While a native dialog is open, the application message queue is
handled by the native event loop which is external to Qt. In this
case, QEventDispatcherWin32::processEvents() does not run and socket
notifiers will not be activated. So, this patch moves the notifier
activation code into the window procedure, which enables socket
event processing with native dialogs.

The use of QPair made the return type of initializeAnimation()
so complicated, that the original author opted to declare the
pair on one line, then assign to it in the next, to keep below
the line length limit.
She also copied a member of the pair just so as to give it a
descriptive name.
Fix both by introducing a small result struct. It has a nicer
name, compared to the pair, but still port callers to use 'auto'.
The member names are descriptive enough now.

...to turn mutable lvalues into const lvalues.
Like the proposed std::as_const, it should not apply to
rvalues to avoid lifetime issues in code like
for (auto x : qAsConst(someFunc()))
// dangling
At a more basic level, qAsConst isn't useful for rvalues,
because one can always store them in an lvalue first, with
no loss in performance (the object is created by the
compiler silently anyway). So the correct way to write the
above is:
const auto funcResult = someFunc();
for (auto e : funcResult)
To fail compilation when passing rvalues, I used the
const-&& pattern also employed by std::cref(), and the
proposed std::as_const.
Intended as internal API, but not put into the QtPrivate
namespace to make it simpler to use.
We could wait for std::as_const, but that is far, far
away (just entered the current C++17 draft as of this
writing), and the Qt containers with their tendency to
detach are a problem _now_.

The old code re-used a QFileInfo object, repeatedly
setting new file names with QFileInfo::setFile(QString).
But QFileInfo::setFile() simply assigns itself a
new QFileInfo object:
*this = QFileInfo(...)
so it's just as efficient to re-create a new QFIleInfo
object for every file name under test.
To avoid extra {} for object lifetime scoping, factor
the repeated evaluation of isReadable() && isFile()
into a small helper function, which also creates and
destroys the QFileInfo object.
The deeper significance of this change is that it
avoids implicit sharing of 'realname', which is
permanently modified. A later patch will make
changes that make 'realname' re-use its capacity
through the lifetime of the find_translation()
function, and sharing the variable implicitly will
nip any auch attempts in the bud.
Force the compiler to not inline the new function.
There's really no point in spending ~0.5KiB in text
size on inlining the code; the miniscule speed
improvement is dwarfed by the memory allocation of
the QFileInfo ctor, anyway.
As a consequence, this change even saves 96b in text
size on optimized GCC 4.9 Linux AMD64 builds, even
though that wasn't even the goal.

If FILE refers to a JSON file and latter was updated, then the expected

The qt_poll function calls recv to query whether fds marked by select
as readable should be marked POLLIN or POLLHUP in the pollfd structure.
On many platforms such as QNX this requires extra link-time libraries
which were not previously required by QtCore.
While the qt_poll function is intended as a fallback mechanism only for
those platforms which do not implement poll natively, the function was
compiled unconditionally whenever QT_BUILD_INTERNAL was defined, e.g.
in developer builds.
Additionally the function was included on those systems that define poll
in system headers so that configure determines build-time availability,
but do not define _POSIX_POLL > 0 or indicate POSIX:2008 compliance via
either the _POSIX_VERSION or _XOPEN_VERSION macros. On those systems a
sysconf query for _SC_POLL was performed to determine at runtime whether
to call the system poll or qt_poll.
Both of these cases are in fact counterproductive. In the first case the
sole consumer of the function is a single manual unit test. In the
second, to my knowledge no platform requires the runtime fallback.
Despite that, we were forcing an extra dylib in both cases.
Both cases are fixed by 1) moving the implementation into its own file
for the unit test to include and 2) dropping the dynamic fallback if
configure determines availability of poll at compile-time.
This also reverts commit 1377709711, which
added -lsocket for QtCore on QNX.

This should solve problems with our use of the noexcept
operator, because that's how std::pair is defined, too.
Mid-term, we should kill QPair and use std::pair instead.
It really has gotten way too complicated to implement a
C++11 pair correctly.

In C++, signed overflow math is Undefined Behavior. However, many CPUs
do implement some way to check for overflow. Some compilers expose
intrinsics to use this functionality. If the no intrinsic is exposed,
overflow checking can be done by widening the result type and "manually"
checking for overflow. Or, for X86, by using inline assembly to use the
CPU features.
Used in QtQml.

Opt-in by setting

This will make QCoreApplication and QThread create
a QEventDispatcherCoreFoundation instead of a
QEventDispatcherUNIX.
With this change we can now support calling native API
that requires a running Core Foundation event loop
on the QCoreApplication main thread and secondary
threads. Previously this was only supported on the
QGuiApplication main thread.
Rewrite the #ifdef event dispatcher logic slightly:
both OSX and GLIB now gets an "else" branch for the
UNIX event dispatcher, instead of the current "dangling

can be marked as nothrow.
Technically, the function doesn't have a wide
contract, because it has the precondition that
the buffer pointed to by the first argument needs
to be large enough to hold the result.
But that precondition can't be checked from within
the function, so no failure can be generated for
it and thus the nothrow guarantee is acceptable
(and desireable).

Not only do we not allocate memory anymore, we even

In order to preserve behavior with the previous code,
which consumed all digits before performing error
checking on them, we also consume all digits, even if

The behavior from before libdouble-conversion is that in case of an
overflow the OK flag is set to false, but the returned number is still
infinity, rather than 0. Also, the number of processed characters is
always set to the number of characters actually processed, unless
garbage is found.
There is an important distinction between an overflow and garbage. The
client code may accept overflows and infinity may be a valid result.
Garbage is most certainly not acceptable. Having an infinity/false result
in addition to 0/false allows the client code to distinguish those.
One application where this is useful is parsing JavaScript.
