05:00 AM Ruby Revision adf30005 (git): Use rb_len_t for the lengths left in long

These hold String and Array lengths or offsets into them, so they would truncate on mswin once rb_len_t widens. A build with rb_len_t set to long long reported them.

05:00 AM Ruby Revision a351359b (git): Pick Array#shuffle and #sample indices beyond unsigned long

rb_random_ulong_limited takes an unsigned long, which stays 32 bits on mswin, so once rb_len_t widens an Array of 2**32 elements or more would never yield its tail. A larger limit goes through rand with an Integer, as rb_random_ulong_lim... hsbt (Hiroshi SHIBATA)

05:00 AM Ruby Revision 70e53da3 (git): Reject a string too long for BSD_vfprintf in rb_sprintf

BSD_vfprintf takes the length of a PRIsVALUE field as a long, which is narrower than a String length on mswin once rb_len_t widens.

05:00 AM Ruby Revision 80067ba1 (git): Use ULEN2NUM for StringIO#size

ULONG2NUM would cut the length to 32 bits on mswin once rb_len_t widens. The fallback keeps older Ruby building.

05:00 AM Ruby Revision 66b3c8f3 (git): Reject a string too long for rb_parser_string_t

rb_parser_string_t holds its length as a long, which is narrower than a String length on mswin once rb_len_t widens, so a line or literal of 2GiB or more would be truncated.

05:00 AM Ruby Revision d4a9221e (git): Check the width of rb_len_t values against SIZEOF_RB_LEN_T

These range checks guard values that are now rb_len_t but still compared SIZEOF_LONG, so they would be compiled out once rb_len_t gets wider than long on LLP64. They compile the same while rb_len_t is long. ibf_dump_write takes the size ... hsbt (Hiroshi SHIBATA)

05:00 AM Ruby Revision c1191af5 (git): Raise IndexError for an out-of-range Struct index past Fixnum

rb_struct_pos hands an out-of-range numeric index back through LEN2NUM, which makes a Bignum past the Fixnum range, and invalid_struct_pos then treated it as a member name and raised NameError.

05:00 AM Ruby Revision c4d16f7a (git): Accept SIZEOF_RB_LEN_T defined by the build

mkmf's check_sizeof('rb_len_t') defines SIZEOF_RB_LEN_T as a number, which redefined the macro with different tokens and warned, failing builds that treat warnings as errors. A static assert checks a given value against the type.
