This commit makes sure that no loop variables or other temporary
variables are accessed directly in a goroutine but are instead passed
into the goroutine through a parameter. This makes sure a copy of the
value is put on the stack and is not changed while the outside loop
continues.
This commit was previously split into the following parts to ease
review:
- 2d746f68: replace imports
- 4008f0fd: use ecdsa.Signature
- 849e33d1: remove btcec.S256()
- b8f6ebbd: use v2 library correctly
- fa80bca9: bump go modules
We update several of our integration tests that exercise different
scenarios with regards to the broadcast of a channel commitment
transaction with HTLCs in-flight to use the new commitment type for
channel leases. We do this to ensure we have complete coverage of said
channel commitment type. This required changing several assumptions
throughout the tests based on when we should expect sweeps to happen.
This commit fixes the issue where a wrong context being inherited to
create a timeout context. When a parent context timed out, all its
children contexts also timed out, even the children contexts had a
larger timeout value. This means it only makes sense to inherite from a
parent when its children have smaller timeout value. Given the setup of
the itest, all the timeout contexts need to be created from a context
background(hence no timeout on the parent) unless there's an explicit
timeout bound we want to set.
