tracd doesn't create PID file and crash if try to start with --pidfile option

[kvt@…]

If try to start tracd with —pidfile option and PID-file is not exists you will see error message: "Error writing to pid file: …"

This problem occurs because in trac.util.daemon doesn't try create PID file if it not exist but try opening for read.

This problem can be fixed if make changes in trac/util/daemon.py (lines 26-44)

        pidfile = os.path.abspath(pidfile)
	if os.path.exists(pidfile):
	  with open(pidfile) as fileobj:
	    try:
	      pid = int(fileobj.read())
	    except ValueError:
	      sys.exit('Invalid PID in file %s' % pidfile)
	
	    try: # signal the process to see if it is still running
	      os.kill(pid, 0)
	      if not progname:
	      progname = os.path.basename(sys.argv[0])
	      sys.exit('%s is already running with pid %s' % (progname, pid))
	    except OSError, e:
	      if e.errno != errno.ESRCH:
	      raise
	else:
            fileobj = open(pidfile, 'w')
            fileobj.close()
