From: Naftaly RALAMBOARIVONY <[email protected]> Extend the selftest to run against both modes to ensure correct behavior and prevent regressions when operating in a detached HEAD environment.
Two test modes are run: Git attached and detached, via the 'run_tests()' function. Signed-off-by: Naftaly RALAMBOARIVONY <[email protected]> --- changes in v3: - Simplified printouts message in test_head_detached when test failed - Fixed the result message for test_head_detached - Incrementing xpass so it is properly included in the test results --- meta/lib/patchtest/selftest/selftest | 68 +++++++++++++++++++++++++++- 1 file changed, 67 insertions(+), 1 deletion(-) diff --git a/meta/lib/patchtest/selftest/selftest b/meta/lib/patchtest/selftest/selftest index 92acc4d556..74b50f65e9 100755 --- a/meta/lib/patchtest/selftest/selftest +++ b/meta/lib/patchtest/selftest/selftest @@ -84,6 +84,47 @@ def analyze_result(results, patch, counts): return counts +def run_sh(cmd): + """Run a shell command and return its stdout as a stripped string.""" + return subprocess.check_output(cmd, stderr=subprocess.STDOUT, universal_newlines=True, shell=True).strip() + +def get_git_state(): + """Return the current Git HEAD state (branch, commit).""" + try: + inside_repo = run_sh("git rev-parse --is-inside-work-tree") + except subprocess.CalledProcessError: + print("Not a Git repository") + return None + + state = { + "branch": run_sh("git rev-parse --abbrev-ref HEAD"), + "commit": run_sh("git rev-parse HEAD"), + } + + return state + +def restore_git_state(git_state): + assert git_state['branch'] is not None, "Failed to restore git state, no valid branch" + if git_state['branch'] == "HEAD": + run_sh(f"git switch --detach {git_state['commit']}") + else: + run_sh(f"git switch {git_state['branch']}") + +def is_git_state_same(before, after): + ret = True + + for k in ("branch", "commit"): + if before[k] != after[k]: + print(f"Git state changed: {k} changed: {before[k]} -> {after[k]}") + ret = False + + return ret + +def git_detach_head(): + run_sh("git switch --detach HEAD") + assert run_sh("git rev-parse --abbrev-ref HEAD") == "HEAD", "Failed to enter detached HEAD state" + + return get_git_state() # Once the tests are in oe-core, we can remove the testdir param and use os.path.dirname to get relative paths def test(root, patch): @@ -101,6 +142,31 @@ def test_head_attached(patches, counts): counts = analyze_result(results, patch_info, counts) return counts +def test_head_detached(patches, counts): + git_state = get_git_state() + git_st_detach_before = git_detach_head() + patch_info = patches[0] + testid = patch_info["testid"] + results = test(patch_info["root"], patch_info["patch"]) + git_st_detach_after = get_git_state() + counts = analyze_result(results, patch_info, counts) + if not is_git_state_same(git_st_detach_before, git_st_detach_after): + print(" Test '%s' failed with git in detach HEAD mode: state changed after test" % testid.strip(".")) + counts["error"] = counts["error"] + 1 + else: + counts["xpass"] = counts["xpass"] + 1 + print("XPASS: %s.test_head_detached" % os.path.basename(__file__)) + + return counts + +def run_tests(patches, counts): + git_state = get_git_state() + counts = test_head_attached(patches, counts) + counts = test_head_detached(patches, counts) + restore_git_state(git_state) + + return counts + if __name__ == '__main__': counts = { "pass": 0, @@ -118,5 +184,5 @@ if __name__ == '__main__': if not patches: print(f"Error: Unable to find patch(es) in {patchesdir}") sys.exit(1) - counts = test_head_attached(patches, counts) + counts = run_tests(patches, counts) print_results(counts)
