| * Fixed LP bug #668644.Igor Babaev2010-11-082-2/+72
| | | | | | | | | | | | | | | | | | | | The pushdown condition for the sorted table in a query can be complemented by the conditions from HAVING. This transformation is done in JOIN::exec pretty late after the original pushdown condition have been saved in the field pre_idx_push_select_cond for the sorted table. So this field must be updated after the inclusion of the condition from HAVING.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement os_event_wait_time() for POSIX systems. In the purge thread, use os_event_wait_time() when sleeping rather than sleep, and signal the event when server shuts down, so we do not need to wait for upto 10 seconds until the purge thread wakes up. Also fix bug that warnings that were pushed after we call set_ok_status() were not included in the waning count sent to the client in the result packet. Also in mysqltest, in recursive die() invocation at least print the message before aborting. client/mysqltest.cc: If we detect recursive die(), at least print the message before aborting. mysql-test/r/warnings_debug.result: Test case. mysql-test/t/warnings_debug.test: Test case. sql/handler.cc: Force generation of a warning with specific debug option, for testing. sql/protocol.cc: Fix wrong DBUG_ENTER sql/sql_class.h: Add method to count warnings pushed after set_ok_status() is called. sql/sql_error.cc: Also count warnings pushed after set_ok_status() is called. storage/xtradb/include/os0sync.h: Implement working os_sync_wait_time() for POSIX. storage/xtradb/include/srv0srv.h: Make the purge thread wait for an event when sleeping, so we can signal it to wakeup immediately at shutdown. storage/xtradb/log/log0log.c: Make the purge thread wait for an event when sleeping, so we can signal it to wakeup immediately at shutdown. storage/xtradb/os/os0sync.c: Implement working os_sync_wait_time() for POSIX. storage/xtradb/srv/srv0srv.c: Make the purge thread wait for an event when sleeping, so we can signal it to wakeup immediately at shutdown.

Fixed that 'source' command doesn't cause mysql command line tool to exit on error. DEBUG_EXECUTE() and DEBUG_EVALUATE_IF() should not execute things based on wildcards. (Allows one to run --debug with mysql-test-run scripts that uses @debug) Fixed several core dump, deadlock and crashed table bugs in handling of LOCK TABLE with MERGE tables: - Added priority of locks to avoid crashes with MERGE tables. - Added thr_lock_merge() to allow one to merge two results of thr_lock(). Fixed 'not found row' bug in REPLACE with Aria tables. Mark MyISAM tables that are part of MERGE with HA_OPEN_MERGE_TABLE and set the locks to have priority THR_LOCK_MERGE_PRIV. - By sorting MERGE tables last in thr_multi_unlock() it's safer to release and relock them many times (can happen when TRIGGERS are created) Avoid printing (null) in debug file (to easier find out wrong NULL pointer usage with %s). client/mysql.cc: Fixed that 'source' command doesn't cause mysql command line tool to exit on error. client/mysqltest.cc: Don't send NULL to fn_format(). (Can cause crash on Solaris when using --debug) dbug/dbug.c: DEBUG_EXECUTE() and DEBUG_EVALUATE_IF() should not execute things based on wildcards. include/my_base.h: Added flag to signal if one opens a MERGE table. Added extra() command to signal that one is not part of a MERGE table anymore. include/thr_lock.h: Added priority for locks (needed to fix bug in thr_lock when using MERGE tables) Added option to thr_unlock() if get_status() should be called. Added prototype for thr_merge_locks(). mysql-test/mysql-test-run.pl: Ignore crashed table warnings for tables named 'crashed'. mysql-test/r/merge.result: Renamed triggers to make debugging easier. Added some CHECK TABLES to catch errors earlier. Additional tests. mysql-test/r/merge_debug.result: Test of error handling when reopening MERGE tables. mysql-test/r/udf_query_cache.result: Added missing flush status mysql-test/suite/parts/r/partition_repair_myisam.result: Update results mysql-test/t/merge.test: Renamed triggers to make debugging easier. Added some CHECK TABLES to catch errors earlier. Additional tests. mysql-test/t/merge_debug.test: Test of error handling when reopening MERGE tables. mysql-test/t/udf_query_cache.test: Added missing flush status mysys/my_getopt.c: Removed not used variable mysys/my_symlink2.c: Changed (null) to (NULL) to make it easier to find NULL arguments to DBUG_PRINT() functions. (On linux, NULL to sprintf is printed 'null') mysys/thr_lock.c: Added priority of locks to avoid crashes with MERGE tables. Added thr_lock_merge() to allow one to merge two results of thr_lock(). - This is needed for MyISAM as all locked table must share the same status. If not, you will not see newly inserted rows in other instances of the table. If calling thr_unlock() with THR_UNLOCK_UPDATE_STATUS, call update_status() and restore_status() for the locks. This is needed in some rare cases where we call thr_unlock() followed by thr_lock() without calling external_unlock/external_lock in between. Simplify loop in thr_multi_lock(). Added 'start_trans', which is called at end of thr_multi_lock() when all locks are taken. - This was needed by Aria to ensure that transaction is started when we got all locks, not at get_status(). Without this, some rows could not be visible when we lock two tables at the same time, causing REPLACE using two tables to fail unexpectedly. sql/handler.cc: Add an assert() in handler::print_error() for "impossible errors" (like table is crashed) when --debug-assert-if-crashed-table is used. sql/lock.cc: Simplify mysql_lock_tables() code if get_lock_data() returns 0 locks. Added new parameter to thr_multi_unlock() In mysql_unlock_read_tables(), call first externa_unlock(), then thr_multi_unlock(); This is same order as we do in mysql_unlock_tables(). Don't abort locks in mysql_lock_abort() for merged tables when a MERGE table is deleted; Would cause a spin lock. Added call to thr_merge_locks() in mysql_lock_merge() to ensure consistency in thr_locks(). - New locks of same type and table is stored after the old lock to ensure that we get the status from the original lock. sql/mysql_priv.h: Added debug_assert_if_crashed_table sql/mysqld.cc: Added --debug-assert-if-crashed-table sql/parse_file.cc: Don't print '(null)' in DBUG_PRINT of no dir given sql/set_var.cc: Increase default size of buffer for @debug variable. sql/sql_base.cc: In case of error from reopen_table() in reopen_tables(), call unlock_open_table() and restart loop. - This fixed bug when we twice deleted same table from open_cache. Don't take name lock for already name locked table in open_unireg_entry(). - Fixed bug when doing repair in reopen_table(). - In detach_merge_children(), always detach if 'clear_refs' is given. We can't trust parent->children_attached as this function can be called twice, first time with clear_refs set to 0. sql/sql_class.cc: Changed printing of (null) to "" in set_thd_proc_info() sql/sql_parse.cc: Added DBUG sql/sql_trigger.cc: Don't call unlink_open_table() if reopen_table() fails as the table may already be freed. storage/maria/ma_bitmap.c: Fixed DBUG_ASSERT() in allocate_tail() storage/maria/ma_blockrec.c: Fixed wrong calculation of row length for very small rows in undo_row_update(). - Fixes ASSERT() when doing undo. storage/maria/ma_blockrec.h: Added _ma_block_start_trans() and _ma_block_start_trans_no_versioning() storage/maria/ma_locking.c: Call _ma_update_status_with_lock() when releasing write locks. - Fixes potential problem with updating status without the proper lock. storage/maria/ma_open.c: Changed to use start_trans() instead of get_status() to ensure that we see all rows in all locked tables when we got the locks. - Fixed 'not found row' bug in REPLACE with Aria tables. storage/maria/ma_state.c: Added _ma_update_status_with_lock() and _ma_block_start_trans(). This is to ensure that we see all rows in all locked tables when we got the locks. storage/maria/ma_state.h: Added _ma_update_status_with_lock() storage/maria/ma_write.c: More DBUG_PRINT storage/myisam/mi_check.c: Fixed error message storage/myisam/mi_extra.c: Added HA_EXTRA_DETACH_CHILD: - Detach MyISAM table to not be part of MERGE table (remove flag & lock priority). storage/myisam/mi_locking.c: Call mi_update_status_with_lock() when releasing write locks. - Fixes potential problem with updating status without the proper lock. Change to use new HA_OPEN_MERGE_TABLE flag to test if MERGE table. Added mi_fix_status(), called by thr_merge(). storage/myisam/mi_open.c: Added marker if part of MERGE table. Call mi_fix_status() in thr_lock() for transactional tables. storage/myisam/myisamdef.h: Change my_once_flag to uint, as it stored different values than just 0/1 Added 'open_flag' to store state given to mi_open() storage/myisammrg/ha_myisammrg.cc: Add THR_LOCK_MERGE_PRIV to THR_LOCK_DATA to get MERGE locks sorted after other types of locks. storage/myisammrg/myrg_locking.c: Remove windows specific code. storage/myisammrg/myrg_open.c: Use HA_OPEN_MERGE_TABLE to mi_open(). Set HA_OPEN_MERGE_TABLE for linked MyISAM tables. storage/xtradb/buf/buf0buf.c: Fixed compiler warning storage/xtradb/buf/buf0lru.c: Initialize variable that could be used not initialized.

The problem was a combination of the following factors: - Item_sum_hybrid::fix_fields() might use the argument (args[0]) to calculate 'hybrid_field_type' which was later used to decide how the data should be sent to the client. - Item_sum::make_field() might use the argument again to calculate the field's type when sending result set metadata to the client. - The argument could be changed in between these two calls via Item::set_arg() leading to inconsistent metadata being reported. Here is what was happening for the bug's test case: 1. Item_sum_hybrid::fix_fields() calculates hybrid_field_type as MYSQL_TYPE_LONGLONG based on args[0] which is an Item::SUBSELECT_ITEM at that time. 2. A temporary table is created to execute the query. create_tmp_field_from_item() creates a Field_long object according to the subselect's max_length. 3. The subselect item in Item_sum_hybrid is replaced by the Item_field object referencing the newly created Field_long. 4. Item_sum::make_field() rightfully returns the MYSQL_TYPE_LONG type when calculating the result set metadata. 5. When sending the actual data, Item::send() relies on the virtual field_type() function which in our case returns previously calculated hybrid_field_type == MYSQL_TYPE_LONGLONG. It looks like the only solution is to never refer to the argument's metadata after the result metadata has been calculated in fix_fields(), since the argument itself may be different by then. In this sense, Item_sum::make_field() should never be used, because it may rely on the argument's metadata and is only called after fix_fields(). The "default" implementation in Item::make_field() should be used instead as it relies only on field_type(), but not on the argument's type. Fixed by removing Item_sum::make_field() so that the superclass implementation Item::make_field() is always used. mysql-test/r/func_group.result: Added a test case for bug #54465. mysql-test/t/func_group.test: Added a test case for bug #54465. sql/item_sum.cc: Removed Item_sum::make_field() so that the superclass implementation Item::make_field() is always used. sql/item_sum.h: Removed Item_sum::make_field() so that the superclass implementation Item::make_field() is always used.

For "c NOT BETWEEN f1 AND f2" predicates, get_mm_tree() produces a disjunction of the SEL_ARG trees for "f1 > c" and "f2 < c". If one of the trees is empty (i.e. one of the arguments is not sargable) the resulting tree should be empty as well, since the whole expression in this case is not sargable. The above logic is implemented in get_mm_tree() as follows. The initial state of the resulting tree is NULL (aka empty). We then iterate through arguments and compute the corresponding SEL_ARG tree (either "f1 > c" or "f2 < c"). If the resulting tree is NULL, it is simply replaced by the generated tree. Otherwise it is replaced by a disjunction of itself and the generated tree. The obvious flaw in this implementation is that if the first argument is not sargable and thus produces a NULL tree, the resulting tree will simply be replaced by the tree for the second argument. As a result, "c NOT BETWEEN f1 AND f2" will end up as just "f2 < c". Fixed by adding a check so that when the first argument produces an empty tree for the NOT BETWEEN case, the loop is aborted with an empty tree as a result. The whole idea of using a loop for 2 arguments does not make much sense, but it was probably used to avoid code duplication for several BETWEEN variants.

When flattening nested joins, simplify_joins() tracks if the name resolution list needs to be updated by setting fix_name_res to TRUE if the current loop iteration has done any transformations to the join table list. The problem was that the flag was not reset before the next loop iteration leading to unnecessary "fixing" of the name resolution list which in turn could lead to a loop (i.e. circularly-linked part) in that list. This was causing problems on subsequent execution when used together with stored procedures or prepared statements. Fixed by making sure fix_name_res is reset on every loop iteration. mysql-test/r/join.result: Added a test case for bug #53544. mysql-test/t/join.test: Added a test case for bug #53544. sql/sql_select.cc: Make sure fix_name_res is reset on every loop iteration.

During rare circumstances a String object could crash when it was requested to allocate new memory. A crash could occcur in Field_double::val_str() because of a pointer referencing memory inside a String object which was of unknown size. And finally, the geometric collection should not accept arguments which are non geometric. mysql-test/r/gis.result: * Test cases change because we intercept the error behind the previous crashes much earlier. sql/field.cc: * It makes no sense to impose a lower limit on the length and not setting a upper limit will cause crashes later. sql/item_geofunc.h: * Disallow for binding with field- and item types which differ from MYSQL_TYPE_GEOMETRY types.

When destroying the temporary table used to execute a query for a derived table, JOIN::destroy() did not clean up Item_fields pointing to fields in the temporary table. This led to dereferencing a dangling pointer when printing out the items tree later in the outer SELECT. The solution is an addendum to the patch for bug37362: in addition to cleaning up items in tmp_all_fields3, do the same for items in tmp_all_fields1, since now we have an example where this is necessary. mysql-test/r/join.result: Added test cases for bug#55568 and a duplicate bug #54468. mysql-test/t/join.test: Added test cases for bug#55568 and a duplicate bug #54468. sql/field.cc: Make sure field->table_name is not set to NULL in Field::make_field() to avoid assertion failure in Item_field::make_field() after cleaning up items (the assertion fired in udf.test when running the test suite with the patch applied). sql/sql_select.cc: In addition to cleaning up items in tmp_all_fields3, do the same for items in tmp_all_fields1. Introduce a new helper function to avoid code duplication. sql/sql_select.h: Introduce a new helper function to avoid code duplication in JOIN::destroy().
