Since private channels (most likely) won't be used for routing other
than as last hop, they bear a smaller risk that we must quickly force
close them in order to resolve a HTLC up/downstream.
In the case where it actually has to be force to resolve a payment (if
it is the first/last hop on a routed payment), we can assume that the
router will have UTXOs available from the reserved value from the
incoming public channel.
We cap the maximum value we'll reserve for anchor channel fee bumping at
10 times the per-channel amount such that nodes with a high number of
channels don't have to keep around a very large amount for the unlikely
scanario that they all close at the same time.
This commit ensures that for the neutrino implementation of
lnwallet.BlockChainIO, the neutrino GetBlock method is called directly
(since it already uses the blockcache). It also ensures that the block
cache mutex for the given hash is locked before the call to GetBlock.
The previous behavior would allow updates to be overwritten in some
scenarios. Upon restart, this would lead to a missing settle/fail in
the update logs.
Add a dust-limit to `CoinSelect` and let the fee estimation consider if a change output is needed or not, assuring that if the change is below the dust-limit it will go towards the fee instead.
This commit adds a RevocationKeyLocator field to the OpenChannel
struct so that the SCB derivation doesn't have to brute-force the
sha chain root key and match the public key. ECDH derivation is now
used to derive the key instead of regular private key derivation a
la DerivePrivKey. The legacy can still be used to recover old
channels.

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.
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
