* lib/irb.rb: fix up r65674kazu2018-11-121-3/+3
| | | | git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65676 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* ~(unsigned char) is not unsigned charshyouhei2018-11-121-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | The unary ~ operator excercises integer promotion of the operand _before_ actually applying bitwise complement (cf: ISO/IEC 9899:1990 section 6.3.3.3). Which means `~buf[i]` is in fact `(int)~(int)buf[i]`. The problem is, when buf[i] is 0xFF: buf[i] 0xFF (int)buf[i] 0x0000_00FF ~(int)buf[i] 0xFFFF_FF00 This is -256, out of unsigned char range. The proposed fix is to change the char signed. By doing so, buf[i] 0xFF (signed char)buf[i] 0xFF (int)(signed char)buf[i] 0xFFFF_FFFF ~(int)(signed char)buf[i] 0x0000_0000 This is 0, does not overflow. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65675 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* Document binding.irb on Binding [ci skip]k0kubun2018-11-121-1/+57
| | | | | | | | | | | | | | | | For some reason this very useful method was undocumented since it was added in 493e48897421d176a8faf0f0820323d79ecdf94a which makes finding it in the docs impossible before this change. I've added a detailed example with sample code because it's one of the most powerful tools to debug Ruby code and I believe very few people are aware of it due to the lack of documentation.

* numeric.c: avoid division by zeroshyouhei2018-11-091-11/+43
| | | | | | | | | | | | | | | | | | | In C, division by zero is undefined, even if the expression is double (cf: ISO/IEC 9899:1990 section 6.3.5). OTOH we have tests about such operations and results, means we expect no exceptional situation shall occur. We need to carefully reroute the situation, and generate what is needed. See also: https://travis-ci.org/ruby/ruby/jobs/452680646#L2943 PS: Recently (last two decades), C have Annex. F document. It normatively specifies that the division operator is IEEE 754's division operator (cf: ISO/IEC 9899:1999 section F.3). If we could move to such newer version this could be no problem.

* fix passing wrong `passed_bmethod_me`.ko12018-11-093-17/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * vm_core.h: remove `rb_execution_context_t::passed_bmethod_me` and fix functions to pass the `me` directly. `passed_bmethod_me` was used to make bmethod (methods defined by `defined_method`). `rb_vm_invoke_bmethod` invoke `Proc` with `me` information as method frame (`lambda` frame, actually). If the proc call is not bmethod call, `passed_bmethod_me` should be NULL. However, there is a bug which passes wrong `me` for normal block call. http://ci.rvm.jp/results/trunk-asserts@silicon-docker/1449470 This is because wrong `me` was remained in `passed_bmethod_me` (and used incorrectly it after collected by GC). We need to clear `passed_bmethod_me` just after bmethod call, but clearing is not enough. To solve this issue, I removed `passed_bmethod_me` and pass `me` information as a function parameter of `rb_vm_invoke_bmethod`, `invoke_block_from_c_proc` and `invoke_iseq_block_from_c` in vm.c. * vm.c (invoke_iseq_block_from_c): the number of parameters is too long so that I try to specify `ALWAYS_INLINE`. * vm.c (invoke_block_from_c_proc): ditto. * vm_insnhelper.c (vm_yield_with_cfunc): now there are no pathes to use bmethod here. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65636 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
