Description

Add a configuration option for ContentStore policy.

This is non-runtime settings (i.e., cannot be switched without restarting NFD).

The setting should be

...
tables
{
  # CS policy. Possible values are "priority_fifo" (default), "lru"
  cs_policy "lru"

  ...
}
...

NFD Developer Guide should be updated as part of this issue.

  • Subject changed from Allow configuring non-default CS policy in nfd.conf to Allow configuring CS policy in nfd.conf
  • Description updated (diff)
  • Estimated time set to 3.00 h

"fifo" is inaccurate. It should be "priority_fifo" because unsolicited and stale Data are evicted first.

Agree. The reason I used "fifo", because it is currently called this way in POLICY_NAME constant.

https://gerrit.named-data.net/3348 introduces a cs::Policy registration. Implementation is adapted from UnsolicitedDataPolicy registry.
This is manually tested by modifying makeDefaultPolicy function and observing Cs::setPolicyImpl logging.

we need at least another method to get names of available policies (for diagnostic message)

This should be applicable to CS policies, unsolicited Data policies, and strategies.
However, I wonder what's the use case?
For CS policies and unsolicited Data policies, there are only a small number of them, no runtime changes are allowed, and the full list is in nfd.conf sample.

NFD devguide is updated in nfd-docs:commit:e9b3753d50e4d6b35d8c7d72f72f1cb3824d4f1f and nfd-docs:commit:613fd0392226f11a7126e45780276a99c3e67710 to describe the tables.cs_policy config key. I also rewrote text for cs::Policy API intended to clear up some confusions on ndnSIM mailing list, but I did not change the description of specific policies.
