resultmodel: guard model in threaded resource cleanup (!58) · Merge requests · Plasma / Plasma Activities Statistics Library

Harald Sitter requested to merge work/sitter/nocrashy into master Feb 09, 2024

this previously was subject to a race condition between ResultModel destruction and the file access finishing. When the file access took long enough the Model would have been deleted leading to a crash.

Instead weakly point to the model via the QObject such that we can then check if still exists by the time we want to call into it
