Multiple faces created for the same endpoint
When multiple "create" requests are issued back to back (before the first one is processed), NFD will process both requests and create duplicate Face entries.
Steps to reproduce:
- start NFD
run the following commmand:
(nfdc create tcp4://sirius.cs.memphis.edu &); nfdc create tcp4://sirius.cs.memphis.edu
Expected result: only one face tcp4://22.214.171.124:6363 created
Actual: two faces for tcp4://126.96.36.199:6363 are created
