Unexpected EOF when inflating ZIP

[blacha]

The problem

I have a zip file that I can decompress with other decompressors (ubuntu's unzip, yazul, python3) but when using fflate the zip is unable to be decompressed.

Error: unexpected EOF
    at inflt ([worker eval]:233:25)
    at Inflate.c ([worker eval]:289:18)
    at Inflate.push ([worker eval]:294:29)
    at [worker eval]:263:40
    at MessagePort.<anonymous> ([worker eval]:298:86)

How to reproduce

Using a simple script

import { AsyncUnzipInflate, Unzip } from 'fflate';

const bytes = readFileSync('./address.zip'); 
const unzip = new Unzip((file) => {
  console.log(file.name);
  file.ondata = (err, data, final) => {
    if (err) throw err;
    console.log('got', file.name, data.length, final);
  };
  file.start();
});

unzip.register(AsyncUnzipInflate);
unzip.push(bytes);

with my sample zip file: https://public.chard.com/fflate/address.zip

I'll look into this and let you know what the issue is soon. The streaming unzip API has needed a bit of work for a while now...

Still unsure of the issue here @101arrowz?

Sorry, I've been busy for the last few weeks - I probably won't be able to get to this for a while. To be honest I would just advise against using the streaming unzip API until I can get around to fixing it.

Hi @101arrowz,

I'm encountering the same problem with this file: https://github.com/johan-tribus/fflate/blob/master/file.zip Have you had a chance to investigate the issue yet?

Hi 101arrowz

Thank you for this great tool.

I have the same problem, using unzipSync. Strangely, though, I remember seeing it work on the same file several weeks ago. This makes me think it is perhaps a certain race condition that mostly does not work out (or worse: a Windows update :D).

I hope you find and solve the problem easily.

Hi @101arrowz

Thank you for this great tool.

I had the same problem when using decompressSync. Strangely enough. it works with a downloaded zip file. but after i unzip it then compress on mac. I get error: Unexpected EOF. I have compressed files before and used decompressSync and it worked fine.

I hope you find and solve the problem easily.
