Stephen0421 opened a new pull request, #9223:
URL: https://github.com/apache/paimon/pull/9223
### Purpose
Harden BLOB file metadata parsing against corrupt or truncated footer and
index data.
This change:
- Validates the minimum footer size and index boundaries before seeking or
allocating memory.
- Rejects malformed compressed indexes with a descriptive `IOException`.
- Validates record-length sentinels, minimum record length, and the total
indexed data size.
- Validates selection cardinality and selected record positions.
- Preserves the existing lazy payload-reading behavior.
### Test
- Added `BlobFileMetaTest` covering:
- Truncated files.
- Invalid index lengths and malformed indexes.
- Unsupported versions.
- Invalid record lengths and mismatched data-region sizes.
- NULL and placeholder sentinels.
- Empty, non-contiguous, and out-of-range selections.
