Add best block indicator to informant message + print parent block on import message (#4021)
Sometimes you need to debug some issues just by the logs and reconstruct what happened. In these scenarios it would be nice to know if a block was imported as best block, and what it parent was. So here I propose to change the output of the informant to this: ``` 2024-04-05 20:38:22.004 INFO ⋮substrate: [Parachain]✨ Imported #18 (0xe7b3…4555 -> 0xbd6f…ced7) 2024-04-05 20:38:24.005 INFO ⋮substrate: [Parachain]✨ Imported #19 (0xbd6f…ced7 -> 0x4dd0…d81f) 2024-04-05 20:38:24.011 INFO ⋮substrate: [jobless-children-5352]🌟 Imported #42 (0xed2e…27fc -> 0x718f…f30e) 2024-04-05 20:38:26.005 INFO ⋮substrate: [Parachain]✨ Imported #20 (0x4dd0…d81f -> 0x6e85…e2b8) 2024-04-05 20:38:28.004 INFO ⋮substrate: [Parachain]🌟 Imported #21 (0x6e85…e2b8 -> 0xad53…2a97) 2024-04-05 20:38:30.004 INFO ⋮substrate: [Parachain]🌟 Imported #22 (0xad53…2a97 -> 0xa874…890f) ``` --------- Co-authored-by:Bastian Köcher <[email protected]>
