"invalid code length" error

[schematical]

Hey, I am using your library and tracked this error through all the way through your library to the node ZLib. The actual error was:

        throw er; // Unhandled 'error' event
              ^
Error: invalid code lengths set
    at Zlib._binding.onerror (zlib.js:295:17)

Process finished with exit code 8

It makes it through the first 3 out of 5 files in the zip but then I keep getting this invalid code length on a file with the name "WIDMIR - FUTURE HVAC FUME HOOD AND SILENCER LOCATIONS - 2nd Floor Addendum 4.pdf"

Its a long name but no crazy characters. I am not sure if it is in the body or what. The actual error has no stack trace but looking investigating took me to here:

https://github.com/uber/nodejs/blob/master/deps/zlib/inflate.c#L869

I can see that it is some how getting passed through the following:

https://github.com/EvanOxfeld/node-unzip/blob/master/lib/parse.js#L136

It doesn't look like a lot of other people are experiencing this issue and I'm not great with the c language. Any help would be much appreciated. Thanks!

Hey @EvanOxfeld I just ran into this problem too. It may have something to do with long paths?

This zip https://dl.dropboxusercontent.com/u/52514/ghattachments/cannot-unzip.zip exhibits the problem. unzip -t says it's ok and unzip handles it just fine.

But...

fs.createReadStream(name)
  .pipe(unzip.Parse())
  .on('entry', function(entry) {
    console.log(entry.path);
    entry.autodrain();
  })

And

fs.createReadStream(name)
  .pipe(unzip.Parse())

If I create a zip that doesn't contain the node_modules directory, node-unzip handles it just fine.

Hello,

I was getting the "invalid code lengths set" error and cloning this repo solved my issue on node v0.10.33

thanks @AnkurMali

Hello it seems that unzip2 already has this problem solved as well which means you don't need to maintain a fork of the repo to fix this issue:

Ya it seems unzip2 is working good for the issue. closing the request
