Is Calibnet ready to go? Could you rebase on main?

No it's not. There are still some sync issues.

Hey @ec2 helping @connormullett with this sync issue and would like to know if you have some idea why this is failing.

Basically everything looks good during the block validation (height 636,822) after importing the snapshot except one call that internally failed.

The offending callstack goes like this:

forest/blockchain/chain_sync/src/tipset_syncer.rs

Line 1366 in b202340

let hp = v_state_manager.eligible_to_mine(

forest/blockchain/state_manager/src/lib.rs

Line 657 in b202340

let hmp = self.miner_has_min_power(address, lookback_tipset)?;

forest/blockchain/state_manager/src/lib.rs

Line 1263 in b202340

.get_actor(actor::power::ADDRESS, ts.parent_state())?

forest/blockchain/state_manager/src/lib.rs

Line 138 in b202340

let state = StateTree::new_from_root(self.blockstore(), state_cid)?;

forest/vm/state_tree/src/lib.rs

Line 216 in b202340

let hamt = Map::load(&actors, store, version.into())?;

(Fallbacking to v0 state tree since retrieval failed)

forest/vm/actor_interface/src/adt/map.rs

Line 39 in b202340

ActorVersion::V0 => Ok(Map::V0(actorv0::make_map_with_root(cid, store)?)),

...

forest/ipld/hamt/src/hamt.rs

Line 96 in b202340

None => Err(Error::CidNotFound(cid.to_string())),

To sum up it seems to me that reading using the Cid bafy2bzacec4xpti63qilepxw4ofgbt7pdduumnvufaom53sfrkz5xdcslfxdk from the blockstore just returns a None and bubbles up to an error, later resulting in the log warning:

2022-02-15T11:38:30.664Z WARN chain_sync::tipset_syncer > Validating block [CID = bafy2bzacecnamj6hoxdsbdlkxs6fmug4nyndug2rubetymli6dkyf755gqeqg] in EPOCH = 636822 failed: Validation error: StateManager error: Cid (bafy2bzacec4xpti63qilepxw4ofgbt7pdduumnvufaom53sfrkz5xdcslfxdk) did not match any in database

Any ideas where this could come from or on how to continue debugging this? Thanks :)

linter fails on #1438

[connormullett]

Everything is g2g now. Should not sync past nv15 but doesn't panic

[LesnyRumcajs]

Should this be backported to ref-fvm? If I understand correctly, they have the same issue on their side so calibnet can't work with any implementation using ref-fvm, right? https://github.com/filecoin-project/ref-fvm/blob/lemmih/forest/ipld/hamt/src/node.rs#L396

[connormullett]

Good question, I'm going to say yes. I'll open a PR on their side with the same fix and see what they say
