From 852348ab65783601e0844b6647ea033668b45c11 Mon Sep 17 00:00:00 2001 From: "Gregory P. Smith" Date: Mon, 5 Jun 2023 23:36:36 -0700 Subject: [PATCH] Display the sanitizer config in the regrtest header. (#105301) Display the sanitizers present in libregrtest. Having this in the CI output for tests with the relevant environment variable displayed will help make it easier to do what we need to create an equivalent local test run. --- Lib/test/libregrtest/main.py | 20 ++++++++++++++++++++ Lib/test/support/__init__.py | 2 +- 2 files changed, 21 insertions(+), 1 deletion(-) diff --git a/Lib/test/libregrtest/main.py b/Lib/test/libregrtest/main.py index 3c3509d0303371..9001ca33b6166a 100644 --- a/Lib/test/libregrtest/main.py +++ b/Lib/test/libregrtest/main.py @@ -526,6 +526,26 @@ def display_header(self): print("== CPU count:", cpu_count) print("== encodings: locale=%s, FS=%s" % (locale.getencoding(), sys.getfilesystemencoding())) + asan = support.check_sanitizer(address=True) + msan = support.check_sanitizer(memory=True) + ubsan = support.check_sanitizer(ub=True) + # This makes it easier to remember what to set in your local + # environment when trying to reproduce a sanitizer failure. + if asan or msan or ubsan: + names = [n for n in (asan and "address", + msan and "memory", + ubsan and "undefined behavior") + if n] + print(f"== sanitizers: {', '.join(names)}") + a_opts = os.environ.get("ASAN_OPTIONS") + if asan and a_opts is not None: + print(f"== ASAN_OPTIONS={a_opts}") + m_opts = os.environ.get("ASAN_OPTIONS") + if msan and m_opts is not None: + print(f"== MSAN_OPTIONS={m_opts}") + ub_opts = os.environ.get("UBSAN_OPTIONS") + if ubsan and ub_opts is not None: + print(f"== UBSAN_OPTIONS={ub_opts}") def no_tests_run(self): return not any((self.good, self.bad, self.skipped, self.interrupted, diff --git a/Lib/test/support/__init__.py b/Lib/test/support/__init__.py index fee83432388856..0b5ff3a5cf545b 100644 --- a/Lib/test/support/__init__.py +++ b/Lib/test/support/__init__.py @@ -414,7 +414,7 @@ def check_sanitizer(*, address=False, memory=False, ub=False): ) address_sanitizer = ( '-fsanitize=address' in _cflags or - '--with-memory-sanitizer' in _config_args + '--with-address-sanitizer' in _config_args ) ub_sanitizer = ( '-fsanitize=undefined' in _cflags or
