_update handler breaks after a conflict is resolved
---------------------------------------------------
Key: COUCHDB-1200
URL: https://issues.apache.org/jira/browse/COUCHDB-1200
Project: CouchDB
Issue Type: Bug
Components: Database Core, Replication
Affects Versions: 1.1
Reporter: Pete Vander Giessen
My update handlers break after I've introduced and resolved a conflict. Despite
the conflict being resolve, I get the following error when trying to run an
update handler on a once-conflicted document:
{"error":"conflict","reason":"Document update conflict."}
The following script reproduces the issue on 1.1.x. The issue does not appear
when run against a build of trunk:
#!/bin/bash
export HOST=http://localhost:5984
echo "Step 1a -- setup dbs"
curl -X DELETE $HOST/db0
curl -X DELETE $HOST/db1
curl -X PUT $HOST/db0
curl -X PUT $HOST/db1
echo "step 1b -- create an update handler "
curl -X PUT $HOST/db0/_design/foo -d '{"updates":{"bar":"function(doc, req) {
doc.foo=1; return [doc, \"ok\"];}"}}'
echo "step 2 -- create a doc"
curl -X PUT $HOST/db0/doc1 -d '{content}'
curl -X GET $HOST/db0/doc1
echo "step 3 -- replicate"
curl -X POST $HOST/_replicate -d '{"source":"db0","target":"db1"}' -H
"Content-Type:application/json"
echo "step 4 -- a new version of the doc on both dbs"
curl -X PUT $HOST/db0/doc1 -d
'{"_rev":"1-05a05c54cce81cc30df678afeab60f6c","content":"some content"}'
curl -X PUT $HOST/db1/doc1 -d
'{"_rev":"1-05a05c54cce81cc30df678afeab60f6c","content":"some different
content"}'
echo "step 5 -- create a conflict "
curl -X POST $HOST/_replicate -d '{"target":"db0","source":"db1"}' -H
"Content-Type:application/json"
echo "confirm conflict"
curl -X GET $HOST/db0/doc1?conflicts=true
echo "step 6 -- resolve the conflict"
curl -X DELETE $HOST/db0/doc1?rev=2-2efe11aab7e71ce9124a1039129512da
echo "step 7 -- check to make sure resolved"
curl "$HOST/db0/doc1?conflicts=true&deleted_conflicts=true"
echo "step 8 -- attempt to PUT to our update handler: this produces the error"
curl -X PUT
$HOST/db0/_design/foo/_update/bar/doc1?2-3b2f178dbc5e76cbd8df3ddca1963f4b -d
'{}'
echo "step 9 -- double-check that conflict was resolved"
curl "$HOST/db0/doc1?conflicts=true&deleted_conflicts=true"
echo "step 10 -- confirm that we can still do a normal PUT"
curl -X PUT $HOST/db0/doc1 -d
'{"_id":"doc1","_rev":"2-3b2f178dbc5e76cbd8df3ddca1963f4b","content":"some
content fnord"}'
