When min_chars is nonzero, if the first command that opens the
completion has < min_chars on the word under the cursor, it triggers a
check for a condition where last_cursor_pos is None.
By setting last_cursor_pos=-1 we ensure that the completer always
updates the first time it is opened, and that there is never a check
against None.
This adds a test for the min_chars feature.
Resolves#3635.
shellcheck recently added SC2330 checking for this. "which" is non-standard, and
not guaranteed by POSIX to have a meaningful exit status, while "command -v" is
specified by POSIX: https://stackoverflow.com/q/592620
On some pages like Qt's Gerrit, Indiegogo or Telegram Web, this caused a crash
with QtWebEngine and Qt 5.10.1 in
QtWebEngineCore::WebContentsAdapter::webContents().
I'm not sure what causes the crash exactly, but I'm guessing it's some kind of
race condition between loading the URL initially and deserializing the history,
which both ends up loading the URL.
Since restoring the history means we end up on the given URL anyways, let's just
not open the URL beforehand, which seems to fix this.
Fixes#3619.
This is emitted when we know that we're going to visit some URL, but Qt doesn't
know yet. This way, we can change the settings early, and since we know which
settings have actually changed, prevent a change needing a reload in
_on_navigation_request.
This refactors the whole web(kit|engine|) settings mess a bit so there's a
Web(Kit|Engine)Settings object for (non-static) settings set on a
QWeb(Engine)Settings object in Qt. Everything else is set on module-level a bit
less declaratively.
The whole inheritance mess is gone, and we can now also construct a
Web(Kit|Engine)Settings object for a given tab.
Fixes#2701
