breaks SBR The problem was that DROP DATABASE ignored any metadata locks on stored functions and procedures held by other connections. This made it possible for DROP DATABASE to drop functions/procedures that were in use by other connections and therefore break statement based replication. (DROP DATABASE could appear in the binlog before a statement using a dropped function/procedure.) This problem was an issue left unresolved by the patch for Bug#30977 where metadata locks for stored functions/procedures were introduced. This patch fixes the problem by making sure DROP DATABASE takes exclusive metadata locks on all stored functions/procedures to be dropped. Test case added to sp-lock.test.

Use __builtin_stpcpy only if the system supports stpcpy. This is necessary as in some cases a call to stpcpy will be emitted if the built-in can not optimized.

Memory was allocated for storing path names inside fn_expand(), which were not free:ed anywhere. This patch fixes the problem by storing the path names in statically allocated buffers instead, which is automatically free:ed when the server exits.

breaks SBR This pre-requisite patch refactors the code for dropping tables, used by DROP TABLE and DROP DATABASE. The patch moves the code for acquiring metadata locks out of mysql_rm_table_part2() and makes it the responsibility of the caller. This in preparation of changing the DROP DATABASE implementation to acquire all metadata locks before any changes are made. mysql_rm_table_part2() is renamed mysql_rm_table_no_locks() to reflect the change.

during EXPLAIN Before the patch, send_eof() of some subclasses of select_result (e.g., select_send::send_eof()) could handle being called after an error had occured while others could not. The methods that were not well-behaved would trigger an ASSERT on debug builds. Release builds were not affected. Consider the following query as an example for how the ASSERT could be triggered: A user without execute privilege on f() does SELECT MAX(key1) INTO @dummy FROM t1 WHERE f() < 1; resulting in "ERROR 42000: execute command denied to user..." The server would end the query by calling send_eof(). The fact that the error had occured would make the ASSERT trigger. select_dumpvar::send_eof() was the offending method in the bug report, but the problem also applied to other subclasses of select_result. This patch uniforms send_eof() of all subclasses of select_result to handle being called after an error has occured.

The test result differs on windows, since it writes out 'localhost:<port>' instead of only 'localhost', since it uses tcp/ip instead of unix sockets on windows. Fixed by replacing that column. Also requires --big-test from some long running tests and added a weekly run of all test requiring --big-test.

breaks SBR This pre-requisite patch removes obsolete and dead code used to remove raid subdirectories and files during DROP DATABASE. Other parts of the raid code have already been removed in WL#5498 and the support for MyISAM raid tables was removed in 5.0.

Problem: with "make package" , many small packages are generated, one per CMake COMPONENT, instead of expected single package. This is due to the new (in cmake 2.8.3) component-based install for archive( e.g ZIP,TGZ ) CPack generators. See http://public.kitware.com/Bug/view.php?id=11452 for discussion. Fix: use CPACK_MONOLITHIC_INSTALL=1 to enforce single package. Reset this variable temporarily to 0 for MSI creation (MSI needs COMPONENTs)

structure buffer). This is a follow-up for WL#4435. The bug actually existed not only MYSQL_TYPE_DATETIME type. The problem was that Item_param::set_value() was written in an assumption that it's working with expressions, i.e. with basic data types. There are two different quick fixes here: a) Change Item_param::make_field() -- remove setting of Send_field::length, Send_field::charsetnr, Send_field::flags and Send_field::type. That would lead to marshalling all data using basic types to the client (MYSQL_TYPE_LONGLONG, MYSQL_TYPE_DOUBLE, MYSQL_TYPE_STRING and MYSQL_TYPE_NEWDECIMAL). In particular, that means, DATETIME would be sent as MYSQL_TYPE_STRING, TINYINT -- as MYSQL_TYPE_LONGLONG, etc. That could be Ok for the client, because the client library does reverse conversion automatically (the client program would see DATETIME as MYSQL_TIME object). However, there is a problem with metadata -- the metadata would be wrong (misleading): it would say that DATETIME is marshaled as MYSQL_TYPE_DATETIME, not as MYSQL_TYPE_STRING. b) Set Item_param::param_type properly to actual underlying field type. That would lead to double conversion inside the server: for example, MYSQL_TIME-object would be converted into STRING-object (in Item_param::set_value()), and then converted back to MYSQL_TIME-object (in Item_param::send()). The data however would be marshalled more properly, and also metadata would be correct. This patch implements b). There is also a possibility to avoid double conversion either by clonning the data field, or by storing a reference to it and using it on Item::send() time. That requires more work and might be done later.

Before this fix, file io for the binary log file was not accounted properly, and showed no io at all. This bug was due to the following issues: 1) file io for the binlog was instrumented: - sometime as "wait/io/file/sql/binlog" - sometime as "wait/io/file/sql/MYSQL_LOG" leading to inconsistent event_names. 2) the binlog file itself was using an IO_CACHE, but the IO_CACHE implementation in mysys/mf_iocache.c was not instrumented to make performance schema calls to record file io. 3) The "wait/io/file/sql/MYSQL_LOG" instrumentation was used for several log files, such as: - the binary log - the slow log - the query log which caused file io in these different log files to be accounted against the same instrument. The instrumentation needs to have a finer grain and report io in different event_names, because each file really serves a different purpose. With this fix: - the IO_CACHE implementation is now instrumented - the "wait/io/file/sql/MYSQL_LOG" instrument has been removed - binlog io is now always instrumented with "wait/io/file/sql/binlog" - the slow log is instrumented with a new name, "wait/io/file/sql/slow_log" - the query log is instrumented with a new name, "wait/io/file/sql/query_log"

bug #57006 "Deadlock between HANDLER and FLUSH TABLES WITH READ LOCK" and bug #54673 "It takes too long to get readlock for 'FLUSH TABLES WITH READ LOCK'". The first bug manifested itself as a deadlock which occurred when a connection, which had some table open through HANDLER statement, tried to update some data through DML statement while another connection tried to execute FLUSH TABLES WITH READ LOCK concurrently. What happened was that FTWRL in the second connection managed to perform first step of GRL acquisition and thus blocked all upcoming DML. After that it started to wait for table open through HANDLER statement to be flushed. When the first connection tried to execute DML it has started to wait for GRL/the second connection creating deadlock. The second bug manifested itself as starvation of FLUSH TABLES WITH READ LOCK statements in cases when there was a constant stream of concurrent DML statements (in two or more connections). This has happened because requests for protection against GRL which were acquired by DML statements were ignoring presence of pending GRL and thus the latter was starved. This patch solves both these problems by re-implementing GRL using metadata locks. Similar to the old implementation acquisition of GRL in new implementation is two-step. During the first step we block all concurrent DML and DDL statements by acquiring global S metadata lock (each DML and DDL statement acquires global IX lock for its duration). During the second step we block commits by acquiring global S lock in COMMIT namespace (commit code acquires global IX lock in this namespace). Note that unlike in old implementation acquisition of protection against GRL in DML and DDL is semi-automatic. We assume that any statement which should be blocked by GRL will either open and acquires write-lock on tables or acquires metadata locks on objects it is going to modify. For any such statement global IX metadata lock is automatically acquired for its duration. The first problem is solved because waits for GRL become visible to deadlock detector in metadata locking subsystem and thus deadlocks like one in the first bug become impossible. The second problem is solved because global S locks which are used for GRL implementation are given preference over IX locks which are acquired by concurrent DML (and we can switch to fair scheduling in future if needed). Important change: FTWRL/GRL no longer blocks DML and DDL on temporary tables. Before this patch behavior was not consistent in this respect: in some cases DML/DDL statements on temporary tables were blocked while in others they were not. Since the main use cases for FTWRL are various forms of backups and temporary tables are not preserved during backups we have opted for consistently allowing DML/DDL on temporary tables during FTWRL/GRL. Important change: This patch changes thread state names which are used when DML/DDL of FTWRL is waiting for global read lock. It is now either "Waiting for global read lock" or "Waiting for commit lock" depending on the stage on which FTWRL is. Incompatible change: To solve deadlock in events code which was exposed by this patch we have to replace LOCK_event_metadata mutex with metadata locks on events. As result we have to prohibit DDL on events under LOCK TABLES. This patch also adds extensive test coverage for interaction of DML/DDL and FTWRL. Performance of new and old global read lock implementations in sysbench tests were compared. There were no significant difference between new and old implementations.

This fix is a follow up on the fix for similar issue 56761. When sanitizing data read from the events_waits_history_long table, the code needs also to sanitize the schema_name / object_name / file_name pointers, because such pointers could also hold invalid values. Checking the string length alone was required but not sufficient. This fix verifies that: - the table schema and table name used in table io events - the file name used in file io events are valid pointers before dereferencing these pointers.
