[PATCH V5 0/4] check the python code with pyflakes
From: ShaoHe Feng <shaohef@linux.vnet.ibm.com> V4 -> V5 We do not need pyflakes to run or build Kimchi. It is only used for developers to check code style. V3 -> V4 address Rodrigo's comment. add delete the cloned template in rollback. V2 -> V3 address zhengsheng's comment. improve the SKIP_PYFLAKES_ERR list. V1 -> V2 address Crístian'comment: remove the whole statement "info = self._get_vm(name).inf" address ming's comment: break down the patch into small patches by the pyflakes error. Pyflakes analyzes programs and detects various errors. It works by parsing the source file, not importing it, so it is safe to use on modules with side effects. It's also much faster. This is important to improve the code quality. ShaoHe Feng (4): make pyflakes happly, remove the unused import module make pyflakes happly, remove unused availables add template_delete to rollback after create a template run pyflakes when make check Makefile.am | 7 +++++++ configure.ac | 7 +++++++ src/kimchi/control/plugins.py | 2 +- src/kimchi/featuretests.py | 2 -- src/kimchi/mockmodel.py | 5 ++--- src/kimchi/model/storagepools.py | 2 +- src/kimchi/screenshot.py | 1 - src/kimchi/template.py | 1 - tests/test_model.py | 2 ++ tests/test_server.py | 1 - ui/pages/help/gen-index.py | 1 - 11 files changed, 20 insertions(+), 11 deletions(-) -- 1.8.5.3

From: ShaoHe Feng <shaohef@linux.vnet.ibm.com> We know ModelTests will tear down the template datebase. But it is better to delete the template explicitly. In this way, the test case also can test the template_delete. Also this can make pyflakes happy.
