This means that c-lightning can now internally decrypt an eventual error
message, and not force the caller to implement the decryption. The main
difficulty was that we now have a new state (channels and nodes not specified,
while shared_secrets are specified) which needed to be handled.
We are breaking with a couple of assumptions, namely that we have the
`path_secrets` to decode the error onion. If this happens we just want it to
error out.
addresses issue #2753.
Formatting the JSON with the default parameters will escape the unicode
symbols in a way that c-lightning won't allow, leading to an exception.
Changelog-Fixed: `pylightning` now handles unicode characters in JSON-RPC requests and responses correctly.
We were using sleeps to hope we catch the password prompt. This makes the test
flaky. So I added a help text followed by a `fflush` to make sure we catcht he
right moment, instead of guessing. The `fflush` is also useful for debugging
if a user ever pipes the output to a file it'd get buffered and the user would
wait forever. The same applies for automated systems such as `expect` or
`pexpect` based scripts that enter the password on prompt.
This will change the command `listconfigs` output in several ways:
- Deprecated the duplicated "plugin" JSON output by replacing it with
- a "plugins" array with substructures for each plugin with:
- path, name and their options
Changelog-Changed: JSON-RPC: `listconfigs` now structures plugins and include their options
Changelog-Deprecated: JSON-RPC: `listconfigs` duplicated "plugin" paths
The spec is (RSN!) going to explicitly denote where each feature should
be presented, so create that infrastructure.
Incorporate the new proposed bolt11 features, which need this.

Do the same thing '--help' does with them; append `...`.

Rounds out the application of `upfront_shutdown_script`, allowing
an accepting node to specify a close_to address.
Prior to this, only the opening node could specify one.
Changelog-Added: Plugins: Allow the 'accepter' to specify an upfront_shutdown_script for a channel via a `close_to` field in the openchannel hook result
This leads to all sorts of problems; in particular it's incredibly
slow (days, weeks!) if bitcoind is a long way back. This also changes
the behaviour of a rescan argument referring to a future block: we will
also refuse to start in that case, which I think is the correct behavior.
We already ignore bitcoind if it goes backwards while we're running.
Also cover a false positive memleak.
Changelog-Fixed: If bitcoind goes backwards (e.g. reindex) refuse to start (unless forced with --rescan).

So far we've only handled legacy payloads, which meant we could drop the realm
byte since it was always 0x00. Once we start handling TLV payloads the first
byte, i.e., the former realm byte, is important since it gives us the length
of the payload. This is a breaking change, however I don't think there's
anyone using the `raw_payload` as of yet.
Changelog-Changed: JSON-RPC: the `raw_payload` now includes the first byte, i.e., the realm byte, of the payload as well. This allows correct decoding of a TLV payload in the plugins.
Spaces just make life a little harder for everyone.
(Plus, fix documentation: it's 'jsonrpc' not 'json' subsystem).

This simplifies our tests, too, since we don't need a magic option to
enable io logging in subdaemons.
Note that test_bad_onion still takes too long, due to a separate minor
bug, so that's marked and left dev-only for now.

1. Printed form is always "[<nodeid>-]<prefix>: <string>"
2. "jcon fd %i" becomes "jsonrpc #%i".
3. "jsonrpc" log is only used once, and is removed.
4. "database" log prefix is use for db accesses.
5. "lightningd(%i)" becomes simply "lightningd" without the pid.
6. The "lightningd_" prefix is stripped from subd log prefixes, and pid removed.

Changelog-changed: Logging: formatting made uniform: [NODEID-]SUBSYSTEM: MESSAGE
Changelog-removed: `lightning_` prefixes removed from subdaemon names, including in listpeers `owner` field.
A log can have a default node_id, which can be overridden on a per-entry
basis. This changes the format of logging, so some tests need rework.

If a 'upfront_shutdown_script' was specified, show the address +

Quite a few of the things in the LightningNode class are tailored to their use
in the c-lightning tests, so I decided to split those customizations out into
a sub-class, and adding one more fixture that just serves the class. This
allows us to override the LightningNode implementation in our own tests, while
still having sane defaults for other users.
Reduce test_feerate_stress iterations, and simply don't run
test_pay_retry under VALGRIND with SLOW_MACHINE at all.

A long time ago (93dcd5fed7), I
simplified the htlc reload code so it adjusted the amounts for HTLCs
in id order. As we presumably allowed them to be added in that order,
this avoided special-casing overflow (which was about to deliberately
be made harder by the new amount_msat code).
Unfortunately, htlc id order is not canonical, since htlc ids are
assigned consecutively in both directions! Concretely, we can have two HTLCs:
HTLC #0 LOCAL->REMOTE: 500,000,000 msat, state RCVD_REMOVE_REVOCATION
HTLC #0 REMOTE->LOCAL: 10,000 msat, state SENT_ADD_COMMIT
On a new remote-funded channel, in which we have 0 balance, these
commits *only* work in this order. Sorting by HTLC ID is not enough!
In fact, we'd have to worry about redemption order as well, as that
matters.
So, regretfully, we offset the balances halfway to UINT64_MAX, then check
they didn't underflow at the end. This loses us this one sanity check,
but that's probably OK.
