Asserts when encountering invalid files #45
Description
Version: 0.11-1
systemd: 256.9-1
kernel: 6.12.4-arch1-1
While writing a script to find all dl-opened libraries on a system, I ran into this assert when encountering .py files:
Traceback (most recent call last): File "/usr/bin/dlopen-notes", line 142, in <module> notes = [read_dlopen_notes(filename) for filename in args.filenames] ^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/bin/dlopen-notes", line 24, in wrap return list(f(*args, **kwargs)) ^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/bin/dlopen-notes", line 29, in read_dlopen_notes elffile = ELFFile(open(filename, 'rb')) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/elftools/elf/elffile.py", line 84, in __init__ self._identify_file() File "/usr/lib/python3.12/site-packages/elftools/elf/elffile.py", line 570, in _identify_file elf_assert(magic == b'\x7fELF', 'Magic number does not match') File "/usr/lib/python3.12/site-packages/elftools/common/utils.py", line 80, in elf_assert _assert_with_exception(cond, msg, ELFError) File "/usr/lib/python3.12/site-packages/elftools/common/utils.py", line 143, in _assert_with_exception raise exception_type(msg) elftools.common.exceptions.ELFError: Magic number does not match Ideally, invalid & non-existent files (& directories) wouldn't cause asserts like this.
