0.0.31 Fri Apr 15, 2011 9:09pm

• adding some additional debugging for failures on MirBSD and OpenBSD
• updating dzil.ini, no longer works with current version of Dist-Zilla
• resolve locking bug that can result in multiple instances of a daemon being started
  • launcher's start() method may now return undef if child exits immediately or takes a long time to fork()

0.0.30 Thu Jun 24, 2010 7:46 pm

• fixing one more broken test missed in previous release
  • use a temporary directory for pid/log files

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

• launched processes now call setsid
• improvements to manager
