Subject [jira] [Commented] (OAK-5557) incomplete diffManyChildren during commitHook evaluation in a persisted branch
Date Wed, 01 Feb 2017 13:37:51 GMT

    [ https://issues.apache.org/jira/browse/OAK-5557?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15848379#comment-15848379

Marcel Reutegger commented on OAK-5557:
---------------------------------------

Hmm, maybe related to a rebase of the branch before commit hooks run and then the diff is
incorrect?

> In oak 1.2 when doing a diffManyChildren as part of running the CommitHooks as part of
a branch commit, not all child paths are taken into account in some cases.
> The problem seems to be related to the [{{_modified}} calculation|https://github.com/apache/jackrabbit-oak/blob/jackrabbit-oak-1.2.14/oak-core/src/main/java/org/apache/jackrabbit/oak/plugins/document/DocumentNodeStore.java#L2242]
when doing the query for affected child paths. It seems [that {{minValue}}|https://github.com/apache/jackrabbit-oak/blob/jackrabbit-oak-1.2.14/oak-core/src/main/java/org/apache/jackrabbit/oak/plugins/document/DocumentNodeStore.java#L2242]
is not correctly calculated when doing {{compareAgainstBaseState}} as part of a persisted
branch.
> Note that the problem can be reproduced very good on 1.2.14, less good but still on the
latest 1.2 and not in trunk (ie almost 1.6.0).
> Attaching a test case to reproduce
