Smooth shutdown #4109

tobiasdiez · 2018-06-06T14:32:42Z

I tried to remove the System.exit call so that JabRef shutdown smoothly. However, currently an AWT-thread does not want to exit. In order to solve this problem, I removed most calls that would init the AWT toolkit. This includes:

Use JavaFX clipboard instead of AWT
Remove L&F and font customization

Moreover, the Azure telemetry SDK has a bug microsoft/ApplicationInsights-Java#662 that prevents certain threads from terminating. I added the workaround mentioned in this issue.

Change in CHANGELOG.md described
Tests created for changes
Manually tested changed features in running JabRef
Screenshots added in PR description (for bigger UI changes)
Ensured that the git commit message is a good one
Check documentation status (Issue created for outdated help page at help.jabref.org?)

Looks good so far. I just added some comments that came to my mind.

src/main/java/org/jabref/JabRefGUI.java

-            }
+        // On Linux, Java FX fonts look blurry per default. This can be improved by using a non-default rendering
+        // setting. See https://github.com/woky/javafx-hates-linux
+        if (Globals.prefs.getBoolean(JabRefPreferences.FX_FONT_RENDERING_TWEAK)) {


Is there a Linux switch anywhere?

Yes, it is turned on by default only on Linux: defaults.put(FX_FONT_RENDERING_TWEAK, OS.LINUX);

src/main/java/org/jabref/gui/ClipBoardManager.java


    private static final Logger LOGGER = LoggerFactory.getLogger(ClipBoardManager.class);
+    public static final DataFormat XML = new DataFormat("application/xml");


Is this used anywhere?

Yes, when we put xml in the clipboard (which may happen for copied citation styles)

We have already a class DragAndDropDataFormats, maybe you could rename that and add it to the collection?

I don't want to interfere with your PR (especially, since I think it might completely remove the DragAndDropFormats class or make it internal to the DragAndDropManager).

src/main/java/org/jabref/gui/actions/CopyVersionToClipboardAction.java

-import org.jabref.logic.l10n.Localization;
-import org.jabref.logic.util.BuildInfo;
-
-public class CopyVersionToClipboardAction extends AbstractAction {


Functionality totally removed?

There is still a "copy version" button in the about dialog but no separate menu entry. (I didn't change anything as part of this PR; this class was completely unused).

stefan-kolb · 2018-06-06T17:45:44Z

src/test/java/org/jabref/gui/ClipBoardManagerTest.java

-
-public class ClipBoardManagerTest {
-
-    private ClipBoardManager clipBoardManager;


What about the tests?

The clipboard manager needs to run on the JavaFX thread to work, which is not easily achieved in a test. Thus, deleting these tests was easier than trying to rewrite them ;-)

I created a branch from master, cherry picked 39e30cc, and deleted all system.exit() calls.
It works fine for me. For reference, I have created a PR to show the diff: #4111

stefan-kolb

So we use this insetad of the PR of Christoph?!

+            client.flush();

+            // Workaround for bug https://github.com/Microsoft/ApplicationInsights-Java/issues/662


Add FIXME so we can revert this after they merged the bug fix.

I really would use my PR as a base. As this done does more than the initial necessary solution.

I don't understand the complication (including merge conflicts) but well it doesn't really matter. @Siedlerchr @stefan-kolb can I merge this PR?

And removing setting the font size without providing an alternative was not the good idea!

stefan-kolb · 2018-06-14T11:21:04Z

Just revert If necessary. Christoph <[email protected]> schrieb am Do., 14. Juni 2018, 12:28:

Sorry, I was so used to failing tests against the maintable-branch that I ignored the red travis icon. Tests are now fixed in master.
