lang: Error if account init payer account is not marked mutable

[armaniferrante]

This coincidentally works if the account is not marked mutable since the client will use the provider to pay for the transaction (and thus it is mutable). However, we should require the developer to explicitly mark these paying accounts mutable.

I'm up for giving this a spin. First time I dive into this part of Anchor though, so do you have a specific place where adding this logic would be best, maybe?

I see there seems to be constraint checks done here, but they seem limited to per-account checks (e.g. payer attribute unique per account), and I have not found an instance of cross-account check yet.

Would it make sense to add these checks here?

@losman0s are you still interesting in doing this?

If so, you can add the checks in this new function https://github.com/project-serum/anchor/blob/01ff03b09b30b974f2854dd0b0b9a958dd509622/lang/syn/src/parser/accounts/mod.rs#L40

@paul-schaaf yes, been a bit tied up the last few days but I'll get to it soon. Thanks for the update.

It should pretty much be what the error describes. You are likely init-ing an account through the init macro, but forgot to mark the payer account you specified as mut.
Even if this does not fix your issue, please post your question on Discord instead.
