Introduce v2 actors #3936

arajasek · 2020-09-21T06:56:55Z

Mostly opening this for illustrative purposes, but we could merge into #3781 fairly safely. Not gonna work correctly until all the TODO: ActorUpgrades are resolved, though.

Big TODOs:

Deal with payment channel parameter changes. This may require some retry logic, and will definitely require picking the right parameters across upgrades.
Fix "chain get". Currently, this command assumes exactly one version of specs-actors.
TESTING.

Some calls/operations will fail across the upgrade. Any funds associated with these operations (except the gas) will be returned to the sender.

If a user submits a message to create a multisig/paych actor, the message will not be accepted after the upgrade.
If a user submits a message to update a payment channel before the upgrade, it will not be accepted after the upgrade. HOWEVER, vouchers will remain valid and can be re-submitted after the upgrade.
If a multisig transaction to perform any operation listed here is proposed before the upgrade, it will fail if approved after the upgrade.

Open Concerns:

Performance. We currently run the state migration on gas estimation. This obviously has absolutely abysmal performance.
- We could cache migrations.
- We could just fail. Unfortunately, I'm concerned that lotus may not retry aggressively enough.
- We could "pretend" that we're still in the previous epoch, and estimate gas there (won't work for all messages).

I'm not sure what to do about the genesis code. It does some pretty hacky things to deal with the lack of power (adds fake power, adds sectors, then removes the fake power). I guess we can add a miner.SetEffectivePower function (to set the "this epoch" power), but that seems kind of sketch.

I'm not actually sure if we're doing this correctly anyways. We're setting TotalQualityAdjPower, TotalRawBytePower, and the "this epoch" variants. However, when computing things like pledge, we use the smoothed power, as far as I can tell.

Also, correctly handle multiple ADT versions.

Otherwise, we're going to end up with an import cycle between the adt and this version.

This will make it easier to load arbitrary actors. We can: * Type switch (sort of unsafe, may want marker methods?) * Use this with `vm.MutateActorState`.

We're probably going to want to change some of these design decisions down the road, but this is a good starting point. * We may want to use a more general test for "is actor valid at epoch". Maybe just a function? * I'd like to push some of the actor metadata down into the actor types themselves. Ideally, we'd be able to register actors with a simple `Register(validation, manyActors...)` call.

The actual actors version is v2, not v1. Using Version1 internally was really confusing.

+1 to just halting the chain, I think that's significantly better than allowing a (likely very broken) chain to continue and break state further.

(The answer might be different post-liftoff)

Generally looks good, flagged some nits that i can address

Submodules might need to be updated (or they're wrong in next)

Payment channel changes LGTM 👍

Performance. We currently run the state migration on gas estimation. This obviously has absolutely abysmal performance.

We could cache migrations.

We could just fail. Unfortunately, I'm concerned that lotus may not retry aggressively enough.

We could "pretend" that we're still in the previous epoch, and estimate gas there (won't work for all messages).

I feel like the last option is probably the most conservative here

Other than the gas estimation thing, this looks shippable
