This was mentioned in #31121, but I believe this deserves its own separate issue. If the debug target is specified using a relative path and later the current directory is changed, pdb tries to search for the target in the new current directory. This currently causes pdb to be unable to exit, which is what #31121 and #14743 are about, but even if they are fixed we would still be left with pdb exiting instead of restarting the target. This issues is about the latter.

To reproduce (same as #31121):

$ mkdir foo
$ cat > foo/script.py
import os
os.chdir('foo')
$ python3 -m pdb foo/script.py 
> /home/user/foo/script.py(1)<module>()
-> import os
(Pdb) c
The program finished and will be restarted
