> Patch for external project it.could.webdav
> ------------------------------------------

>                 Key: HADOOP-505
>                 URL: http://issues.apache.org/jira/browse/HADOOP-505
>             Project: Hadoop
>          Issue Type: Task
>          Components: dfs
>            Reporter: Michel Tourn

> Context: 
> http://issues.apache.org/jira/browse/HADOOP-496
> http://could.it/main/a-simple-approach-to-webdav.html
> This patch applies to an external project that Hadoop would use as a library.
> You can obtain the baseline code:
> svn co --revision {"1 Sep 2006 00:00:00 GMT"} http://could.it/repo/webdav/head/
> Then apply the attached patch.
> Patch details below.
> ---------------------
> Changes in the patch are:
> Filehandle leaks prevented it from working on Windows. (in.close() in 3 places)
> Filehandle leaks would eventually crash server on Linux.
> Now it passes the litmus compliance tests, in both original and HDFS mode.
> Mostly had to refine the HTTP status codes.
> Decoupled COPY and MOVE
> This allows an implementation of MOVE other than COPY-and-delete
> There is no new "abstraction code" to support a distributed filesystem backend.
> Only: one change to make a java.io.File reference work when it represents a 
> non-Windows path on Windows: (unixAbsolute = rootPath.startsWith("/"))
> The factory code via servlet properties was extended to allow loading by name:
> repositoryClass="it.could.webdav.DAVRepository"
> repositoryClass="it.could.webdav.XMLRepository"
> repositoryClass="org.apache.hadoop.dfs.webdav.HDFSRepository"
> 4 classes are subclassed for the alternative implementation:
> A few private fields were made protected.
> Some constructor logic moved to protected init() method-s so it can be overriden.
