Bug ID: 358915
Summary: Search large open file for reg ex 'error|' freezes
xorg
Product: kate
Version: unspecified
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: search
Assignee: kwrite-bugs-n...@kde.org
Reporter: malc...@boura.org
Arch Linux Kate version
Version 15.12.1
Using:
KDE Frameworks 5.18.0
Qt 5.5.1 (built against 5.5.1)
The xcb windowing system
KDE Plasma Version 5.5.4
Kernel Version 4.4.4-3-ARCH
64 bit
CPU 4@3.4G
Memory 7.7GiB
Using search plugin, open files, regular expression, case insensitive
Two files open: One small file with excerpts from a large one 134K, 1300 lines.
Entering expression 'error|warning|failed'
Got as far as the first | and the desktop froze.
Xorg CPU at 100%
Had not recovered after a coffee trip, probably 10 minutes or so. Killing Kate
did recover the desktop.
Second run: I started with search in folder plain text. Then switched into open
file, regular expression and it worked.
Third: I then deleted the string back to 'error', typed '|' and it froze again.
My guess is that 'error|' resulted in an attempt to build a found list
containing 1300 or so items which gave the UI more than it could handle in a
sensible time.
