Bug ID: 418636
Summary: Search/Replace exceeds physical ram on 5mb file
Product: kate
Version: 19.12.2
Platform: PCLinuxOS
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: search
Assignee: kwrite-bugs-n...@kde.org
Reporter: hpf...@psnarf.org
Target Milestone: ---
SUMMARY
Stop button unresponsive during search/replace on a 80K-line text file.
KInfoCenter showed swap partition in use. Replace reports processing 27 million
found, which should be only 5k. KSysGuard showed 18 threads, watched ram use
increase from 10.1gb to 10.7gb, when I killed it.
STEPS TO REPRODUCE
1. Capture ldd output into text file.
2. Search for " \(0x" regular expression
3.
OBSERVED RESULT
0 of 27,095,586 processed, should be only 5,078. System briefly froze as the
unused swap partition invoked. Physical ram allocation went from 4gb out of
14.7gb to 10gb+,leaving only 200kb unallocated. Kate unresponsive. Had to kill
it as more processes went to swap and kate allocation increased
EXPECTED RESULT
Replace (0x with newline for sed deletion
