This reverts commit 6cc920472ee4170b257a0b588687b175162e83df.
Since self._widget can go stale in the layout, we need to somehow solve this differently...
Closes#3875
The autoupdator, which uses `qutebrowser.misc.httpclient` has been failing recently because the URL that it hits to check version information is now serving a 301 moved permanently. By default QNetworkRequest doesn't follow redirects so it was getting back a (non-json, despite the request) body pointing to the new location, instead or version information. This changes fixes that by changing HTTPClient to use a QNetworkRequest subclass which follows redirects by default.
It lookes like HTTPClient is currently only used in autoupdate.py, version.py, and crashdialog.py so I don't expect any breakage.
5.6-5.8 Only had a boolean setting available which allows redirects, but not from the https scheme to http, 5.9 introduces a more nuanced setting. I have tested locally on 5.7.1 and 5.10.
`prefix` is a string and `seq` is a key sequence, so removing `len(prefix)`
items from `seq` will remove too many if `prefix` contains a special character
(ex "<Ctrl+x>"). Remove the number of characters from `str(seq)` instead.
- Use qutebrowser-editor-backup as the backup file prefix
- Consistently use message.error instead of cmdexc
- Improve test coverage for the backup function
- Fix lint errors in the unit test code
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
If we try to remove watched files but we couldn't actually watch any earlier,
we'd get a Qt warning message:
QtWarningMsg: QFileSystemWatcher::removePaths: list is empty
Added a --paste flag to the :version command and a JS button with corresponding qutescheme URL in the Version debug page to enable pastebinning version.
