As noted in the libc++ 19 release notes [1], std::char_traits<> is now
only provided for char, char8_t, char16_t, char32_t and wchar_t, and any
instantiation for other types will fail.
This causes databases/mysql84-server to fail to compile with clang 19
and libc++ 19, resulting in errors similar to:
/usr/include/c++/v1/string:820:42: error: implicit instantiation of
undefined template 'std::char_traits<unsigned char>'
820 | static_assert(is_same<_CharT, typename
traits_type::char_type>::value,
| ^
/wrkdirs/usr/ports/databases/mysql84-client/work/mysql-8.4.2/sql/rpl_log_encryption.h:821:14:
note: in instantiation of template class 'std::basic_string<unsigned
char>' requested here
821 | Key_string m_encrypted_password;
| ^
/usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared
here
23 | struct _LIBCPP_TEMPLATE_VIS char_traits;
| ^
`Key_string` is defined as `std::basic_string<unsigned char>`, which is
no longer possible. So redefine it as a `std::vector<unsigned char>`
instead.
This requires only a few small adjustments in other places: replacing
the `length()` method with the equivalent `size()` method, and adjusting
the arguments for the `assign()` method, which for `std::vector` takes a
begin and end iterator, instead of a begin iterator and a size.
Another issue is that clang 19 now implements CWG 96 [2], which requires
a template argument list after a 'template' keyword, resulting in errors
similar to:
/wrkdirs/usr/ports/databases/mysql84-client/work/mysql-8.4.2/libs/mysql/serialization/archive.h:84:43:
error: a template argument list is expected after a name prefixed by the
template keyword [-Wmissing-template-arg-list-after-template-kw]
84 | return Archive_derived_type::template
get_size(std::forward<Type>(arg));
| ^
/wrkdirs/usr/ports/databases/mysql84-client/work/mysql-8.4.2/libs/mysql/serialization/archive.h:91:43:
error: a template argument list is expected after a name prefixed by the
template keyword [-Wmissing-template-arg-list-after-template-kw]
91 | return Archive_derived_type::template
get_size_written();
| ^
This requires a number of adjustments to various template invocations.
