We add an additional test case to the on-chain fund recovery test that
tries restoring the same wallet from the extended master root key
instead of the seed.
In addition to creating a new wallet from an aezeed, we allow specifying
an exteded master root key as the main wallet key directly.
Because an exteded key (xprv) doesn't contain any information about the
creation time of the wallet, we must assume a birthday to start scanning
the chain from (if the user doesn't provide an explicit value). Since
lnd only uses SegWit addresses, it makes sense to
choose the date that corresponds to the first mainnet block that
contained SegWit transactions.
Restoring a wallet from an extended master root key will result in a
significantly longer initial wallet rescan time if the default value is
used.
This commit fixes the issue where a wrong context being inherited to
create a timeout context. When a parent context timed out, all its
children contexts also timed out, even the children contexts had a
larger timeout value. This means it only makes sense to inherite from a
parent when its children have smaller timeout value. Given the setup of
the itest, all the timeout contexts need to be created from a context
background(hence no timeout on the parent) unless there's an explicit
timeout bound we want to set.
In this commit, we put the context initialization inside
openChannelAndAssert, thus saving us a few lines and making sure the
context is always properly handled.
This adds support for notifying systemd about the state of LND. It
notifies systemd just before waiting for wallet password or, if
`wallet-password-file` was specified, right after unlocking the wallet.
This means that "ready" represents RPC being available for intended use.
It's intentional, so that client services can use `After=` in `systemd`
configuration to avoid misleading error messages about missing files or
refused connections.
Part of #4470
In lnd, log messages about channels are generally logged with a
reference to their channel point rather than the short channel id.
Channel point is reorg-resistant and also easier to look up in for
example a block explorer.
In the link however, all log messages are accompanied by short channel
id. This makes it difficult to grep a log for all channel activity. The
PEER message for example which are often crucial to analyse, are logged
with channel points.
This commit modifies the link logging to also use channel points.
