" Commitd0f9e00changed the representation of the gc_clock::duration from int32_t to int64_t. Mutation hashing uses appending_hash<gc_clock::time_point>, which by default feeds duration::count() into the hasher. duration::rep changed from int32_t to int64_t, which changes the value of the hash. This affects schema digest and query digests, resulting in mismatches between nodes during a rolling upgrade. Fixes #4460. Refs #4485. " * tag 'fix-gc_clock-digest-v2.1' of github.com:tgrabiec/scylla: tests: Add test which verifies that schema digest stays the same tests: Add sstables for the schema digest test schema_tables, storage_service: Make schema digest insensitive to expired tombstones in empty partition db/schema_tables: Move feed_hash_for_schema_digest() to .cc file hashing: Introduce type-erased interface for the hasher hashing: Introduce C++ concept for the hasher hashers: Rename hasher to cryptopp_hasher gc_clock: Fix hashing to be backwards-compatible (cherry picked from commit82b91c1511)
