Lixun Peng	82eedf4e97	Makeing rpl_filter for each Master_info. Users can set different repplication filter rules for each replication connection, in my.cnf or command line. But the rules set online will not record in master.info, it means if users restart MySQL, these rules will lose. So if users wantn't their replication filter rules lose, they should write the rules in my.cnf. Users can set rules by 2 ways: 1. Online SET command, "SET connection_name.replication_filter_settings = rules;". 2. In my.cnf, "connection_name.replication_filter_settings = rules". If no connection_name in my.cnf, this rule will apply for ALL replication connection. If no connetion_name in SET statement, this rull will apply for default_connection_name.	13 years ago
Alexey Botchkov	1a600125ff	MDEV-3917 multiple use locks (GET_LOCK) in one connection. The patch contributed by Konstantin Osipov applied. Native comments: Implement multiple user-level locks per connection. GET_LOCK() function in MySQL allows a connection to hold at most one user level lock. Taking a new lock automatically releases the old lock, if any. The limit of one lock per session existed since early versions of MySQL didn't have a deadlock detector for SQL locks. MDL patches in MySQL 5.5 added a deadlock detector, so starting from 5.5 it became possible to take multiple locks in any order -- a deadlock, should it occur, would be detected and an error returned to the client which closed the wait chain. This is exactly what is done in this patch: ULLs are moved to use MDL subsystem.	13 years ago

Vladislav Vaintroub	5ae72bb73c	MDEV-4356 : MariaDB does not start if bind-address gets resolved to more than single IP address. MySQL bug http://bugs.mysql.com/bug.php?id=61713 was fixed in 5.5 Fix is to remove check for multiple entries returned by getaddrinfo(), and use the first entry that works - i.e socket can be created. Unlike Oracle/MySQL's fix ,this one is kept minimal : - we do not prioritize IPv4 over IPv6, orr other way around, and just rely on operating system to sort getaddrinfo() entries in sensible order. There is RFC that defines what is sensible order for getaddrinfo entries ( RFC 3484), and OS specific tweaks are also possible , like /etc/gai.conf o Linux. - also, we do not force "0.0.0.0" address if bind-address is not given - this would be a change in behavior of 5.5 at least on Windows, where passing NULL as to getaddrinfo() gives back IPv6-wildcard.	13 years ago

Michael Widenius	8ed283d882	Fixed bug MPDEV-628 / LP:989055 - Querying myisam table metadata may corrupt the table. The issue was that there was that SHOW commands could open the table in the store engine, even in cases where it should not be allowed to do that (ie, the storage engines meta data for that table was under big changes). The cases where this should not be allowed are: - ALTER TABLE DISABLE KEYS - ALTER TABLE ENABLE KEYS - REPAIR TABLE - OPTIMIZE TABLE - DROP TABLE This patch adds a new mode, protected_against_usage(). If this is used then the SHOW command will wait until the table is accessable. This is implemented by re-using the already exising 'version' flag for TABLE_SHARE. It also added functions to be used to change TABLE_SHARE->version instead of changing it directly. mysql-test/r/myisam-metadata.result: Added test case mysql-test/t/myisam-metadata.test: Added test case sql/mysqld.cc: Start from refresh_version 2 as 0 and 1 are reserved. sql/sql_admin.cc: Added MYSQL_OPEN_FOR_REPAIR Updated call to wait_while_table_is_used() sql/sql_base.cc: Updated call to wait_while_table_is_used() - Allow one to specify how the table should be removed (for all commands except show or for all commands). - Don't allow one to reopen the table if one has called share->protect_against_usage() sql/sql_base.h: Added TDC_RT_REMOVE_NOT_OWN_AND_MARK_NOT_USABLE, which is used to mark that no one can reopen this table, except with MYSQL_OPEN_FOR_REPAIR . - Added MYSQL_OPEN_FOR_REPAIR - Updated prototype for wait_while_table_is_used() sql/sql_table.cc: Updated call to wait_while_table_is_used() Use MYSQL_OPEN_FOR_REPAIR for open tables that where repaired. sql/sql_truncate.cc: Updated call to wait_while_table_is_used() sql/table.cc: Use set_refresh_version() sql/table.h: Added functions to be used to change TABLE_SHARE->version instead of changing it directly	13 years ago

Michael Widenius	a260b15554	MDEV-4011 Added per thread memory counting and usage Base code and idea from a patch from by plinux at Taobao. The idea is that we mark all memory that are thread specific with MY_THREAD_SPECIFIC. Memory counting is done per thread in the my_malloc_size_cb_func callback function from my_malloc(). There are plenty of new asserts to ensure that for a debug server the counting is correct. Information_schema.processlist gets two new columns: MEMORY_USED and EXAMINED_ROWS. - The later is there mainly to show how query is progressing. The following changes in interfaces was needed to get this to work: - init_alloc_root() amd init_sql_alloc() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - One now have to use alloc_root_set_min_malloc() to set min memory to be allocated by alloc_root() - my_init_dynamic_array() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - my_net_init() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - Added flag for hash_init() so that one can mark hash table to be thread specific. - Added flags to init_tree() so that one can mark tree to be thread specific. - Removed with_delete option to init_tree(). Now one should instead use MY_TREE_WITH_DELETE_FLAG. - Added flag to Warning_info::Warning_info() if the structure should be fully initialized. - String elements can now be marked as thread specific. - Internal HEAP tables are now marking it's memory as MY_THREAD_SPECIFIC. - Changed type of myf from int to ulong, as this is always a set of bit flags. Other things: - Removed calls to net_end() and thd->cleanup() as these are now done in ~THD() - We now also show EXAMINED_ROWS in SHOW PROCESSLIST - Added new variable 'memory_used' - Fixed bug where kill_threads_for_user() was using the wrong mem_root to allocate memory. - Removed calls to the obsoleted function init_dynamic_array() - Use set_current_thd() instead of my_pthread_setspecific_ptr(THR_THD,...) client/completion_hash.cc: Updated call to init_alloc_root() client/mysql.cc: Updated call to init_alloc_root() client/mysqlbinlog.cc: init_dynamic_array() -> my_init_dynamic_array() Updated call to init_alloc_root() client/mysqlcheck.c: Updated call to my_init_dynamic_array() client/mysqldump.c: Updated call to init_alloc_root() client/mysqltest.cc: Updated call to init_alloc_root() Updated call to my_init_dynamic_array() Fixed compiler warnings extra/comp_err.c: Updated call to my_init_dynamic_array() extra/resolve_stack_dump.c: Updated call to my_init_dynamic_array() include/hash.h: Added HASH_THREAD_SPECIFIC include/heap.h: Added flag is internal temporary table. include/my_dir.h: Safety fix: Ensure that MY_DONT_SORT and MY_WANT_STAT don't interfer with other mysys flags include/my_global.h: Changed type of myf from int to ulong, as this is always a set of bit flags. include/my_sys.h: Added MY_THREAD_SPECIFIC and MY_THREAD_MOVE Added malloc_flags to DYNAMIC_ARRAY Added extra mysys flag argument to my_init_dynamic_array() Removed deprecated functions init_dynamic_array() and my_init_dynamic_array.._ci Updated paramaters for init_alloc_root() include/my_tree.h: Added my_flags to allow one to use MY_THREAD_SPECIFIC with hash tables.

So --plugin-load can be considered a composite option consisting of resetting the plugin load list and then calling --plugin-load-add to process the argument. Note that the order in which you specify --plugin-load and --plugin-load-add is important : "--plugin-load=x --plugin-load-add=y" will be equivalent to "--plugin-load=x,y" whereas "--plugin-load-add=y --plugin-load=x" will be equivalent to "plugin-load=x". Incompatible change : the --help --verbose command will no longer print the --plugin-load variable's values (as it doesn't have one). Otherwise both --plugin-load and --plugin-load-add are mentioned in it.	13 years ago

Aditya A	7a8c93e6dd	Bug#14234028 - CRASH DURING SHUTDOWN WITH BACKGROUND PURGE THREAD Analysis --------- my_stat() calls stat() and if the stat() call fails we try to set the variable my_errno which is actually a thread specific data . We try to get the address of this thread specific data using my_pthread_getspecifc(),but for the purge thread we have not defined any thread specific data so it returns null and when dereferencing null we get a segmentation fault. init_available_charsets() seen in the core stack is invoked through pthread_once() .pthread_once is used for one time initialization.Since free_charsets() is called before innodb plugin shutdown ,purge thread calls init_avaliable_charsets() which leads to the crash. Fix --- Call free_charsets() after the innodb plugin shutdown,since purge threads are still using the charsets.	13 years ago

That's why this test shows "NONE" index file writes in MySQL and "MANY" in MariaDB. mysql-test/suite/perfschema/r/server_init.result: MariaDB initializes the "manager" resources from the "manager" thread, and starts this thread only when --flush-time is not 0. MySQL 5.6 initializes "manager" resources unconditionally on server startup. mysql-test/suite/perfschema/r/stage_mdl_global.result: this differs, because MariaDB disables query cache when query_cache_size=0. MySQL does not do that, and this causes useless mutex locks and waits. mysql-test/suite/perfschema/r/statement_digest.result: md5 hashes of statement digests differ, because yacc token codes are different in mariadb mysql-test/suite/perfschema/r/statement_digest_consumers.result: md5 hashes of statement digests differ, because yacc token codes are different in mariadb mysql-test/suite/perfschema/r/statement_digest_long_query.result: md5 hashes of statement digests differ, because yacc token codes are different in mariadb mysql-test/suite/rpl/r/rpl_mixed_drop_create_temp_table.result: will be updated to match 5.6 when alfranio.correia@oracle.com-20110512172919-c1b5kmum4h52g0ni and anders.song@greatopensource.com-20110105052107-zoab0bsf5a6xxk2y are merged mysql-test/suite/rpl/r/rpl_non_direct_mixed_mixing_engines.result: will be updated to match 5.6 when anders.song@greatopensource.com-20110105052107-zoab0bsf5a6xxk2y is merged	13 years ago

Jon Olav Hauglid	58de166062	Bug#14621627 THREAD CACHE IS UNFAIR When a client connects to a MySQL server, first a THD object is created. If there are any idle server threads waiting, the THD object is then added to a list and a server thread is woken up. This thread then retrieves the THD object from the list and starts executing. The problem was that this list of THD objects waiting for a server thread, was not working in a FIFO fashion, but rather LIFO. This is unfair, as it means that the last THD added (=last client connected) will be assigned a server thread first. Note however that for this to be a problem, several clients must be able to connect and have THD objects constructed before any server threads manages to be woken up. This is not a very likely scenario. This patch fixes the problem by changing the THD list to work FIFO rather than LIFO. This is the 5.1/5.5 version of the patch.	13 years ago
