Bug ID: 450411
Summary: Loading files with CRLF lineendings causes high CPU
load
Product: kdiff3
Version: 1.9.4
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: application
Assignee: reeves...@gmail.com
Reporter: sutu...@yahoo.com
Target Milestone: ---
SUMMARY
STEPS TO REPRODUCE
1. Create a large files with CRLF line endings, i.e. using python:
open('test', 'w').writelines('a' * 100 + '\r\n' for _ in range(5000))
2. Comparing the file with any other (or with itself) takes a long time and
uses full CPU
OBSERVED RESULT
Freeze happens when lineendings are not unix lineendings.
EXPECTED RESULT
Line ending shouldn't affect load times

ADDITIONAL INFORMATION

It doesn't get to loading the second file
Also tested with windows (1.9.4 and latest nightly from binary factory)
