0.0.29 Wed Jun 23, 2010 2:50 pm
- fix some broken test cases
- always use a temporary directory for test case pid/log files
0.0.28 Tue Jun 22, 2010 11:10 pm
- fix for bug where is_running() called immediately after start() returned false
- write child pidfile in parent process on fork()
- child process might not be forked instantly if system is busy
- prevents needing to cache the pid
- gets ugly since multiple processes might be attempting to control the same daemon
- warning: two processes calling start() at exactly the same time could still start two daemons
- still working on a fix
0.0.27 Tue Jun 22, 2010 10:45 pm
- remove required class 'Proc::Launcher::Supervisor' on Proc::Launcher::Manager's supervisor object
- tweak sleep times on a few test cases
- warning: child process may return false if is_running() called immediately following start()
- child process may not have written pid file yet
- considering another fix for this involving caching the pid from fork()
0.0.26 Sat Dec 5, 2009 5:02 am
- adjusting sleep times in test cases
- consistently sleep a few seconds after start() and stop() before is_running()
- pid is no longer being cached, need to wait for child process has forked and written pidfile
- generally happens very quickly but might take a few seconds on slower machines
0.0.25 Sat Dec 5, 2009 3:59 am
- API CHANGES:
- read_pid() is now pid()
- pid attribute removed, now call $obj->pid() instead of $obj->pid
- no longer caches pid in Proc::Launcher
- resolves a bug where supervisor thinks a process was shut down and starts a second one
- adjust some sleep times in the test cases to pass more reliably in my vm
0.0.24 Sun Nov 22, 2009 12:07 am
- create optional named pipe attached to STDIN of forked process
- must be enabled, default is to not create the named pipe
- forked process calls stopped() on exit to remove pidfile/named pipe
- cleaned up some of the leaky abstraction issues with is_running()
- check if pid owned by another user
- catches some cases where a pid that has been recycled
- update $0 in forked processes to include 'perl - Proc::Launcher'
- makes forked processes easy to identify
0.0.23 Wed Nov 11, 2009 1:54 am
- resolve a bug where multiple Launchers try to start the same daemon at the same time
- added simple rename-based lock to write_pid() method
0.0.20 Sun Nov 8, 2009 6:37 pm
- adding reports for Devel::Cover and Perl::Metrics::Simple
- increased test coverage to 92%
- improvements for launching processes with a named class, method, and context
- more test cases
- more debugging output
- several improvements to tail() in panctl, manager, and launcher
- launched processes now call setsid
- improvements to manager
- start() method returns number of daemons started
- testing enable() and disable()
- launcher restart() method now accepts number of seconds to sleep
- updated docs with the details
0.0.19 Tue Nov 3, 2009 11:27 pm
- manager's spawn() method renamed register()
- spawn() was misleading since it doesn't actually start a process

- added methods to enable/disable daemons
- daemon won't perform start() if disabled
- supervisor doesn't start() a daemon that is disabled
- no longer have to restart the supervisor to change the active daemon list
- disable() touches a file, enable() removes it
- daemon_name.disabled, next to daemon_name.{pid,log}
0.0.17 Tue Oct 27, 2009 2:30 am
- added docs for panctl
0.0.16 Mon Oct 26, 2009 10:09 pm

- reopen STDIN to /dev/null rather than closing it in forked process
- allow start/stop/force_stop methods to be called on supervisor
- manager API change for the supervisor, see POD docs
0.0.15 Sun Oct 25, 2009 6:14 pm
