with two connections doing LOCK TABLE+INSERT DELAYED". Disabled --ps-protocol for this part of the test as INSERT DELAYED simply doesn't work with it under LOCK TABLES.

LOCK TABLE+INSERT DELAYED The problem was that the server could crash if the insert delayed handler thread was killed due to a conflicting shared metadata lock. This could happen because the metadata lock ticket was added to the handler thread before it was properly initialized. This patch moves the cloning of the acquired metadata lock ticket until after the handler thread has been properly initialized.

The Item_cache_datetime::val_str function wasn't taking into account that time could be negative. This led to failed assertion. Now Item_cache_datetime::val_str correctly converts negative time values from integer to string representation.

The problem was that deadlocks involving INSERT DELAYED were not detected. The reason for this is that two threads are involved in INSERT DELAYED: the connection thread and the handler thread. The connection thread would wait while the handler thread acquired locks and opened the table. In essence, this adds an edge to the wait-for-graph between the connection thread and the handler thread that the deadlock detector is unaware of. Therefore many deadlocks involving INSERT DELAYED were not detected. This patch fixes the problem by having the connection thread acquire the metadata lock the table before starting the handler thread. This allows the deadlock detector to detect any possible deadlocks resulting from trying to acquire a metadata lock the table. If a metadata lock is successfully acquired, the handler thread is started and given a copy of the ticket representing the metadata lock. When the handler thread then tries to lock and open the table, it will find that it already has the metadata lock and therefore not acquire any new metadata locks. Test cases added to delayed.test.

Problem: ENUM columns are sorted and distributed according to their numeric value, but Field::hash() incorrectly passed string character set (utf32) in combination with numeric value to the hash function, which made assertion fail. Fix: pass "binary" character set in combination with numeric value to the hash function. mysql-test/suite/parts/r/part_ctype_utf32.result Adding tests mysql-test/suite/parts/t/part_ctype_utf32.test Adding test sql/field.cc Pass correct character set pointer to the hash function.

The include/mysqlhotcopy.inc had an error in the 'if' condition, so it failed if the mysqlhotcopy tool was found. per-file comments: mysql-test/include/mysqlhotcopy.inc test should proceed exactly if the mysqlhotcopy was set. mysql-test/mysql-test-run.pl don't set the MYSQL_HOTCOPY variable if no mysqlhotcopy was found.

my_thread_global_end() now sets mysql_thread_basic_global_init_done= 0 to ensure destroyed mutexes are not reused. I verified that clearing this flag will not result in the redundant allocation of other resources allocated by my_thread_global_init() and my_thread_basic_global_init().

The ALTER PARTITION and SELECT seemed to be deadlocked when having innodb_thread_concurrency = 1. Problem was that there was unreleased latches in the ALTER PARTITION thread which was needed by the SELECT thread to be able to continue. Solution was to release the latches by commit before requesting upgrade to exclusive MDL lock. Updated according to reviewers comments (3).

attempt to install a plugin twice Server crashes when [UN]INSTALL PLUGIN fails (returns an error) and general log is disabled and there are audit plugins interested in MYSQL_AUDIT_GENERAL_CLASS. When audit event is triggered, audit subsystem acquires interested plugins by walking through plugin list. Evidently plugin list iterator protects plugin list by acquiring LOCK_plugin, see plugin_foreach_with_mask(). On the other hand [UN]INSTALL PLUGIN is acquiring LOCK_plugin rather for a long time. When audit event is triggered during [UN]INSTALL PLUGIN, plugin list iterator acquires the same lock (within the same thread) second time. Repeatable only with general_log disabled, because general_log triggers MYSQL_AUDIT_GENERAL_LOG event, which acquires audit plugins before [UN]INSTALL PLUGIN acquired LOCK_plugin. With this fix we pre-acquire audit plugins for events that may potentially occur during [UN]INSTALL PLUGIN. This hack should be removed when LOCK_plugin is fixed so it protects only what it supposed to protect. No test case for this fix - we do not have facility to test audit plugins yet.

Problems: - dot character was always printed as decimal point instead of localized decimal point for short numbers without thousands - Item_func_format::val_str always returned values in ASCII format, regargless of @@character_set_connection, which in case of utf32 led to crash in debug build, or to incorrect values in release build. Fix: - Adding a piece of code to replace dot character to localized decimal point in short numbers. - Changing parent class for Item_func_format to Item_str_ascii_func, because its val_str() implementation is heavily ASCII oriented.

on CREATE TABLE .. SELECT I_S.PART This assert was triggered if an InnoDB table was created using CREATE TABLE ... AS SELECT where the query used an I_S table, and a view existed in the database. It would also be triggered for any statement changing an InnoDB table (e.g. INSERT, UPDATE, DELETE) which had a subquery referencing an I_S table. The assert was triggered if open_normal_and_derived_tables() failed and a statement transaction had been started. This will usually not happen as tables are opened before a statement transaction is started. However, e.g. CREATE TABLE ... AS SELECT starts a transaction in order to insert tuples into the new table. And if the subquery references an I_S table, all current tables and views can be opened in order to fill the I_S table on the fly. If a view is discovered, open will fail as it is instructed to open tables only (OPEN_TABLE_ONLY). This would cause the assert to be triggered. The assert was added in the patch for Bug#52044 and was therefore not in any released versions of the server. This patch fixes the problem by adjusting the assert to take into consideration the possibility of tables being opened as part of an I_S query. This is similar to what is already done for close_tables_for_reopen(). Test case added to information_schema_inno.test.

temp table This patch introduces two key changes in the replication's behavior. Firstly, it reverts part of BUG#51894 which puts any update to temporary tables into the trx-cache. Now, updates to temporary tables are handled according to the type of their engines as a regular table. Secondly, an unsafe mixed statement, (i.e. a statement that access transactional table as well non-transactional or temporary table, and writes to any of them), are written into the trx-cache in order to minimize errors in the execution when the statement logging format is in use. Such changes has a direct impact on which statements are classified as unsafe statements and thus part of BUG#53259 is reverted.

Problem: a few functions did not calculate their max_length correctly. This is an after-fix for WL#2649 Number-to-string conversions". Fix: changing the buggy functions to calculate max_length using fix_char_length() introduced in WL#2649, instead of setting max_length directly mysql-test/include/ctype_numconv.inc Adding new tests mysql-test/r/ctype_binary.result Adding new tests mysql-test/r/ctype_cp1251.result Adding new tests mysql-test/r/ctype_latin1.result Adding new tests mysql-test/r/ctype_ucs.result Adding new tests mysql-test/r/ctype_utf8.result Adding new tests mysql-test/t/ctype_utf8.test Including ctype_numconv sql/item.h - Introducing new method fix_char_length_ulonglong(), for the cases when length is potentially greater than UINT_MAX32. This method removes a few instances of duplicate code, e.g. in item_strfunc.cc. - Setting collation in Item_copy properly. This change fixes wrong metadata on client side in some cases, when "binary" instead of the real character set was reported. sql/item_cmpfunc.cc - Using fix_char_length() and max_char_length() methods, instead of direct access to max_length, to calculate item length properly. - Moving count_only_length() in COALESCE after agg_arg_charsets_for_string_result(). The old order was incorrect and led to wrong length calucation in case of multi-byte character sets. sql/item_func.cc Fixing that count_only_length() didn't work properly for multi-byte character sets. Using fix_char_length() and max_char_length() instead of direct access to max_length. sql/item_strfunc.cc - Using fix_char_length(), fix_char_length_ulonglong(), max_char_length() instead of direct access to max_length. - Removing wierd condition: "if (collation.collation->mbmaxlen > 0)", which is never FALSE.

check_if_table_exists() This assert was triggered when the server tried to load plugins while running in embedded server mode. In embedded server mode, check_if_table_exists() was used to check if mysql.plugin existed so that ER_NO_SUCH_TABLE could be silently ignored. The problem was that this check was done without acquiring a metadata lock on mysql.plugin first. This triggered the assert. This patch fixes the problem by removing the call to check_if_table_exists() from plugin_load(). Instead an error handler which traps ER_NO_SUCH_TABLE is installed before trying to open mysql.plugin when running in embedded server mode. No test coverage added since this assert was triggered by existing tests running in embedded server mode.

'CREATE TABLE IF NOT EXISTS ... SELECT' behaviour BUG#47132, BUG#47442, BUG49494, BUG#23992 and BUG#48814 will disappear automatically after the this patch. BUG#55617 is fixed by this patch too. This is the 5.5 part. It implements: - 'CREATE TABLE IF NOT EXISTS ... SELECT' statement will not insert anything and binlog anything if the table already exists. It only generate a warning that table already exists. - A couple of test cases for the behavior changing.
