Weird permission error

Hello community,

I just wanted to update one of my AUR packages (https://aur.archlinux.org/packages/geomspace/) and stumbled upon a very strange problem. For some reason the permissions in $srcdir are different from the permissions inside the source archive. Here is how it looks in $srcdir:

$ ls -l /home/photon/PKGBUILDS/geomspace/src/GeomSpace/
insgesamt 36
drwxr-xr-x 3 photon users 4096  4. Jan 16:24 bin
drwxr-xr-x 3 photon users 4096 16. Mär 2014  doc
drwxr-xr-x 4 photon users 4096 16. Mär 2014  extern
drwx------ 2 photon users 4096 16. Mär 2014  i18n
drwx------ 2 photon users 4096  4. Jan 16:24 make
drwxr-xr-x 2 photon users 4096 16. Mär 2014  models
drwx------ 6 photon users 4096 16. Mär 2014  res
drwx------ 6 photon users 4096  4. Jan 16:24 src
drwx------ 2 photon users 4096 16. Mär 2014  tools

And here is how it looks like if I manually extract the source archive:

$ ls -l /home/photon/Desktop/GeomSpace/
insgesamt 36
drwxr-xr-x 2 photon users 4096 16. Mär 2014  bin
drwxr-xr-x 3 photon users 4096  6. Jan 19:43 doc
drwxr-xr-x 4 photon users 4096  6. Jan 19:43 extern
drwxr-xr-x 2 photon users 4096  6. Jan 19:43 i18n
drwxr-xr-x 2 photon users 4096  6. Jan 19:43 make
drwxr-xr-x 2 photon users 4096  6. Jan 19:43 models
drwxr-xr-x 6 photon users 4096  6. Jan 19:43 res
drwxr-xr-x 6 photon users 4096  6. Jan 19:43 src
drwxr-xr-x 2 photon users 4096  6. Jan 19:43 tools

I'm pretty sure that this is some dumb error on my side, because I didn't notice such discrepancies before modifying the package (however I didn't look too closely because I was setting permissions inside $pkgdir through "install -m" and therefore didn't care for permissions in $srcdir). However, now I want to copy whole folders using cp rather than copy single files using install and therefore want to rely on correct permissions in $srcdir which for some mysterious reason fails...

Thanks for any hint,
PhotonX.

Re: Weird permission error

I'm not sure I true understand your problem.
anyway, how do you extract the source?

Re: Weird permission error

That's odd...

Well, I do know that permissions for files inside the source tarball you upload must be 644 or 755, so maybe that has something to do with it?

Re: Weird permission error

When you extract the archive manually, are you passing the -p flag to preserve permissions? If you don't, I assume it just uses your umask to determine the permissions of the extracted files.

Re: Weird permission error

Actually, I did the manual extraction with file-roller. Which options do I need to pass to tar in Order to preserve the permissions inside the archive? The -p option?
