Bind drand and bootstrap peers config so that `PubSub` instantiated by
`ConfigCommon` has all the dependencies it needs when `PubSub` instance
is needed in markets. In ths case, the instance is needed by the index
provider engine to announce new indexing advertisements.
The markets process instantiates its own `PubSub` instance with all
validators, peer scoring, etc. set up. Use that instane to join the
indexing topic, otherwise the default topic instantiated by
index-provider internally (via go-legs) has no validators.
- add opt-in env var to control instantation, until we are comfortable with testing to enble by default.
- adjust default limits if the connection manager high mark is higher than the default inbound conn limit.
Integrate the latest `index-provider` and reflect the changes to engine
configuration. Note that this commit disables announcements of indices
on the network by default as requested for initial merge to master.
Introduce dedicated index provider configuration parameters with
documentation and defaults that match the defaults in index-provider.
Re-generate code as needed.
- Add comment to clarify the reason for loop in testkit
- Trim common prefix in state printed in CLI commands for better
readability
- Upgrade to a tagged release of `go-fil-markets` that includes indexing
work; see: https://github.com/filecoin-project/go-fil-markets/pull/673
- Fix typo in CLI usage.
- Add comments to note that it is safe to use fx `OnStart` context when
starting the provider engine.
- Fix string concatenation in error message formatting.
Now that host is shared having separate config for listen and announce
addresses along with graphsync limit makes no sense since all of that is
shared with the markets host and datatransfer manager.
Remove the bespoke instantiation of libp2p host and datatransfer manager
for index provider and reuse the existing instances used by markets.
The rationale for reuse is the following:
1. Separation of host introduces a discovery problem, where without
gossipsub the index provider endpoint will not be discoverable.
Using the same host as markets would mean the chain can be used to
discover addresses, putting less empassis on criticality of
gossipsub considering its set-up cost and lack of message delivery
guarantees.
2. Only a single instance of graphsync/datatransfer can be instantiated
per libp2p host; therefore, if the host is shared, so should
datatransfer manager.
3. it is not clear if the assumptions under which separation was
decided still hold.
