Hi,
After some tests (on a new tmux server, started with "tmux -L test ..."), I
could (partially) reproduce the problem.
Partially, because:
in fstat output there are 2 kinds of "bugged" entries: tty and null
tty: 181 descriptors
null: 320 descriptors
And I arrived to keep descriptors opened against /dev/tty , but not against
/dev/null (for the moment, but I monitor what in my use what generate this...).
This occurs with urlview (textproc/urlview), with a custom url_handler.
Basically urlview take a text in stdin (generally an email), and display a menu
(ncurses) of URLs found in the text. The user choose an URL, and urlview start
a command (in my case, a custom script).
First, my configuration:
$ cat ~/.urlview
# command to invoke for selected URL
COMMAND /home/semarie/.local/bin/urlview_handler.sh
Next, the command started by urlview:
$ cat /home/semarie/.local/bin/urlview_handler.sh
#!/bin/sh
# if TMUX enable, update environment
if [ -n "${TMUX}" ] ; then
eval `tmux show-environment | grep -v '^-' | sed 's/=\(.*\)$/=\"\1\"/'`
unset `tmux show-environment | grep '^-' | sed 's/^-//'`
export `tmux show-environment | grep -v '^-' | sed 's/=\(.*\)$//'`
fi
# check DISPLAY
if [ -n "${DISPLAY}" ] ; then
exec chrome "$@"
fi
# if not DISPLAY
exec lynx "$@"
And when I launch the command:
$ echo 'http://www.openbsd.org/' | urlview
3 new descriptors against "tty" are opened and not closed after the command.
There are directly correlate with the 3 "tmux show-environment" in the script.
I don't remind exactly the purpose of updating the environnement in the
script... should be to keep kerberos ticket or display environnement in
text-mode ... but ?
Additionnaly, running the url_hander alone (without urlview) don't trigger the
problem.
I will disabling the part of "updating environment" in my script (and if I
always need it, I will recall when something won't work !)
I will post when I have more info.
Please let me known if more informations are needed.
Thanks.
