Since we are planning to release a bug fix release, and the plugin
subsystem is not yet complete, it is better to make plugin support
opt-in while we continue testing.

git is needed to generate version information
Add a sanity check so that the build don't continue with an empty VERSION. This
is useful for sandboxed build where we might have forgot to include git.

Fortunately, we can calculate the sha256 ourselves, so the
outgoing channeld doesn't need to tell us.

The node which sent the error is doing so because the following
one sent WIRE_UPDATE_FAIL_MALFORMED_HTLC.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
When the next node tells us the onion is malformed, we now actually
report the failcode to lightningd (rather than generating an invalid
error as we do now).
We could generate the onion at this point, but except we don't know
the shared secret; we'd have to plumb that through from the incoming
channeld's HTLC.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This covers all the cases where an onion can be malformed; this means
we know in advance that it's bad. That allows us to distinguish two
cases: where lightningd rejects the onion as bad, and where the next
peer rejects the next onion as bad. Both of those (will) set failcode
to one of the BADONION values.

It's more natural than using a zero-secret when something goes wrong.
Also note that the HSM will actually kill the connection if the ECDH
fails, which is fortunately statistically unlikely.

We currently use 'all-zeroes' as 'unknown', but NULL is more natural
even if we have to send it as all-zeroes over the wire due to
expressiveness limitations in our generation code.

If the `request` or `plugin` parameter that are injected by the
framework where before or inbetween positional arguments we'd be
injecting them incorrectly, i.e., we'd be providing them both as
`args` (and mismapping another argument) as well as `kwargs`.
This is a better way to map arguments, which takes advantage of the
fact that JSON-RPC calls are either all positional or named arguments.
I also included a test for various scenarios, that hopefull cover the
most common cases.

The processes that were used to test the subdaemon versions were not
reaped correctly keeping some resources bound.

The example code had the `plugin` argument as the last argument. this disallows arguments that have a standard value. As far as I understand the dispatching code the order of arguments does not matter since it is the name `plugin` that is relevant. Therefor I changed the order so that newbe's don't have to read the entire code and can easily add optional arguments

Just like we added the RPC methods, the notification handlers can also
be registered using a function decorator, and we auto-subscribe when
asked for a manifest.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
This used to be request-specific, but we now want to send
notifications and requests. As a drive-by we also clarify the
ownership of the json_stream instance that is being sent.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
Will be used in the next commit to fan out notifications to multiple
subscribing plugins. We can't just use `tal_dup` from outside since
the definition is hidden outside the compilation unit.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
Otherwise recent additional checks in tal() complain that we're freeing a
take() pointer. In this case, we're exiting so it's harmless, but it's
still a latent bug.

This was causing `listchannels` to be incredibly slow. The response is
several megabyte in size, and we were only buffering 1Kb on each
iteration.

memdump iterates through the various daemons asking them to check for
leaks.
We currently call openingds (there might be none), channelds (there
might be none), then hsmd synchronously (the other daemons). If hsmd
reports a leak, we'll fail the dev-memleak command immediately.
Change the order to call connectd first; that's always async, so we
can happily mark the command still pending.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This causes a compiler warning if we don't do something with the
result (hopefully return immediately!).
We use was_pending() to ignore the result in the case where we
complete a command in a callback (thus really do want to ignore
the result).
This actually fixes one bug: we didn't return after command_fail
in json_getroute with a bad seed value.
