Alik's patch for BUG#22306: STOP INSTANCE can not be applied for
instances in Crashed, Failed and Abandoned" to ease review process.
Evaluate global variable linuxthreads before starting threads to avoid
a race.
Fixed some possible fatal wrong arguments to printf() style functions
Initialized some not initialized variables
Fixed bug in stored procedure and continue handlers
(Fixes Bug#22150)
Remove race situations that occur when removing pidfiles. Primarily each process should remove its own
pidfile, secondly it should be removed by the process that created it and _only_ if it's
certain the process is dead. Third, mysql-test-run.pl will remove the pidfile when process has been killed.
- Set state of an instance to STARTING _before_ calling instance->start()
- Check that pidfile of instance has been created before changing STARTING => STARTED
- Only remove the pidfile if IM kills an instance with SIGKILL, otherwise the instance will remove it itself
The problem was a call to convert_dirname() with a destination buffer
that did not have room for the trailing slash added by that function.
This could cause the instance manager to crash in some cases.
- WL#3158: IM: Instance configuration extensions;
- WL#3159: IM: --bootstrap and --start-default-instance modes
The following new statements have been added:
- CREATE INSTANCE;
- DROP INSTANCE;
The behaviour of the following statements have been changed:
- SET;
- UNSET;
- FLUSH INSTANCES;
- SHOW INSTANCES;
- SHOW INSTANCE OPTIONS;
- Add function "mysqld_real_path" which is needed if the mysqld_path is a symlink or a script(like libtool) that executes the real mysqld.
- Add new variable mysqld_real_path
- Use mysqld_real_path from fill_instance_version
Fix the way that instance manager finds the version number of instances,
so that it works properly when the executable name isn't the same as what
the instance-manager launched, such as when wrapping a libtool-wrapped
executable from the source tree.
This removes the 'Ver ' reported in the version column output by
'SHOW INSTANCE STATUS ...', but the format of this column is not
documented (and is pretty free-form to begin with).
