Bug#29816 Syntactically wrong query fails with misleading error message The core problem is that an SQL-invoked function name can be a <schema qualified routine name> that contains no <schema name>, but the mysql parser insists that all stored procedures (function, procedures and triggers) must have a <schema name>, which is not true for functions. This problem is especially visible when trying to create a function or when a query contains a syntax error after a function call (in the same query), both will fail with a "No database selected" message if the session is not attached to a particular schema, but the first one should succeed and the second fail with a "syntax error" message. Part of the fix is to revamp the sp name handling so that a schema name may be omitted for functions -- this means that the internal function name representation may not have a dot, which represents that the function doesn't have a schema name. The other part is to place schema checks after the type (function, trigger or procedure) of the routine is known. mysql-test/r/sp-error.result: Add test case result for Bug#29816 mysql-test/r/udf.result: Add test case result for Bug#28318 mysql-test/t/sp-error.test: Add test case for Bug#29816 mysql-test/t/udf.test: Add test case for Bug#28318 sql/sp.cc: Copy the (last) nul byte of the stored routine key and move name parsing code to the sp_name class constructor. sql/sp_head.cc: Revamp routine name parsing for when no schema is specified and omit dot from the qualified name if the routine is not associated with a scheme name. sql/sp_head.h: Name parsing got bigger, uninline by moving to a single unit -- the sp_head.cc file. sql/sql_yacc.yy: Only copy the schema name if one is actually set and check for schema name presence only where it's necessary.

This deadlock occurs when a client issues a HANDLER ... OPEN statement that tries to open a table that has a pending name-lock on it by another client that also needs a name-lock on some other table which is already open and associated to a HANDLER instance owned by the first client. The deadlock happens because the open_table() function will back-off and wait until the name-lock goes away, causing a circular wait if some other name-lock is also pending for one of the open HANDLER tables. Such situation, for example, can be easily repeated by issuing a RENAME TABLE command in such a way that the existing table is already open as a HANDLER table by another client and this client tries to open a HANDLER to the new table name. The solution is to allow handler tables with older versions (marked for flush) to be closed before waiting for the name-lock completion. This is safe because no other name-lock can be issued between the flush and the check for pending name-locks. The test case for this bug is going to be committed into 5.1 because it requires a test feature only avaiable in 5.1 (wait_condition). sql/sql_base.cc: Improve comments in the open_table() function, stating the importance of the handler tables flushing for the back-off process. sql/sql_handler.cc: Allows handler tables flushes when opening new tables in order to avoid potential deadlocks. Add comments explaining the importance of the flush.

This bug is a symptom of the way handler's tables are managed. The most different aspect, compared to the conventional behavior, is that the handler's tables are long lived, meaning that their lifetimes are not bounded by the duration of the command that opened them. For this effect the handler code uses its own list (handler_tables instead of open_tables) to hold open handler tables so that the tables won't be closed at the end of the command/statement. Besides the handler_tables list, there is a hash (handler_tables_hash) which is used to associate handler aliases to tables and to refresh the tables upon demand (flush tables). The current implementation doesn't work properly with refreshed tables -- more precisely when flush commands are issued by other initiators. This happens because when a handler open or read statement is being processed, the associated table has to be opened or locked and, for this matter, the open_tables and handler_tables lists are swapped so that the new table being opened is inserted into the handler_tables list. But when opening or locking the table, if the refresh version is different from the thread refresh version then all used tables in the open_tables list (now handler_tables) are refreshed. In the "refreshing" process the handler tables are flushed (closed) without being properly unlinked from the handler hash. The current implementation also fails to properly discard handlers of dropped tables, but this and other problems are going to be addressed in the fixes for bugs 31397 and 31409. The chosen approach tries to properly save and restore the table state so that no table is flushed during the table open and lock operations. The logic is almost the same as before with the list swapping, but with a working glue code. The test case for this bug is going to be committed into 5.1 because it requires a test feature only avaiable in 5.1 (wait_condition). sql/sql_handler.cc: Backup and reset the open_tables and handler_table lists when opening a new handler table and merge the opened table into the handler_tables list afterwards. When locking, do the same but possibly close the table if a refresh is pending.

This actually, fix for the patch for bug-27354. The problem with the patch was that Item_func_sp::used_tables() was updated, but Item_func_sp::const_item() was not. So, for Item_func_sp, we had the following inconsistency: - used_tables() returned RAND_TABLE, which means that the item can produce "random" results; - but const_item() returned TRUE, which means that the item is a constant one. The fix is to change Item_func_sp::const_item() behaviour: it must return TRUE (an item is a constant one) only if a stored function is deterministic and each of its arguments (if any) is a constant item. mysql-test/r/sp.result: Update result file. mysql-test/t/sp.test: Add test cases for BUG-31035, BUG-31191, BUG-31226 sql/item_func.cc: Make Item::const_item() be consistent with Item::used_tables().

were accidentally removed during a previous rototill of this code. Fixes bug#27692. While it can be argued we should strive to provide a 'secure by default' installation, this happens to be the setup currently documented in the manual as the default, so defer changes that improve security out of the box to a co-ordinated effort later on. For now, make a note about the test databases and anonymous user in mysql_install_db and recommend that mysql_secure_installation be ran for users wishing to remove these defaults. [..re-commit of previously lost change..] scripts/mysql_system_tables_data.sql: Add anonymous accounts. scripts/mysql_install_db.sh: Point users at the mysql_secure_installation script. mysql-test/mysql-test-run.pl: Add a comment where removing anonymous users.

It's not possible to use WaitForSingleObject to wait on a CRITICAL_SECTION, instead use the TryEnterCriticalSection function. - if "mutex" was already taken => return EBUSY - if "mutex" was aquired => return 0 include/config-win.h: Make windows.h define TryEnterCriticalSection mysys/my_winthread.c: Use the TryEnterCriticalSection function to implement pthread_mutex_trylock Prevent recursive behaviour by looking at the RecursionCount variable in the CRITICAL_SECTION struct and return EBUSY from function if the mutex was already locked once.

Adding support for correct handling of pthread_mutex_trylock() on Win32 systems as well as when using the safe mutexes. include/my_pthread.h: Adding win_pthread_mutex_trylock() function as wrapper function for Windows implementation of pthread_mutex_trylock(). Adding flag to safe_mutex_lock() that is shall not abort if the mutex is already locked and instead return EBUSY since this is the POSIX behaviour. mysys/my_winthread.c: Added Win32 wrappper function to handle pthread_mutex_trylock(). mysys/thr_mutex.c: Added parameter 'try_lock' to safe_mutex_lock() to allow it to do double- duty as a pthread_mutex_trylock() in addition to working as pthread_mutex_lock(). The code needs to return EBUSY instead of throwing an error in the event that the mutex is re-locked (we do not have recursive mutexes), but it also requires some special handling to avoid race conditions when calling the real pthread_mutex_{lock,trylock}().
