Measurements show that it's just almost as fast to simply query
the connectionlist directly and avoid both the memory
overhead of the bitfield and the associated bookkeeping.
For connected signals, the difference is not relevant at all.
With a signal that was never connected, removing the bitfield will
cause signal emission to be ~2.5% faster. And if you ever disconnect
from a signal, the bitfields might not be accurate and this can
cause a major slowdown.
Here are some numbers to validate this. All times are measured
in ms for 100M signal emissions:

QString::midRef (as correctly used in both changed uses of QStringRef,

the invalid read is only outside the array it's scanning, not outside

The web sandbox restricts access to the local file system,
which means Qt needs new public API to provide such
access to applications.
This adds a new static, asynchornous getOpenFileContent()
function to QFileDialog, which will show a file dialog,
read the file contents once a file has been selected, and
finally call the user-provided callback with the selected
file name and file data.
auto fileReady = [](const QString &fileName, const QByteArray &fileContents) {
// Process file
}
QFileDialog::getOpenFileContent("*.*", fileReady);
This API can be expanded in at least two ways in the
future: allow reading multiple files, and allow file

From big-request specification:
"This extension defines a mechanism for extending the length
field beyond 16 bits. If the normal 16-bit length field of the protocol
request is zero, then an additional 32-bit field containing the actual
length (in 4-byte units) is inserted into the request, immediately
following the 16-bit length field."
Meaning that the request requires 4 additional bytes. This patch provides
a convenience API for calculating maximum request data size.
Besides fixing QTBUG-73044, it was also discovered that calculations
for xcb_image_put (in QXcbBackingStoreImage::flushPixmap) were wrong.
The code assumed that xcb_get_maximum_request_length() returns bytes,
but what it actually returns is length which is measured in four-byte
units. This means that we were sending 4x less bytes than allowed by
the protocol. Furthermore, use the actual 'stride' (bytes per line) value
when calculating rows_per_put. The new stride value was introduced
by 760b2929a3, but was not updated in
rows_per_put calculations.

Tidied up the existing float tests in the process.
(In particular, s/SUCCESS/PASS/ since that matches real test output.)
These verify that QCOMPARE() handles floats and doubles as intended.
Extended the existing qFuzzyCompare tests to probe the boundaries of
the ranges of values of both types, in the process.
Revised the toString<double> that qCompare() uses to give enough
precision to actually show some of the differences being tested there
(12 digits, to match what qFuzzyCompare tests, so as to show different
values rather than, e.g. 1e12 for both expected and actual) and to
give consistent results for infinities and NaN (MinGW had eccentric
versions for these, leading to different output from tests, which thus
failed); did the latter also for toString<float> and fixed stray zeros
in MinGW's exponents (which made a kludge in tst_selftest.cpp
redundant, so I removed that, too).
That's further complicated handling of floating-point types, so let's
just keep an eye on how expensive that's getting by adding a benchmark
test for QTest::toString(). Unfortunately, default settings only get
runs that take modest numbers of milliseconds (some as low as 40)
while increasing this with -minumumvalue 100 or more gets the process
killed - and I'm unable to find out who's doing the killing (it's not
QProcess::kill, ::kill or the QtTest WatchDog, as far as I can tell).
So results are rather noisy; the integral tests exhibit speed-ups by
factors up to 5, and slow-downs by factors up to 100, between runs
with and without this change, which does not affec the integral tests.
The relatively modest slow-downs and speed-ups in the floating point
tests thus seem likely to be happenstance rather than signal.
