From: SeongJae Park <sjpark@xxxxxxxxx> 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") Signed-off-by: SeongJae Park <sjpark@xxxxxxxxx> --- tools/testing/kunit/kunit.py | 26 ++++++++++++++------------ tools/testing/kunit/kunit_kernel.py | 4 ++-- 2 files changed, 16 insertions(+), 14 deletions(-) diff --git a/tools/testing/kunit/kunit.py b/tools/testing/kunit/kunit.py index ebf5f5763dee..8bee2a5fee27 100755 --- a/tools/testing/kunit/kunit.py +++ b/tools/testing/kunit/kunit.py @@ -44,10 +44,10 @@ class KunitStatus(Enum): BUILD_FAILURE = auto() TEST_FAILURE = auto() -def create_default_kunitconfig(): - if not os.path.exists(kunit_kernel.kunitconfig_path): - shutil.copyfile('arch/um/configs/kunit_defconfig', - kunit_kernel.kunitconfig_path) +def create_default_kunitconfig(build_dir=''): + kunitconfig = os.path.join(build_dir, kunit_kernel.kunitconfig_path) + if not os.path.exists(kunitconfig): + shutil.copyfile('arch/um/configs/kunit_defconfig', kunitconfig) def get_kernel_root_path(): parts = sys.argv[0] if not __file__ else __file__ @@ -61,7 +61,7 @@ def config_tests(linux: kunit_kernel.LinuxSourceTree, kunit_parser.print_with_timestamp('Configuring KUnit Kernel ...') config_start = time.time() - create_default_kunitconfig() + create_default_kunitconfig(request.build_dir) success = linux.build_reconfig(request.build_dir, request.make_options) config_end = time.time() if not success: @@ -258,15 +258,17 @@ def main(argv, linux=None): if get_kernel_root_path(): os.chdir(get_kernel_root_path()) + kunitconfig_path = os.path.join(cli_args.build_dir, + kunit_kernel.kunitconfig_path) if cli_args.subcommand == 'run': if not os.path.exists(cli_args.build_dir): os.mkdir(cli_args.build_dir) - if not os.path.exists(kunit_kernel.kunitconfig_path): - create_default_kunitconfig() + if not os.path.exists(kunitconfig_path): + create_default_kunitconfig(cli_args.build_dir) if not linux: - linux = kunit_kernel.LinuxSourceTree() + linux = kunit_kernel.LinuxSourceTree(cli_args.build_dir) request = KunitRequest(cli_args.raw_output, cli_args.timeout, @@ -284,10 +286,10 @@ def main(argv, linux=None): os.mkdir(cli_args.build_dir) if not os.path.exists(kunit_kernel.kunitconfig_path): - create_default_kunitconfig() + create_default_kunitconfig(cli_args.build_dir) if not linux: - linux = kunit_kernel.LinuxSourceTree() + linux = kunit_kernel.LinuxSourceTree(cli_args.build_dir) request = KunitConfigRequest(cli_args.build_dir, cli_args.make_options) @@ -299,7 +301,7 @@ def main(argv, linux=None): sys.exit(1) elif cli_args.subcommand == 'build': if not linux: - linux = kunit_kernel.LinuxSourceTree() + linux = kunit_kernel.LinuxSourceTree(cli_args.build_dir) request = KunitBuildRequest(cli_args.jobs, cli_args.build_dir, @@ -313,7 +315,7 @@ def main(argv, linux=None): sys.exit(1) elif cli_args.subcommand == 'exec': if not linux: - linux = kunit_kernel.LinuxSourceTree() + linux = kunit_kernel.LinuxSourceTree(cli_args.build_dir) exec_request = KunitExecRequest(cli_args.timeout, cli_args.build_dir, diff --git a/tools/testing/kunit/kunit_kernel.py b/tools/testing/kunit/kunit_kernel.py index b557b1e93f98..7dd4268665a8 100644 --- a/tools/testing/kunit/kunit_kernel.py +++ b/tools/testing/kunit/kunit_kernel.py @@ -109,9 +109,9 @@ def get_kconfig_path(build_dir): class LinuxSourceTree(object): """Represents a Linux kernel source tree with KUnit tests.""" - def __init__(self): + def __init__(self, build_dir): self._kconfig = kunit_config.Kconfig() - self._kconfig.read_from_file(kunitconfig_path) + self._kconfig.read_from_file(os.path.join(build_dir, kunitconfig_path)) self._ops = LinuxSourceTreeOperations() signal.signal(signal.SIGINT, self.signal_handler) -- 2.17.1
