Description
Feature or enhancement
Proposal:
I was working on a tool on Linux where I'm updating yaml files on disk. I need to replace the file when the data changes. I was looking into using a tempfile created with O_TMPFILE, writing the content, and then replacing the original file using linkat. This would provide a simple atomic replacement of the file without needing to do a lot of file handshaking, etc.
However, at the moment tempfile.TemporaryFile passes the O_EXCL flag to io.open, this prevents the file descriptor from being used in a linkat call.
The TemporaryFile code already removes the O_CREAT flags from the standard open flags when using O_TMPFILE.
Would it be okay to remove O_EXCL from the open flags as well?
Has this already been discussed elsewhere?
This is a minor feature, which does not need previous discussion elsewhere
