Dear Bug Team! In the last day or so I've observed loss of process output (from "C-u M-! cd /path/to/xemacs/21.5; cvs diff ...") and (I think) a truncated message from Gnus. I've been able to observe the process problem again and it occurred in the same place in the cvs diff, but I don't have a reproducible test case yet. I have been unable to reproduce it at all in a shell buffer or in output to a temp *Shell Command Output* buffer, only when inserting into an existing buffer. There was content in the buffer already (I haven't tried to reproduce in an empty buffer yet). I've tried using for i in `seq 1 1000`; do echo 'The quick brown fox jumps over the lazy dog.'; done in several contexts, but couldn't get it to reproduce. I've also tried cat'ing a file containing 10000 copies of that line, but didn't observe any lossage. I tried both tests in an empty buffer, and then into the "middle" of the output of the previous test. No lossage. It occurred to me that maybe a process that did some waiting would exhibit lossage, I tried for j in `seq 1 50`; do for i in `seq 1 20`; do echo "$i The quick brown fox jumps over the lazy dog."; done; sleep 1; done but got no sorrow. Unfortunately I can't get it to reproduce with CVS right now, either, but I did see it twice earlier. The cvs diff is different, so it seems to be very sensitive to the exact data involved.:-( The truncated message could be pilot error, but with the other lossage confirmed, I'm reporting it. This is for 21.5.16 + recent patches, but I don't think anything in the process area has changed for a while, so any reasonably recent 21.5 is probably suspect. :-( ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux tleepslib 2.4.20 #6 Tue Apr 1 18:33:57 JST 2003 i686 GNU/Linux /coda/tleepslib.sk.tsukuba.ac.jp/Software/XEmacs/21.5/configure '--with-widgets=athena' '--with-athena=3d' '--with-dialogs=athena' '--with-mule' '--with-xim=xlib' '--with-xfs' '--external-widget' '--with-modules' '--debug' '--error-checking=all' '--memory-usage-stats' XEmacs 21.5-b16 "celeriac" (+CVS-20031105) configured for `i686-pc-linux'.
