    - 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

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
