James Howe commented on COUCHDB-885: ------------------------------------ This issue is still present in 1.0.2, even though COUCHDB-902 is fixed. Specifically the following process creates a conflict: couch1 - add new document A in test_db replicate {source: test_db, target: http://couch2/testdb} couch1 - add attachment to A replicate {source: test_db, target: http://couch2/testdb} couch2/testdb/A?open_revs=all now shows a conflict > Attachments introduce conflicts after replication. > -------------------------------------------------- > > Key: COUCHDB-885 > URL: https://issues.apache.org/jira/browse/COUCHDB-885 > Project: CouchDB > Issue Type: Bug > Components: Database Core > Affects Versions: 1.0.1 > Environment: Mac OSX, Windows XP, Windows 7 > Reporter: Nikolai Teofilov > Fix For: 1.2 > > > Step to reproduce the bug: > 1. Make database "test" on a remote couchdb server that reside on a > different machine! > 2. Create new document: "http://remote-server:5984/test/doc" > 3. Create database "replica" on the local couchdb server. > 4. Trigger pull replication http://remote-server:5984/test -> > http://localhost:5984/replica > 5. Attach a file to the replicated document on the local couchdb server. > 6. Trigger push replication http://localhost:5984/replica -> > http://remote-server:5984/test > The document in the test database shows one conflict. If instead attachment > the document is updated with a new field after the replication no conflict. > The same sequence shows no conflicts on CouchDB 0.11. > ************ test.sh **************** > #!/usr/bin/env bash > LOCAL="http://localhost:5984" > REMOTE="http://koleto.couchone.com" > echo "=====================================================" > echo "This sequence create a conflict after the replication" > echo "=====================================================" > echo "Cleanup" > curl --silent -X DELETE $LOCAL/replica > curl --silent -X DELETE $REMOTE/test > echo "Create database:" $REMOTE/test > curl --silent -X PUT $REMOTE/test > echo "Create empty document:" > curl --silent -d '{}' -X PUT $REMOTE/test/doc > echo "Create local databse:" $LOCAL/replica > curl --silent -X PUT $LOCAL/replica > echo "Pull replication:" REMOTE/test "->" $LOCAL/replica > curl --silent -X POST -d > "{\"source\":\"$REMOTE/test\",\"target\":\"$LOCAL/replica\"}" -H > 'Content-Type: application/json' $LOCAL/_replicate > echo "Put an attachment to the document:" > echo "foobar!" | curl --silent --upload-file - -X PUT > "$LOCAL/replica/doc/foo.txt?rev=1-967a00dff5e02add41819138abb3284d" > echo "Push replication:" $LOCAL/replica "->" $REMOTE/test > curl --silent -X POST -d > "{\"source\":\"$LOCAL/replica\",\"target\":\"$REMOTE/test\"}" -H > 'Content-Type: application/json' $LOCAL/_replicate > echo '############## Get one conflic #####################' > curl --silent -X GET $REMOTE/test/doc?conflicts=true > echo "=====================================================" > echo "The same sequence with adding a field to the document" > echo "=====================================================" > echo "Cleanup" > curl --silent -X DELETE $LOCAL/replica > curl --silent -X DELETE $REMOTE/test > echo "Create database:" $REMOTE/test > curl --silent -X PUT $REMOTE/test > echo "Create empty document:" > curl --silent -d '{}' -X PUT $REMOTE/test/doc > echo "Create local databse:" $LOCAL/replica > curl --silent -X PUT $LOCAL/replica > echo "Pull replication:" REMOTE/test "->" $LOCAL/replica > curl --silent -X POST -d > "{\"source\":\"$REMOTE/test\",\"target\":\"$LOCAL/replica\"}" -H > 'Content-Type: application/json' $LOCAL/_replicate > echo "Adding a new field:" > curl --silent -d '{"foo":"bar" , "_rev" : > "1-967a00dff5e02add41819138abb3284d" }' -X PUT > $LOCAL/replica/doc?rev=1-967a00dff5e02add41819138abb3284d > echo "Push replication:" $LOCAL/replica "->" $REMOTE/test > curl --silent -X POST -d > "{\"source\":\"$LOCAL/replica\",\"target\":\"$REMOTE/test\"}" -H > 'Content-Type: application/json' $LOCAL/_replicate > echo '###### No conflicts after the replication ########' > curl --silent -X GET $REMOTE/test/doc?conflicts=true > -- This message is automatically generated by JIRA.
