Before the patch, slaves only appear in the output of SHOW SLAVE HOSTS when report-host option is set. If an expected slave does not appear in the list, nobody knows whether the slave does not connect or has started without the "report-host" option. The output also contains a strange field "Rpl_recovery_rank" which has never been implemented and the manual of MySQL5.4 declares that the field has been removed from MySQL5.4. This patch is done with these, According to the manual of MySQL5.4, "Rpl_recovery_rank" is removed. Slaves will register themselves to master no matter if report_host option is set or not. When slaves are registering themselves, their Server_ids, report_host and other information are together sent to master. Sever_ids are never null and is unique in one replication group. Slaves always can be identified with different Server_ids no matter if report_host exists.

Add an option to control whether the master should keep waiting until timeout when it detected that there is no semi-sync slave available. The bool option 'rpl_semi_sync_master_wait_no_slave' is 1 by defalt, and will keep waiting until timeout. When set to 0, the master will switch to asynchronous replication immediately when no semi-sync slave is available.

Semi-sync status were not reset by FLUSH STATUS, this was because all semi-sync status variables are defined as SHOW_FUNC and FLUSH STATUS could only reset SHOW_LONG type variables. This problem is fixed by change all status variables that should be reset by FLUSH STATUS from SHOW_FUNC to SHOW_LONG. After the fix, the following status variables will be reset by FLUSH STATUS: Rpl_semi_sync_master_yes_tx Rpl_semi_sync_master_no_tx Note: normally, FLUSH STATUS itself will be written into binlog and be replicated, so after FLUSH STATS, one of Rpl_semi_sync_master_yes_tx Rpl_semi_sync_master_no_tx can be 1 dependent on the semi-sync status. So it's recommended to use FLUSH NO_WRITE_TO_BINLOG STATUS to avoid this.

Errors when send reply to master should never cause the IO thread to stop, because master can fall back to async replication if it does not get reply from slave. The problem is fixed by deliberately ignoring the return value of slaveReply.

Semi-sync uses an extra connection from slave to master to send replies, this is a normal client connection, and used a normal SET query to set the reply information on master, which is visible to user and may cause some confusion and complaining. This problem is fixed by using the method of sending reply by using the same connection that is used by master dump thread to send binlog to slave. Since now the semi-sync plugins are integrated with the server code, it is not a problem to use the internal net interfaces to do this. The master dump thread will mark the event requires a reply and wait for the reply when the event just sent is the last event of a transaction and semi-sync status is ON; And the slave will send a reply to master when it received such an event that requires a reply.

The issue appears when number of heartbeat events non-zero before start of test block. But really we need to check that no new events has received during test block. So I did following: 1. Replace absolute values by diff of values 2. Increase heartbeat period from 1.5 to 5 sec

CHANGE MASTER TO command required the value for RELAY_LOG_FILE to be an absolute path, which was different from the requirement of MASTER_LOG_FILE. This patch fixed the problem by changing the value for RELAY_LOG_FILE to be the basename of the log file as that for MASTER_LOG_FILE.

Options loaded from config files were added before command line arguments, and they were parsed together, which could interprete the following: option-a option-b as --option-a=--option-b if 'option-a' requires a value, and caused confusing. Because all options that requires a value are always given in the form '--option=value', so it's an error if there is no '=value' part for such an option read from config file. This patch added a separator to separate the arguments from config files and that from command line, so that they can be handled differently. And report an error for options loaded from config files that requires a value and is not given in the form '--option=value'.

There were two memory leaks in mysqlbinlog command, one was already fixed by previous patches, another one was that defaults_argv was set to the value of argv after parse_args, in which called handle_options after calling load_defaults and changed the value of argv, and caused the memory allocated for defaults arguments not freed. Fixed the problem by setting defaults_argv right after calling load_defaults.

There are three internal status for slave I/O thread, both MYSQL_SLAVE_RUN_NOT_CONNECT and MYSQL_SLAVE_NOT_RUN are reported as 'No' for Slave_IO_running of command SHOW SLAVE STATUS. Change MYSQL_SLAVE_RUN_NOT_CONNECT to be reported as 'Connecting'.

When a storage engine failed to initialize before allocated slot number, the slot number would be 0, and when later finalizing this plugin, it would accidentally unplug the storage engine currently uses slot 0. This patch fixed this problem by add a new macro value HA_SLOT_UNDEF to distinguish undefined slot number from slot 0.

NOTE: Backporting the patch to next-mr. The slave was crashing while failing to execute the init_slave() function. The issue stems from two different reasons: 1 - A failure while allocating the master info structure generated a segfault due to a NULL pointer. 2 - A failure while recovering generated a segfault due to a non-initialized relay log file. In other words, the mi->init and rli->init were both set to true before executing the recovery process thus creating an inconsistent state as the relay log file was not initialized. To circumvent such problems, we refactored the recovery process which is now executed while initializing the relay log. It is ensured that the master info structure is created before accessing it and any error is propagated thus avoiding to set mi->init and rli->init to true when for instance the relay log is not initialized or the relay info is not flushed. The changes related to the refactory are described below: 1 - Removed call to init_recovery from init_slave. 2 - Changed the signature of the function init_recovery. 3 - Removed flushes. They are called while initializing the relay log and master info. 4 - Made sure that if the relay info is not flushed the mi-init and rli-init are not set to true. In this patch, we also replaced the exit(1) in the fault injection by DBUG_ABORT() to make it compliant with the code guidelines.

rpl_slave_skip fails randomly on PB2. This patch fixes the failure by setting explicit wait for SQL thread to stop, instead of the wait_for_slave_to_stop mysqltest command, after a start until command is executed.
