> Documentation for Lock recipe has major flaw
> --------------------------------------------
>
> Key: ZOOKEEPER-1262
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1262
> Project: ZooKeeper
> Issue Type: Bug
> Components: documentation
> Affects Versions: 3.3.3
> Reporter: Jordan Zimmerman
> Attachments: patch.txt, recipes.diff, recipes.html
>
>
> The recipe for Locks documented here:
> http://zookeeper.apache.org/doc/trunk/recipes.html#sc_recipes_Locks doesn't
> deal with the problem of create() succeeding but the server crashing before
> the result is returned. As written, if the server crashes before the result
> is returned the client can never know what sequential node was created for
> it. The way to deal with this is to embed the session ID in the node name.
> The Lock implementation in the ZK distro does this. But, the documentation
> will lead implementors to write bad code.
