Ronald Oussoren added the comment: I'd be +1 on extending the zipfile API in 3.4 (with a documentation update in older releases as suggested by anatoly): * Add a method or property to ZipInfo for (un)packing the external_attr field * Add an keyword argument to Zipfile.extract and Zipfile.extractall that toggles restoring file permissions. This should be off by default for backward compatibility. The code that restores the file permissions should be careful to avoid security problems, IMHO it should by default ignore the SUID en SGID bits. ---------- components: +Library (Lib) nosy: +ronaldoussoren stage: -> needs patch type: -> enhancement versions: -Python 3.5 _______________________________________ Python tracker http://bugs.python.org/issue18262 _______________________________________

Alex Lord added the comment: Here's a documentation patch for 2.7 that informs the users that Zipfile.extra and Zipfile.extraall don't save permissions and that Zipfile.writestr will use ZipInfo.extra_attr or default to chmod permission set of 0600. ---------- keywords: +patch nosy: +Alex.Lord versions: -Python 2.6, Python 3.1, Python 3.2, Python 3.3, Python 3.4 Added file: http://bugs.python.org/file34858/Issue18262_27.patch _______________________________________ Python tracker http://bugs.python.org/issue18262 _______________________________________
