python - Fabric counter to display how many host are done -

i'm trying create counter able display "host 5/100 done" @ end of task. have counter classe :

class threadcounter(object):    def __init__(self, initval=0):       self.val =int(initval)       self.lock = threading.lock()    def increment(self):       self.lock:          self.val += 1   def value(self):       self.lock:          return self.val 

i tried few things make work : in main function, call task giving counter argument

def main():   my_counter = threadcounter(0)   execute(the_task,my_counter) @parallel def the_task(counter):   try:     do---my--stuff   :     my_counter.increment()     print my_counter.value() 

the counter @ "1" when displayed. feel counter wasn't shared.

i tried declare counter global same result. last try giving lock the_task , in the_task:

with lock :   counter += 1   print counter 

what should share counter between same fabric tasks ? i'm new threads in python. (i use python 2.6 (not willingly))

you can use decorator track task completion like,

total = 100 count = 0  def counter(f):     def wrapped(*args, **kwargs):         globals()["count"] += 1         ret = f(*args, **kwargs)         print "host %(count)s/%(total)s done" % globals()         return ret     return wrapped  @counter def first_task(counter):     # do---my--stuff     pass  @counter def second_task(counter):     # do---my--stuff     pass
