Having trouble unzipping mac app (atom shell)

[reggi]

I'm attempting to unzip the darwin mac app for atom shell .

I've tried a ton of npm modules as well as issued some bugs but no response.

• adm-zip Unable to unzip mac app cthackers/adm-zip#118
• node-unzip Unable to unzip mac app EvanOxfeld/node-unzip#68
• decompress-unzip
• buckle
• yauzl

Every time I try to unzip the atom shell app with node / programmatically I get this error.

I opened up mac Console and can see it logs the following when I try to run:

1/21/15 4:02:11.440 PM com.apple.xpc.launchd[1]: (com.github.atom-shell.255064[19701]) Could not find and/or execute program specified by service: 13: Permission denied: /Users/thomas/Desktop/wallpaper/wallpaper-app/build/Atom.app/Contents/MacOS/Atom

I was really happy to see that this library had support for symlinks, and it seems to look as it they are working working. However the app still won't open. Thoughts?

The problem is that none of these unzip libs preserve the executive permissions.

Similar issue with workaround: sindresorhus/gulp-zip#38

[reggi]

I created a diff repo between output from ls -laR for extracted versions of atom-shell with decompress-zip and archive utility. Could be useful in understand things better.

Same issue led me to this PR: #32
So I believe we are almost having first decompressor which preserves file permissions.

@szwacz Thats amazing! Really excited!

@reggi did you find any module that works?

@brian-mann Sorry I don't remember where I last left off.

@brian-mann I think the root of my particular issue was codesigning.
