The original reason that the Qt picker was used instead of the native
picker was that the native option would cause Nautilus/GNOME-based
pickers to hang.
This turned out to be due with a Qt bug with parenting Gtk windows. As a
result the parent of each file dialog window has been set to NULL,
eliminating the crash. As far as tests have shown, this produces no
adverse effects on either floating or tiling wms.
Fixes#3494
Revert needed, since otherwise there is no way to do automatic sorting
of includes.
Also reverted change to the docs, as leaving it would make incorrect
docs.
In case of conflicts, includes were sorted according to the coding
standards from #3839.
This reverts commit b4a9f04f92.
This reverts commit 5921122960.
Importing a profile, saving a QR code image or setting an auto-accept directory using Nautilus as the default file manager, which many users use, was causing a hang in Qt's method. Setting Qt to use it's own file manager in this circumstance fixes the issue. Closes#3436, closes#3443.
qTox will automatically import the old history on startup.
This new database code is much more robust.
It is very resilient and will not corrupt or disappear after a crash or
power failure, unlike the old code.
The on-disk database format is also much more compact now.
The database sync option in the advanced settings has been removed,
we know run many database operations asynchronously so performance
should not be a problem anymore, but we always ensure resiliency
in case of abrupt termination, so there is no tradeoff anymore.
