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. :-(
