While loading HTLCs from the database we might not yet have all the
incoming HTLCs loaded when loading a dependent htlc_out. So we defer
the wiring of the HTLCs until we are sure we have them loaded.
This is also the first step towards keeping that association only in
the database, since otherwise we cannot selectively load channels from
DB.

Also added a small warning to one of the used enums not to reorder or
insert values. They'd break the update path.

Especially when testing we might want to disable the automatic
reconnection logic in order not to masquerade bugs that disappear when
reconnecting.

This broke somewhere in the recent changes, because we override
TailalbleProc stop(). Break out log extractor.

We don't hit this in testing, since we wait for startup already. Hacking
tests to avoid that, I tested this code by hand.

Moved the flagging for allowed failures into the factory getter, and
renamed into `may_fail`. Also stopped the teardown of a node from
throwing an exception if we are allowed to exit non-cleanly.

A failed returncode check could result in the cleanup for other
lightningds to be skipped. Now make sure to cleanup all and then
rethrow an exception that contains all returncodes.

We used to simply kill the daemon, which in some cases could result in
half-written crashlogs and similar artifacts such as half-completed
RPC calls. Now we ask lightningd to stop nicely, give it some time and
only then kill it. We also return the returncode of the daemon.

Using pc after free in the pay_command_destroyed destructor, so
we just steal cmd onto pc so free order is the one we want.

So far only happens during normal shutdown, but it may happen in other
cases as well. We simply define a new destructor that unregisters the
`cmd` from the `jcon`.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
These were fun to hunt down. The jcon and the conn are allocated off
of ld, so the free order is unspecified and if conn is freed before
conn then the finish_jcon destructor uses conn after free.
[ Edit: split commit, modified to use a destructor directly on jcon,
which is more robust than relying on it only being freed via conn --RR ]

peer_fail_permanent() frees peer->owner, but for bad_peer() we're
being called by the sd->badpeercb(), which then goes on to
io_close(conn) which is a child of sd.
We need to detach the two for this case, so neither tries to free the
other.
This leads to a corner case when the subd exits after the peer is gone:
subd->peer is NULL, so we have to handle that too.

Note that it should really be a flag to daemon on construction, too,
but that may interfere with another concurrent branch so I've deferred.

We have a race where we start onchaind, but state is unchanged, so checks
like peer_control.c's:
peer_ready = (peer->owner && peer->state == CHANNELD_AWAITING_LOCKIN);
if (!peer_ready) {
log_unusual(peer->log,
"Funding tx confirmed, but peer state %s %s",
peer_state_name(peer->state),
peer->owner ? peer->owner->name : "unowned");
} else {
subd_send_msg(peer->owner,
take(towire_channel_funding_locked(peer,
peer->scid)));
}
Can send to the wrong daemon.

We were sending a channeld message to onchaind, which was v. confusing
due to overlap. We make all the numbers distinct, which means we can
also add an assert() that it's valid for that daemon, which catches
such errors immediately.

GCC optimizes it out anyway: I sent an uninitialized var and it sent 8!
The receiver checks the value is 0 or 1 anyway.

We re-use the value for reasonable_depth given by the master, and we
tell it when our timeout transactions reach that depth.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
In the next test, we wait for multiple 'sendrawtx exit 0' which
doesn't work because we use a set not a list, and the current code
would match multiple against the same thing. The result was we didn't
wait for the final sendrawtransaction, and occasionally had test
failures as a result.
