      Bug #19059: Failure to get version information when running from source tree · 11099ed5
      unknown authored
        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).
      
      
      server-tools/instance-manager/instance_options.cc:
        Look for 'Ver' to get version from running mysqld --version
      server-tools/instance-manager/parse_output.cc:
        Make parse_output_and_get_value() look at the whole line to find
        the word, instead of just at the beginning of each line.
      sql/mysqld.cc:
        Note that the instance manager relies on 'Ver' in mysqld --version

        Delete: server-tools/instance-manager/factory.cc
      server-tools/instance-manager/Makefile.am:
        - remove Commands_factory: it'll be needed when we add support
        for NNTP/HTTP connections, currently it only adds unnecessary
        complexity.
      server-tools/instance-manager/commands.cc:
        - fix coding style: no else after return; fix comments, make
        one place a bit faster.
      server-tools/instance-manager/guardian.cc:
        - fix coding style and comments.
        - we must register the current thread in the thread registry
          before entering pthread_cond_timedwait, because at shutdown
          the thread registry will try to kick out of wait all blocked 
          threads. Unregistered threads are not awakened by the registry. 
          This fixes the failinig assert in Thread_registry::~Thread_registry
          at shutdown, when shutdown is requested and there is an
          instance monitored by Guardian.
      server-tools/instance-manager/guardian.h:
        - fix coding style: enums must start with enum_
      server-tools/instance-manager/instance.h:

      server-tools/instance-manager/instance_map.cc:

      server-tools/instance-manager/mysql_connection.cc:
        - remove Commands_factory
      server-tools/instance-manager/options.cc:
        - fix a possible crash when the instance manager is started with
        --no-defaults --defaults-file=~/.my.cnf: if we return
        without cloning saved_argv by calling load_defaults, Options::cleanup
        will crash on attempt to free_defaults(saved_argv);
      server-tools/instance-manager/parse.cc:
        - get rid of Commands_factory
      server-tools/instance-manager/parse.h:
        - get rid of Commands_factory
      server-tools/instance-manager/parse_output.cc:
        - in parse_output_and_get_value return error also if the specified
          pattern was not found, or the command failed to execute.
      server-tools/instance-manager/portability.h:
        - fix coding style (// comments are allowed only at ends of lines)
      server-tools/instance-manager/thread_registry.cc:
        - implement Thread_registry::cond_timedwait
      server-tools/instance-manager/thread_registry.h:
        - implement Thread_registry::cond_timedwait; remove
          unused out parameter from Thread_registry::cond_wait.
      server-tools/instance-manager/user_map.cc:
        - safety: newline can take 2 bytes.

      IM mostly fixed according to Brian's directions. Will need to do some additional option handling and cleanups
      
      
      server-tools/instance-manager/Makefile.am:
        New file added
      server-tools/instance-manager/client_func.c:
        typo fixed
      server-tools/instance-manager/commands.cc:
        there are no admin-user snd admin-password fields anymore, so no need to show their values
      server-tools/instance-manager/guardian.cc:
        Syncronization added -- now guardian wakes up whenever SIGCLD has been catched
      server-tools/instance-manager/guardian.h:
        Condition variable declared
      server-tools/instance-manager/instance.cc:
        Persistent connection to the instance removed. Now we use SIGTERM instead of com_shutdown for STOP. We also
        manage SIGCHLD ourselves now (therefore no double fork).
      server-tools/instance-manager/instance.h:
        Pointer to the instance_map added, MySQL connection structures removed
      server-tools/instance-manager/instance_map.cc:
        More syncronization added (to make proper STOP)
      server-tools/instance-manager/instance_map.h:
        added condition variable and mutex for connection threads to wait for SIGCHLD
      server-tools/instance-manager/instance_options.cc:
        defaults-handling methods have been added.
      server-tools/instance-manager/instance_options.h:
        New functions and constants declared
      server-tools/instance-manager/listener.cc:
        No changes here (bk bug?)
      server-tools/instance-manager/manager.cc:
        SIGCHLD handling added
