Moves all the stuff that is needed to start DBus on macOS (which for some reason it needs several steps, involving the use of `launchctl`) into a single `startDBusDaemon()` function. Before, it was spread into `kdeconnectconfig.cpp`, `indicatorhelper_mac.cpp` and `dbushelper.cpp`.
It also removes checking for an existing DBus daemon and always starts our own, since in most cases we couldn't connect to it anyway. This, together with removing the sleep in the retries when polling for the DBus daemon from 3s to 100ms, makes the startup much faster, so I removed the loading splash screen.
Auto reconfiguration of own certificate:
currently:
if kdeconncectd loads its certificate and its expired or not effective yet
it generates a new certificate
previously:
if kdeconncectd loads its certificate and its expired or not effective yet
it continues having the same certificate
This brings forth an issue: Other devices would refuse to connect to a device with
an expired or non-effective certificate.
Auto-delete of orphan certificates:
currently:
Devices in kdeconnectd's devicelist that have illegal ssl certificates
(expired, not effective yet, empty) get automatically deleted from the
devicelist
previously:
they would just exist forever until the user deletes them
A year does not have 356 days:
currently: int a_year_in_seconds = 365 * 24 * 60 * 60;
previously: int a_year_in_seconds = 356 * 24 * 60 * 60;
Use smaller and safer EC keys, replacing 2048 bit RSA.
NID_X9_62_prime256v1 is roughly as secure as a 3072 bit RSA key, but way shorter.
Since we have to embed the key in the identity packet that is sent over UDP and
some stacks aren't happy with large UDP messages (notably: macos), I switched to
EC instead of to a longer RSA key.
This seems to be compatible with other clients even on older systems like Android 5.0.
I did stick with NID_X9_62_prime256v1 because stronger EC like NID_secp384r1 failed
the handshake (I didn't investigate why).
We now store the kind of key in the config, so we can know which kind of key we are loading.
Better patch to replace !218.
- Auto and quick detection of previous D-Bus instance;
- Remove private D-Bus compile definition, only use it on macOS without an existing D-Bus instance;
- Safe reboot after crashes because the indicator is not relating on the kdeconnectd to run a D-Bus session;
- Safe exit after clicking on `Quit` in the systray.
More details in commit logs:
Only enable private D-Bus on macOS because the other platforms do not
need them.
The app should be able to easily detect the session bus from the env
DBUS_LAUNCHD_SESSION_BUS_SOCKET from launchd through launchctl.
Because https://gitlab.freedesktop.org/dbus/dbus/-/blob/master/dbus/dbus-sysdeps-unix.c#L4392
shows that it is the only probing method on macOS with launchd.
The D-Bus session bus can be easily found from launchd/launchctl
with DBUS_LAUNCHD_SESSION_BUS_SOCKET env. It can be an external one
(installed from HomeBrew) or an internal one (launched by a previous
instance followed by a crash).
The indicator helper on macOS can now automatically detect whether we can use a potentially
(with launchd/launchctl env set, or KDE Connect macOS
private_bus_address set) existed and usable session bus.
If previous bus is usable, just try to launch the kdeconnectd with us.
Otherwise, launch a private D-Bus daemon, export the launchd/launchctl
env, and run a kdeconnectd instance.
Everything works better and quicker now :)
Summary:
Change all member variables to the form m_fooBar because it is the preferred form in Qt (it was half and half between this and mFooBar, and a minority didn't have anything).
Place all references and pointers on the side of the type since it is the majority.
Basically:
- mFoo -> m_foo
- foo -> m_foo (if it is a member variable)
- Type &ref -> Type& ref
- Type *ptr -> Type* ptr

Centralizing the plugins' config will ensure that all the plugins store it
the same way (ie: not in random files scattered around, like until now).
The base KCM class, together with the already existing base plugin class,
will give easy access to all the plugins to this centralized config. Also,
now the settings are not shared across devices (that is: every device can
have different config for a same plugin).
Note: This commit requires KCMUtils 5.9
REVIEW: 122927
Benefits:
- We had config files in different paths, now they will be centralized.
- Daemon, LanLinkProvider and NetworkPackage depend only on Qt now.
- KConfig is accessed with strings as keys, where a typo can go unnoticed.
- Daemon is now thinner, as it doesn't need to initialize config values.
- QCA::Initializer is in a single place now (was in Daemon and Plugin).
