[PATCH v2 02/15] qom: Use g_ascii_strcasecmp instead of strcasecmp

Posted by Kostiantyn Kostiuk 6 days, 1 hour ago

This is a change in semantics. g_ascii_strcasecmp() doesn't honour
locale but strcasecmp() does. But this is OK for at least one reason:
 (1) QEMU always runs with the C locale so there's not an actual
     behaviour change here
 (2) we want the comparison on class names to be a plain ASCII
     one, not to do weird things with "I" in Turkish locales,
     so g_ascii_strcasecmp() is better as it's explicit about that
