Dear Bug Team!
After logging out of CDE with XEmacs 21.4.5 still running, the XEmacs
process keeps running, and consumes ~49% of CPU.
Upon the next login, the process must be manually killed. This does not
happen for any other CDE proceses (such as terminal windows). It also
doesn't happen with XEmacs 20.4 that came with Solaris. I can reproduce it
in XEmacs 21.4.5, 21.4.8 and 21.5.8, on both hp and sun. This problem ocurrs
when I access unix through exceed 6.2.0.14 under NT4.00.1381. It does not
happen when physically logged into the unix box. By redirecting stderr to a
file, I get the following error message:
xemacs: Fatal I/O Error 131 (Connection reset by peer) on display connection
"dtwh192b.eai.com:0.0"
after 1646 requests (1646 known processed) with 0 events remaining.
I fixed this problem with a mod to function x_IO_handler in file device-x.c.
This is an adaptation of a fix suggested by Chris van Engelen in
comp.emacs.xemacs. See attached file "cve_post.txt".
In the suggested fix, the code traps the broken pipe error (EPIPE, 32 on
sun). In my fix, I added the connection reset error (ECONNRESET, 131 on
sun). See attached file xio_handler_21.4.5_modified.c.
I found similar logic in v20.4 of device-x.c, but not in v21.5.4. So,
perhaps there is a more appropriate place or technique in the v21 codes to
handle the connection reset error.
Thanks,
Ray.
