From f5128d76d98c3fbf1c549ca8a8c1272b3554350f Mon Sep 17 00:00:00 2001 From: Rene Cannao Date: Fri, 28 Nov 2025 03:00:13 +0000 Subject: [PATCH] Fix TAP test for issue 4855 affected rows DDL bug Improve the TAP test to be SQLite-compatible and comprehensive: - Remove TRUNCATE operations (not supported by SQLite) - Use individual DROP TABLE statements instead of multi-table DROP - Add VACUUM test to verify DDL affected rows are 0 - Update test plan to match actual number of assertions (14) - Use temporary tables instead of configuration tables - Test all major DDL operations: CREATE, DROP, ALTER, VACUUM - Test all major DML operations: INSERT, UPDATE, DELETE - Verify affected rows are correctly calculated for all query types - Add test for commented DDL queries - Include comprehensive cleanup with proper error handling The test now accurately verifies that the sqlite3_total_changes64() difference approach correctly fixes the affected rows calculation for both DDL and DML operations. --- .../reg_test_4855_affected_rows_ddl-t.cpp | 141 +++++++++++------- 1 file changed, 85 insertions(+), 56 deletions(-) diff --git a/test/tap/tests/reg_test_4855_affected_rows_ddl-t.cpp b/test/tap/tests/reg_test_4855_affected_rows_ddl-t.cpp index 638ad1a30..f2baab5f9 100644 --- a/test/tap/tests/reg_test_4855_affected_rows_ddl-t.cpp +++ b/test/tap/tests/reg_test_4855_affected_rows_ddl-t.cpp @@ -25,7 +25,7 @@ #include "mysql.h" int main(int argc, char** argv) { - plan(12);
