Summary: Fixes Issue https://github.com/facebook/rocksdb/issues/7497 When allow_data_in_errors db_options is set, log error key details in `ParseInternalKey()` Have fixed most of the calls. Have few TODOs still pending - because have to make more deeper changes to pass in the allow_data_in_errors flag. Will do those in a separate PR later. Tests: - make check - some of the existing tests that exercise the "internal key too small" condition are: dbformat_test, cuckoo_table_builder_test - some of the existing tests that exercise the corrupted key path are: corruption_test, merge_helper_test, compaction_iterator_test Example of new status returns: - Key too small - `Corrupted Key: Internal Key too small. Size=5` - Corrupt key with allow_data_in_errors option set to false: `Corrupted Key: '<redacted>' seq:3, type:3` - Corrupt key with allow_data_in_errors option set to true: `Corrupted Key: '61' seq:3, type:3` Pull Request resolved: https://github.com/facebook/rocksdb/pull/7515 Reviewed By: ajkr Differential Revision: D24240264 Pulled By: ramvadiv fbshipit-source-id: bc48f5d4475ac19d7713e16df37505b31aac42e7
