* bignum.c, include/ruby/intern.h (rb_big_eql): exported.

2012-12-25T10:14:12+00:00

* thread.c (recursive_check): object_id maybe a Bignum, not Fixnum on
  LLP64.  see also r38493 and r38548.
  reported by Heesob Park at [ruby-core:51083] [Bug #7607], and patched

* include/ruby/intern.h: add the prototype declaration of

2012-12-22T15:06:22+00:00

  rb_num_coerce_bit.

* numeric.c (rb_num_coerce_bit): the new coerce function for bitwise
  binary operation.

* bignum.c (rb_big_and): use coerce to convert the argument, which isn't
  a Fixnum nor a Bignum, to the corresponding Integer object so that
  bitwise operations can support Integer-mimic objects.

* bignum.c (rb_big_or): ditto.

* bignum.c (rb_big_xor): ditto.

* numeric.c (bit_coerce): ditto.

* numeric.c (fix_and): ditto.

* numeric.c (fix_or): ditto.

* numeric.c (fix_xor): ditto.

* test/ruby/test_integer.rb: add tests for the above changes.

* bignum.c (bigdivrem): optimize the way to retry calculation of

2012-11-27T12:46:32+00:00

  bigdivrem so that the calculation is started from the point where
  the last interruption was occurred.

* bignum.c (bigdivrem1): ditto.

* test/ruby/test_bignum.rb: add a test case for rb_bigdivrem in the
  case that an interruption is occurred during bigdivrem1 is running.

* bignum.c (bigdivrem): restart calculation when bigdivrem1 was

2012-11-26T07:00:04+00:00

  interrupted by signal. Otherwise, ruby script may see a garbage
  value.

* bignum.c (big_div_struct): added volatile to 'stop' member.

2012-11-26T06:49:48+00:00

  Otherwise, "if (bds->stop)" check in bigdivrem1 don't read
  memory and ignore interrupt.
* bignum.c (bigdivrem, rb_big_stop): ditto.
