Add solana-program-test compatibility test in CI

[acheroncrypto]

Problem

The expected entrypoint lifetimes in solana-program-test is not compatible with the 0.29.0 release due to the changes in #2656 but we have no tests for this case in CI.

Solution

Add a simple test to check the compatibility between anchor-lang and solana-program-test.

Hey! I'm interested in working on this issue and have explored an approach for compatibility testing in this draft PR: #2841. Does this align with the solution you had in mind?

Hey! Is there any solution? I bumped into this one type is more general than the other problem too.

@denisglotov this is a wrapper I'm using which seems to suppress the warnings. The program I'm testing is called kickjump_launchpad.

use kickjump_launchpad::ID_CONST;
use solana_program::account_info::AccountInfo;
use solana_program::entrypoint::ProgramResult;
use solana_program::pubkey::Pubkey;
use solana_program_test::processor;
use solana_program_test::ProgramTest;

pub fn add_program() -> ProgramTest {
	ProgramTest::new("kickjump_launchpad", ID_CONST, processor!(entry))
}

/// This is a wrapper to get the processor macro to work.
fn entry(program_id: &Pubkey, accounts: &[AccountInfo], instruction_data: &[u8]) -> ProgramResult {
	let accounts = Box::leak(Box::new(accounts.to_vec()));

	kickjump_launchpad::entry(program_id, accounts, instruction_data)
}

I've added the following workaround to my own codebase for testing. Would it be useful to others?

If so, I can create a pull request.

/// The current processor for [`solana_program_test`] doesn't support anchor
/// programs due to lifetime conflicts. This is a wrapper that supports the
/// anchor lifetimes by using [`Box::leak`] on the accounts array.
#[macro_export]
macro_rules! anchor_processor {
	($program:ident) => {{
		fn entry(
			program_id: &::solana_program::pubkey::Pubkey,
			accounts: &[::solana_program::account_info::AccountInfo],
			instruction_data: &[u8],
		) -> ::solana_program::entrypoint::ProgramResult {
			let accounts = Box::leak(Box::new(accounts.to_vec()));

			$program::entry(program_id, accounts, instruction_data)
		}

		::solana_program_test::processor!(entry)
	}};
}
