The error message "Cannot afford fee" was not exactly correct because
it would also occur if the amount requested could not be afforded. So
I changed it to the more generic "Cannot afford transaction".
Other things:
* Fixed off-by-one satoshi in fundchannel manpage.
* Changed 'arror' to 'error' because we are not pirates.

Someone could try to announce an internal address, and we might probe

This breaks tests, so we add '--dev-allow-localhost' for our tests, so

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
If we're given a wildcard address, we can't announce it like that: we need
to try to turn it into a real address (using guess_address). Then we
use that address. As a side-effect of this cleanup, we only announce
*any* '--addr' if it's routable.
This fix means that our tests have to force '--announce-addr' because
otherwise localhost isn't routable.
This means that gossipd really controls the addresses now, and breaks
them into two arrays: what we bind to, and what we announce. That is
now what we return to the master for json_getinfo(), which prints them
as 'bindings' and 'addresses' respectively.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
1. Add special option where an empty host means 'wildcard for IPv4 and/or IPv6'
which means ':1234' can be used to set only the portnum.
2. Only add this protocol wildcard if --autolisten=1 (default)
and no other addresses specified.
3. Pass it down to gossipd, so it can handle errors correctly: in most cases,
it's fatal not to be able to bind to a port, but for this case, it's OK
if we can only bind to one of IPv4/v6 (fatal iff neither).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
It's become clear that our network options are insufficient, with the coming
addition of Tor and unix domain support.
Currently:
1. We always bind to local IPv4 and IPv6 sockets, unless --port=0, --offline,
or any address is specified explicitly. If they're routable, we announce.
2. --addr is used to announce, but not to control binding.
After this change:
1. --port is deprecated.
2. --addr controls what we bind to and announce.
3. --bind-addr/--announce-addr can be used to control one and not the other.
4. Unless --autolisten=0, we add local IPv4 & IPv6 port 9735 (and announce if they are routable).
5. --offline still overrides listening (though announcing is still the same).
This means we can bind to as many ports/interfaces as we want, and for
special effects we can announce different things (eg. we're sitting
behind a port forward or a proxy).
What remains to implement is semi-automatic binding: we should be able
to say '--addr=0.0.0.0:9999' and have the address resolve at bind
time, or even '--addr=0.0.0.0:0' and have the port autoresolve too
(you could determine what it was from 'lightning-cli getinfo'.

When we get a reconnection, kill the current remote peer, and wait for the
master to tell us it's dead. Then we hand it the new peer.
Previously, we would end up with gossipd holding multiple peers, and
the logging was really hard to interpret; I'm not completely convinced
that we did the right thing when one terminated, either.
Note that this now means we can have peers with neither ->local nor ->remote
populated, so we check that more carefully.

1. Lifetime of 'struct reaching' now only while we're actively doing connect.
2. Always free after a single attempt: if it's an important peer, retry
on a timer.
3. Have a single response message to master, rather than relying on
peer_connected on success and other msgs on failure.
4. If we are actively connecting and we get another command for the same
id, just increment the counter
The result is much simpler in the master daemon, and much nicer for
reconnection: if they say to connect they get an immediate response,
rather than waiting for 10 retries. Even if it's an important peer,
it fires off another reconnect attempt, unless it's actively
connecting now.
This removes exponential backoff: that's restored in next patch. It
also doesn't handle multiple addresses for a single peer.

Got some intermittant failures, mainly caused by the tests being slow
enough that the peer reconnected. We should always suppress

We should turn off dev-no-reconnect *always* unless told we will
reconnect, and since we can't if !DEVELOPER, don't do the connection
check there.
Instead of adding an option to line_graph, we remove it in favor
of connect (since we only use it with n=2 anyway).

I had a weird failure which was caused by an unexpected disconnect and

Since we seem to have some isolation concerns when re-generating the
same HSM secret and re-parsing the blockchain some blocks in the past.
This also alleviates the problem of printing to a logging stream that
has been closed. Previously bitcoind would keep running despite a test
had failed and continue logging to the, now closed, StringIO that
py.test uses when capturing stdout.
The performance impact seems to be 1-3 second per test, not too bad
IMHO for increased test isolation and cleaner logs:

All peers come from gossipd, and maintain an fd to talk to it. Sometimes
we hand the peer back, but to avoid a race, we always recreated it.
The race was that a daemon closed the gossip_fd, which made gossipd
forget the peer, then master handed the peer back to gossipd. We stop
the race by never closing the gossipfd, but hand it back to gossipd
for closing.
Now gossipd has to accept two fds, but the handling of peers is far
clearer.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Now the flow is much simpler from a lightningd POV:
1. If we want to connect to a peer, just send gossipd `gossipctl_reach_peer`.
2. Every new peer, gossipd hands up to lightningd, with global/local features
and the peer fd and a gossip fd using `gossip_peer_connected`
3. If lightningd doesn't want it, it just hands the peerfd and global/local
features back to gossipd using `gossipctl_handle_peer`
4. If a peer sends a non-gossip msg (eg `open_channel`) the gossipd sends
it up using `gossip_peer_nongossip`.
5. If lightningd wants to fund a channel, it simply calls `release_channel`.
Notes:
* There's no more "unique_id": we use the peer id.
* For the moment, we don't ask gossipd when we're told to list peers, so
connected peers without a channel don't appear in the JSON getpeers API.
* We add a `gossipctl_peer_addrhint` for the moment, so you can connect to
a specific ip/port, but using other sources is a TODO.
* We now (correctly) only give up on reaching a peer after we exchange init
messages, which changes the test_disconnect case.

data, but when the dev_disconnect file is truncated (a hacky, but

There are three special format specifiers that can be used in the

%p is replaced with the current process ID. This is very useful for
program that invoke multiple processes. WARNING: If you use
--trace-children=yes and your program invokes multiple processes OR
your program forks without calling exec afterwards, and you don't
use this specifier (or the %q specifier below), the Valgrind output
from all those processes will go into one file, possibly jumbled
up, and possibly incomplete.

Running long integration tests could result in `bitcoind` dropping the
connection inbetween calls, and since python-bitcoinlib does not
reconnect and/or retry, all subsequent tests would fail as well. This
patch switches to throwaway connections, each serving just one
request. It's easier than to reach into the bitcoinlib to reconnect
and reauth, but comes with some overhead, but I think it's acceptable
for the few bitcoin calls we actually perform.
By looking for 'Done loading' in the log output we should actually be
called after `SetRPCWarmupFinished` in bitcoind. Only then is it safe
to make RPC calls. This resulted in the test suite being a bit flaky.
