From 05960b5ddb026763719a37bd66539a350fcd2fad Mon Sep 17 00:00:00 2001 From: Rene Cannao Date: Thu, 27 Nov 2025 18:05:05 +0000 Subject: [PATCH 1/9] Fix issue 4855: Reset affected_rows to 0 for DDL queries in Admin interface Problem: When executing DDL queries (CREATE TABLE, DROP TABLE, VACUUM, etc.) in the ProxySQL Admin interface after DML operations, the affected rows count from the previous DML operation was incorrectly reported instead of 0. This is because SQLite's sqlite3_changes() function doesn't reset the counter for DDL statements. Root Cause: SQLite's sqlite3_changes() returns the number of rows affected by the most recent INSERT, UPDATE, or DELETE statement. For DDL statements that don't modify rows, SQLite doesn't reset this counter, so it continues to return the value from the last DML operation. Solution: - Added is_ddl_query_without_row_changes() function to identify DDL queries that don't affect row counts - Modified both execute_statement() and execute_statement_raw() in SQLite3DB to return 0 for affected_rows when executing DDL queries - The fix ensures that affected_rows is reset to 0 for: CREATE, DROP, ALTER, TRUNCATE, VACUUM, REINDEX, ANALYZE, CHECKPOINT, PRAGMA, BEGIN, COMMIT, ROLLBACK, SAVEPOINT, RELEASE, EXPLAIN Testing: - Created and ran comprehensive tests for DDL detection function - Verified build completes successfully - Confirmed the fix correctly identifies DDL vs DML queries Impact: This fix resolves the issue where Admin interface incorrectly shows affected rows for DDL operations, improving the accuracy and reliability of the ProxySQL Admin interface.

This approach was brittle and could miss edge cases like commented queries or complex statements. SOLUTION: Instead of detecting DDL queries, use sqlite3_total_changes64() to measure the actual change count before and after each query execution. The difference between total_changes before and after represents the true affected rows count for the current query, regardless of query type. CHANGES: - Added proxy_sqlite3_total_changes64 function pointer and initialization - Rewrote execute_statement() and execute_statement_raw() to use total_changes difference approach - This automatically handles all query types (DDL, DML, comments, etc.) - Added comprehensive TAP test covering INSERT, CREATE, DROP, VACUUM, UPDATE, and BEGIN operations BENEFITS: - More robust and accurate than DDL detection approach - Handles edge cases like commented queries automatically - No maintenance overhead for new query types - Simpler and cleaner implementation - Still fixes both Admin interface and SQLite3 Server This approach is mathematically sound: affected_rows = total_changes_after - total_changes_before, which gives the exact number of rows changed by the current query execution.
