…1037 Backport ClickHouse#121037 to 26.3: Fix segmentation fault in `RefreshTask::startup()` racing a parallel shutdown
…rted columns when a field type is unsupported
`croaring` v5.1.1 was backported to release branches that are still built with clang-21. clang-21 MemorySanitizer checks the value instead of the shadow of the index operand of AVX-512 `vpermi2var` intrinsics (llvm/llvm-project#148785, fixed in clang-22), so `avx512_emit_unique16` (reached from `MergeTextIndexesTask::executeStep`) triggers `use-of-uninitialized-value` on runners with AVX-512 VBMI2, and the server dies in every MSan stateless job. Define `CROARING_COMPILER_SUPPORTS_AVX512=0` for MSan builds; croaring's `isadetection.h` honours a predefined value. Non-MSan builds are unchanged.

Antalya sends single-shard `remote` requests as initial queries. After granting `SELECT`, both network and local execution succeed, with default or explicit credentials. Update the reference and comments. Manually verified that missing privileges and restrictive row policies still deny all four variants. Production behavior is unchanged.

Backported ClickHouse#110757, which is a 26.4 backport of ClickHouse#100849. Here's the Codex summary of the reason: The Protobuf recovery tests fail consistently in ASan and UBSan because 26.3 caches schema importers only by directory and reuses descriptors by message name. Different schemas defining Decision: backport upstream PR ClickHouse#100849, including the cache-key fix, |
