Description (last modified by Paolo Dente)

The change to django/contrib/staticfiles/management/commands/collectstatic.py in commit 2cd2d188516475ddf256e6267cd82c495fb5c430 causes the command to overwrite all static files in remote storage (eg. S3), instead of only updatable ones.

A quick workaround is to override the command and restore the previous Command.delete_file() in the subclass, but I suppose this should be fixed.

Easy pickings: unset

Could you be more specific about the steps to reproduce the issue (ideally without S3 involved since Django's test suite cannot rely on that)? If you could provide a test case for tests/staticfiles_tests that would be great.

This line Github link
full_path for remote storages such as S3 is always None
The clause was improperly refactored
It should look like

                            not full_path or full_path and not (self.symlink ^ os.path.islink(full_path))):

@Tim: as far as I can tell, any non-local storage should be affected so a possible test would require mocking Storage or the management command so that Command.local() is False; I can try and write one. On the other hand, it looks like @Vitali spotted the problem with the refactoring, so I don't know how to proceed from here.
