interop: supervisor_dependencySet API #684
Conversation
| - `chainIndex`: `ChainIndex`: the unique short identifier of this chain. | ||
| - `activationTime`: `uint64`: when the chain becomes part of the dependency set. | ||
| This is the minimum timestamp of the inclusion of an executing message. | ||
| - `historyMinTime`: `uint64`: the lower bound of data to store. |

| This is set to 0 when all data since genesis is executable. |

assume we will never want to store no data at all then

| The returned configuration may change with new chain upgrades. | ||

I would have instinctively though this should take a block number as parameter ..

Why are we exposing the config format here? We are exposing implementation details of the db (chain index + history min time) as well as the message expiry override time? What would the most useful API be from first principles?
I would guess its something like:
{
timestamp: { expiryWindow: x, chains: [chainid, chainid] },
timestamp2: { expiryWindow: y, chains: [chainid, chainid, chainid] }

This PR is old. The dependency set approach has changed a lot since. I will likely just replace it with an endpoint to get the list of chain IDs in the dependency set.

For readers: this PR is not accurate, the format changed last 2 weeks. Will need to update this after other higher priority work is out of the way. |
