New submission from WGH <w...@torlan.ru>:
In Linux, it's possible to create an unnamed temporary file in a specified directory by using open with O_TMPFILE flag (as if it was created with random name and immediately unlinked, but atomically). Unless O_EXCL is specified, the file can be then linked into filesystem using linkat syscall. It would be neat if it was possible in Python. There're a couple of things missing: 1) tempfile.TemporaryFile creates a file with O_EXCL flag, which prevents linking it into filesystem. 2) linkat must be called with AT_SYMLINK_FOLLOW flag (otherwise EXDEV is returned), which is broken right now (#37612) ---------- components: Library (Lib) messages: 401676 nosy: WGH priority: normal severity: normal status: open title: Support for linking unnamed temporary files into filesystem on Linux type: enhancement _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45178> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
