I run with ulimit -c unlimited, and valgrind leaves core files like
valgrind-errors.22114.core.22114 which test_lightning.py tries to
parse as log files.

It crashes under valgrind, causing a valgrind error: valgrind gives us a
backtrace anyway, so we don't need it.

We're going to need this, and the PRINTF_FMT(1,2) in front of it caused
mockup.sh to miss the declaration.
We also eliminate the obviously-unused fallback case (which referred

Normally, we get an error as soon as we send WIRE_REVOKE_AND_ACK. But if the
commit timer goes off, we get some extra cycles, during which the other side
can reconnect. In this case, we simply kill the channeld before it fails,
and never check for the permfail string.

We need to derive this from the fd when they connect in, but we already
know it if we're connecting out.
We want this so we can tell (in next few patches) master the peer's address.

954a3990fa had two errors:
1) We created the handoff message *before* we sent the final packet, meaning
that the cryptostate was out-of-sync.
2) We called io_wait() on the output side of a duplex connection: it has
to be io_wait_out().
This time, stress testing for 2 hours revealed no more problems.

There are others, but they really are casued by bad failure. We need a

This is a bit messier than I'd like, but we want to clearly remove all
dev code (not just have it uncalled), so we remove fields and functions
altogether rather than stub them out. This means we put #ifdefs in callers
in some places, but at least it's explicit.
We still run tests, but only a subset, and we run with NO_VALGRIND under
Travis to avoid increasing test times too much.

In this case, it was a gossip message half-sent, when we asked the peer
to be released. Fix the problem in general by making send_peer_with_fds()
wait until after the next packet.

There is a race we see sometimes under valgrind on Travis which shows
gossipd receiving the node_announce from master before it reads the
channel_announce from channeld, and thus fails. The simplest solution
is to send the channel_announce and channel_update to master as well,
so it can ensure it sends them to gossipd in order

It makes it impossible to embed an ipaddr in another structure, since we
always try to skip over any zeroes, which may swallow a following field.
Do the skip specially for the case where we're parsing routing messages:
we never use padding for our own internal messages anyway.

Makes it easier to compare before/after failures. Ideally, we should
run under Travis both with this option and with the seed based on the
entire tmp path (which is still reproducible with determination, but
not fixed every run like this is).

There are now only two kinds of subdaemons: global ones (hsmd, gossipd) and
per-peer ones. We can handle many callbacks internally now.
We can have a handler to set a new peer owner, and automatically do
the cleanup of the old one if necessary, since we now know which ones
are per-peer.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We currently rely on a zero exit status. That's the only difference between
onchain finished handling and other per-peer daemons, so instead we should
have an explicit "done" message. This is both clearer, and allows us to
unify.
