Currently the editor deletes its temp file whenever editing is finished.
With this patch, the file will not be deleted if the editor callback
encounters an exception.
One example is if the tab containing the edited element is closed. The
editor errors with "Edited element vanished", but with this patch it
will also print "Backup at ..." so the user does not lose their work.
Resolves#1596.
Supersedes #3641, using the cleaner approach started in #1677.
With QtWebKit it's probably okay to still use it (*cough* Hyperbola
GNU/Linux-libre^tm *cough*), and only blacklisting it with QtWebEngine would be
quite some effort.
Fixes#3608
The test above this one loads hello.txt, but we don't wait for the "load
finished" message, so it can arrive after the previous test already finished and
make this test not wait properly.
However, we also can't easily wait for the load finished message in the
previous test as it only appears with QtWebEngine, not QtWebKit.
As a workaround, we simply load another file in that test, to circumvent this
kind of cross-interaction.
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.
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.
