This is the final step, we actually call the interface and either
provide or retrieve the custom features over the message. We also notify
the aux components when channel reestablish is received.
This commit makes removes the `defaultQuiescenceTimeout` and makes it
configurable as different nodes have different network environment. In
addition the default timeout has been increased from 30s to 60s.
The channel should only be considered active when its pending tasks are
finished, which includes,
1. sync channel state via reestablish.
2. send previous shutdown msg.
3. reset the mailbox's packets.
4. reforwarding logs loaded from restart.
When the above tasks are finished, the channel can be considered as
fully resumed from its previous disconnection.
We now rely on the forwarding package's state to decide whether a given
packet is a reforwarding or not. If we know it's a reforwarding packet,
there's no need to check for replays in the `sharedHashes` bucket, which
behaves the same as if we are querying the `batchReplayBkt`.
Whether we should let the aux bandwidth manager decide what the
bandwidth of a channel is should also depend on whether the HTLC is a
custom HTLC, not just the channel.
In order to get more precise bandwidth reports, we also need to provide
this method with the latest htlc view. Since aux data is committed to in
the channel commitment, some uncommited HTLCs may not be accounted for,
so we need to manually provide them via the HTLC view.
This commit makes sure when processing resolutions, e.g, settling
invoices, when the link is already broken, the process would exit with
an error. This fixes the issue we found in the itest, where an
unexpected empty remote pending commitment was created although the
remote peer is already offline.
We introduce a new specific fail resolution error when the
external HTLC interceptor denies the incoming HTLC. Moreover
we introduce a new traffic shaper method which moves the
implementation of asset HTLC to the external layers.
Moreover itests are adopted to reflect this new change.
This commit updates the fn dep to the version containing the updates to
the ContextGuard implementation. Only the htlcswitch/link uses the guard
at the moment so this is updated to make use of the new implementation.
For calculating the available auxiliary bandwidth of a channel, we need
access to the inbound custom wire records of the HTLC packet, which
might contain auxiliary information about the worth of the HTLC packet
apart from the BTC value being transported.
With this commit we move the traffic shaper definition from the routing
package to the HTLC switch package as a preparation for being able to
use it there as well.
At the same time we rename it to AuxTrafficShaper to be more in line
with the other auxiliary components.
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.
All the structs defined in the `channeldb/models` package are graph
related. So once we move all the graph CRUD code to the graph package,
it makes sense to have the schema structs there too. So this just moves
the `models` package over to `graph/db/models`.
