File 0001-Port-scripting-to-Qt-WebEngine.patch of Package libksysguard5
From 9c16eca77f731a12d2c9e1a2bcb668c0a5a22c54 Mon Sep 17 00:00:00 2001 From: Fabian Vogt <fabian@ritter-vogt.de> Date: Sat, 1 Sep 2018 18:41:59 +0200 Subject: [PATCH] Port scripting to Qt WebEngine Summary: Unfortunately it relies on Qt WebKit features quite intensely, so a few godawful hacks were necessary to make it work. Most of those are needed to workaround restrictions of QWebChannel as bridge to the browser page. We gain: + Independence from WebKit + Support for newer JS and HTML features in scripts We lose: - Performance (especially memory use) - Independence from WebEngine - Sanity Test Plan: Tested the detailed memory info pages on a few processes, info is correct and the page seems to work fully.
