SequentialGeventHandler with DataWatch and ChildrenWatch

[arpanshah29]

In my main thread I try to set up a DataWatch and a ChildrenWatch as follows. I have not put all the args since this is just to demonstrate the issue:

seq.py

class Test(object):
    def __init__(self, hosts):
        self.hosts = hosts
        self.foo_count = 0
       self.bar_count = 0
        self.zkclient = KazooClient(hosts=self.hosts,
                                         handler=SequentialGeventHandler())
       self.zkclient.ChildrenWatch("/foo", self.foo_func)
       self.zkclient.DataWatch("/foo/bar",  self.bar_func)

   def foo_func(self):
        self.foo_count += 1

   def bar_func():
       self.bar_count += 1

Within zookeeper I have a node "/foo/bar"

I then have a script that just instantiates the Test object and does the following in a loop

test.py:

from seq import Test
from time import sleep

test = Test("localhost:2181")
while True:
     test.sleep(5)
     print test.foo_count
     print test.bar_count

When I run test.py and change the values of /foo/bar, I don't see the value of foo_count and bar_count incrementing. I.e both counts remain 1 no matter how many times I change "/foo/bar" or add children to "/foo".

It works as expected when I run it with the Threaded handler. I am unsure why and would appreciate help in figuring out why that is the case. Also it would be great to see a working example of the SequentialGeventHandler with the watch recipes. Thanks and apologies in advance if this is not the right forum for concerns like this one
