* SI-8151 Remove -Yself-in-annots and associated implementationJason Zaugg2014-01-151-1/+1
| | | | | | | | | | | | | | | This experimental option typechecked arguments of annotations with an injected value in scope named `self`: @Foo(self.foo < 1) This has been slated for removal [1] for some time. This commit removes it in one fell swoop, without any attempt at source compatibility with code that constructs or pattern matches on AnnotatedType.

* Commenting out unused members.Paul Phillips2012-11-191-10/+10
| | | | | | | | | | | | | | | | | | I want to get this commit into the history because the tests pass here, which demonstrates that every commented out method is not only unnecessary internally but has zero test coverage. Since I know (based on the occasional source code comment, or more often based on knowing something about other source bases) that some of these can't be removed without breaking other things, I want to at least record a snapshot of the identities of all these unused and untested methods. This commit will be reverted; then there will be another commit which removes the subset of these methods which I believe to be removable. The remainder are in great need of tests which exercise the interfaces upon which other repositories depend.
* Removed unused imports.Paul Phillips2012-11-061-2/+0
| | | | | | | | | A dizzying number of unused imports, limited to files in src/compiler. I especially like that the unused import option (not quite ready for checkin itself) finds places where feature implicits have been imported which are no longer necessary, e.g. this commit includes half a dozen removals of "import scala.language.implicitConversions".

* | Remove unused private members.Paul Phillips2012-11-011-2/+0
| | | | | | | | | | | | | | | | | | That's a lot of unused code. Most of this is pure cruft; a small amount is debugging code which somebody might want to keep around, but we should not be using trunk as a repository of our personal snippets of undocumented, unused, unintegrated debugging code. So let's make the easy decision to err in the removing direction. If it isn't built to last, it shouldn't be checked into master.

* More relative path elimination.Paul Phillips2012-09-151-1/+1
| | | | | | | | | | | | | | | | Some names I missed in 55b609458fd . How one might know when one is done: mkdir scratch && cd scratch mkdir annotation beans collection compat concurrent io \ math parallel ref reflect runtime scala sys testing \ text tools util xml scalac $(find ../src/library -name '*.scala') Until recently that would fail with about a billion errors. When it compiles, that's when you're done. And that's where this commit takes us, for src/library at least.
* Eliminate breaking relative names in source.Paul Phillips2012-09-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These things are killing me. Constructions like package scala.foo.bar.baz import foo.Other DO NOT WORK in general. Such files are not really in the "scala" package, because it is not declared package scala package foo.bar.baz And there is a second problem: using a relative path name means compilation will fail in the presence of a directory of the same name, e.g. % mkdir reflect % scalac src/reflect/scala/reflect/internal/util/Position.scala src/reflect/scala/reflect/internal/util/Position.scala:9: error: object ClassTag is not a member of package reflect import reflect.ClassTag ^ src/reflect/scala/reflect/internal/util/Position.scala:10: error: object base is not a member of package reflect import reflect.base.Attachments ^ As a rule, do not use relative package paths unless you have explicitly imported the path to which you think you are relative. Better yet, don't use them at all. Unfortunately they mostly work because scala variously thinks everything scala.* is in the scala package and/or because you usually aren't bootstrapping and it falls through to an existing version of the class already on the classpath. Making the paths explicit is not a complete solution - in particular, we remain enormously vulnerable to any directory or package called "scala" which isn't ours - but it greatly limts the severity of the problem.

* The new reflectionEugene Burmako2012-06-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A must read: "SIP: Scala Reflection": https://docs.google.com/document/d/1Z1VhhNPplbUpaZPIYdc0_EUv5RiGQ2X4oqp0i-vz1qw/edit Highlights: * Architecture has undergone a dramatic rehash. * Universes and mirrors are now separate entities: universes host reflection artifacts (trees, symbols, types, etc), mirrors abstract loading of those artifacts (e.g. JavaMirror loads stuff using a classloader and annotation unpickler, while GlobalMirror uses internal compiler classreader to achieve the same goal). * No static reflection mirror is imposed on the user. One is free to choose between lightweight mirrors and full-blown classloader-based mirror (read below). * Public reflection API is split into scala.reflect.base and scala.reflect.api. The former represents a minimalistic snapshot that is exactly enough to build reified trees and types. To build, but not to analyze - everything smart (for example, getting a type signature) is implemented in scala.reflect.api. * Both reflection domains have their own universe: scala.reflect.basis and scala.reflect.runtime.universe. The former is super lightweight and doesn't involve any classloaders, while the latter represents a stripped down compiler. * Classloader problems from 2.10.0-M3 are solved. * Exprs and type tags are now bound to a mirror upon creation. * However there is an easy way to migrate exprs and type tags between mirrors and even between universes. * This means that no classloader is imposed on the user of type tags and exprs. If one doesn't like a classloader that's there (associated with tag's mirror), one can create a custom mirror and migrate the tag or the expr to it. * There is a shortcut that works in most cases. Requesting a type tag from a full-blown universe will create that tag in a mirror that corresponds to the callsite classloader aka `getClass.getClassLoader`. This imposes no obligations on the programmer, since Type construction is lazy, so one can always migrate a tag into a different mirror. Migration notes for 2.10.0-M3 users: * Incantations in Predef are gone, some of them have moved to scala.reflect. * Everything path-dependent requires implicit prefix (for example, to refer to a type tag, you need to explicitly specify the universe it belongs to, e.g. reflect.basis.TypeTag or reflect.runtime.universe.TypeTag). * ArrayTags have been removed, ConcreteTypeTag have been renamed to TypeTags, TypeTags have been renamed to AbsTypeTags. Look for the reasoning in the nearby children of this commit. Why not in this commit? Scroll this message to the very bottom to find out the reason. * Some of the functions have been renamed or moved around. The rule of thumb is to look for anything non-trivial in scala.reflect.api. Some of tree build utils have been moved to Universe.build. * staticModule and staticClass have been moved from universes to mirrors * ClassTag.erasure => ClassTag.runtimeClass * For the sake of purity, type tags no longer have erasures. Use multiple context bounds (e.g. def foo[T: ru.TypeTag : ClassTag](...) = ...) if you're interested in having both erasures and types for type parameters. * reify now rolls back macro applications. * Runtime evaluation is now explicit, requires import scala.tools.reflect.Eval and scala-compiler.jar on the classpath. * Macro context now has separate universe and mirror fields. * Most of the useful stuff is declared in c.universe, so be sure to change your "import c.universe._" to "import c.mirror._". * Due to the changes in expressions and type tags, their regular factories are now really difficult to use. We acknowledge that macro users need to frequently create exprs and tags, so we added old-style factories to context. Bottom line: almost always prepend Expr(...)/TypeTag(...) with "c.". * Expr.eval has been renamed to Expr.splice. * Expr.value no longer splices (it can still be used to express cross-stage path-dependent types as specified in SIP-16). * c.reifyTree now has a mirror parameter that lets one customize the initial mirror the resulting Expr will be bound to. If you provide EmptyTree, then the reifier will automatically pick a reasonable mirror (callsite classloader mirror for a full-blown universe and rootMirror for a basis universe). Bottom line: this parameter should be EmptyTree in 99% of cases. * c.reifyErasure => c.reifyRuntimeClass. Known issues: * API is really raw, need your feedback. * All reflection artifacts are now represented by abstract types. This means that pattern matching against them will emit unchecked warnings. Adriaan is working on a patch that will fix that. WARNING, FELLOW CODE EXPLORER! You have entered a turbulence zone. For this commit and its nearby parents and children tests are not guaranteed to work. Things get back to normal only after the "repairs the tests after the refactoring spree" commit. Why so weird? These twentish changesets were once parts of a humongous blob, which spanned 1200 files and 15 kLOC. I did my best to split up the blob, so that the individual parts of the code compile and make sense in isolation. However doing the same for tests would be too much work.

Would prefer to bake a little longer, but, scala days. More elaboration to come.
