      Revert "FRAME: Create `TransactionExtension` as a replacement for `SignedExtension` (#2280)" (#3665)
      
      This PR reverts #2280 which introduced `TransactionExtension` to replace
      `SignedExtension`.
      
      As a result of the discussion
      [here](https://github.com/paritytech/polkadot-sdk/pull/3623#issuecomment-1986789700),
      the changes will be reverted for now with plans to reintroduce the
      concept in the future.

      FRAME: Create `TransactionExtension` as a replacement for `SignedExtension` (#2280) · fd5f9292
      Gavin Wood authored
      
      
      Closes #2160
      
      First part of [Extrinsic
      Horizon](https://github.com/paritytech/polkadot-sdk/issues/2415)
      
      Introduces a new trait `TransactionExtension` to replace
      `SignedExtension`. Introduce the idea of transactions which obey the
      runtime's extensions and have according Extension data (né Extra data)
      yet do not have hard-coded signatures.
      
      Deprecate the terminology of "Unsigned" when used for
      transactions/extrinsics owing to there now being "proper" unsigned
      transactions which obey the extension framework and "old-style" unsigned
      which do not. Instead we have __*General*__ for the former and
      __*Bare*__ for the latter. (Ultimately, the latter will be phased out as
      a type of transaction, and Bare will only be used for Inherents.)
      
      Types of extrinsic are now therefore:
      - Bare (no hardcoded signature, no Extra data; used to be known as
      "Unsigned")
      - Bare transactions (deprecated): Gossiped, validated with
      `ValidateUnsigned` (deprecated) and the `_bare_compat` bits of
      `TransactionExtension` (deprecated).
        - Inherents: Not gossiped, validated with `ProvideInherent`.
      - Extended (Extra data): Gossiped, validated via `TransactionExtension`.
        - Signed transactions (with a hardcoded signature).
        - General transactions (without a hardcoded signature).
      
      `TransactionExtension` differs from `SignedExtension` because:
      - A signature on the underlying transaction may validly not be present.
      - It may alter the origin during validation.
      - `pre_dispatch` is renamed to `prepare` and need not contain the checks
      present in `validate`.
      - `validate` and `prepare` is passed an `Origin` rather than a
      `AccountId`.
      - `validate` may pass arbitrary information into `prepare` via a new
      user-specifiable type `Val`.
      - `AdditionalSigned`/`additional_signed` is renamed to
      `Implicit`/`implicit`. It is encoded *for the entire transaction* and
      passed in to each extension as a new argument to `validate`. This
      facilitates the ability of extensions to acts as underlying crypto.
      
      There is a new `DispatchTransaction` trait which contains only default
      function impls and is impl'ed for any `TransactionExtension` impler. It
      provides several utility functions which reduce some of the tedium from
      using `TransactionExtension` (indeed, none of its regular functions
      should now need to be called directly).
      
      Three transaction version discriminator ("versions") are now
      permissible:
      - 0b000000100: Bare (used to be called "Unsigned"): contains Signature
      or Extra (extension data). After bare transactions are no longer
      supported, this will strictly identify an Inherents only.
      - 0b100000100: Old-school "Signed" Transaction: contains Signature and
      Extra (extension data).
      - 0b010000100: New-school "General" Transaction: contains Extra
      (extension data), but no Signature.
      
      For the New-school General Transaction, it becomes trivial for authors
      to publish extensions to the mechanism for authorizing an Origin, e.g.
      through new kinds of key-signing schemes, ZK proofs, pallet state,
      mutations over pre-authenticated origins or any combination of the
      above.
      
      ## Code Migration
      
      ### NOW: Getting it to build
      
      Wrap your `SignedExtension`s in `AsTransactionExtension`. This should be
      accompanied by renaming your aggregate type in line with the new
      terminology. E.g. Before:
      
      ```rust
      /// The SignedExtension to the basic transaction logic.
      pub type SignedExtra = (
      	/* snip */
      	MySpecialSignedExtension,
      );
      /// Unchecked extrinsic type as expected by this runtime.
      pub type UncheckedExtrinsic =
      	generic::UncheckedExtrinsic<Address, RuntimeCall, Signature, SignedExtra>;
      ```
      
      After:
      
      ```rust
      /// The extension to the basic transaction logic.
      pub type TxExtension = (
      	/* snip */
      	AsTransactionExtension<MySpecialSignedExtension>,
      );
      /// Unchecked extrinsic type as expected by this runtime.
      pub type UncheckedExtrinsic =
      	generic::UncheckedExtrinsic<Address, RuntimeCall, Signature, TxExtension>;
      ```
      
      You'll also need to alter any transaction building logic to add a
      `.into()` to make the conversion happen. E.g. Before:
      
      ```rust
      fn construct_extrinsic(
      		/* snip */
      ) -> UncheckedExtrinsic {
      	let extra: SignedExtra = (
      		/* snip */
      		MySpecialSignedExtension::new(/* snip */),
      	);
      	let payload = SignedPayload::new(call.clone(), extra.clone()).unwrap();
      	let signature = payload.using_encoded(|e| sender.sign(e));
      	UncheckedExtrinsic::new_signed(
      		/* snip */
      		Signature::Sr25519(signature),
      		extra,
      	)
      }
      ```
      
      After:
      
      ```rust
      fn construct_extrinsic(
      		/* snip */
      ) -> UncheckedExtrinsic {
      	let tx_ext: TxExtension = (
      		/* snip */
      		MySpecialSignedExtension::new(/* snip */).into(),
      	);
      	let payload = SignedPayload::new(call.clone(), tx_ext.clone()).unwrap();
      	let signature = payload.using_encoded(|e| sender.sign(e));
      	UncheckedExtrinsic::new_signed(
      		/* snip */
      		Signature::Sr25519(signature),
      		tx_ext,
      	)
      }
      ```
      
      ### SOON: Migrating to `TransactionExtension`
      
      Most `SignedExtension`s can be trivially converted to become a
      `TransactionExtension`. There are a few things to know.
      
      - Instead of a single trait like `SignedExtension`, you should now
      implement two traits individually: `TransactionExtensionBase` and
      `TransactionExtension`.
      - Weights are now a thing and must be provided via the new function `fn
      weight`.
      
      #### `TransactionExtensionBase`
      
      This trait takes care of anything which is not dependent on types
      specific to your runtime, most notably `Call`.
      
      - `AdditionalSigned`/`additional_signed` is renamed to
      `Implicit`/`implicit`.
      - Weight must be returned by implementing the `weight` function. If your
      extension is associated with a pallet, you'll probably want to do this
      via the pallet's existing benchmarking infrastructure.
      
      #### `TransactionExtension`
      
      Generally:
      - `pre_dispatch` is now `prepare` and you *should not reexecute the
      `validate` functionality in there*!
      - You don't get an account ID any more; you get an origin instead. If
      you need to presume an account ID, then you can use the trait function
      `AsSystemOriginSigner::as_system_origin_signer`.
      - You get an additional ticket, similar to `Pre`, called `Val`. This
      defines data which is passed from `validate` into `prepare`. This is
      important since you should not be duplicating logic from `validate` to
      `prepare`, you need a way of passing your working from the former into
      the latter. This is it.
      - This trait takes two type parameters: `Call` and `Context`. `Call` is
      the runtime call type which used to be an associated type; you can just
      move it to become a type parameter for your trait impl. `Context` is not
      currently used and you can safely implement over it as an unbounded
      type.
      - There's no `AccountId` associated type any more. Just remove it.
      
      Regarding `validate`:
      - You get three new parameters in `validate`; all can be ignored when
      migrating from `SignedExtension`.
      - `validate` returns a tuple on success; the second item in the tuple is
      the new ticket type `Self::Val` which gets passed in to `prepare`. If
      you use any information extracted during `validate` (off-chain and
      on-chain, non-mutating) in `prepare` (on-chain, mutating) then you can
      pass it through with this. For the tuple's last item, just return the
      `origin` argument.
      
      Regarding `prepare`:
      - This is renamed from `pre_dispatch`, but there is one change:
      - FUNCTIONALITY TO VALIDATE THE TRANSACTION NEED NOT BE DUPLICATED FROM
      `validate`!!
      - (This is different to `SignedExtension` which was required to run the
      same checks in `pre_dispatch` as in `validate`.)
      
      Regarding `post_dispatch`:
      - Since there are no unsigned transactions handled by
      `TransactionExtension`, `Pre` is always defined, so the first parameter
      is `Self::Pre` rather than `Option<Self::Pre>`.
      
      If you make use of `SignedExtension::validate_unsigned` or
      `SignedExtension::pre_dispatch_unsigned`, then:
      - Just use the regular versions of these functions instead.
      - Have your logic execute in the case that the `origin` is `None`.
      - Ensure your transaction creation logic creates a General Transaction
      rather than a Bare Transaction; this means having to include all
      `TransactionExtension`s' data.
      - `ValidateUnsigned` can still be used (for now) if you need to be able
      to construct transactions which contain none of the extension data,
      however these will be phased out in stage 2 of the Transactions Horizon,
      so you should consider moving to an extension-centric design.
      
      ## TODO
      
      - [x] Introduce `CheckSignature` impl of `TransactionExtension` to
      ensure it's possible to have crypto be done wholly in a
      `TransactionExtension`.
      - [x] Deprecate `SignedExtension` and move all uses in codebase to
      `TransactionExtension`.
        - [x] `ChargeTransactionPayment`
        - [x] `DummyExtension`
        - [x] `ChargeAssetTxPayment` (asset-tx-payment)

        - [x] `SignedExtension` (chain-polkadot-bulletin)
        - [x] `RefundSignedExtensionAdapter`
      - [x] Implement `fn weight` across the board.
      - [ ] Go through all pre-existing extensions which assume an account
      signer and explicitly handle the possibility of another kind of origin.
      - [x] `CheckNonce` should probably succeed in the case of a non-account
      origin.
      - [x] `CheckNonZeroSender` should succeed in the case of a non-account
      origin.
      - [x] `ChargeTransactionPayment` and family should fail in the case of a
      non-account origin.
        - [ ] 
      - [x] Fix any broken tests.

      Lift dependencies to the workspace (Part 1) (#2070) · e80c2473
      Oliver Tale-Yazdi authored
      Changes (partial https://github.com/paritytech/polkadot-sdk/issues/994):
      - Set log to `0.4.20` everywhere
      - Lift `log` to the workspace
      
      Starting with a simpler one after seeing
      https://github.com/paritytech/polkadot-sdk/pull/2065 from @jsdw
      
      .
      This sets the `default-features` to `false` in the root and then
      overwrites that in each create to its original value. This is necessary
      since otherwise the `default` features are additive and its impossible
      to disable them in the crate again once they are enabled in the
      workspace.
      
      I am using a tool to do this, so its mostly a test to see that it works
      as expected.

      Fixes `TotalValueLocked` out of sync in nomination pools (#3052) · aac07af0
      Gonçalo Pestana authored
      The `TotalLockedValue` storage value in nomination pools pallet may get
      out of sync if the staking pallet does implicit withdrawal of unlocking
      chunks belonging to a bonded pool stash. This fix is based on a new
      method in the `OnStakingUpdate` traits, `on_withdraw`, which allows the
      nomination pools pallet to adjust the `TotalLockedValue` every time
      there is an implicit or explicit withdrawal from a bonded pool's stash.
      
      This PR also adds a migration that checks and updates the on-chain TVL
      if it got out of sync due to the bug this PR fixes.
      
      **Changes to `trait OnStakingUpdate`**
      
      In order for staking to notify the nomination pools pallet that chunks
      where withdrew, we add a new method, `on_withdraw` to the
      `OnStakingUpdate` trait. The nomination pools pallet filters the
      withdraws that are related to bonded pool accounts and updates the
      `TotalValueLocked` accordingly.
      
      **Others**
      - Adds try-state checks to the EPM/staking e2e tests
      - Adds tests for auto withdrawing in the context of nomination pools
      
      **To-do**
      - [x] check if we need a migration to fix the current `TotalValueLocked`
      (run try-runtime)
      - [x] migrations to fix the current on-chain TVL value

      First in a series of PRs that reduces our use of sp-std with a view to
      deprecating it.
      
      This is just looking at /substrate and moving some of the references
      from `sp-std` to `core`.
      These particular changes should be uncontroversial.
      
      Where macros are used `::core` should be used to remove any ambiguity.

      [frame] `#[pallet::composite_enum]` improved variant count handling + removed `pallet_balances`'s `MaxHolds` config (#2657)
      
      I started this investigation/issue based on @liamaharon
      
       question
      [here](https://github.com/paritytech/polkadot-sdk/pull/1801#discussion_r1410452499).
      
      ## Problem
      
      The `pallet_balances` integrity test should correctly detect that the
      runtime has correct distinct `HoldReasons` variant count. I assume the
      same situation exists for RuntimeFreezeReason.
      
      It is not a critical problem, if we set `MaxHolds` with a sufficiently
      large value, everything should be ok. However, in this case, the
      integrity_test check becomes less useful.
      
      **Situation for "any" runtime:**
      - `HoldReason` enums from different pallets:
      ```rust
              /// from pallet_nis
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		NftReceipt,
      	}
      
              /// from pallet_preimage
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		Preimage,
      	}
      
              // from pallet_state-trie-migration
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		SlashForContinueMigrate,
      		SlashForMigrateCustomTop,
      		SlashForMigrateCustomChild,
      	}
      ```
      
      - generated `RuntimeHoldReason` enum looks like:
      ```rust
      pub enum RuntimeHoldReason {
      
          #[codec(index = 32u8)]
          Preimage(pallet_preimage::HoldReason),
      
          #[codec(index = 38u8)]
          Nis(pallet_nis::HoldReason),
      
          #[codec(index = 42u8)]
          StateTrieMigration(pallet_state_trie_migration::HoldReason),
      }
      ```
      
      - composite enum `RuntimeHoldReason` variant count is detected as `3`
      - we set `type MaxHolds = ConstU32<3>`
      - `pallet_balances::integrity_test` is ok with `3`(at least 3)
      
      However, the real problem can occur in a live runtime where some
      functionality might stop working. This is due to a total of 5 distinct
      hold reasons (for pallets with multi-instance support, it is even more),
      and not all of them can be used because of an incorrect `MaxHolds`,
      which is deemed acceptable according to the `integrity_test`:
        ```
        // pseudo-code - if we try to call all of these:
      
      T::Currency::hold(&pallet_nis::HoldReason::NftReceipt.into(),
      &nft_owner, deposit)?;
      T::Currency::hold(&pallet_preimage::HoldReason::Preimage.into(),
      &nft_owner, deposit)?;
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForContinueMigrate.into(),
      &nft_owner, deposit)?;
      
        // With `type MaxHolds = ConstU32<3>` these two will fail
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomTop.into(),
      &nft_owner, deposit)?;
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomChild.into(),
      &nft_owner, deposit)?;
        ```  
      
      
      ## Solutions
      
      A macro `#[pallet::*]` expansion is extended of `VariantCount`
      implementation for the `#[pallet::composite_enum]` enum type. This
      expansion generates the `VariantCount` implementation for pallets'
      `HoldReason`, `FreezeReason`, `LockId`, and `SlashReason`. Enum variants
      must be plain enum values without fields to ensure a deterministic
      count.
      
      The composite runtime enum, `RuntimeHoldReason` and
      `RuntimeFreezeReason`, now sets `VariantCount::VARIANT_COUNT` as the sum
      of pallets' enum `VariantCount::VARIANT_COUNT`:
      ```rust
      #[frame_support::pallet(dev_mode)]
      mod module_single_instance {
      
      	#[pallet::composite_enum]
      	pub enum HoldReason {
      		ModuleSingleInstanceReason1,
      		ModuleSingleInstanceReason2,
      	}
      ...
      }
      
      #[frame_support::pallet(dev_mode)]
      mod module_multi_instance {
      
      	#[pallet::composite_enum]
      	pub enum HoldReason<I: 'static = ()> {
      		ModuleMultiInstanceReason1,
      		ModuleMultiInstanceReason2,
      		ModuleMultiInstanceReason3,
      	}
      ...
      }
      
      
      impl self::sp_api_hidden_includes_construct_runtime::hidden_include::traits::VariantCount
          for RuntimeHoldReason
      {
          const VARIANT_COUNT: u32 = 0
              + module_single_instance::HoldReason::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance1>::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance2>::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance3>::VARIANT_COUNT;
      }
      ```
      
      In addition, `MaxHolds` is removed (as suggested
      [here](https://github.com/paritytech/polkadot-sdk/pull/2657#discussion_r1443324573))
      from `pallet_balances`, and its `Holds` are now bounded to
      `RuntimeHoldReason::VARIANT_COUNT`. Therefore, there is no need to let
      the runtime specify `MaxHolds`.
      
      
      ## For reviewers
      
      Relevant changes can be found here:
      - `substrate/frame/support/procedural/src/lib.rs` 
      -  `substrate/frame/support/procedural/src/pallet/parse/composite.rs`

      [NPoS] Remove better solution threshold for unsigned submissions (#2694) · ffb2125f
      Ankan authored
      closes https://github.com/paritytech-secops/srlabs_findings/issues/78.
      
      Removes `BetterUnsignedThreshold` from pallet EPM. This will essentially
      mean any solution submitted by the validator that is strictly better
      than the current queued solution would be accepted.
      
      The reason for having these thresholds is to limit number of solutions
      submitted on-chain. However for unsigned submissions, the number of
      solutions that could be submitted on average is limited even without
      thresholding (calculation shown in the corresponding issue).

      Staking: Add `deprecate_controller_batch` AdminOrigin call (#2589) · 048a9c27
      Ross Bulat authored
      
      
      Partially Addresses #2500
      
      Adds a `deprecate_controller_batch` call to the staking pallet that is
      callable by `Root` and `StakingAdmin`. To be used for controller account
      deprecation and removed thereafter. Adds
      `MaxControllersDeprecationBatch` pallet constant that defines max
      possible deprecations per call.
      
      - [x] Add `deprecate_controller_batch` call, and
      `MaxControllersInDeprecationBatch` constant.
      - [x] Add tests, benchmark, weights. Tests that weight is only consumed
      if unique pair.
      - [x] Adds `StakingAdmin` origin to staking's `AdminOrigin` type in
      westend runtime.
      - [x] Determined that worst case 5,900 deprecations does fit into
      `maxBlock` `proofSize` and `refTime` in both normal and operational
      thresholds, meaning we can deprecate all controllers for each network in
      one call.
      
      ## Block Weights
      
      By querying `consts.system.blockWeights` we can see that the
      `deprecate_controller_batch` weights fit within the `normal` threshold
      on Polkadot.
      
      #### `controller_deprecation_batch` where i = 5900:
      #### Ref time: 69,933,325,300
      #### Proof size: 21,040,390
      
      ### Polkadot 
      
      ```
      // consts.query.blockWeights
      
      maxBlock: {
              refTime: 2,000,000,000,000
              proofSize: 18,446,744,073,709,551,615
      }
      normal: {
       maxExtrinsic: {
      	refTime: 1,479,873,955,000
      	proofSize: 13,650,590,614,545,068,195
       }
       maxTotal: {
      	refTime: 1,500,000,000,000
      	proofSize: 13,835,058,055,282,163,711
       }
      }
      ```
      
      ### Kusama

      // consts.query.blockWeights
      
        maxBlock: {
          refTime: 2,000,000,000,000
          proofSize: 18,446,744,073,709,551,615
        }

      Introduce Polkadot-Sdk `developer_hub` (#2102) · eaf1bc56
      Kian Paimani authored
      
      
      This PR introduces the new crate `developer_hub` into the polkadot-sdk
      repo. The vision for the developer-hub crate is detailed in [this
      document](https://docs.google.com/document/d/1XLLkFNE8v8HLvZpI2rzsa8N2IN1FcKntc8q-Sc4xBAk/edit?usp=sharing).
      
      <img width="1128" alt="Screenshot 2023-11-02 at 10 45 48"
      src="https://github.com/paritytech/polkadot-sdk/assets/5588131/1e12b60f-fef5-42c4-8503-a3ba234077c3">
      
      
      Other than adding the new crate, it also does the following: 
      
      * Remove the `substrate` crate, as there is now a unique umbrella crate
      for multiple things in `developer_hub::polkadot_sdk`.
      * (backport candidate) A minor change to `frame-support` macros that
      allows `T::RuntimeOrigin` to also be acceptable as the origin type.
      * (backport candidate) A minor change to `frame-system` that allows us
      to deposit events at genesis because now the real genesis config is
      generated via wasm, and we can safely assume `cfg!(feature = "std")`
      means only testing. related to #62.
      * (backport candidate) Introduces a small `read_events_for_pallet` to
      `frame_system` for easier event reading in tests.
      * From https://github.com/paritytech/polkadot-sdk-docs/issues/31, it
      takes action on improving the `pallet::call` docs.
      * From https://github.com/paritytech/polkadot-sdk-docs/issues/31, it
      takes action on improving the `UncheckedExtrinsic` docs.
      
      ## Way Forward
      
      First, a version of this is deployed temporarily
      [here](https://blog.kianenigma.nl/polkadot-sdk/developer_hub/index.html).
      I will keep it up to date on a daily basis.
      
      ### This Pull Request
      
      I see two ways forward: 
      
      1. We acknowledge that everything in `developer-hub` is going to be WIP,
      and merge this asap. We should not yet use links to this crate anywhere.
      2. We make this be the feature branch, make PRs against this, and either
      gradually backport it, or only merge to master once it is done.
      
      I am personally in favor of option 1. If we stick to option 2, we need a
      better way to deploy a staging version of this to gh-pages.
      
      ### Issue Tracking
      
      The main issues related to the future of `developer_hub` are:

      - https://github.com/paritytech/polkadot-sdk-docs/issues/4

      - [ ] create a redirect for
      https://paritytech.github.io/polkadot-sdk/master/substrate/
      - [x] analytics 
      - [ ] link checker
      - [ ] the matter of publishing, and how all of these relative links for
      when we do, that is still an open question. There is section on this in
      the landing page.

      [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,

      Ensure correct variant count in `Runtime[Hold/Freeze]Reason` (#1900) · 35eb133b

      closes https://github.com/paritytech/polkadot-sdk/issues/1882
      
      ## Breaking Changes
      
      This PR introduces a new item to `pallet_balances::Config`:
      
      ```diff
      trait Config {
      ++    type RuntimeFreezeReasons;
      }
      ```
      
      This value is only used to check it against `type MaxFreeze`. A similar
      check has been added for `MaxHolds` against `RuntimeHoldReasons`, which
      is already given to `pallet_balances`.
      
      In all contexts, you should pass the real `RuntimeFreezeReasons`
      generated by `construct_runtime` to `type RuntimeFreezeReasons`. Passing
      `()` would also work, but it would imply that the runtime uses no
      freezes at all.

      `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

      Implements a variable deposit base calculation for EPM signed submissions (#1547) · 614aa31b
      Gonçalo Pestana authored
      **Note**: This is a lift-and-shift PR from the old substrate and
      polkadot repos, both PRs have been reviewed and audited
      (https://github.com/paritytech/substrate/pull/13983,
      https://github.com/paritytech/polkadot/pull/7140)
      
      ---
      
      This PR implements a generic `BaseDeposit` calculation for signed
      submissions, based on the size of the submission queue.
      
      It adds a new associated type to EPM's config, `type SignedDepositBase`,
      that implements `Convert<usize, BalanceOf<T>>`, which is used to
      calculate the base deposit for signed submissions based on the size of
      the signed submissions queue.
      
      `struct GeometricDepositBase<Balance, Fixed, Inc>` implements the
      convert trait so that the deposit value increases as a geometric
      progression. The deposit base is calculated by `deposit_base =
      fixed_deposit_base * (1 + increase_factor)^n`, where `n` is the term of
      the progression (i.e. the number of signed submissions in the queue).
      `Fixed` and `Inc` generic params are getters for `Balance` and
      `IncreaseFactor` to compute the geometric progression. If
      `IncreaseFactor = 0`, then the signed deposit is constant and equal to
      `Fixed` regardless of the size of the queue.
      
      ### Runtime configs
      
      In Kusama, the progression with 10% increase without changing the
      current signed fixed deposit is: (term == size of the queue)
      
      Term 1: `1,333,333,332,000`
      Term 2: `1,333,333,332,000 * 1.10 = 1,466,666,665,200`
      Term 3: `1,333,333,332,000 * 1.10^2 = 1,613,333,331,200`
      Term 4: `1,333,333,332,000 * 1.10^3 = 1,774,666,664,320`
      Term 5: `1,333,333,332,000 * 1.10^4 = 1,952,133,330,752`
      Term 6: `1,333,333,332,000 * 1.10^5 = 2,147,346,663,827.20`
      Term 7: `1,333,333,332,000 * 1.10^6 = 2,362,081,330,210.92`
      Term 8: `1,333,333,332,000 * 1.10^7 = 2,598,289,463,231.01`
      Term 9: `1,333,333,332,000 * 1.10^8 = 2,858,118,409,554.11`
      Term 10: `1,333,333,332,000 * 1.10^9 = 3,143,930,250,509.52`
      
      Westend:
      
      Term 1: `2,000,000,000,000`
      Term 2: `2,000,000,000,000 * 1.10 = 2,200,000,000,000`
      Term 3: `2,000,000,000,000 * 1.10^2 = 2,420,000,000,000`
      Term 4: `2,000,000,000,000 * 1.10^3 = 2,662,000,000,000`
      Term 5: `2,000,000,000,000 * 1.10^4 = 2,928,200,000,000`
      Term 6: `2,000,000,000,000 * 1.10^5 = 3,221,020,000,000`
      Term 7: `2,000,000,000,000 * 1.10^6 = 3,543,122,000,000`
      Term 8: `2,000,000,000,000 * 1.10^7 = 3,897,434,200,000`
      Term 9: `2,000,000,000,000 * 1.10^8 = 4,287,177,620,000`
      Term 10: `2,000,000,000,000 * 1.10^9 = 4,715,895,382,000`
      
      and in Polkadot, the deposit increase is disabled in the current state
      of the PR, as the increase factor is 0% -- so nothing changes from the
      current behaviour.
