This commit adds height-based invoice expiry for hodl invoices
that have active htlcs. This allows us to cancel our intentionally
held htlcs before channels are force closed. We only add this for
hodl invoices because we expect regular invoices to automatically
be resolved.
We still keep hodl invoices in the time-based expiry queue,
because we want to expire open invoices that reach their timeout
before any htlcs are added. Since htlcs are added after the
invoice is created, we add new htlcs as they arrive in the
invoice registry. In this commit, we allow adding of duplicate
entries for an invoice to be added to the expiry queue as each
htlc arrives to keep implementation simple. Our cancellation
logic can already handle the case where an entry is already
canceled, so this is ok.
Having it set to nil caused https://github.com/lightningnetwork/lnd/issues/5115
The problem was several layers removed from the fix. The link decides to
clean up a `fwdPkg` only if it's completed, otherwise it renotifies the
HTLCs. A package is only set to complete if it's `addAck` and
`settleFail` filters are full. For forwarded HTLCs, the `addAck` was
never being set so it would never be considered complete under this
criteria.
`addAck` is set for an HTLC when signing the next commitment TX in the
`LightningChannel`. The path for this is:
* `LightningChannel#SettleHtlc` adds the HTLC to `localUpdates`
* `LightningChannel#SignNextCommitment` builds the `ackAddRef` for all
updates with `SourceRef != nil`.
* `LightningChannel#SignNextCommitment` then passes the list of
`ackAddRef` to `OpenChannel#AppendRemoteCommitChain` to persist the new
acks in the filter
Since `SourceRef` was nil for interceptor packages, `SignNextCommitment`
ignored it and the ack was never persisted.
To distinguish the attempt's unique ID from the overall payment
identifier, we name it attemptID everywhere, and note that the
paymentHash argument won't be the actual payment hash for AMP payments.
In order to be consistent with other sub systems an error is now
returned from the Stop functions.
This also allows writing a generic cleanup mechanism to stop all
sub systems in case of a failure.

lnwire: update quickcheck tests, use constant for Error
multi: update unit tests to pass deep equal assertions with messages
In this commit, we update a series of unit tests in the code base to now
pass due to the new wire message encode/decode logic. In many instances,
we'll now manually set the extra bytes to an empty byte slice to avoid
comparisons that fail due to one message having an empty byte slice and
the other having a nil pointer.
In this commit, we modify the way we write wire messages across the
entire database. We'll now ensure that we always write wire messages
with a length prefix. We update the `codec.go` file to always write a 2
byte length prefix, this affects the way we write the `CommitDiff` and
`LogUpdates` struct to disk, and the network results bucket in the
switch as it includes a wire message.
This commit caps the update fee the initiator will send when the anchors
channel type is used. We do not limit anything on the receiver side.
10 sat/vbyte is the current default max fee rate we use. This should be
enough to ensure propagation before anchoring down the commitment
transaction.
* mod: bump btcwallet version to accept db timeout
* btcwallet: add DBTimeOut in config
* kvdb: add database timeout option for bbolt
This commit adds a DBTimeout option in bbolt config. The relevant
functions walletdb.Open/Create are updated to use this config. In
addition, the bolt compacter also applies the new timeout option.
* channeldb: add DBTimeout in db options
This commit adds the DBTimeout option for channeldb. A new unit
test file is created to test the default options. In addition,
the params used in kvdb.Create inside channeldb_test is updated
with a DefaultDBTimeout value.
* contractcourt+routing: use DBTimeout in kvdb
This commit touches multiple test files in contractcourt and routing.
The call of function kvdb.Create and kvdb.Open are now updated with
the new param DBTimeout, using the default value kvdb.DefaultDBTimeout.
* lncfg: add DBTimeout option in db config
The DBTimeout option is added to db config. A new unit test is
added to check the default DB config is created as expected.
* migration: add DBTimeout param in kvdb.Create/kvdb.Open
* keychain: update tests to use DBTimeout param
* htlcswitch+chainreg: add DBTimeout option
* macaroons: support DBTimeout config in creation
This commit adds the DBTimeout during the creation of macaroons.db.
The usage of kvdb.Create and kvdb.Open in its tests are updated with
a timeout value using kvdb.DefaultDBTimeout.
* walletunlocker: add dbTimeout option in UnlockerService
This commit adds a new param, dbTimeout, during the creation of
UnlockerService. This param is then passed to wallet.NewLoader
inside various service calls, specifying a timeout value to be
used when opening the bbolt. In addition, the macaroonService
is also called with this dbTimeout param.
* watchtower/wtdb: add dbTimeout param during creation
This commit adds the dbTimeout param for the creation of both
watchtower.db and wtclient.db.
* multi: add db timeout param for walletdb.Create
This commit adds the db timeout param for the function call
walletdb.Create. It touches only the test files found in chainntnfs,
lnwallet, and routing.
* lnd: pass DBTimeout config to relevant services
This commit enables lnd to pass the DBTimeout config to the following
services/config/functions,
- chainControlConfig
- walletunlocker
- wallet.NewLoader
- macaroons
- watchtower
In addition, the usage of wallet.Create is updated too.
* sample-config: add dbtimeout option
Since it turned out borking channels on every received error could cause
us to bork channels in case of a sync error with C-lightning, we revert
this for now.
Similarly as with kvdb.View this commits adds a reset closure to the
kvdb.Update call in order to be able to reset external state if the
underlying db backend needs to retry the transaction.
This commit adds a reset() closure to the kvdb.View function which will
be called before each retry (including the first) of the view
transaction. The reset() closure can be used to reset external state
(eg slices or maps) where the view closure puts intermediate results.
