      Deprecate `RewardDestination::Controller` (#2380) · 7a32f4be
      Ross Bulat authored 
      

Deprecates `RewardDestination::Controller` variant.

- [x] `RewardDestination::Controller` annotated with `#[deprecated]`.
- [x] `Controller` variant is now handled the same way as `Stash` in
`payout_stakers`.
- [x] `set_payee` errors if `RewardDestination::Controller` is provided.
- [x] Added `update_payee` call to lazily migrate
`RewardDestination::Controller` `Payee` storage entries to
`RewardDestination::Account(controller)` .
- [x] `payout_stakers_dead_controller` has been removed from benches &
weights - was not used.
- [x] Tests no longer use `RewardDestination::Controller`.

      [NPoS] Paging reward payouts in order to scale rewardable nominators (#1189) · 00b85c51
      Ankan authored 
      helps https://github.com/paritytech/polkadot-sdk/issues/439.
closes https://github.com/paritytech/polkadot-sdk/issues/473.

PR link in the older substrate repository:
https://github.com/paritytech/substrate/pull/13498.

# Context
Rewards payout is processed today in a single block and limited to
`MaxNominatorRewardedPerValidator`. This number is currently 512 on both
Kusama and Polkadot.

This PR tries to scale the nominators payout to an unlimited count in a
multi-block fashion. Exposures are stored in pages, with each page
capped to a certain number (`MaxExposurePageSize`). Starting out, this
number would be the same as `MaxNominatorRewardedPerValidator`, but
eventually, this number can be lowered through new runtime upgrades to
limit the rewardeable nominators per dispatched call instruction.

The changes in the PR are backward compatible.

## How payouts would work like after this change
Staking exposes two calls, 1) the existing `payout_stakers` and 2)
`payout_stakers_by_page`.

### payout_stakers
This remains backward compatible with no signature change. If for a
given era a validator has multiple pages, they can call `payout_stakers`
multiple times. The pages are executed in an ascending sequence and the
runtime takes care of preventing double claims.

### payout_stakers_by_page
Very similar to `payout_stakers` but also accepts an extra param
`page_index`. An account can choose to payout rewards only for an
explicitly passed `page_index`.

**Lets look at an example scenario**
Given an active validator on Kusama had 1100 nominators,
`MaxExposurePageSize` set to 512 for Era e. In order to pay out rewards
to all nominators, the caller would need to call `payout_stakers` 3
times.

- `payout_stakers(origin, stash, e)` => will pay the first 512
nominators.
- `payout_stakers(origin, stash, e)` => will pay the second set of 512
nominators.
- `payout_stakers(origin, stash, e)` => will pay the last set of 76
nominators.
...
- `payout_stakers(origin, stash, e)` => calling it the 4th time would
return an error `InvalidPage`.

The above calls can also be replaced by `payout_stakers_by_page` and
passing a `page_index` explicitly.

## Commission note
Validator commission is paid out in chunks across all the pages where
each commission chunk is proportional to the total stake of the current
page. This implies higher the total stake of a page, higher will be the
commission. If all the pages of a validator's single era are paid out,
the sum of commission paid to the validator across all pages should be
equal to what the commission would have been if we had a non-paged
exposure.

### Migration Note
Strictly speaking, we did not need to bump our storage version since
there is no migration of storage in this PR. But it is still useful to
mark a storage upgrade for the following reasons:

- New storage items are introduced in this PR while some older storage
items are deprecated.
- For the next `HistoryDepth` eras, the exposure would be incrementally
migrated to its corresponding paged storage item.
- Runtimes using staking pallet would strictly need to wait at least
`HistoryDepth` eras with current upgraded version (14) for the migration
to complete. At some era `E` such that `E >
era_at_which_V14_gets_into_effect + HistoryDepth`, we will upgrade to
version X which will remove the deprecated storage items.
In other words, it is a strict requirement that E<sub>x</sub> -
E<sub>14</sub> > `HistoryDepth`, where
E<sub>x</sub> = Era at which deprecated storages are removed from
runtime,
E<sub>14</sub> = Era at which runtime is upgraded to version 14.
- For Polkadot and Kusama, there is a [tracker
ticket](https://github.com/paritytech/polkadot-sdk/issues/433) to clean
up the deprecated storage items.

### Storage Changes

#### Added
- ErasStakersOverview
- ClaimedRewards
- ErasStakersPaged

#### Deprecated
The following can be cleaned up after 84 eras which is tracked
[here](https://github.com/paritytech/polkadot-sdk/issues/433).

- ErasStakers.
- ErasStakersClipped.
- StakingLedger.claimed_rewards, renamed to
StakingLedger.legacy_claimed_rewards.

### Config Changes
- Renamed MaxNominatorRewardedPerValidator to MaxExposurePageSize.

### TODO
- [x] Tracker ticket for cleaning up the old code after 84 eras.
- [x] Add companion.
- [x] Redo benchmarks before merge.
- [x] Add Changelog for pallet_staking.
- [x] Pallet should be configurable to enable/disable paged rewards.
- [x] Commission payouts are distributed across pages.
- [x] Review documentation thoroughly.
- [x] Rename `MaxNominatorRewardedPerValidator` ->
`MaxExposurePageSize`.
- [x] NMap for `ErasStakersPaged`.
- [x] Deprecate ErasStakers.
- [x] Integrity tests.

### Followup issues

      `xcm`: Change `TypeInfo::path` to not include `staging` (#1948) · f3bf5c1a
      Bastian Köcher authored 
      The `xcm` crate was renamed to `staging-xcm` to be able to publish it to
crates.io as someone as squatted `xcm`. The problem with this rename is
that the `TypeInfo` includes the crate name which ultimately lands in
the metadata. The metadata is consumed by downstream users like
`polkadot-js` or people building on top of `polkadot-js`. These people
are using the entire `path` to find the type in the type registry. Thus,
their code would break as the type path would now be [`staging_xcm`,
`VersionedXcm`] instead of [`xcm`, `VersionedXcm`]. This pull request
fixes this by renaming the path segment `staging_xcm` to `xcm`.

This requires: https://github.com/paritytech/scale-info/pull/197

      Refactor staking ledger (#1484) · 8ee4042c
      Gonçalo Pestana authored 
      This PR refactors the staking ledger logic to encapsulate all reads and
mutations of `Ledger`, `Bonded`, `Payee` and stake locks within the
`StakingLedger` struct implementation.

With these changes, all the reads and mutations to the `Ledger`, `Payee`
and `Bonded` storage map should be done through the methods exposed by
StakingLedger to ensure the data and lock consistency of the operations.
The new introduced methods that mutate and read Ledger are:

- `ledger.update()`: inserts/updates a staking ledger in storage;
updates staking locks accordingly (and ledger.bond(), which is synthatic
sugar for ledger.update())
- `ledger.kill()`: removes all Bonded and StakingLedger related data for
a given ledger; updates staking locks accordingly;
`StakingLedger::get(account)`: queries both the `Bonded` and `Ledger`
storages and returns a `Option<StakingLedger>`. The pallet impl exposes
fn ledger(account) as synthatic sugar for `StakingLedger::get(account)`.

Retrieving a ledger with `StakingLedger::get()` can be done by providing
either a stash or controller account. The input must be wrapped in a
`StakingAccount` variant (Stash or Controller) which is treated
accordingly. This simplifies the caller API but will eventually be
deprecated once we completely get rid of the controller account in
staking. However, this refactor will help with the work necessary when
completely removing the controller.

Other goals:

- No logical changes have been introduced in this PR;
- No breaking changes or updates in wallets required;
- No new storage items or need to perform storage migrations;
- Centralise the changes to bonds and ledger updates to simplify the
OnStakingUpdate updates to the target list (related to
https://github.com/paritytech/polkadot-sdk/issues/443)

Note: it would be great to prevent or at least raise a warning if
`Ledger<T>`, `Payee<T>` and `Bonded<T>` storage types are accessed
outside the `StakingLedger` implementation. This PR should not get
blocked by that feature, but there's a tracking issue here
https://github.com/paritytech/polkadot-sdk/issues/149
