Changelog-changed: .lightningd plugins and files moved into <network>/ subdir
Changelog-changed: WARNING: If you don't have a config file, you now may need to specify the network to lightning-cli

This lets you have a default, but also a network-specific config.

Changelog-changed: Options: `config` and <network>/`config` read by default.
This leads to all sorts of problems; in particular it's incredibly
slow (days, weeks!) if bitcoind is a long way back. This also changes
the behaviour of a rescan argument referring to a future block: we will
also refuse to start in that case, which I think is the correct behavior.
We already ignore bitcoind if it goes backwards while we're running.
Also cover a false positive memleak.
Changelog-Fixed: If bitcoind goes backwards (e.g. reindex) refuse to start (unless forced with --rescan).

Spaces just make life a little harder for everyone.
(Plus, fix documentation: it's 'jsonrpc' not 'json' subsystem).

We can definitely get a pong from l1 (should test be slow enough):
it's l3 we are concerned about.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This simplifies our tests, too, since we don't need a magic option to
enable io logging in subdaemons.
Note that test_bad_onion still takes too long, due to a separate minor
bug, so that's marked and left dev-only for now.

1. Printed form is always "[<nodeid>-]<prefix>: <string>"
2. "jcon fd %i" becomes "jsonrpc #%i".
3. "jsonrpc" log is only used once, and is removed.
4. "database" log prefix is use for db accesses.
5. "lightningd(%i)" becomes simply "lightningd" without the pid.
6. The "lightningd_" prefix is stripped from subd log prefixes, and pid removed.

Changelog-changed: Logging: formatting made uniform: [NODEID-]SUBSYSTEM: MESSAGE
Changelog-removed: `lightning_` prefixes removed from subdaemon names, including in listpeers `owner` field.
A log can have a default node_id, which can be overridden on a per-entry
basis. This changes the format of logging, so some tests need rework.

*If* we know the key has signed something else (as is the case for
channel_announcement) then we can effectively trust the key derivation.
This matches how LND's VerifyMessage works, though in the next patch
we will document it exactly.

Thanks Twitter helpers @duck1123 and @jochemin for tests!
And @bitconner for the initial test vector.

I had a report of a 0.7.2 user whose node hadn't appeared on 1ml. Their
node_announcement wasn't visible to my node, either.
I suspect this is a consequence of recent version reducing the amount of
gossip they send, as well as large nodes increasingly turning off gossip
altogether from some peers (as we do). We should ignore timestamp filters
for our own channels: the easiest way to do this is to push them out
directly from gossipd (other messages are sent via the store).
We change channeld to wrap the local channel_announcements: previously
we just handed it to gossipd as for any other gossip message we received
from our peer. Now gossipd knows to push it out, as it's local.
This interferes with the logic in tests/test_misc.py::test_htlc_send_timeout
which expects the node_announcement message last, so we generalize
that too.

Since elements addresses look quite different from the bitcoin mainnet
addresses I just added a sample to the chainparams fixture. In addition I
extracted some of the fixed strings to reference chainparams instead.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
We were checking against hardcoded hrp and prefixes. Now we parametrize via
the chainparams.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
We are checking against chain-dependent constants, so let's make sure we are
using the ones for the correct chain.

It only had an effect if the peer didn't support option_gossip_queries, but
still, we don't want a gossip blast any more.

We will soon have a postgres backend as well, so we need a way to control the
postgres process and to provision DBs to the nodes. The two interfaces are the
dsn that we pass to the node, and the python query interface needed to query
from tests.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
It's generally clearer to have simple hardcoded numbers with an
#if DEVELOPER around it, than apparent variables which aren't, really.
Interestingly, our pruning test was always kinda broken: we have to pass
two cycles, since l2 will refresh the channel once to avoid pruning.
Do the more obvious thing, and cut the network in half and check that
l1 and l3 time out.

In this one, we always send my_current_per_commitment_point, though it's

This is an issue that was raised in #2665: some of the dependencies where
causing warnings to be added to the logs about deprecated dependencies. Since
I did not get these warnings I just blanket updated all the dependencies in
the hopes of getting the warnings to resolve.

This is probably worth preventing.
1. Our depth estimate would be inaccurate possibly leading to us
timing out too early.
2. If we're not up-to-date our onchain funds are unknown.
3. We wouldn't be able to send or receive HTLCs until we're synced anyway.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We want to still allow incoming connections, and reestablishment of
channels, but if one tries to give us an HTLC, stall until we're
synced.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
If we don't know block height, we shouldn't be sending HTLCs. This
stops us forwarding HTLCs as well as new payments.

@renepickhardt has a shell script we broke. While we still produce
perfectly valid JSON, we should not gratuitously change tool output.
Plus, I prefer the missing space before the ':'.

Dumb programs which have a --daemon option call fork() early. This is
terrible UX since startup errors get lost: the program exits with
"success" immediately then you discover via the logs that it didn't
start at all.
However, forking late introduced a heap of problems with changing
pids. Instead, fork early but keep stderr and the parent around: if
we fail early on, the parent fails with us. We release our parent
with an explicit action just before the main loop.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We create our children then fork, so we're not a parent. I noticed this
because 'lightning-cli stop' takes a long time: this is because it tries to
wait for them and they don't respond.

Our previous param support was a bit limited in this case.
We create a dev- command multiplexer, so we can exercise it.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
And clean up some dev ones which actually happen (mainly by calling
channel_fail_permanent which logs UNUSUAL, rather than
channel_internal_error which logs BROKEN).
