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
- FSM handles the actual cc upgrade process including error states
- PoSting (winning and window) works over upgraded and upgrading sectors
- Integration test and changes to itest framework to reduce flakes
- Update CLI to handle new upgrade
- Update dependencies
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.
