Error: invalid signature: 0x7d70fadf

See original GitHub issue

I’ve got a script that downloads zips from github and unzips them into a temporary directory.

On machines with 4 gigs or less, it’s crashing on any file over 2 megs. - that is a sample that I’m getting the zip from.

Below is the message I am seeing. The signature changes each time, but it happens on mac, linux, and windows. On my macbook pro with 8 gigs of ram, it works fine (I’ve pulled down 20 meg files).

Error: invalid signature: 0x7d70fadf
    at C:\my_project\node_modules\unzip\lib\parse.js:1:1127
    at process._tickCallback (node.js:351:13)

Getting such error some times on extracting file via ftp. Solution was to subscribe stream to ‘error’ event. Simplified to fs, like

function unzipFile(file, callback) {
        .once('error', function () {
            unzipFile(file, callback)
        .on('entry', function (entry) {
            var data = ''
            entry.on('data', function (chunk) {
                data += chunk
            entry.on('end', function () {
                callback(null, data)

Should work, if you get this error not permanent, but from time to time
