asssertion failed [fileRev] at ep-engine/src/couch-kvstore/couch-kvstore.cc:1823

Description

Pre-analysis shows that persistence engine was requested to store a document, and internal table had a file revision of 0 to relevant vbucket.
This is clearly violation of invariant, since fileRev in data/$bucket/$vbid.couch.$fileRev is numbered with 1 and is ever-growing.

On a first glance, invariant is carefully maintained.
Yet it somehow got violated in our setup.

Oh, I see it's lower now:
https://github.com/couchbase/manifest/blob/master/released/3.1.0.xml
And this issue is listed/linked in
https://couchbasecloud.atlassian.net/browse/MB-14772
so probably it made it through.
And then just relnotes are incomplete..

I did try to check "the old way" by looking at manifest file here...
https://github.com/couchbase/manifest
...but I don't see 3.1.0 manifest there.

Things have changed?

Alexander Petrossian (PAF) September 15, 2015 at 11:35 AM

Friends, thanks for fixing this.
Question: 3.1.0 relnotes here: http://docs.couchbase.com/admin/admin/rel-notes/rel-notes3.0.html
Do not this bug among those fixed.
Do we take it that it made it to 3.1.0 binary?
