Paul Kuruvilla created COUCHDB-3418:
---------------------------------------
Summary: _changes returns a single item that says a doc is deleted
Key: COUCHDB-3418
URL: https://issues.apache.org/jira/browse/COUCHDB-3418
Project: CouchDB
Issue Type: Bug
Components: HTTP Interface
Reporter: Paul Kuruvilla
I discovered this while working on maintaining a replica of the npm registry
(https://replicate.npmjs.com) for Gratipay (https://gratipay.com).
When I hit the {{/registry/_changes}} endpoint with a filter for {{doc_id =
'adam-test'}}, I get back a single change which says that the doc was deleted.
This looks like a bug, because I'd expect that every 'deleted' change would
have a corresponding change for when the doc was created. (Please correct me if
my understanding is wrong)
Here is a cURL command to replicate the issue:
{code}
curl -XPOST -H "Content-Type: application/json"
https://replicate.npmjs.com/registry/_changes\?limit\=10\&filter\=_doc_ids -d
'{"doc_ids": ["adam-test"]}'
{code}
The output I receive is:
{code}
{
"results": [
{"seq":1908160,"id":"adam-test","changes":[{"rev":"2-a543a8082c03a641a098fbe39e58afed"}],"deleted":true}
],
"last_seq":1916520
}
{code}
This was the first such occurrence we hit in the ~ 4 million changes that we've
processed.
