rhe e6e66094f9 stringio.c: fix signed integer overflow 
* ext/stringio/stringio.c (strio_seek): Avoid signed integer overflow.
  It's not harmful in practice here, but is still undefined behavior.

* ext/stringio/stringio.c (strio_extend): Check that the new length does
  not exceed LONG_MAX. This fixes the invalid write on the overflow.

* test/stringio/test_stringio.rb (test_write_integer_overflow): Add a
  test case for the above fix in strio_extend().

StringIO

Pseudo IO class from/to String.

This library is based on MoonWolf version written in Ruby. Thanks a lot.

Differences to IO

  • fileno raises NotImplementedError.
  • encoding conversion is not implemented, and ignored silently.
