Subject: [PATCH] Improve the heuristic for detecting old-style AppStream
|
|
|
698863 |
override files
|
|
|
698863 |
|
|
|
698863 |
The heuristic was trying to detect old-style AppStream override files
|
|
|
698863 |
that have the following structure:
|
|
|
698863 |
|
|
|
698863 |
<component type=desktop>
|
|
|
698863 |
<id>org.kde.amarok.desktop</id>
|
|
|

<category>Featured</category>

</categories>
|
|
|
698863 |
</component>
|
|
|
698863 |
|
|
|
698863 |
When it found one, it gave it the wildcard quirk to avoid leaking the
|
|
|
698863 |
result to the installed apps list.
|
|
|
698863 |
|
|
|
698863 |
This however incorrectly tripped on old appdata files that didn't
|
|
|
698863 |
specify name and relied on filling the missing name/summary/icon from
|
|
|
698863 |
the desktop file.
|
|
|
698863 |
|
|
|
698863 |
Fix this by tightening the heuristic and also look for
|
|
|
698863 |
<metadata_license> that none of the override files should have.
|
|
|
698863 |
|
|
|

This fixes RHEL firefox package to correctly show up when clicking on
|
|
|
698863 |
'Show Details' in GNOME Shell.
