Should actually be BTC (or satoshis?) per byte, since we no longer do it per kB...

sipa · 2016-06-06T18:18:39Z

All RPC arguments use BTC/kByte, no?

jonasschnelli · 2016-06-06T18:19:36Z

It should be the same format than bitcoind spit out when one calls estimatefee.

maflcko · 2016-06-06T19:51:20Z

@jonasschnelli et al: Added a commit so I don't have to modify the univalue subtree. (Added a UniValueType wrapper instead)

fanquake · 2016-06-07T02:27:05Z

nit s/sat/set

it is probably satoshis. But not very clear, yes.

Thanks, will fix the comment.

laanwj · 2016-06-07T06:46:53Z

BTC/kB is fine, we use that for fee rates on the interface everywhere. The point of this change is to reduce the variety of different ways in which the same is expressed on the interface, not come up with something new.

utACK faf82e8

I think @luke-jr was referring to kB no longer being the smallest unit. Currently we use Byte to be the smallest unit.

(Force pushed after fixing comment-nit)

jonasschnelli · 2016-06-07T09:11:23Z

Not sure if I got this right, but why not just removing the "feeRate" from the RPCTypeCheckObj check (it's optional anyways)? I don't see the reason for the new UniValueType type.

maflcko · 2016-06-07T09:27:45Z

We also want to suppress passing in unrecognized parameters. (Try removing it and see where the rpc tests fail. Hint: fStrict is set to true)

jonasschnelli · 2016-06-07T09:32:32Z

Ah. Right. Makes sense.
Is there no way to avoid the UniValueType wrapper? Using UniValue::VNULL for a type-independent check? Or would a C++11 union be simpler?

sipa · 2016-06-07T09:38:40Z

typedef is not needed for structs and classes in C++.

Fixed.

Also changed to union as suggested by @jonasschnelli

jonasschnelli · 2016-06-07T10:55:14Z

Nice!

This is not valid. You can only access fields of a union that you know was the last one assigned to. Testing both typeAny and type certains violates that property at least once.

Right, I should probably just do s/union/struct/ to revert to struct.

I agree. It's very easy to violate the requirements of using an union accidentally, resulting in horrible hard to debug issues, I'd prefer not using them unless it's a place where the additional memory usage is critical. I don't think that's the case here.

done. Hope I got it right this time. 👍

Also introduce UniValueType UniValueType is a wrapper for UniValue::VType which allows setting a typeAny flag. This flag indicates the type does not matter. (Used by RPCTypeCheckObj)

laanwj · 2016-06-07T12:22:05Z


        if (options.exists("feeRate"))
        {
-            feeRate = CFeeRate(options["feeRate"].get_real());


We slipped up with the review for #7967, shouldn't have allowed using get_real here. Good that this is being replaced.

On the other hand, imagine if someone noticed it while reviewing #7967: The pull probably would have never made it into 0.13 before feature freeze, because adding the anytype is a non-trivial refactor and review is hard to do when there is substantial refactoring going on while adding new features.

Looking at it from this perspective, it makes sense to have two pulls to aid review.
