Now that we have all functions that we need to complete the whole
PSBT channel funding flow, we change the itest to use Dave's wallet
to fund the channel from Carol to Dave through a PSBT.
We fix all linter issues except for the 'lostcontext' and 'unparam' ones
as those are too numerous and would increase the diff even more.
Therefore we silence them in the itest directory for now.
Because the linter is still not build tag aware, we also have to silence
the unused and deadcode sub linters to not get false positives.
In this commit, we modify our build tag set up to allow the main test
files to be buildable w/o the current rpctest tag. We do this so that
those of us that use extensions which will compile live files like
vim-go can once again fix compile errors as we go in our editors.
In order to do this, we now make an external `testsCases` variable, and
have two variants: one that's empty (no build tag), and one that's fully
populated with all our tests (build tag active). As a result, the main
file will now always build regardless of if the build tag is active or
not, but we'll only actually execute tests if the `testCases` variable
has been populated.
As sample run w/ the tag off:
```
=== RUN TestLightningNetworkDaemon
--- PASS: TestLightningNetworkDaemon (0.00s)
PASS
ok github.com/lightningnetwork/lnd/lntest/itest 0.051s
```
For unconfirmed commit tx anchors, supply the sweeper with cpfp info and
a confirmation target fee estimate.
The sweeper will try to pay for the parent commit tx as long as the
current fee estimate exceeds the pre-signed commit tx fee rate.
As we already create two channels in our PSBT funding flow itest we can
easily just submit the final transaction for the second channel in the
raw wire format to test this new functionality.
- let users specify their MAXIMUM WUMBO with new config option which sets the maximum channel size lnd will accept
- current implementation is a simple check by the fundingManager rather than anything to do with the ChannelAcceptor
- Add test cases which verify that maximum channel limit is respected for wumbo/non-wumbo channels
- use --maxchansize 0 value to distinguish set/unset config. If user sets max value to 0 it will not do anything as 0 is currently used to indicate to the funding manager that the limit should not be enforced. This seems justifiable since --maxchansize=0 doesn't seem to make sense at first glance.
- add integration test case to ensure that config parsing and valiation is proper. I simplified the funding managers check electing to rely on config.go to correctly parse and set up either i) non wumbo default limit of 0.16 BTC OR ii) wumbo default soft limit of 10 BTC

Previously the chainbackend connected to the miner using a permanent
connection, which would retry the connection when it’s disconnected.
It would leave multiple connections between the chainbackend and the
miner, causing difficulties in debugging. Currently, there are two
occasions when disconnection happens. One happens when running the open
channel reorg test, the miner is connected/disconnected multiple times
on purpose. The other happens when the chainbackend receives a
MSG_WITNESS_TX type from the miner, which would be considered as an
invalid type and disconnects the miner. With the latter one being fixed
in btcd, the chainbackend will still be disconnected from the miner if
it reaches the ban score by requesting too many notfound messages in a
short time which is why the `--nobanning` flag is added.
To fix the compiler of some IDEs complaining about types and functions
it cannot find, we rename all files that contain tests back to lnd_xxx_test.go to make
sure they are compiled correctly.
We change the external funding test to now test two more things: First
that we can open multiple externally funded channels without needing to
lift the default --maxpendingchannels setting. Then we test that we can
use the safer pending_funding_shim_only flag of the AbandonChannel RPC
to get rid of the never confirming external channels.
As a preparation to test accepting multiple externally funded channels
at the same time, we extract the deriveFundingShim function from the
external funding integration test.
