Improve doc for pallet macro and config macro (#4146)
Improve doc: * the pallet macro is actually referring to 2 places, for the module and for the struct placeholder but doesn't really clarify it (I should have named the latter just `pallet_struct` or something but it is a bit late) * The doc of `with_default` is a bit confusing too IMO.

Asset Conversion: Pool Account ID derivation with additional Pallet ID seed (#3250)
Introduce `PalletId` as an additional seed parameter for pool's account id derivation. The PR also introduces the `pallet_asset_conversion_ops` pallet with a call to migrate a given pool to thew new account. Additionally `fungibles::lifetime::ResetTeam` and `fungible::lifetime::Refund` traits, to facilitate the migration of pools. --------- Co-authored-by: command-bot <> |

FRAME: Unity Balance Conversion for Different IDs of Native Asset (#3659)
Introduce types to define 1:1 balance conversion for different relative
asset ids/locations of native asset.
Examples:
native asset on Asset Hub presented as `VersionedLocatableAsset` type in
the context of Relay Chain is
```
{
`location`: (0, Parachain(1000)),
`asset_id`: (1, Here),
}
```
and it's balance should be converted 1:1 by implementations of
`ConversionToAssetBalance` trait.

Update benchmarking macros (#3934)
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
```

GenesisConfig presets for runtime (#2714)
The runtime now can provide a number of predefined presets of `RuntimeGenesisConfig` struct. This presets are intended to be used in different deployments, e.g.: `local`, `staging`, etc, and should be included into the corresponding chain-specs. Having `GenesisConfig` presets in runtime allows to fully decouple node from runtime types (the problem is described in #1984). **Summary of changes:** - The `GenesisBuilder` API was adjusted to enable this functionality (and provide better naming - #150): ```rust fn preset_names() -> Vec<PresetId>; fn get_preset(id: Option<PresetId>) -> Option<serde_json::Value>; //`None` means default fn build_state(value: serde_json::Value); pub struct PresetId(Vec<u8>); ``` - **Breaking change**: Old `create_default_config` method was removed, `build_config` was renamed to `build_state`. As a consequence a node won't be able to interact with genesis config for older runtimes. The cleanup was made for sake of API simplicity. Also IMO maintaining compatibility with old API is not so crucial. - Reference implementation was provided for `substrate-test-runtime` and `rococo` runtimes. For rococo new [`genesis_configs_presets`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b97c5ff0ec4a1989da5ffd8b9f3f588e3/polkadot/runtime/rococo/src/genesis_config_presets.rs#L530) module was added and is used in `GenesisBuilder` [_presets-related_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b97c5ff0ec4a1989da5ffd8b9f3f588e3/polkadot/runtime/rococo/src/lib.rs#L2462-L2485) methods. - The `chain-spec-builder` util was also improved and allows to ([_doc_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b97c5ff0ec4a1989da5ffd8b9f3f588e3/substrate/bin/utils/chain-spec-builder/src/lib.rs#L19)): - list presets provided by given runtime (`list-presets`), - display preset or default config provided by the runtime (`display-preset`), - build chain-spec using named preset (`create ... named-preset`), - The `ChainSpecBuilder` is extended with [`with_genesis_config_preset_name`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b97c5ff0ec4a1989da5ffd8b9f3f588e3/substrate/client/chain-spec/src/chain_spec.rs#L447) method which allows to build chain-spec using named preset provided by the runtime.

migrations: prevent accidentally using unversioned migrations instead of VersionedMigration (#3835)
closes #1324 #### Problem Currently, it is possible to accidentally use inner unversioned migration instead of `VersionedMigration` since both implement `OnRuntimeUpgrade`. #### Solution With this change, we make it clear that value of `Inner` is not intended to be used directly. It is achieved by bounding `Inner` to new trait `UncheckedOnRuntimeUpgrade`, which has the same interface (except `unchecked_` prefix) as `OnRuntimeUpgrade`. #### `try-runtime` functions Since developers can implement `try-runtime` for `Inner` value in `VersionedMigration` and have custom logic for it, I added the same `try-runtime` functions to `UncheckedOnRuntimeUpgrade`. I looked for a ways to not duplicate functions, but couldn't find anything that doesn't significantly change the codebase. So I would appreciate If you have any suggestions to improve this cc @liamaharon @xlc polkadot address: 16FqwPZ8GRC5U5D4Fu7W33nA55ZXzXGWHwmbnE1eT6pxuqcT --------- Co-authored-by: Liam Aharon <liam.aharon@hotmail.com> |

Extrinsic to restore corrupt staking ledgers (#3706)
This PR adds a new extrinsic `Call::restore_ledger ` gated by `StakingAdmin` origin that restores a corrupted staking ledger. This extrinsic will be used to recover ledgers that were affected by the issue discussed in https://github.com/paritytech/polkadot-sdk/issues/3245. The extrinsic will re-write the storage items associated with a stash account provided as input parameter. The data used to reset the ledger can be either i) fetched on-chain or ii) partially/totally set by the input parameters of the call. In order to use on-chain data to restore the staking locks, we need a way to read the current lock in the balances pallet. This PR adds a `InspectLockableCurrency` trait and implements it in the pallet balances. An alternative would be to tightly couple staking with the pallet balances but that's inelegant (an example of how it would look like in [this branch](https://github.com/paritytech/polkadot-sdk/tree/gpestana/ledger-badstate-clean_tightly)). More details on the type of corruptions and corresponding fixes https://hackmd.io/DLb5jEYWSmmvqXC9ae4yRg?view#/ We verified that the `Call::restore_ledger` does fix all current corrupted ledgers in Polkadot and Kusama. You can verify it here https://hackmd.io/v-XNrEoGRpe7APR-EZGhOA. **Changes introduced** - Adds `Call::restore_ledger ` extrinsic to recover a corrupted ledger; - Adds trait `frame_support::traits::currency::InspectLockableCurrency` to allow external pallets to read current locks given an account and lock ID; - Implements the `InspectLockableCurrency` in the pallet-balances. - Adds staking locks try-runtime checks (https://github.com/paritytech/polkadot-sdk/issues/3751) **Todo** - [x] benchmark `Call::restore_ledger` - [x] throughout testing of all ledger recovering cases - [x] consider adding the staking locks try-runtime checks to this PR (https://github.com/paritytech/polkadot-sdk/issues/3751) - [x] simulate restoring all ledgers (https://hackmd.io/Dsa2tvhISNSs7zcqriTaxQ?view) in Polkadot and Kusama using chopsticks -- https://hackmd.io/v-XNrEoGRpe7APR-EZGhOA Related to https://github.com/paritytech/polkadot-sdk/issues/3245 Closes https://github.com/paritytech/polkadot-sdk/issues/3751 --------- Co-authored-by: command-bot <> |

Construct Runtime v2 (#1378)
Moved from https://github.com/paritytech/substrate/pull/14788 ---- Fixes https://github.com/paritytech/polkadot-sdk/issues/232 This PR introduces outer-macro approach for `construct_runtime` as discussed in the linked issue. It looks like the following: ```rust #[frame_support::runtime] mod runtime { #[runtime::runtime] #[runtime::derive( RuntimeCall, RuntimeEvent, RuntimeError, RuntimeOrigin, RuntimeFreezeReason, RuntimeHoldReason, RuntimeSlashReason, RuntimeLockId, RuntimeTask, )] pub struct Runtime; #[runtime::pallet_index(0)] pub type System = frame_system; #[runtime::pallet_index(1)] pub type Timestamp = pallet_timestamp; #[runtime::pallet_index(2)] pub type Aura = pallet_aura; #[runtime::pallet_index(3)] pub type Grandpa = pallet_grandpa; #[runtime::pallet_index(4)] pub type Balances = pallet_balances; #[runtime::pallet_index(5)] pub type TransactionPayment = pallet_transaction_payment; #[runtime::pallet_index(6)] pub type Sudo = pallet_sudo; // Include the custom logic from the pallet-template in the runtime. #[runtime::pallet_index(7)] pub type TemplateModule = pallet_template; } ``` ## Features - `#[runtime::runtime]` attached to a struct defines the main runtime - `#[runtime::derive]` attached to this struct defines the types generated by runtime - `#[runtime::pallet_index]` must be attached to a pallet to define its index - `#[runtime::disable_call]` can be optionally attached to a pallet to disable its calls - `#[runtime::disable_unsigned]` can be optionally attached to a pallet to disable unsigned calls - A pallet instance can be defined as `TemplateModule: pallet_template<Instance>` - An optional attribute can be defined as `#[frame_support::runtime(legacy_ordering)]` to ensure that the order of hooks is same as the order of pallets (and not based on the pallet_index). This is to support legacy runtimes and should be avoided for new ones. ## Todo - [x] Update the latest syntax in kitchensink and tests - [x] Update UI tests - [x] Docs ## Extension - Abstract away the Executive similar to https://github.com/paritytech/substrate/pull/14742 - Optionally avoid the need to specify all runtime types (TBD) --------- Co-authored-by: Francisco Aguirre <franciscoaguirreperez@gmail.com> Co-authored-by: Nikhil Gupta <> |

FRAME: Create TransactionExtension as a replacement for SignedExtension (#2280)
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`. -

Multi-Block-Migrations, poll hook and new System callbacks (#1781)
This MR is the merge of https://github.com/paritytech/substrate/pull/14414 and https://github.com/paritytech/substrate/pull/14275. It implements [RFC#13](https://github.com/polkadot-fellows/RFCs/pull/13), closes https://github.com/paritytech/polkadot-sdk/issues/198. ----- This Merge request introduces three major topicals: 1. Multi-Block-Migrations 1. New pallet `poll` hook for periodic service work 1. Replacement hooks for `on_initialize` and `on_finalize` in cases where `poll` cannot be used and some more general changes to FRAME. The changes for each topical span over multiple crates. They are listed in topical order below. # 1.) Multi-Block-Migrations Multi-Block-Migrations are facilitated by creating `pallet_migrations` and configuring `System::Config::MultiBlockMigrator` to point to it. Executive picks this up and triggers one step of the migrations pallet per block. The chain is in lockdown mode for as long as an MBM is ongoing. Executive does this by polling `MultiBlockMigrator::ongoing` and not allowing any transaction in a block, if true. A MBM is defined through trait `SteppedMigration`. A condensed version looks like this: ```rust /// A migration that can proceed in multiple steps. pub trait SteppedMigration { type Cursor: FullCodec + MaxEncodedLen; type Identifier: FullCodec + MaxEncodedLen; fn id() -> Self::Identifier; fn max_steps() -> Option<u32>; fn step( cursor: Option<Self::Cursor>, meter: &mut WeightMeter, ) -> Result<Option<Self::Cursor>, SteppedMigrationError>; } ``` `pallet_migrations` can be configured with an aggregated tuple of these migrations. It then starts to migrate them one-by-one on the next runtime upgrade. Two things are important here: - 1. Doing another runtime upgrade while MBMs are ongoing is not a good idea and can lead to messed up state. - 2. **Pallet Migrations MUST BE CONFIGURED IN `System::Config`, otherwise it is not used.** The pallet supports an `UpgradeStatusHandler` that can be used to notify external logic of upgrade start/finish (for example to pause XCM dispatch). Error recovery is very limited in the case that a migration errors or times out (exceeds its `max_steps`). Currently the runtime dev can decide in `FailedMigrationHandler::failed` how to handle this. One follow-up would be to pair this with the `SafeMode` pallet and enact safe mode when an upgrade fails, to allow governance to rescue the chain. This is currently not possible, since governance is not `Mandatory`. ## Runtime API - `Core`: `initialize_block` now returns `ExtrinsicInclusionMode` to inform the Block Author whether they can push transactions. ### Integration Add it to your runtime implementation of `Core` and `BlockBuilder`: ```patch diff --git a/runtime/src/lib.rs b/runtime/src/lib.rs @@ impl_runtime_apis! { impl sp_block_builder::Core<Block> for Runtime { - fn initialize_block(header: &<Block as BlockT>::Header) { + fn initialize_block(header: &<Block as BlockT>::Header) -> RuntimeExecutiveMode { Executive::initialize_block(header) } ... } ``` # 2.) `poll` hook A new pallet hook is introduced: `poll`. `Poll` is intended to replace mostly all usage of `on_initialize`. The reason for this is that any code that can be called from `on_initialize` cannot be migrated through an MBM. Currently there is no way to statically check this; the implication is to use `on_initialize` as rarely as possible. Failing to do so can result in broken storage invariants. The implementation of the poll hook depends on the `Runtime API` changes that are explained above. # 3.) Hard-Deadline callbacks Three new callbacks are introduced and configured on `System::Config`: `PreInherents`, `PostInherents` and `PostTransactions`. These hooks are meant as replacement for `on_initialize` and `on_finalize` in cases where the code that runs cannot be moved to `poll`. The reason for this is to make the usage of HD-code (hard deadline) more explicit - again to prevent broken invariants by MBMs. # 4.) FRAME (general changes) ## `frame_system` pallet A new memorize storage item `InherentsApplied` is added. It is used by executive to track whether inherents have already been applied. Executive and can then execute the MBMs directly between inherents and transactions. The `Config` gets five new items: - `SingleBlockMigrations` this is the new way of configuring migrations that run in a single block. Previously they were defined as last generic argument of `Executive`. This shift is brings all central configuration about migrations closer into view of the developer (migrations that are configured in `Executive` will still work for now but is deprecated). - `MultiBlockMigrator` this can be configured to an engine that drives MBMs. One example would be the `pallet_migrations`. Note that this is only the engine; the exact MBMs are injected into the engine. - `PreInherents` a callback that executes after `on_initialize` but before inherents. - `PostInherents` a callback that executes after all inherents ran (including MBMs and `poll`). - `PostTransactions` in symmetry to `PreInherents`, this one is called before `on_finalize` but after all transactions. A sane default is to set all of these to `()`. Example diff suitable for any chain: ```patch @@ impl frame_system::Config for Test { type MaxConsumers = ConstU32<16>; + type SingleBlockMigrations = (); + type MultiBlockMigrator = (); + type PreInherents = (); + type PostInherents = (); + type PostTransactions = (); } ``` An overview of how the block execution now looks like is here. The same graph is also in the rust doc. <details><summary>Block Execution Flow</summary> <p>  </p> </details> ## Inherent Order Moved to https://github.com/paritytech/polkadot-sdk/pull/2154 --------------- ## TODO - [ ] Check that `try-runtime` still works - [ ] Ensure backwards compatibility with old Runtime APIs - [x] Consume weight correctly - [x] Cleanup --------- Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> Co-authored-by: Liam Aharon <liam.aharon@hotmail.com> Co-authored-by: Juan Girini <juangirini@gmail.com> Co-authored-by: command-bot <> Co-authored-by: Francisco Aguirre <franciscoaguirreperez@gmail.com> Co-authored-by: Gavin Wood <gavin@parity.io> Co-authored-by: Bastian Köcher <git@kchr.de> |

[FRAME] Parameters pallet (#2061)
Closes #169 Fork of the `orml-parameters-pallet` as introduced by https://github.com/open-web3-stack/open-runtime-module-library/pull/927 (cc @xlc) It greatly changes how the macros work, but keeps the pallet the same. The downside of my code is now that it does only support constant keys in the form of types, not value-bearing keys. I think this is an acceptable trade off, give that it can be used by *any* pallet without any changes. The pallet allows to dynamically set parameters that can be used in pallet configs while also restricting the updating on a per-key basis. The rust-docs contains a complete example. Changes: - Add `parameters-pallet` - Use in the kitchensink as demonstration - Add experimental attribute to define dynamic params in the runtime. - Adding a bunch of traits to `frame_support::traits::dynamic_params` that can be re-used by the ORML macros ## Example First to define the parameters in the runtime file. The syntax is very explicit about the codec index and errors if there is no. ```rust #[dynamic_params(RuntimeParameters, pallet_parameters::Parameters::<Runtime>))] pub mod dynamic_params { use super::*; #[dynamic_pallet_params] #[codec(index = 0)] pub mod storage { /// Configures the base deposit of storing some data. #[codec(index = 0)] pub static BaseDeposit: Balance = 1 * DOLLARS; /// Configures the per-byte deposit of storing some data. #[codec(index = 1)] pub static ByteDeposit: Balance = 1 * CENTS; } #[dynamic_pallet_params] #[codec(index = 1)] pub mod contracts { #[codec(index = 0)] pub static DepositPerItem: Balance = deposit(1, 0); #[codec(index = 1)] pub static DepositPerByte: Balance = deposit(0, 1); } } ``` Then the pallet is configured with the aggregate: ```rust impl pallet_parameters::Config for Runtime { type AggregratedKeyValue = RuntimeParameters; type AdminOrigin = EnsureRootWithSuccess<AccountId, ConstBool<true>>; ... } ``` And then the parameters can be used in a pallet config: ```rust impl pallet_preimage::Config for Runtime { type DepositBase = dynamic_params::storage::DepositBase; } ``` A custom origin an be defined like this: ```rust pub struct DynamicParametersManagerOrigin; impl EnsureOriginWithArg<RuntimeOrigin, RuntimeParametersKey> for DynamicParametersManagerOrigin { type Success = (); fn try_origin( origin: RuntimeOrigin, key: &RuntimeParametersKey, ) -> Result<Self::Success, RuntimeOrigin> { match key { RuntimeParametersKey::Storage(_) => { frame_system::ensure_root(origin.clone()).map_err(|_| origin)?; return Ok(()) }, RuntimeParametersKey::Contract(_) => { frame_system::ensure_root(origin.clone()).map_err(|_| origin)?; return Ok(()) }, } } #[cfg(feature = "runtime-benchmarks")] fn try_successful_origin(_key: &RuntimeParametersKey) -> Result<RuntimeOrigin, ()> { Ok(RuntimeOrigin::Root) } } ``` --------- Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> Co-authored-by: Nikhil Gupta <17176722+gupnik@users.noreply.github.com> Co-authored-by: Kian Paimani <5588131+kianenigma@users.noreply.github.com> 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 <git@kchr.de> Co-authored-by: Dónal Murray <donal.murray@parity.io> Co-authored-by: gupnik <nikhilgupta.iitk@gmail.com> |

rpc: backpressured RPC server (bump jsonrpsee 0.20) (#1313)
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 Previous attempt: https://github.com/paritytech/substrate/pull/13992 Resolves https://github.com/paritytech/polkadot-sdk/issues/748, resolves https://github.com/paritytech/polkadot-sdk/issues/627 |

Move cryptographic hashing procedures to crypto folder. (#2306)
Step towards https://github.com/paritytech/polkadot-sdk/issues/1975 As reported https://github.com/paritytech/polkadot-sdk/issues/1975#issuecomment-1774534225 I'd like to encapsulate crypto related stuff in a dedicated folder. Currently all cryptographic primitive wrappers are all sparsed in `substrate/core` which contains "misc core" stuff. To simplify the process, as the first step with this PR I propose to move the cryptographic hashing there. The `substrate/crypto` folder was already created to contains `ec-utils` crate. Notes: - rename `sp-core-hashing` to `sp-crypto-hashing` - rename `sp-core-hashing-proc-macro` to `sp-crypto-hashing-proc-macro` - As the crates name is changed I took the freedom to restart fresh from version 0.1.0 for both crates --------- Co-authored-by: Robert Hambrock <roberthambrock@gmail.com> |

XCMv4 (#1230)
# Note for reviewer
Most changes are just syntax changes necessary for the new version.
Most important files should be the ones under the `xcm` folder.
# Description
Added XCMv4.
## Removed `Multi` prefix
The following types have been renamed:
- MultiLocation -> Location
- MultiAsset -> Asset
- MultiAssets -> Assets
- InteriorMultiLocation -> InteriorLocation
- MultiAssetFilter -> AssetFilter
- VersionedMultiAsset -> VersionedAsset
- WildMultiAsset -> WildAsset
- VersionedMultiLocation -> VersionedLocation
In order to fix a name conflict, the `Assets` in `xcm-executor` were
renamed to `HoldingAssets`, as they represent assets in holding.
## Removed `Abstract` asset id
It was not being used anywhere and this simplifies the code.
Now assets are just constructed as follows:
```rust
let asset: Asset = (AssetId(Location::new(1, Here)), 100u128).into();
```
No need for specifying `Concrete` anymore.
## Outcome is now a named fields struct
Instead of
```rust
pub enum Outcome {
Complete(Weight),
Incomplete(Weight, Error),
Error(Error),
}
```
we now have
```rust
pub enum Outcome {
Complete { used: Weight },
Incomplete { used: Weight, error: Error },
Error { error: Error },
}
```
## Added Reanchorable trait
Now both locations and assets implement this trait, making it easier to
reanchor both.
## New syntax for building locations and junctions
Now junctions are built using the following methods:
```rust
let location = Location {
parents: 1,
interior: [Parachain(1000), PalletInstance(50), GeneralIndex(1984)].into()
};
```
or
```rust
let location = Location::new(1, [Parachain(1000), PalletInstance(50), GeneralIndex(1984)]);
```
And they are matched like so:
```rust
match location.unpack() {
(1, [Parachain(id)]) => ...
(0, Here) => ...,
(1, [_]) => ...,
}
```
This syntax is mandatory in v4, and has been also implemented for v2 and
v3 for easier migration.
This was needed to make all sizes smaller.
# TODO
- [x] Scaffold v4
- [x] Port github.com/paritytech/polkadot/pull/7236
- [x] Remove `Multi` prefix
- [x] Remove `Abstract` asset id

Unbalanced and Balanced fungible conformance tests, and fungible fixes (#1296)
Original PR https://github.com/paritytech/substrate/pull/14655 --- Partial https://github.com/paritytech/polkadot-sdk/issues/225 - [x] Adds conformance tests for Unbalanced - [x] Adds conformance tests for Balanced - Several minor fixes to fungible default implementations and the Balances pallet - [x] `Unbalanced::decrease_balance` can reap account when `Preservation` is `Preserve` - [x] `Balanced::pair` can return pairs of imbalances which do not cancel each other out - [x] Balances pallet `active_issuance` 'underflow' - [x] Refactors the conformance test file structure to match the fungible file structure: tests for traits in regular.rs go into a test file named regular.rs, tests for traits in freezes.rs go into a test file named freezes.rs, etc. - [x] Improve doc comments - [x] Simplify macros ## Fixes ### `Unbalanced::decrease_balance` can reap account when called with `Preservation::Preserve` There is a potential issue in the default implementation of `Unbalanced::decrease_balance`. The implementation can delete an account even when it is called with `preservation: Preservation::Preserve`. This seems to contradict the documentation of `Preservation::Preserve`: ```rust /// The account may not be killed and our provider reference must remain (in the context of /// tokens, this means that the account may not be dusted). Preserve, ``` I updated `Unbalanced::decrease_balance` to return `Err(TokenError::BelowMinimum)` when a withdrawal would cause the account to be reaped and `preservation: Preservation::Preserve`. - [ ] TODO Confirm with @gavofyork that this is correct behavior Test for this behavior: https://github.com/paritytech/polkadot-sdk/blob/e5c876dd6b59e2b7dbacaa4538cb42c802db3730/substrate/frame/support/src/traits/tokens/fungible/conformance_tests/regular.rs#L912-L937 ### `Balanced::pair` returning non-canceling pairs `Balanced::pair` is supposed to create a pair of imbalances that cancel each other out. However this is not the case when the method is called with an amount greater than the total supply. In the existing default implementation, `Balanced::pair` creates a pair by first rescinding the balance, creating `Debt`, and then issuing the balance, creating `Credit`. When creating `Debt`, if the amount to create exceeds the `total_supply`, `total_supply` units of `Debt` are created *instead* of `amount` units of `Debt`. This can lead to non-canceling amount of `Credit` and `Debt` being created. To address this, I create the credit and debt directly in the method instead of calling `issue` and `rescind`. Test for this behavior: https://github.com/paritytech/polkadot-sdk/blob/e5c876dd6b59e2b7dbacaa4538cb42c802db3730/substrate/frame/support/src/traits/tokens/fungible/conformance_tests/regular.rs#L1323-L1346 ### `Balances` pallet `active_issuance` 'underflow' This PR resolves an issue in the `Balances` pallet that can lead to odd behavior of `active_issuance`. Currently, the Balances pallet doesn't check if `InactiveIssuance` remains less than or equal to `TotalIssuance` when supply is deactivated. This allows `InactiveIssuance` to be greater than `TotalIssuance`, which can result in unexpected behavior from the perspective of the fungible API. `active_issuance` is derived from `TotalIssuance.saturating_sub(InactiveIssuance)`. If an `amount` is deactivated that causes `InactiveIssuance` to become greater TotalIssuance, `active_issuance` will return 0. However once in that state, reactivating an amount will not increase `active_issuance` by the reactivated `amount` as expected. Consider this test where the last assertion would fail due to this issue: https://github.com/paritytech/polkadot-sdk/blob/e5c876dd6b59e2b7dbacaa4538cb42c802db3730/substrate/frame/support/src/traits/tokens/fungible/conformance_tests/regular.rs#L1036-L1071 To address this, I've modified the `deactivate` function to ensure `InactiveIssuance` never surpasses `TotalIssuance`. --------- Co-authored-by: Muharem <ismailov.m.h@gmail.com> |

UnionOf types for merged fungible and fungibles implementations (#2033)
Introduces `UnionOf` types, crafted to merge `fungible` and `fungibles` implementations or two `fungibles` implementations into a single type implementing `fungibles`.

[FRAME] Make MQ pallet re-entrancy safe (#2356)
Closes https://github.com/paritytech/polkadot-sdk/issues/2319 Changes: - Ensure that only `enqueue_message(s)` is callable from within the message processor. This prevents messed up storage that can currently happen when the pallet is called into recursively. - Use `H256` instead of `[u8; 32]` for clearer API. ## Details The re-entracy check is done with the `environmental` crate by adding a `with_service_mutex(f)` function that runs the closure exclusively. This works since the MQ pallet is not instantiable. --------- Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> Co-authored-by: Francisco Aguirre <franciscoaguirreperez@gmail.com> |

Introduce Polkadot-Sdk developer_hub (#2102)
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/31 - https://github.com/paritytech/polkadot-sdk-docs/issues/4 - https://github.com/paritytech/polkadot-sdk-docs/issues/26 - https://github.com/paritytech/polkadot-sdk-docs/issues/32 - https://github.com/paritytech/polkadot-sdk-docs/issues/36 ### After This Pull Request - [ ] 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.

Adds syntax for marking calls feeless (#1926)
Fixes https://github.com/paritytech/polkadot-sdk/issues/1725 This PR adds the following changes: 1. An attribute `pallet::feeless_if` that can be optionally attached to a call like so: ```rust #[pallet::feeless_if(|_origin: &OriginFor<T>, something: &u32| -> bool { *something == 0 })] pub fn do_something(origin: OriginFor<T>, something: u32) -> DispatchResult { .... } ``` The closure passed accepts references to arguments as specified in the call fn. It returns a boolean that denotes the conditions required for this call to be "feeless". 2. A signed extension `SkipCheckIfFeeless<T: SignedExtension>` that wraps a transaction payment processor such as `pallet_transaction_payment::ChargeTransactionPayment`. It checks for all calls annotated with `pallet::feeless_if` to see if the conditions are met. If so, the wrapped signed extension is not called, essentially making the call feeless. In order to use this, you can simply replace your existing signed extension that manages transaction payment like so: ```diff - pallet_transaction_payment::ChargeTransactionPayment<Runtime>, + pallet_skip_feeless_payment::SkipCheckIfFeeless< + Runtime, + pallet_transaction_payment::ChargeTransactionPayment<Runtime>, + >, ``` ### Todo - [x] Tests - [x] Docs - [x] Prdoc --------- Co-authored-by: Nikhil Gupta <> Co-authored-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> Co-authored-by: Francisco Aguirre <franciscoaguirreperez@gmail.com> Co-authored-by: Liam Aharon <liam.aharon@hotmail.com> |
