Add an optional channel status CloseChannel which will be stored on the
hitsorical channel which is persisted at channel close. This status is
used to set the close initiator for channels that do not complete the
funding flow or we abandon. In follow up commits, this status will be
used to record force and breach closes. The value is written to the
historical channel bucket for diplay over rpc.
This commit adds two new channel statuses which indicate the party that
initatited closing the channel. These statuses are set in conjunction
with the existing commit broadcast status so that we do not need to
migrate existing logic to handle multiple types of closes. This status
is set for locally initiated force closes in this commit because they
follow a similar pattern to cooparative closes, marking the commitment
broadcast then proceeding with tx broadcast. Remote force closes are
added in the following commit, as they are handled differently.
This changes replaces the pending an waiting booleans in fetchChannels
with optional filters which can be more flexibly used. This change
allows filtering of channels without having to reason about the matrix
of possible boolean combinations. A test is added to ensure that the
combinations of these filters act as expected.
This commit updates the channel state machine to
persistently store remote updates that we have received a
signature for, but that we haven't yet included in a commit
signature of our own.
Previously those updates were only stored in memory and
dropped across restarts. This lead to the production of
an invalid signature and channel force closure. The remote
party expects us to include those updates.
This commit removes channeldb.FetchAllInvoices and changes tests such
that expectation sets are prepared in the test case instead of selected
from the DB.
This commit adds handling code for the key send custom record. If this
record is present and its hash matches the payment hash, invoice
registry will insert a new invoice into the database "just in time". The
subsequent settle flow is unchanged. The newly inserted invoice is
picked up and settled. Notifications will be broadcast as usual.
This field isn't optional. It was introduced in
5ed31b1030176374d4184fee0b80ae7679e0e355 which was part of release
0.4.0. This release contained breaking database changes, so it is safe
to assume that from there on the field is always populated.
If there would still be empty payment request fields in the wild, users
would also experience issues with ListInvoices. ListInvoices decodes the
payment request.
This commits builds on top of PR #3694 to further clarify invoice
state by defining pending invoices as the ones which are not
settled or canceled. Automatic cancellation of expired invoices
makes this possbile. While this change only directly affects
ChannelDB, users of the listinvoices RPC will receive actual
pending invoices when pending_only flag is set.
Previously we would return nil features when we didn't have a node
announcement or a given node. With this change, we can always assume the
feature vector is populated during pathfinding.
This commit changes how FetchAllInvoicesWithPaymentHash behaves
when the DB is empty and also adds a unit test to test that
case as well as normal expected behavior.
This commit adds InvoiceExpryWatcher which is a separate class that
receives new invoices (and existing ones upon restart) from InvoiceRegistry
and actively watches their expiry. When an invoice is expired
InvoiceExpiryWatcher will call into InvoiceRegistry to cancel the
invoice and by that notify all subscribers about the state change.
This commit prepares for more manipulation of custom records. A list of
tlv.Record types is more difficult to use than the more basic
map[uint64][]byte.
Furthermore fields and variables are renamed to make them more
consistent.
Before we change the Hop struct, isolate the code that is used in older
migrations to prevent breaking them.
route.go was taken from commit 6e463c1634061d595953f20813860207e5d485ce
Previously the cancel and add actions were combined in a single map.
Nil values implictly signaled cancel actions. This wasn't very obvious.
Furthermore this split prepares for processing the adds and cancels
separately, which is more efficient if there are already two maps.
This commit moves the update code into its own function as a preparation
for extending the logic further for mpp.
In order to make this change cleanly, structured result codes are
introduced. This also prepares for a future htlc notifier rpc hook that
reports htlc settle decisions to external applications.
Furthermore the awkward use of errNoUpdate as a way to signal no update
is removed.
