Detect autoloading dead locks

[nfroidure]

Dead locks can happen when autoloading and reusing a service descriptor, the following test fails:

knifecycle/src/index.mocha.js

Lines 983 to 1026 in 8079b99

	it.skip('should work when autoload depends on deeper optional and unexisting autoloaded dependencies', async () => {
	$.register(
	initializer(
	{
	type: 'service',
	name: 'log',
	inject: ['?LOG_ROUTING', '?LOGGER', '?debug'],
	},
	async () => {
	return function log() {};
	},
	),
	);
	$.register(constant('LOGGER', 'LOGGER_CONSTANT'));
	$.register(constant('debug', 'debug_value'));
	$.register(
	initializer(
	{
	type: 'service',
	name: '$autoload',
	inject: ['?ENV', '?log'],
	options: {
	singleton: true,
	},
	},
	async () => async serviceName => ({
	path: `/path/of/${serviceName}`,
	initializer: initializer(
	{
	type: 'service',
	name: serviceName,
	inject: [],
	},
	async () => `THE_${serviceName.toUpperCase()}:` + serviceName,
	),
	}),
	),
	);
	const dependencies = await $.run(['test', 'log']);
	assert.deepEqual(Object.keys(dependencies), ['test', 'log']);
	});
	});

Instead of passing an autoloading boolean, a function that checks for autoloading in all dependencies would allow to detect such situation and completely avoid dead locks.
