Previously we waited only for the number of channels to become what we
expected, but this wasn't enough. Sometimes the agent had't yet updated
its internal balance, causing the test to fail with an unexpected
balance.
To make the autopilot able to account for fees, we let it use the
subtractFees option when opening channels.
This makes sure that each channel we attempt to open will eat at most
Amt out of our budget. Previously fees would eat into our funds in
addition, causing us to deplete our funds more than expected on each
channel opening.
TestFundingManagerFundAll tests that we can initiate a funding request to
use the funds remaining in the wallet. This should produce a funding tx with
no change output.
This commit adds a SubtractFees option to the funding request, letting
the caller specify that the fees should be deducted from the funding
amount. This paves the way for letting the funding manager spend up to a
given amount when creating a channel, like the rest of the funds in the
wallet.
This makes the method independent of the ChannelContribution struct.
We also add a function closure to the return of selectCoinsAndChange,
that let is unlock the selected output in case of error.
This commit makes the funding manager access the MaxPendingChannels and
RejectPush values from the fundingConfig instead of the global config
struct.
Done to avoid sharing state between tests.
In this commit, we establish a new pattern to always log errors before
returning them to the higher level caller, which then prints the error
to stdout/stderr. Errors returned are usually lowercase, but we decide
not to apply this rule here as these errors should not be chained
forward.
In this commit, we publicly export the `word` field as it makes it
easier to programmatically interact with the package when attempting to
re-derive proper `cipherseed` instances. We also add a new `Index` field
as well to provide additional context for programmatic manipulating of
seeds.
We stopped requesting this from other nodes as it is very expensive as
the graph continues to grow. In this commit we will also stop
responding, as nodes are recommended to begin using the `gossip_queries`
and upcoming `extended_gossip_queries` to reconcile missing graph data.
A cleanup closure is not included when an error is returned, causing the
defer to execute and triggering the following panic:
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x105da38]

If nodes return a channel policy related failure, they may get a second
chance. Our graph may not be up to date. Previously this logic was
contained in the payment session.
This commit moves that into global mission control and thereby removes
the last mission control state that was kept on the payment level.
Because mission control is not aware of the relation between payment
attempts and payments, the second chance logic is no longer based
tracking second chances given per payment.
Instead a time based approach is used. If a node reports a policy
failure that prevents forwarding to its peer, it will get a second
chance. But it will get it only if the previous second chance was
long enough ago.
Also those second chances are no longer dependent on whether an
associated channel update is valid. It will get the second chance
regardless, to prevent creating a dependency between mission control and
the graph. This would interfer with (future) replay of history, because
the graph may not be the same anymore at that point.
This flake was caused by the rpcserver receiving a CloseChannel request
before Alice's channel event subscription request, causing Alice to miss one
notification. As a result, we move Alice's subscription to the beginning of the
test.
Additionally, we add a check to ensure the opening notifications are
received in the right order.
This commit adds the pubkeyIndices map to the distanceHeap to avoid
duplicate entries on the heap. This happened in the earlier iteration
of the findPath algorithm and would cause the driving loop to
evaluate already evaluated entries when there was no need.
