Invalid stale timer for content store #45

Closed zjkmxy closed 1 year ago

This issue was reported by @haowaiwai. The CS serves obsoleted data to MustBeFresh Interest.

Step to reproduce the result:

Start YaNFD
Run echo 111 | ndnpoke -f 500 -w 10000 /ndn/igw11
Run ndnpeek -p -f -w 10000 /ndn/igw11
The consumer received 111 and the producer quited.
After 1 sec, run ndnpeek -p -f -w 10000 /ndn/igw11 again
The ndnpeek consumer may return obsoleted data.

The reason is that current PitCSTree implementation has bugs so that it fails to set the current stale timer.
