This resolves the problem where both channeld and gossipd can generate
updates, and they can have the same timestamp. gossipd is always able
to generate them, so can ensure timestamp moves forward.

Instead of considering it a temporary step, consider it a necessary preamble
to sending updates.
This means (in the next patch) when we tell gossipd to generate the updates,
it's always done after we've told it to create the channel.

We can restore them once we get parallel testing on Travis, but meanwhile
we time out because of the 30 seconds bitcoind poll.

Because we have too many which are never used and I don't want to document
them.
1. Remove unused anchor_onchain_wait. When implemented, it should be
hardcoded to 100 or more.
2. Remove anchor_confirms_max. 10 always reasonable, and we can readd
an override option should someone need it.
3. max_htlc_expiry should be the same as locktime_max (which increases
from 3 to 5 days by default): they're both a limit on how long
funds can be locked up.
4. channel_update_interval should always be a dev option.

Make --override-fee-rates a dev option. We use default-fee-rate in
its place, which (since bitcoind won't give fee estimates in regtest
mode for short chains) gives an effective feerate of 15000/7500/3750.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We never hit the guess_feerate() path, because we turned a 0 ("can't
estimate fee") into 253.
This also revealed that we weren't initializing topo->feerate, and
that we were giving spurious updates even if we were using override-fee-rates.

We erroneously create updates with the same timestamps when tests run
quickly, and the second one is ignored.
We've already noted that this should be fixed: gossipd should generate
all the updates, as it already has to do the case where channeld
crashed, for example. But that's a bigger change.

If we hit depth 6, we would start exchanging announcement signatures.
However, we should still send a temporary update while waiting for the
reply; make the logic clear in this case that we should always send
one or the other.

The condition in send_channel_update is wrong: it needs to match the
conditions under which we send announcements.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
@cdecker points out that in test_forward, where we manually create a route,
we get an error back which contains an update for an unknown channel.
We should still note this, but it's not an error for testing.

This is something which generally shouldn't happen, but we didn't
notice it previously.
We ignore this warning in the case where a channel was deleted: this
happens because one side can send an update while the other notices
that the channel is closed.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Note: this will break the gossip_store if they have current channels,
but it will fail to parse and be discarded.
Have local_add_channel do just that: the update is logically separate
and can be sent separately.
This removes the ugly 'bool add_to_store' flag.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We always call:
send_temporary_announcement(peer);
send_announcement_signatures(peer);
We should handle these in one place, since the conditional at the top
of them actually makes sure only one is effective. We also make the
caller set the peer->have_sigs[LOCAL] flag, instead of doing it
inside send_announcement_signatures().
We were sending announcements at the wrong time (on restart) somtimes.
We also move announce_channel() into the same logic, so it's always
together.

Just have a "new depth" callback, and let channeld do the right thing.
This makes the channeld paths a bit more straightforward.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Some paths (eg reconnect) were unconditionally sending a channel_update.
valgrind wasn't catching it because we unmarshal short_channel_ids[LOCAL]
as all-zeroes, so it's technically "initialized".
Create a wrapper to do this, and change the 'bool disabled' flag to be
the explicit disable flag value for clarity.

Setting these options could fail the `pytest` target if `pytest-test-groups` is

1. We need to test all bits, not all bytes.
2. Both local and global features need to be supported.
3. Untested code is broken code.

Tor wasn't actually working for me to connect to anything, but it worked
for 'ssh -D' testing.
Note that the resulting 'netaddr' is a bit weird, but I guess it's honest.

Good for debugging (you have to send SIGUSR1 to lightning_gossipd to turn
it on though, and --log-level=io on the lightningd cmdline to have it
output IO messages by default).
I also noticed that io_tor_connect_after_req_host() does a useless
test on reach->buffer[0] after it's *written*: remove it.

Use a wireaddr_internal directly (which is what we want).
Also, don't hardcode 9735, use DEFAULT_PORT internally in
seed_resolve_addr().
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Previously it converted the wireaddr to a string internally: to support
unresolved names we need that done externally.
We actually tell the SOCKS5 proxy to do a domain lookup already, even
though we give use IP/IPv6 address, so this change is sufficient to
support connect-by-name.
Note replacement of assert() with an explicit case statement, which
has the benefit that the compiler complains when we add new
ADDR_INTERNAL types.
