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.

This PR adds tests for the `transaction_broadcast` method.
The testing needs to coordinate the following components:
- The `TestApi` marks transactions as invalid and implements
`ChainApi::validate_transaction`
- this is what dictates if a transaction is valid or not and is called
from within the `BasicPool`
- The `BasicPool` which maintains the transactions and implements
`submit_and_watch` needed by the tx broadcast to submit the transaction
- The status of the transaction pool is exposed by mocking the BasicPool
- The `ChainHeadMockClient` which mocks the
`BlockchainEvents::import_notification_stream` needed by the tx
broadcast to know to which blocks the transaction is submitted
The following changes have been added to the substrate testing to
accommodate this:
- `TestApi` gets ` remove_invalid`, counterpart to `add_invalid` to
ensure an invalid transaction can become valid again; as well as a
priority setter for extrinsics
- `BasicPool` test constructor is extended with options for the
`PoolRotator`
- this mechanism is needed because transactions are banned for 30mins
(default) after they are declared invalid
- testing bypasses this by providing a `Duration::ZERO`
### Testing Scenarios
- Capture the status of the transaction as it is normally broadcasted
- `transaction_stop` is valid while the transaction is in progress
- A future transaction is handled when the dependencies are completed
- Try to resubmit the transaction at a later block (currently invalid)
- An invalid transaction status is propagated; the transaction is marked
as temporarily banned; then the ban expires and transaction is
resubmitted

* txpool: enactment state forced update
When `tree_route` computation fails, we still need to update the
`enactment_state` to be aligned with last known finalized/best block.
We do not execute enactment phase of maintain procedure, but we do
update the state.
* error -> debug
* test added
It changes the arguments of `Backend::body` method from: `BlockId<Block>` to: `&Block::Hash`
This PR is part of BlockId::Number refactoring analysis (paritytech/substrate#11292)

* rpc/tx: Add public facing `TransactionEvent`
To circumvent the fact that serde does not allow mixing
`#[serde(tag = "event")]` with
`#[serde(tag = "event", content = "block")]`
the public facing subscription structure is serialized
and deserialized to an intermmediate representation.

* Add a new host function for reporting fatal errors
* Fix one of the wasmtime executor tests
* Have `#[runtime_interface(wasm_only)]` actually mean WASM-only, and not no_std-only
* Print out errors through `Display` instead of `Debug`
* Switch one more trait to require `Error` for its error instead of only `Debug`
* Align to review comments
* Add stale branches heads to finality notifications
Warning. Previous implementation was sending a notification for
each block between the previous (explicitly) finalized block and
the new finalized one (with an hardcoded limit of 256).
Now finality notification is sent only for the new finalized head and it
contains the hash of the new finalized head, new finalized head header,
a list of all the implicitly finalized blocks and a list of stale
branches heads (i.e. the branches heads that are not part of the
canonical chain anymore).
* Add implicitly finalized blocks list to `ChainEvent::Finalized` message
The list contains all the blocks between the previously finalized block
up to the parent of the currently finalized one, sorted by block number.
`Finalized` messages handler, part of the `MaintainedTransactionPool`
implementation for `BasicPool`, still propagate full set of finalized
blocks to the txpool by iterating over implicitly finalized blocks list.
* Rust fmt
* Greedy evaluation of `stale_heads` during finalization
* Fix outdated assumption in a comment
* Removed a test optimization that is no more relevant
The loop was there to prevent sending to
`peer.network.on_block_finalized` the full list of finalized blocks.
Now only the finalized heads are received.
* Last finalized block lookup not required anymore
* Tests for block finality notifications payloads
* Document a bit tricky condition to avoid duplicate finalization notifications
* More idiomatic way to skip an iterator entry

* Remove transaction-pool `test-helpers` feature
`test-helpers` feature is a bad idea in general, because once the feature is enabled somewhere in
the workspace, it is enabled anywhere. While removing the feature, the tests were also rewritten to
get rid off other "only test" related code.
