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
{
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

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.

The `parachains-common` contains a lots of constants and type
definitions which are used for `polkadot-sdk`'s testnet runtimes and
also for `polkadot-fellows`'s production [SP
runtimes](https://github.com/polkadot-fellows/runtimes/tree/main/system-parachains/constants).
This PR cleans `parachains-common` module to contain only common and
generic functionality.
Testnet-specific constants have been moved to the separate module
dedicated just for testnets:

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.
In CI jobs I see calls to `forklift clean`, which apparently does not
exist.
From CI logs:
```
1m$ forklift clean[0;m
Cargo cache management utility
Usage:
forklift [command]
Available Commands:
completion Generate the autocompletion script for the specified shell
help Help about any command
serve Run forklift coordinator server for current location

stop Stop forklift coordinator server for current location
Flags:
-c, --compression string Compression algorithm to use
Available: none, xz (default "zstd")
-h, --help help for forklift
-p, --param stringToString map of additional parameters
ex: -p S3_BUCKET_NAME=my_bucket (default [])
-s, --storage string Storage driver
Available: s3, fs (default "s3")
-v, --verbose string Available: panic, fatal, error, warn, warning, info, debug, trace (default "info")
--version version for forklift
Use "forklift [command] --help" for more information about a command.
```
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.

While including files cross crate works locally. When pushed to
crates.io each crate is seperate so the file path no longer exists.
Instead change it to a symlink, which cargo will change to a read
directory when published.
extracted useful code from #2982
This PR:
- adds test 2 for Rococo <> Westend bridge: checks that relayer doesn't
submit any extra headers while there are no any messages;
- adds test 3 for Rococo <> Westend bridge: checks that relayer doesn't
submit any extra headers when there are messages;
- fixes most of comments from #2439 (like: log names, ability to run
specify test number when calling `run-tests.sh`).
Right now of all our tests, only test 2 is working (until BHs will be
upgraded to use async backing), so you can test it with
`./bridges/zombienet/run-tests.sh --test 2` locally.
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.
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.

closes https://github.com/paritytech/parity-bridges-common/issues/2796
This partially reverts the #2439 - there are some changes (unrelated to
CI) that we still want to keep. The reason of that removal is that with
async backing enabled for Rococo AH (and for other chains in the near
future), we see a lot of issues there (because we run `14` nodes +
additional standalone process within a same container and it causes a
lot of timeouts). There's no way known to me to fix it right now, so
we're removing those tests hopefully temporarily to keep CI green
also remove some dead code and deduplicate some error handling
the new release brings performance improvements and support for
systematic chunk recovery, needed in:

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.
