[New-bugs-announce] [issue28501] [Patch] Make os.umask() optional

[Ed Schouten]

New submission from Ed Schouten:

CloudABI is a POSIX-like strongly sandboxed runtime environment, for which we got Python to work (https://mail.python.org/pipermail/python-dev/2016-July/145708.html). Patches for this are slowly being upstreamed.

As CloudABI uses a capability-based security model as opposed to a discretionary access control system, there is no support for UNIX credentials and permissions. This means that umask() is also absent.

It looks like umask() is only used by Python in its posixmodule. The attached patch adds a new Autoconf check and adds the proper #if logic around its implementation.

Changes to the Autoconf/Automake files are not provided by this patch, as my versions of these tools generate files containing unnecessary changes.
