Remove crate name from logs

[ansermino]

Issue summary

Forest's logs are seemingly bloated with forest_filecoin.

2024-08-19T02:35:36.945364Z  INFO forest_filecoin::chain::store::chain_store: ...
2024-08-19T02:35:36.945419Z  INFO forest_filecoin::chain_sync::tipset_syncer: ...
2024-08-19T02:36:18.359253Z  INFO forest_filecoin::blocks::tipset: ...

This should be omitted to improve readability.

@ansermino I wouldn't say this should be removed. It's an important part of the path. While in a happy path, forest_filecoin is indeed just a noise, in case of errors or different logging settings, more modules might pop up with logs originating from libraries upon which Forest depends.

That said, it might make sense to shorten it to just forest, if anything, just to save on log retention costs. What do you think?

[ansermino]

@LesnyRumcajs Whats the utility of these paths in the logs? What purpose (and who) do they serve?

Shortening to forest definitely makes sense. However, I'm still convinced it can be omitted entirely. If dependencies have full paths it should stil be trivial to infer the full path for forest modules

[LesnyRumcajs]

It helps with parsing post-factum the logs. Say, you'd like to get logs from the p2p layer of Forest (but not the nitty-gritty details from rust-libp2p) - you could do ... | grep forest | grep p2p. If we omit this, it would be ambiguous.

2024-08-19T14:14:09.354040Z DEBUG Swarm::poll: libp2p_gossipsub::behaviour: Completed message handling for message c75cb23c229e145b869ab5e485f3d7d0e02c48bfc7432ed862c43eddbbbd5982
2024-08-19T14:14:09.720972Z DEBUG forest_filecoin::libp2p::peer_manager: logging global success

You could do grep -v p2p_, but in general, I'd keep the module. It's also informative for developers to immediately see if a particular log message is coming from Forest or one of its dependencies.

[ansermino]

In your example it seems there would still be a clear distinction between the modules, it just requires the right module name(s) to be queried (eg. libp2p_gossipsub).

This also touches on a philosophical question—who are the logs for? Forest devs or users? It's presumably a bit of both, but it does seem sensible to optimize for the majority (users) in most cases. We might consider hiding the full path behind a config option, or adding more stack traces to error logs.

Replacing filecoin-forest with forest seems like a tangible improvement. Lets just do that for now, and revisit this as needed.

[LesnyRumcajs]

On the philosophical question - logs of INFO and above levels are for devs AND users, anything below - strictly for devs. In any case, I'd make drastic changes if there's a strict requirement from node providers (it may also include even further shortening the logs for data retention savings, e.g., DEBUG - D, INFO - I...).

I'm for shortening to forest, given that filecoin- doesn't bring any supplementary information.
