* Support remote sources in a source list
This commit modifies the source_list check so that remote sources
(http(s), ftp, etc.) are not fetched more than once. To do so, it
adds the use of ``__context__`` in ``cp.cache_file`` and
``file.source_list`` to prevent multiple fetches of a single file in the
same salt run.
* Update tests
Added __context__ to test cases to reflect usage of __context__, and
also added file.source_list to mocked funcs for archive.extracted unit
test.
* fixed invalid assumption in file module tests that all linux platforms have
groups with the same name as users (joe:joe etc.). But for
example ArchLinux has only joe:users.
* file module tests now loads user's canonical group name from pwd and
grp python module instead.
The remove command in the file module had guard, `os.path.exists`, in
front of all remove actions. That guard failed on broken symlinks, i.e.
it returned `false` even though the broken symlink existed. Since the
remove actions are properly guarded without the `os.path.exists` guard,
this commits removes it. Now the remove command will also remove broken
symlinks.
Defined "integration.run_tests()" function which can be used to execute
a particular integration test case. Existing bolerplate code in modules
and states tests is replaced with following lines:
if __name__ == '__main__':
from integration import run_tests
run_tests(TestCaseName)
Typical usecase could look like this:
python integration/modules/pip.py --no-clean -vv
