With this change we allow adding hop hints when adding an invoice, even
if its amount is zero.
A couple of new unit test case have been added, and the
`testInvoiceRoutingHints` itest was expanded to account for this
scenario.
In this commit, we introduce two mining methods, `MineBlocks` and
`MineBlocksAndAssertNumTxes`, to `HarnessTest`. These methods are
different from the miner's methods as they would 1) mine the blocks
slowly and 2) assert all active nodes have synced. The miner's methods
are kept for future tests such as mining blocks really fast and see the
behavior of `lnd`.
This commit breaks the large `testChannelBackupRestore` into smaller
tests to take advantage of our parallel testing framework. A smaller
test also makes the debugging easier, hence better code health.
This commit breaks the large `testMultiHopHtlcClaims` into independent
test cases to take the advantage of parallel testing. The old setup will
put the stress of creating and syncing new blocks into a single core,
which causes a much longer test time and sometimes times out.
This commit sends the returned value of pred() inside a goroutine such
that when a predicate function never returns during the first run, the
wait package can timeout properly.
This commit adds a new flag `temptest` so we can run new and old tests
separately. This flag will be removed once the migration from old tests
to new tests is finished.
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
