This triple join should be efficient to read, and to process. We have a
one-to-many (tx-to-annotations), followed by a
one-to-one (annotation-to-channel) join, so we are limited to annotations x
transactions results.
This avoids having to correlate with listpeers for the most pertinent
information.
This API predates plugins, otherwise we'd have listutxos and listpeers
and this would simply combine them appropriately. Still, it exists so
there's little reason not to make it more friendly.

Allow a user to select the utxo set that will be added to a
transaction, via the `utxos` parameter. Optional.
Format for utxos should be of the form ["txid:vout","..."]
The withdraw_tx function shouldn't use it, but GCC is right it's uninitialized:
wallet/walletrpc.c: In function ‘json_prepare_tx’:
wallet/walletrpc.c:202:15: error: ‘changekey’ may be used uninitialized in this function [-Werror=maybe-uninitialized]

The way we build transactions, serialize them, and compute fees depends on the
chain we are working on, so let's add some context to the transactions.

Due to API instability we are disabling the RPC method for this release, but

We're going to need this for P2WSH scripts. pull it out into
a common file plus adopt the sanity checks so that it will allow for
either P2WSH or P2WPKH (previously only encoded P2WPKH scripts)
"result" should always be an object (so that we can add new fields),
so make that implicit in json_stream_success.
This makes our primitives well-formed: we previously used NULL as our
fieldname when calling the first json_object_start, which is a hack
since we're actually in an object and the fieldname is 'result' (which
was already written by json_object_start).
There were only two cases which didn't do this:
1. dev-memdump returned an array. No API guarantees on this.
2. shutdown returned a string.
I temporarily made shutdown return an empty object, which shouldn't
break anything, but I want to fix that later anyway.

This allows you to prepare a tx, then release or discard it later.
Shares almost all the code with json_withdraw (which is now technically
superfluous).

We currently allocate utxos off cmd, but the next commit will persist a
wtx beyond the command which created it, breaking that assumption.
In general, a struct member should be owned by the struct itself, and
a tal context should be an explicit arg, not implicit.

We generally want to do as much validation as possible inside
parameter parsing, as that means the 'check' command detects more
erroneous uses. In this case, we can try to interpret the destination
address as soon as we encounter it.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
As a side-effect, we now only add txfilters for addresses we actually
expose, rather than always filtering for both p2sh and native segwit.

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.

A new string field is added to the command structure and is specified at the creation of each native command, and in the JSON created by 'json_add_help_command()'.
New fields don't have to be spelled out twice.
The raw version are called _only, so we don't miss a call
accidentally. We can rename them when we finally deprecated old
fields.

The chainparams are needed to know the prefixes, so instead of passing down
the testnet, we pass the entire params struct.

I tried to just do gossipd, but it was uncontainable, so this ended up being
a complete sweep.
We didn't get much space saving in gossipd, even though we should save
24 bytes per node.

In particular this matches the case of `their_unilateral/to_us` outputs, which
were missing their addresses so far.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
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`.

This allows us to specify that an output must have been confirmed before the
given maximum height. This allows us to specify a minimum number of
confirmations for an output to be selected.

As a side-effect of using amount_msat in gossipd/routing.c, we explicitly
handle overflows and don't need to pre-prune ridiculous-fee channels.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Using param_tok is generally deprecated, as it doesn't give any sanity checking
for the JSON 'check' command. So make param_wtx usable directly, and
also make it have a struct amount_sat.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We store it in a strmap. This means we call the jsonrpc handler earlier,
so all callers need to call param() before they do anything else; only
json_listaddrs and json_help needed fixing.
Plugins still use '[usage]' for now.

Add the change output to owned_txfilter so its entry in db will
get a confirmation_height when detected in a block by filter_block_txs
before this commit, after a 'withdraw' command, 'listfunds' would
not show our change outputs as confirmed
Modified the log message in wallet_extract_owned_outputs to
append 'CONFIRMED' when it is called with a blockheight arg.
To make distinction between (1st call) when adding owned output to the
db and (2th call) when confirmed in block.
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.

Usually, this means they return 'command_param_failed()' if param()
fails, and changing 'command_success(); return;' to 'return
command_success()'.
Occasionally, it's more complex: there's a command_its_complicated()
for the case where we can't exactly determine what the status is,
but it should be considered a last resort.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Handers of a specific form are both designed to be used as callbacks
for param(), and also dispose of the command if something goes wrong.
Make them return the 'struct command_result *' from command_failed(),
or NULL.
Renaming them just makes sense: json_tok_XXX is used for non-command-freeing
parsers too.

json_escaped.[ch], param.[ch] and jsonrpc_errors.h move from lightningd/
to common/. Tests moved too.
We add a new 'common/json_tok.[ch]' for the common parameter parsing
routines which a plugin might want, taking them out of
lightningd/json.c (which now only contains the lightningd-specific
ones).
The rest is mainly fixing up includes.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This (will) avoid the plugin having to walk back from the params object
as it currently does.
No code changes; I removed UNUSED and UNNEEDED labels from the other
parameters though (as *every* json_rpc callback needs to call param()
these days, they're *always* used).
