Is MaxGas Still Limited by Rust?

[loloicci]

There is a comment about GasLimit

wasmd/x/wasm/keeper/keeper.go

Lines 31 to 33 in bbb1669

	// MaxGas for a contract is 10 billion wasmer gas (enforced in rust to prevent overflow)
	// The limit for v0.9.3 is defined here: https://github.com/CosmWasm/cosmwasm/blob/v0.9.3/packages/vm/src/backends/singlepass.rs#L15-L23
	// (this will be increased in future releases)

But in the present version, I cannot find this parameter in cosmwasm/vm.
Is it still limited by rust?

@webmaster128 would know better.

This may have been fixed with wasmer 1.0. If so, I should remove the comment

Nice find, thank you! The value was increased from 10_000_000_000 to 0x7FFFFFFFFFFFFFFF in CosmWasm 0.10 and completely removed in CosmWasm 0.13. Now ever uint64 is a valid gas limit. The constant MaxGas should be removed completely.
