wrong return of traces in bulk mode

[Italo Valcy S Brito]

Hi,

When running sdntrace-cp with more than one trace in bulk mode, the return seems to be incorrect. If I request 4 traces - three from the same switch and another one from a different switch - only two results are returned (from two different switches).

How to reproduce:

1. Using Kytos docker image amlight/kytos:latest and Mininet with linear topology (10 switches) mn --topo linear,10 --controller=remote,ip=127.0.0.1
2. Create three EVCs:

curl -H 'Content-type: application/json' -X POST http://127.0.0.1:8181/api/kytos/mef_eline/v2/evc -d '{"name": "my evc1", "dynamic_backup_path": true, "enabled": true, "uni_z": {"tag": {"value": 100, "tag_type": 1}, "interface_id": "00:00:00:00:00:00:00:0a:1"}, "uni_a": {"tag": {"value": 100, "tag_type": 1}, "interface_id": "00:00:00:00:00:00:00:01:1"}}'

curl -H 'Content-type: application/json' -X POST http://127.0.0.1:8181/api/kytos/mef_eline/v2/evc -d '{"name": "my evc1", "dynamic_backup_path": true, "enabled": true, "uni_z": {"tag": {"value": 101, "tag_type": 1}, "interface_id": "00:00:00:00:00:00:00:0a:1"}, "uni_a": {"tag": {"value": 101, "tag_type": 1}, "interface_id": "00:00:00:00:00:00:00:01:1"}}'

curl -H 'Content-type: application/json' -X POST http://127.0.0.1:8181/api/kytos/mef_eline/v2/evc -d '{"name": "my evc1", "dynamic_backup_path": true, "enabled": true, "uni_z": {"tag": {"value": 102, "tag_type": 1}, "interface_id": "00:00:00:00:00:00:00:0a:1"}, "uni_a": {"tag": {"value": 102, "tag_type": 1}, "interface_id": "00:00:00:00:00:00:00:01:1"}}'

3. Send the trace requests:

curl -v -X PUT -H 'Content-type: application/json' http://127.0.0.1:8181/api/amlight/sdntrace_cp/traces -d '[{"trace": {"switch": {"dpid": "00:00:00:00:00:00:00:01", "in_port": 1}, "eth": {"dl_vlan": 100}}}, {"trace": {"switch": {"dpid": "00:00:00:00:00:00:00:01", "in_port": 1}, "eth": {"dl_vlan": 101}}}, {"trace": {"switch": {"dpid": "00:00:00:00:00:00:00:01", "in_port": 1}, "eth": {"dl_vlan": 102}}}, {"trace": {"switch": {"dpid": "00:00:00:00:00:00:00:0a", "in_port": 1}, "eth": {"dl_vlan": 100}}}]'

Expected result: the sdntrace-cp should return 4 traces and their correspondent result

Actual result: only two results are returned:

root@b8c4cf3e46c6:/kytos-end-to-end-tests# curl -v -X PUT -H 'Content-type: application/json' http://127.0.0.1:8181/api/amlight/sdntrace_cp/traces -d '[{"trace": {"switch": {"dpid": "00:00:00:00:00:00:00:01", "in_port": 1}, "eth": {"dl_vlan": 100}}}, {"trace": {"switch": {"dpid": "00:00:00:00:00:00:00:01", "in_port": 1}, "eth": {"dl_vlan": 101}}}, {"trace": {"switch": {"dpid": "00:00:00:00:00:00:00:01", "in_port": 1}, "eth": {"dl_vlan": 102}}}, {"trace": {"switch": {"dpid": "00:00:00:00:00:00:00:0a", "in_port": 1}, "eth": {"dl_vlan": 100}}}]'
