Subject [jira] [Commented] (JCR-3629) [jcr2spi]RepositoryException lost in org.apache.jackrabbit.jcr2spi.ItemManagerImpl while querying on remote nodes exposed by jackrabbit-spi
Date Thu, 25 Jul 2013 12:55:49 GMT

    [ https://issues.apache.org/jira/browse/JCR-3629?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13719588#comment-13719588

Chetan Mehrotra commented on JCR-3629:
--------------------------------------

>jcr2spi doesn't run any test. please run a complete build of all of jackrabbit with -PintegrationTesting.
this will run all tests for all jcr2spi - spi2something setup scenarios present in jackrabbit
core including the jcr-remoting.

Did not realized that. Would run test from the top.

>regarding public and non-public API: you kept struggling with that distinction in the
past when adding functionality to sling that used internal, non-public API.
it's very simple: everything in jackrabbit-api and jackrabbit-spi is public API everything
else is internal API and may change any time. 
Got it. Would follow that as a thumb rule!!

> The catch block for RepositoryException should probably wrap the exception as a RuntimeException
as it might happen for unknown reason.
> Changing this might break backward compatibility. 
> The issue was detected when trying to implement a synchronization service with a content
repository exposed by a jackrabbit-spi implementation. If the content repository becomes non-responsive
while checking whether a node exists or not, the RepositoryException is lost in ItemManager#nodeExists
resulting in deletion of the local node corresponding to the remote node.
