* Two annoying REPL things made less annoying:Paul Phillips2010-11-174-5/+126
| | | | | | | | | * ctrl-C will no longer kill the repl unless you hit it again * ctrl-Z will no longer make the repl useless because of jline In the service of the first I wrote signal handling code, which we can put to use in other ways as well. No review.
* Some profiling infrastructure.Paul Phillips2010-11-166-13/+165
| | | | | | | | | | | | | | | | | | | | | | | | | | I avoided creating any dependency on yourkit. In addition, there was no way to give arguments to the JVM without losing the ones defined in ANT_OPTS, which has been a massive pain for a while. So there is now "jvm.opts" which is simply appended to ANT_OPTS, e.g. % ant -Djvm.opts=-verbose [echo] Forking with JVM opts: -Xms1536M -Xmx2g -Xss1M -XX:MaxPermSize=192M -XX:+UseParallelGC -verbose There is a minimal stub defining a profiler interface: scala.tools.util.Profiling Then the yourkit wrapper implements that interface. Once your locker has been rebuilt once, you can do this: ant yourkit.run And it will build quick.lib/comp with profiling enabled, assuming it can find the necessary files. See the yourkit.init target for values to change: or ant -Dyourkit.home=/path/to/it might be enough. Review by dragos.

* ant, build.xml and classpath issues.Paul Phillips2010-11-163-41/+47
| | | | | | | | | | | | | | been ignoring their painstakingly set classpaths and using whatever they can find in the vicinity of the scala script, which works OK for pack but not so well for quick. I also added a build.xml feature so you can drop jars into a dir and have them automatically used everywhere. The directory is lib/extra. Pro tip: add lib/extra to .gitignore and put jars like yjp-controller-api-redist.jar in there. Closes #3706, no review.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Another exciting development in the world of -Y options which I and three other people will use. Today's is -Yrich-exceptions. Use it like so: SOURCEPATH=/path/to/src scalac -Yrich-exceptions a.scala In the repl, -Yrich-exceptions will cause lastException to be bound to an Exceptional instead of old rusty Throwable. That spins up new powers: scala> Nil.head [Nil.head] (List.scala:389) (access lastException for the full trace) scala> lastException.show /* The repl internal portion of the stack trace is elided. */ [Nil.head] 386: override def isEmpty = true 387: override def head: Nothing = 388: throw new NoSuchElementException("head of empty list") *389: override def tail: List[Nothing] = 390: throw new UnsupportedOperationException("tail of empty list") 391: // Removal of equals method here might lead to an infinite recursion similar to IntMap.equals. 392: override def equals(that: Any) = that match { [line0.<init>] (<console>:6) [line0.<clinit>] (<console>:-1) Also try "lastException.showTable" but this is getting a little long for more excerpt. No review.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some more work on options related to showing compiler structures during compilation. The pickler knew more than was healthy about things like compiler settings, so I let the pickler worry about pickling and moved that logic somewhere closer to the surface. Some convenience oriented tweaks to command line phase parsing. The end result is as follows (some output trimmed for brevity.) // dippy.scala class Dippy { def f[T <: Dippy](x: T) = (x, x) object DingusDippy extends util.Random { } } // className@phaseString should be reliably unambiguous % scalac -Xshow-class Dippy@typer,erasure,jvm dippy.scala <<-- class Dippy after phase 'typer' -->> Members (excluding Any/AnyRef unless overridden): final object DingusDippy extends object Dippy.this.DingusDippy def f[T <: Dippy](x: T): (T, T) <<-- class Dippy after phase 'erasure' -->> Members (excluding Any/AnyRef unless overridden): private lazy var DingusDippy$module: object Dippy#DingusDippy lazy val DingusDippy(): object Dippy#DingusDippy def f(x: Dippy): Tuple2 <<-- class Dippy after phase 'jvm' -->> Members (excluding Any/AnyRef unless overridden): protected var bitmap$0: Int private lazy var DingusDippy$module: object Dippy$DingusDippy lazy val DingusDippy(): object Dippy$DingusDippy def f(x: Dippy): Tuple2 No review.

| | | | | | | | | | | | | | | While investigating the cause of #3984, discovered that set hashcodes were being calculated like: elems map (_.hashCode) sum This looks totally correct, except that because of set+map semantics it drops all the duplicate hashcodes and therefore calculates the wrong sum anytime there are unequal elements with equal hashcodes. If we're married to the set+map semantics (and I don't know what could be done about it) I had better get a proper -Xlint going because this is one of those traps which shoots bees out of its mouth.

* This is work on -Ycheck:icode.Paul Phillips2010-11-0820-406/+492
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | distribution can now be built with that option, with or without optimization, and almost all tests cases can. (Those which can't are due to different -Ycheck: issues.) Major changes of interest are as follows: * LOAD_EXCEPTION and THROW are parameterized on the throwable symbol. * Does not squash all traits down to AnyRef, but instead deals with issues as they arise. By observation the cases where one needs a "Foo with Product" to manifest as both a "Foo" and a "Product" at different places are quite rare, so we need not throw out the whole baby. * Exception handlers now have positions. * The remaining checker failures removed, such as CALL_METHOD wanting to pop a value off the stack after calling a constructor. * Many multiply defined values such as REFERENCE(ObjectClass) put in one place (ICodes.scala) and reused. * -Ycheck:icode output (if also given -Ydebug) worthy of Michelangelo. Here is a class and the -Ycheck:icode -Ydebug output for f's block. class A { def f(x: Int, y: String) = try println(x + y.length) catch { case x: NullPointerException => () } } ** Checking Block 4 [S: 3, 2] [P: 1] <closed> 1-> REF(singleton class Predef) 3 + LOAD_MODULE object Predef 2-> INT 3 + LOAD_LOCAL(value x) 3-> REF(class String) 3 + LOAD_LOCAL(value y) 2<- REF(class String) 3 - CALL_METHOD java.lang.String.length (dynamic) 3-> INT 3 + CALL_METHOD java.lang.String.length (dynamic) 2<- INT 3 - CALL_PRIMITIVE(Arithmetic(ADD,INT)) 1<- INT 3 - """ 2-> INT 3 + CALL_PRIMITIVE(Arithmetic(ADD,INT)) 1<- INT 3 - BOX INT 2-> REF(class Integer) 3 + BOX INT 1<- REF(class Integer) 3 - CALL_METHOD scala.Predef.println (dynamic) 0<- REF(singleton class Predef) 3 - CALL_METHOD scala.Predef.println (dynamic) Review by dragos (I marked the specific spots I thought of interest with "PP to ID" which makes it sound like I'm talking to my primal self.

| | | | | | | | | | | Modified the lub calculation in TypeKinds to avoid the icode checker failures described in ticket #3872. This does not alter the compiler's lub calculation as I'd hoped because I could not figure out how to accomplish this without having unintended consequences. I think that either Symbol.isLess could be adjusted, or perhaps the implementation of spanningTypes, or other places... but it eluded me and I defer to the type wizards. No review.

| | | | | | | | | | | | A bit of -Xshow-class / -Xshow-object which didn't quite make the Global patch. Now type selections should do the right thing, e.g. scalac -Xshow-class Global#Run src/compiler/scala/tools/nsc/Global.scala will show you interesting things about Run.
