STF Vectors

GP Version 0.6.4

Keeping up to date all the PRs has become overwhelming.

This PR superseeds the previous STF vectors PRs.

In the future, the other PRs may be reopened to merge individual subsystems' STFs separately. For now, I prefer to consolidate everything into a single PR.

I think there are some issue on WorkResult binary encoding. work_result_0.bin contains the following:

04 03 02 01 70 A5 08 29 85 1E 8F 6A 8C 80 F9 28 06 AE 0E 95 EB 7C 06 AD 06 4E 31 1C C3 91 07 B3 21 9E 53 2E FA 99 B9 7E 72 FC FA EF 61 61 08 DE 98 1A 59 DC 33 10 E2 A9 F5 E7 3C D4 4D 70 2E CA AC CD 86 96 2A 00 00 00 00 00 00 00 00 03 AA BB CC 00 00 00 00 00

Inspecting the final part:

• 00 03 AA BB CC - is the result status (0 - OK) + size of payload (3) + the payload
• then we should have 8 + 2 + 2 + 4 + 2 = 18 bytes (for gas_used + RefineLoad), while we have 5 bytes only

Inspecting the final part:

* 00 03 AA BB CC - is the result status (0 - OK) + size of payload (3) + the payload

* then we should have 8 + 2 + 2 + 4 + 2 = 18 bytes (for gas_used + RefineLoad), while we have 5 bytes only

Before I dig in, these fields are using compact encoding. Have you checked that?

My fault; I was using the size version of integer encoding.

Hey davxy in the test stats_with_epoch_change-1 under statistics i have a newly created service statistic with ServiceIndex=0 with the following data:

{
    imports: 0,
    exports: 0,
    extrinsicSize: 0,
    extrinsicCount: 0,
    refinement: { count: 2, usedGas: 0n },
    provided: { count: 3, size: 51 },
    accumulate: { count: 0, usedGas: 0n },
    transfers: { count: 0, usedGas: 0n }
  }

it seems correct on my end as this service appears in both Ep and r

note:

• i am currently feeding in the transfer & accumulate statistics with empty data as they're not provided as input
• for coreStatistics i am feeding in rho dagger

I think there is an issue with the new codec for ServiceActivityRecord.

Some of the attributes are not in the correct order (due to typo in GP)

So instead of

...
imports 
extrinsic-count
extrinsic-size
exports
...

it should be

...
imports 
exports
extrinsic-size
extrinsic-count
...

Exports moves up, and the two extrinsic ones need to be swapped.

Please see gavofyork/graypaper#315

@davxy I think accumulate tests are not valid for 0.6.4, since the test service is compiled using jam-types==0.1.12, were the AccumulateItem is missing exports_root and authorizer_hash introduced with 0.6.4: https://docs.rs/jam-types/0.1.12/jam_types/struct.AccumulateItem.html
