## RPC/REST Server
|
|
|
|
|
|
|
|
|
|
- A `POST` URL mapping [was added to the REST version of the `QueryRoutes` call
|
|
|
|
|
(`POST /v1/graph/routes`)](https://github.com/lightningnetwork/lnd/pull/6926)
|
|
|
|
|
to make it possible to specify `route_hints` over REST.

lnwallet/chancloser: properly compute initial fee of cop close txn
In this commit, we modify the way we compute the starting ideal fee for
the co-op close transaction. Before thsi commit, channel.CalcFee was
used, which'll compute the fee based on the commitment transaction
itself, rathern than the co-op close transaction. As the co-op close
transaction is potentailly bigger (two P2TR outputs) than the commitment
transaction, this can cause us to under estimate the fee, which can
result in the fee rate being too low to propagate.
To remedy this, we now compute a fee estimate from scratch, based on the
delivery fees of the two parties.
We also add a bug fix in the chancloser unit tests that wasn't caught
due to loop variable shadowing.
The wallet import itest has been updated as well, since we'll now pay
600 extra saothis to close the channel, since we're accounting for the
added weight of the P2TR outputs.
Fixes #6953
