Christian Decker e03acd9663 libplugin: Add features to plugin_main and getmanifest 2020-04-16 18:03:35 +09:30
Christian Decker a696c8417e fundchannel: Remove the now disabled deprecated `satoshi` param
While we removed the `satoshi` param in #3603 it appears that the
`fundchannel` plugin was still passing it to the `fundchannel_start`
call. This fixes up the help text. Notice that technically the help text
changes the param name, but since it was internally always called `amount`
this change doesn't break the API, the help was just wrong.

darosior b8262c3de2 fundechannel: don't pass deprecated 'satoshis' to fundchannel_start
Changelog-None
2020-04-06 11:54:37 +02:00
Rusty Russell 2f1502abf4 cleanup: make 'u8 *features' and 'struct feature_set *fset' more explicit.
It's almost always "their_features" and "our_features" respectively, so
make those names clear.

Rusty Russell e940d953bd fundchannel_start: We can't deprecate 'satoshi' here, since 'amount' wasn't sent
So we can't tell people they should use amount, until v0.8.2 is
released.  Another 6 months before we can deprecated the 'satoshi'
field here :(

Changelog-Deprecated: JSON: `fundchannel_start` `satoshi` field really deprecated now (use `amount`).

darosior 2bff80e3de libplugin: use json_stream helpers for RPC calls
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.

lisa neigut 689dd28ddd funding: enable push_msat
it's that time of year (merry xmas!)

enables the ability to push_msat on fundchannel

Changelog-Added: RPC: `fundchannel` and `fundchannel_start` can now accept an optional parameter, `push_msat`, which will gift that amount of satoshis to the peer at channel open.

trueptolemy aafa16786d JSON-API: `fundchannel` uses `amount` fieldname to replace `satoshi` 2019-10-09 16:51:42 -05:00
Christian Decker 7283efa5b5 elements: Add amount_asset to support more than just plain satoshis
Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.

Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.

Christian Decker 14247283b2 plugin: Tell the plugin which network we run on
The fundchannel plugin needs to know how to build a transaction, so we need to
tell it which chainparams to use. Also adds `chainparams` as a global, since
that seems to be the way to do things in plugins.

lisa neigut 548672ea0a fundchannel: populate max_funding from chainparams

lisa neigut 42ef64941a fundchannel: have address work with any network
`txprepare` verifies that you're sending to an address on the
right network, so this builds a placeholder address for the
right network.

lisa neigut 7d069239aa fundchannel: only cap to 'max' if keyword 'all' passed in
in order to preserve current behavior, we cap at max if specified 'all';
otherwise we fail since the amount requested is larger than the
channel max capacity

lisa neigut d9843c1957 fundchannel: handle 'all' for satoshi amount
Previously, we'd fail on 'all'. `fundchannel_start` needs an amount
in order to start a funding transaction.

The way that we approach this is to first call `txprepare` with a
placeholder address and the 'all' amount; this will return the maximum
amount available. We then clamp this to the max_funding (currently
hardcoded, in the future we'd want to consult our/the peer's features) and
then use the amount on the output in the prepared transaction as the
funding amount. We then pass this amount to fundchannel_start,
after we've started it successfully we cancel the held placeholder
transaction and prepare a second transaction for the exact amount,
using the funding address that fundchannel_start passed back.
