Bug ID: 436288
Summary: Wrong indentation in pre-formatted html content (5.78
regression)
Product: frameworks-syndication
Version: 5.80.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kdepim-b...@kde.org
Reporter: alex.mil...@gmx.de
Target Milestone: ---
Since commit 9a54df8b ("Port away from deprecated QXmlInputSource"),
syndication changes the indentation of lines that start with a tag in the html
content of a feed item. That doesn't matter in most places, but it's a problem
where whitespace should be preserved, like in a <pre> block or a tag with
style="white-space:pre".
As a result, after upgrading from frameworks 5.77 to 5.80, newly fetched
articles of a feed that regularly uses pre-formatted content with additional
markup are shown with wrongly indented lines in akregator, while old, archived
articles still render correctly. Reverting the commit mentioned above fixes the
problem.
A small made-up example to illustrate the problem:
If an article contains
<pre>
line 1
<b>line</b> 2
line 3
</pre>
then several spaces will be added in front of line 2, which is wrong.
The offending commit should be reverted and then the deprecated method may be
replaced with a different solution that doesn't cause regressions.
