SettleHodlInvoice and CancelInvoice both notifyClients after
notifyHodlSubscribers. This commit changes UpdateInvoice to follow the
same pattern so that we are consistent.
This was initially done as there were a few assertions throughout the
codebase requiring a channel's policy to be known. Now that these have
been addressed, we no longer need to store restored channels in the
graph, as their policies where incomplete anyway.
Modifies syncer.replyChanRangeQuery method to use the LastBlockHeight
method on the query. LastBlockHeight safely calculates the ending
block height and prevents an overflow of start_block + num_blocks.
Prior to this change, query messages that had a start_block +
num_blocks that overflows uint32_max would return zero results in the
reply message.
Tests are added to fix the bug and ensure proper start and end values
are supplied to the channel graph filter.
Introduces a new chancloser package which exposes a ChanCloser
struct that handles the cooperative channel closure negotiation
and is meant to replace chancloser.go in the lnd package. Updates
all references to chancloser.go to instead use chancloser package.
The current implementation of LeaseOutput already checked whether the
output had already been leased by the persisted implementation, but not
the in-memory one used by lnd internally. Without this check, we could
potentially end up with a double spend error if lnd acquired the UTXO
internally before the LeaseOutput call.
This addresses a panic when a notification is canceled after its been
detected as included in a block and before its confirmation notification
is dispatched.
Use the new paginatior strcut for payments. Add some tests which will
specifically test cases on and around the missing index we force in our
test to ensure that we properly handle this case. We also add a sanity
check in the test that checks that we can query when we have no
payments.
With our new index of sequence number to index, it is possible for
more than one sequence number to point to the same hash because legacy
lnd allowed duplicate payments under the same hash. We now store these
payments in a nested bucket within the payments database. To allow
lookup of the correct payment from an index, we require matching of the
payment hash and sequence number.
We now use the same method of pagination for invoices and payments.
Rather than duplicate logic across calls, we add a pagnator struct
which can have query specific logic plugged into it. This commit also
addresses an existing issue where a reverse query for invoices with an
offset larger than our last offset would not return any invoices. We
update this behaviour to act more like c.Seek and just start from the
last entry. This behaviour change is covered by a unit test that
previously checked for the lack of invoices.
In our current invoice pagination logic, we would not return any
invoices if our offset index was more than 1 off our last index and we
were paginating backwards. This commit adds a test case for this
behaviour before fixing it in the next commit.
Add an entry to a payments index bucket which maps sequence number
to payment hash when we initiate payments. This allows for more
efficient paginated queries. We create the top level bucket in its
own migration so that we do not need to create it on the fly.
When we retry payments and provide them with a new sequence number, we
delete the index for their existing payment so that we do not have an
index that points to a non-existent payment.
If we delete a payment, we also delete its index entry. This prevents
us from looking up entries from indexes to payments that do not exist.
Update our current tests to include lookup of duplicate payments. We
do so in preparation for changing our lookup to be based on a new
payments index. We add an append duplicate function which will add a
duplicate payment with the minimum information required to successfully
read it from disk in tests.
This fixes a possible race condition during TestBreachSpends that could
cause the test to fail in a flaky way.
The error returned in PublishTransaction (publErr) could be modified by
the main test goroutine before PublishTransaction had a chance to
return, causing the wrong error value to be returned.
This was mostly visible as a flake during TestBreachSpends/all_spends
where adding a one second delay in the old code between the send in
publTx and the call to publMtx.Lock() would cause the last iteration of
the test loop to fail.
This is fixed by moving the lock and locally storing the expected error
value to before the send so that each call to PublishTransaction is
guaranteed to return the correct error value.
This is meant to handle a quirk in which key descriptors obtained
through walletrpc.DeriveKey don't result in the derived key being
persisted to the wallet's database, unlike with DeriveNextKey. Due to
this and some fallback logic in the wallet with regards to empty key
locators, if a request only specified the compressed public key, the
signature returned would be over a different key, namely the one derived
from (family=0, index=0).
