This commit adds gives BtcdNotifier access to the block cache and wraps
its GetBlock method so that the block cache's mutex map for the specific
hash is used.
Adding persistency to neutrino re-scan progress. In case the re-scan
failed in the middle or the node was restarted before the re-scan
has been completed this fix will start from the last point instead
of the beginning.
On long re-scan , such as old channels on mobile devices this is
crucial.
* 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
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.
When we cancel a confirmation request, we should remove the request from
the height map regardless of the current height. Otherwise we end up in
the situation when the height is reached, the notification is attempted
sent which results in a crash.
If a concurrent call to cancel is made while the notifier is shutting
down, this would cause a panic (close of closed channel) since the
events are not removed from the notification sets.
This addresses a panic when a notification is canceled after its been
detected as included in a block and before its confirmation notification
is dispatched.
This commit introduces an optimization for the chain scanning
used in historical confirmations notifications.
It now uses batch request instead of requesting filters one by one.
Earlier GetCFilter could return a nil-error along with a nil-filter in
cases where we failed to fetch the filter. We would just ignore the
block causing us to miss potential crucial information.
Now that GetCFilter will return an error in cases where the fetch
failed, the filter will never be nil (even for blocks with only coinbase
transactions), and we'll instead return an error.
We also increase the number of retries for the filter from the default 2
to 5.
We would establish the connection to the chain backend and start getting
block notifications before we had started the concurrent queues, which
would lead to the OnBlockConnected call being blocked, and a deadlock
(since GetBestBlock would never return).
Instead we make sure to start the queues before establishing the
connection, consuming the notifications right away.
