[solana] Ensure window length cannot exceed checkpoint account limit

[djb15]

Is there a better way to do this?

Adding this constraint breaks a bunch of tests and enforcing it in tests would make the tests extremely expensive (from a time point of view as we need to fill up checkpoint accounts for some tests), hence the conditional compilation

debug_assert!() might be a more light-weight choice if you're just doing this in once place.

Nevermind sorry I guess you only want to assert in prod, which is different

I double-checked this and I believe you can achieve this with cargo's built-in test flag. This automatically gets set when running tests and not in production.

If you do this, you can make the change I suggested and revert the changes to Cargo.toml.

bad suggestion!
