Subject [jira] [Commented] (COUCHDB-1163) Document returned by id, but cannot be found by rev
Date Wed, 18 May 2011 15:22:47 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1163?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13035433#comment-13035433
] 

Clare Walsh commented on COUCHDB-1163:
--------------------------------------

If the doc is supposed to be deleted then deleted is what we want, we don't want to bring
it back to life, just get it into its correct state and make replication not fail on it...

Is the consensus that they were deleted but the wrong revision was winning because of a bug
in the tree making it look not deleted?

(Am about to try replicating the compacted and therefore corrected database...)

> Somehow, our cluster has developed the following problem on a handful of documents. Will
post reproduction steps if we find them. All properties have been redacted. All the documents
this affects also have attachments, if that is significant. Once a document is in this situation,
it causes conflict detection, replication and include_docs to behave incorrectly or outright
fail.
