Description

Context

I want to be able to trigger a refresh of my IPNS value. I tried lowering TTL & MaxCacheTTL (as suggested here) - but that will mean that the gateway has a ~40s delay for the first request after the cache entry was evicted.

So I thought: what if I regularily resovle the IPNS value without cache and thus refresh the cache?

❯ ipfs name resolve k51qzi5uqu5dmi4ub822smfsajlh7utzcupuihc76py1zbzafe71rbmzm9jml3
/ipfs/bafybeih6fphlvcqaq6qmgsg7fky3vxxnyomtd6cmtvhrdtpob4m3v7pqou # old value
❯ ipfs name resolve --nocache --dhtt 10s k51qzi5uqu5dmi4ub822smfsajlh7utzcupuihc76py1zbzafe71rbmzm9jml3
/ipfs/bafybeighh3capanjwiug2aos6267krmv4czp2tdjzjn7wpfqnpe4jqpa4y # new value
❯ ipfs name resolve k51qzi5uqu5dmi4ub822smfsajlh7utzcupuihc76py1zbzafe71rbmzm9jml3
/ipfs/bafybeih6fphlvcqaq6qmgsg7fky3vxxnyomtd6cmtvhrdtpob4m3v7pqou # old value

It turns out kubo does find the new value, but appears to completely bypass the cache - also not updating it. That is unfortunate :/

[gammazero]

This is a sensible request but we should not change the way that --nocache works. instead, there should be something like --cache-purge to do what you are asking for.

[tennox]

Thanks. To be clear - it should not purge the cache, but update it when the value changed (i.e. there should not be a time in which there is no cache entry, which would delay gateway responses)

[lidel]

Maybe -f / --force (or --force-update) then, to make it very clear what it does?
