Rusty Russell	819078fe18	param: make command_fail/command_success WARN_UNUSED_RESULT. 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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	6 years ago
Rusty Russell	93bf7c4839	param: make command sinks (fail/success) return a special type. These routines free the 'struct command': a common coding error is not to return immediately. To catch this, we make them return a non-NULL 'struct command_result *', and we're going to make the command handlers return the same (to encourage 'return command_fail(...)'-style usage). We also provide two sources for external use: 1. command_param_failed() when param() fails. 2. command_its_complicated() for some complex cases.

Rusty Russell	3f16c9a665	param: abstract 'struct command' so param doesn't need to access it. I want to use param functions in plugins, and they don't have struct command. I had to use a special arg to param() for check to flag it as allowing extra parameters, rather than adding a one-use accessor. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	6 years ago

param: make command_fail/command_success WARN_UNUSED_RESULT.

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.

param: make command sinks (fail/success) return a special type.

These routines free the 'struct command': a common coding error is not
to return immediately.

To catch this, we make them return a non-NULL 'struct command_result
*', and we're going to make the command handlers return the same (to
encourage 'return command_fail(...)'-style usage).

We also provide two sources for external use:
1. command_param_failed() when param() fails.
2. command_its_complicated() for some complex cases.

param: abstract 'struct command' so param doesn't need to access it.

I want to use param functions in plugins, and they don't have struct
command.

I had to use a special arg to param() for check to flag it as allowing
extra parameters, rather than adding a one-use accessor.
