      it as it is.~~
      
      ~~**Note:** In some places the term `Overlayed` is used instead of the
      more acceptable version `Overlaid` but I also left it as it is.~~
      
      ~~**Note:** In some places the term `Applyable` is used instead of the
      correct version `Applicable` but I also left it as it is.~~
      
      **Note:** Some usage of British vs American english e.g. `judgement` vs
      `judgment`, `initialise` vs `initialize`, `optimise` vs `optimize` etc.
      are both present in different places, but I suppose that's
      understandable given the number of contributors.
      
      ~~**Note:** There is a spelling mistake in `.github/CODEOWNERS` but it
      triggers errors in CI when I make changes to it, so I left it as it
      is.~~

      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] `ChargeAssetTxPayment` (asset-conversion-tx-payment)
        - [x] `CheckWeight`
        - [x] `CheckTxVersion`
        - [x] `CheckSpecVersion`
        - [x] `CheckNonce`
        - [x] `CheckNonZeroSender`
        - [x] `CheckMortality`
        - [x] `CheckGenesis`
        - [x] `CheckOnlySudoAccount`
        - [x] `WatchDummy`
        - [x] `PrevalidateAttests`
        - [x] `GenericSignedExtension`
        - [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.

      Lifting some more dependencies to the workspace. Just using the
      most-often updated ones for now.
      It can be reproduced locally.
      
      ```sh
      # First you can check if there would be semver incompatible bumps (looks good in this case):
      $ zepter transpose dependency lift-to-workspace --ignore-errors syn quote thiserror "regex:^serde.*"
      
      # Then apply the changes:
      $ zepter transpose dependency lift-to-workspace --version-resolver=highest syn quote thiserror "regex:^serde.*" --fix
      
      # And format the changes:
      $ taplo format --config .config/taplo.toml
      ```

      rpc: backpressured RPC server (bump jsonrpsee 0.20) (#1313) · e16ef086
      Niklas Adolfsson authored
      This is a rather big change in jsonrpsee, the major things in this bump
      are:
      - Server backpressure (the subscription impls are modified to deal with
      that)
      - Allow custom error types / return types (remove jsonrpsee::core::Error
      and jsonrpee::core::CallError)
      - Bug fixes (graceful shutdown in particular not used by substrate
      anyway)
         - Less dependencies for the clients in particular
         - Return type requires Clone in method call responses
         - Moved to tokio channels
         - Async subscription API (not used in this PR)
      
      Major changes in this PR:
      - The subscriptions are now bounded and if subscription can't keep up
      with the server it is dropped
      - CLI: add parameter to configure the jsonrpc server bounded message
      buffer (default is 64)
      - Add our own subscription helper to deal with the unbounded streams in
      substrate
      
      The most important things in this PR to review is the added helpers
      functions in `substrate/client/rpc/src/utils.rs` and the rest is pretty
      much chore.
      
      Regarding the "bounded buffer limit" it may cause the server to handle
      the JSON-RPC calls
      slower than before.
      
      The message size limit is bounded by "--rpc-response-size" thus "by
      default 10MB * 64 = 640MB"
      but the subscription message size is not covered by this limit and could
      be capped as well.
      
      Hopefully the last release prior to 1.0, sorry in advance for a big PR

      `sc-block-builder`: Remove `BlockBuilderProvider` (#2099) · ca5f1056
      Bastian Köcher authored
      The `BlockBuilderProvider` was a trait that was defined in
      `sc-block-builder`. The trait was implemented for `Client`. This
      basically meant that you needed to import `sc-block-builder` any way to
      have access to the block builder. So, this trait was not providing any
      real value. This pull request is removing the said trait. Instead of the
      trait it introduces a builder for creating a `BlockBuilder`. The builder
      currently has the quite fabulous name `BlockBuilderBuilder` (I'm open to
      any better name 😅
      
      ). The rest of the pull request is about
      replacing the old trait with the new builder.
      
      # Downstream code changes
      
      If you used `new_block` or `new_block_at` before you now need to switch
      it over to the new `BlockBuilderBuilder` pattern:
      
      ```rust
      // `new` requires a type that implements `CallApiAt`. 
      let mut block_builder = BlockBuilderBuilder::new(client)
                      // Then you need to specify the hash of the parent block the block will be build on top of
      		.on_parent_block(at)
                      // The block builder also needs the block number of the parent block. 
                      // Here it is fetched from the given `client` using the `HeaderBackend`
                      // However, there also exists `with_parent_block_number` for directly passing the number
      		.fetch_parent_block_number(client)
      		.unwrap()
                      // Enable proof recording if required. This call is optional.
      		.enable_proof_recording()
                      // Pass the digests. This call is optional.
                      .with_inherent_digests(digests)
      		.build()
      		.expect("Creates new block builder");
      ```
