Subject [jira] Commented: (ZOOKEEPER-679) Offers a node design for interacting with the Java Zookeeper client.
Date Sun, 09 May 2010 02:40:48 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12865527#action_12865527

Chris K Wensel commented on ZOOKEEPER-679:
------------------------------------------

Its more of a mater of what's more utilitarian. Your code can be locked up into the apache
repo where only mods must be submitted as patch files, or in github where people can branch/fork/merge
at will. 

note that some projects are doing away with contrib folders since most of the contributions
either become abandoned (partly because patch process is too onerous) or are very immature
and buggy.

the code is now in github, you can choose to fork it and modify it. or ignore it.

> Following up on my conversations with Patrick and Mahadev (http://n2.nabble.com/Might-I-contribute-a-Node-design-for-the-Java-API-td4567695.html#a4567695).
> This patch includes the implementation as well as unit tests. The first unit test gives
a simple high level demo of using the node API.
> The current implementation is simple and is only what I need withe current project I
am working on. However, I am very open to any and all suggestions for improvement.
> This is a proposal to support a simplified node (or File) like API into a Zookeeper tree,
by wrapping the Zookeeper Java client. It is similar to Java's File API design.
> Although, I'm trying to make it easier in a few spots. For example, deleting a Node recursively
is done by default. I also lean toward resolving Exceptions "under the hood" when it seems
appropriate. For example, if you ask a Node if it exists, and its parent doesn't even exist,
you just get a false back (rather than a nasty Exception).
> As for watches and ephemeral nodes, my current work does not need these things so I currently
have no handling of them. But if potential users of  the "Node a.k.a. File" design want these
things, I'd be open to supporting them as reasonable.
