| | | | | | | | | | | | ... instead of scala.collection.mutable.StringBuilder to benefit from JVM optimizations. Unfortunately primitives are already boxed in erasure when they end up in this part of the backend.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This additionally fixes both SI-8648 and SI-9564. Added documentation to Builder to clarify that in general Builders are NOT reusable. Altered implementation of GrowingBuilder to use Growable instance's clear (not valid for a reusable builder, but this one isn't reusable). Added a new marker trait ReusableBuilder that specifies that these builders should be reusable. This trait overrides the clear and result methods while leaving them abstract in order to supply appropriate scaladoc. Made all Array builders Reusable in all cases (by setting capacity to 0 if the original array is returned). (Fixed a poor implmentation of Array[Unit] builder along the way.) Documented which other builders were already reusable (maps, sets, Vector, LazyBuilder, StringBuilder, ListBuffer, etc.).

| * | | SI-9398 Treat case classes as one-element ADTs for analysisJason Zaugg2016-01-2915-12/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, exhaustivity analysis only runs for scrutinees with a sealed type. This commit treats any case class as a one-element, sealed type to enable additional analysis, such as in the new test case.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hash consing of trees within pattern match analysis was broken, and considered `x1.foo#1` to be the same tree as `x1.foo#2`, even though the two `foo`-s referred to different symbols. The hash consing was based on `Tree#correspondsStructure`, but the predicate in that function cannot veto correspondance, it can only supplement the default structural comparison. I've instead created a custom tree comparison method for use in the pattern matcher that handles the tree shapes that we use.

|/ / | | | | | | | | | | | | | | | | Before this commit, multiple invocations of universe.showRaw used a shared weak map that caches footnotes. If the two printed objects have equal components printed as footnotes, e.g., an equal TypeRef, the result of the second invocation depends on whether the object has been collected (and removed from the weak map) or not.

| | | | | | | | | | | | Just like `ArraySeq`, `ArrayBuffer` and all other collections that use an array as underlying data structure, `ArrayStack` should also be an instance of `IndexedSeq` and `IndexedSeqOptimized`. As expected by both of the traits, `ArrayStack` has constant-time random element access and length computation.

| * | | | SI-8700 Exhaustiveness warning for enums from Java sourceSimon Ochsenreither2016-01-1414-13/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, the warning was only emitted for enums from Java class files. This commit fixes it by - aligning the flags set in JavaParsers with the flags set in ClassfileParser (which are required by the pattern matcher to even consider checking exhaustiveness) - adding the enum members as childs to the class holding the enum as done in ClassfileParser so that the pattern matcher sees the enum members when looking for the sealed children of a type

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit addresses the need for an improved mobile viewing experience. Specifically it introduces CSS media queries to adjust sizing and indentation of elements on mobile devices. This includes the following changes: - replace absolute font sizing with relative font sizing - fix font-resizing issues for mobile by fixing viewport - hide related links when viewport too small - fix missing trigram from heaven on Android - remove indentation on annotations e.g. `@throws` and place associated text on a separate line - fix bottom scoll-bar appearing on code-snippets - add spacing between entity icons in browser - add dynamic top offset for entity description - fix long entity names corrupting style - remove "EXPERIMENTAL" button from shortcomment divs on mobile
