72063 2011-11-10 14:52:03 -0800 [MutationObservers] V8 bindings don't properly wrap all calls into JS 2011-11-30 04:57:32 -0800 1 1 1 Unclassified WebKit DOM 528+ (Nightly build) Unspecified Unspecified RESOLVED FIXED P2 Normal --- 72181 72422 72645 68729 1 adamk adamk abarth antonm fishd japhet pfeldman rafaelw webkit.review.bot oldest_to_newest 500317 0 adamk 2011-11-10 14:52:03 -0800 V8Proxy::didLeaveScriptContext claims to run whenever the outermost script invocation exits, but it's broken in two ways: - Not all script calls go through V8Proxy::callFunction (e.g., they call the v8::Function::Call, or V8Proxy::instrumentedCallFunction). - V8Proxy::m_recursion (used to count the number of nested invocations) is per-frame, which is incorrect. It should probably just be a static. So we need a replacement for m_recursion and didLeaveScriptContext. Where these live is up in the air (abarth suggests that V8Proxy is not the right place to live). 501121 1 adamk 2011-11-11 14:46:56 -0800 Per :dslomov, m_recursion should live in V8BindingPerIsolateData. 511164 2 117062 rafaelw 2011-11-29 15:42:02 -0800 Created attachment 117062 Patch 511167 3 rafaelw 2011-11-29 15:49:14 -0800 Note that this patch has the effect that old callers of callFunctionWithoutFrame now also check the max recursion depth, and invoke didLeaveScriptContext. Existing callers of instrumentedCallFunction get both of these PLUS (at no added cost) the V8GCController::checkMemoryUsage(). 511642 4 117062 webkit.review.bot 2011-11-30 04:57:27 -0800 Comment on attachment 117062 Patch Clearing flags on attachment: 117062 Committed r101490: <http://trac.webkit.org/changeset/101490> 511643 5 webkit.review.bot 2011-11-30 04:57:32 -0800 All reviewed patches have been landed.
