When I build python (version 2.7.13), I find the build results are different every time. It seems to be caused by some times tamps, and they may be generated by the code below: Lib/py_compile.py:106: with open(file, 'U') as f: Lib/py_compile.py:107: try: Lib/py_compile.py:108: timestamp = long(os.fstat(f.fileno()).st_mtime) Lib/py_compile.py:109: except AttributeError: Lib/py_compile.py:110: timestamp = long(os.stat(file).st_mtime) Lib/py_compile.py:111: codestring = f.read() As we know, reproducible build is a good way to counter malicious attacks that generate malicious executables, by making it easy to recreate the executable to determine if the result is correct. How can I eliminate the differences caused by the time stamps? Just remove some code? Or is there any configuration? If we can't eliminate the difference now, can lsof support it in future versions? Thank you. |
