typo 86 != 98

maybe it should be u64::max_value() instead of 0 until we release?

Makes sense to enable this when other metropolis changes are ready.

one more :)

ugh, I'm going to replace it with Schedule::from_params for DRY after #4757 is merged. https://github.com/ethcore/parity/pull/4757/files#diff-ef2687136b4e032043a492e9e53dcb7cR177

what's the rationale behind EnvInfo -> BlockNumber change?

arkpar · 2017-03-31T13:25:39Z

There's a number of places now where Schedule is created from the block number. Creating a fake EnvInfo struct seems wasteful.

arkpar · 2017-03-31T14:39:13Z

Updated with recent EIP changes. gasprice, noce, value are now required to be zero for unsigned transactions.

why &EnvInfo -> BlockNumber?

There's a number of places where Schedule is created from the block number number. This PR introduces quite a few more. Creating a fake EnvInfo struct seems wasteful. And furthermore since all of the data except for the block number is unreliable it may introduce subtle bugs if any future implementation will have to rely on any other field.

YP & EIP state that this should be the null sender (i.e. zero address). am i missing something?

I think the fix is wrong (and I was mistaken in a PR to YP).

The relevant EIP says the pad is 0xffff..ff. The NULL_SENDER is defined to be 0xffff..ff.

overwrite existing what?

removed that param since it is already in the schedule.

one probable correction needed and a few clarifications.
