Re: Metakit DB Synchronizing (Python)

I don't seem to have this problem.  Attached is some simple test code,
two threads are started, one thread modifies the view and one thread
just calls metakit.dump on the view.  Take a look and see if you are
doing anything drastically different:

import time, threading, whrandom
import metakit
st = metakit.storage()
vw = st.getas("test[a,b,c]")
for i in range(10):
   vw.append(("%ia"%i, "%ib"%i, "%ic"%i))

class MyThread(threading.Thread):
   def __init__(self, st, alter=False):
       threading.Thread.__init__(self)
       self.vw = st.view("test")
       self.alter = alter

   def run(self):
       iterations = 10
       count = 1000
       for i in range(iterations):
           if self.alter:
               for i in range(len(self.vw)):
                   self.vw[i].a = str(count)
               count += 1
           else:
               metakit.dump(self.vw)
           time.sleep(1)
       print self.getName(), "is DONE"

if __name__ == '__main__':
   threadList = []

   # Create 5 MyThread() threads
   threadList.append(MyThread(st, alter=True))
   threadList.append(MyThread(st, alter=False))

   # Start all threads
   for thread in threadList:
       thread.start()

   # As long as we have more than just the 'main' thread running, print
   # out a status message
   while threading.activeCount() > 1 :
       print str(threading.activeCount()), "threads running incl. main"
       time.sleep(1)
