From 4dcbefcc07940d2a86811a778672e053a41cc487 Mon Sep 17 00:00:00 2001 From: unknown Date: Mon, 23 Aug 2004 16:15:57 +0200 Subject: Fix for BUG#5033 "When using temporary tables truncate does NOT reset the auto_increment counter" (ok'd by CTO to fix it in 4.0). Fix to make mysql-test-run work with all Valgrind versions. mysql-test/mysql-test-run.sh: fixing mysql-test-run.sh so that it works indifferently with Valgrind 1.x, 2.x (versions <= 2.0.0 refuse --tool option; versions >=2.1.2 require it; 2.1.0 accepts it). I hope the shell code is portable enough; anyway Valgrind only runs on Linux... I tested it with 2.0.0, 2.1.0, 2.1.2. mysql-test/r/truncate.result: result update mysql-test/t/truncate.test: testing if TRUNCATE resets autoinc counter for temp tables (BUG#5033); testing difference with DELETE FROM. sql/sql_delete.cc: in mysql_truncate(), always reset the autoinc counter, as manual says (even if it's a temp table, which was BUG#5033). --- sql/sql_delete.cc | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) (limited to 'sql/sql_delete.cc') diff --git a/sql/sql_delete.cc b/sql/sql_delete.cc index b568166a766..555e63b9e32 100644 --- a/sql/sql_delete.cc +++ b/sql/sql_delete.cc @@ -545,15 +545,13 @@ int mysql_truncate(THD *thd, TABLE_LIST *table_list, bool dont_send_ok) int error; DBUG_ENTER("mysql_truncate"); + bzero((char*) &create_info,sizeof(create_info)); /* If it is a temporary table, close and regenerate it */ if (!dont_send_ok && (table_ptr=find_temporary_table(thd,table_list->db, table_list->real_name))) { TABLE *table= *table_ptr; - HA_CREATE_INFO create_info; table->file->info(HA_STATUS_AUTO | HA_STATUS_NO_LOCK); - bzero((char*) &create_info,sizeof(create_info)); - create_info.auto_increment_value= table->file->auto_increment_value; db_type table_type=table->db_type; strmov(path,table->path); @@ -596,7 +594,6 @@ int mysql_truncate(THD *thd, TABLE_LIST *table_list, bool dont_send_ok) DBUG_RETURN(-1); } - bzero((char*) &create_info,sizeof(create_info)); *fn_ext(path)=0; // Remove the .frm extension error= ha_create_table(path,&create_info,1) ? -1 : 0; query_cache_invalidate3(thd, table_list, 0); -- cgit v1.2.1
