The `json_tok_X` functions now consistently check the success case first and call `command_fail` at the end. Signed-off-by: Mark Beckwith <wythe@intrig.com>
We were returning a pointer but expecting a bool. Signed-off-by: Mark Beckwith <wythe@intrig.com>
Note: Unlike before, this will now accept positional parameters. Note: In case of error we no longer report the hop number. Is this acceptable? We still report the name of the bad param and its value. One option is to log the hop number if param() returns false. This would require a change to command_fail so it doesn't delete the cmd, so we can still access cmd->ld->log. Signed-off-by: Mark Beckwith <wythe@intrig.com>
Added utility function json_tok_is_num so I would avoid using goto. Signed-off-by: Mark Beckwith <wythe@intrig.com>

This could have been a local static but its used by the run-param test, so putting it in json.c made things easier. Signed-off-by: Mark Beckwith <wythe@intrig.com>

@renepickhardt: why is it actually lightningd.c with a d but hsm.c without d ? And delete unused gossipd/gossip.h. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Code changes: 1. Expose daemon_poll() so lightningd can call it directly, which avoids us having store a global and document it. 2. Remove the (undocumented, unused, forgotten) --rpc-file="" option to disable JSON RPC. 3. Move the ickiness of finding the executable path into subd.c, so it doesn't distract from lightningd.c overview. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Documentation changes: 1. Lots of extra detail suggested by @renepickhardt. 2. typo fixes from @practicalswift. 3. A section on 'const' usage. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

It's an array: we were only saving the single element; if there was more than one changed HTLC we'd get a bad signature! The report in #1907 is probably caused by the other side re-requesting something we considered already finalized; to avoid this particular error, we should set the field to NULL if there's no last_sent_commit. I'm increasingly of the opinion we want to just save all the update packets to the db and blast them out, instead of doing this second-guessing dance. Fixes: #1907 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Installing pytest through pip3 (at least sometimes) doesn't create a script. This means calling `which` won't work. Changed configure so that it can also test if the module is present by calling python/python3. Change the error message for when pytest can't be found, so that it's clear to the user `configure` must be ran again after installing pytest.

converting a block number to an scid truncates it at 24 bits. When we look through the index from (truncated number) to (real end number) we get every channel, which is too large to encode, so we iterate again. This fixes both that problem, and also the issue that we'd end up dividing into many empty sections until we get to the highest block number. Instead, we just tack the empty blocks on to then end of the final query. (My initial version requested 0xFFFFFFFE blocks, but the dev code which records what blocks were returned can't make a bitmap that big on 32 bit).

To fix this, we actually make 'ld->timers' a pointer, so we can clean
it up last of all. We can't free it before ld, because that causes
timers to be destroyed.

The variable `block` (instace of `struct block`) is
allocated on the stack without being initialized, i.e. its
member `prev` points to nowhere. This causes a segmentation
fault on my machine on the binding of "prev_hash" on running
`wallet_block_add`, as the following core-dump analysis
shows:
$ egdb ./wallet/test/run-wallet ./run-wallet.core
[...]
Core was generated by `run-wallet'.
Program terminated with signal SIGSEGV, Segmentation fault.

Adding an index means: 1. Add the new subsystem, and new updated_index field to the db, and create xxx_index_deleted/created/updated APIs. 2. Hook up these functions to the points they need to be called. 3. Add index, start and limit fields to the list command. 4. Add created_index and updated_index into the list command. This does #1.
