Subject [jira] Commented: (ZOOKEEPER-679) Offers a node design for interacting with the Java Zookeeper client.
Date Sun, 09 May 2010 02:02:49 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12865526#action_12865526

Aaron Crow commented on ZOOKEEPER-679:
--------------------------------------

Hi Chris, my apologies, I haven't had much time to continue with this patch. I kind of got
held up by the combination of limited time, and apparently being required to engineer a standalone
build for the patch. 

This is actually my first significant contribution, so I'm feeling a little lost at this point.
Is it kosher to move patches out of zk contrib and into independent repos? And what would
make it easer to collaborate on in github vs. the main zk project?

Many thanks for your interest and time...

Aaron

> 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.
