This commit updates outdated dependencies and hangs all
bitcoin-related dependencies off of the `bitcoin` crate, using its
re-exports. This means that as long as the bitcoin crate matches, all
of its dependents will also match.
Changelog-None
We had a bit of a chicken-and-egg problem, where we instantiated the
`state` to be managed by the `Plugin` during the very first step when
creating the `Builder`, but then the state might depend on the
configuration we only get later. This would force developers to add
placeholders in the form of `Option` into the state, when really
they'd never be none after configuring.
This defers the binding until after we get the configuration and
cleans up the semantics:
- `Builder`: declare options, hooks, etc
- `ConfiguredPlugin`: we have exchanged the handshake with
`lightningd`, now we can construct the `state` accordingly
- `Plugin`: Running instance of the plugin
Changelog-Changed: cln-plugin: Moved the state binding to the plugin until after the configuration step
This is usually a signal that lightningd is shutting down, so notify
any instance that is waiting on `plugin.join()`.
Changelog-Fixed: cln-plugin: Fixed an issue where plugins would hang indefinitely despite `lightningd` closing the connection
We now have ternary outcomes for `Builder.configure()` and
`Builder.start()`:
- Ok(Some(p)) means we were configured correctly, and can continue
with our work normally
- Ok(None) means that `lightningd` was invoked with `--help`, we
weren't configured (which is not an error since the `lightningd` just
implicitly told us to shut down) and user code should clean up and
exit as well
- Err(e) something went wrong, user code may report an error and exit.
