增强使用说明

Hi, you can put the script above to a file called
Karrgiell_multiprocess.py , and then double click it to run Karrigell
Server with many process instances which are all running at the same
tcp port.

As we all know, Karrigell handle custom's request one by one, so one a
long-running script is executing, other request seams to be blocked .

Now, there is no problem about that with the power of pyprocessing


> def main_start():
>     # Launch the server
>     port = 8086
#~~~~~~~~~~~~~~ ,here is the port your server will listen to
>     process_num = 3
#~~~~~~~~~~~~~~, here is how many process instances to serve

特别修订

modification of a Karrigell's file "core/k_config.py".:

in line 44:

try:
   _opts, _args = getopt.getopt(sys.argv[1:], "hP:L:SR",['processing-
fork'])

#~~~~~~~~~~~~~ here
   print _opts,_args
except getopt.GetoptError:
   # print usage information and exit:
   usage()
   raise

• I am not familiar with pyprocessing, I found that the child process

forked lost the arguments of their parent process, and they had their own arguments in sys.argv ('processing-fork' and a process id).

• However, it's an ugly way to solve the problem. If some one has better

idea, tell me please.

You are aware you can get multiprocess Karrigell by using mod_wsgi?
