The BOLT spec was updated and now requires the payment address for
the writer and reader. We increase the test coverage for payments
setting a wrong payment address.
Add a re-usable implementation of the sqldb.TxOptions interface and make
use of this in the various spots (invoices, batch and graph/db) where we
had previously defined individual implementations that were all doing
the same thing.
We now cancel all HTLCs of an AMP invoice as soon as it expires.
Otherwise because we mark the invoice as cancelled we would not
allow accepted HTLCs to be resolved via the invoiceEventLoop.
We always fetch the HTLCs for the specific setID, so there is no
need to keep this code. In earlier versions we would call the
UpdateInvoice method with `nil` for the setID therefore we had
to lookup the AMPState. However this was error prune because in
case one partial payment times-out the AMPState would change to
cancelled and that could lead to not resolve HTLCs.
We introduce a new specific fail resolution error when the
external HTLC interceptor denies the incoming HTLC. Moreover
we introduce a new traffic shaper method which moves the
implementation of asset HTLC to the external layers.
Moreover itests are adopted to reflect this new change.
We make sure that HTLCs which have already been decided upon
are resolved before before allowing the external interceptor to
potentially cancel them back. This makes the implementation for
the external HTLC interceptor more streamlined.
Previously, we applied replacements to our schema definitions
to make them compatible with both SQLite and Postgres backends,
as the files were not fully compatible with either.
With this change, the only replacement required for SQLite has
been moved to the generator script. This adjustment ensures
compatibility by enabling auto-incrementing primary keys that
are treated as 64-bit integers by sqlc.
Previously we'd recalculate the paid amount by summing amounts of
settled HTLCs. This approach while correct would stop the SQL migration
process as some KV invoices may have incorrectly stored paid amounts.
The current sqlc GetInvoice query experiences incremental slowdowns during
the migration of large invoice databases, primarily due to its complex
predicate set. For this specific use case, a streamlined GetInvoiceByHash
function provides a more efficient solution, maintaining near-constant
lookup times even with extensive table sizes.
Certain invoices may not have a deterministic payment hash. For such
invoices we still store the payment hashes in our KV database, but we do
not have a sufficient index to retrieve them. This PR adds such index to
the SQL database that will be used during migration to retrieve payment
hashes.
When calling `NotifyExitHopHtlc` it is allowed to pass a chan to
subscribe to the HTLC's resolution when it's settled. However, this
method will also return immediately if there's already a resolution,
which means it behaves like a notifier and a getter. If the caller
decides to only use the getter to do a non-blocking lookup, it can pass
a nil subscriber chan to bypass the notification.
Find and replace all nolint instances refering to the `lll` linter and
replace with `ll` which is the name of our custom version of the `lll`
linter which can be used to ignore log lines during linting.
The next commit will do the configuration of the custom linter and
disable the default one.
All the structs defined in the `channeldb/models` package are graph
related. So once we move all the graph CRUD code to the graph package,
it makes sense to have the schema structs there too. So this just moves
the `models` package over to `graph/db/models`.
During testing of this PR I figured out the the htlc interceptor
was not shutdown and started properly in terms of closing the
quit channel but also in terms of the relevant logs.
This commit updates the invoice registry to utilize the settlement
interceptor during the invoice settlement routine. It allows the
interceptor to capture the invoice, providing interception clients an
opportunity to determine the settlement outcome.
This commit introduces a new invoice htlc interceptor service
that intercepts invoice HTLCs during their settlement phase. It forwards
HTLCs to a subscribed client to determine their settlement outcomes.
This commit also introduces an interface to facilitate integrating the
interceptor with other packages.
Introduce `ResumeModified` action to resume standard behavior of a p2p
message with optional modifications as specified by the client during
interception.
Previously, the SQL implementation of the invoice query simply
converted the start and end timestamps to time and used them
in SQL queries to check for inclusivity. However, this logic
failed when the start and end timestamps were equal.
This commit addresses and corrects this issue.
Previously SQL invoice updater ignored the set ID hint when updating an
AMP invoice resulting in update subscriptions returning all of the AMP
state as well as all AMP HTLCs. This commit synchornizes behavior with
the KV implementation such that we now only return relevant AMP state
and HTLCs when updating an AMP invoice.
The BlindedPathConfig struct is nice for invoice creation but when we
use the Invoice message for viewing an invoice, it would be nicer to see
an "is_blinded" field.
With this PR we might call the stop method even when the start
method of a subsystem did not successfully finish therefore we
need to make sure we guard the stop methods for potential panics
if some variables are not initialized in the contructors of the
subsystems.
