Datei Versionen vergleichen

6ab310a0b7a6002defc1 · August 3, 2026, 5:43pm

Hallo Zusammen,

ich habe gerade ein seltsames Verhalten beobachtet beim Vergleich von Datei-Versionen. Und wollte mal hören, ob jemand das auch nachvollziehen kann.
Und zwar braucht man dazu nur eine Datei, z. B. Office oder Markdown, die schon mindestens einmal verändert wurde. In den Details klickt man nun in den Versionen bei einer Version, die nicht die letzte ist, im ‘…’-Menü auf “Mit aktueller Version vergleichen”. Eigentlich sollten dann beide Versionen nebeneinander aufgehen.
Ich habe das auf drei verschiedenen Nextcloud-Servern (auf verschiedenen Maschinen) ausprobiert, mit unterschiedlichem Ergebnis:

NC V32.0.12: Hier passiert, was zu erwarten ist: Beide Versionen öffnen sich nebeneinander.
NC V33.0.7: Nur eine Datei geht links auf, rechts dreht dauerhaft die Sanduhr.
NC V34.0.2: Nur eine Datei geht links auf, rechts dreht dauerhaft die Sanduhr.

In der nextcloud.log ist dazu selbst auf Debug-Level kein Eintrag. Und in der Nginx access.log finde ich auch keine Auffälligkeiten.

Da das unkompliziert und schnell auszuprobieren ist, wollte ich fragen, ob andere das Verhalten bei der V33 oder V34 nachvollziehen können, bevor ich einen Issue erstelle.

Danke.

Gruß
Jason

Vielen Dank!
Das nimmt mir einiges an Sorgen und Arbeit ab. Ich habe gerade so viel bei uns umgestellt, dass ich mir nicht mehr sicher war, ob es an mir (unserer Konfiguration) liegt, oder tatsächlich ein reproduzierbarer Fehler ist.
Dies ist so ein Moment, wo ich richtig glücklich bin, dass die Nextcloud eine so gute Community hat.
