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`. -

If an XCM execution fails or ends with leftover assets, these will be trapped. In order to claim them, a custom XCM has to be executed, with the `ClaimAsset` instruction. However, arbitrary XCM execution is not allowed everywhere yet and XCM itself is still not easy enough to use for users out there with trapped assets. This new extrinsic in `pallet-xcm` will allow these users to easily claim their assets, without concerning themselves with writing arbitrary XCMs. Part of fixing https://github.com/paritytech/polkadot-sdk/issues/3495 --------- Co-authored-by: command-bot <> Co-authored-by: Adrian Catangiu <[email protected]>

Fixes #3014 This PR adds retry mechanics to `pallet-scheduler`, as described in the issue above. Users can now set a retry configuration for a task so that, in case its scheduled run fails, it will be retried after a number of blocks, for a specified number of times or until it succeeds. If a retried task runs successfully before running out of retries, its remaining retry counter will be reset to the initial value. If a retried task runs out of retries, it will be removed from the schedule. Tasks which need to be scheduled for a retry are still subject to weight metering and agenda space, same as a regular task. Periodic tasks will have their periodic schedule put on hold while the task is retrying. --------- Signed-off-by: georgepisaltu <[email protected]> Co-authored-by: command-bot <>

[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` https://github.com/paritytech/polkadot-sdk/issues/2997 . --------- Co-authored-by: command-bot <> Co-authored-by: Bastian Köcher <[email protected]> Co-authored-by: Dónal Murray <[email protected]> Co-authored-by: gupnik <[email protected]>

Adds the `authorize_upgrade` -> `enact_authorized_upgrade` pattern to `frame-system`. This will be useful for upgrading bridged chains that are under the governance of Polkadot without passing entire runtime Wasm blobs over a bridge. Notes: - Changed `enact_authorized_upgrade` to `apply_authorized_upgrade`. Personal opinion, "apply" more accurately expresses what it's doing. Can change back if outvoted. - Remove `check_version` in favor of two extrinsics, so as to make _checked_ the default. - Left calls in `parachain-system` and marked as deprecated to prevent breaking the API. They just call into the `frame-system` functions. - Updated `frame-system` benchmarks to v2 syntax. --------- Co-authored-by: command-bot <>

Treasury Pallet Instance for the Fellowship in Westend Collectives. In this update, we present a Treasury Pallet Instance that is under the control of the Fellowship body, with oversight from the Root and Treasurer origins. Here's how it is governed: - the Root origin have the authority to reject or approve spend proposals, with no amount limit for approvals. - the Treasurer origin have the authority to reject or approve spend proposals, with approval limits of up to 10,000,000 DOT. - Voice of all Fellows ranked at 3 or above can reject or approve spend proposals, with a maximum approval limit of 10,000 DOT. - Voice of Fellows ranked at 4 or above can also reject or approve spend proposals, with a maximum approval limit of 10,000,000 DOT. Additionally, we introduce the Asset Rate Pallet Instance to establish conversion rates from asset A to B. This is used to determine if a proposed spend amount involving a non-native asset is permissible by the commanding origin. The rates can be set up by the Root, Treasurer origins, or Voice of all Fellows. --------- Co-authored-by: joe petrowski <[email protected]> Co-authored-by: joepetrowski <[email protected]>

# Motivation (+testing) ### Enable easy `ForeignAssets` transfers using `pallet-xcm` We had just previously added capabilities to teleport fees during reserve-based transfers, but what about reserve-transferring fees when needing to teleport some non-fee asset? This PR aligns everything under either explicit reserve-transfer, explicit teleport, or this new flexible `transfer_assets()` which can mix and match as needed with fewer artificial constraints imposed to the user. This will enable, for example, a (non-system) parachain to teleport their `ForeignAssets` assets to AssetHub while using DOT to pay fees. (the assets are teleported - as foreign assets should from their owner chain - while DOT used for fees can only be reserve-based transferred between said parachain and AssetHub). Added `xcm-emulator` tests for this scenario ^. # Description Reverts `(limited_)reserve_transfer_assets` to only allow reserve-based transfers for all `assets` including fees. Similarly `(limited_)teleport_assets` only allows teleports for all `assets` including fees. For complex combinations of asset transfers where assets and fees may have different reserves or different reserve/teleport trust configurations, users can use the newly added `transfer_assets()` extrinsic which is more flexible in allowing more complex scenarios. `assets` (excluding `fees`) must have same reserve location or otherwise be teleportable to `dest`. No limitations imposed on `fees`. - for local reserve: transfer assets to sovereign account of destination chain and forward a notification XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. - for destination reserve: burn local assets and forward a notification to `dest` chain to withdraw the reserve assets from this chain's sovereign account and deposit them to `beneficiary`. - for remote reserve: burn local assets, forward XCM to reserve chain to move reserves from this chain's SA to `dest` chain's SA, and forward another XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. - for teleports: burn local assets and forward XCM to `dest` chain to mint/teleport assets and deposit them to `beneficiary`. ## Review notes Only around 500 lines are prod code (see `pallet_xcm/src/lib.rs`), the rest of the PR is new tests and improving existing tests. --------- Co-authored-by: command-bot <>
