Subject: [PATCH v2 1/2] kunit: tool: Respect '.kunitconfig' in 'build_dir'
From: SeongJae Park <sjpark@...zon.de>
Commit d43c7fb05765 ("kunit: tool: fix improper treatment of file
location") removed 'kunit_kernel.kunitconfig_path' modification for the
'--build_dir' argument. As a result, running kunit with '--build_dir'
failed with below error message:
Traceback (most recent call last):
File "./tools/testing/kunit/kunit.py", line 325, in <module>
main(sys.argv[1:])
File "./tools/testing/kunit/kunit.py", line 245, in main
linux = kunit_kernel.LinuxSourceTree()
File "/home/sjpark/linux/tools/testing/kunit/kunit_kernel.py", line 109, in __init__
self._kconfig.read_from_file(kunitconfig_path)
File "/home/sjpark/linux/tools/testing/kunit/kunit_config.py", line 88, in read_from_file
with open(path, 'r') as f:
FileNotFoundError: [Errno 2] No such file or directory: '.kunitconfig'
The error removed after commit 82206a0c06cc ("kunit: tool: handle when
.kunit exists but .kunitconfig does not"). However, it was not the
intention of the commit. It hides the error by ignoring the
'.kunitconfig' in the '--build_dir'.
This commit makes the tool to respect '.kunitconfig' in '--build_dir'
again, while respecting the constantness of
'kunit_kernel.kunitconfig_path', as modifying the variable makes the
'kunit_tool_test.py' fails
Fixes: d43c7fb05765 ("kunit: tool: fix improper treatment of file location")
