Anders Østhus grapz...@gmail.com added the comment: Ok. But that makes the whole method inconsistent. Basically, if it's on the same filesystem, rename the file, and thus not inheriting ACL. If it's on another use copy2, and inherit ACL. That makes no sense, atleast not to me

[issue11202] Win32: shutil.move does not inherit permissions

Anders Østhus grapz...@gmail.com added the comment: On my system (Win Server 2008 R2 64-Bit, Python 2.7.1), when I use copy, copy2 or move(to another filesystem), the file _will_ get the ACL of the DST folder, and remove any ACL in SRC file that the DST folder does not have. Thus, it doesn't

[issue11202] Win32: shutil.move does not inherit permissions

Anders Østhus grapz...@gmail.com added the comment: Thank you for taking the time to explain it to me, but it still seems inconsistent to me. I did a test with the functions copy, copy2, move, os.rename, copyfile, both on the same filesystem and another filesystem, and the result is: Same

[issue9334] argparse does not accept options taking arguments beginning with dash (regression from optparse)

Anders Kaseorg ande...@mit.edu added the comment: (1) It's only deprecated in the documentation Which is why I suggested un-deprecating it in the documentation. (I want to avoid encouraging programmers to switch away from optparse until this bug is fixed.) # proposed behavior parser

Anders Blomdell anders.blomd...@control.lth.se added the comment: The culprit seems to be 'pysqlite_do_all_statements(self, ACTION_RESET, 0)' in pysqlite_connection_commit, which resets all active statements, but subsequent fetch/fetchall seems to trash the sqlite3 state in the statements
