We risked deadlocking on shutdown if a client (in our case a contract
resolver) attempted to schedule a sweep of an input after the
ChainNotifier had been shut down. This would cause the `collector`
goroutine to exit, and not handle incoming requests, causing a deadlock
(since the ChainArbitrator is being stopped before the Sweeper in the
server).
To fix this we could change the order these subsystems are stopped, but
this doesn't ensure there aren't other clients that could end up in the
same deadlock scenario. So instead we keep handling the incoming
requests even after the collector has exited (immediatly returning an
error), until the sweeper is signalled to shutdown.
This commit unsets option static remote key required for peers that
we have existing legacy channels with. This ensures that we can still
connect to peers that do not recognize this feature bit that we have
existing channels with.
To avoid running into the "server is still starting" error when trying
to close a channel, we first wait for the error to disappear before we
try closing the actual channel.
This commit replaces most of the hard coded 10, 15, 20 and 30 second
timeouts with the default timeout. This should allow darwin users to
successfully run the parallel itests locally as well.
It seems that our itests don't perform correctly in a high CPU usage
scenario such as running 6 tests in parallel. Some goroutines don't get
enough execution time and causes check to time out.
By reducing the total number of parallel tests, we hope to give all
goroutines some more breathing room.
In high CPU usage scenarios such as our parallel itests, it seems that
some goroutines just don't get any CPU time before our test timeouts
expire. By polling 10 times less frequently, we hope to reduce the
overall number of goroutines that are spawned because of the RPC
requests within the polling code.
This add a test for inputs that gets re-ordered because the inputs with
required TxOuts must be added first.
We add a new step to the test that checks that all inputs were signed at
the correct tx input index.
This test would fail without the previous commit.
This commit fixes an issue that would arise if inputs without required
TxOuts would be swept together with inputs with required TxOuts. In this
case we would add the required ones first to the transaction, but did
not change the order we signed the inputs, resulting in signing the
wrong input index.
* 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 ensures that the nodes will properly be shutdown even if one fails
to start or any of them fail to connect. Previously the shutdown is
defered only in the event that the setup was successful.
Certain checks were implemented with Errorf, which only logs the
failure. This results in the test harness panicking further down. We go
further ahead and convert all calls in this file to use require.
To make sure we build the exact version of btcd that is referenced in
the project's go.mod file and to not overwrite any binary the user might
already have installed on the system, we compile btcd into an explicit
file in the itest directory.
This should also speed up invocations of "make itest-only" because the
test harness doesn't always compile btcd on its own.
We also fix a bug with the version parsing where adding a "replace"
directive in the go.mod would result in the awk commands to extract the
wrong version. Because we no longer use the DEPGET goal to build and
install btcd, using a replace directive now actually works for itests.
To remove the need to have an extra make goal for the Windows itests, we
instead add the flag windows=1 that sets the make variable EXEC_SUFFIX
to properly add the ".exe" suffix to all executable names.
To make the Makefile a bit easier to understand, we remove the implicit
ITEST goal/command variable and switch all itest execution over to
explicit goals in the main Makefile.
With the new btcd version we can specify our own listen address
generator function for any btcd nodes. This should reduce flakiness as
the previous way of getting a free port was based on just picking a
random number which lead to conflicts.
We also double the default values for connection retries and timeouts,
effectively waiting up to 4 seconds in total now.
