This commit adds the icase name to the log filename, to make it simpler
to find problematic tests. Additionally after this commit we'll restart
Alice and Bob (the base harness nodes) before each icase to start with a
clean state.
It's been sometime since we introduced this new safety enhancing feature
bit. At this point, we're now moving to require it as it makes our SCB
recovery system more robust, and it's also an implicit feature bit for
for anchor commitments as they're defined now.
The getblockchaininfo call in bitcoind uses a commonly used lock,
csmain, in bitcoind. This made the endpoint unsuitable for a health
check, because some nodes were seeing waits up to 5 minutes (!). This
commit updates our health check function to use the uptime api, provided
our bitcoind version is > 0.15, when the api was added. We do not need
to switch our health check for btcd, because it has more granular
locking.
Add more fields to channel acceptor response so that users can have more
fine grained control over their incoming channels. With our chained
acceptor, it is possible that we get inconsistent responses from
multiple chained acceptors. We create a conjugate repsponse from all the
set fields in our various responses, but fail if we get different, non-
zero responses from our various acceptors. Separate merge functions are
used per type so that we avoid unexpected outcomes comparing interfaces
(panic on comparing types that aren't comparable), with casting used
where applicable to avoid code duplication.
This commit adds an optional error message to the channel acceptor's
reponse to allow operators to inform (or insult) unsuccessful channel
initiators as to the reason for their rejection.
This field is added in addition to the existing accept field to maintain
backwards compatibity. If we were to deprecate accept and interpret a
non-nil error as rejecting the channel, then received a response with
accept=false and a nil error, the server cannot tell whether this is a
legacy rejection or new mesage type acceptance (due to nil error),
so we keep both fields.
This commit moves and partially refactors the channel acceptor logic
added in c2a6c86e into the channel acceptor package. This allows us to
use the same logic in our unit tests as the rpcserver, rather than
needing to replicate it in unit tests.
Two changes are made to the existing implementation:
- Rather than having the Accept function run a closure, the closure
originally used in the rpcserver is moved directly into Accept
- The done channel used to signal client exit is moved into the acceptor
because the rpc server does not need knowledge of this detail (in
addition to other fields required for mocking the actual rpc).

This will prevent the subservers from writing macaroons to disk
when the stateless_init flag is set to true. It accomplishes
this by storing the StatelessInit value in the Macaroon Service.
Because we'll need to return the macaroon through the wallet unlocker
we cannot shut down its service before we have done so, otherwise
we'll end up in a deadlock. That's why we collect all shutdown
tasks and return them as a function that can be called after we've
initialized the macaroon service.
As a preparation for the next commit where we add proper wallet unlocker
shutdown handling, we move the calls that require cleanup down after the
creation of the wallet unlocker service itself.
To make sure no macaroons are created anywhere if the stateless
initialization was requested, we keep the requested initialization mode
in the memory of the macaroon service.
This commit adds the --stateless_init flag to all three wallet unlocker
operations. Once you initialize a wallet stateless, you need to set
this flag for every further wallet unlocker operation. Otherwise you
risk non-encrypted macaroon information to leak to the underlying
system.
