* pallet-contracts: Fix seal_restore_to to output proper module errors
Those errors where part of the decl_error for some time but where
never actually returned. This allows proper debugging of failed
restorations. Previously, any error did return the misleading
`ContractTrapped`.
* Bind UncheckedFrom<T::Hash> + AsRef<[u8]> everywhere
This allows us to make assumptions about the AccoutId
that are necessary for testing and in order to benchmark
the module properly.
This also groups free standing functions into inherent functions
in order to minimize the places where the new bounds need to
be specified.
* Rework contract address determination
* Do not allow override by runtime author
* Instantiate gained a new parameter "salt"
This change is done now in expecation of the upcoming code rent
which needs to change the instantiation dispatchable and
host function anyways.
The situation in where we have only something that is like CREATE2
makes it impossible for UIs to help the user to create an arbitrary
amount of instantiations from the same code.
With this change we have the same functionality as ethereum with
a CREATE and CREATE2 instantation semantic.
* Remove TrieIdGenerator
The new trait bounds allows us to remove this workaround
from the configuration trait.
* Remove default parameters for config trait
It should be solely the responsiblity to determine proper values for
these parameter. As a matter of fact most runtime weren't using these
values anyways.
* Fix tests for new account id type
Because of the new bounds on the trait tests can't get away by using
u64 as accound id. Replacing the 8 byte value by a 32 byte value
creates out quite a bit of code churn.
* Fix benchmarks
The benchmarks need adaption to the new instantiate semantics.
* Fix compile errors caused by adding new trait bounds
* Fix compile errors caused by renaming storage and rent functions
* Adapt host functions and dispatchables to the new salt
* Add tests for instantiate host functions (was not possible before)
* Add benchmark results
* Adapt to the new WeightInfo
The new benchmarks add a new parameter for salt "s" to the instantiate weights
that needs to be applied.
* Fix deploying_wasm_contract_should_work integration test
This test is adapted to use the new instantiate signature.
* Break overlong line
* Break more long lines

* seal: Change prefix "ext_" to "seal_" for contract callable functions
The word Ext is a overloaded term in the context of substrate. It usually
is a trait which abstracts away access to external resources usually in order
to mock them away for the purpose of tests. The contract module has its own
`Ext` trait in addition the the substrate `Ext` which makes things even more
confusing.
In order to differentiate the contract callable functions more clearly from
this `Ext` concept we rename them to use the "seal_" prefix instead.
This should change no behaviour at all. This is a pure renaming commit.
* seal: Rename import module from "env" to "seal0"
* seal: Fixup integration test
* seal: Add more tests for new import module names
* seal: Rework ext_transfer, ext_instantiate, ext_call error handling
* Deny calling plain accounts (must use transfer now)
* Return proper module error rather than ad-hoc strings
* Return the correct error codes from call,instantiate (documentation was wrong)
* Make ext_transfer fallible again to make it consistent with ext_call
* seal: Improve error messages on memory access failures
* seal: Convert contract trapped to module error
* seal: Add additional tests for transfer, call, instantiate
These tests verify that those functions return the error types
which are declared in its docs.
* Make it more pronounced that to_execution_result handles trap_reason
* Improve ReturnCode docs
* Fix whitespace issues in wat files
* Improve ReturnCode doc
* Improve ErrorOrigin doc and variant naming
* Improve docs on ExecResult and ExecError
* Encode u32 sentinel value as hex
* with_nested_context no longer accepts an Option for trie
* Fix successful typo
* Rename InvalidContractCalled to NotCallable
* Transition getter functions to not use scratch buffer
* Remove scratch buffer from ext_get_storage
* Remove scratch buffer from ext_call
* Remove scratch buffer from ext_instantiate
* Add ext_input and remove scratch buffer
* Rework error handling (changes RPC exposed data)
* ext_return passes a flags field instead of a return code
* Flags is only for seal and not for the caller
* flags: u32 replaced status_code: u8 in RPC exposed type
* API functions use a unified error type (ReturnCode)
* ext_transfer now traps on error to be consistent with call and instantiate
* Remove the no longer used `Dispatched` event
* Updated inline documentation
* Prevent skipping of copying the output for getter API
* Return gas_consumed from the RPC contracts call interface
* Updated COMPLEXTITY.md
* Rename ext_gas_price to ext_weight_to_fee
* Align comments with spaces
* Removed no longer used `ExecError`
* Remove possible panic in `from_typed_value`
* Use a struct as associated data for SpecialTrap::Return
* Fix nits in COMPLEXITY.md
* Renamed SpecialTrap to TrapReason
* Fix test
* Finish renaming special_trap -> trap_reason
* Remove no longer used get_runtime_storage
* fixup! Remove no longer used get_runtime_storage
* Removed tabs for comment aligment
