Now we've updated ccan/pipecmd, we can use pipecmd_preserve to
preserve stderr for plugins so we see their error spew.

Note that this changes the order of arguments to pipecmd to match the
documentation, so we fix all the callers!
Also make configure re-run when configurator changes.

This currently just invokes GDB, but we could generalize it (though
pdb doesn't allow attaching to a running process, other python
debuggers seem to).

This tells the plugin both the `lightning-dir` as well as the
`rpc-filename` to use to talk to `lightningd`. Prior to this they'd
had to guess.

This is prep work for when we sign htlc txs with
SIGHASH_SINGLE|SIGHASH_ANYONECANPAY.
We still deal with raw signatures for the htlc txs at the moment, since
we send them like that across the wire, and changing that was simply too
painful (for the moment?).

We currently hand the feature set from lightningd, but that's confusing
if they were ever different.

The check command allows us to check the parameters of a command
without running it. Example:
lightning-cli check invoice 234 foo desc
We do this by removing the "command_to_check" parameter and then using the
remaining parameters as-is.
I chose the parameter name "command_to_check" instead of just "command" because
it must be unique to all other parameter names for all other commands. Why?
Because it may be ambiguous in the case of a json object, where the parameters are
not necessary ordered. We don't know which one is the command to check and
which one is a parameter.

We can now set a flag to have param() ignore unexpected parameters.
Normally unexpected parameters are considered errors.
Needed by the check command.

This used to be a use-after-free bug in which we'd free the plugin and
then still have two connections that expect to be able to operate on
the plugin. This now signals the connections to exit and cleans up
once they do.

We can use the internal buffering of the json_stream instead of
manually building JSON-RPC calls. This makes it a lot easier to handle
these requests.
Notice that we do not flush concurrently and still buffer all the
things, but it avoids double-buffering things.

If the plugin fails to respond to we may end up hanging indefinitely,
so we limit the time we're willing to wait to 10 seconds.

I had this really contorted way of iterating over options that could
cause valgrind to choke. This is the much more intuitive way to
iterate.

The final step in the JSON-RPC passthrough: map the result we got from
the plugin back to the original request we got from the client.

This is needed in order to be able to add methods while initializing
the plugins, but before actually moving to the config dir and starting
to listen.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
Unlike other daemons, closingd doesn't listen to the master, but runs
simply to its own beat. So instead of responding to the JSON dev_memleak
command, we always check for memory leaks, and make sure that the
python tests fail if they see MEMLEAK in the logs.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
For onchaind we need to remove globals from memleak consideration;
we also change the htlc pointer to an htlc copy, which simplifies
things as well.

This is a bit different from the other cases: we need to iterate through
the peers and ask all the ones in openingd.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We need several notleak() annotations here:
1. The temporary structure which is handed to retry_peer_connected().
It's waiting for the master to respond to our connect_reconnected
message.
2. We don't keep a pointer to the io_conn for a peer, so we need to
mark those as not being a leak.
