Bug ID: 413565
Summary: Kate can hang the whole system by opening a large file
Product: kate
Version: 19.08.2
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: application
Assignee: kwrite-bugs-n...@kde.org
Reporter: anon...@openmailbox.org
Target Milestone: ---
SUMMARY
By opening a very large file (say 1Gb or more) with Kate, either by mistake or
on purpose, it can hang the whole system forcing the user to reboot or reset.
STEPS TO REPRODUCE
1. Download a large file. I downloaded this and forgot to mark as executable,
opened it with Kate by double click https://benchmark.unigine.com/superposition
(1.5Gb .run file)
2. Click on the right hand side of the Kate window (text preview pane) or wait
a few seconds
3. Apparently, all available ram is filled and the system hangs completely (I
have 8Gb of system ram + swap and it hangs pretty much immediately especially
if I click on the preview pane)
EXPECTED RESULT
Either a warning that I'm opening a file too large, or at the very least the
program not filling up the entire system ram to the point of hanging the whole
system.
