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
This is a nicety for development, so that we always load a development bundle to avoid having
to give them distinct names etc. Just call you release "dev" or "dev.xxx..." and put the bundle
in `.lotus/builtin-actors/v8/dev/builting-actors-${network}.{car,sha256sum}` and it will be
unconditionally loaded.
Index provider integration uses a gossipsub topic to announce changes to
the advertised content. The topic name was fixed to the default topic
which is `/indexer/ingest/mainnet`.
In the case of lotus, the gossipsub validators enforce a list of topics
the instance is permitted to join by setting subscription filter option
when `PubSub` instance is constructed via DI.
Having the fixed topic name meant that any SP starting up a node on a
network other than `mainnet` would have to override the default config
to avoid the node crashing when index provider is enabled.
Instead of a fixed default, the changes here infer the allowed indexer
topic name from network name automatically if the topic configuration is
left empty.
