.foldLeft(...)
grows without bound, and there needs to be a simple
reliable way to repeatedly side effect.

Added two new methods to Iterator, each of which creates new Iterators
based on the original. Example usages:
(1 to 5).iterator grouped 3 toList =
List(List(1, 2, 3), List(4, 5))
(1 to 5).iterator sliding 3 toList =
List(List(1, 2, 3), List(2, 3, 4), List(3, 4, 5))
(1 to 10).iterator.sliding(4, step = 3) toList =
List(List(1, 2, 3, 4), List(4, 5, 6, 7), List(7, 8, 9, 10))

Various work on Codec/File/Source getting it in consistent shape and
ready for revisiting Iterator vs. Iterable and Source's assumption of
Char.
|
| |
|
|
|
| |
Adding more and fleshing out convenience functions in io.File.
|
| |
|
|
|
|
|

Restored missing pieces of some of my patches which were accidentally
reverted in r17680. This one includes StringBuilder cleanups and
tail-recursive drop in Iterator.
|
| |
|
|
|
| |
Restoring tail recursive version of List.dropWhile.
|
| |
|
|
|
|
| |
Improvements in positions assigned to expresssions using assignment
operators.

A variety of work on scala.io.{ File, Source } with changes
including:
getLines() now takes a line separator argument (defaults to platform
line.separator) and drops the newlines. scala.io.File adds several
convenience methods. The mechanisms for configuring Source are more
consistent.
This is not complete, performance issues remain to be investigated.
|

2. Relaxed bounds checking rules for existential types.

Fixed #1560 (which was a typing hole, so some library classes had to be
fixed)

improving fix of #2246: optimised isDifferentTypeConstructor
removed typeConstructor(Boolean), using hasDifferentTypeSymbol instead
switched to new subtyping algorithm (isSubType2)
substitution now uses appliedType
appliedType ensures Any/Nothing never have type args (so don't need to shortcut isSubArgs in firstTry when sym == AnyClass)
appliedType ignores TypeVar's for now (must deal with them, since they
arise during substitution) when tcpoly infer is integrated, TypeVar's
also have type arguments and this case in appliedType must be updated
maybe appliedType should become a member of Type (and rename to
applyTypeArgs?)

be more careful in isSubType for abstract types: type *constructors*
must be different, not the whole type, which includes type arguments
typeConstructor needed to instantiate the resulting type constructor
with fresh type arguments (derived from type params), otherwise we end
up in the higher-kinded case, and isDifferentTypeConstructor might try
to compare polytypes with type params
that have different (higher-order) arities --> this may still arise on other cases, though -- should fix this while working on #2210

fix for 513: use deep ForeachTypeTraverser in doTypeTraversal instead of
shallow one test case+checkfile for #513
