Scope down the new trigger-on-save behavior to only open-editor and
config-edit. Other uses of the editor such as edit-url and edit-command
will behave as before.
These are passing locally but failing in travis. This fixes two possible
timing issues:
- Ensure the signals are set up befor the pidfile is written. The
function that sends the signal waits for the pidfile to exist, so this
ensures we don't miss a signal.
- Wait for the log message indicating that the editor file was read
back, so the test doesn't run through before we get a chance to read
from the editor.
With the previous code, the editor could miss the final signal on a
save-and-exit. This is avoided by always running the file changed
handler on a successful exit, but only firing the signal if the content
actually changed (to avoid double-signalling).
Now that the editor signals on save, the configcommands editing
unittests need to emit the signal in the patch rather than relying on
on_proc_closed to emit the signal.
Now that the editor fires editing_finished on every write, the unit
tests had to be updated.
- Add qtbot to the editor fixture to resolve `QtWarningMsg:
QSocketNotifier: Can only be used with threads started with QThread`
- Use removePaths instead of disconnect to stop the watcher from
signalling. This avoids an error when the editor is forcibly cleaned
up by the tests without the signal ever being connected, but otherwise
has the same behavior as disconnecting the singal.
- wait for a signal on write instead of proc closed
- wait for _watcher.fileChanged in test_unreadable to ensure the write
event is fired before the test exits.
For any command that spawns an editor, tirgger an update on save, not
just on exit.
- :open-editor writes the text field on save
- :edit-url navigates on save
- :edit-url -t opens a new tab on each save
- :edit-command updates the statusbar text on save
- :edit-command --run runs a command on each save
- :config-edit reloads the config on save
Resolves#2307.
Helps mitigate #1596 by allowing users to 'save' partial work, and
notice if there was an error without closing the editor.
