This commit fixes a go 1.15 vet check.
In doing so it uncovers that the time caveat check is actually reversed.
Since we should check that the caveat is added, we should only fail the
check when the caveat prefix is not equal.
There is a setting to control how often the garbage collector is run.
Apparently this is a tradeoff between CPU and memory usage. If we can
limit the memory being used in that way, this allows us to use multiple
worker again, so overall this shouldn't be much slower than before.
We fix all linter issues except for the 'lostcontext' and 'unparam' ones
as those are too numerous and would increase the diff even more.
Therefore we silence them in the itest directory for now.
Because the linter is still not build tag aware, we also have to silence
the unused and deadcode sub linters to not get false positives.
In this commit, we modify our build tag set up to allow the main test
files to be buildable w/o the current rpctest tag. We do this so that
those of us that use extensions which will compile live files like
vim-go can once again fix compile errors as we go in our editors.
In order to do this, we now make an external `testsCases` variable, and
have two variants: one that's empty (no build tag), and one that's fully
populated with all our tests (build tag active). As a result, the main
file will now always build regardless of if the build tag is active or
not, but we'll only actually execute tests if the `testCases` variable
has been populated.
As sample run w/ the tag off:
```
=== RUN TestLightningNetworkDaemon
--- PASS: TestLightningNetworkDaemon (0.00s)
PASS
ok github.com/lightningnetwork/lnd/lntest/itest 0.051s
```
SIGABRT is used by the Go runtime to forcefully terminate all
goroutines, even if they are in a deadlocked state.
It is useful in development (to get a glimpse of any potential race or
hang conditions) and in production to forcefully terminate execution
when a standard SIGQUIT won't do.
This modifies the signal package to _not_ trap SIGABRT and let it be
handled in the standard way by the runtime.
This commit adds commitQueue which is a lightweight contention manager
for STM transactions. The queue attempts to queue up transactions that
conflict for sequential execution, while leaving all "unblocked"
transactons to run freely in parallel.
For unconfirmed commit tx anchors, supply the sweeper with cpfp info and
a confirmation target fee estimate.
The sweeper will try to pay for the parent commit tx as long as the
current fee estimate exceeds the pre-signed commit tx fee rate.
Extend the fee estimator to take into account parent transactions with
their weights and fees.
Do not try to cpfp parent transactions that have a higher fee rate than
the sweep tx fee rate.
To make it possible to request a Let's Encrypt certificate by using a
different IP address where the port 80 might still be free, we add the
IP part to its configuration as well instead of just the port.
This makes it possible to use an IPv6 address for the ACME request if
all available IPv4 addresses already have their port 80 occupied.
This commit removes the duplicate tor.streamisolation option from `sample-lnd.conf` example config file (which was accidentally added in commit #104a9094980f31560ca269d3b01f000dd775778d)
With this commit we make sure that all directories where lnd could
potentially want to write files to are created on startup. This fixes
the case where the lnddir isn't set but all other paths point to
explicit locations with non-existend parent directories.
We don't create the log dir as that's done by the log rotator already.
Preparation for a cpfp-aware weight estimator. For cpfp, a regular
weight estimator isn't sufficient, because it needs to take into account
the weight of the parent transaction(s) as well.
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.
