Willy Tarreau 908071171b BUILD: general: always pass unsigned chars to is* functions ... The isalnum(), isalpha(), isdigit() etc functions from ctype.h are supposed to take an int in argument which must either reflect an unsigned char or EOF. In practice on some platforms they're implemented as macros referencing an array, and when passed a char, they either cause a warning "array subscript has type 'char'" when lucky, or cause random segfaults when unlucky. It's quite unconvenient by the way since none of them may return true for negative values. The recent introduction of cygwin to the list of regularly tested build platforms revealed a lot of breakage there due to the same issues again. So this patch addresses the problem all over the code at once. It adds unsigned char casts to every valid use case, and also drops the unneeded double cast to int that was sometimes added on top of it. It may be backported by dropping irrelevant changes if that helps better support uncommon platforms. It's unlikely to fix bugs on platforms which would already not emit any warning though.		2020-02-25 08:16:33 +01:00
