Fix multiple test suite failures in Buildbot due to races in the test cases or missing server features not properly checked mysql-test/r/func_misc.result: Move test that requires query cache from main.func_misc to main.query_cache. mysql-test/r/mysqltest.result: Fix test failure due to race. This test case creates > 300 connections in a tight loop, and depending on thread scheduling and load, even though each connection is immediately disconnected before connecting the next one, the server max connections may still be exceeded due to server not being able to free old connections as fast as new ones are made. mysql-test/r/query_cache.result: Move test that requires query cache from main.func_misc to main.query_cache. Move test that requires query cache from main.variables to main.query_cache. mysql-test/r/query_cache_notembedded.result: Move test that requires query cache from main.sp_notembedded to main.query_cache_notembedded. mysql-test/r/sp_notembedded.result: Move test that requires query cache from main.sp_notembedded to main.query_cache_notembedded. mysql-test/r/udf.result: Move test in main.udf that requires query cache to separate file. mysql-test/r/udf_query_cache.result: Move test in main.udf that requires query cache to separate file. mysql-test/r/variables.result: Move test that requires query cache from main.variables to main.query_cache. mysql-test/suite/funcs_1/datadict/processlist_val.inc: Fix race where result file may show state "cleaning up" in the small window between setting COMMAND to 'Sleep' and clearing STATE. mysql-test/suite/rpl/r/rpl_temporary.result: Fix race with suppression of warning message by fixing the test to not generate the warning message in the first place. Problem was a race between creating an anonymous account and resetting the slave. If the slave reset happens before replicating the account, the subsequest deletion of the account will fail to replicate correctly due to missing row. mysql-test/suite/rpl/t/rpl_temporary.test: Fix race with suppression of warning message by fixing the test to not generate the warning message in the first place. Problem was a race between creating an anonymous account and resetting the slave. If the slave reset happens before replicating the account, the subsequest deletion of the account will fail to replicate correctly due to missing row. mysql-test/t/func_misc.test: Move test that requires query cache from main.func_misc to main.query_cache. Move test that requires query cache from main.variables to main.query_cache. mysql-test/t/mysqltest.test: Fix test failure due to race. This test case creates > 300 connections in a tight loop, and depending on thread scheduling and load, even though each connection is immediately disconnected before connecting the next one, the server max connections may still be exceeded due to server not being able to free old connections as fast as new ones are made. mysql-test/t/query_cache.test: Move test that requires query cache to main.query_cache. mysql-test/t/query_cache_notembedded.test: Move test that requires query cache from main.sp_notembedded to main.query_cache_notembedded. mysql-test/t/sp_notembedded.test: Move test that requires query cache from main.sp_notembedded to main.query_cache_notembedded. mysql-test/t/udf.test: Move test in main.udf that requires query cache to separate file. mysql-test/t/udf_query_cache-master.opt: Move test in main.udf that requires query cache to separate file. mysql-test/t/udf_query_cache.test: Move test in main.udf that requires query cache to separate file. mysql-test/t/variables.test: Move test that requires query cache from main.variables to main.query_cache. tests/mysql_client_test.c: In tests that require query cache, skip the test if query cache not available. Do this dynamically rather than using HAVE_QUERY_CACHE, as there is no guarantee that the server we run against was compiled with same preprocessor #define as the mysql_client_test program (and since it is trivial to check dynamically).

Fix for: LP #634955: Assert in _ma_update_at_original_place() Added locking of lock mutex when updating status in external_unlock() for Aria and MyISAM tables. 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.
