What I did

implement #3710

How I did it

How to verify it

Commit message

this commit adds a `raw_create()` builtin, which executes the
corresponding `CREATE` or `CREATE2` opcode on the provided bytes, as
well as ABI-encoding the provided arguments and appending them to the
provided initcode.

Description for the changelog

Cute Animal Picture

cyberthirst · 2024-08-12T08:32:00Z

let's also update the docs please

cyberthirst · 2024-08-13T07:25:35Z

vyper/builtins/functions.py

+            ret.append(copy_bytes(buf, bytes_data_ptr(initcode), bytecode_len, maxlen))
+
+            argbuf = add_ofst(buf, bytecode_len)
+            argslen = abi_encode(argbuf, to_encode, context, bufsz=bufsz, returns_len=True)


this reminds of something: #4202

cyberthirst · 2024-08-13T11:22:10Z

vyper/builtins/functions.py

+
+            argbuf = add_ofst(buf, bytecode_len)
+            argslen = abi_encode(argbuf, to_encode, context, bufsz=bufsz, returns_len=True)
+            total_len = add_ofst(argbuf, argslen)


i think this is wrong - isn't the length now absolute wrt 0?
shouldn't it be smth like total_len = ["sub", add_ofst(argbuf, argslen), buf]

add raw_create tests

cyberthirst · 2024-08-28T09:35:34Z

vyper/builtins/functions.py

+            bytecode_len = get_bytearray_length(initcode)
+
+            maxlen = initcode.typ.maxlen
+            ret.append(copy_bytes(buf, bytes_data_ptr(initcode), bytecode_len, maxlen))


it shouldn't be problematic that copy_bytes might pad to ceil32, right?

it might copy some dirty data, but if arguments are provided, those should overwrite it

if no args are provided, we still operate with bytecode_len which will lead to ignoring the dirty data

cyberthirst · 2024-08-28T11:20:54Z

can we please add tests for the rest of the kws?

Can we ship this PR?

pcaversaccio

I think this PR is a good opportunity to discuss the following:

How do you feel about extending the PR to include my issue here as well: #4147?
The built-in is great but to increase the overall devex, we need to bundle it with some type information feature for contracts: i.e. erc20.creation_code, erc20.runtime_code, erc20.interface_id. The creation_code information can be super useful here.

Add a test

is the target here with us?

### 🕓 Changelog Vyper has recently introduced the new `raw_create` built-in function via PR [#4204](vyperlang/vyper#4204), enabling direct contract creations using the EVM opcodes [`CREATE`](https://www.evm.codes/?fork=cancun#f0) and [`CREATE2`](https://www.evm.codes/?fork=cancun#f5). In response, this PR adds [`CREATE`](https://www.evm.codes/?fork=cancun#f0), [`CREATE2`](https://www.evm.codes/?fork=cancun#f5), and [`CREATE3`](ethereum/EIPs#3171 (i.e. without an initcode factor) utility functions to the corresponding module contracts in 🐍 snekmate. Please note that the current upper limit for the contract creation code is set to `8_192` bytes (\$2^{13}\$). ```vy from snekmate.utils import create as c1 from snekmate.utils import create2 as c2 from snekmate.utils import create3 as c3 @external @payable def deploy_create(init_code: Bytes[8_192]) -> address: return c1._deploy_create(init_code) @external @payable def deploy_create2(salt: bytes32, init_code: Bytes[8_192]) -> address: return c2._deploy_create2(salt, init_code) @external @payable def deploy_create3(salt: bytes32, init_code: Bytes[8_192]) -> address: return c3._deploy_create3(salt, init_code) ``` ### ⚠️ Breaking Changes To improve clarity and maintain consistent naming conventions, the following name changes are included in this PR: - `create_address.vy` → create.vy` - `_compute_address_rlp_self` → `_compute_create_address_self` - `_compute_address_rlp` → `_compute_create_address` - `_convert_keccak256_2_address` → `_convert_keccak256_to_address` - `create2_address.vy` → `create2.vy` - `_compute_address_self` → `_compute_create2_address_self` - `_compute_address` → `_compute_create2_address` These name changes are **not** backward-compatible and may require code updates in downstream projects. Furthermore, Solidity has released its latest version [`v0.8.30`](https://github.com/ethereum/solidity/releases/tag/v0.8.30). This PR updates the Solidity test files to align with this new version (we keep `evm_version = "cancun"`). --------- Signed-off-by: Pascal Marco Caversaccio <pascal.caversaccio@hotmail.ch>
