Madzipper Reads Archive as Empty

[MannikJ]

I have a problem where Madzipper cannot read the files from an archive I create during a test, whereas when using native ZipArchive there is no issue.

I am currently using PHP 8.3 together with Laravel v.10.39 and the latest Madzipper.

Creates an empty directory:

        $zipper = \Madzipper::make($extractSourcePath);
        $zipper->extractTo($extractTargetPath);
        $zipper->close();

Creates directory as expected containing all the files from the archive:

        $zipArchive = new \ZipArchive;
        $zipArchive->open($extractSourcePath);
        $zipArchive->extractTo($extractTargetPath);
        $zipArchive->close();

It doesn't matter if I am just using extractTo or listFiles, it just cannot read the contents. listFiles will return [] accordingly.

The common test code is:

        $response = $this->get(route('batch.zip.download', [
            'task_files' => $inputTaskFiles->implode('id', ',')
        ]));

        $response->assertStatus(200);

        $response->assertDownload();

        $fileName = 'task_batch';
        $sourceFileName = "{$fileName}.zip";

        $this->getTestStorageDisk()->put(
            $sourceFileName,
            $response->streamedContent()
        );

        $extractSourcePath = $this->getTestStorageDisk()->path($sourceFileName);
        $extractTargetPath = $this->getTestStorageDisk()->path($fileName);

The controller code uses the ZipStream package:

  return response()->streamDownload(function () use ($request, $name) {
            $zip = new ZipStream(
                outputName: $name,
                // enable output of HTTP headers
                sendHttpHeaders: true
            );

           // Add files to archive

            $zip->finish();

            return $zip;
        }, $name, [
            'Content-Type' => 'application/zip',
        ]);

I don't think it even matters how the archive is created, we can assume it's there and not empty.

Maybe someone can help to find out why this happens.
