…ative ID generation (#55183) ### What problem does this PR solve? Problem Summary: `Replace Math.abs() with bitwise AND operation in genIdByName() method` problem: - Math.abs(Long.MIN_VALUE) returns Long.MIN_VALUE (still negative) due to overflow - This violates the requirement that external db/table IDs must be >= 0 - Could cause issues in DescriptorTable.toThrift() as mentioned in comments fix: - Use bitwise AND with Long.MAX_VALUE to clear the sign bit - Guarantees non-negative result in range [0, Long.MAX_VALUE] - Better performance than Math.abs() conditional check ### Release note None ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [ ] Regression test - [ ] 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. - [ ] Yes. <!-- Explain the behavior change --> - Does this need documentation? - [ ] No. - [ ] Yes. <!-- Add document PR link here. eg: apache/doris-website#1214 --> ### 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 -->
