DBUS log
DESCRIPTION
Use Firefox to download small file (Firefox is told to use KDE portal).
Race condition causes KDE portal unable to clear the downloading status in
PowerDevil. System never able to auto sleep.
STEPS TO REPRODUCE
1. Use KDE desktop. Set KDE portal as default
2. Use latest Firefox (153-156) to open a picture URL (eg
https://www.w3schools.com/html/workplace.jpg )
3. Use context menu "Save Image As"
4. In the Qt file picker, select a path and click Save
Watch PowerDevil status:
watch qdbus6 --literal org.kde.Solid.PowerManagement
/org/kde/Solid/PowerManagement/PolicyAgent
org.kde.Solid.PowerManagement.PolicyAgent.ListInhibitions
See:
[Argument: a(ss) {[Argument: (ss) "start_firefox.sh", "Download in progress"]}]
"Download in progress" never cleared ( even after finished download)
Manually restarted KDE portal to get debug log:
env QT_LOGGING_RULES="xdp-kde-inhibit.debug=true;xdp-kde-request.debug=true"
xdg-desktop-portal-kde --replace
log:
xdp-kde-inhibit: Inhibit called with parameters:
xdp-kde-inhibit: handle:
"/org/freedesktop/portal/desktop/request/<Firefox_dbus>/t/<requestID>"
xdp-kde-inhibit: app_id: "start_firefox.sh"
xdp-kde-inhibit: window: "firefox"
xdp-kde-inhibit: flags: 4
xdp-kde-inhibit: options: QMap(("reason", QVariant(QString, "Download in
progress")))
xdp-kde-request: "org.freedesktop.impl.portal.Request"
xdp-kde-request: "Close"
xdp-kde-request:
"/org/freedesktop/portal/desktop/request/<Firefox_dbus>/t/<requestID>"
The "Close" event should occur after download finishs so that the "Downloading"
status cleared,
but there're big chances it FAILS to occur.
After monitoring dbus, found race condition in KDE portal. Simplified dbus log
see attachment.
OBSERVED RESULT
Downloading status never clear after finish
EXPECTED RESULT
Status should be able to clear
