Most user-contributed plugins are written in python, and not having it
available in the docker image is rather annoying to work around. So we just
add that tiny dependency to the image.

Fixes: #3815
Changelog-Fixed: Fixed a deviation from BOLT#2: if both nodes advertised `option_upfront_shutdown_script` feature: MUST include ... a zero-length `shutdown_scriptpubkey`.
By setting nLocktime to the current block, the reorg test
"test_funding_reorg_remote_lags" actually drops the funding transaction
entirely when a reorg happens.
Except the 1 in 10 cases where nLocktime is randomly set to 1-10
blocks earlier.
This implies, strongly, that we hit "restart" too often on Travis.

We could end up with multiple channel hints, which is a bit wasteful. We now
look for existing ones before adding a new one, and if one exists we use the
more restrictive parameters.

We're lucky that we can distinguish the severity of the failure based on the
failcode, so we bubble up the one with the maximum failcode, and let callers
inspect details if they need more information.
There is a race between `getroute` learning that our peer accepts TLVs and us
initiating the payment. Waiting for announcements ensures we always use TLVs,
matching our expectation in the test / plugin.
We can have quite detailed information about our local channels, so call
`listpeers` before the `getroute` call on the root payment, to seed that
information in the channel_hints.
Since we end up consolidating some of the return values for `pay` and
`paystatus` and change the public interface we need to add the compatibility
flag and guard the switchover behind it.
most likely unused since the switch to libwally for internal blockchain
things.
these method names were clashing with ones that are to be introduced
with some libwally cleanups, so getting rid of them pre-emptively keeps
us libwally compatible
libwally's API requires us to pass in NULL pointers if the array size is
zero, so we update our array from wire-er to comply with this
requirement
[ Added fix to avoid tal_resize() of NULL -- RR ]
Changelog-Changed: `txprepare` now prepares transactions whose `nLockTime` is set to the tip blockheight, instead of using 0. `fundchannel` will use `nLockTime` set to the tip blockheight as well.
Trying to rework the TLV streams to have a more homogenous interface to work
with. This is by no means a complete implementation, just the groundwork that
is going to be used by the wire code generator to generate the specific
accessors, but it's enough so we can manipulate TLV streams in the onion and
later just switch to the generated ones.
We need to keep them around so we can inspect them later. We'll also need a
background cleanup every once in a while to free some memory. More on that in
a future commit.
We were just handwaving the partid generation, which broke some tests that
expected the first payment attempt to always have partid=0, so here we just
track the partids assigned in the payment tree, starting at 0.
The status of what started as a simple JSON-RPC call is now spread across an
entire tree of partial payments and payment attempts. So we collect the status
in a single struct in order to report back success of failure.
This is just for testing for now, TLV payload computation will come next. We
stage all the payloads in deserialized form so modifiers can modify them more
easily and serialize them only before actually calling `createonion`.
Te `sendonion` docs where claiming that the `first_hop` needs to specify a
`channel_id` whereas it should really be the `node_id` of the peer we are
trying to contact.
This is necessary so we can build the absolute locktimes in the next step. For
now just fetch the blockheight on each (sub-)payment, later we can reuse the
root blockheight if it ends up using too much traffic.
A payment is considered finished if it is in a final state (success or
failure) or all its sub-payments are finished. If that's the case we notify
`payment_finished` and bubble up through `payment_child_finished`, eventually
bubbling up to the root, which can then report success of failure back to the
RPC command that initiated the whole process.
