Glynn Bird created COUCHDB-2522:
-----------------------------------
Summary: CouchDB 2.0 /_changes feed does not return full
attachment data with attachments=true
Key: COUCHDB-2522
URL: https://issues.apache.org/jira/browse/COUCHDB-2522
Project: CouchDB
Issue Type: Bug
Security Level: public (Regular issues)
Components: Database Core
Reporter: Glynn Bird
In CouchDB 1.6, if a document is created with an attachment, and the _changes
feed is consumed with '?include_docs=true&attachments=true', the full
attachments are seen in the feed e.g.:
{Code}
$ curl -X DELETE http://127.0.0.1:5984/test
{"ok":true}
~$ curl -X PUT http://127.0.0.1:5984/test
{"ok":true}
~$ curl -X POST http://127.0.0.1:5984/test -H 'Content-type:application/json'
-d '{ "id": "bob", "_attachments": { "foo.txt": {"content_type":
"text/plain","data": "holy moly"} } }'
{"ok":true,"id":"6fb52c4798e6186baf9871ce19000a8d","rev":"1-8ccb83bd8362d56d396fb84e875dcae9"}
~$ curl

{"seq":1,"id":"6fb52c4798e6186baf9871ce19000a8d","changes":[{"rev":"1-8ccb83bd8362d56d396fb84e875dcae9"}],"doc":{"_id":"6fb52c4798e6186baf9871ce19000a8d","_rev":"1-8ccb83bd8362d56d396fb84e875dcae9","id":"bob","_attachments":{"foo.txt":{"content_type":"text/plain","revpos":1,"digest":"md5-iRNdzYnZ/dk8u44XAJXaAQ==","data":"holymoly"}}}}
],
"last_seq":1}
{Code}
In CouchDB 2.0, only the stub document is returned:
{Code}
~$ curl -X PUT http://127.0.0.1:15984/test
{"ok":true}
~$ curl -X POST http://127.0.0.1:15984/test -H 'Content-type:application/json'

This causes PouchDB's tests which passed with 1.6 to fail with 2.0
