This completes the custommsg epic, finally we are back where we began all that
time ago (about 4 hours really...): in a plugin that implements some custom
logic.
This solves a couple of issues with the need to synchronously drop the
connection in case we were required to understand what the peer was talking
about while still allowing users to experiment, just not kill connections.
The number of outputs got updated, but the map used to calculate the
change output's location did not (still assumes only one output). This
patch fixes this to make the output map a variable size.
Changelog-Fixed: JSON API: `txprepare` no longer crashes when more than two outputs are specified
Changelog-Fixed: Detect a previously non-permanent error (`final_cltv_too_soon`) that has been merged into a permanent error (`incorrect_or_unknown_payment_details`), and retry that failure case in `pay`.
This is needed to fully implement handling of blockheight disagreements
between us and payee.
If payee believes the blockheight is higher than ours, then `pay`
should wait for our node to achieve that blockheight.
Changelog-Add: Implement `waitblockheight` to wait for a specific blockheight.
Changelog-Changed: plugin: `notify_sendpay_success` and `notify_sendpay_failure` are now always called, even if there is no command waiting on the result.
We clone the test above, but this time we don't attach waiters (they'd be racy
anyway), and we wait for the notification to be called. This fails, but is
fixed in the next two commits.
Valgrind doesn't really like crashes if compiled without DEVELOPER since that
seems to compile out the debug symbols, resulting in the following error:

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
The optimistic lock prevents multiple instances of c-lightning making
concurrent modifications to the database. That would be unsafe as it messes up
the state in the DB. The optimistic lock is implemented by checking whether a
gated update on the previous value of the `data_version` actually results in
an update. If that's not the case the DB has been changed under our feet.
The lock provides linearizability of DB modifications: if a database is
changed under the feet of a running process that process will `abort()`, which
from a global point of view is as if it had crashed right after the last
successful commit. Any process that also changed the DB must've started
between the last successful commit and the unsuccessful one since otherwise
its counters would not have matched (which would also have aborted that
transaction). So this reduces all the possible timelines to an equivalent
where the first process died, and the second process recovered from the DB.
This is not that interesting for `sqlite3` where we are also protected via the
PID file, but when running on multiple hosts against the same DB, e.g., with
`postgres`, this protection becomes important.
Changelog-Added: DB: Optimistic logging prevents instances from running concurrently against the same database, providing linear consistency to changes.
Some Linux OSs impose a length limit on the path a Unix socket may have. This
is not an issue in `lightningd` since we `chdir()` into that directory before
opening the socket, however in pyln this became a problem for some tests,
since we use absolute paths in the testing framework. It's also a rather
strange quirk to expose to users.
This patch introduces a `UnixSocket` abstraction that attempts to work around
these limitations by aliasing the directory containing the socket into
`/proc/self/fd` and then connecting using that alias.
It was inspired by Open vSwitch code here https://github.com/openvswitch/ovs/blob/master/python/ovs/socket_util.py

We only tested exactly two equal-size payments; indeed, our finalhop
test was backwards. We only complain if the final hop pays more than
twice msat (technically, this test is still too loose for mpp: the
spec says we should sum to the exact amount).

msatoshi was used to indicate the amount the invoice asked for, but

We currently refuse a payment if one is already in flight. For parallel

We were hardcoding the chainparams->chain_hash which caused the query to
return an empty result. By parametrizing the test we can make it work on
elements.
Now "raw_payload" is always the complete string (including realm or length
bytes at the front).
This has several effects:
1. We can receive an decrypt an onion which is grossly malformed.
2. We can still hand this to the htlc_accepted hook.
3. We then fail it unless the htlc_accepted accepts it manually.
4. The createonion API now takes the raw payload, and does not know
anything about "style".
The only caveat is that the sphinx code needs to know the payload
length: we have a call for that, which simply tells it to copy the
entire onion (and treat us as the final node) if it's invalid.

If we can't decode the onion, because the onion got corrupted or we used
`sendonion` without specifying the `shared_secrets` used, the best we can do
is tell the caller instead.
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:

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.

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.

Feerate changes are asymmetric, as they can only be sent by the funder.
For FUNDER, the remote feerate is set when upon send of
commitment_signed, and the local feerate is set on receipt of
revoke_and_ack.
For non-funder, the local feerate is set on receipt of
commitment_signed, and the remote feerate set on send of
revoke_and_ack. In our code, these two happen together.
channeld gets this right, but lightningd ignored the funder/fundee
distinction, and as a result, receipt of a commitment_signed by the
funder altered fees in the database. If there was a reconnection
event or restart, then these (incorrect) values would be used, causing
us to complain about a 'Bad commit_sig signature' and close the
channel.

I had a report of a 0.7.2 user whose node hadn't appeared on 1ml. Their
node_announcement wasn't visible to my node, either.
I suspect this is a consequence of recent version reducing the amount of
gossip they send, as well as large nodes increasingly turning off gossip
altogether from some peers (as we do). We should ignore timestamp filters
for our own channels: the easiest way to do this is to push them out
directly from gossipd (other messages are sent via the store).
We change channeld to wrap the local channel_announcements: previously
we just handed it to gossipd as for any other gossip message we received
from our peer. Now gossipd knows to push it out, as it's local.
This interferes with the logic in tests/test_misc.py::test_htlc_send_timeout
which expects the node_announcement message last, so we generalize
that too.
