This gives a minor speedup ratio of 2-3% in the new bm_io_nonblock_noex benchmark as well as reducing code. * benchmark/bm_io_nonblock_noex.rb: new benchmark * ext/openssl/ossl_ssl.c (no_exception_p): new function (ossl_start_ssl): adjust for no_exception_p (ossl_ssl_connect): adjust ossl_start_ssl call (ossl_ssl_connect_nonblock): ditto (ossl_ssl_accept): ditto (ossl_ssl_accept_nonblock): ditto (ossl_ssl_read_internal): adjust for no_exception_p (ossl_ssl_write_internal): ditto (ossl_ssl_write): adjust ossl_write_internal call (ossl_ssl_write_nonblock): ditto * ext/stringio/stringio.c (strio_read_nonblock): delay exception check * io.c (no_exception_p): new function (io_getpartial): call no_exception_p (io_readpartial): adjust for io_getpartial (get_kwargs_exception): remove (io_read_nonblock): adjust for io_getpartial, check no_exception_p on EOF (io_write_nonblock): call no_exception_p (rb_io_write_nonblock): do not check `exception: false' (argf_getpartial): adjust for io_getpartial [ruby-core:69778] [Feature #11318] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51113 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
