From 7a3408c49975735e614265d7810a5bd91c699c64 Mon Sep 17 00:00:00 2001 From: matz Date: Tue, 5 Oct 2004 01:37:46 +0000 Subject: * io.c (rb_fopen): mode string copy at the lowest level. * io.c (rb_io_flags_mode): requires output buffer no more. no allocation needed. * array.c (rb_ary_index): takes a block to compare items in an array. [ruby-talk:113069] [Ruby2] * array.c (rb_ary_rindex): ditto. * marshal.c (r_byte): retrieve pointer from string value for each time. [ruby-dev:24404] * marshal.c (r_bytes0): ditto. * enum.c (sort_by_i): re-entrance check added. [ruby-dev:24399] * io.c (io_read): should freeze all reading buffer.
