Previously we'd skip returning immature inputs to stay backwards
compatible. This has the downside as the node operator cannot take
actions on this input, like some customized batching strategy via
`bumpfee` RPC.
After this change, it means when calling `bumpfee` RPC, it will now
update the params for the immature input instead of returning an error
saying `output does not belong to wallet`.
We also add a `MaturityHeight` field so the user knows when this input
will be swept.
For legacy payments, the hash field will be nil, and we need to use the
payment identifier instead. We have multiple ways to fix this:
A trivial solution is we can simply call `sharder.GetHash` in
`collectResult`, and pass this hash to `attempt.Circuit()`, which ends
up multiple methods taking the hash. This is bad as it's confusing why
the methods of `HTLCAttempt` need to take another hash value, while
itself already has the info via `HTLCAttempt.Hash`. We don't want an
exceptional case to influence our main flow.
We can then patch the field `HTLCAttempt.Hash`, and set it to the
payment hash if it's nil, which can be done in `collectResult`. This is
also less optimal as it means every htlc attempts, either legacy or not,
now need to bear this context.
The best way to do this is to patch the field in
`reloadInflightAttempts`. As we are sure any new payments made won't be
legacy, and the only source of legacy payments comes from reloading
existing payments.
We now return the next retry fee rate in `TxFailed` event in
`TxPublisher`. When handling the event, `UtxoSweeper` will update the
inputs to make sure the starting fee rate is set before attempting the
next sweep.
We now always create the sweeping tx even though the budget cannot be
covered so we don't miss the deadline. Note that the fee bump will fail
once the provided wallet input cannot cover the increase fees, which is
fine as these inputs will be marked as failed and be retried again in
the next block. When that happens, if there are new wallet UTXOs, a new
batch will be created to perform the fee bump.
This commit makes sure when processing resolutions, e.g, settling
invoices, when the link is already broken, the process would exit with
an error. This fixes the issue we found in the itest, where an
unexpected empty remote pending commitment was created although the
remote peer is already offline.
In this commit, we add a new field `LockedIn` on HTLCs so it can be used
to decide whether an HTLC found on the local commitment has been
committed on the remote commitment.
Previously we'd restart Alice and then restart Bob, which means once
Alice is shut down and started again before we shut down Bob, Bob will
attempt to connect Alice since the connection is permanent, which could
put the node in a weird state. We now make sure both nodes are shut down
first, then bring them back online to avoid the above case. We may,
however, create another test in the future to check the above case if needed.
The `codes.Unimplemented` is only returned when the RPCs are not built.
When the wallet is in an unexpected state, `codes.Unknown` is returned
instead, so we need to catch it properly to make sure we return the
right error msg.
Previously, we would set the state of the syncer after sending the msg,
which has the following flow,
1. In state `queryNewChannels`, we send the msg `QueryShortChanIDs`.
2. Once the msg is sent, we change to state `waitingQueryChanReply`.
But there's no guarantee the remote won't reply back inbetween the two
step. When that happens, our syncer would still be in state
`queryNewChannels`, causing the following error,
```
[ERR] DISC gossiper.go:873: Process query msg from peer [Alice] got unexpected msg *lnwire.ReplyShortChanIDsEnd received in state queryNewChannels
```
To fix it, we now make sure the state is updated before sending the msg.
In this commit we document an unexpected behavior found when connecting
a bitcoind node to a btcd node. We mitigate this in our test by
reconnecting the nodes when the connection is broken. We also limit the
connection made from `bitcoind` to be v1 only.
We change how the `bitcoind` node connects to the miner by creating a
temp RPC client and use it to connect to the miner. In addition we also
assert the connection is made.
