The old value of 1000 sat was too small to cover the dust reserves.
This lead to the situation when trying to open a channel with minimal
amount, the channels got refused because they were not able cover the
commitment fees.
For this reason the minimal capacity should be increased to i.e. 10k
satoshi, as the technical minimum that also accounts for fees and
reserves is somewhere around 6k sat.
Refactored the weighted-reservoir-sampling algo to make it more straightforward.
It now uses the excess as fraction of capacity as weight. This favors channels that
are more _relatively_ unbalanced to be used for incoming payment.
Now passes test_invoice_routeboost_private() when using max fundamount=16777215.
make it a bit easier to track mutual channel closures by
adding broadcast txid to the listpeers billboard.
since lightningd manages the 'identity' of the closing tx we need
to send it back to closingd so it can update the billboard
appropriately.
We're going to make it async, so start by moving the core code into
invoice.c and having that directly call fail/success functions for the
htlc.
We add an extra check in fulfill_htlc() that the HTLC state is correct:
that can't happen now, but may once we're async.

This is currently done higher up, in handle_channel_update(), but
that's one reason why handle_channel_update() has to do a channel
lookup. Moving the check down means handle_channel_update() can do a
minimal "get node id for this channel" so it can check the signature.
This helps, because the chan lookup semantics are changing in the next
few patches.

The user can explicitly create such things (within [] or ") as we paste
those cases literally, but not for the simple cases.

Plugins don't do it right anyway, and we're about to remove it from
lightningd. Produces same format as json_pp.

They don't clean up after themselves, so best we do it here (by this
point we've already done the pid check to make sure we're the only
lightningd here anyway).

In particular, the assert when `--addr=/sockname` is used, and that it
doesn't clean up on restart, requiring manual deletion of the socket.

1. We need to read in as a byte string, then decode into utf8 once we
have a marker. Otherwise we seem to mangle it horribly, and we
might have a bad utf8 string anyway.
2. We need to suppress the JSON \u escapes on output.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We should be able to pass UTF-8 strings to and from plugins without
python turning them into JSON-\u escapes.

Rather than using LightningJSONDecoder's implicit "field name and
value ends in msat, try converting to Millisatoshi", we do it to
parameters using type annotations.
If you had a parameter which was an array or dict itself, we don't
delve into that, but that's probably OK.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We don't, but we should, like we do for normal RPC. However, I chose
to use function annotations, rather than names-ending-in-'msat'
because it's more Pythony.

New name is less confusing, and most people should be transitioning to

This is the same deprecation, but one level up. For the moment, we
still support invoices with a `h` field (where description will be
necessary) but that will be removed once this option is removed.
Note that I just changed pylightning without backwards compatibility,
since the field was unlikely to be used, but we could do something
more complex here?

In particular this matches the case of `their_unilateral/to_us` outputs, which
were missing their addresses so far.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
We want to disallow using unconfirmed outputs by default, so making the
default 1 confirmation seems a good idea. This also matches `bitcoind`s
minimum confirmation requirement.
Arming however breaks some of our tests, so I used `minconf=0` for the
breaking tests and added a new test specifically for the `minconf` parameter
for `fundchannel`.

An uncommitted channel should not keep the peer in the db, since the
uncommitted channel isn't in the db itself.

This is particularly interesting because we handle overflow during route
calculation now; this could happen in theory once we wumbo.
It fixes a thinko when we print out routehints, too: we want to print
them out literally, not print out the effect they have on fees (which
is in the route, which we also print).
This ABI change doesn't need a CHANGELOG, since paystatus is new since
release.

Little point having users handle the postfixes manually, this
translates them, and also allows Millisatoshi to be used wherever an
'int' would be previously.
There are also helpers to create the formatting in a way c-lightning's
JSONRPC will accept.
All standard arithmetic operations with integers work.

We had occasional failures, because the fuzz could overwhelm the difference
in routes. Increasing the amount to 2,000,000 millisatoshis makes the
riskfactor 53msat (2000000 * 14 * 10 / 5259600) which is always greater
than the worst-case fuzz of 5% on the fee of 1002msat.
