Since we don't have standby nodes anymore, we don't need to close the
channels when the test finishes. Previously we would do so to make sure
the standby nodes have a clean state for the next test case, which is no
longer relevant.
This commit removes the usage of the standby nodes and uses
`CreateSimpleNetwork` when applicable. Also introduces a helper method
`NewNodeWithCoins` to quickly start a node with funds.
Prepares the upcoming refactor. We now never call `ht.Alice` directly,
instead, we always init `alice := ht.Alice` so it's easier to see how
they are removed in a following commit.
This commit adds a new flag to shuffle all the test cases before running
them so tests which require lots of blocks to be mined are less likely
to be run in the same tranch.
The other benefit is this approach provides a more efficient way to
figure which tests are broken since all the differnet backends are
running different tranches in their builds, we can identify more failed
tests in one push.
The method `AssertActiveHtlcs` is now removed due to it's easy to be
misused. To assert a given htlc, use `AssertOutgoingHTLCActive` and
`AssertIncomingHTLCActive` instead for ensuring the HTLC exists in the
right direction. Although often the case `AssertNumActiveHtlcs` would be
enough as it implicitly checks the forwarding behavior for an
intermediate node by asserting there are always num_payment*2 HTLCs.
This commit simplfies the test since we only test the preimage
extraction logic in the htlc timeout resolver, there's no need to test
it for all different channel types as the resolver is made to be
oblivious about them.
Starting from this commit, we begin the process of flattening the
multi-hop itests to make them easier to be maintained. The tests are
refactored into their own test cases, with each test focusing on testing
one channel type. This is necessary to save effort for future
development.
These tests are also updated to reflect the new `blockbeat` behavior.
To make this itest work reliably with multiple parallel SQL
transactions, we need to count both the settle and final HTLC
events. Otherwise, sometimes the final events from earlier
forwards are counted before the forward events from later
forwards, causing a miscount of the settle events. If we
expect both the settle and final event for each forward,
we don't miscount.
Find and replace all nolint instances refering to the `lll` linter and
replace with `ll` which is the name of our custom version of the `lll`
linter which can be used to ignore log lines during linting.
The next commit will do the configuration of the custom linter and
disable the default one.
Before we have sufficient signaling in the network to relay this
signal, set a zero value experimental endorsement value on the sender's
outgoing htlc. Once the network is relaying this signal and a flag day
has been set, we'll be able to set a non-zero value here.
