forAwaitEach memory leak #24
Description
The following program when run on node 8 shows unbounded memory growth. It looks to be related to nested promises and closures.
const iterall = require('iterall');
class Chirper {
[iterall.$$asyncIterator]() {
let num = 0;
return {
next() {
return Promise.resolve({ value: num++, done: false });
},
};
}
}
iterall.forAwaitEach(new Chirper(), function(value, index, iterable) {
if (index % 100000 === 0) {
console.log(value, index);
console.log(process.memoryUsage());
}
});
