* Extend `Proposer` to optionally generate a proof of the proposal * Something * Refactor sr-api to not depend on client anymore * Fix benches * Apply suggestions from code review Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * Apply suggestions from code review * Introduce new `into_storage_changes` function * Switch to runtime api for `execute_block` and don't require `H256` anywhere in the code * Put the `StorageChanges` into the `Proposal` * Move the runtime api error to its own trait * Adds `StorageTransactionCache` to the runtime api This requires that we add `type NodeBlock = ` to the `impl_runtime_apis!` macro to work around some bugs in rustc :( * Remove `type NodeBlock` and switch to a "better" hack * Start using the transaction cache from the runtime api * Make it compile * Move `InMemory` to its own file * Make all tests work again * Return block, storage_changes and proof from Blockbuilder::bake() * Make sure that we use/set `storage_changes` when possible * Add test * Fix deadlock * Remove accidentally added folders * Introduce `RecordProof` as argument type to be more explicit * Update client/src/client.rs Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * Update primitives/state-machine/src/ext.rs Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * Integrates review feedback * Remove `unsafe` usage * Update client/block-builder/src/lib.rs Co-Authored-By: Benjamin Kampmann <ben@gnunicorn.org> * Update client/src/call_executor.rs * Bump versions Co-authored-by: Tomasz Drwięga <tomusdrw@users.noreply.github.com> Co-authored-by: Benjamin Kampmann <ben.kampmann@googlemail.com>
