[issue5220] os.makedirs' mode argument has bad default value
Sindre Myren smyr...@gmail.com added the comment:
I don't understand what you mean when you say how umask works in
relation to Python. How it works in relation to Python isn't different
from how it works for any other Unix program. Consider, for example,
the unix man page for 'open'.
This is what I mean.
The following gnu commands give (on Archlinux):
$ umask
0022
$ mkdir test1
$ mkdir test2 --mode 0777
$ ls -l
drwxr-xr-x 2 sindrero users 4096 Jun 15 00:59 test
drwxrwxrwx 2 sindrero users 4096 Jun 15 00:59 test2
So we see that new folder created with the --mode parameter to gnu's mkdir does
not get the umask masked out.
The following code in python gives:
import os
os.mkdir('test3')
os.mkdir('test4')
exit()
$ ls -l
drwxr-xr-x 2 sindrero users 4096 Jun 15 01:01 test3
drwxr-xr-x 2 sindrero users 4096 Jun 15 01:01 test4
I (as a programmer) have never seen the specific code for python's mkdir
function, And I have no way to know whether I should presume that mkdir in
python works the same way as the gnu command or not. Unless it is documented
that is.
Cheers :)

*Sorry.. A bit quick there. The line
os.mkdir('test4')
should have been:
os.mkdir('test4', 0777)

Sindre Myren smyr...@gmail.com added the comment: I have to agree with jab. While the way relative paths works are more or less common knowledge, the way umask does and does not work in relation to python isn't. It is however given a short description at http://docs.python.org/library/os.html#os.makedirs: ...The default mode is 0777 (octal). On some systems, mode is ignored. Where it is used, the current umask value is first masked out. And as it is documented (briefly) online that the umask *is* used, perhaps it is not necessary to add it to the doc-string? -- nosy: +smyrman ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5220 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
