This commit again enables anchor channels by default.
During itests we still keep anchors opt-in, as many of the tests rely on
the behaviour of non-anchor channels.
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.
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.
In this commit, we fix a bug that would cause resolution of items in
/etc/hosts (or the like) to fail as Tor wouldn't recognize them as
proper host names. With this commit, we'll catch this error and fall
back to the system's resolver.
With this commit, if --tor.active is specified, then IPv6 addresses
will no longer go through the connmgr.TorLookupIP function from btcd.
This function does not have proper IPv6 support and would fail with
the error "tor general error". Instead, use the system resolver.
This commit reverts the anchors-by-default change, and instead make
anchor commitments and opt-in option. The plan is to enable anchors by
default further down the line.
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.
Add a new health check package which will periodically poll health
check functions and shutdown if we do not succeed after our set number
of attempts. The first check that we add is one for our chain backend,
to ensure that we are connected to a bitcoin node.
In this commit, we modify the existing `GetBackend` method to now be
called `GetBackends`. This new method will populate a new `RemoteDB`
attribute based on if the replicated backend is active or not. As is,
the local backend is used everywhere. An upcoming commit will once again
re-enable the remote backend, in a hybrid manner.
In this commit, unify the old and new values for `sync-freelist`, and
also ensure that we don't break behavior for any users that're using the
_old_ value.
To do this, we first rename what was `--db.bolt.no-sync-freelist`, to
`--db.bolt.sync-freelist`. This gets rid of the negation on the config
level, and lets us override that value if the user is specifying the
legacy config option.
In the future, we'll deprecate the old config option, in favor of the
new DB scoped option.
In this commit, we split off the protocol options into a normal and
legacy sub-config. The legacy sub-config protected by a built tag, and
will only be populated if thet tag is set. Legacy options now have a
`legacy` prefix. So `--protocol.legacyonion` is now `--protocol.onion`,
and `--protocol.committweak`, is now `--protocol.legacy.committweak`.
We also create a new experimental protocol feature sub-config for newer
features that may not yet been fully complete, so they require a build
tag.
This commit extends etcd db with namespaces without additional storage
space requirements. This is simply done by instead of using an all zero
root bucket id, we use the sha256 hash of the name space as our root
bucket id.
This commit separates all etcd related sources (sans a few stubs and
config) from the rest of the source tree and makes compilation conditional
depending on whether the kvdb_etcd build tag is specified.
This commit extends lncfg to support user specified database backend.
This supports configuration for both bolt and etcd (while only allowing
one or the other).
In this commit, we extend the current SCB recovery tests to also cover
the new anchor commitment type. We only add a single test that covers
the most common case to avoid needing to tests all cases for all
commitment types which is being done in a follow up PR.
In this commit, we add a new legacy protocol command line flag:
`committweak`. When set, this forces the node to NOT signal usage of the
new commitment format. This allows us to test that we're able to
properly establish channels with legacy nodes. Within the server, we'll
now gate our signalling of this new feature based on the legacy protocol
config. Finally, when accepting/initiating a new channel funding, we'll
now check both the local and remote global feature bits, only using the
new commitment format if both signal the global feature bit.
In this commit, we add a new build tag protected sub-config for legacy
protocol features. The goal of this addition is to be able to default to
new feature within lnd, but expose hooks at the config level to allow
integration tests to force the old behavior to ensure that we're able to
support both the old+new versions.
With the introduction of the WatchtowerClient RPC subserver, the lnd
configuration flag to specify private watchtowers for the client is no
longer needed and can lead to confusion upon users. Therefore, we remove
the flag completely, and only rely on the watchtower client being active
through a new --wtclient.active flag.
Start the Prometheus exporter in rpcserver.go if monitoring is enabled through the
build tag. Also allow users to specify what address they want the Prometheus
exporter to be listening on.
Now that the write pool no longer executes blocking i/o operations, it
is safe to reduce this number considerably. The write pool now only
handles encoding and encryption of messages, making problem
computationally bound and thus dependent on available CPUs. The
descriptions of the workers configs is also updated to explain how users
should set these on their on machines.
TCP addresses resolved through net.ResolveTCPAddr give a default network
of "tcp", so we'll map back the correct network for the given address.
This ensures that we can listen on the correct interface (IPv4 vs IPv6).
This commit introduces the Validator interface, which
is intended to be implemented by any sub configs. It
specifies a Validate() error method that should fail
if a sub configuration contains any invalid or insane
parameters.
In addition, a package-level Validate method can be
used to check a variadic number of sub configs
implementing the Validator interface. This allows the
primary config struct to be extended via targeted
and/or specialized sub configs, and validate all of
them in sequence without bloating the main package
with the actual validation logic.
Bumps the default read and write handlers to be well
above the average number of peers a node has. Since
the worker counts specify only a maximum number of
concurrent read/write workers, it is expected that
the actual usage would converge to the requirements
of the node anyway. However, in preparation for a
major release, this is a conservative measure to
ensure that the default values aren't too low and
improve network instability.
