pytest captures the output by monkey patching out `sys.stdout`. This may
conflict with our use of `sys.stdout` when configuring logging, resulting in
the "Write to closed file" issue that is spamming the logs. By making the
logging configuration a fixture hopefully we always use the correct
stdout (after pytest has monkey-patched it).
Some tests may not spawn a node at all, so make sure that our assumption that
the directory exists in the fixture cleanup is correct by creating the
directory.
a few things. one is that `is_in_log` returns a result rather than
enforcing a condition. so these lines all need asserts
two is that with the 'allow_deprecated_apis' option on, the python json
parser overwrites the now typed input with the later-added string
version, so the only option value present in the option key-value set is
the last, string one. the check for this has been updated to only verify
that the string version is included (i manually verified that both are
printed to the JSON message)
We were nesting like the following:
```json
{"params": {
"rpc_command": {
"rpc_command": {
}
}
}
```
This is really excessive, so we unwrap once, and now have the following:
```json
{"params": {
"rpc_command": {
}
}
```
Still more wrapping than necessary (the method is repeated in the `params`
object), but it's getting closer.

Before this patch we would only update `channel->last_tx` with the newly
proposed closure tx from the peer if the fee of the new one was lower.
In negotiations where we are at the higher end and the peer starts
lower, all peer's subsequent proposals will be higher than his initial
proposal and in this case we would never update `channel->last_tx`
and would wrongly broadcast his initial proposal at the end of the
negotiation.
Fixes https://github.com/ElementsProject/lightning/issues/3549
Changelog-Fixed: Always broadcast the latest close transaction at the end of the close fee negotiation, instead of sometimes broadcasting the peer's initial closing proposal.
We are returning a `BADONION` error despite the cause being an invalid onion
payload containing an unknown even TLV type. It really should return
`INVALID_ONION_PAYLOAD` errors instead.
ChangeLog-Added: New `getsharedsecret` command, which lets you compute a shared secret with this node knowing only a public point. This implements the BOLT standard of hashing the ECDH point, and is incompatible with ECIES.
Instead of saving a stripped_update, we use the new
local_fail_in_htlc_needs_update.
One minor change: we return the more correct
towire_temporary_channel_failure when the node is still syncing.

For bitcoind_fail_first:
We only ever send `getblock` if we got a successful block hash from
`getblockhash`, and if we can't get the block in that case it means
our Bitcoin backend is faulty and we shouldnt continue.
So, mock `getblockhash` instead, which is authorized to spuriously fail.
For both bitcoind_fail_first and bitcoind_failure:
Adapt the logs.
Add new check if we're funder trying to add HTLC, keeping us
with enough extra funds to pay for another HTLC the peer might add.
We also need to adjust the spendable_msat calculation, and update
various tests which try to unbalance channels. We eliminate
the now-redundant test_channel_drainage entirely.
Changelog-Fixed: Corner case where channel could become unusable (https://github.com/lightningnetwork/lightning-rfc/issues/728)

Make the `htlc_accepted` hook the first chained hook in our repertoire. The
plugins are called one after the other in order until we have no more plugins
or the HTLC was handled by one of the plugins. If no plugins handles the HTLC
we continue to handle it internally like always.
Handling in this case means the plugin returns either `{"result": "resolve",
...}` or `{"result": "fail", ...}`.
Changelog-Changed: plugin: Multiple plugins can now register for the htlc_accepted hook.
This is the last venue we need to add custom featurebits to, so we also unmark
the test as xfail.
Changelog-Added: plugin: Plugins can now signal support for experimental protocol extensions by registering featurebits for `node_announcement`s, the connection handshake, and for invoices. For now this is limited to non-dynamic plugins only
restrict fundchannel_cancel usage to only the opener side
Changelog-Changed: Only the opener of a fundchannel can cancel the channel open with fundchannel_cancel
As a separated commit because it was pre-existent (changelog + xfail test).
This also fix a logical problem in lightningd/plugin_control: we were
assuming a plugin started with 'plugin start' but which did not comport
a 'dynamic' entry in its manifest to be dynamic, though it should have
been treated as static.
Changelog-fixed: plugins: Dynamic C plugins can now be managed when lightningd is up
