Azat Khuzhin 3a72e1c12a Add checksum for extra info/query in distributed sends ... This extras includes: - server revision - query settings - query Otherwise the code can try to interpret data, and got for instance std::length_error exception, which is not catched (to mark the part as broken). Also this will protect from the corruptions on disk. And add a simple test, since dbms/tests/integration/test_insert_into_distributed too complex. Also simplify the code by using readStringBinary() over readVarUInt()+b.readStrict() (this also gains additional checks that string is not bigger then 1GB). Refs: #4852 (8ef7f3589a) v2: avoid ABI breakage (suggested by @vitlibar) v3: minor code fixes (suggested by @vitlibar) and as a consequence clang-8 build fix v4: drop DBMS_MIN_REVISION_WITH_EXTRAS_CHECKSUM_IN_DIST_BATCH and also revert some renames to make the patch cleaner		2019-12-04 22:54:38 +03:00
