This PR implements an (optional) cap of the era inflation that is
allocated to staking rewards. The remaining is minted directly into the
[`RewardRemainder`](https://github.com/paritytech/polkadot-sdk/blob/fb0fd3e62445eb2dee2b2456a0c8574d1ecdcc73/substrate/frame/staking/src/pallet/mod.rs#L160)
account, which is the treasury pot account in Polkadot and Kusama.
The staking pallet now has a percent storage item, `MaxStakersRewards`,
which defines the max percentage of the era inflation that should be
allocated to staking rewards. The remaining era inflation (i.e.
`remaining = max_era_payout - staking_payout.min(staking_payout *
MaxStakersRewards))` is minted directly into the treasury.
The `MaxStakersRewards` can be set by a privileged origin through the
`set_staking_configs` extrinsic.

This error suggests using either `unvote` or `reap_vote` calls which are
unavailable in the pallet. The only available call for this is
`remove_vote`.
EDIT: Please ignore my earlier write-up. I was able to delegate with
conviction after calling `remove_vote` on all decided proposals

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.

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)
}
}
```

The `TotalLockedValue` storage value in nomination pools pallet may get
out of sync if the staking pallet does implicit withdrawal of unlocking
chunks belonging to a bonded pool stash. This fix is based on a new
method in the `OnStakingUpdate` traits, `on_withdraw`, which allows the
nomination pools pallet to adjust the `TotalLockedValue` every time
there is an implicit or explicit withdrawal from a bonded pool's stash.
This PR also adds a migration that checks and updates the on-chain TVL
if it got out of sync due to the bug this PR fixes.
**Changes to `trait OnStakingUpdate`**
In order for staking to notify the nomination pools pallet that chunks
where withdrew, we add a new method, `on_withdraw` to the
`OnStakingUpdate` trait. The nomination pools pallet filters the
withdraws that are related to bonded pool accounts and updates the
`TotalValueLocked` accordingly.
**Others**
- Adds try-state checks to the EPM/staking e2e tests
- Adds tests for auto withdrawing in the context of nomination pools
**To-do**
- [x] check if we need a migration to fix the current `TotalValueLocked`
(run try-runtime)
- [x] migrations to fix the current on-chain TVL value
✅ **Kusama**:
```
TotalValueLocked: 99.4559 kKSM
TotalValueLocked (calculated) 99.4559 kKSM
```
⚠️ **Westend**:
```
TotalValueLocked: 18.4060 kWND
TotalValueLocked (calculated) 18.4050 kWND
```
**Polkadot**: TVL not released yet.

This is the significant step to make BEEFY client able to handle both
ECDSA and (ECDSA, BLS) type signature. The idea is having BEEFY Client
generic on crypto types makes migration to new types smoother.
This makes the BEEFY Keystore generic over AuthorityId and extends its
tests to cover the case when the AuthorityId is of type (ECDSA,
BLS12-377)

When switching from the instrumented gas metering to the wasmi gas
metering we also removed all imposed limits regarding Wasm module
internals. All those things do not interact with the host and have to be
handled by wasmi. For example, Wasmi charges additional gas for
parameters to each function because as they incur some overhead.
Back then we took the opportunity to remove the dependency on the
deprecated `parity-wasm` which was used to enforce those limits.
This PR merely removes them from the `Schedule` they aren't enforced for
a while.
Those were used for some adhoc comparison of solang vs ink! with regards
to ERC20 transfers. Not been used for a while.
Benchmarking is done here now:
[smart-bench](https://github.com/paritytech/smart-bench): Weight based
benchmark to test how much transaction actually fit into a block with
the current Weights
[schlau](https://github.com/ascjones/schlau): Time based benchmarks to
compare performance
When doing a cross contract call you can supply an optional Weight limit
for that call. If one doesn't specify the limit (setting it to 0) the
sub call will have all the remaining gas available. If one does specify
the limit we subtract that amount eagerly from the Weight meter and fail
fast if not enough `Weight` is available.
This is quite annoying because setting a fixed limit will set the
`gas_required` in the gas estimation according to the specified limit.
Even if in that dry-run the actual call didn't consume that whole
amount. It effectively discards the more precise measurement it should
have from the dry-run.
This PR changes the behaviour so that the supplied limit is an actual
limit: We do the cross contract call even if the limit is higher than
the remaining `Weight`. We then fail and roll back in the cub call in
case there is not enough weight.
This makes the weight estimation in the dry-run no longer dependent on
the weight limit supplied when doing a cross contract call.

Leases can be force set, but since `Leases` is a `StorageValue`, if a
lease misses its sale rotation in which it should expire, it can never
be cleared.
This can happen if a lease is added with an `until` timeslice that lies
in a region whose sale has already started or has passed, even if the
timeslice itself hasn't passed.
This solves that issue in a minimal way, with all expired leases being
cleaned up in each sale rotation, not just the ones that are expiring in
the coming region.

Superseeds https://github.com/paritytech/polkadot-sdk/pull/1245
This PR is a migration of the
https://github.com/paritytech/substrate/pull/14577.
The PR added associated types (`AddOrigin` & `RemoveOrigin`) to
`Config`. It allows you to decouple types and areas of responsibility,
since at the moment the same types are responsible for adding and
promoting(removing and demoting). This will improve the flexibility of
the pallet configuration.
```
/// The origin required to add a member.
type AddOrigin: EnsureOrigin<Self::RuntimeOrigin, Success = ()>;
/// The origin required to remove a member. The success value indicates the
/// maximum rank *from which* the removal may be.
type RemoveOrigin: EnsureOrigin<Self::RuntimeOrigin, Success = Rank>;
```
To achieve the backward compatibility, the users of the pallet can use
the old type via the new morph:
```
type AddOrigin = MapSuccess<Self::PromoteOrigin, Ignore>;
type RemoveOrigin = Self::DemoteOrigin;
```

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

- `substrate/frame/support/procedural/src/lib.rs`
- `substrate/frame/support/procedural/src/pallet/parse/composite.rs`

This PR removes current default for `RewardDestination`, which may cause
confusion since a ledger should not have a default reward destination:
either it has a reward destination, or something is wrong. It also
changes the `Payee`'s reward destination in storage from `ValueQuery` to
`OptionQuery`.
In addition, it adds a `try_state` check to make sure each bonded ledger
have a valid reward destination.

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

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

In addition 2 helper `fns` are introduced for chekcing if all the
wrapped storage items exist or not;
Fixes#413 ;

Part of https://github.com/paritytech/polkadot-sdk/issues/239.
Invariant
1. The number of entries in `Tips` should be equal to `Reasons`.
2. If `OpenTip.finders_fee` is true, then `OpenTip.deposit` should be
greater than zero.
3. Reasons exists for each Tip[`OpenTip.reason`], implying equal length
of storage.

In https://github.com/paritytech/polkadot-sdk/pull/2941 we found out
that the new Wasmi (register) is very effective at optimizing away
certain benchmark bytecode constructs in a way that created an unfair
advantage over Wasmi (stack) which yielded our former benchmarks to be
ineffective at properly measuring the performance impact.
This PR adjusts both affected benchmarks to fix the stated problems.
Affected are
- `instr_i64const` -> `instr_i64add`: Renamed since it now measures the
performance impact of the Wasm `i64.add` instruction with locals as
inputs and outputs. This makes it impossible for Wasmi (register) to
aggressively optimize away the entire function body (as it previously
did) but still provides a way for Wasmi (register) to shine with its
register based execution model.
- `call_with_code_per_byte`: Now uses `local.get` instead of `i32.const`
for the `if` condition which prevents Wasmi (register) to aggressively
optimizing away whole parts of the `if` creating an unfair advantage.

Using just `nightly` is too generic and can fail on different systems.
Now its fixed to the nightly version of the CI.
Another way would be to use a toolchain file, since this already assumes
`rustup`.

A bonded ledger fetched with the `StakingLedger` implementation exposes
a method `ledger.controller()` that returns the controller of the
ledger. However, that controller is computed and stored under the
`ledger.controller` field on the fly - i.e when the ledger is fetched
from storage using the `StakingLedger::get` method. The controller field
is never stored in storage.
This PR add a few more tests checks and improves the ledger try-state
checks to make sure these invariants hold true.
