| | | | | | | | - Avoid some realloc() during startup - Ensure that file_key_management_plugin frees it's memory early, even if it's linked statically. - Fixed compiler warnings from unused variables and missing destructors - Fixed wrong indentation

* Stage 2 of MDEV-6152:Monty2015-08-211-17/+1
| | | | | | | | - Added mem_root to all calls to new Item - Added private method operator new(size_t size) to Item to ensure that we always use a mem_root when creating an item. This saves use once call to current_thd per Item creation
* MDEV-8010 - Avoid sql_alloc() in Items (Patch #1)Sergey Vojtovich2015-08-211-2/+3
| | | | | | | Added mandatory thd parameter to Item (and all derivative classes) constructor. Added thd parameter to all routines that may create items. Also removed "current_thd" from Item::Item. This reduced number of pthread_getspecific() calls from 290 to 177 per OLTP RO transaction.
* SET STATEMENT timestamp=xxx ....Sergei Golubchik2015-04-091-3/+9
| | | | | | | | | | | fix sys_var->is_default() method (that was using default_val property in a global sys_var object to track per-session state): * move timestamp to a dedicated Sys_var_timestamp class (in fact, rename Sys_var_session_special_double to Sys_var_timestamp) * make session_is_default a virtual method with a special implementation for timestamps * other variables don't have a special behavior for default values and can have session_is_default() to be always false.
* MDEV-6960 Server crashes in check_alter_user on setting a default role via PSSergei Golubchik2015-02-281-1/+1
| | | | | | | | | | | | | | There were two issues: * set_var_default_role::user was overwritten with a new value, allocated in the thd->mem_root, which is reset between executions. That was causing the crash. Solved by introducing set_var_default_role::real_user * when privilege tables were opened on EXECUTE, the reprepare_observer would abort the statement (as privilege tables are opened using the local TABLE_LIST that doesn't preserve metadata from PREPARE, so reprepare_observer thought they're changed). This issue also applied to SET PASSWORD. Solved by disabling reprepare_observer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When a system variable is being set to the DEFAULT value, the server segfaults if there is no 'default' defined for that system variable. For example, for the following statements server segfaults. set session rand_seed1=DEFAULT; set session rand_seed2=DEFAULT; Analysis: The class sys_var represents one system variable. The class set_var represents one system variable that is to be updated. The class set_var contains two pieces of information, the system variable to object (set_var::var) member and the value to be updated (set_var::value). When the given value is 'default', the set_var::value will be NULL. To update a system variable the member set_var::update() will be called, which in turn will call sys_var::update() or sys_var::set_default() depending on whether a value has been provided or not. If the sys_var::set_default() is called, then the default value is obtained either from the session scope or the global scope. This default value is stored in a local temporary set_var object and then passed on to the sys_var::update() call. A local temporary set_var object is needed because sys_var::set_default() does not take set_var as an argument. In the given scenario, the set_var::update() called sys_var::set_default(). And this sys_var::set_default() obtains the default value and then calls sys_var::update(). To pass this value to sys_var::update() a local set_var object is being created. While creating this local set_var object, its member set_var::var was incorrectly left as 0. Solution: Instead of creating a local set_var object, the sys_var::set_default() can take the set_var object as an argument just like sys_var::update(). rb://1996 approved by Nirbhay and Ramil.

| | | * Bug #14211565 CRASH WHEN ATTEMPTING TO SET SYSTEM VARIABLE TO RESULT OF VALUES()Annamalai Gurusami2013-02-221-5/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When the VALUES() function is inappropriately used in the SET stmt the server exits. set port = values(v); This happens because the values(v) will be parsed as an Item_insert_value by the parser. Both Item_field and Item_insert_value return the type as FIELD_ITEM. But for Item_insert_value the field_name member is NULL. In set_var constructor, when the type of the item is FIELD_ITEM we try to access the non-existent field_name. The class hierarchy is as follows: Item -> Item_ident -> Item_field -> Item_insert_value The Item_ident::field_name is NULL for Item_insert_value. Solution: In the parsing stage, in the set_var constructor if the item type is FIELD_ITEM and if the field_name is non-existent, then it is probably the Item_insert_value. So leave it as it is for later evaluation. rb://2004 approved by Roy and Norvald.
