This commit moves all localized instances of mock implementations of
the Signer interface to the lntest/mock package. This allows us to
remove a lot of code and have it housed under a single interface in
many cases.
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.
To make sure we can use the abandonchannel RPC for getting rid of
externally funded channels who's funding transaction was never
published, we allow the RPC to be used on non-dev builds for externally
funded and pending channels only.
Externally funded channels are expected by the user and explicitly
registered through the use of a funding shim and should therefore not
count towards the max pending channel count which is primarily there to
mitigate DoS attacks.
Currenlty the maxHtlcs value is recomputed after receiving
accept_channel. This works when the derivation is deterministic, howver
we now allow the user to manually override this value from open_channel.
As such, we must retain the chosen value in memory throughout the
funding process, otherwise the initiator would revert to the
deterministic derivation and the two endpoints will disagree on the
correct max-htlcs value in their view of the other's policy.
This commit adds the same CORS functionality that's currently in the main gRPC proxy to the WalletUnlocker proxy. This ensures the CORS configuration is carried through all API endpoints
The PR #4421 updated the cert package. To make lnd usable as dependency
in other projects after the PR was merged, we need to tag and update the
cert package.
Add a new health check package which will periodically poll health
check functions and shutdown if we do not succeed after our set number
of attempts. The first check that we add is one for our chain backend,
to ensure that we are connected to a bitcoin node.
This commit adds a shutdown logger which will send a request for
shutdown on critical errors. It uses the signal package to request safe
shutdown of the daemon. Since we init our logs in config validation,
we add a started channel to the signal package to prevent the case where
we have a critical log after the ShutdownLogger has started but before
the daemon has started listening for intercepts. In this case, we just
ignore the shutdown request.
The old key expires in a month or so. We recently updated the key to use
a newer expiry date. This commit updates the link to point to the
updated gist.
