From: Jonathan Wakely <redi@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org, libstdc++-cvs@gcc.gnu.org Subject: [gcc r12-9974] libstdc++: _versioned_namespace is always non-None Date: Mon, 13 Nov 2023 15:45:17 +0000 (GMT) [thread overview] Message-ID: <20231113154517.E04913838A0C@sourceware.org> (raw) https://gcc.gnu.org/g:a530c288c8ea46f3760ca3adb44eaf2d773492d1 commit r12-9974-ga530c288c8ea46f3760ca3adb44eaf2d773492d1 Author: Tom Tromey <tromey@adacore.com> Date: Tue Oct 3 11:14:45 2023 -0600 libstdc++: _versioned_namespace is always non-None Some code in the pretty-printers seems to assume that the _versioned_namespace global might be None (or the empty string). However, doesn't occur, as the variable is never reassigned. libstdc++-v3/ChangeLog: * python/libstdcxx/v6/printers.py: Assume that _versioned_namespace is non-None. * python/libstdcxx/v6/xmethods.py (is_specialization_of): Assume that _versioned_namespace is non-None.
