[GitHub] [buildstream] abderrahim opened a new issue #1459: buildstream stages files from tar files with wrong permissions

abderrahim opened a new issue #1459:
URL: https://github.com/apache/buildstream/issues/1459


   Trying to build qemu ([tarball](https://download.qemu.org/qemu-5.2.0.tar.xz)), I noticed that buildstream stages some files as executable even though they shouldn't be. For instance
   ```python
   >>> import tarfile
   >>> tar = tarfile.open('qemu-5.2.0.tar.xz')
   >>> tar.getmember('qemu-5.2.0/pc-bios/hppa-firmware.img').get_info()
   {'name': 'qemu-5.2.0/pc-bios/hppa-firmware.img', 'mode': 436, 'uid': 1000, 'gid': 1000, 'size': 785696, 'mtime': 1607446784, 'chksum': 7844, 'type': b'0', 'linkname': '', 'uname': 'fluxion', 'gname': 'fluxion', 'devmajor': 0, 'devminor': 0}
   ```
   where 436 is 664 in octal. However in the sandbox
   ```bash
   $ ls -l pc-bios/hppa-firmware.img 
   -rwxr-xr-x 1 abderrahim abderrahim 785696 Nov 11  2011 pc-bios/hppa-firmware.img
   ```
   that is 755.
   
   I see the tar plugin does some [funny stuff with the permissions](https://github.com/apache/buildstream/blob/master/src/buildstream/plugins/sources/tar.py#L67), the error certainly lies in there.
