patchreview: allow updating branch diffs

Authored by rjvbb on Aug 19 2017, 6:18 PM.



This is a small patch introducing a feature that's part of my personal patchreview diff contextlines mod, but that might be useful for others too. It makes the patchreview toolview's update button do something.

The BranchManager will have disappeared by the time users can press this button, so the source branch remains fixed. But since the diff is against the branch currently checked out, this change makes it possible to check out another branch (via the BranchManager or externally) and simply hit the button to update the diff. Saves a few clicks and probably some CPU cycles related to reloading and reparsing open documents too.

Test Plan

Tested on the 5.1 branch; works as expected.

This is a useful little change to the patch review plugin itself:

 void PatchReviewPlugin::forceUpdate() {
     if( m_patch ) {
-        m_patch->update();
+        // only trigger an update if the plugin can update itself
+        VCSDiffPatchSource *vcsPatch = dynamic_cast<VCSDiffPatchSource*>(;
+        if (!vcsPatch || vcsPatch->m_updater) {
+            m_patch->update();
+            notifyPatchChanged();
+        }
+    }

I like the feature. Thanks!

I'm pretty sure it wasn't implemented because the VcsDiff VCSDiffUpdater::update() API sucks, but I guess we can look into that in another iteration.

Rene, you submitted it to the wrong repository.

This should go to kdevelop.

I planned to do a 5.1 -> 5.2 branch merge and then realised I couldn't. It's been committed to kdevelop too.
