This PR refactors the staking ledger logic to encapsulate all reads and
mutations of `Ledger`, `Bonded`, `Payee` and stake locks within the
`StakingLedger` struct implementation.
With these changes, all the reads and mutations to the `Ledger`, `Payee`
and `Bonded` storage map should be done through the methods exposed by
StakingLedger to ensure the data and lock consistency of the operations.
The new introduced methods that mutate and read Ledger are:
- `ledger.update()`: inserts/updates a staking ledger in storage;
updates staking locks accordingly (and ledger.bond(), which is synthatic
sugar for ledger.update())
- `ledger.kill()`: removes all Bonded and StakingLedger related data for
a given ledger; updates staking locks accordingly;
`StakingLedger::get(account)`: queries both the `Bonded` and `Ledger`
storages and returns a `Option<StakingLedger>`. The pallet impl exposes
fn ledger(account) as synthatic sugar for `StakingLedger::get(account)`.
Retrieving a ledger with `StakingLedger::get()` can be done by providing
either a stash or controller account. The input must be wrapped in a
`StakingAccount` variant (Stash or Controller) which is treated
accordingly. This simplifies the caller API but will eventually be
deprecated once we completely get rid of the controller account in
staking. However, this refactor will help with the work necessary when
completely removing the controller.
Other goals:
- No logical changes have been introduced in this PR;
- No breaking changes or updates in wallets required;
- No new storage items or need to perform storage migrations;
- Centralise the changes to bonds and ledger updates to simplify the
OnStakingUpdate updates to the target list (related to
https://github.com/paritytech/polkadot-sdk/issues/443)
Note: it would be great to prevent or at least raise a warning if
`Ledger<T>`, `Payee<T>` and `Bonded<T>` storage types are accessed
outside the `StakingLedger` implementation. This PR should not get
blocked by that feature, but there's a tracking issue here
https://github.com/paritytech/polkadot-sdk/issues/149
Related and step towards

Could potentially be helpful to preserving caches when applicable, as
discussed in #685

closes#622
Pros:
* simpler interface, just functions:
`create_runtime_from_artifact_bytes()` and `execute_artifact()`
Cons:
* extra overhead of constructing executor semantics each time
I could make it a combination of
* `create_runtime_config(params)` (such that we could clone the
constructed semantics)
* `create_runtime(blob, config)`
* `execute_artifact(blob, config, params)`
Not sure if it's worth it though.

# Description
In a couple of cases, there were links pointing to the w3f github pages
domain. In other instances, there were links pointing to the old
polkadot repo's github pages. Both of these are now pointing to the
relevant links in
https://paritytech.github.io/polkadot-sdk/book/index.html.
These changes were made specifically because the w3f github pages
returns a 404, and while fixing the links, the old polkadot repo links
were touched up as well even if they do redirect properly.
This shouldn't affect anything as these are documentation link changes
only.
This pr resolves https://github.com/paritytech/polkadot-sdk/issues/1428.
*Added only to Kusama for now*
I did raise it
[here](https://github.com/polkadot-fellows/runtimes/pull/19) and we
discussed creating a chopsticks test to run an end-to-end test
however, to do that I will need a build agent/custom runner that is
powerful enough to run the build
I will be doing that separately as I still think having chopsticks test
your runtime with each commit will be very powerful and extremely useful
for the ecosystem
For now I have used XCM simulator and replicated what the other reserve
tests do

# Description
Update the DNS name of bootnodes to unify the deployment.
Each bootnode have 3 port exposed: `30333, 30334, 443`. Before, we had
different DNS names for `30333, 30334` and `443` ports. It may confuse
people and give the impression that it is two different nodes. Fixing it
by using a single domain for all
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

# Description
## Summary
Previously, the `pallet_xcm::do_reserve_transfer_assets` and
`pallet_xcm::do_teleport_assets` functions relied on weight estimation
for remote chain execution, which was based on guesswork derived from
the local chain. This approach led to complications for runtimes that
did not provide or support specific [XCM
configurations](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76ef8fd2aabf9f07de0156941ce3ed44b0/polkadot/xcm/xcm-executor/src/config.rs#L43-L47)
for `IsReserve` or `IsTeleporter`. Consequently, such runtimes had to
resort to implementing hard-coded weights for XCM instructions like
`reserve_asset_deposited` or `receive_teleported_asset` to support
extrinsics such as `pallet_xcm::reserve_transfer_assets` and
`pallet_xcm::teleport_assets`, which depended on remote weight
estimation.
The issue of remote weight estimation was addressed and resolved by
[Pull Request
#1645](https://github.com/paritytech/polkadot-sdk/pull/1645), which
removed the need for remote weight estimation.
## Solution
As a continuation of this improvement, the current PR proposes further
cleanup by removing unnecessary hard-coded values and rectifying
benchmark results with `Weight::MAX` that previously used
`T::BlockWeights::get().max_block` as an override for unsupported XCM
instructions like `ReserveAssetDeposited` and `ReceiveTeleportedAsset`.
## Questions
- [x] Can we remove now also `Hardcoded till the XCM pallet is fixed`
for `deposit_asset`? E.g. for AssetHubKusama
[here](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76ef8fd2aabf9f07de0156941ce3ed44b0/cumulus/parachains/runtimes/assets/asset-hub-kusama/src/weights/xcm/mod.rs#L129-L134)
- [x] Are comments like
[this](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76ef8fd2aabf9f07de0156941ce3ed44b0/polkadot/runtime/kusama/src/weights/xcm/mod.rs#L94)
`// Kusama doesn't support ReserveAssetDeposited, so this benchmark has
a default weight` still relevant? Shouldnt be removed/changed?
## TODO
- [x] `bench bot` regenerate xcm weights for all runtimes
- [x] remove hard-coded stuff from system parachain weight files
- [ ] when merged, open `polkadot-fellow/runtimes` PR

### 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.
Moving a few pallets to the latest and greatest `derive_impl` to give it
a try.
Part of #171

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

https://github.com/paritytech/polkadot-sdk/issues/226.
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).
This pull request is removing the Kusama and Polkadot runtime crates. As
still some crates dependent on the runtime crates, this pull request is
doing some more changes.
- It removes the `hostperfcheck` CLI command. This CLI command could
compare the current node against the standard hardware by doing some
checks. Later we added the hardware benchmark feature to Substrate. This
hardware benchmark is running on every node startup and prints a warning
if the current node is too slow. This makes this CLI command a duplicate
that was also depending on the kusama runtime.
- The pull request is removing the emulated integration tests that were
requiring the Kusama or Polkadot runtime crates.
[`RococoGenesisExt`](https://github.com/paritytech/polkadot-sdk/blob/a414ea7515c9cdc81f1d12410e646afc148250e8/polkadot/node/service/src/chain_spec.rs#L152-L171)
is removed. It was the hack to allow overwriting
`EpochDurationInBlocks`. Removal of `RococGenesisExt` prevents from
manipulating the state to change the runtime constants.
Changes:
- Environment variable which controls the `time::EpochDurationInBlocks`
value was added: `ROCOCO_EPOCH_DURATION` (epoch duration will be set to
the value of env),
- `10,100,600` versions of rococo-runtime are built in CI and put into `polkadot-debug` docker image.
`rococo-runtime` building examples:
- to build runtime for `versi_staging_testnet` which had
EpochDurationInBlocks set to 100:
```
ROCOCO_EPOCH_DURATION=100 cargo build --features=fast-runtime -p
rococo-runtime
```
- to build runtime for `wococo_development`
```
ROCOCO_EPOCH_DURATION=10 cargo build --features=fast-runtime -p
rococo-runtime
```
- to build `versi-staging` chain spec:
```
ROCOCO_EPOCH_DURATION=100 cargo run -p polkadot --features=fast-runtime
-- build-spec --chain versi-staging --raw
```
- to build `wococo-dev` chain spec:
```
ROCOCO_EPOCH_DURATION=10 cargo run -p polkadot --features=fast-runtime
-- build-spec --chain wococo-dev --raw
```
It is also possible to change the epoch duration by replacing the `code` field in the chain spec with the hex dump of pre-built runtime wasm blob (because the epoch duration is hard-coded into wasm blob).

Update the HRMP pallet to use field names for Event variants to improve
metadata for a better client experience.
Event variants are now structs instead of unnamed tuples.
Partially implements Substrate issue
[9903](https://github.com/paritytech/substrate/issues/9903) which
doesn't appear to have been moved to the monorepo.
- Async-backing related primitives are stable `primitives::v6`
- Async-backing API is now part of `api_version(7)`
- It's enabled on Rococo and Westend runtimes

For tools such that is using the `Miner` it's useful to know whether a
solution was trimmed or not and also how much that was trimmed.

Closes#1372
This fixes the target directories in the polkadot readme. I verified
manually the Ubuntu based install works on a fresh cloud machine. Build
from source also worked as described.
Since #1304 landed `--dev` also works again (not on v1.1.0 though), so I
would consider the install instructions fixed.

Two old functions should be deprecated and have their code altered in
line with capabilities of XCMv2 and above.
This means we can use the proper `Unlimited` form of weight limit rather
than guessing weight from the local chain.
Refactors availability-recovery strategies to allow for easily adding
new hotpaths and failover mechanisms.
The new interface allows for chaining multiple `RecoveryStrategy`-es
together, to cleanly express the relationship between them and share
state and code where neccessary/possible:
This was done in order to aid in implementing new hotpaths like
[systematic chunks
recovery](https://github.com/paritytech/polkadot-sdk/issues/598) and
[fetching from approval
checkers](https://github.com/paritytech/polkadot-sdk/issues/575).
Thanks to this design, intermediate state can be shared between the
strategies. For example, if the systematic chunks recovery retrieved
less than the needed amount of chunks, pass them over to the next
FetchChunks strategy, which will only need to recover the remaining
number of chunks.
Draft example of how a systematic chunk recovery strategy would look:
https://github.com/paritytech/polkadot-sdk/commit/667d870bdf1470525d66c13929d5eac7249dd995
(notice how easy it was to add and reuse code)
Note that this PR doesn't itself add any new strategy, it should fully
preserve backwards compatiblity in terms of functionality. Follow-up PRs
to add new strategies will come.
This PR filters calls from the Identity pallet from all Relay Chain
runtimes as preparation to move the identity state and logic to a system
parachain within each network.
After this change is deployed to a runtime, no more changes such as
adding new sub-identities will be possible. The frozen state will be
part of the genesis state of the system chain. After the system chain
launches, the pallet and all state will be removed from each Relay
Chain.
Applications and UIs that render display information from this pallet
will need to read from the system chain when it launches.
The goal is to allow Fellowship on Collective chain to have a sovereign
account on Polkadot so that we can add it as an identity registrar. This
will allow Fellows origin to be able to provide judgements for
Fellowship members.
This currently allow any body on any parachain including non system
parachains to have sovereign account. I cannot think of any reason why
that may be an issue but let me know if I should change it to filter
only system parachains.
[This](https://gist.github.com/xlc/ec61bfa4e9f6d62da27d30141ad2c72b) is
the testing script.
Original PR: https://github.com/paritytech/polkadot/pull/7518
This pull request removes the Polkadot and Kusama native runtime from
the polkadot node. This brings some implications with it:
There are no more kusama/polkadot-dev chain specs available. We will
need to write some tooling in the fellowship repo to provide them
easily.
The try-runtime job for polkadot & kusama is not available anymore as we
don't have the dev chain specs anymore.
Certain benchmarking commands will also not work until we migrate them
to use a runtime api.
Some crates in utils are still depending on the polkadot/kusama native
runtime that will also need to be fixed.
Port of: https://github.com/paritytech/polkadot/pull/7467
Futures channels that are used by default has a side effect of
`Sender::Clone` that efficiently increases the capacity of the bounded
channel by one. This PR fixes the undesired backpressure removal that
was caused by the #1409. This issue has been discovered by @sandreim
during Versi testing and needs to be treated as critical that should not
be included in any release without this reversion.
This PR reverts the original behaviour.
In the monorepo, secrets used in the various previous repos have been
renamed into:
- `CUMULUS_DOCKERHUB_USERNAME`
- `CUMULUS_DOCKERHUB_TOKEN`
- `POLKADOT_DOCKERHUB_USERNAME`
- `POLKADOT_DOCKERHUB_TOKEN`
This PR makes those changes and remove one of the GHW that has now been
updated for the monorepo.
