19.07.3 regression: installing an app doesn't show in the menu unless logging out/in again

[jonglezb]

In 19.07.2, after installing a LuCI app, it started appearing in the menu as soon as you go to a new page.

In 19.07.3, the new app doesn't appear in the menu even after changing page. A logout and login is needed.

I tried the bootstrap theme and the following apps:

• luci-app-openvpn
• luci-app-nlbwmon

To reproduce:

• log in
• go to System / Software
• update lists
• install luci-app-nlbwmon
• go to (for instance) Status / Overview
• the "Bandwidth Monitor" menu still does not appear
• log out / log in : the menu now appears as expected

Yep, its a known issue which we cannot fix for 19.07.3 anymore. I added a note to the release notes. A fix will entail an update to luci-app-opkg which will flush the SessionStorage menu cache after a package install operation.

A workaround helped me:

/etc/init.d/uhttpd stop
rm -rf /tmp/luci-*
/etc/init.d/uhttpd start

Would it be enough to backport the (secondary) fix from dc57e4b ?

@zorun - yes, most likely. Not entirely sure if we'd need further backports in the dispatcher code wrt. server side cache invalidation

[zorun]

It turns out that simply backporting the fix is enough, see #4402

The fix is merged, thanks jow!
