Introduce nv21 skeleton for local testing:
- Use local go-state-types with actor_version_checklist changes: https://github.com/filecoin-project/go-state-types/blob/master/actors_version_checklist.md
- Imports mock v12-actors bundle
- Define upgrade heights
- Generate adapters
- Add upgrade schedule and migration
- Add actorstype to the NewActorRegistry in /chain/consensus/computestate.go
- Add upgrade field to api/types.go/ForkUpgradeParams
- Add upgrade to node/impl/full/state.go
- Add network version to chain/state/statetree.go
- make jen
- make docsgen-cli
Update to go-state-types v0.11.0-alpha-1
Introduce dummy v11 actor bundles
Make new actors adapters
Add upgrade to Upgrade Schedules
make jen
Update to go-state-types v0.11.0-alpha-2
- adds the following methods to all generated actor interfaces:
- Code() cid.Cid
- ActorKey() string
- ActorVersion() actorstypes.Version
- AllCodes() []cid.Cid
Method numbers never change anyways. At worst, we'll deprecate old methods and
have to explicitly import them from the correct actors version to use them.
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`.
This patch starts adding support for network upgrades.
* It adds an actors abstraction layer for loading abstract (cross-version) actors.
* It starts switching over to a shared deadline type.
* It adds an abstraction for ADTs (hamt/amt).
* It removes the callback-based API in the StateManager (difficult to abstract
across actor versions).
* It _does not_ actually add support for actors v2. We can do that in a followup
patch but that should be relatively easy.
This patch is heavily WIP and does not compile. Feel free to push changes
directly to this branch.
Notes:
* State tree access now needs a network version, because the HAMT type will change.
* I haven't figured out a nice way to abstract over changes to the _message_
types. However, many of them will be type aliased to actors v0 in actors v2 so
we can likely continue using the v0 versions (or use the v2 versions
everywhere). I've been renaming imports to `v0*` to make it clear that we're
importing types from a _specific_ actors version.
TODO:
* Consider merging incremental improvements? We'd have to get this compiling
again first but we could merge in the new abstractions, and slowly switch over.
* Finish migrating to the new abstractions.
* Remove all actor state types from the public API. See `miner.State.Info()` for
the planned approach here.
* Fix the tests. This is likely going to be a massive pain.
