Here is a summary of the articles posted to ruby-dev.

[ruby-dev:28502] rb_gc_call_finalizer_at_exit()

Nagai, who is a maintainer of tcltklib, asked how to know that
functions are
called by rb_gc_call_finalizer_at_exit() in the C layer in order to
fix a
problem of tcltklib. However, the current ruby doesn’t provide such a
way.

[ruby-dev:28456] Kconv.toxxx with -m0

Naruse requested for comment on the proposal to change the behavior of
the
methods of Kconv such as “tojis”. Currently, those methods perform
mime decoding
in default, since nkf runs with the option ‘-m’(enable mime decoding)
in default.
If this change is accepted, the nkf module of ruby calls nkf with
‘-m0’(disable
mime decoding) and those methods will not perform mime decoding in
default.

[ruby-dev:28509] improving the speed of rational

Funaba proposed that ruby should adopt the rational library[1]
developed by Hara, since
it is faster than the current rational library. This proposal has been
accepted, and it
will be included in ruby-1.9.

[ruby-dev:28589] Float#div and Float#divmod

Hara proposed that -3.4.div(1.1) should return -4 instead of -3 in
ruby-1.8.4 as is in the
case of ruby-1.9. In addition, he proposed that -3.4.divmod(1.1)
should return [-4, 1.0]
instead of [-4.0, 1.0], since it should be the pair of the results of
div and %. This
proposal has been accepted.
