Python traceback.format_tb 在 Cython Extension 编译后不能完全工作
Python traceback.format_tb doesn't work completely after Cython Extension compiled
- Python版本:3.7
- Cython 版本:0.29.15
源代码:example/example.py
import traceback
def run():
try:
assert 1 == 0
except Exception as e:
log_info = f'Erase failed, exception={type(e).__name__},\n{e},\n{"".join(traceback.format_tb(e.__traceback__))}'
print('*********************')
print(log_info)
print('*********************')
setup.py
from setuptools import setup
from setuptools.extension import Extension
from Cython.Build import cythonize
setup(name='example',
version="0.0",
ext_modules=cythonize(
[
Extension("example.*", ["example/**/*.py"]),
],
build_dir="build",
compiler_directives=dict(always_allow_keywords=True,
language_level='3')))
构建命令:python setup.py build
编译前的输出
*********************
Erase failed, exception=AssertionError,
,
File "example/example.py", line 6, in run
assert 1 == 0
*********************
编译后输出
*********************
Erase failed, exception=AssertionError,
,
File "example/example.py", line 6, in example.example.run
*********************
这是预料之中的,因为在 Cython 将您的代码转译为 C 并编译本机模块后,不再有 Python 代码可供参考。
问题 https://github.com/cython/cython/issues/1755 是相关的,但它也已经开放 3 年多了。
