| | | | | | | | | | | | | | It's a Node-by-Node tour of the reifier's abilities and occasional foibles. That is one spectacularly attractive checkfile.

| | | | | | | | | | | | | | | | | | This allows us to deprecate external inheritances as a prelude to sealing a class, without enduring the warnings ourselved in interlude.

| | | | | | | | | | | | | | | | | | | | | | | | * Impossible (to the best of my knowledge) because LowPriorityImplicits is now defined in Predef.scala. Were I more sure, we could trip an assertion here, rather than the devWarning.
| * | | SI-7335 Don't import Predef._ in Predef.scalaJason Zaugg2013-04-083-16/+10

This didn't cause any harm, but in any case this commit restores the intended state of affairs. The change is visible only through logging; no test case is included. qbin/scalac -Ydebug -Ylog:all src/library/scala/Predef.scala -Ystop-after:typer 2>&1 | grep -i "Omitted import of Predef" [log namer] Omitted import of Predef._ for Predef.scala [log typer] Omitted import of Predef._ for Predef.scala A redundant override of `firstDefinesClassOrObject` is also removed.

More details in Lukas's comments in [2]. How did we bootstrap originally? Manually ordering source files, either in the Ant Build [1], or later in Global [2]. But neither mechanism remains in place (due, I suppose, to the difficulty in defending them with a test case.) The reordering in Global was removed in [3].

Currently, `supplementErrorMessage` does its working a try catch that only catches `Exception`.

The reason is that the tree passed for reification (see reifyTree at GetTrees.scala) must have not null tpe (see reifyBoundType at GenTrees.scala), which is not true in the case of ExistentialTypeTree. Why is it so? The tree passed to reifyTree was obtained in the reshape phase of reificationusing using original TypeTrees that reporesent pre- typer representation of a type. The problem is that original's tpe for ExistentialTypeTree is not set. So the solution to the issue is to create ExistentialTypeTree's original in a such way that is has actual tpe set.

Unfortunately this evaluation might fail if the mirror provided doesn't contain the classes being referred to. Therefore I think we should avoid evaluating type creators there. Note that failure of evaluation doesn't mean that there's something bad going on. When one creates a type tag, the correct mirror / classloader to interpret that tag in might be unknown (like it happens here). This is okay, and this is exactly what the 2.10.0-M4 refactoring has addressed. Something like `res2.typeTag[A].in(currentMirror)` should be okay.

Generated code of this kind should never be allowed. Three lines of documentation, duplicated 100 times, cannot masquerade as three hundred lines of documentation. If someone knows to look at the documentation of implicit ClassTags, they *already know* about implicit ClassTags. It is wherever "match" is documented which needs this information (and I am sure we can express it more clearly, given the luxury of only saying it once.) Documenting each ClassTag with the same boilerplate is comparable in utility to attaching such text to every Int. "An Int is a whole number within the range -2147483648 to 2147483647 inclusive. It's usually used to represent how many of something there are, such as '5 bunnies' or '3 witty commit messages', but you can store about anything in an Int if you can fit it into 32 bits." We don't do that, because you're expected to discover what an Int is in a manner which generalizes to all the Ints you may encounter. The situation with implicit ClassTags is immediately analogous.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the map is declared LinkedHashMap, which doesn't align with other caching maps that are cleared on every run. Linkedness is only needed to ensure deterministic order on the generated specialized classes. The same can be accomplished by sorting generated classes a-posteriori.

This type was used for the LabelDef generated in the TailCalls phase. But, the RHS of the method still contains types that refer to the original parmameter symbol. Spurious type errors ensued. I've spent a good chunk of time pursuing a more principled fix, in which we keep the symbols in the tree in sync with those in the MethodType. You can relive the procession of false dawns: https://github.com/scala/scala/pull/2248 Ultimately that scheme was derailed by a mismatch between the type parameter `T` and the skolem `T&` in the example below. trait Endo[A] { def apply(a: => A): A } class Test { def foo[T] = new Endo[(T, Unit)] { def apply(v1: => (T, Unit)) = v1 // no bridge created } } Interestingly, by removing the caching in SingleType, I got past that problem. But I didn't characterize it further. This commit sets asides the noble goal of operating in the world of types, and sledgehammers past the crash by casting the arguments to and the result of the label jump generated in TailCalls.

This is preferable to having the tree transformer overwrite the result of the info transformer, as used to be the case after my previous work on SI-6135 / 493197fc.

What this commit does is bypass the creation and composition of iterators entirely in favor of applying foreach to walking the tree. The important lesson of a bug like this: the occurrence depends on the existence of multiple implementations of basic structures like Trees. For each redundant implementation, scrutiny and testing are divided and "bug diversity" is increased. We should labor hard to structure collections in such a way that people have no good reason not to take advantage of the basic and hopefully battle-tested logic - especially when those people are us. I hope to remove util.TreeSet entirely. Until then, here is the impact of this commit on the time to compile a piece of generated test code. % time scalac3 ./target/generated/src.scala Mar 28 13:20:31 [running phase parser on src.scala] ...
