Add a faster API for creating v8::Integer objects · 06360928

danno@chromium.org authored Oct 19, 2012

In WebKit, we have a small integer cache because calling v8::Integer::New is
slow. This patch adds a faster API for creating integers that requires the
caller to supply the v8::Isolate, saving us the work of looking up the isolate
in thread-local storage.

Add an API for enumerating persistent handles · 9dc2c5b8

svenpanne@chromium.org authored Oct 18, 2012

This API lets the embedder enumerate handles that have class ids. WebKit will
use this feature during garbage collection to compute object groups for DOM
nodes. Previously, we kept a list of DOM nodes on the WebKit side, but that
list is redundant with the global handles list in V8.
