From f8cee78b734acf4636d134afa3f81ddcc06241e6 Mon Sep 17 00:00:00 2001 From: Scott Murray Date: Thu, 28 May 2020 15:06:33 -0400 Subject: Fix uninstall of widgets without icons Trying to uninstall a widget without an icon would remove the widget files, but report an error, and the widget would not be removed from the database until a reboot, preventing installation of a new version. To fix this, the error handling in uninstall_widget has been reworked to only explicitly return an error when the unlink of the icon file fails for reasons other than the file not being present. This then allows some code cleanup by removing the extra rc2 variable and fixing some error checks where rc and rc2 were being mixed.
