Bug ID: 452566
Summary: KDE offers to open mimetype with application twice
when it inherits the association twice
Product: frameworks-kservice
Version: 5.93.0
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: fa...@kde.org
Reporter: adam.m.fontenot+...@gmail.com
CC: kdelibs-b...@kde.org
Target Milestone: ---
SUMMARY
This is related to, but not quite the same as, Bug 425154 (see last comment),
which describes a corner case that still needs to be addressed...
Basically, if a mimetype inherits the same application twice (which can easily
happen in multiple-inheritance cases), KDE will show the application twice in
menus and the system settings module.
STEPS TO REPRODUCE
1. Create a JSON file.
2. Set okular to open the mimetypes "application/x-executable" and
"text/plain". Apply changes.
3. Right click on the JSON file in dolphin, and see what programs are made
available to open the file.
OBSERVED RESULT
Okular appears twice in the results.
EXPECTED RESULT
Okular appears once in the results, at the position it inherits *first* in a
breadth-first search of the inherited mimetypes of application/json.
SOFTWARE/OS VERSIONS
Linux: Arch Linux (kernel 5.17.1)
KDE Plasma Version: 5.24.4 (X11)
KDE Frameworks Version: 5.93.0
Qt Version: 5.15.3
ADDITIONAL INFORMATION
The positions Okular appears at in the results appear to suggest that kservice
is searching the inherited mimetypes in depth-first order instead of
breadth-first. This is incorrect and leads to the corner case issue described
in the comments of Bug 425154.
