Comment on attachment 211358 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=211358&action=review > Source/WTF/ChangeLog:8 > + Allow rehahsing to track a hash bucket and return the new pointer to it, thus avoiding typo: rehashing > Source/WTF/wtf/HashTable.h:-940 > - // FIXME: This makes an extra copy on expand. Probably not that bad since > - // expand is rare, but would be better to have a version of expand that can > - // follow a pivot entry and return the new position. You fixed this FIXME!
