* multi: extend InvoiceDB methods with a context argument
This commit adds a context to InvoiceDB's methods. Along this refactor
we also extend InvoiceRegistry methods with contexts where it makes
sense. This change is essential to be able to provide kvdb and sqldb
implementations for InvoiceDB.
* channeldb: restrict invoice tests to only use an InvoiceDB instance
* docs: update release notes for 0.18.0
* htlcswitch/hop: use InvalidOnionVersion for replayed packets
The link will send an update_fail_malformed_htlc, so we need to set
the BADONION bit. Since there isn't a replay-specific error, we
set the failure code to InvalidOnionVersion which has the BADONION bit.
* release-notes: update for 0.17.1
For some reason lnd doesn't properly shut down on some windows itests,
and the process still running makes it impossible to access its log
files.
So for the Windows integration test, we attempt to kill the whole
process tree once the process indicates it is done.
* tlv: fuzz tests for primitives
* tlv: fuzz tests for BigSize
We use a new harness to compare decoded values instead of encoded
values, since there may be some unparsed bytes in the original data.
* tlv: fuzz tests for truncated integers
These fuzz tests are identical to non-truncated integers, except that we
allow the fuzzer to choose decode lengths shorter than the length of
normal integers.
* tlv: fuzz tests for streams
* fixup! tlv: fuzz tests for truncated integers
loop over decode length
* fixup! tlv: fuzz tests for streams
better documentation
* funding: remove unused field `newChanBarriers`
This commit removes the occurance of `newChanBarriers` as it's not used
anywhere.
* funding: rename method names to clear the funding flow
Slightly refactored the names so it's easier to see which side is
processing what messages.
* lnwallet: sanity check empty pending channel ID
This commit adds a sanity check to make sure an empty pending channel ID
will not be accepted.
Note: This commit can be dropped before merge, it's mostly added
to make the PR easier to manually test against other
implementations that have bolt 12 invoices implemented already!
This commit updates route construction to backfill the fields
required for payment to blinded paths and set amount to forward
and expiry fields to zero for intermediate hops (as is instructed
in the route blinding specification).
We could attempt to do this in the first pass, but that loop
relies on fields like amount to forward and expiry to calculate
each hop backwards, so we keep it simple (stupid) and post
processes the blinded portion, since it's computationally cheap
and more readable.
Add the option to include a blinded route in a route request (exclusive
to including hop hints, because it's incongruous to include both), and
express the route as a chain of hop hints.
Using a chain of hints over a single hint to represent the whole path
allows us to re-use our route construction to fill in a lot of the
path on our behalf.
This commit introduces a single struct to hold all of the parameters
that are passed to FindRoute. This cleans up an already overloaded
function signature and prepares us for handling requests with blinded
routes where we need to perform some additional processing on our
para (such as extracting the target node from the blinded path).
When we introduce blinded routes, some of our hops are expected
to have zero amounts to forward in their hop payload. This commit
updates our hop fee logic to attribute the full blinded route's
fees to the introduction node. We can't actually know where/how
these fees are distributed, so we collect them all at the
introduction node.
With the addition of blinded routes, we now need to account for the
possibility that intermediate nodes payloads will not have an amount
and expiry set because that information is provided by the recipient
encrypted data blob. This commit updates our payload packing to only
optionally include those fields.
This commit adds the encrypted_data, blinding_point and total_amt_msat
tlvs to the known set of even tlvs for the onion payload. These TLVs
are added in two places (the onion payload and hop struct) because
lnd uses the same set of TLV types for both structs (and they
inherently represent the same thing).
Note: in some places, unit tests intentionally mimic the style
of older tests, so as to be more consistently readable.
This commit adds a representation of blinded payments, which include a
blinded path and aggregate routing parameters to be used in payment to
the path.
This commit refactors the params used in lifecycle to prefer
`HTLCAttempt` over `HTLCAttemptInfo`. This change is needed as
`HTLCAttempt` also wraps settled and failure info, which is useful in
the following commits.
This commit turns `MPPayment` into an interface inside `routing`. Having
this interface gives us the benefit to write more granular unit tests
inside payment lifecycle. As seen from the modified unit tests, several
hacky ways of testing the `SendPayment` method is now replaced by a mock
over `MPPayment`.
This commit adds a new method, `NeedWaitAttempts`, to properly decide
whether we need to wait for the outcome of htlc attempts based on the
payment's current state.
This commit moves the struct `paymentState` used in `routing` into
`channeldb` and replaces it with `MPPaymentState`. In the following
commit we'd see the benefit, that we don't need to pass variables back
and forth between the two packages. More importantly, this state is put
closer to its origin, and is strictly updated whenever a payment is read
from disk. This approach is less error-prone comparing to the previous
one, which both the `payment` and `paymentState` need to be updated at
the same time to make sure the data stay consistant in a parallel
environment.
This commit moves the creations of hop and htlcAdd message from
`createNewPaymentAttempt` to `sendPaymentAttempt` to clean up the code
and further pave the way to decomposite the lifecycle.
This commit updates the `fee()` method in `weightEstimator` to make sure
when doing CPFP we are not exceeding the max allowed fee rate. In order
to use the max fee rate, we need to modify several methods to pass the
configured value to the estimator.
When one of the itest tranches fails, because we are running tests in
parallel, other tranches will still be running, which caused 7z to fail
at zipping the logs because race reads. This commit fixes it by making
sure we are waiting other tranches to finish before moving to zipping
and uploading the logs.
For about a year [1], the spec has prescribed encoding channel_updates
with their type prefix (0x0102) in onion failure messages. LND can
decode correctly with or without the prefix but hasn't been writing the
prefix during encoding. This commit starts writing the prefix.
