Currently, anyone can registrar a code that exceeds the code size limit
when performing the upgrade from the registrar. This PR fixes that and
adds a new test to cover this.

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.

On grid distribution messages have two paths of reaching a node, so
there is the possiblity of a race when two peers send each other the
same statement around the same time. Statement local_knowledge will tell
us that the peer should have not send the statement because we sent it
to it.
Fix it by also keeping track only of the statement we received from a
given peer and penalize it only if it sends it to us more than once.
Fixes: https://github.com/paritytech/polkadot-sdk/issues/2346
Additionally, also use different Cost labels for different paths to make
it easier to debug things.

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 PR removes the configuration of subsystem benchmarks via CLI
arguments. After this, we only keep configurations only in yaml files.
It removes unnecessary code duplication
1. Benchmark results are collected in a single struct.
2. The output of the results is prettified.
3. The result struct used to save the output as a yaml and store it in
artifacts in a CI job.

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;
```

## Summary
Built on top of the tooling and ideas introduced in
https://github.com/paritytech/polkadot-sdk/pull/2528, this PR introduces
a synthetic benchmark for measuring and assessing the performance
characteristics of the approval-voting and approval-distribution
subsystems.
Currently this allows, us to simulate the behaviours of these systems
based on the following dimensions:
```
TestConfiguration:
# Test 1
- objective: !ApprovalsTest
last_considered_tranche: 89
min_coalesce: 1
max_coalesce: 6
enable_assignments_v2: true
send_till_tranche: 60
stop_when_approved: false
coalesce_tranche_diff: 12
workdir_prefix: "/tmp"
num_no_shows_per_candidate: 0
approval_distribution_expected_tof: 6.0
approval_distribution_cpu_ms: 3.0
approval_voting_cpu_ms: 4.30
n_validators: 500
n_cores: 100
n_included_candidates: 100
min_pov_size: 1120
max_pov_size: 5120
peer_bandwidth: 524288000000
bandwidth: 524288000000
latency:
min_latency:
secs: 0
nanos: 1000000
max_latency:
secs: 0
nanos: 100000000
error: 0
num_blocks: 10
```
## The approach
1. We build a real overseer with the real implementations for
approval-voting and approval-distribution subsystems.
2. For a given network size, for each validator we pre-computed all
potential assignments and approvals it would send, because this a
computation heavy operation this will be cached on a file on disk and be
re-used if the generation parameters don't change.
3. The messages will be sent accordingly to the configured parameters
and those are split into 3 main benchmarking scenarios.
## Benchmarking scenarios
### Best case scenario *approvals_throughput_best_case.yaml*
It send to the approval-distribution only the minimum required tranche
to gathered the needed_approvals, so that a candidate is approved.
### Behaviour in the presence of no-shows *approvals_no_shows.yaml*
It sends the tranche needed to approve a candidate when we have a
maximum of *num_no_shows_per_candidate* tranches with no-shows for each
candidate.
### Maximum throughput *approvals_throughput.yaml*
It sends all the tranches for each block and measures the used CPU and
necessary network bandwidth. by the approval-voting and
approval-distribution subsystem.
## How to run it
```
cargo run -p polkadot-subsystem-bench --release -- test-sequence --path polkadot/node/subsystem-bench/examples/approvals_throughput.yaml
```
## Evaluating performance
### Use the real subsystems metrics
If you follow the steps in
https://github.com/paritytech/polkadot-sdk/tree/master/polkadot/node/subsystem-bench#install-grafana
for installing locally prometheus and grafana, all real metrics for the
`approval-distribution`, `approval-voting` and overseer are available.

### Profile with pyroscope
1. Setup pyroscope following the steps in
https://github.com/paritytech/polkadot-sdk/tree/master/polkadot/node/subsystem-bench#install-pyroscope,
then run any of the benchmark scenario with `--profile` as the
arguments.
2. Open the pyroscope dashboard in grafana, e.g:

### Useful logs
1. Network bandwidth requirements:
```
Payload bytes received from peers: 503993 KiB total, 50399 KiB/block
Payload bytes sent to peers: 629971 KiB total, 62997 KiB/block
```
2. Cpu usage by the approval-distribution/approval-voting subsystems.
```
approval-distribution CPU usage 84.061s
approval-distribution CPU usage per block 8.406s
approval-voting CPU usage 96.532s
approval-voting CPU usage per block 9.653s
```
3. Time passed until a given block is approved
```
Chain selection approved after 3500 ms hash=0x0101010101010101010101010101010101010101010101010101010101010101

```
### Using benchmark to quantify improvements from
https://github.com/paritytech/polkadot-sdk/pull/1178 +
https://github.com/paritytech/polkadot-sdk/pull/1191
Using a versi-node we compare the scenarios where all new optimisations
are disabled with a scenarios where tranche0 assignments are sent in a
single message and a conservative simulation where the coalescing of
approvals gives us just 50% reduction in the number of messages we send.
Overall, what we see is a speedup of around 30-40% in the time it takes
to process the necessary messages and a 30-40% reduction in the
necessary bandwidth.

The PR contains small fixes for:
* A test `HostConfig v11` storage migration - v11 was compared with
itself instead of with `v10`.
* Outdated comment for `ClaimQueue`
* Typos
This PR addresses two issues:
- It modifies `DepositAsset`'s asset filter from `All` to
`AllCounted(1)` to prevent potentially charging excessive weight/fees.
This adjustment avoids situations where fees could be calculated based
on the count of assets, as illustrated
[here](https://github.com/paritytech/polkadot-sdk/blob/master/cumulus/parachains/runtimes/bridge-hubs/bridge-hub-rococo/src/weights/xcm/mod.rs#L38-L46).
- It encapsulates `DepositAsset` with `SetAppendix` to ensure that
`fees` are not trapped in any case. For instance, this prevents issues
when `ExportXcm::validate` encounters an error during the processing of
`ExportMessage`.

This fix aims to solve an issue in Kusama that resulted in failed
reserve asset transfers.
During multi-hop XCMs, like reserve asset transfers where the reserve is
not the sender nor the destination, but a third remote chain, the origin
is not available to pay for delivery fees out of their account directly,
so delivery fees should be paid out of transferred assets.
This commit also adds an xcm-emulator regression test that validates
this scenario is now working.

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
{

```
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`

Some more work regarding XCMv4. Two limits from v3 were not transferred
over, those are:
- The instructions limit
- The number of assets limit
Both of these are now in v4.
For some reason `AssetInstance` increased in size, don't know why CI
didn't catch that before.

Reverts paritytech/polkadot-sdk#2302. 🤦♂️ should have checked the
migration CI first.
We either need to reduce the `max_message_size` for the open HRMP
channels on the failing chains or increase the `PageSize` of the XCMP
queue.
Both would be fine on a test-net, but i assume this will also fail
before the next SP runtime upgrade so first need to think what best to
do.
AFAIK its not possible currently to change the `max_message_size` of an
open HRMP channel.
Candidate validation has a lot of operations that are cpu bound on its
main loop things, like:
```
validation_code.hash()
sp_maybe_compressed_blob::decompress(
&validation_code.0,
VALIDATION_CODE_BOMB_LIMIT,
)
sp_maybe_compressed_blob::decompress(&pov.block_data.0, POV_BOMB_LIMIT)
let code_hash = sp_crypto_hashing::blake2_256(&code).into();
```
When you add all that you for large POV and CODE it is going to take in
the order of 10s of ms and because these are cpu bound operation it is
going to hog the executor thread and negatively affect other subsystems
around it, so it is better to just move the subsystem on the blocking
pool to make sure such unexpected behaviour is avoided.
Note! In practice this subsystem does not have a high number of work to
be done, so probably the impact of it is really low, but better safe
than sorry.

Remove `without_storage_info` from the XCMP queue pallet. Part of
https://github.com/paritytech/polkadot-sdk/issues/323
Changes:
- Limit the number of channels that can be suspended at the same time.
- Limit the number of channels that can have messages or signals pending
at the same time.
A No-OP migration is put in place to ensure that all `BoundedVec`s still
decode and not truncate after upgrade. The storage version is thereby
bumped to 4 to have our tooling remind us to deploy that migration.

Currently, collators and their alongside nodes spin up a full-scale
overseer running a bunch of subsystems that are not needed if the node
is not a validator. That was considered to be harmless; however, we've
got problems with unused subsystems getting stalled for a reason not
currently known, resulting in the overseer exiting and bringing down the
whole node.
This PR aims to only run needed subsystems on such nodes, replacing the
rest with `DummySubsystem`.
It also enables collator-optimized availability recovery subsystem
implementation.
Partially solves #1730.
Continues the work of https://github.com/paritytech/polkadot/pull/7312.
`MultiLocation` was modified to implement serialize in no-std in that
PR, but not the assets types.
This PR does the same for assets, and this also allows to inject them in
pallets that require them in genesis.
also remove some dead code and deduplicate some error handling
the new release brings performance improvements and support for
systematic chunk recovery, needed in:
https://github.com/paritytech/polkadot-sdk/pull/1644
This PR introduces a new `NonFungibleAdapter`.
It will be useful for enabling cross-chain Coretime region transfers, as
the existing `NonFungiblesAdapter` is unsuitable for this purpose. This
is due to the fact that there is only one class of items within the
`pallet-broker`, i.e., the Coretime regions.

Introduce a new test objective : `DataAvailabilityWrite`.
The new benchmark measures the network and cpu usage of
`availability-distribution`, `biftield-distribution` and
`availability-store` subsystems from the perspective of a validator node
during the process when candidates are made available.
Additionally I refactored the networking emulation to support bandwidth
acounting and limits of incoming and outgoing requests.

Fixes: https://github.com/paritytech/polkadot-sdk/issues/2138.
Especially on restart AuthorithyDiscovery cache is not populated so we
create an invalid topology and messages won't be routed correctly for
the entire session. This PR proposes to try to fix this by updating the
topology as soon as we now the Authority/PeerId mapping, that should
impact the situation dramatically.
[This issue was hit
yesterday](https://grafana.teleport.parity.io/goto/o9q2625Sg?orgId=1),
on Westend and resulted in stalling the finality.
