Sorry, something went wrong.
…ks on macOS (pythonGH-99768) On macOS all file descriptors for a particular file in /dev/fd share the same file offset, that is ``open("/dev/fd/9", "r")`` behaves more like ``dup(9)`` than a regular open. This causes problems when a user tries to run "/dev/fd/9" as a script because zipimport changes the file offset to try to read a zipfile directory. Therefore change zipimport to reset the file offset after trying to read the zipfile directory. (cherry picked from commit d08fb25) Co-authored-by: Ronald Oussoren <ronaldoussoren@mac.com>

On macOS all file descriptors for a particular file in /dev/fd
share the same file offset, that is open("/dev/fd/9", "r") behaves
more like dup(9) than a regular open.
This causes problems when a user tries to run "/dev/fd/9" as a script
because zipimport changes the file offset to try to read a zipfile
directory. Therefore change zipimport to reset the file offset after
trying to read the zipfile directory.
