[Libguestfs] [nbdkit PATCH 0/3] Test zero callback of python plugin

I'm planning on tweaking the language callbacks to support fua; first up is the python bindings. I want to move from: def zero(h, count, offset, may_trim): to a nicer: def zero(h, count, offset, may_trim=False, fua=False): where the C code passes keywords for the flags (we can add new flags as needed), perhaps by using introspection to learn whether the plugin has a mandatory may_trim (old-style) or optional keywords (new style). But any such changes FIRST need to make sure I don't cause regressions, so beef up the testsuite to cover the zero call in the first place :) Eric Blake (3): python: Follow pep8 recommendations tests: Add coverage of zero in language bindings python: Test implementation of zero callback plugins/python/example.py | 10 ++++++++-- tests/python-exception.py | 4 ++++ tests/shebang.py | 5 ++++- tests/test-lang-plugins.c | 7 +++++++ tests/test.py | 22 +++++++++++++++++++--- 5 files changed, 42 insertions(+), 6 deletions(-) -- 2.14.3
