wohali opened a new issue #506: replication to non-existent target db never updates _replicator doc with state URL: https://github.com/apache/couchdb/issues/506 # Steps to recreate 1. Create database `a` and put a few documents in it. Ensure a database `b` does not exist. 2. Create a `_replicator` document of the form: ```json { "_id": "foo_error_rep", "source": "http://127.0.0.1:15984/a";, "target": "http://127.0.0.1:15984/b"; } ``` 3. Wait a bit and check `_replicator/foo_error_rep`. No state has been added. I would have expected one of `crashing`, `running` or `pending`. # Logfile excerpt Note the throw of `db_not_found`. ``` [notice] 2017-05-03T21:49:42.495501Z [email protected] <0.309.0> 86f37313e7 127.0.0.1:15984 127.0.0.1 undefined GET /test_suite_db_ikklhwd%2F_replicator/foo_error_rep 200 ok 50 [notice] 2017-05-03T21:49:42.497481Z [email protected] <0.354.0> -------- starting new replication `b1137c827da5adb4376166374dcf79eb` at <0.1144.0> (`http://127.0.0.1:15984/test_suite_db_mxbhpygg/` -> `http://127.0.0.1:15984/nonexistent_test_db/`) [notice] 2017-05-03T21:49:42.497981Z [email protected] <0.355.0> -------- couch_replicator_scheduler: Job {"b1137c827da5adb4376166374dcf79eb",[]} started as <0.1144.0> [notice] 2017-05-03T21:49:42.547996Z [email protected] <0.309.0> 5ae0234b3c 127.0.0.1:15984 127.0.0.1 undefined GET /test_suite_db_ikklhwd%2F_replicator/foo_error_rep 200 ok 2 [notice] 2017-05-03T21:49:42.656934Z [email protected] <0.961.0> 7dd6682461 127.0.0.1:15984 127.0.0.1 undefined GET /test_suite_db_mxbhpygg/ 200 ok 147 [notice] 2017-05-03T21:49:42.657324Z [email protected] <0.309.0> 94c75a3e9a 127.0.0.1:15984 127.0.0.1 undefined GET /test_suite_db_ikklhwd%2F_replicator/foo_error_rep 200 ok 58 [notice] 2017-05-03T21:49:42.659778Z [email protected] <0.961.0> 286570172d 127.0.0.1:15984 127.0.0.1 undefined GET /nonexistent_test_db/ 404 ok 1 [error] 2017-05-03T21:49:42.660836Z [email protected] <0.1144.0> -------- throw:{db_not_found,<<"could not open http://127.0.0.1:15984/nonexistent_test_db/";>>}: Replication failed to start for args {rep,{"b1137c827da5adb4376166374dcf79eb",[]},{httpdb,"http://127.0.0.1:15984/test_suite_db_mxbhpygg/",nil,[{"Accept","application/json"},{"User-Agent","CouchDB-Replicator/2.1.0-5cad2a4"}],30000,[{socket_options,[{keepalive,true},{nodelay,false}]}],10,250,nil,20,nil,undefined},{httpdb,"http://127.0.0.1:15984/nonexistent_test_db/",nil,[{"Accept","application/json"},{"User-Agent","CouchDB-Replicator/2.1.0-5cad2a4"}],30000,[{socket_options,[{keepalive,true},{nodelay,false}]}],10,250,nil,20,nil,undefined},[{checkpoint_interval,30000},{connection_timeout,30000},{http_connections,20},{retries,10},{socket_options,[{keepalive,true},{nodelay,false}]},{use_checkpoints,true},{worker_batch_size,500},{worker_processes,4}],{user_ctx,null,[],undefined},db,nil,<<"foo_error_rep">>,<<"shards/00000000-1fffff ff/test_suite_db_ikklhwd/_replicator.1493848173">>,{1493,848182,496186}}: [{couch_replicator_api_wrap,db_open,3,[{file,"src/couch_replicator_api_wrap.erl"},{line,109}]},{couch_replicator_scheduler_job,init_state,1,[{file,"src/couch_replicator_scheduler_job.erl"},{line,568}]},{couch_replicator_scheduler_job,do_init,1,[{file,"src/couch_replicator_scheduler_job.erl"},{line,127}]},{couch_replicator_scheduler_job,handle_info,2,[{file,"src/couch_replicator_scheduler_job.erl"},{line,357}]},{gen_server,handle_msg,5,[{file,"gen_server.erl"},{line,599}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,237}]}] [notice] 2017-05-03T21:49:42.709448Z [email protected] <0.309.0> 5a9498eacf 127.0.0.1:15984 127.0.0.1 undefined GET /test_suite_db_ikklhwd%2F_replicator/foo_error_rep 200 ok 2 ``` /cc @nickva I think this is a new bug related to the scheduling replicator work. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
