* SI-6810 Disallow EOL in char literalSom Snytt2015-06-291-3/+5
| | | | | | | | | | | | | | | | | It's clear that char literals are one-lined like normal string literals. By the same token, pun intended, char literals accept unicode escapes the same as string literals, including `\u000A`. This commit adds the usual exclusions (CR, NL, SU). The spec is outdated in outlawing chars that are not "printable", in particular, the ASCII control codes. The original intention may have been that the ordinary string escapes are required, such as "\b\n". Note that some common escapes are absent, such as "\a".

| * | SI-4147 Add an implementation of `mutable.TreeMap`Rui Gonçalves2015-05-304-0/+792
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit contains an implementation of a mutable red-black tree with focus on performance. It also contains a new `mutable.TreeMap` Scala collection that is backed by the aforementioned tree. The common generic factories and traits related to mutable sorted maps didn't exist yet, so this commit also adds them. Regarding performance, `TreeMap` overrides (from `MapLike` and `SortedMapLike`) all of the most common methods for maps and also those whose default implementations are asymptotically worse than direct red-black tree algorithms (e.g. `last`, `clear`). The `rangeImpl` method of `TreeMap` returns an instance of `TreeMapView`, an inner class of `TreeMap`. This view is backed by the same `RedBlackTree.Tree` instance, and therefore changes to the original map are reflected in the view and vice-versa. The semantics of mutating a view by adding and removing keys outside the view's range are the same of the current `mutable.TreeSet`. A bit less focus was given on the performance of views - in particular, getting the `size` of a `TreeMapView` is O(n) on the number of elements inside the view bounds. That can be improved in the future. In a future commit, `mutable.TreeSet` can be changed to be backed by this red-black tree implementation.

A first step is to use the recently introduced backend method `javaClassfileFlags`, which is now moved to BCodeAsmCommon. See its doc for an explanation. Then the flags of the enum class symbol were off. An enum is - final if none of its values has a class body - abstract if it has an abstract method (https://docs.oracle.com/javase/specs/jls/se7/html/jls-8.html#jls-8.9) When using the ClassfileParser: - ENUM was never added. I guess that's just an oversight. - ABSTRACT (together with SEALED) was always added. This is to enable exhaustiveness checking, see 3f7b8b5. This is a hack and we have to go through the class members in the backend to find out if the enum actually has the `ACC_ABSTRACT` flag or not. When using the JavaParser: - FINAL was never added. - ABSTRACT was never added. This commit fixes all of the above and tests cases (Java enum read from the classfile and from source).

Failing that, there's a fallback and an override. If instantiating the standard `jline.InteractiveReader` fails, we fall back to an embedded, shaded, version of jline, provided by `jline_embedded.InteractiveReader`. (Assume `import scala.tools.nsc.interpreter._` for this message.) The instantiation of `InteractiveReader` eagerly exercises jline, so that a linkage error will result if jline is missing or if the provided one is not binary compatible. The property `scala.repl.reader` overrides this behavior, if set to the FQN of a class that looks like `YourInteractiveReader` below. ``` class YourInteractiveReader(completer: () => Completion) extends InteractiveReader ``` The repl logs which classes it tried to instantiate under `-Ydebug`. # Changes to source & build The core of the repl (`src/repl`) no longer depends on jline. The jline interface is now in `src/repl-jline`. The embedded jline + our interface to it are generated by the `quick.repl` target. The build now also enforces that only `src/repl-jline` depends on jline. The sources in `src/repl` are now sure to be independent of it, though they do use reflection to instantiate a suitable subclass of `InteractiveReader`, as explained above. The `quick.repl` target builds the sources in `src/repl` and `src/repl-jline`, producing a jar for the `repl-jline` classes, which is then transformed using jarjar to obtain a shaded copy of the `scala.tools.nsc.interpreter.jline` package. Jarjar is used to combine the `jline` jar and the `repl-jline` into a new jar, rewriting package names as follows: - `org.fusesource` -> `scala.tools.fusesource_embedded` - `jline` -> `scala.tools.jline_embedded` - `scala.tools.nsc.interpreter.jline` -> `scala.tools.nsc.interpreter.jline_embedded` Classes not reachable from `scala.tools.**` are pruned, as well as empty dirs. The classes in the `repl-jline` jar as well as those in the rewritten one are copied to the repl's output directory. PS: The sbt build is not updated, sorry. PPS: A more recent fork of jarjar: https://github.com/shevek/jarjar.
| | * | Centralize dependencies on jlineAdriaan Moors2015-06-1715-273/+314
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Code that depends on jline is now in package `scala.tools.nsc.interpreter.jline`. To make this possible, remove the `entries` functionality from `History`, and add the `historicize` method. Also provide an overload for `asStrings`. Clean up a little along the way in `JLineHistory.scala` and `JLineReader.scala`. Next step: fall back to an embedded jline when the expected jline jar is not on the classpath. The gist of the refactor: https://gist.github.com/adriaanm/02e110d4da0a585480c1

| | | | | | | | | | | | | | | | | | | | | | | | Vector was intercepting only the IndexedSeq CanBuildFrom to quickly generate new vectors. Now it intercepts immutable.Seq and collection.Seq as well. There are other possibilities (collection.IndexedSeq), but they will probably arise rarely, and to avoid an absurdly long set of checks we would need a marker trait (that is not binary compatible).

First, an access to a public member of package protected class C can only be inlined if the destination class can access C. This is tested by t7582b. Second, an access to a protected member requires the receiver object to be a subtype of the class where the instruction is located. So when inlining such an access, we need to know the type of the receiver object - which we don't have. Therefore we don't inline in this case for now. This can be fixed once we have a type propagation analyis. https://github.com/scala-opt/scala/issues/13. This case is tested by t2106. Force kmpSliceSearch test to delambdafy:inline See discussion on https://github.com/scala/scala/pull/4505. The issue will go away when moving to indy-lambda.
