In this commit, we expose a new monitoring option to allow users to
export gRPC performance metrics. These metrics can be used to see how
long certain calls are taking, the total amount of time spent handling
calls, broken down by service and also call.
This option consumes additional memory and disk space for the Prometheus
server, which is why we're opting to make it an optional flag.
To enable converting an existing wallet with private key material into a
watch-only wallet on first startup with remote signing enabled, we add a
new flag. Since the conversion is a destructive process, this shouldn't
happen automatically just because remote signing is enabled.
Unfortunately, we can't use the graph cache directly here as it doesn't
include all the information we need, since it only includes the minimal
amount of information needed for path finding.
Instead, we use a simple mutex guarded cache that evicts itself after a
certain interval. The default is set small enough that most users
shouldn't really notice. We also provide a way to disable the cache, and
also disable the cache in the itests.

payments-expiration-grace-period needs time unit h/m/s or else the lnd does not start.
; payments-expiration-grace-period=30s
Corrected minor typo.
This commit adds a new health check, tor connection, to our liveness
monitor. A monitor refactor is applied to the server creation such that
the scope of health check creation is managed within one function.
In this commit we add an extra config for enabling logging to an
external file when using embedded etcd. This can be useful when running
integration tests to see more details about etcd related issues.
As requested by users of node bundle software. They want to use the
wallet-unlock-password-file configuration option in their
default/template config file. This makes the first-time lnd setup a bit
more tricky since lnd will fail with an error if no wallet exists yet
while that config option is used.
The new wallet-unlock-allow-create option instructs lnd to not fail if
no wallet exists yet but instead spin up its unlocker RPC as it would
without the wallet-unlock-password-file being present.
This is not recommended for auto-provisioned or high-security systems
because the wallet creation RPC is unauthenticated and an attacker could
inject a seed while lnd is in that state.
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.
In automated or unattended setups such as cluster/container
environments, unlocking the wallet through RPC presents a set of
challenges. Usually the password is present as a file somewhere in the
container already anyway so we might also just read it from there.
This commit also changes the order of DB init to be run after the RPC
server is up. This will allow us to later add an RPC endpoint to be used
to query leadership status.
In this commit we add a new flag that controls if lnd will do strict
zombie pruning or not. If true, then this will cause lnd to maintain a
tighter graph as it wants both edges to always be live. We enable this by
default for neutrino as without this, it's possible that a node never
sees both edges begin disabled, so those edges are never actually pruned
from the graph.
This commit uses the new coop-close-target-confs value as the default to
use for a nodes self initiated channel closures if the conf-target flag
for the channel closure is not set. The defaults for both these options
is 6 so this shouldnt change current behaviour.
This commit adds a new config option: "--coop-close-target-confs"
which allows a user to override the default target confirmations of 6
that is used to estimate a fee rate to use during a co-op closure
initiated by a remote peer.
A new top level feeurl option was added recently to replace the neutrino.feeurl
option. The new option was never added to the sample config file and the
text was never updated to reflect that the option is required for
neutrino on mainnet. We fix this and also add a valid mainnet example
URL to the sample config file.
* 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
In certain container set ups, it's useful to optionally have lnd just shutdown if it detects that its certs are expired, as assuming there's a hypervisor to restart the container/pod, then upon restart, lnd will have fully up to date certs.
To allow nodes more control over the amount of time that their funds
will be locked up, we add a MaxLocalCSVDelay option which sets the
maximum csv delay we will accept for all channels. We default to the
existing constant of 10000, and set a sane minimum on this value so that
clients cannot set unreasonably low maximum csv delays which will result
in their node rejecting all channels.
Because we'll add a check that enforces all command line flags that are
available with the default build tags to also be contained in the
sample-lnd.conf file, we first add all that currently are missing.
This commit removes the duplicate tor.streamisolation option from `sample-lnd.conf` example config file (which was accidentally added in commit #104a9094980f31560ca269d3b01f000dd775778d)
This commit enables lnd to request and renew a Let's Encrypt
certificate. This certificate is used both for the grpc as well as the
rest listeners. It allows clients to connect without having a copy of
the (public) server certificate.

- let users specify their MAXIMUM WUMBO with new config option which sets the maximum channel size lnd will accept
- current implementation is a simple check by the fundingManager rather than anything to do with the ChannelAcceptor
- Add test cases which verify that maximum channel limit is respected for wumbo/non-wumbo channels
- use --maxchansize 0 value to distinguish set/unset config. If user sets max value to 0 it will not do anything as 0 is currently used to indicate to the funding manager that the limit should not be enforced. This seems justifiable since --maxchansize=0 doesn't seem to make sense at first glance.
- add integration test case to ensure that config parsing and valiation is proper. I simplified the funding managers check electing to rely on config.go to correctly parse and set up either i) non wumbo default limit of 0.16 BTC OR ii) wumbo default soft limit of 10 BTC

When starting up with lnd.conf that contains the sample line
"tor.active", lnd crashes and prints the error:
malformed key=value (tor.active)
Using "tor.active=true" instead works as expected.
In this commit, we update the `sample-lnd.conf` example config file to
be up to date with all the new configuration parameters we've added over
the past few release.
