143449 2015-04-06 11:52:17 -0700 Simplify ownership model of RefCounter::Count 2015-04-06 12:17:13 -0700 1 1 1 Unclassified WebKit Web Template Framework 528+ (Nightly build) Unspecified Unspecified NEW P2 Normal --- 1 barraclough barraclough benjamin cmarcelo commit-queue oldest_to_newest 1083128 0 barraclough 2015-04-06 11:52:17 -0700 Currently the count manipulated by ref/deref does not fully determine the lifetime of the object - the object is either kept alive if the refcount is non-zero, or if the owner RefCounter is still alive (separately determined). Make the object lifetime simpler by making it purely determined by the RefCount (and as such RefCounter::Count can just become a regular RefCounted). Add a new variable to track the counter value. This patch is a step towards adding a token type that doesn't increment the count (to be able to avoid bogus churn & keep the count accurate). 1083130 1 250216 barraclough 2015-04-06 12:01:14 -0700
