TLDR: Thanks to a number of reports from Kusama validator, we have been investigating an issue where the self stake of some validators is not present in `ErasStakersPaged` and `ErasStakersOverview`, and consequently not earning staking rewards. After investigation, it was clear that the `polkadot-staking-miner` is doing the right thing, and the self-stake is indeed submitted to the chain as a part of the staking election result. The root cause in how `pallet-staking-async` ingests the staking election result. This code **made a (wrong) assumption that self-stake is only present in the first page of a multi-page election. This PR fixes this issue.** --- - [x] (nice to have) revisit try-state checks of the pallet, `ErasStakersPaged`, `ErasStakersOverview` and `ErasTotalStake` are triple checked for correctness - [ ] (nice to have) fix related displays in PJS: polkadot-js/apps#11930 - [ ] backport to 2507 and 2509 - Westend - [ ] Find a similar issue in westend for monitoring (paritytech/devops#4402) - [ ] Upgrade westend to a branch/release containing this fix - [ ] Upgrade westend with this fix, observe test examples are resolved - [ ] Bump backported version in `fellowship/runtimes` - [ ] Release 1.9.3 for Kusama with this fix - [ ] Ensure known test cases are fixed - One example: `F2WyUUFXLYnBg6acv7t2KFzH6D7CyNcvC4mRCwUdsHTUB4t` (in election round 46, likely repeating in subsequent ones too) - This PR will be part of Polkadot release 2.0.0, the Polkadot AHM. - [ ] Forum post with further explanation once PR is merged. --------- Co-authored-by: cmd[bot] <41898282+github-actions[bot]@users.noreply.github.com> (cherry picked from commit 56e4b10)
