unknown	31a5edb5c2	MDEV-4506: Parallel replication. Intermediate commit. Hook in the wait-for-prior-commit logic (not really tested yet). Clean up some resource maintenance around rpl_group_info (may still be some smaller issues there though). Add a ToDo list at the top of rpl_parallel.cc	13 years ago

unknown	7e5dc4f074	MDEV-4506: Parallel replication. Intermediate commit. Implement facility for the commit in one thread to wait for the commit of another to complete first. The wait is done in a way that does not hinder that a waiter and a waitee can group commit together with a single fsync() in both binlog and InnoDB. The wait is done efficiently with respect to locking. The patch was originally made to support TaoBao parallel replication with in-order commit; now it will be adapted to also be used for parallel replication of group-committed transactions. A waiter THD registers itself with a prior waitee THD. The waiter will then complete its commit at the earliest in the same group commit of the waitee (when using binlog). The wait can also be done explicitly by the waitee.	13 years ago

unknown	7ad47ab0e0	MDEV-4605: Failing to load GTID slave position from rpl.gtid_slave_pos There were several cases where the slave GTID position was not loaded correctly before being used. This caused various failures such as corrupting the position at slave start and empty values of @@gtid_slave_pos and @@gtid_current_pos. Fixed by adding more checks for loaded position, and by always loading the position at server startup.	13 years ago
unknown	ee2b7db3f8	MDEV-4478: Implement GTID "strict mode" When @@GLOBAL.gtid_strict_mode=1, then certain operations result in error that would otherwise result in out-of-order binlog files between servers. GTID sequence numbers are now allocated independently per domain; this results in less/no holes in GTID sequences, increasing the likelyhood that diverging binlogs will be caught by the slave when GTID strict mode is enabled.	13 years ago

Sergei Golubchik	3aa50f64bb	MDEV-4505 Buffer overrun when processing --log-bin parameter without file name because --log-bin sets opt_bin_logname to "" (same for any OPT_ARG GET_STR (or GET_STR_ALLOC) option)	13 years ago
unknown	6b97512b21	Add missing check for thd->killed in mysql_binlog_send(). The slave dump thread running on the master only checked thd->killed whenever it reached the end of a binlog file, not between events. This could unnecessarily delay server shutdown. This was found by code inspection while tracking down some occasional "forcing close of thread..." errors in Buildbot. Hopefully this will fix the failures, but the fix is correct in any case. Also increase the wait during server shutdown, 2 seconds is a bit tight in case of heavy I/O stall, and it seems better to delay shutdown a bit than force-kill threads unnecessarily. Also fix some races in test cases that restart the mysqld server. The .expect file should be changed with --append_file, --remove_file + --write_file creates a short window where mysqld can error out due to .expect file missing.	13 years ago

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
