Bug #1574
WriteHandle doesn't send interest for single insert
Description
When running ndnputfile with -s option, no Interests arrive and app stops with error that insert command check failed with 404.
NFD, ndnputfile and repo are all run on the same machine.
ndnputfile -s is used to put data into repo. The command line may like: ndnputfile -s /example/repo/1 /example/data/1/testfile testfile
On the ndnputfile side, ndnputfile will first express command and then setInterestFilter of /example/data/1/testfile.
On the repo side, repo will first response the command and then send interest of /example/data/1/testfile
The NFD log shows that, nfd first receives interest of /example/data/1/testfile and then add nexthop of /example/data/1/testfile.
If some delay of sending interest is put, the ndnputfile works well.
So I think that the nfd cannot control these things in right order and the client cannot get information from nfd to arrange this sequence.

ndnputfile should ensure that prefix registration is completed before repo can start retrieving the Data.
As I can see in repo-ng commit 91fb4f2e5067d2fd6a591d885353a449bc65b399, ndnputfile sends the insert command after prefix registration is successful.
At this point, FIB entry should be installed in NFD already.
If it's not, it's likely a problem in either NFD or RIB daemon.

Is is necessary to add interest retransmission for single insertion to resolve this bug? Besides, interest retransmission is a necessary feature for repo.

We need to find the root cause of why FIB add-nexthop arrives after repo-ng sends the data-retrieving Interest.

Single insertion works after updating new ndn-cxx and nfd... I don't know why.

Can you nail down the specific version of NFD and ndn-cxx which has the problem?

Long time has passed. I have forgotten the cause of this problem... But, anyway, it is resolved.
