thswlsqls opened a new pull request, #39363:
URL: https://github.com/apache/shardingsphere/pull/39363

   Fixes #39360.
   
   Changes proposed in this pull request:
     - Remove the `ADDRESS_RANDOM_REPLACE` lexer token from 
`features/mask/distsql/parser/src/main/antlr4/imports/mask/Keyword.g4`; no 
parser rule references it and no matching `MaskAlgorithm` exists in the 
repository.
     - The token preceded `IDENTIFIER_`, so `address_random_replace` was 
rejected as a mask rule name, column name or database name. Removing it lets 
those words fall back to `IDENTIFIER_`, the same intended result as #39012.
     - Add `MaskDistSQLStatementVisitorTest`, mirroring 
`ShardingDistSQLStatementVisitorTest`; three cases cover the previously 
rejected statements and one guards the existing `GENERIC_TABLE_RANDOM_REPLACE` 
built-in type against regression.
     - This completes the built-in mask algorithm cleanup requested in #24847: 
#24848 removed only the `BaseRule.g4` alternative, and #28071 removed both 
files for the five sibling algorithms.
     - No documentation update is required: `reserved-word.en.md` and 
`reserved-word.cn.md` list only `MASK` and `COLUMNS` under MASK, so this token 
was never a documented reserved word — unlike #39012, whose tokens were 
documented and updated together.
     - Other unused tokens remain in the feature DistSQL grammars. They have no 
comparable removal history and are left for separate assessment.
