### What problem does this PR solve? Issue Number: None Related PR: #44901 Problem Summary: 1. `array_shuffle` now rejects a non-constant seed, which was silently ignored for every row but the first one of each block. 2. The seed now uses all 64 bits (`std::mt19937_64`), so any BIGINT seed works, including a negative one, which failed with an out-of-range error since #44901. 3. Every row is now shuffled on its own, so a constant array no longer gets the same order on every row, and blocks without a seed no longer repeat each other. doc: apache/doris-website#4176 ### Release note `array_shuffle` / `shuffle` rejects a non-constant seed, uses all 64 bits of the seed (so the order for a given seed changes), and shuffles every row on its own. ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [x] Regression test - [x] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test. Explain why: - [ ] This is a refactor/code format and no logic has been changed. - [ ] Previous test can cover this change. - [ ] No code files have been changed. - [ ] Other reason <!-- Add your reason? --> - Behavior changed: - [ ] No. - [x] Yes. See the three points above. - Does this need documentation? - [ ] No. - [x] Yes. <!-- apache/doris-website PR link to be added --> ### Check List (For Reviewer who merge this PR) - [ ] Confirm the release note - [ ] Confirm test cases - [ ] Confirm document - [ ] Add branch pick label <!-- Add branch pick label that this PR should merge into --> --------- Co-authored-by: Claude Opus 5.5 (1M context) <[email protected]>
