duplicate and or missing revisions in changes feed
--------------------------------------------------
Key: COUCHDB-763
URL: https://issues.apache.org/jira/browse/COUCHDB-763
Project: CouchDB
Issue Type: Bug
Components: Database Core
Affects Versions: 0.10.1
Reporter: Randall Leeds
Priority: Critical
I have no idea if this is unique to 0.10.1 or if it shows up on 0.11/trunk
since I have no clue how to repro.
If we can identify why this happens we should work to be very sure it's fixed.
I see something like the following in my changes feed (taken from consecutive
lines of an actually changes feed):
{"seq":36527,"id":"anonymized_docid","changes":[{"rev":"2186-967dbcd9d960b77955fcf6048fb219cc"}]},
{"seq":36530,"id":"anonymized_docid","changes":[{"rev":"2188-ae8481b29fd3a42d5190aba7c13a522b"}]},
I was under the impression that _changes only showed the newest revision for
any document.
Furthermore, the first of these two is actually missing. Querying the document
with ?revs_info=true shows it as such and this is confirmed by trying to query
for ?rev=2186-967dbcd9d960b77955fcf6048fb219cc
1) Missing revisions should never show up in changes
2) Changes shouldn't list a document twice
3) This makes replication impossible since the reader tries to open missing
revisions.
Mostly for number (3) I'm marking this as critical.
