This commit adds the block cache to the CfFilteredChainView struct
and wraps its GetBlock function so that block cache mutex map is used
when the call to neutrino's GetBlock function is called.
* 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 this commit, we update the build to point to the latest version of
neutrino and btcwallet. The latest version of neutrino includes a number
of bug fixes, and new features like reliably transaction broadcast. The
latest version of btcwallet contains a number of bug fixes related to
properly remove invalid transactions from its database.
In this commit, we introduce a nice optimization with regards to lnd's
interaction with a bitcoind backend. Within lnd, we currently have three
different subsystems responsible for watching the chain: chainntnfs,
lnwallet, and routing/chainview. Each of these subsystems has an active
RPC and ZMQ connection to the underlying bitcoind node. This would incur
a toll on the underlying bitcoind node and would cause us to miss ZMQ
events, which are crucial to lnd. We remedy this issue by sharing the
same connection to a bitcoind node between the different clients within
lnd.
In this commit, we modify the test to explitlcy give the neutrino
backend more time to catch up compared to the RPC backends. We do this
as a recent change has been made in the neutrino backend to wait for the
filter headers to finish syncing before proceeding with the rescan
itself. As a result, we'll need to account for this in the test and
sleep enough to give the backend a chance to catch up.
In this commit, we ensure that the neutrino backend meets the target
interface, and also we update the API usage for the internal neutrino
rescan struct to use the new InputWithScript struct.
In this commit, we update the existing UpdateFilter method to take the
new channeldb.EdgePoint struct in place of the prior wire.OutPoint. We
must do this as the caller now typically has this type due to the
preparation to enable lnd to be able to be compatible with the new
neutrino protocol.
In this commit, we modify the granularity of the locking
around the filterMtx in the bitcoind chainview, such that
we only lock once per block connected or filter update.
Currently, we acquire and release the lock for every
update to the map.
We also fix a bug that would cause us to not fully remove
all previous outpoints spent by a txn when doing manual
filter, as we previously would only remove the first output
detected.
In this commit, we modify the granularity of the locking
around the filterMtx in the btcd chainview, such that we
only lock once per block connected or filter update.
Currently, we acquire and release the lock for every
update to the map.
We also fix a bug that would cause us to not fully remove
all previous outpoints spent by a txn when doing manual
filter, as we previously would only remove the first output
detected.
This commit alters the neutrino chainview such that it
caches the filter entries corresponding to watched
outpoints at the moment they are added to the filter.
Previously, we would rederive each filter entry when
reconstructing the relevant filter entries, which
would lead to unnecessary work on the gc. Now, each is
created at most once, and reused across subsequent
reconstructions.
This commit adds a test for the FilteredChainView interfaces,
making sure they notify about disconnected/connected blocks
in the correct order during a reorg.
This commit makes use of the blockEventQueue within the neutrino
implementation of FilteredChainView to ensure connected and
disconnected blocks are consumed in order by the reader.
It also specifies that neutrino is not to send disconnected blocks
notifications during rescans, making it consistent with the btcd
implementation.
This commit moves btcd view away from using the deprecated
callbacks onBlockConnected/Disconnected, and instead use
onFilteredBlockConnected/disconnected.
This commit also implements the sending of disconnected blocks
over the staleBlocks channel. To send these blocks, the
blockEventQueue is used to ensure the ordering of blocks are
correctly kept.
It also changes the way filter updates are handled. Since we
now load the tx filter to the rpc server itself, we can call
RescanBlocks instead of manually filtering blocks. These
rescanned blocks are also added to the blockEventQueue,
ensuring the ordering is kept.
blockEventQueue is an ordered queue for block events sent from a
FilteredChainView. The two types of possible block events are
connected/new blocks, and disconencted/stale blocks. The
blockEventQueue keeps the order of these events intact, while
still being non-blocking. This is important in order for the
chainView's call to onFilteredBlockConnected/Disconnected to not
get blocked, and for the consumer of the block events to always
get the events in the correct order.
This commit reduces the neutrino.WaitForMoreCFHeaders parameter when
instantiating a neutrino instance as a lower value will allow the tests
to complete more quickly.
