Bug ID: 440990
Summary: Too many file descriptors inherited by the shell
Product: konsole
Version: 21.08.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: konsole-de...@kde.org
Reporter: g...@marcais.net
Target Milestone: ---
SUMMARY
Konsole seems to start the shell with many (sometimes hundreds) file
descriptors still open, instead of just 0, 1 and 2. I presume konsole should
flag all of its file descriptors with O_CLOSEXEC so that they are not inherited
by the shell, but doesn't seem to do so.
To be fair, other terminals (but not Gnome terminal) display the same behavior.
So the problem of not closing these file descriptors may be upstream from
Konsole.
STEPS TO REPRODUCE
1. Open konsole
2. ls -l /dev/$$/fd
OBSERVED RESULT
```
gusqt@gus-laptop ~ 0 > ls -l /proc/$$/fd

```
EXPECTED RESULT
Only file descriptors 0, 1 and 2, pointing to the console, should be present.
For example, something like:
```
gusqt@gus-laptop ~ 2 0 > ls -l /proc/$$/fd
total 0
lrwx------ 1 gusqt gusqt 64 Aug 14 20:12 0 -> /dev/pts/5
lrwx------ 1 gusqt gusqt 64 Aug 14 20:12 1 -> /dev/pts/5
lrwx------ 1 gusqt gusqt 64 Aug 14 20:12 2 -> /dev/pts/5
```
