There are two unfortunate aspects to this. One is that most test runs end
like this:
{{{
#!python
Traceback (most recent call last):
File "runtests.py", line 374, in <module>
options.failfast, args)
File "runtests.py", line 220, in django_tests
teardown(state)
File "runtests.py", line 188, in teardown
shutil.rmtree(six.text_type(TEMP_DIR))
File "C:\Program Other\Python27\Lib\shutil.py", line 252, in rmtree
onerror(os.remove, fullname, sys.exc_info())
File "C:\Program Other\Python27\Lib\shutil.py", line 250, in rmtree
os.remove(fullname)
WindowsError: [Error 32] The process cannot access the file because it is
being used by another process:
u'c:\\users\\me\\appdata\\local\\temp\\django_ekeere\\tmprx3hfn'
}}}
The other is that the temp directory isn't removed. That's not a severe
problem when it comes to temp files and directories, but it's not
particularly nice either.
As indicated in the stack trace, the error is caused by the calls to
`os.remove()` in `shutil.rmtree()` in `runtests.teardown()`. As indicated
in the `os.remove()` documentation: "On Windows, attempting to remove a
file that is in use causes an exception to be raised." This includes files
opened by the current process.
The root cause of this, then, is that a number of tests open temporary
files but never close them, thus preventing the cleanup process from
working properly.
