Problem with changes feed and style=all_docs
Hi together,
I am using CouchDB Version 1.4.0 and the Changes Feed, but I have a
litte problem with the style option
(http://localhost:5984/db1/_changes?style=all_docs) in the query
request. The JSON output does not return all leaf revisions in the
changes array (including conflicts and deleted former conflictes) -
which is mentioned in the official CouchDB documentation.
Please see my example and the JSON output
curl -X GET http://localhost:5984/db1/_changes?style=all_docs
{"results":[
{"seq":3,"id":"81abd28f263b2046ddfc867247007275","changes":[{"rev":"3-1a796ab41eeb8bafd3d6025a4b31928f"}]}
],
"last_seq":3}
The JSON output is also the same as with style=main_only and I can also
query all revisions of the document _id
81abd28f263b2046ddfc867247007275.....
Is this a known bug?
Michael

Hi Alexander,
thank you very much for the curl example. Sorry maybe it was a mistake,
because I thought I would get all revisions of the document also
including the deleted+conflicts when I am querying the changes feed with
?style=all_docs.
But I looked into the erlang code - "couch_changes.erl" and tried it in
the erlang shell and seems to be correct :-)
-> couch_db:open_doc(Db2, DocInfo2, [deleted, conflicts])
Thanks,
Michael

Hi Michael,
Are you sure that there are any conflicted leafs for the
81abd28f263b2046ddfc867247007275 document?
[~]$ curl -X PUT http://localhost:5984/conflicts
{"ok":true}
[~]$ curl -X PUT http://localhost:5984/conflicts/doc \
-d '{"foo":"bar"}' \
-H "Content-Type: application/json"
{"ok":true,"id":"doc","rev":"1-4c6114c65e295552ab1019e2b046b10e"}
[~]$ curl -X PUT http://localhost:5984/conflicts/doc\?new_edits\=false \
-d '{"bar":"baz", "_rev": "1-078e832b49edb2a4b05b6d9ba627ff2f"}' \
-H "Content-Type: application/json"
{"ok":true,"id":"doc","rev":"1-078e832b49edb2a4b05b6d9ba627ff2f"}
[~]$ curl http://localhost:5984/conflicts/_changes\?style\=main_only
{"results":[
{"seq":2,"id":"doc","changes":[{"rev":"1-4c6114c65e295552ab1019e2b046b10e"}]}
],
"last_seq":2}
[~]$ curl http://localhost:5984/conflicts/_changes\?style\=all_docs
{"results":[
{"seq":2,"id":"doc","changes":[{"rev":"1-4c6114c65e295552ab1019e2b046b10e"},{"rev":"1-078e832b49edb2a4b05b6d9ba627ff2f"}]}
],
"last_seq":2}
You may query document with meta=true query parameter to verify that
conflicts are exists for this document:
[~]$ curl http://localhost:5984/conflicts/doc\?meta\=true
{"_id":"doc","_rev":"1-4c6114c65e295552ab1019e2b046b10e","foo":"bar","_revs_info":[{"rev":"1-4c6114c65e295552ab1019e2b046b10e","status":"available"}],"_conflicts":["1-078e832b49edb2a4b05b6d9ba627ff2f"]}
