This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. Please describe as succinctly as possible: - What happened. - What you thought should have happened. - Precisely what you were doing at the time. Please also include any C or lisp back-traces that you may have. ================================================================ Dear Bug Team! I found the strange behavior of asynchronous process I/O, which is the problem latent in the pty stuff, I guess. To reproduce it, M-: (setq process-connection-type t) and evaluate the following expression: (loop for i from 0 below 10 do (let ((process (start-process-shell-command "test" (current-buffer) "tr 'a' 'b'"))) ;; Don't insert the exit status of the process. (set-process-sentinel process #'ignore) (process-send-string process "aaaaaaaaaaaaaaa\n") (process-send-eof process))) I just expected that only the replaced string (that is "bbbbbbbbbbbbbbb\n") should be inserted 10 times. However, I saw "aaaaaaaaaaaaaaa\n" mixed in addition to the process output. bbbbbbbbbbbbbbb aaaaaaaaaaaaaaa bbbbbbbbbbbbbbb aaaaaaaaaaaaaaa bbbbbbbbbbbbbbb aaaaaaaaaaaaaaa bbbbbbbbbbbbbbb bbbbbbbbbbbbbbb bbbbbbbbbbbbbbb bbbbbbbbbbbbbbb bbbbbbbbbbbbbbb bbbbbbbbbbbbbbb bbbbbbbbbbbbbbb If I set process-connection-type to nil and re-evaluate the above expression, the stray strings are disappeared this time. ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux aquair 2.4.18-pre9 #1 Wed Feb 13 15:12:54 JST 2002 i686 unknown ./configure '--with-mule' '--with-site-lisp' XEmacs 21.4.6 "Common Lisp" configured for `i686-pc-linux'.
