Not it works in a finite state machine-way. server-tools/instance-manager/guardian.h: Appropriate (to .cc) changes in the header + some comment added server-tools/instance-manager/instance.cc: added proxy thread to monitor instance. Two kinds of stop() now -- stop() and kill_instance which only sends a signal server-tools/instance-manager/instance.h: appropriate changes server-tools/instance-manager/instance_map.cc: cleanup server-tools/instance-manager/instance_map.h: cleanup server-tools/instance-manager/instance_options.cc: Caching of the pid-file-name is added. some comments added server-tools/instance-manager/instance_options.h: cleanup server-tools/instance-manager/listener.cc: listener my_thread_init added (though it doesn't use any mysys functions). Just in case server-tools/instance-manager/manager.cc: SIGCHLD handler removed. now instance monitoring is implemented through proxy threads. This is to work nicely with LinuxThreads server-tools/instance-manager/options.cc: added option to create a password file entry (this was implemented by Sergei Vojtovich) server-tools/instance-manager/parse.cc: inline function get_word moved to the header server-tools/instance-manager/parse.h: get_word moved here to use form parse_output server-tools/instance-manager/parse_output.cc: get_word() clone removed. now looking through the output linewise server-tools/instance-manager/protocol.cc: Buffer error chech added server-tools/instance-manager/user_map.cc: typo fixed

Behaviour of the guardian in case of the instance crash has changed. Now it tries to restart an instance constantly in the first 2 seconds after the crash was noticed, and then it tries restart an instance once in the MONITORING_INTERVAL. If it failed to restart instance for "restart_retry" (compiled-in value) times, guardian stops trying to restart it. server-tools/instance-manager/guardian.h: Several new functions and variables declared. server-tools/instance-manager/instance.cc: now start doesn't call stop(), but rather tries to remove the pidfile itself server-tools/instance-manager/instance.h: cleanup server-tools/instance-manager/instance_map.cc: no more "admin" options server-tools/instance-manager/instance_map.h: User and password purged from instance_map options, as IM shouldn't know them server-tools/instance-manager/instance_options.cc: new option added -- shutdown_delay, guarded option now called nonguaded and has the opposite meaning server-tools/instance-manager/instance_options.h: appropriate changes, reflecting options addition/removal server-tools/instance-manager/manager.cc: shutdown process is complicated a bit -- at first signal thread should stop guardian, and only then the IM itself server-tools/instance-manager/messages.cc: update error message server-tools/instance-manager/options.cc: admin user/password purged from mysqlmanager options

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
