This adds 3 new log fields for transaction output (since collapsed forwarding is transaction based) * crra - The number of read retry attempts for this transaction. If no CF has been done (it has not attempted a write) then this is just the read lock contention. If a write has been attempted then this value gets reset to 0 as it attempts more reads post-write-fail. * cwra - The number of write retry attempts. This will be either the number based on write lock contention, or it can be the max-write-retries+1. If it is max+1 that means that we have hit the max attempts because the lock was being held by another writer and so this transaction fell back to read retries and attempted to be collapsed * cccs - Collapsed connection success. This is just 0/1. 0 if a connection either was not attempted to be collapsed, did not need to be collapsed, or it was attempted but ended up going to the origin anyway. If it is 1 then this transaction hit its max write retries but successfully got a cache HIT during its read retries post-write-failure ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
