He was thinking if we could instead drop the minimal version back to 3.6. I think we can do so, see below. Perhaps we should drop the import and then chain this patch on top of that, specifying a minimum version of 3.6? Checking out https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/?h=kunit-fixes The offending "annotations" import is related to type annotations. Specifically https://www.python.org/dev/peps/pep-0563/ So let's see how the two most popular typecheckers fare. pytype is happy with or without import. mypy has the same issues with or without the import. $ mypy tools/testing/kunit/*.py tools/testing/kunit/kunit_kernel.py:227: error: Item "_Loader" of "Optional[_Loader]" has no attribute "exec_module" tools/testing/kunit/kunit_kernel.py:227: error: Item "None" of "Optional[_Loader]" has no attribute "exec_module" tools/testing/kunit/kunit_kernel.py:228: error: Module has no attribute "QEMU_ARCH" tools/testing/kunit/kunit_kernel.py:229: error: Module has no attribute "QEMU_ARCH" So clearly it's not doing anything for them. Taking a look over 87c9c1631788 ("kunit: tool: add support for QEMU") next then... I don't see anything that would warrant the import, so we should probably drop it. In that case, the minimum supported version should drop back down to 3.6. We use enum.auto, which is from 3.6 https://docs.python.org/3/library/enum.html#enum.auto We could consider stopping using that, and I think we might be then 3.5-compatible. Maybe we have a chain of 3 patches then, drop the import, drop auto, and then add in a >=3.5 version check? > ^ > SyntaxError: future feature annotations is not defined > > This commit adds a version assertion in 'kunit.py', so that people get > more explicit error message like below: > > Traceback (most recent call last): > File "./tools/testing/kunit/kunit.py", line 15, in <module> > assert sys.version_info >= (3, 7), "Python version is too old" > AssertionError: Python version is too old > > Signed-off-by: SeongJae Park <sjpark@amazon.de> > Acked-by: Daniel Latypov <dlatypov@google.com> > --- > > Changes from v1 > - Add assertion failure message (Daniel Latypov) > - Add Acked-by: Daniel Latypov <dlatypov@google.com> > > tools/testing/kunit/kunit.py | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/tools/testing/kunit/kunit.py b/tools/testing/kunit/kunit.py > index be8d8d4a4e08..6276ce0c0196 100755 > --- a/tools/testing/kunit/kunit.py > +++ b/tools/testing/kunit/kunit.py > @@ -12,6 +12,8 @@ import sys > import os > import time > > +assert sys.version_info >= (3, 7), "Python version is too old" > + > from collections import namedtuple > from enum import Enum, auto > > -- > 2.17.1 > ^ permalink raw reply [flat|nested] 12+ messages in thread

Actually, now I've gotten python3.6 installed on my machine, I see we have another issue. We pass text=true to subprocess. That didn't exist back in 3.6, see https://docs.python.org/3.6/library/subprocess.html We can workaround that, but there's more chance of subtle bugs that I'd rather we don't touch it. > > Checking out https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/?h=kunit-fixes > > The offending "annotations" import is related to type annotations. > Specifically https://www.python.org/dev/peps/pep-0563/ > > So let's see how the two most popular typecheckers fare. > > pytype is happy with or without import. > mypy has the same issues with or without the import. > > $ mypy tools/testing/kunit/*.py > tools/testing/kunit/kunit_kernel.py:227: error: Item "_Loader" of > "Optional[_Loader]" has no attribute "exec_module" > tools/testing/kunit/kunit_kernel.py:227: error: Item "None" of > "Optional[_Loader]" has no attribute "exec_module" > tools/testing/kunit/kunit_kernel.py:228: error: Module has no > attribute "QEMU_ARCH" > tools/testing/kunit/kunit_kernel.py:229: error: Module has no > attribute "QEMU_ARCH" > > So clearly it's not doing anything for them. > > Taking a look over 87c9c1631788 ("kunit: tool: add support for QEMU") > next then... > I don't see anything that would warrant the import, so we should > probably drop it.
