We will be using `plugin_hook_call_next` as part of the loop to traverse all
plugins that registered the hook, so group initialization in the init function
and move per-plugin logic into `plugin_hook_call_next`
We are about to call multiple plugins, and we'll have to pass the payload into
each call. Sadly the serialized stream gets consumed during the call, so keep
the unserialized payload around.
Switch from having a single plugin to a list of plugins. If the hook is of
type single we will enforce that constraint on the number of registered
plugins when attempting to add.
The newly introduced type is used to determine what the call semantics of the
hook are. We have `single` corresponding to the old behavior, as well as
`chain` which allows multiple plugins to register for the hook, and they are
then called sequentially (if all plugins return `{"result": "continue"}`) or
exit the chain if the hook event was handled.
This is the last venue we need to add custom featurebits to, so we also unmark
the test as xfail.
Changelog-Added: plugin: Plugins can now signal support for experimental protocol extensions by registering featurebits for `node_announcement`s, the connection handshake, and for invoices. For now this is limited to non-dynamic plugins only
The `init_featurebits` are computed at startup, and then cached
indefinitely. They are then used whenever a new `init` handshake is performed.
We could add a new message to push updates to `connectd` whenever a plugin is
added or removed, but that's up for discussion.
we have 4 venues in which we can add features, 3 of which are unilaterally
controlled (`init`, `node_announcement`, and `invoices`) the
`channel_announcement` is co-signed by both parties, so we can't add
featurebits without additional coordination overhead.
Each location is encoded as a key-value pair in a dict called `featurebits` in
the manifest (omitted if no custom featurebits are set).
Break out a method for canceling a channel that will either
loop through contacting the peer to tell them of the error or
just directly cleans up if the peer is currently disconnected.
restrict fundchannel_cancel usage to only the opener side
Changelog-Changed: Only the opener of a fundchannel can cancel the channel open with fundchannel_cancel
Changelog-Fixed: Fixed factual errors in `lightning-listchannels.7` documentation.
`delay` is ***not*** the unilateral close delay for that channel-direction!
As a separated commit because it was pre-existent (changelog + xfail test).
This also fix a logical problem in lightningd/plugin_control: we were
assuming a plugin started with 'plugin start' but which did not comport
a 'dynamic' entry in its manifest to be dynamic, though it should have
been treated as static.
Changelog-fixed: plugins: Dynamic C plugins can now be managed when lightningd is up
This adds helpers to start and send a jsonrpc request using json_stream
in order to benefit from the helpers.
This then simplifies existing plugins RPC requests by using json_stream
helpers.
Since the probing binaries compiled by the configurator needs to run on
the host machine we provide a variable CONFIGURATOR_WRAPPER that can be
set to anything that you want to wrap the calls with.
One example is `qemu-aarch64-static`.
Didn't generally fixup inside comments and the bech32 code: reformatting that
is just anti-social.

Otherwise you can ask for a sub-millisatoshi amount, which is dumb and
violates the spec.
