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
1. Include the builtin-actors in the lotus source tree.
2. Embed the bundle on build instead of downloading at runtime.
3. Avoid reading the bundle whenever possible by including bundle
metadata (the bundle CID, the actor CIDs, etc.).
4. Remove everything related to dependency injection.
1. We're no longer downloading the bundle, so doing anything ahead
of time doesn't really help.
2. We register the manifests on init because, unfortunately, they're
global.
3. We explicitly load the current actors bundle in the genesis
state-tree method.
4. For testing, we just change the in-use bundle with a bit of a
hack. It's not great, but using dependency injection doesn't make
any sense either because, again, the manifest information is
global.
5. Remove the bundle.toml file. Bundles may be overridden by
specifying an override path in the parameters file, or an
environment variable.
fixes#8701
While over-estimation fees and miner tips are still paid, gas is no longer burnt
for direct, successful window PoSt messages.
Usually, gas is burnt to prevent an attacker from spamming the network and to
allow clients to "price" messages (using the base fee cap) based on how urgently
they need them to be processed. However:
1. Window PoSt is already a "proof of work".
2. Miners need to submit WindowedPoSts on-time so all window post messages are urgent.
3. Work is already under way to move window post verification off-chain (making
it effectively free). This change simply introduces the "free" part a bit earlier.
