User @rainbow-promise, please sign the CLA here. |

Need to take a closer look at the extrinsic executions, even with the revisions it Is not quit there yet. |
|
looks fine now. need proper weights |
|
I am guessing the weight signature below the pallet index will have some form of condition as well? |
|
use the worst case (i.e. main + fallback). extra weight will be refunded as the actual weight is returned in the call |
this also applies to dispatch class? |
I would say dispatch class is the lowest class of the 2. if both are operational then it is operational. if one is normal then it is normal. etc. |

The err branch should be slightly more costly, but difference should be negligible so it is ok.

Ok.
Thanks for the review

You can use a root call, it will be failing, like set_heap_page.
This would benchmark for the failing case, which is more costly

@gui1117 the event passes for cargo test -p pallet-utility --features runtime-benchmarks
but fails when generating weights for runtimes

@shawntabrizi A referendum for a medium (80 DOT) tip was successfully submitted for @rainbow-promise (1HbdqutFR8M535LpbLFT41w3j7v9ptEYGEJKmc6PKpqthZ8 on polkadot). Referendum number: 1327. |

The referendum has appeared on Polkassembly. |
Utility Call Fallback
This introduces a new extrinsic:
if_elseWhich first attempts to dispatch the
maincall(s). If themaincall(s) fail, thefallbackcall(s) is dispatched instead. Both calls are executed with the same origin.In the event of a fallback failure the whole call fails with the weights returned.
Use Case
Some use cases might involve submitting a
batchtype call in either main, fallback or both.Resolves #6000
