Subject [jira] Updated: (ZOOKEEPER-765) Add python example script
Date Fri, 09 Jul 2010 16:47:49 GMT

     [ https://issues.apache.org/jira/browse/ZOOKEEPER-765?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrei Savu updated ZOOKEEPER-765:
----------------------------------

    Attachment: ZOOKEEPER-765.patch

I have created a patch containing the script Travis wrote. I have also fixed some typos and
added more comments that explain how to play with it. 

I have also added a reference to zk-smoketest [1] because that's another good example that
shows how to use the python ZooKeeper client library.

> When adding some zookeeper-based functionality to a python script I had to figure everything
out without guidance, which while doable, would have been a lot easier with an example. I
extracted a skeleton program structure out with hopes its useful to others (maybe add as an
example in the source or wiki?).
> This script does an aget() and sets a watch, and hopefully illustrates what's going on,
and where to plug in your application code that gets run when the znode changes.
> There are probably some bugs, which if we fix now and provide a well-reviewed example
hopefully others will not run into the same mistakes.
