# Description

*Removes the deprecated `trait Store` feature from the code base*

Fixes #222

Co-authored-by: Dónal Murray <[email protected]>

As I've been dancing around this pallet for quite some time anyway, I
decided to remove getters at once. There were only a few leftovers in
tests.

Related: #3326 
CC @muraca

This fixes the behaviour of `Linear` which is the default implementation
of the `AdaptPrice` trait in the broker pallet. Previously if cores were
offered but not sold in only one sale, the price would be set to zero
and due to the logic being purely multiplicative, the price would stay
at 0 indefinitely.

This could be further paired with a configurable minimum in the broker
pallet itself, which will be a future PR.

This affects the Rococo and Westend Coretime chains, but Kusama has a
different implementation so this isn't required for the Kusama launch. I
actually thought I opened this a while ago.

This documentation guide to address an incorrect exchange rate for a
non-withdrawable pool.

## Context

Implementing `HolderOf(collection_id)` we have observed a fancy glitch
where pallet deposits event with incorrect values

### Test case 

[Observe following
extrinsic](https://assethub-polkadot.subscan.io/extrinsic/0xdc72321b7674aa209c2f194ed49bd6bd12708af103f98b5b9196e0132dcba777)

To mint in collection `51` user needs to be `HolderOf(50)`.
Therefore current user is owner of item `394` `witness_data {
owned_item: 394 }`

All checking is done correctly, storage is updated correctly

However the event which is emitted does not make semantic sense as we
updated storage for `50-394` not for `51-114`

## The fix 

This PR fixes that depositing `PalletAttributeSet` emits correct values.

This PR replaces the usage of
[secp256k](https://crates.io/crates/secp256k1) crate with
[k256](https://crates.io/crates/k256) in `core::crypto::ecdsa` for
`non-std` environments as outcome of discussion in #3448.

`secp256k1` is used in `std`, meaning that we should not affect host
performance with this PR.
`k256` is enabled in runtimes (`no-std`), and is required to proceed
with #2044.

If desirable, in future we can switch to `k256` also for `std`. That
would require some performance evaluation (e.g. for EVM chains as per
https://github.com/paritytech/polkadot-sdk/issues/3448#issuecomment-1976780391).

Currently, pool member funds cannot be unbonded if the depositor's stake
is less than `MinNominatorBond`. This usually happens after
`T::MinNominatorBond` is increased.

To fix this, the above mentioned condition is added as a case for
permissionless dispatch of `chill`. After pool is chilled, pool members
can unbond their funds since pool won't be nominating anymore.

Consequently, same check is added to `nominate` call, i.e pool can not
start nominating if it's depositor does not have `MinNominatorBond`

This PR extends the Initialized event of the chainHead_follow
subscription.

Now, the event provides multiple finalized block hashes. This
information allows clients that are disconnected, and that want to
reconnect, to not lose information about the state of the chain.

At the moment, the spec encourages servers to provide at least 1 minute
of finalized blocks (~10 blocks). The users are responsible for
unpinning these blocks at a later time. This PR tries to report at least
1 finalized block and at most 16 blocks, if they are available.

Changes:
- `QueueFootprint` gets a new field; `ready_pages` that contains the
non-overweight and not yet processed pages.
- `XCMP` queue pallet is change to use the `ready_pages` instead of
`pages` to calculate the channel suspension thresholds.

This should give the XCMP queue pallet a more correct view of when to

https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/5436619#L3319

After some discussion with @kogeler

 after the we added the rate-limit
middleware it may slow down
the rpc call timings metrics significantly because it works as follows:

1. The rate limit guard is checked when the call comes and if a slot is
available -> process the call
2. If no free spot is available then the call will be sleeping
`jitter_delay + min_time_rate_guard` then woken up and checked at most
ten times
3. If no spot is available after 10 iterations -> the call is rejected
(this may take tens of seconds)

Thus, this PR adds a label "is_rate_limited" to filter those out on the
metrics "substrate_rpc_calls_time" and "substrate_rpc_calls_finished".

I had to merge two middleware layers Metrics and RateLimit to avoid
shared state in a hacky way.

Closes #2160

First part of [Extrinsic
Horizon](https://github.com/paritytech/polkadot-sdk/issues/2415)

Introduces a new trait `TransactionExtension` to replace
`SignedExtension`. Introduce the idea of transactions which obey the
runtime's extensions and have according Extension data (né Extra data)
yet do not have hard-coded signatures.

Deprecate the terminology of "Unsigned" when used for
transactions/extrinsics owing to there now being "proper" unsigned
transactions which obey the extension framework and "old-style" unsigned
which do not. Instead we have __*General*__ for the former and
__*Bare*__ for the latter. (Ultimately, the latter will be phased out as
a type of transaction, and Bare will only be used for Inherents.)

Types of extrinsic are now therefore:
- Bare (no hardcoded signature, no Extra data; used to be known as
"Unsigned")
- Bare transactions (deprecated): Gossiped, validated with
`ValidateUnsigned` (deprecated) and the `_bare_compat` bits of
`TransactionExtension` (deprecated).
  - Inherents: Not gossiped, validated with `ProvideInherent`.
- Extended (Extra data): Gossiped, validated via `TransactionExtension`.
  - Signed transactions (with a hardcoded signature).
  - General transactions (without a hardcoded signature).

`TransactionExtension` differs from `SignedExtension` because:
- A signature on the underlying transaction may validly not be present.
- It may alter the origin during validation.
- `pre_dispatch` is renamed to `prepare` and need not contain the checks
present in `validate`.
- `validate` and `prepare` is passed an `Origin` rather than a
`AccountId`.
- `validate` may pass arbitrary information into `prepare` via a new
user-specifiable type `Val`.
- `AdditionalSigned`/`additional_signed` is renamed to
`Implicit`/`implicit`. It is encoded *for the entire transaction* and
passed in to each extension as a new argument to `validate`. This
facilitates the ability of extensions to acts as underlying crypto.

There is a new `DispatchTransaction` trait which contains only default
function impls and is impl'ed for any `TransactionExtension` impler. It
provides several utility functions which reduce some of the tedium from
using `TransactionExtension` (indeed, none of its regular functions
should now need to be called directly).

Three transaction version discriminator ("versions") are now
permissible:
- 0b000000100: Bare (used to be called "Unsigned"): contains Signature
or Extra (extension data). After bare transactions are no longer
supported, this will strictly identify an Inherents only.
- 0b100000100: Old-school "Signed" Transaction: contains Signature and
Extra (extension data).
- 0b010000100: New-school "General" Transaction: contains Extra
(extension data), but no Signature.

For the New-school General Transaction, it becomes trivial for authors
to publish extensions to the mechanism for authorizing an Origin, e.g.
through new kinds of key-signing schemes, ZK proofs, pallet state,
mutations over pre-authenticated origins or any combination of the
above.

## Code Migration

### NOW: Getting it to build

Wrap your `SignedExtension`s in `AsTransactionExtension`. This should be
accompanied by renaming your aggregate type in line with the new
terminology. E.g. Before:

```rust
/// The SignedExtension to the basic transaction logic.
pub type SignedExtra = (
	/* snip */
	MySpecialSignedExtension,
);
/// Unchecked extrinsic type as expected by this runtime.
pub type UncheckedExtrinsic =
	generic::UncheckedExtrinsic<Address, RuntimeCall, Signature, SignedExtra>;
```

After:

```rust
/// The extension to the basic transaction logic.
pub type TxExtension = (
	/* snip */
	AsTransactionExtension<MySpecialSignedExtension>,
);
/// Unchecked extrinsic type as expected by this runtime.
pub type UncheckedExtrinsic =
	generic::UncheckedExtrinsic<Address, RuntimeCall, Signature, TxExtension>;
```

You'll also need to alter any transaction building logic to add a
`.into()` to make the conversion happen. E.g. Before:

```rust
fn construct_extrinsic(
		/* snip */
) -> UncheckedExtrinsic {
	let extra: SignedExtra = (
		/* snip */
		MySpecialSignedExtension::new(/* snip */),
	);
	let payload = SignedPayload::new(call.clone(), extra.clone()).unwrap();
	let signature = payload.using_encoded(|e| sender.sign(e));
	UncheckedExtrinsic::new_signed(
		/* snip */
		Signature::Sr25519(signature),
		extra,
	)
}
```

After:

```rust
fn construct_extrinsic(
		/* snip */
) -> UncheckedExtrinsic {
	let tx_ext: TxExtension = (
		/* snip */
		MySpecialSignedExtension::new(/* snip */).into(),
	);
	let payload = SignedPayload::new(call.clone(), tx_ext.clone()).unwrap();
	let signature = payload.using_encoded(|e| sender.sign(e));
	UncheckedExtrinsic::new_signed(
		/* snip */
		Signature::Sr25519(signature),
		tx_ext,
	)
}
```

### SOON: Migrating to `TransactionExtension`

Most `SignedExtension`s can be trivially converted to become a
`TransactionExtension`. There are a few things to know.

- Instead of a single trait like `SignedExtension`, you should now
implement two traits individually: `TransactionExtensionBase` and
`TransactionExtension`.
- Weights are now a thing and must be provided via the new function `fn
weight`.

#### `TransactionExtensionBase`

This trait takes care of anything which is not dependent on types
specific to your runtime, most notably `Call`.

- `AdditionalSigned`/`additional_signed` is renamed to
`Implicit`/`implicit`.
- Weight must be returned by implementing the `weight` function. If your
extension is associated with a pallet, you'll probably want to do this
via the pallet's existing benchmarking infrastructure.

#### `TransactionExtension`

Generally:
- `pre_dispatch` is now `prepare` and you *should not reexecute the
`validate` functionality in there*!
- You don't get an account ID any more; you get an origin instead. If
you need to presume an account ID, then you can use the trait function
`AsSystemOriginSigner::as_system_origin_signer`.
- You get an additional ticket, similar to `Pre`, called `Val`. This
defines data which is passed from `validate` into `prepare`. This is
important since you should not be duplicating logic from `validate` to
`prepare`, you need a way of passing your working from the former into
the latter. This is it.
- This trait takes two type parameters: `Call` and `Context`. `Call` is
the runtime call type which used to be an associated type; you can just
move it to become a type parameter for your trait impl. `Context` is not
currently used and you can safely implement over it as an unbounded
type.
- There's no `AccountId` associated type any more. Just remove it.

Regarding `validate`:
- You get three new parameters in `validate`; all can be ignored when
migrating from `SignedExtension`.
- `validate` returns a tuple on success; the second item in the tuple is
the new ticket type `Self::Val` which gets passed in to `prepare`. If
you use any information extracted during `validate` (off-chain and
on-chain, non-mutating) in `prepare` (on-chain, mutating) then you can
pass it through with this. For the tuple's last item, just return the
`origin` argument.

Regarding `prepare`:
- This is renamed from `pre_dispatch`, but there is one change:
- FUNCTIONALITY TO VALIDATE THE TRANSACTION NEED NOT BE DUPLICATED FROM
`validate`!!
- (This is different to `SignedExtension` which was required to run the
same checks in `pre_dispatch` as in `validate`.)

Regarding `post_dispatch`:
- Since there are no unsigned transactions handled by
`TransactionExtension`, `Pre` is always defined, so the first parameter
is `Self::Pre` rather than `Option<Self::Pre>`.

If you make use of `SignedExtension::validate_unsigned` or
`SignedExtension::pre_dispatch_unsigned`, then:
- Just use the regular versions of these functions instead.
- Have your logic execute in the case that the `origin` is `None`.
- Ensure your transaction creation logic creates a General Transaction
rather than a Bare Transaction; this means having to include all
`TransactionExtension`s' data.
- `ValidateUnsigned` can still be used (for now) if you need to be able
to construct transactions which contain none of the extension data,
however these will be phased out in stage 2 of the Transactions Horizon,
so you should consider moving to an extension-centric design.

## TODO

- [x] Introduce `CheckSignature` impl of `TransactionExtension` to
ensure it's possible to have crypto be done wholly in a
`TransactionExtension`.
- [x] Deprecate `SignedExtension` and move all uses in codebase to
`TransactionExtension`.
  - [x] `ChargeTransactionPayment`
  - [x] `DummyExtension`
  - [x] `ChargeAssetTxPayment` (asset-tx-payment)
  - [x] `ChargeAssetTxPayment` (asset-conversion-tx-payment)
  - [x] `CheckWeight`
  - [x] `CheckTxVersion`
  - [x] `CheckSpecVersion`
  - [x] `CheckNonce`
  - [x] `CheckNonZeroSender`
  - [x] `CheckMortality`
  - [x] `CheckGenesis`
  - [x] `CheckOnlySudoAccount`
  - [x] `WatchDummy`
  - [x] `PrevalidateAttests`
  - [x] `GenericSignedExtension`
  - [x] `SignedExtension` (chain-polkadot-bulletin)
  - [x] `RefundSignedExtensionAdapter`
- [x] Implement `fn weight` across the board.
- [ ] Go through all pre-existing extensions which assume an account
signer and explicitly handle the possibility of another kind of origin.
- [x] `CheckNonce` should probably succeed in the case of a non-account
origin.
- [x] `CheckNonZeroSender` should succeed in the case of a non-account
origin.
- [x] `ChargeTransactionPayment` and family should fail in the case of a
non-account origin.
  - [ ] 
- [x] Fix any broken tests.

Step in https://github.com/paritytech/polkadot-sdk/issues/171

This PR removes the need to specify `as [disambiguation_path]` for cases
where the trait definition resides within the same scope as default impl
path.

For example, in the following macro invocation
```rust
#[derive_impl(frame_system::config_preludes::TestDefaultConfig as frame_system::DefaultConfig)]
impl frame_system::Config for Runtime {
   ...
}
```
the trait `DefaultConfig` lies within the `frame_system` scope and
`TestDefaultConfig` impls the `DefaultConfig` trait. Using this
information, we can compute the disambiguation path internally, thus
removing the need of an explicit specification.

In cases where the trait lies outside this scope, we would still need to
specify it explicitly, but this should take care of most (if not all)
uses of `derive_impl` within FRAME's context.

Fixes https://github.com/paritytech/polkadot-sdk/issues/3496.

This fixes an issue introduced in
https://github.com/paritytech/substrate/pull/14101, in which I removed
the `Call` enum's documentation and replaced it with a link to the
`Pallet` struct, but this also removed any docs related to call from the
metadata.

I tried to add a regression test for this, but it seems to me that this
is not possible, given that using `type-info` we only assert in type-ids
for `Call`, `Event` and `Error`. I removed some doc comments from a test
setup in `frame-support-test` to demonstrate the issue there. @jsdw do
you have any comments on this?

I also fixed a small issue in the custom html/css of `polkadot-sdk-doc`
crate, making sure it does not affect the rust-doc page of all other
crates.
