Without TLS (and thus ALPN/NPN negotiation) HTTP/2 requires
a protocol upgrade procedure, as described in RFC 7540, 3.2.
We start as HTTP/1.1 (and thus we create QHttpProtocolHandler first),
augmenting the headers we send with 'Upgrade: h2c'. In case
we receive HTTP/1.1 response with status code 101 ('Switching
Protocols'), we continue as HTTP/2 session, creating QHttp2ProtocolHandler
and pretending the first request we sent was HTTP/2 request
on a real HTTP/2 stream. If the first response is something different
from 101, we continue as HTTP/1.1. This change also required
auto-test update: our toy-server now has to respond to
the initial HTTP/1.1 request on a platform without ALPN/NPN.
As a bonus a subtle flakyness in 'goaway' auto-test went
away (well, it was fixed).
[ChangeLog][QtNetwork][HTTP/2] In case of clear text HTTP/2 we
now initiate a required protocol upgrade procedure instead of
'H2Direct' connection.

When a ObjC++ QObject subclass is listed in the regular HEADERS, qmake
creates a .cpp file. The moc file will then fail to compile, as it
requries ObjC++ headers. Using Q_FORWARD_DECLARE_OBJC_CLASS() can be
used to let the class be parsed by The compiler, but link will still
fail, as the generated methods (e.g. signals) must be built with ObjC++
compiler, in case they have ObjC parameters:
Q_FORWARD_DECLARE_OBJC_CLASS(NSString);
class MyClass: public QObject {
Q_OBJECT
signals:
void objcSignal(NSString * myObj);
};
The canonical workaround for that is including the .cpp file into the
corresponding .mm file. This also offers a compilation speed advantage,
but is somewhat counter-intuitive.
Therefore, we introduce a separate variable which instructs moc to create
.mm files directly.

By sharing the implementations of the methods between QNSWindow and
QNSPanel we don't need a helper, and can remove duplicated code. This
duplication would expand in the future, as for each method added to
the QNSWindowProtocol, we would have to add forwarding functions
in both QNSWindow and QNSPanel, forwarding to QNSWindowHelper, and
then two more functions in QNSWindow and QNSPanel in case we wanted
to call super from the helper, similar to [QNSWindow superSendEvent].
The only snag is that calls to super are hard-coded to a specific
superclass during complication, so we provide our wrapper for
objc_msgSendSuper that resolves the superclass at runtime.
The helper class QSendSuperHelper provides compile time implicit
instantiation of the right template without having to provide
the return type as a template argument, via operator T and
a fallback for the case of no return type via the destructor.

That means a file is never created, unless you ask for the name. There's
no chance of left-over temporary files being left behind. QSaveFile also
benefits from this, since the save file is not present on disk until

because linkat(2) cannot overwrite -- we need rename(2) for that (for
now).

not immediate:
- sendfile(2) can be used on regular files, even across mountpoints
- sendfile(2) can be used on block devices too, but we need to get the
device's size first
- splice(2) can be used on pipes (FIFOs)

This test sets up two timers:
- a 100ms recurring timer
- a series of 10 200ms single-shot timers.
After quitLock lets exec() return it then uses a signal
spy to check if the 100ms timer fired at least 17/20
of the times it should.
However there is no guarantee that the 100ms timer
will fire more often than the 200ms timer. If the
native timer callbacks happen at 500ms intervals then
Qt will fire both timers (once) at that interval.
In practice this seems to happen on macOS CI under
system load and/or with the test app napping.
The primary goal for the test is to verify that exec()
returns when it should; we can remove the timer signal
spy.
