It's redundant. Only V8Parameter will work. - Rename V8Parameter to V8GenericString, because it's an adapter class for String and AtomicString. 700497 3 159618 abarth 2012-08-20 23:13:32 -0700 Comment on attachment 159618 Patch View in context: https://bugs.webkit.org/attachment.cgi?id=159618&action=review > Source/WebCore/bindings/v8/V8StringResource.cpp:35 > + I'd remove this blank line. > Source/WebCore/bindings/v8/V8StringResource.cpp:52 > + String result = String::createUninitialized(length, buffer); Does this really use int as the type for length? > Source/WebCore/bindings/v8/V8StringResource.cpp:75 > + String tmp = String::createUninitialized(length, buffer); tmp -> string ? > Source/WebCore/bindings/v8/V8StringResource.cpp:88 > + int length = v8String->Length(); Oh, V8 uses int for the length of a string? > Source/WebCore/bindings/v8/V8StringResource.cpp:91 > + return StringImpl::empty(); Is this ok for background threads?

Given that this is not a fast path of v8String(), it would be OK to create String("") every time. 701559 10 159852 webkit.review.bot 2012-08-21 21:42:01 -0700 Comment on attachment 159852 patch for landing Clearing flags on attachment: 159852 Committed r126262: <http://trac.webkit.org/changeset/126262> 701560 11 webkit.review.bot 2012-08-21 21:42:07 -0700 All reviewed patches have been landed.
