This test reproduces a bug in the `cln-plugin`-crate.
Core Lightning supports a wildcard `*` that plugins can use to
subscribe to all notifications.
However, `cln-plugin` does not support this case.
It allows the developer to subscribe `*`.
But the plug-in crashes when the first notification is received
Uncommited channels are missing several fields which would normally be
populated by an active channel. This simply skips them for the purposes
of finding a route. The particular culprit was:
{
"peer_id": "038cd9f3679d5b39bb2105978467918d549572de472f07dd729e37c7a6377d41d5",

Rather than `allow_broken_log`, we have `broken_log` which is a regex
indicating what log lines are expected. This tightens our tests
significantly, as it will catch *unexpected* brokenness.

Apparently NixOS didn't have Python (sometimes!) so let's not assume.
By reusing the JSON "parsing" code from cowsay, we can self-disable

Changelog-Fixed: Plugins: `clnrest` now correctly self-disables if Python not present at all.
Tests whether we're able to route around a low-fee channel in the graph. We
should be able to find the more expensive route if the cheaper route is
depleted.
In the Min. Cost Flow solver we put a constraint on arcs capacities,
such that the total flow that can be allocated through a channel does
not exceed htlc_max. This solves two previous problem of the htlc_max
constraint at the MCF level.
Add spendable/receivable and is_local fields to the callback function
used in gossmods_from_listpeerchannels. This allows to do more fine
grained use of the listpeerchannels call.
The first use case is renepay, for which we need to ignore the htlc_max
of the local channels only.
I was trying to debug test_zeroconf_open and getting very confused.
The reason: l0 is lightning-1, l1 is lightning-2, etc! And there are
two other tests where an l0 has been added at the front: fix them all
to avoid future confusion!

Watchtowers changed the code so that we *always* have a channel->shutdown_scriptpubkey[LOCAL]
(see new_channel()). The previous code had several problems:
1. It tested this for NULL, unnecessarily.
2. It allowed overriding if it was a default, *even* if we were already using it.
3. If the peer opened without option_shutdown_anysegwit, but upgraded before we closed,
we would not recognize the default.
4. It set the final scriptpubkey (and other things!) even if the command failed.
Changelog-Fixed: JSON-RPC: `close` with `destination` works even if prior `destination` was rejected.

Whenever there is a payment failure that requires gossip update, for
example changing the fee rates of remote channels, we call addgossip.
For renepay to consider this changes in the coming payment attempts, it
must update gossmap.
- previous pending sendpays must add up so that the plugin tries to pay
the rest of the amount,
- avoid groupid, partid collisions,
- add shadow fees if the option is set and the payment amount - total
delivering = 0
- add a test,
- also fix a buggy shadow routing test
This avoids us gossiping about nodes which don't have live channels.
Interstingly, we previously tested that we *did* gossip such node
announcements, and now we fix that test.
