Python open and kill subprocess -


i'm working on widnows 7 (32 bits) , code:

def start_mviewer_broker(broker_path, test_name): """ function starts broker server""" try:     print("**** start_mviewer_broker ****")     p = subprocess.popen('start python ' + broker_path + ' ' + test_name, shell=true)     return p except:     print("**** start_mviewer_broker - exception ****")     return 0   def kill_process(p): """ function kills input running process""" try:     print("**** kill_process ****")     p.terminate() except:     print("**** kill_process - exception ****")     pass

i have few of problems. way launch subprocess shell=true option. if change option false subprocess not launched.

other problem kill process doesn't kill process not exception raised.

any idea?

you want change code following:

def start_mviewer_broker(broker_path, test_name): """ function starts broker server""" try:     print("**** start_mviewer_broker ****")     return subprocess.popen('python ' + broker_path + ' ' + test_name) # note changed line here except:     print("**** start_mviewer_broker - exception ****")     return 0   def kill_process(p): """ function kills input running process""" try:     print("**** kill_process ****")     p.terminate() except:     print("**** kill_process - exception ****")     pass

the start part running not necessary. in fact, not executable cmd command. hence, requires shell run. why wasn't working shell=false. however, upon removing it, can use shell=false. have python process returned process instead of shell used spawn it. killing python process want do, not shell, after removing start part, have kill_process() code working properly.

btw, shell=false default subprocess.popen() , has been left out in above code. also, setting p process , returning seems waste of line of code. can shortened returning directly (as shown in above code).
