Git commit 68094ed9b1295773e94094fd132820a21c4513ad by Toni Asensi Esteve. Committed on 10/03/2020 at 21:25. Pushed by asensi into branch 'master'. Solve what happens when F4 (or equivalent) is pressed on a remote folder In more detail: If F4 (or equivalent) is pressed on a remote folder, then an empty file is edited, and an error message is shown. Notes: This also happened before applying Manage what happens when a PanelViewerBase (e.g. using Shift+F3) tries to open a nonexistent local file https://phabricator.kde.org/D27258 or Manage the use of Shift+F4 when opening a local file that exists, or a remote folder or remote file that exists https://phabricator.kde.org/D27259 though some of the code that was introduced in https://phabricator.kde.org/D27259 was reused in the present code review. Test Plan: Using F4 to try to open a: - local file that exists: /etc/passwd - local folder that exists: /etc - remote folder: smb://user@IP_ADDRESS/PATH/EXISTENT_FOLDER - remote folder: fish://user@IP_ADDRESS:PORT/PATH/EXISTENT_FOLDER Using Shift+F4 to try to open a: - local file that exists: /etc/passwd - local folder that exists: /etc - remote folder: smb://user@IP_ADDRESS/PATH/EXISTENT_FOLDER - remote folder: fish://user@IP_ADDRESS:PORT/PATH/EXISTENT_FOLDER Performing the tests using the default internal editor and also /usr/bin/kate. Performing the tests using e.g. Kubuntu 18.04 LTS and Kubuntu 19.10.
