when evacuate oldbucket, go will migrate the data to a new position. and i found it used X and Y as two bucket where Xi equal the old index in h.oldbuckets and Yi equal Xi plus newbit
suppose the length of oldbuckets is 8 ， and the hash of a key is 13 (just a example), then it will be put in the 5. Now, the buckets grow to 16, it should be put in the 13. I think. but i found the code below. https://github.com/golang/go/blob/6732fcc06df713fc737cee5c5860bad87599bc6d/src/runtime/hashmap.go#L1115 useX will be true, if so, the 13 will be put in the 5 still, then i can't understand it. Did i miss something ? go 1.9 -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
