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.

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.

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).

- mock_rpc function now returns full JSON-RPC response, is much cleaner
- Since reached_announce_depth counting is fixed when starting
channeld, we don't need the 7th block to tell depth anymore.
It would always return bech32; fix that, and don't bother printing
it if they use the (new) 'all' parameter.
This API was introduced in 3e67c09d5e,
which means it wasn't in a release so no CHANGELOG entry necessary.

Reorg changes short_channel_id after lockin of private channel, while
one node restarts.
test that:
- peer->depth_togo in billboard decrements
- reorg and scid change is detected by running node and restarting node
- both `old` and `new` scids are in rtable
Also added a comment to test_blockchaintrack to clarify.
Because the call (wallet_extract_owned outputs) that prints that line can happen
_before_ or _after_ confirmation in block, adding `CONFIRMED` in the later.
This brings up an interesting quirk though, in that we report "3
attempts", where we really should have done one.

Fixes#2518
Signed-off-by: Christian Decker <decker.christian@gmail.com>
Changelog-fixed: `minconf` no longer gets wrapped around for large values, which was causing funds with insufficient confirmations to be selected.
The user can explicitly create such things (within [] or ") as we paste
those cases literally, but not for the simple cases.
Fixes: #2550

They don't clean up after themselves, so best we do it here (by this
point we've already done the pid check to make sure we're the only
lightningd here anyway).

In particular, the assert when `--addr=/sockname` is used, and that it
doesn't clean up on restart, requiring manual deletion of the socket.

We want to disallow using unconfirmed outputs by default, so making the
default 1 confirmation seems a good idea. This also matches `bitcoind`s
minimum confirmation requirement.
Arming however breaks some of our tests, so I used `minconf=0` for the
breaking tests and added a new test specifically for the `minconf` parameter
for `fundchannel`.

We use the 'exclude' option to getroute for successive attempts. This
is more robust than having gossipd disable for some limited time.

Fortunately, we can calculate the sha256 ourselves, so the

The node which sent the error is doing so because the following
one sent WIRE_UPDATE_FAIL_MALFORMED_HTLC.

We now keep multiple commands for a json_connection, and an array of
json_streams.
When a command wants to write something, we allocate a new json_stream
at the end of the array.
We always output from the first available json_stream; once that
command has finished, we free that and move to the next. Once all are
done, we wake the reader.
This means we won't read a new command if output is still pending, but
as most commands don't start writing until they're ready to write
everything, we still get command parallelism.
In particular, you can now 'waitinvoice' and 'delinvoice' and it will
work even though the 'waitinvoice' blocks.
