Description

In Windows Vista,

C:\SuperSecretProject>python manage.py collectstatic -l
.....
Symlinking is not supported by this platform (Windows)

But I am an administrator. I have the power to create symlink.

Patch needs improvement: set

The current checks in the PR aren't enough, if you are on python 2.x and run collectstatic on Vista with -l it will fail. Basically symlinking on windows is only supported on windows vista (and above) + admin account + python3.

Also can you clarify on the administrator bits, do you effectively log in as administrator or will every symlink call ask you if you want to allow it?

comment:3 by Vajrasky Kok, 11 years ago

In Windows Vista, to be able to create symlink, I need to right click the Command Line menu, then click "Run as Administrator". Without this, when I create symlink through os.symlink, I will get error that I don't have enough privileges.

Oh, yeah, I forgot that prior Python 3.2, os does not provide symlink in Windows. Sorry about that.

In Windows XP, you could have the ability to create symlink, but you must install third-party driver. According to Python core developers, they are against giving this feature to Windows XP in Python stdlib. http://bugs.python.org/issue19792

So here is the updated PR. https://github.com/django/django/pull/2011

Windows XP -> no symlink
Python 2.7 in Windows Vista -> no symlink
Python 3.3 in Windows Vista -> symlink (of course you must have administrator privilege)

It is possible to give symlink support in Python 2.x in Windows. But that requires ctypes and win api.

But I think I would upset a lot of people in Django if I did that.

I'm accepting the idea in general.

However the feature detection code in the current patch looks messy to me (~30 lines) and hard to get right.

I'd find it more pythonic to create the symlink and provide a suitable error message if that fails. Ask for forgiveness rather than permission :)
