It introduces imprecision (took 1 satoshi off results in the coming
tests), and we have a helper for this already.

This was suggested via mail: the SHA256 sums should be extracted from the
sha256sums file we are checking against, which also allows us to switch bitcoind
version at build time.

We only did this when we were first creating a wallet, or when we
asked for a relative rescan, not in the normal case!

Lightning charge tests stopped working without a timeout, being unable
to find a route. The 15 second delay doesn't matter in real life, but
in these scenarios it does. This fixes it by making sure the channel
is usable immediately.

We got an index error, because status had only one field (onchaind not
started yet).

Normal wallet txs get reconfirmed as blocks come in, but ones which need
closeinfo are more fragile, so we do it manually using txwatch for them.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We're about to use the txwatch facility for UTXOs, where there's no channel,
so allow that the be NULL, and hand the struct lightningd which callers
want anyway.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Note that we don't actually need the output number: it's the tx itself
which is confirmed. And the next caller doesn't have it convenient, so
eliminate it.

These are not confirmed by the normal methods (wallet_can_spend is false!),
so we'll deal with them manually.
We use UTXO_FIELDS in wallet_add_utxo, too, for consistency.

In one case, the channel_update which we expected to activate the channel
from l2 was suppressed as redundant. This is certainly valid, so just
check the results.

This was a very simple change and allowed us to remove the special
`json_opt_tok` macro.
Moved the callback out of `common/json.c` to `lightningd/json.c` because the new
callbacks are dependent on `struct command` etc.
(I already started on `json_tok_number`)
My plan is to:
1. upgrade json_tok_X one a time, maybe a PR for each one.
2. When done, rename macros (i.e, remove "_tal").
3. Remove all vestiges of the old callbacks
4. Add new callbacks so that we no longer need json_tok_tok!
(e.g., json_tok_label, json_tok_str, json_tok_msat)

Waiting for three node_announcments isn't always enough, since l2 can
publish two of them (an independent bug). Do the more Right Thing and
just wait for 30 seconds of no input...

1. connect convenience variable for improved readabilty.
2. a comment explaining that timer is on channel, not HTLC.
3. use modern python style in test_htlc_send_timeout

Now sending a ping makes sense: it should force the other end to send
a reply, unblocking the commitment process.
Note that rather than waiting for a reply, we're actually spinning on
a 100ms loop in this case. But it's simple and it works.

This doesn't do much (though we might get an error before we send the
commitment_signed), but it's infrastructure for the next patch.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Currently, if we don't realize a TCP connection is down, we almost
certainly don't find out until *after* we're sent the
commitment_signed message, in which case we cannot fail the incoming
HTLC.
This test demonstrates that. Note the 30 second sleep: we should really
run Travis tests in parallel!

Avoid that 200ms loss. We don't want to disable nagle generally,
since it's great for gossip and other traffic; we just want to push at
critical times.

Since we now fixed the bug where nodes receiving a connection would
try to reconnect to the source IP/port of that connection, we now expose
an issue mentioned by other implementers: we can continually cross over
reconnections unless we add some fuzz. One second should be sufficient.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
If we have an address hint, we start with that, but we'll use
node_announcement information if required.
Note: we (ab)use the address hint when restoring from the database
or reconnecting, even if the connection was *incoming*. That meant
that the recipient of a connection would *never* manage to connect out.
We still don't take multiple addresses from the DNS seeds: I assume we
should, since there could be IPv4 and IPv6.
