sdong 4e00748098 Fix a bug in hash linked list (#10401) ... Summary: In hash linked list, with a bucket of only one record, following sequence can cause users to temporarily miss a record: Thread 1: Fetch the structure bucket x points too, which would be a Node n1 for a key, with next pointer to be null Thread 2: Insert a key to bucket x that is larger than the existing key. This will make n1->next points to a new node n2, and update bucket x to point to n1. Thread 1: see n1->next is not null, so it thinks it is a header of linked list and ignore the key of n1. Fix it by refetch structure that bucket x points to when it sees n1->next is not null. This should work because if n1->next is not null, bucket x should already point to a linked list or skip list header. A related change is to revert th order of testing for linked list and skip list. This is because after refetching the bucket, it might end up with a skip list, rather than linked list. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10401 Test Plan: Run existing tests and make sure at least it doesn't regress.
