Christian Decker 86d4362b65 wallet: Don't delete channels from DB, mark them closed.
Since we now have a couple of long-lived dependents it is time we stop
removing channels from the table once they are fully closed, and instead just
mark them as closed. This allows us to keep forwards and transactions foreign
keys intact, and it may help us debug things after the fact.

Fixes #2028

Rusty Russell 220449e1cd ccan: import ccan/json_out and ccan/json_escape.
These are generalized from our internal implementations.

The main difference is that 'struct json_escaped' is now 'struct
json_escape', so we replace that immediately.

The difference between lightningd's json-writing ringbuffer and the
more generic ccan/json_out is that the latter has a better API and
handles escaping transparently if something slips through (though
it does offer direct accessors so you can mess things up yourself!).

Rusty Russell 919f390a93 sendpay: rename 'description' to 'label'.
This field was used by `pay` to hold the bolt11 description if the bolt11
string used `h` to hash the description (which nobody ever did).  If the
`h` field wasn't present, it could contain anything, as it wasn't checked.

It's really useful to have a label for payments (eg. '1 Cuban'), but adding
yet-another option would be painful, so we simply rename 'description'
to 'label' except inside the db.

This means we need to do some tricky parameter parsing to handle array
and keyword JSON arguments, but only until we remove the old name.

Since '=' isn't a sequence point, the compiler can (and does!) cache

due to tal_resize().

The new version is somewhat less convenient to use, but doesn't have

This seems like a premature optimization: it tried to cut down the number of

missing field that was set by the previous iteration.

Rusty Russell fed5a117e7 Update ccan/structeq.
structeq() is too dangerous: if a structure has padding, it can fail
silently.

The new ccan/structeq instead provides a macro to define foo_eq(),
which does the right thing in case of padding (which none of our
structures currently have anyway).

Upgrade ccan, and use it everywhere.  Except run-peer-wire.c, which
is only testing code and can use raw memcmp(): valgrind will tell us
if padding exists.

Interestingly, we still declared short_channel_id_eq, even though
we didn't define it any more!

Rusty Russell 5a0bc83b20 Tor: don't do seed queries if we're supposed to always use proxy.
Risks leakage.  We could do lookup via the proxy, but that's a TODO.

There's only one occurance of getaddrinfo (and no gethostbyname), so
we add a flag to the callers.

Note: the use of --always-use-proxy suppresses *all* DNS lookups, even
those from connect commands and the command line.

FIXME: An implicit setting of use_proxy_always is done in gossipd if it
determines that we are announcing nothing but Tor addresses, but that
does *not* suppress 'connect'.

This is fixed in a later patch.

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).

Rusty Russell 73cd009a4c gossipd/lightningd: use wireaddr_internal.
This replacement is a little menial, but it explicitly catches all
the places where we allow a local socket.  The actual implementation of
opening a AF_UNIX socket is almost hidden in the patch.

The detection of "valid address" is now more complex:

	p->addr.itype != ADDR_INTERNAL_WIREADDR || p->addr.u.wireaddr.type != ADDR_TYPE_PADDING

But most places we do this, we should audit: I'm pretty sure we can't
get an invalid address any more from gossipd (they may be in db, but
we should fix that too).

Rusty Russell be1f33b265 gossipd: have master explicitly tell us when peer is disconnected.
Currently we intuit it from the fd being closed, but that may happen out
of order with when the master thinks it's dead.

So now if the gossip fd closes we just ignore it, and we'll get a
notification from the master when the peer is disconnected.

The notification is slightly ugly in that we have to disable it for
a channel when we manually hand the channel back to gossipd.

Note: as stands, this is racy with reconnects.  See the next patch.

Rusty Russell 86a04c59d4 lightningd: maintain a status billboard for each channel.
Each state (effectively, each daemon) has two slots: a permanent slot
if something permanent happens (usually, a failure), and a transient
slot which summarizes what's happening right now.

Uncommitted channels only have a transient slot, by their very nature.

Now any struct channel is a genuine channel, the following fields are

2. our_msatoshi: doesn't need to be a pointer.
3. last_sig: doesn't need to be a pointer.
4. channel_info: doesn't need to be a pointer.

Rusty Russell 72108f0cb9 wallet: don't use rowid for the channel's DBID.
We derive the seed from this, so it needs to be unique, but using
rowid forced us to put the channel into the db early, before it
was ready.

Instead, use a counter to ensure uniqueness, initialized when we load
existing peers.  This doesn't need to touch the database at all.

As we now have only two places where the channel is committed (the
funder and fundee paths), so we create a new explicit
'wallet_channel_insert()' function: 'wallet_channel_save()' now just
updates.

Note that this also fixes some weirdness in
wallet_channels_load_active: we strangely avoided loading channels in
CLOSINGD_COMPLETE (which fortunately was a transient state, so
unlikely anyone hit this).  Note that since the lines above already
delete all the OPENINGD channels, we now simply load them all.

Rusty Russell 55d962046b Rename (almost) all destructors to destroy_<type>.
We usually did this, but sometimes they were named after what they did,
rather than what they cleaned up.

There are still a few exceptions:
1. I didn't bother creating destroy_xxx wrappers for htable routines
   which already existed.
2. Sometimes destructors really are used for side-effects (eg. to simply
   mark that something was freed): these are clearer with boutique names.
3. Generally destructors are static, but they don't need to be: in some
   cases we attach a destructor then remove it later, or only attach
   to *some* cases.  These are best with qualifiers in the destroy_<type>
   name.

This provides a sanity check that we are in sync, and also keeps the

Since the destructor now doesn't clean up the peer, there are some
wider changes to be made when cleaning up.  Most notably we create
lots of channels in run-wallet.c and they previously freed the peer:
now we need free the peer explicitly, so we need to free them first.

For performance, we delay entering the 'wallet_payment' into the db
until we actually commit to the HTLC (when we have to touch the DB

This opens a race where we can try to pay twice, and since it's not in

So remove the temporary payment field from htlc_out, which was always
an uncomfortable hack, and make the wallet code abstract over the
deferred entry a little by maintaining a 'unstored_payments' list

Rusty Russell 0237e0b28c bitcoin: create new wrapper type bitcoin_txid, log backward endianness.
It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_txid_to_hex() so it's reversed as people expect.

William Casarin d89eb32c85 wallet: insert address into peers table
It looks like we were missing the address on insert into the peers table. This
will insert the address formatted by fmt_wireaddr. This happens to include the
ip and port.

This is fine, since parse_wireaddr has been updated to parse ports in ip address
strings.

Rusty Russell 3543530172 build_utxos: fix weight calculation, and make more accurate.
Accuracy improvements:

1. We assumed the output was a p2wpkh, but it can be user-supplied now.
2. We assumed we always had change; remove this for wallet_select_all.

Calculation out-by-one fixes:

1. We need to add 1 byte (4 sipa) for the input count.
2. We need to add 1 byte (4 sipa) for the output count.
3. We need to add 1 byte (4 sipa) for the output script length for each output.
4. We need to add 1 byte (4 sipa) for the input script length for each input.
5. We need to add 1 byte (4 sipa) for the PUSH optcode for each P2SH input.

The results are now a slight overestimate (due to guessing 73 bytes
for signature, whereas they're 71 or 72 in practice).

Fixes: #458

Christian Decker 6beb4eb171 wallet: Fix a column mismatch and use absolute column indices
We weren't incrementing the `col` for the `local_shutdown_idx` field,
which meant that all following fields were incorrect. I removed the
`col` computation and opted for absolute indices instead, since they
are way less brittle. Just remember to add new fields to the query at
the end so we don't have to shift too often :-)
