      Implementation of the new validator disabling strategy (#2226) · 988e30f1
      Tsvetomir Dimitrov authored
      Closes https://github.com/paritytech/polkadot-sdk/issues/1966,
      https://github.com/paritytech/polkadot-sdk/issues/1963 and
      https://github.com/paritytech/polkadot-sdk/issues/1962.
      
      Disabling strategy specification
      [here](https://github.com/paritytech/polkadot-sdk/pull/2955). (Updated
      13/02/2024)
      
      Implements:
      * validator disabling for a whole era instead of just a session
      * no more than 1/3 of the validators in the active set are disabled
      Removes:
      * `DisableStrategy` enum - now each validator committing an offence is
      disabled.
      * New era is not forced if too many validators are disabled.
      
      Before this PR not all offenders were disabled. A decision was made
      based on [`enum
      DisableStrategy`](https://github.com/paritytech/polkadot-sdk/blob/bbb66316/substrate/primitives/staking/src/offence.rs#L54).
      Some offenders were disabled for a whole era, some just for a session,
      some were not disabled at all.
      
      This PR changes the disabling behaviour. Now a validator committing an
      offense is disabled immediately till the end of the current era.
      
      Some implementation notes:
      * `OffendingValidators` in pallet session keeps all offenders (this is
      not changed). However its type is changed from `Vec<(u32, bool)>` to
      `Vec<u32>`. The reason is simple - each offender is getting disabled so
      the bool doesn't make sense anymore.
      * When a validator is disabled it is first added to
      `OffendingValidators` and then to `DisabledValidators`. This is done in
      [`add_offending_validator`](https://github.com/paritytech/polkadot-sdk/blob/bbb66316/substrate/frame/staking/src/slashing.rs#L325)
      from staking pallet.
      * In
      [`rotate_session`](https://github.com/paritytech/polkadot-sdk/blob/bdbe9829/substrate/frame/session/src/lib.rs#L623)
      the `end_session` also calls
      [`end_era`](https://github.com/paritytech/polkadot-sdk/blob/bbb66316/substrate/frame/staking/src/pallet/impls.rs#L490)
      when an era ends. In this case `OffendingValidators` are cleared
      **(1)**.
      * Then in
      [`rotate_session`](https://github.com/paritytech/polkadot-sdk/blob/bdbe9829/substrate/frame/session/src/lib.rs#L623)
      `DisabledValidators` are cleared **(2)**
      * And finally (still in `rotate_session`) a call to
      [`start_session`](https://github.com/paritytech/polkadot-sdk/blob/bbb66316
      
      /substrate/frame/staking/src/pallet/impls.rs#L430)
      repopulates the disabled validators **(3)**.
      * The reason for this complication is that session pallet knows nothing
      abut eras. To overcome this on each new session the disabled list is
      repopulated (points 2 and 3). Staking pallet knows when a new era starts
      so with point 1 it ensures that the offenders list is cleared.

      Fix nostd build of several crates (#4060) · 7a2c9d4a
      Oliver Tale-Yazdi authored
      
      
      Preparation for https://github.com/paritytech/polkadot-sdk/pull/3935
      
      Changes:
      - Add some `default-features = false` for the case that a crate and that
      dependency both support nostd builds.
      - Shuffle files around of some benchmarking-only crates. These
      conditionally disabled the `cfg_attr` for nostd and pulled in libstd.
      Example [here](https://github.com/ggwpez/zepter/pull/95). The actual
      logic is moved into a `inner.rs` to preserve nostd capability of the
      crate in case the benchmarking feature is disabled.
      - Add some `use sp_std::vec` where needed.
      - Remove some `optional = true` in cases where it was not optional.
      - Removed one superfluous `cfg_attr(not(feature = "std"), no_std..`.
      
      All in all this should be logical no-op.

      Update benchmarking macros (#3934) · d38f6e67
      PG Herveou authored
      
      
      Current benchmarking macro returns a closure with the captured
      benchmarked code.
      This can cause issues when the benchmarked code has complex lifetime
      requirements.
      
      This PR updates the existing macro by injecting the recording parameter
      and invoking the start / stop method around the benchmarked block
      instead of returning a closure
      
      One other added benefit is that you can write this kind of code now as
      well:
      
      ```rust
      let v;
      #[block]
      { v = func.call(); }
      dbg!(v); // or assert something on v
      ```

      Fix kusama validators getting 0 backing rewards the first session they enter the active set (#3722) · 8d0cd4ff
      Alexandru Gheorghe authored
      There is a problem in the way we update `authorithy-discovery` next keys
      and because of that nodes that enter the active set would be noticed at
      the start of the session they become active, instead of the start of the
      previous session as it was intended. This is problematic because:
      
      1. The node itself advertises its addresses on the DHT only when it
      notices it should become active on around ~10m loop, so in this case it
      would notice after it becomes active.
      2. The other nodes won't be able to detect the new nodes addresses at
      the beginning of the session, so it won't added them to the reserved
      set.
      
      With 1 + 2, we end-up in a situation where the the new node won't be
      able to properly connect to its peers because it won't be in its peers
      reserved set. Now, the nodes accept by default`MIN_GOSSIP_PEERS: usize =
      25` connections to nodes that are not in the reserved set, but given
      Kusama size(> 1000 nodes) you could easily have more than`25` new nodes
      entering the active set or simply the nodes don't have slots anymore
      because, they already have connections to peers not in the active set.
      
      In the end what the node would notice is 0 backing rewards because it
      wasn't directly connected to the peers in its backing group.
      
      ## Root-cause
      
      The flow is like this:
      1. At BAD_SESSION - 1, in `rotate_session` new nodes are added to
      QueuedKeys
      https://github.com/paritytech/polkadot-sdk/blob/02e1a7f4/substrate/frame/session/src/lib.rs#L609
      ```
       <QueuedKeys<T>>::put(queued_amalgamated.clone());
      <QueuedChanged<T>>::put(next_changed);
      ```
      2. AuthorityDiscovery::on_new_session is called with `changed` being the
      value of `<QueuedChanged<T>>:` at BAD_SESSION - **2** because it was
      saved before being updated
      https://github.com/paritytech/polkadot-sdk/blob/02e1a7f4/substrate/frame/session/src/lib.rs#L613
      3. At BAD_SESSION - 1, `AuthorityDiscovery::on_new_session` doesn't
      updated its next_keys because `changed` was false.
      4. For the entire durations of `BAD_SESSION - 1` everyone calling
      runtime api `authorities`(should return past, present and future
      authorities) won't discover the nodes that should become active .
      5. At the beginning of BAD_SESSION, all nodes discover the new nodes are
      authorities, but it is already too late because reserved_nodes are
      updated only at the beginning of the session by the `gossip-support`.
      See above why this bad.
      
      ## Fix
      Update next keys with the queued_validators at every session, not matter
      the value of `changed` this is the same way babe pallet correctly does
      it.
      https://github.com/paritytech/polkadot-sdk/blob/02e1a7f4
      
      /substrate/frame/babe/src/lib.rs#L655
      
      ## Notes
      
      - The issue doesn't reproduce with proof-authorities changes like
      `versi` because `changed` would always be true and `AuthorityDiscovery`
      correctly updates its next_keys every time.
      - Confirmed at session `37651` on kusama that this is exactly what it
      happens by looking at blocks with polkadot.js.
      
      ## TODO
      - [ ] Move versi on proof of stake and properly test before and after
      fix to confirm there is no other issue.

      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`.

      `TransactionExtension`.
        - [x] `ChargeTransactionPayment`
        - [x] `DummyExtension`
        - [x] `ChargeAssetTxPayment` (asset-tx-payment)
        - [x] `ChargeAssetTxPayment` (asset-conversion-tx-payment)

      Runtime Upgrade ref docs and Single Block Migration example pallet (#1554) · 12ce4f7d
      Liam Aharon authored
      Closes https://github.com/paritytech/polkadot-sdk-docs/issues/55
      
      - Changes 'current storage version' terminology to less ambiguous
      'in-code storage version' (suggestion by @ggwpez
      
      )
      - Adds a new example pallet `pallet-example-single-block-migrations`
      - Adds a new reference doc to replace
      https://docs.substrate.io/maintain/runtime-upgrades/ (temporarily living
      in the pallet while we wait for developer hub PR to merge)
      - Adds documentation for the `storage_alias` macro
      - Improves `trait Hooks` docs 
      - Improves `trait GetStorageVersion` docs
      - Update the suggested patterns for using `VersionedMigration`, so that
      version unchecked migrations are never exported
      - Prevents accidental usage of version unchecked migrations in runtimes
      
      https://github.com/paritytech/substrate/pull/14421#discussion_r1255467895
      - Unversioned migration code is kept inside `mod version_unchecked`,
      versioned code is kept in `pub mod versioned`
      - It is necessary to use modules to limit visibility because the inner
      migration must be `pub`. See
      https://github.com/rust-lang/rust/issues/30905 and
      
      https://internals.rust-lang.org/t/lang-team-minutes-private-in-public-rules/4504/40
      for more.
      
      ### todo
      
      - [x] move to reference docs to proper place within sdk-docs (now that
      https://github.com/paritytech/polkadot-sdk/pull/2102 is merged)
      - [x] prdoc

      [FRAME Core] remove unnecessary overrides while using derive_impl for frame_system (#3317) · b78c72cf
      Gilt0 authored
      
      
      # Description
      
      This PR removes redundant type definition from test definition config
      implementations like
      ```
      #[derive_impl(frame_system::config_preludes::TestDefaultConfig as frame_system::DefaultConfig)]
      impl frame_system::Config for Test {
          type A = A;
          ...
      }
      ```
      
      This changes avoid redundancies in the code as the macro `derive_impl`
      defines the relevant types. To implement the changes, it was a simple
      fact of running tests and making sure that the tests would still run
      while the definition would be removed.
      
      Closes #3237
      
      As a note, here is a brief account of things done from the Issue's

      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.

      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`
      -  `substrate/frame/support/procedural/src/pallet/expand/composite.rs`
      -
      `substrate/frame/support/procedural/src/construct_runtime/expand/composite_helper.rs`
      -
      `substrate/frame/support/procedural/src/construct_runtime/expand/hold_reason.rs`
      -
      `substrate/frame/support/procedural/src/construct_runtime/expand/freeze_reason.rs`
      - `substrate/frame/support/src/traits/misc.rs`
      
      And the rest of the files is just about removed `MaxHolds` from
      `pallet_balances`
      
      ## Next steps
      
      Do the same for `MaxFreezes`

      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
        }
          normal: {
            maxExtrinsic: {
              refTime: 1,479,875,294,000
              proofSize: 13,650,590,614,545,068,195

      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).

      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

      ## 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

      [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

      [here](https://github.com/paritytech/polkadot-sdk/issues/433).
      
      - ErasStakers.
      - ErasStakersClipped.
      - StakingLedger.claimed_rewards, renamed to
      StakingLedger.legacy_claimed_rewards.
      
      ### Config Changes

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