comint-run, can't send interrupt to sub job

comint-run, can't send interrupt to sub job

[Robert Andersson]

hi all!

on one of our machines we can not do comint-interrupt-subjob or
comint-kill-subjob. this is a tad annoying. anyone out there that have
seen this problem and got a remedy for it? would love to hear from you
then :)

yours,

right i forgot to say that i am running emacs 21.1.1 on solaris 9. i
have noticed that comint-run does not send any signals to its sub
jobs... neither comint-kill-subjob or comint-quit-subjob seem to work.

i can do something like

        pkill -INT -U $USER pattern

to the sub job and get it to react. so i really speculate that this is
a comint-run problem.

although on another machine it works just fine, useing the same
version of os and emacs and running program.

there, now you have got some additional information about this problem
that i forgot the first time

yours,

no, this was not correct. the other working machine is running solaris
7 not solaris 9. sorry.

We had a problem with 21.2 running on HP systems.  The fellow who
found it commented out the lines in s/hpux11.h relating to POSIX
to fix it.

I don't know if that helps at all but you never can tell...

I don't speak for Goodyear and they don't speak for me.  We're both happy.

uhm, k thanks i tried what you suggested to uncomment the POSIX things
in sol2.h but without any luck.

i will report this bug to the emacs developers...

if you evaluate (while t nil) in scratch buffer, can you interrupt with C-g?
My guess is you can't, there's a bug in polling in emacs 21.2, but that one is
already fixed in CVS.
