tomoya ishida fd1bafc11f [ruby/stringio] Fix ascii_only? flag in strio_write ... (https://github.com/ruby/stringio/pull/77) Followup of #79 `rb_str_resize()` was changed by b0b9f7201a . ```c rb_str_resize(string, shorter) // clear ENC_CODERANGE in some case rb_str_resize(string, longer) // does not clear ENC_CODERANGE anymore ``` ```c // rb_str_resize in string.c if (slen > len && ENC_CODERANGE(str) != ENC_CODERANGE_7BIT) { ENC_CODERANGE_CLEAR(str); } ``` I think this change is based on an assumption that appending null bytes will not change flag `ascii_only?`. `strio_extend()` will make the string longer if needed, and update the flags correctly for appending null bytes. Before `memmove()`, we need to `rb_str_modify()` because updated flags are not updated for `memmove()`. https://github.com/ruby/stringio/commit/b31a538576		2024-01-18 03:42:21 +00:00
