The parameter is 'payment_hash' not 'hash', and the 'description' parameter
wasn't documented at all.

And there's a difference between no description and "" as a description:
for no description, listpayments doesn't show the field at all. So fix
that.

We spend quite a bit of time in libsecp256k1 moving them to and from
DER encoding. With a bit of care, we can transfer the raw bytes from
gossipd and manually decode them so a malformed one can't make us
abort().
Before:
real 0m0.629000-0.695000(0.64985+/-0.019)s
After:
real 0m0.359000-0.433000(0.37645+/-0.023)s
At this point, the main issues are 11% of time spent in ccan/io's
backend_wake (I tried using a hash table there, but that actually makes
the small-number-of-fds case slower), and 65% of gossipd's time is
in marshalling the response (all those tal_resize add up!).

It's a very ugly one-liner; really ccan/io should have an io_replan
for this, but it would have to be written carefully as it makes
assumptions currently about plans not changing. In this case, we know
it's in io_write, and we're just moving a pointer.

Such an API is required for when we stream it directly. Almost all our
handlers fit this pattern already, or nearly do.
We remove new_json_result() in favor of explicit json_stream_success()
and json_stream_fail(), but still allowing command_fail() if you just
want a simple all-in-one fail wrapper.

This isn't a big change, since we basically dump the entire JSON
resuly string into the membuf then write it out, but it's prep for the
next changes.

We occasionaly had a travis hang in test_multirpc, and it's due to a
thinko in the prior patch: if a command completes immediately, it will
do the wake before we go to sleep. That means we don't digest the
rest of the buffer until the next write.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
There's a DoS if we keep reading commands and don't insist the client
read the responses.
My initial implementation simply removed the io_duplex, but that
doesn't work if we want to inject notifications in the stream (as we
will eventually want to do), so we operate it as duplex but have each
side wake the other when it's done.

This also highlights the danger of searching the logs: that error
appeared previously in the logs, so we didn't notice that the actual

Some people were alarmed that the state was set to "Loaded from
database" indefinitely. Saying that we are trying to reconnect may be
more informative.
And use wallet_forward_status_in_db() everywhere in db code.
And clean up extra CHANGELOG.md entry (looks like rebase error?)

The left join should make sure we still get the results but
referencing the fields and/or attempting to write them to the JSON-RPC
result will cause unforeseen problems. So just omit if we forgot
something.
Adapts the `test_forward_stats` test to include checks for the
`forwarded_payments` table. Will add checks for the `listforwardings`
RPC call next.

When the wrong key is used, the remote end simply hangs up.
We used to get a random errno, which tends to be "Operation now in progress."
Now it's defined to be 0, detect and provide a better error.

This was from a different series, so I just cherry-picked it.
It adds ccan/membuf as a depenency of ccan/rbuf, though we don't use
it directly yet.

Give a clear error at the beginning if it's not bolt11 payment,
rather than falling foul of other checks.
This will work at least until some altcoin adapts the 'ln' prefix :)

Usually Travis triggers corner cases because it's so slow, but this
time the moons aligned, and it managed to fail test_node_reannounce
because it generated the updated node_announcement with the same
timestamp as the old one.
This is because we only updated "last_announce_timestamp" when
we generated the announcement, not when we got it off the wire or
loaded it from the gossip store.
The fix is to ask the routing code what the latest timestamp is;
we could still generate a clashing timestamp if (1) the gossip store
is lost, and (2) we restart within one second. Hard to care.

Have c-lightning nodes send out the largest value for
`htlc_maximum_msat` that makes sense, ie the lesser of
the peer's max_inflight_htlc value or the total channel
capacity minus the total channel reserve.
While not strictly necessary it's certainly a good idea to test
against the latest one and not encourage users to use old versions.

We initialize it to 30 seconds, but it's *always* overridden by the
gossip_init message (and usually to 60 seconds, so it's doubly
misleading).

Gossipd provided a generic "get endpoints of this scid" and we only
use it in one place: to look up htlc forwards. But lightningd just
assumed that one would be us.
Instead, provide a simpler API which only returns the peer node
if any, and now we handle it much more gracefully.

We don't create unannouncable channels, but other implementations can.
Not only is it rude to expose these via invoices, it's probably not
