Memory leak
I tried to execute the following code, and observe the potential memory leak due to the decompress operation.
`
"use strict";
let path = require("path"); const decompress = require('decompress') let fs = require("fs");
const used = process.memoryUsage();
for (let key in used) {
console.log(Memory: ${key} ${Math.round(used[key] / 1024 / 1024 * 100) / 100} MB);
}
let source = path.join(__dirname + "/example.zip"); let output = path.join(__dirname,"output")
decompress("./example.zip", "dist").then((files) => {
console.log("decompress completed")
console.log("-------------------------------")
const used = process.memoryUsage();
for (let key in used) {
console.log(Memory: ${key} ${Math.round(used[key] / 1024 / 1024 * 100) / 100} MB);
}
global.gc();
console.log("after garbage collection")
process.nextTick(function () {
console.log("after tick")
const used = process.memoryUsage();
for (let key in used) {
console.log(Memory: ${key} ${Math.round(used[key] / 1024 / 1024 * 100) / 100} MB);
}
});
setTimeout(function () {
console.log("after timeout")
const used = process.memoryUsage();
for (let key in used) {
console.log(`Memory: ${key} ${Math.round(used[key] / 1024 / 1024 * 100) / 100} MB`);
}
}, 5000);
}) `
