            Bug ID: 406395
           Summary: konsole history fill tmpfs
           Product: konsole
           Version: 18.12.3
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR

SUMMARY


Recently konsole had a strange behaviour and is filling the tmpfs (/tmp) with a
huge history file. My scrollback was configured to be unlimited as it is for
years. I tried to update my system and I noticed some error message at the
installation of the kernel. I investigated and find that tmpfs was full. I
removed the files in it and everything went back to normal (I finished the
update properly) but the day after I got the same problem when doing normal
operation. This time I looked a little bit more in the culprit and found that
konsole had a nearly 8Gb history file! It never happen before so I am
suspecting a new bug.
I am removing the "unlimited scrollback" for the time beeing and it seems to be
a working workaround.

I filled a bug report on archlinux (https://bugs.archlinux.org/task/62292) but
it was considered as 'not a bug'. I must admit that I am surprised that a
software who fill a file in less a day with nearly 8Gb is considered as a
normal behavior and so not a bug especially when the stability of the system is
in cause and that I never had that behavior before (same configuration for
years) so the bug report here since it is not considered one due to the
packaging.

Thanks for KDE.

STEPS TO REPRODUCE
1. Start console
2. Configure scrollback to be unlimited
3. wait and see the error message appearing because of the full tmpfs

OBSERVED RESULT

Full tmpfs (/tmp )

EXPECTED RESULT

Normal size for history for a single day of usage.
