Bug report
I have encountered a possible regression while I was testing pyrsistent with python3.12_beta1, seetobgu/pyrsistent#275. Tests fail with following error:
/usr/lib/python3.12/site-packages/_pytest/python.py:617: in _importtestmodule mod = import_path(self.path, mode=importmode, root=self.config.rootpath)/usr/lib/python3.12/site-packages/_pytest/pathlib.py:564: in import_path importlib.import_module(module_name)/usr/lib/python3.12/importlib/__init__.py:90: in import_module return _bootstrap._gcd_import(name[level:], package, level)<frozen importlib._bootstrap>:1293: in _gcd_import ???<frozen importlib._bootstrap>:1266: in _find_and_load ???<frozen importlib._bootstrap>:1237: in _find_and_load_unlocked ???<frozen importlib._bootstrap>:841: in _load_unlocked ???/usr/lib/python3.12/site-packages/_pytest/assertion/rewrite.py:178: in exec_module exec(co, module.__dict__)tests/hypothesis_vector_test.py:48: in <module> PVectorAndLists = st.lists(st.builds(RefCountTracker)).map(/usr/lib/python3.12/site-packages/hypothesis/strategies/_internal/strategies.py:347: in map if is_identity_function(pack):/usr/lib/python3.12/site-packages/hypothesis/internal/reflection.py:638: in is_identity_function return bool(re.fullmatch(r"lambda (\w+): \1", get_pretty_function_description(f)))/usr/lib/python3.12/site-packages/hypothesis/internal/reflection.py:432: in get_pretty_function_description return extract_lambda_source(f)/usr/lib/python3.12/site-packages/hypothesis/internal/reflection.py:312: in extract_lambda_source source = inspect.getsource(f)/usr/lib/python3.12/inspect.py:1274: in getsource lines, lnum = getsourcelines(object)/usr/lib/python3.12/inspect.py:1266: in getsourcelines return getblock(lines[lnum:]), lnum + 1/usr/lib/python3.12/inspect.py:1241: in getblock for _token in tokens:/usr/lib/python3.12/tokenize.py:451: in _tokenize for token in _generate_tokens_from_c_tokenizer(source, extra_tokens=True):/usr/lib/python3.12/tokenize.py:542: in _generate_tokens_from_c_tokenizer for info in c_tokenizer.TokenizerIter(source, extra_tokens=extra_tokens):E File "<string>", line 1E lambda l: (l, pvector(l)))E ^E SyntaxError: unmatched ')'
It is triggered for this code (seehttps://github.com/tobgu/pyrsistent/blob/cc90f3e2b339653fde0df422aaf3ccdb3fc1225d/tests/hypothesis_vector_test.py#L48-L49 )
PVectorAndLists=st.lists(st.builds(RefCountTracker)).map(lambdal: (l,pvector(l)))
if I concatenate it to one line, everything works. I also tried to backport fix for#104866 as it sounds relevant, but it didn't solved the issue.
