Bug 1484496: Part 4a - Add JS iterator support to nsISimpleEnumerator. r=mccr8 This patch adds simple stubs to convert between the nsISimpleEnumerator iteration protocol and the JS iteration protocol. Each iterable object is required to have an @@iterator method which returns an object implementing the iterator protocol. The later objects, by convention, also have such a method which returns the object itself. This patch adds both a @@iterator() and entries() methods to nsISimpleEnumerator. The former returns an iterator which returns plain nsISupports objects. The latter accepts an IID and queries each element to that IID before returning it. If any element fails to query, the error is propagated to the caller.

Bug 1214364 part 4. Only output full-featured Init methods for dictionaries that need them. r=peterv Dictionaries that we never initialize with JS values don't need a full-featured Init() method. Instead, we output a cut-down Init() method that doesn't even take a JSContext and Value as argument, and skips as much work as it can. It uses constant-false for "is the value present?", but also, to avoid compilation errors due to use of `cx` and `val` in now-dead conversion code, it tells the native-to-JS conversion machinery that the value is always missing, which lets it skip most of the the work it would normally try to do and just output initialization to the default value. We only need to do this for members that have default values; the others either remain no-passed or are required members with no default-initialization behavior. This saves about 330KB of codesize on Linux64 without PGO and 285KB with PGO. Differential Revision: https://phabricator.services.mozilla.com/D48007 --HG-- extra : moz-landing-system : lando
