It tells you that it is ready to write but if you don't have data to write you cannot tell that it is in fact closed. ruby internally uses poll() which can tell when a write socket is closed (without attempting a write()) but presents the broken select() interface. ---Files-------------------------------- test.rb (975 Bytes) 0001-io-add-additional-argument-to-fd_select-calls.patch (9.27 KB) 0002-select_internal-add-additional-argument-for-poll-err.patch (4.4 KB) 0003-io-make-use-of-poll-POLLERR-flag.patch (2.18 KB) 0004-io-add-select_with_poll-class-method-when-USE_POLL.patch (2.72 KB) 0005-io-document-IO.select_with_poll.patch (2.04 KB) 0006-thread-use-poll-in-rb_fd_select.patch (6.87 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
