This PR refactors `identity/benchmarkings.rs` to use benchmarking v2.
These changes are needed to improve the readability and maintainability
of the benchmarking code. Changes were implemented using
[this](https://github.com/paritytech/polkadot-sdk/commit/9ec80090f5065ce0e3234886c43bc623e8e60d77)
commit as a guide. The logic of the benchmarks remains the same.
No known issue to backlink.
## Local Testing
To test the new benchmarks:
1. `cargo build --features runtime-benchmarks`
2. `./target/debug/polkadot benchmark pallet --steps=5 --repeat=2
--pallet=pallet_identity --extrinsic='*'`

Needs https://github.com/sam0x17/macro_magic/pull/13
The associated PR allows the export of tokens from macro_magic at the
specified path. This fixes the path issue in derive-impl. Now, we can
import the default config using the standard rust syntax:
```rust
use frame_system::config_preludes::TestDefaultConfig;
[derive_impl(TestDefaultConfig as frame_system::DefaultConfig)]
impl frame_system::DefaultConfig for Test {
//....
}
```
# Description
Upgrades `macro_magic` to 0.4.3, which introduces the ability to have
`export_tokens` use the same name as the underlying item for its
auto-generated macro name. Ultimately this will allow for better dev ux
in our derive_impl feature.

## Fixing stall
### Introduction
I experienced an apparent stall downloading state from
`https://rococo-try-runtime-node.parity-chains.parity.io:443` which was
having networking difficulties only responding to my JSONRPC requests
with 50-200KB/s of bandwidth.
This PR fixes the issue causing the stall, and generally improves
performance remote-ext when it downloads state by greatly reducing the
chances of a timeout occuring.
### Description
Introduces a new `REQUEST_DURATION_TARGET` constant and modifies
`get_storage_data_dynamic_batch_size` to
- Increase or decrease the batch size of the next request depending on
whether the elapsed time of the last request was gt or lt the target
- Reset the batch size to 1 if the request times out
This fixes an issue on slow connections that can otherwise cause
multiple timeouts and a stalled download when:
1. The batch size increases rapidly as remote-ext downloads keys with
small associated storage values
2. remote-ext tries to process a large series of subsequent keys all
with extremely large associated storage values (Rococo has a series of
keys 1-5MB large)
3. The huge storage values download for 5 minutes until the request
times out
4. The partially downloaded keys are thrown out and remote-ext tries
again with a smaller batch size, but the batch size is still far too
large and takes 5 minutes to be reduced again
5. The download will be essentially stalled for many hours while the
above step cycles
After this PR, the request size will
- Not grow as large to begin with, as it is regulated downwards as the
request duration exceeds the target
- Drop immediately to 1 if the request times out. A timeout indicates
the keys next in line to download have extremely large storage values
compared to previously downloaded keys, and we need to reset the batch
size to figure out what our new ideal batch size is. By not resetting
down to 1, we risk the next request timing out again.
## Reducing memory
As suggested by @bkchr, I adjusted `get_storage_data_dynamic_batch_size`
from being recursive to a loop which allows removing a bunch of clones
that were chewing through a lot of memory. I noticed actually it was
using up to 50GB swap previously when downloading Polkadot keys on a
slow connection, because it needed to recurse and clone a lot.
After this change it uses only ~1.5GB memory.
Adds a warning to FRAME pallets when a function argument that starts
with `_` is used in the weight formula.
This is in most cases an error since the weight witness needs to be
checked.
Example:
```rust
#[pallet::call_index(0)]
#[pallet::weight(T::SystemWeightInfo::remark(_remark.len() as u32))]
pub fn remark(_origin: OriginFor<T>, _remark: Vec<u8>) -> DispatchResultWithPostInfo {
Ok(().into())
}
```
Produces this warning:
```pre
warning: use of deprecated constant `pallet::warnings::UncheckedWeightWitness_0::_w`:
It is deprecated to not check weight witness data.
Please instead ensure that all witness data for weight calculation is checked before usage.
For more info see:
<https://github.com/paritytech/polkadot-sdk/pull/1818>
--> substrate/frame/system/src/lib.rs:424:40
|
424 | pub fn remark(_origin: OriginFor<T>, _remark: Vec<u8>) -> DispatchResultWithPostInfo {
| ^^^^^^^
|
= note: `#[warn(deprecated)]` on by default
```
Can be suppressed like this, since in this case it is legit:
```rust
#[pallet::call_index(0)]
#[pallet::weight(T::SystemWeightInfo::remark(remark.len() as u32))]
pub fn remark(_origin: OriginFor<T>, remark: Vec<u8>) -> DispatchResultWithPostInfo {
let _ = remark; // We dont need to check the weight witness.
Ok(().into())
}
```
Changes:
- Add warning on uncheded weight witness
- Respect `subkeys` limit in `System::kill_prefix`
- Fix HRMP pallet and other warnings
- Update`proc_macro_warning` dependency
- Delete random folder `substrate/src/src` 🙈
- Adding Prdoc

When retrieving the ready blocks, verify that the parent of the first
ready block is on chain. If the parent is not on chain, we are
downloading from a fork. In this case, keep downloading until we have a
parent on chain (common ancestor).

See #1345, <https://github.com/paritytech/substrate/pull/14207>.
This adds all the necessary mixnet components, and puts them together in
the "kitchen-sink" node/runtime. The components added are:
- A pallet (`frame/mixnet`). This is responsible for determining the
current mixnet session and phase, and the mixnodes to use in each
session. It provides a function that validators can call to register a
mixnode for the next session. The logic of this pallet is very similar
to that of the `im-online` pallet.
- A service (`client/mixnet`). This implements the core mixnet logic,
building on the `mixnet` crate. The service communicates with other
nodes using notifications sent over the "mixnet" protocol.
- An RPC interface. This currently only supports sending transactions
over the mixnet.

### Summary
This PR introduces new dispatchables to the treasury pallet, allowing
spends of various asset types. The enhanced features of the treasury
pallet, in conjunction with the asset-rate pallet, are set up and
enabled for Westend and Rococo.
### Westend and Rococo runtimes.
Polkadot/Kusams/Rococo Treasury can accept proposals for `spends` of
various asset kinds by specifying the asset's location and ID.
#### Treasury Instance New Dispatchables:
- `spend(AssetKind, AssetBalance, Beneficiary, Option<ValidFrom>)` -
propose and approve a spend;
- `payout(SpendIndex)` - payout an approved spend or retry a failed
payout
- `check_payment(SpendIndex)` - check the status of a payout;
- `void_spend(SpendIndex)` - void previously approved spend;
> existing spend dispatchable renamed to spend_local
in this context, the `AssetKind` parameter contains the asset's location
and it's corresponding `asset_id`, for example:
`USDT` on `AssetHub`,
``` rust
location = MultiLocation(0, X1(Parachain(1000)))
asset_id = MultiLocation(0, X2(PalletInstance(50), GeneralIndex(1984)))
```
the `Beneficiary` parameter is a `MultiLocation` in the context of the
asset's location, for example
``` rust
// the Fellowship salary pallet's location / account
FellowshipSalaryPallet = MultiLocation(1, X2(Parachain(1001), PalletInstance(64)))
// or custom `AccountId`
Alice = MultiLocation(0, AccountId32(network: None, id: [1,...]))
```
the `AssetBalance` represents the amount of the `AssetKind` to be
transferred to the `Beneficiary`. For permission checks, the asset
amount is converted to the native amount and compared against the
maximum spendable amount determined by the commanding spend origin.
the `spend` dispatchable allows for batching spends with different
`ValidFrom` arguments, enabling milestone-based spending. If the
expectations tied to an approved spend are not met, it is possible to
void the spend later using the `void_spend` dispatchable.
Asset Rate Pallet provides the conversion rate from the `AssetKind` to
the native balance.
#### Asset Rate Instance Dispatchables:
- `create(AssetKind, Rate)` - initialize a conversion rate to the native
balance for the given asset
- `update(AssetKind, Rate)` - update the conversion rate to the native
balance for the given asset
- `remove(AssetKind)` - remove an existing conversion rate to the native
balance for the given asset
the pallet's dispatchables can be executed by the Root or Treasurer
origins.
### Treasury Pallet
Treasury Pallet can accept proposals for `spends` of various asset kinds
and pay them out through the implementation of the `Pay` trait.
New Dispatchables:
- `spend(Config::AssetKind, AssetBalance, Config::Beneficiary,
Option<ValidFrom>)` - propose and approve a spend;
- `payout(SpendIndex)` - payout an approved spend or retry a failed
payout;
- `check_payment(SpendIndex)` - check the status of a payout;
- `void_spend(SpendIndex)` - void previously approved spend;
> existing spend dispatchable renamed to spend_local
The parameters' types of the `spend` dispatchable exposed via the
pallet's `Config` and allows to propose and accept a spend of a certain
amount.
An approved spend can be claimed via the `payout` within the
`Config::SpendPeriod`. Clients provide an implementation of the `Pay`
trait which can pay an asset of the `AssetKind` to the `Beneficiary` in
`AssetBalance` units.
The implementation of the Pay trait might not have an immediate final
payment status, for example if implemented over `XCM` and the actual
transfer happens on a remote chain.
The `check_status` dispatchable can be executed to update the spend's
payment state and retry the `payout` if the payment has failed.

Closes#1767
Until now the `purge-chain` command would only remove the `full`
subfolder of the db folder. However there is also the `parachains` db
that currently remains and can cause problems on node restart.
Example wiht old code:
```
polkadot purge-chain --database paritydb --base-path /tmp/some-folder
Are you sure to remove "/tmp/some-folder/chains/polkadot/paritydb/full"? [y/N]: y
"/tmp/some-folder/chains/polkadot/paritydb/full" removed.
```
In this case `/tmp/some-folder/chains/polkadot/paritydb/parachains`
would remain and might cause problem on node restart because of version
conflicts as described in #1767. After this PR the whole
`/tmp/some-folder/chains/polkadot/paritydb` folder will be deleted.
Since the hash rules of this part of the `pallet_prefix/storage_prefix`
are always fixed, we can put the runtime calculation into compile time.

Makes SPs first class citizens along with the relay chains in the
context of our CI runtime upgrade checks.
## Code changes
- Sets missing current storage version in `uniques` pallet
- Adds multisig V1 migration to run where it was missing
- Removes executed migration whos pre/post hooks were failing from
collectives runtime
- Initializes storage versions for SP pallets added after genesis
- Originally I was going to wait for
https://github.com/paritytech/polkadot-sdk/pull/1297 to be merged so
this wouldn't need to be done manually, but it doesn't seem like it'll
be merged any time soon so I've decided to set them manually to unblock
this
## CI changes
- Removed dependency of `westend` runtime upgrades being complete prior
to other ones running. I assume it is supposed to cache the
`try-runtime` build for a performance benefit, but it seems it wasn't
working. Maybe someone from the CI team can look into this or explain
why it needs to be there?
- Adds check-runtime-migration jobs for Parity asset-hubs, bridge-hubs
and contract chains
- Updated VARIABLES to accomodate the `kusama-runtime` package being
renamed to `staging-kusama-runtime` in
https://github.com/paritytech/polkadot-sdk/pull/1241
- Added `EXTRA_ARGS` variable to `check-runtime-migration`, and set
`--no-weight-warnings` to the relay chain runtime upgrade checks (relay
chains don't have weight restrictions).
Moving a few pallets to the latest and greatest `derive_impl` to give it
a try.

What does this PR do?
- Introduced the TotalValueLocked storage for nomination-pools.
- introduced a slashing api in mock.rs
- additional test for tracking a slashing event towards a pool without
sub-pools
- migration for the nomination-pools (V6 to V7) with
`VersionedMigration`
Why are these changes needed?
this is the continuation of the work by @kianenigma in this
[PR](https://github.com/paritytech/substrate/pull/13319)
How were these changes implemented and what do they affect?
- It's an extra StorageValue that's modified whenever funds flow in or
out of staking for any of the `bonded_account` of `BondedPools`
- The `PoolSlashed`event is now emitted even when no `SubPools` are
found

Derive `RuntimeDebug\Eq\PartialEq` but do not bound any generics.
This achieved by using their equivalent no bound versions:
`EqNoBound\PartialEqNoBound\RuntimeDebugNoBound`.
Deriving with `Debug`, `Eq`, and `PartialEq` for the `Debt` and `Credit`
type aliases of `Imbalance` is not feasible due to the `OnDrop` and
`OppositeOnDrop` generic types lacking implementations of the same
traits.
This absence posed challenges in testing and any scenarios that demanded
the traits implementations for the type.

Instead of fragile calculation of current balance by looking at `free
balance - ED`, Nomination Pool now freezes ED in the pool reward account
to restrict an account from going below minimum balance. This also has a
nice side effect that if ED changes, we know how much is the imbalance
in ED frozen in the pool and the current required ED. A pool operator
can diligently top up the pool with the deficit in ED or vice versa,
withdraw the excess they transferred to the pool.
## Notable changes
- New call `adjust_pool_deposit`: Allows to top up the deficit or
withdraw the excess deposited funds to the pool.
- Uses Fungible trait (instead of Currency trait). Since NP was not
doing any locking/reserving previously, no migration is needed for this.
- One time migration of freezing ED from each of the existing pools (not
very PoV friendly but fine for relay chain).
# Description
This PR introduces two changes:
- the previous `Tracing` trait has been modified to accept contract
address instead of code hash (seems to be way more convenient)
- a new trait `CallInterceptor` that allows intercepting contract calls;
in particular the default implementation for `()` will just proceed in a
standard way (after compilation optimizations, there will be no
footprint of that); however, implementing type might decide to mock
invocation and return `ExecResult` instead
Note: one might try merging `before_call` and `intercept_call`. However,
IMHO this would be bad, since it would mix two completely different
abstractions - tracing without any effects and actual intervention into
execution process.
This will unblock working on mocking contracts utility in drink and
similar tools (https://github.com/Cardinal-Cryptography/drink/issues/33)

This PR adjusts the serialized format of the the returned RuntimeVersion
in the rpc-spec-v2 methods. This is done to match the format defined
here:
https://paritytech.github.io/json-rpc-interface-spec/api/chainHead_unstable_follow.html#about-the-runtime
- ##### `apis` field as object
`apis` field of `RuntimeVersion` is now returned as an object, e.g.
```
"apis": {
"0xdf6acb689907609b": 3,
"0x37e397fc7c91f5e4": 1,
}
```
instead of
```
"apis": [
["0xdf6acb689907609b", 3],
["0x37e397fc7c91f5e4", 1],
]
```
- ##### removed `stateVersion` and `authoringVersion`
`stateVersion` and `authoringVersion` are no longer returned in the
`RuntimeVersion` JSON Object.
- ##### block index in chain head events as integer
### Related Issues
Closes: #1507Closes: #1146
### Testing Done
Adjusted existing tests to make sure data is returned in the correct
format.
This pull request is to fix the output text misalignment of `subkey
inspect` command:
(the `Network ID` line has an extra space at the end, and the `Secret
seed` line lacks a leading space)
```
[btwiuse@railway ~]$ subkey inspect '' | cat -A
Secret Key URI `` is account:$
Network ID: substrate $
Secret seed: 0xfac7959dbfe72f052e5a0c3c8d6530f202b02fd8f9f5ca3580ec8deb7797479e$
Public key (hex): 0x46ebddef8cd9bb167dc30878d7113b7e168e6f0646beffd77d69d39bad76b47a$
Account ID: 0x46ebddef8cd9bb167dc30878d7113b7e168e6f0646beffd77d69d39bad76b47a$
Public key (SS58): 5DfhGyQdFobKM8NsWvEeAKk5EQQgYe9AydgJ7rMB6E1EqRzV$
SS58 Address: 5DfhGyQdFobKM8NsWvEeAKk5EQQgYe9AydgJ7rMB6E1EqRzV$
```
The output should be in the same YAML-like format as `subkey generate`:
```
[btwiuse@railway ~]$ subkey generate | cat -A
Secret phrase: awkward eagle survey resemble novel resist modify memory pistol shed flower run$
Network ID: substrate$
Secret seed: 0x20502f79366325b7dc7620664e8844ae69d441baf6e5b571a57d3b3ff28e9586$
Public key (hex): 0x468874b9e5b6b77333fa702b9201b924d6834bf956e33e2bbe37d131134ca830$
Account ID: 0x468874b9e5b6b77333fa702b9201b924d6834bf956e33e2bbe37d131134ca830$
Public key (SS58): 5DfBkAMg5xQmsePFr3BWLZm99smiNyy9axWSgembvFgDKh9v$
SS58 Address: 5DfBkAMg5xQmsePFr3BWLZm99smiNyy9axWSgembvFgDKh9v$
```
This change will fix `subkey` as well as all binaries that embed it as
the `key` subcommand, for example: `substrate key`, `polkadot key`, etc.

The PR exposes the `rpc_methods` name in the `rpc_methods` response.
This feature is useful for servers that only forward requests to methods
that are reported by the `rpc_methods`.
Jsonrpsee exposes the available methods registered so far. Registering
the `rpc_methods` requires a closure that already stores the result. As
such, the `rpc_methods` method name is manually added to the available
methods.
Closes: https://github.com/paritytech/polkadot-sdk/issues/1627
### Testing Done
```
$> curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "rpc_methods", "params":[]}' http://localhost:9944
{"jsonrpc":"2.0","result":{"methods":["account_nextIndex",... "rpc_methods",..."unsubscribe_newHead"]},"id":1}⏎

Last week we experienced a governance attack.
Surprisingly, there was no upper limit on the tip amount.
Due to the mechanism of pallet-fragment-election, the council members
will be refreshed immediately. Attacker is easy to control the council
and give a large tip amount.
Expand `StorageNoopGuard` to be able to add extra context through a
custom error message. When the guard is triggered it panics with an
error message which can be defaulted, set on construction, or set after
it has been constructed.
Turn `StorageNoopGuard` into struct with `storage_root` and
`error_message` and added `from_error_message` constructor and
`set_error_message` setter.
Also added `new()` aliased to `default()`.
Closes#375

This PR removes some unnecessary `r#`...`#` around a string and the
corresponding comment that it was done because rustfmt wasn't working
for "some reason". It seems to work fine now and clippy prefers it this
way.

I hope it's enough to fix#1701
the only solution I found to make it happen is to put an associated type
to the `Bounded` enum as well.

This PR ensures that all storage keys under a prefix are returned by the
`chainHead_storage` method.
Before this PR, the `storage_keys` was used with just the `start_key`.
Before the pagination event was generated, the last reported key
`last_key` was saved internally.
When the pagination is resumed, the `last_key` will serve as the next
`start_key` to the `storage_keys` API.
However, this behavior does not function properly for non-prefixed
storage keys.
Entry keys `a`, `ab`, `abc` share a common prefix and therefore the `ab`
key leads to `abc`.
However, for `a`, `ab`, `aB` and `abc`, the `aB` key does not
immediately lead to `abc`.
To mitigate this, the PR saves the start key of the query, together with
the next pagination key.
Improve testing to ensure we have a key entry that doesn't share the
prefix with the descendant key.

# Description
We are recently trying to upgrade our Substrate version from
`polkadot-v0.9.43` to `polkadot-v1.0.0` and we noticed a critical issue:
all deployed contracts seem to be experiencing a `CodeNotFound` error.
After a thorough investigation, it appears that the root cause of this
issue lies in the mismatch between the storage alias of `CodeInfoOf<T>`
in the migration and its original definition.
This PR corrects the storage alias to align it with its original
definition
I am uncertain about the proper approach for adding tests to this
change. Would the team consider taking over this PR to bring it to
completion?

Follow-up to https://github.com/paritytech/substrate/pull/14306.
I hope this also showcases the important message of: **It is really not
that hard to make the examples codes in rust-docs compile, and therefore
remain correct. Please embrace this :)**
It moves the documentation of proc macros to their re-export, such that
can link other items in frame-support. This is a patter that we should
embrace for all of macro docs, and apply in PRs like
https://github.com/paritytech/substrate/pull/13987 as well.
