This is useful when we wish to have a channel frozen for a specific
amount of blocks after its confirmation. This could also be done with an
absolute thaw height, but it does not suit cases where a strict block
delta needs to be enforced, as it's not possible to know for certain
when a channel will be included in the chain. To work around this, we
add a relative interpretation of the field, where if its value is below
500,000, then it's interpreted as a relative height. This approach
allows us to prevent further database modifications to account for a
relative thaw height.
Adds a new configuration flag to lnd that will keep keysend payments in
the accepted state. An application can then inspect the payment
parameters and decide whether to settle or cancel.
The on-the-fly inserted keysend invoices get a configurable expiry time.
This is a safeguard in case the application that should decide on the
keysend payments isn't active.
Avoids indexing the all-zeros pay addr, since it is still in use by
legacy keysend. Without this, the pay addr index will reject all but the
first keysend since they will be detected as duplicates within the set
id index.
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.
This fixes a decoding error when the list of short channel ids within a
QueryShortChanIDs message started with a zero sid.
BOLT-0007 specifies that lists of short channel ids should be sorted in
ascending order. Previously, this was checked within lnwire by comparing
two consecutive sids in the list, starting at the empty (zero) sid.
This meant that a list that started with a zero sid couldn't be decoded
since the first element would _not_ be greater than the last one
(namely: also zero).
Given that one can only check for ordering starting at the second
element, we add a check to ensure the proper behavior.
A unit test is also added to ensure no future regressions on this
behavior.
In this commit we add the ability to intercept forwarded htlc packets
straight from the RPC layer. The RPC layer handles a bidrectional stream
that comminucates to the client the intercepted packets and handles its
response by coordinating with the interceptable switch.
