Rhino 1.7.11

Table of contents

This release includes implementations of a number of missing JavaScript language features, including:

  • Improvement to the accuracy and reliability of the parser and its associated AST.
  • The Map, Set, WeakMap, and WeakSet classes.
  • More Array functions, including from, of, fill, keys, values, entries, and copyWithin.
  • Many more Math methods.
  • More Object functions, including seal and freeze.
  • Many other bug fixes, as shown below.

In general, Rhino’s philosophy for new features and changes is to follow the ECMAScript spec, but to use the “language version” on the Context class when backward compatibility would be broken.

For example, the Array.prototype.concat function in older versions of Rhino would treat any input value as “spreadable” if it has the same constructor as Array. ECMAScript now says clearly that this should only happen if the “isConcatSpreadable” symbol is present. In this release, the old behavior is disable when the language level is at least the “ES6” level (Context.VERSION_ES6, or 200).

Developers working on new code will be happier if they set the language level to CONTEXT.VERSION_ES6, or use the “-version 200” flag to the command line tool.

A future release will change the default language version of the command line tool.

This release contains contributions from 15 developers. Thanks for all your hard work!

  • and some more; now we are at 51093
  • Use as many test262 tests as possible to check our quality
  • implement missing Math functions
  • disable some slow tests
  • Support for arguments object as TypedArray constructor argument this is the same as #297 but includes a simple test.
  • fix issue 437
  • use the system line separator for code generation
  • remove work around for 437
  • fix #449 also and remove the work around from EqualObjectGraphs
  • add @Override and some more cleanup

  • avoid star imports across the codebase
  • fall back to the interpreter if the byte code generation fails
  • fix serialization for NativeMap, NativeSet, NativeWeakMap, and NativeWeakSet
