Feature 11339

Introducing IDL will GOOD: improve performance BAD: increase required knowledeg to hack Ruby

Introducing the primitve “C.foo(x, y)” calling C function “foo” with two VALUEs “x and y” seems good primitive only in prelude.rb. Now, it is only for prelude.rb, not for all C-extensions.

akr pointed out that it will introduce incompatibility compare with C implemented function and Ruby with C function because therea are interrupt timing in Ruby. For example,

  class IO
    def IO.open(..., &b)
        fd = C.sysopen(...)
        f = IO.new(fd)
        …

this code can leak `fd’ if some exception is occur before making IO object (IO object will free fd). In this case, we need to make C functions to make IO objects.

Also, additional TracePoint will be introduced.

status of RubyCI and the expectation of its restoration (usa)

• our storage account is expired from about 2-3 week ago.
• we will replace following azure backends to s3.
• https://github.com/akr/chkbuild/blob/master/chkbuild/upload.rb#L75

about the necessity of r51384 (it takes toooooo looooong time to run test-all) (usa)

Resolved.
