Version 1.3.6
Browse files Browse the repository at this point in the history 
Add support for forceful termination of JavaScript execution.

Add low memory notification to the API. The embedding host can signal a low memory situation to V8.

Changed the handling of global handles (persistent handles in the API sense) to avoid issues regarding allocation of new global handles during weak handle callbacks.

Changed the growth policy of the young space.

Fixed a GC issue introduced in version 1.3.5.

2009-10-07: Version 1.3.14

Added GetRealNamedProperty to the API to lookup real properties
located on the object or in the prototype chain skipping any
interceptors.

Fix the stack limits setting API to work correctly with threads. The
stack limit now needs to be set to each thread thich is used with V8.

Remove the high-priority flag from IdleNotification()

Ensure V8 is initialized before locking and unlocking threads.

Implemented a new JavaScript minifier for compressing the source of
the built-in JavaScript. This Remove non-Open Source code from Douglas
Crockford from the project.

Added a missing optimization in StringCharAt.

Fixed some flaky socket tests.

Change by Alexander Botero-Lowry to fix profiler sampling on FreeBSD
in 64-bit mode.

Fixed memory leaks in the thread management code.

Fixed the result of assignment to a pixel array. The assigned value
is now the result.

Error reporting for invalid left-hand sides in for-in statements, pre-
and postfix count expressions, and assignments now matches the JSC
behavior in Safari 4.

Follow the spec in disallowing function declarations without a name.

Always allocate code objects within a 2 GB range. On x64 architecture
this is used to use near calls (32-bit displacement) in Code objects.

Optimized array construction ported to x64 and ARM architectures.

[ES5] Changed Object.keys to return strings for element indices.


2009-09-23: Version 1.3.13

Fixed uninitialized memory problem.
