ZIP file can't be open on OS X

[xyNNN]

When I implement the ZipStreamedResponse and return a ZipStreamer object I can't open the downloaded zip file on OS X, anyone have a solution for this?

I think this might be file permission related. I can unzip archive.zip from the terminal, in which case I get this:

Changing the file permissions fixes it and lets me view the image normally.

chmod 644 unzipped-file.jpg

Not sure what's causing this or how to fix it though sorry.

Strange behaviour, but thanks for your time and investigation :)

Hello guys,
Sorry, i just see this issue, i will try this on osx as soon as possible.

Hi, firstly congratulations for this pretty useful bundle !

I just have a problem when I zip my files.
When I extract the zipped files, each file is locked.

The file doesn't has right access, and I need to chmod it to open it (I'm on Linux Ubuntu).

Do you have a solution to resolve this ?

Best regards,

André

I'm receiving the same issue where the download zip file is not executable when downloaded. can open via command line. ended up having to use a different library and symfony StreamedResponse to have things work as expected.

Which is a shame because other than the permissions issue, this is everything I needed and would have saved the couple hours of searching/refactoring/learning that I had to do for an alternative.

Looked into things to try to help contribute a fix but think I need to understand zip file creation more to "see what the problem is". I'm sharing what I found here in case someone else is willing to figure out a solution as well.

I'm thinking the issue is somewhere in the central directory record (ZipStreamerBaseFile.php line 128ish)
https://users.cs.jmu.edu/buchhofp/forensics/formats/pkzip.html#centraldirectory

if that's the case, then something in that record creation needs to be updated.

The only other thing I could find is maybe a temporary file needs to be created?

that link uses php's ZipArchive though so may not be relevant.

may the odds ever be in your favour

Hello, I'm about to open the file for lack of permission. Any evolution? I'm running version 1.0
