Corrupted unzipped files when using Extract

[marcogrcr]

I'm trying to unzip a .zip file containing chromedriver using unzipper@0.10.14. When attempting to unzip chromedriver_linux64.zip downloaded from here, the extraction succeeds, but the executable is corrupted:

$ unzip chromedriver_linux64.zip

$ md5sum chromedriver
ee3dba5202ae87d7b79c22341030db49

$ ./chromedriver
Starting ChromeDriver 111.0.5563.64 (c710e93d5b63b7095afe8c2c17df34408078439d-refs/branch-heads/5563@{#995}) on port 9515

ChromeDriver was started successfully.

import { createReadStream } from "node:fs";
import { Extract } from "unzipper";

await createReadStream("chromedriver_linux64.zip")
      .pipe(Extract({ path: "/tmp" }))
      .promise();

Then, when I run:

$ md5sum /tmp/chromedriver
641c5ede222e09e76fe52bc1bc61c0a9

$ /tmp/chromedriver
zsh: permission denied: /tmp/chromedriver

$ chmod +x /tmp/chromedriver

$ /tmp/chromedriver
zsh: exec format error: /tmp/chromedriver

Since I wasn't sure if I was using the .promise() method correctly, I also tried using the equivalent of the README example, but got the same results:

import { createReadStream } from "node:fs";
import { Extract } from "unzipper";

await new Promise((resolve, reject) => {
  createReadStream(driverPkg)
    .pipe(Extract({ path: destinationFolder }))
    .on("close", () => resolve(void 0))
    .on("error", e => reject(e));
});

However, this works just fine with extract-zip@2.0.1:

import extractZip from "extract-zip";

await extractZip("chromedriver_linux64.zip", { dir: "/tmp" })

Then, when I run:

$ md5sum chromedriver
ee3dba5202ae87d7b79c22341030db49

$ /tmp/chromedriver
Starting ChromeDriver 111.0.5563.64 (c710e93d5b63b7095afe8c2c17df34408078439d-refs/branch-heads/5563@{#995}) on port 9515

[Toliak]

Same issue on Windows 11

Is related to #271

[dgdosen]

same issue when run from macos...

[jarlah]

same problem here. in a linux docker image in openshift ...

I ran into this issue. After much research, this appears to be an issue brought on by changes in NodeJS. I was using 18.18.0 when I ran into the issue. Downgrading to v18.15.0 solved the problem. The issue exists in v18.16.0 and above.

[marcogrcr]

Wow @PeterSelvaraj you nailed it, well done and thanks for the hard work! I can confirm this is the case in MacOS 13.5.2.

I'm installing node using asdf and tested chromedriver_mac_arm64.zip:

% unzip chromedriver_mac_arm64.zip 
Archive:  chromedriver_mac_arm64.zip
  inflating: chromedriver            
  inflating: LICENSE.chromedriver

% md5 chromedriver
MD5 (chromedriver) = 5e4ba0b62a072ff281fe9fc769d8665a

Then run:

import { createReadStream, readFileSync } from "node:fs";
import { Extract } from "unzipper";
import { createHash } from "node:crypto";

// version
console.log("Node.js version:", process.versions.node);

// unzipper
await createReadStream("chromedriver_mac_arm64.zip")
      .pipe(Extract({ path: "." }))
      .promise();

// MD5
const buffer = readFileSync("chromedriver");
const md5 = createHash("md5");
md5.write(buffer);
console.log("MD5:", md5.digest().toString("hex"));

Then playing with the .tool-versions => nodejs X.X.X

node@19 worked for some time and then stopped working, node@20 has never worked:

Version range	Tested versions	MD5	OK?
18.13.0-18.15.0	18.13.0, 18.14.0, 18.14.1, 18.14.2, 18.15.0	5e4ba0b62a072ff281fe9fc769d8665a	Yes

I came upon this issue after having done quite a bit of investigation myself on some problems we were having in our app. I found that this is the exact commit in NodeJS that broke it: https://github.com/nodejs/node/commit/654b7474e38e9a6272b73586023848109cfe358c

I essentially built NodeJS from source and did a checkout of commits to see when stuff breaks and when it doesn't

Hit the same issue upgrading to Node v20. Replaced unzipper with yauzl. Works like charm.

import fs from 'fs';
import yauzl from 'yauzl';
import path from 'path';

export async function unzipFile(archiveName: string, destFolder: string): Promise<void> {
  return new Promise((resolve, reject) => {
    try {
      yauzl.open(archiveName, { lazyEntries: true }, function (err, zipfile) {
        if (err) reject(err);
        zipfile.readEntry();
        zipfile.on('entry', function (entry) {
          if (/\/$/.test(entry.fileName)) {
            // Directory file names end with '/'.
            // Note that entries for directories themselves are optional.
            // An entry's fileName implicitly requires its parent directories to exist.
            zipfile.readEntry();
          } else {
            // file entry
            zipfile.openReadStream(entry, function (err, readStream) {
              if (err) reject(err);
              readStream.on('end', function () {
                zipfile.readEntry();
              });
              const writeFileStream = fs.createWriteStream(path.join(destFolder, entry.fileName));
              readStream.pipe(writeFileStream);
            });
          }
        });
        zipfile.on('end', function () {
          resolve();
        });
      });
    } catch (err) {
      reject(new Error(`Error unzipping ${archiveName}: ${err.message}`));
    }
  });
}

Does anyone know if there is any fix on the way? Downgrading to node 18.15. is not an option because the latest supported electron version comes with 18.16. so basically node-unzipper cannot be used with any supported electron app at the moment.

[dy-dx]

This does look like a bug in nodejs, which can cause the fstream dependency to write out of order.

Thanks @Fadorico for finding the change. I've created a nodejs issue with a smaller test case: https://github.com/nodejs/node/issues/51993

Unfortunately the fstream lib is abandoned, so the workaround for unzipper will have to be to switch off of fstream...

[sajeel45]

I was facing the same issue of corrupted files when the zip is extracted! So I found some other package which is working fine for me The package is extract-zip You can install it by using: npm install extract-zip Here is code snippet how you can use it: const extract = require('extract-zip');

try { // Create the folder if it doesn't exist await mkdir(uploadDir, { recursive: true });

const filePath = path.join(uploadDir, file.name);
// Convert ArrayBuffer to Buffer
const buffer = Buffer.from(await file.arrayBuffer());
await writeFile(filePath, buffer);

// Extract the zip file
await extract(filePath, { dir: uploadDir });

return NextResponse.json({
  message: "File uploaded and extracted successfully",
  success: true,
});

} catch (error) { console.error("Error uploading file:", error); return NextResponse.json({ message: "Failed to upload file", success: false, }); }

You can read my comment I have mentioned some other package which is working fine with latest node version

[dy-dx]

The issue has been fixed in the following node.js versions:

• v18.20.0
• v20.12.0
• v21.7.1

But for anyone unable to upgrade, you'll need to switch to a different unzipper library until this gets addressed: https://github.com/ZJONSSON/node-unzipper/issues/261

[ZJONSSON]

Thanks to @dy-dx for following up on the node issue. Although not directly related to this bug (since it's createWriteStream related) we have moved from unmaintained fstream to fs-extra

published as unzipper@0.12.1
