Martin Panter added the comment: GCC’s -Wformat options are documented at <https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wformat-321>. We already enable -Wall by default, which implicitly enables -Wformat, but not -Wformat=2. Apparently, -Wformat=2 enables -Wformat-security, so you shouldn’t have to manually enable it.
The -Wformat-security option enables warnings for stuff like printf(variable), without any extra arguments. Such a call could easily be changed, even if it is not a genuine problem. So I wouldn’t have a problem enabling this warning by default. (See also Issue 23545 proposing a few other warnings.) However I am not convinced it is worth working around the -Wformat-nonliteral warnings, given that all the warnings given above were false positives, and the general workaround would need six or seven preprocessor lines. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20948> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
