File 0003-kcms-memory-use-KAuth-dmidecode-helper.patch of Package kinfocenter6
From 375abcd571b991aa1ea8436fad6c7a4d30f62fa1 Mon Sep 17 00:00:00 2001 From: Kristen McWilliam <kmcwilliampublic@gmail.com> Date: Mon, 14 Oct 2024 15:45:02 -0400 Subject: [PATCH 3/3] kcms/memory: use KAuth dmidecode helper Refactor to use a KAuth helper to run dmidecode as root, rather than using the CommandOutputContext. This means the KCM no longer requires the user to enter their password to view memory information, and won't show an obtuse error like before if the user cancelled the password dialog. --- kcms/helpers/dmidecode-helper/helper.cpp | 26 ++++++++++ kcms/helpers/dmidecode-helper/helper.h | 5 ++ .../org.kde.kinfocenter.dmidecode.actions | 7 +++ kcms/memory/CMakeLists.txt | 9 +++- kcms/memory/main.cpp | 48 ++++++++++++++++--- kcms/memory/ui/main.qml | 25 ++++++++-- 6 files changed, 108 insertions(+), 12 deletions(-) diff --git a/kcms/helpers/dmidecode-helper/helper.cpp b/kcms/helpers/dmidecode-helper/helper.cpp index e9d068dc..11921934 100644 --- a/kcms/helpers/dmidecode-helper/helper.cpp +++ b/kcms/helpers/dmidecode-helper/helper.cpp @@ -26,6 +26,24 @@ DMIDecodeHelper::DMIDecodeHelper(QObject *parent) m_dmidecodePath = QStandardPaths::findExecutable("dmidecode");
