50ec3252ac Do not move data around on insert neither
The while insertion logic will need further work to make it
more efficient. Currently it does use copy construction and
assignment for internal moving instead of move operations.

b99271caa6 Avoid expensive iterator calculations in append()
Avoid moving data inside the array to create free
space at one end. This is a performance bottleneck,
as it required quite a lot of calculations for every
insert. Rather reallocate and grow in this case,
so we only need to do expensive work when we reallocate
the array.

7eed57511a QArrayDataPointer: redesign (and simplify) growth policy
It looks like we can drastically simplify the way QADP grows without
sacrificing much:
1. append-only use cases should have the same performance as before
2. prepend-only use cases should (with the help of other commits) get
   additional performance speedup
3. mid-insertion is harder to reason about, but it is either unchanged
   or benefits a bit as there's some free space at both ends now
4. mixed prepend/append cases are weird and would keep excess free
   space around but this is less critical and overall less used AFAIK

Now, QList would actually start to feel like a double-ended container
instead of "it's QVector but with faster prepend". This commit should
help close the performance gap between 6.0 and 5.15 as well

As a drawback, we will most likely have more space allocated in mixed
and mid-insert cases. This needs to be checked

a9c52dbdf4 Fix qHash(QMultiHash)
The old code was trying to convert a multi hash to a QHash. While
that worked in Qt 5 it won't compile in Qt 6 anymore.

QHashCombineCommutative also can't be used with a std::pair.
ADL won't find the correct instance with a namespaced build,
as qHash(std::pair) is defined after QHashCommutative. Fix
the code to compile and work correctly.

a31dde22db QProperty: Fix notification logic for eager properties
This ensurse that we do not do dobule notifications in setValue.
Moerover we avoid needless notifications in markDirtyAndNotifyObservers
when the value did not change. Lastly, if the value did actually change,
we pass that information along to notify, so that we do not evaluate the

Fixes a test-case which errorneously relied on the old behavior, and
adds a new test which verifies that the fix works.

c1c991c319 Remove std::function from QProperty interface
std::function as a type is rather unfortunate for us, as its SSO buffer
makes it rather large, and we can ensure that the function is never
empty.
Considering that we do need to allocate memory for
QPropertyBindingPrivate anyway, we can get rid of the SSO buffer and
instead coalesce the allocations (similar to how std::make_shared works).
The memory looks then like
[--QPropertyBindingPrivate--][Functor]
and QPropertyBindingPrivate can get a pointer to the functor via
reinterpret_cast<std::byte>(this)+sizeof(QPropertyBindingPrivate).
To actually do anything with the functor, we do however need a "vtable"
which describes how we can call, destroy and move the functor. This is
done by creating a constexpr struct of function pointers, and storing a
pointer to it in QPropertyBindingPrivate.

As a consequence of those changes, we cannot use QESDP anymore, as we
now have to carefully deallocate the buffer we used for both the
QPropertyBindingPrivate and the functor. We introduce a custom
refcounting pointer for that. While we're at it, we make the refcount
non-atomic, as bindings do not work across threads to begin with.

Moreover, we can now make the class non-virtual, as that was only needed
to hack around limitations of QESDP in the context of exported symbols.

3a1bc4bad5 Purge deprecated language and country codes from QLocale
Requires subsequent re-numbering of the enum tables to eliminate gaps,
before locale data can be regenerated. However, it will work with the
present locale data, since it merely loses the means to use some names
for which the available data was just the name and code. This implies
a transient issue of recognising some codes for which there is no
actual enum member; but relevant code will work as before, finding
nothing but the code and its name. This shall be resolved by a coming
BiC change to resort the language, country and script codes, changing
the numbering (almost) completely.

codes have been removed. Some lacked locale data, others were obsolete
aliases. All have been deprecated in 5.15.

The template gets always instantiated in QObjectPrivate::connect, even
if the connection types is not Qt::(Blocking)QueuedConnection. For
non-queued connections we however support using incomplete types in
connect. The only way to fix this would be to make the connection type a
template parameter of QObjectPrivate::connect (or at lesat pass some
compile time constant indicating "blocking"-ness) along, so that we can
use if constexpr instead of if. As all involved classes are private, we
can postpone investigating this solution to 6.1

21d3916817 QRandomGenerator: add 64-bit bounded() versions
Unlike the 32-bit version, we can't go to a bigger integer type to do
the multiplication with. So instead accept looping. Both libstdc++ and
libc++ implement std::uniform_int_distribution this way anyway, but in a
far more complex way.

There is no looping if the "highest" is a power of two. The worst-case
scenario is when "highest" is one past a power of two (like 65). In that
case, we'll loop until the number is in range. Since all bits have equal
probability of being zero or one, there's a 50-50 chance that the most
significant useful bit will be set[*], in which case we'll need to loop
and we again get the same probability. So on average, we only need two
iterations to get an acceptable result.

[*] There's also a possibility that the other bits are such that the
number is still in range. For 65, we'd need the other 5 bits to be zero
(64 is a valid result), but the probability of that is only 1/2^5 =
3.125%. The bigger "highest" is, the closer we get to zero, so
approximate by saying that never happens and instead calculate that the
most significant useful bit is the controlling one.

[ChangeLog][QtCore][QRandomGenerator] Added 64-bit versions of the
bounded() functions. They are useful in conjunction with Qt 6's 64-bit
container sizes, so code that used to call bounded(list.size()) in Qt 5
will continue to compile and work in Qt 6.

37c7ef4f4a QMetaContainer: Consistently coerce types
The high-level iterable interfaces should coerce the types of most
QVariants passed to the expected ones. To do this, move the type
coercion code into qvariant.{h|cpp} so that it is available to the
QVariantRef specializations.

The exception are variants passed to the find() functions of associative
iterables. Here, we should not coerce values we cannot convert to the
default-constructed keys. Instead we return end() in such cases.

by the macro, but the last three weren't. Save uses of the macro the
need to repeat the prefix in all parameters, thereby making the test
cases easier to read. Also, we can compare enum values, rather than
casting them to int; and, when a test fails, reporting the enum name
is far more informative than reporting the integer that represents it.

d4b206b246 Split QMutex and QRecursiveMutex
These classes should not inherit from each other
anymore in Qt 6. The reason is that this makes
the 95% case of using a non-recursive mutex
much slower than it has to be.

This way, QMutex can now inline the fast path
and be pretty much as fast as QBasicMutex is
in Qt 5. They actually use the same code paths
now. The main difference is that QMutex allows
calling tryLock() with a timeout, which that
is not allowed for QBasicMutex.

recursive locking anymore. Use QRecursiveMutex for that
purpose. QRecursiveMutex does not inherit QMutex anymore

fa93f1aeb0 Fix compile time type normalization code
Use a simpler constexpr to generate type name on gcc This
works around an ICE on gcc in release mode when compiling
with PCH enabled. As the type we're getting from Q_FUNC_INFO is
already in a somewhat normalized form, this requires significanlty
less processing and esp. not a recursive constexpr method which
I suspect triggers the ICE.

Fix integer type conversions to also properly normalize long long
values (to q(u)longlong. Make sure the mapping also works on
MSVC, where long long types get mapped to __int64. Also, normalize
unsigned short and unsigned char to ushort and uchar, respectively, to
follow the convention set by uint and ulong.

b83225fcc3 qDebug: Avoid implicit QVariant conversion
This commit restricts operator<<(QDebug lhs, QVariant rhs) to only work
if rhs is actually of type QVariant (instead of any type convertible to
QVariant). This is especially important as
a) we check in QMetaType whether (slightly simplified) QDebug{} <<
   std::declval<T>() is valid, and if so, register a function which
   simply uses the operator.
b) In QVariant, we ask the metatype system for the contained types
   registered debug function and then use it.
If a type now does not have its own operator<< for QDebug, but is
implicitly convertible to QVariant containing itself, this would lead to
an infinite recursion, when trying to use qDebug with that type. The
registered function in a) would just convert the type to QVariant, and
then ask the QVariant to print itself.
Disallowing implicit conversions in qDebug in general was considered
(i.e. adding template<typename T> operator<<(T) = delete in QDebug ),
but discarded as it breaks too much code relying on conversions.

Corrected some tests that wrongly expected to be able to represent
extreme date-time values with every time-spec.  The (milli)seconds
since epoch are from UTC's epoch, so converting to another offset,
zone or local time may give a value outside the actual range.  Added
some tests for the actual exact bounds.

e5dc46d966 Allow millisecond-overflow when the result remains valid
Even before adding support for fractional hours, a fraction of a
minute might potentially have represented a whole number of seconds by
a fractional part that, due to rounding, was less than the whole
number of seconds by less than half a millisecond. Previously, the
parsing would have clipped the fractional part at 999 milliseconds, in
the preceding second, instead of correctly rounding it up to the whole
second.

For QTime::fromString(), which can't represent 24:00, and for
TextDate, which doesn't allow 24:00 as a synomym for the next day's
0:0, applying such rounding to 23:59:59.999999 would produce an
invalid result from a string that does represent a valid time, so use
the nearest representable time, as previously.

Added some tests and amended others.

[ChangeLog][QtCore][QDateTime] QDateTime and QTime, in fromString()
with format ISODate or TextDate, now allow a fractional part of the
hour, minute or seconds to round up to the next second (hence
potentially into the next minute, etc.) when this is the closest
representable value to the exact fractional part given. When rounding
up would turn a valid result into an invalid one, however, the old
behavior of clipping to 999 milliseconds is retained.

normalize (the above becomes "file://x/y").

4e675cb85e Handle trailing cruft consistently in Qt::DateFormat parsing
Previously the ISO time format would tolerate trailing cruft at the
end in various cases even though there might be an offset specifier
after the time, which should *not* be separated from it by anything
(not even the spaces we originally planned to still tolerate).

The RFC date format is forgiving about space, as is suitable for
parsing of RFC-822 headers, but the other formats should match the
handling in QDateTimeParser, which rejects any dangling cruft.

At the same time, since this required a re-write of
fromIsoTimeString() in any case, add support for the ISO format that
gives the hour a fractional part and skips minutes and
seconds. Previously we only had support for fractional minutes (with
no seconds). The hour without even a fractional part is also valid.

Reworked the documentation of Qt::DateFormat as it was wrong in
places, inconsistent in its formatting and incomplete. Adjusted some
tests to match the new behavior. A fraction separator with no
following digits should have been recognized as an error previously
and now is.

[ChangeLog][QtCore][QDateTime] The ISODate and ISODateWithMs formats

b1cf188e83 Rework a test, eliminating some needless conversion via strings
The name toSecsSinceEpoch() gave no hint to the fact that the test
was, in fact, *also* testing round-tripping of the ISODateFormat.
Since there are other tests for string conversion, make this a simple
test of toSecsSinceEpoch().

It did the round-tripping via two methods with overly-terse names that
might just as well be local lambdas - now redundant, so removed.

1c591fd924 Deal with {und,ov}erflow issues in QLine's length handling
Use std::hypot() instead of sqrt() of a sum of squares.
This ensures length() can't be zero when isNull() is false.
Use length() in QLine::setLength() rather than duplicating that.

Clarify and expand some documentation; isNull() never said what
constituted validity, nor did unitVector() mention that is should not
be used on a line for which isNull() is true. Make clear that lines of
denormal length cannot be rescaled accurately.

Given that we use fuzzy comparison to determine equality of
end-points, isNull() can be false for a line with displacements less
than sqrt(numeric_limits<qreal>::denorm_min()) between the coordinates
of its end-points (as long as these are not much bigger); squaring
these would give zero, hence a zero length, where using hypot() avoids
the underflow and gives a non-zero length. Having a zero length for a
line with isNull() false would lead to problems in setLength(), which
uses an isNull() pre-test, protecting a call to unitVector().

(It was already possible for a null line to have non-zero length; this
now arises in more cases.)

Restored QLine::setLength() to the form it had before a recent change
to avoid division by zero (which resulted from underflow in computing
the length of a non-null line) but allow for the possibility that the
unit vector it computes as transient may not have length exactly one.

Add tests against {ov,und}erflow problems in QLine. Reworked the test
added during the divide-by-zero fix to make it part of the existing
test.

8572f84467 Fix ChangeHandler notification for eager properties
ChangeHandler's evaluated the binding to detect if the value actually
changed. This is a valid strategy for lazy bindings, but eager bindings
were already evaluated at that point, and thus the change would not be
detected.
Change the binding loop test, so that there isn't a fixpoint in the
binding loop, and we can still detect it. Changing the binding loop
detection code to deal with this case is left as an exercise for the

ac7e518a64 [QtCore] Fix QDateTime unit test: time zone of system was used
Test data for QDateTime unit tests was constructed in system's local
time, which made unit test outcome dependent on the time zone of the
system running the tests.
This led to failing unit tests on systems with libc6 version
2.31 or newer. A QDateTime in a timezone, which has daylight saving
time, was created and then used in Hawaii's time zone,which has no
daylight saving time. Newer glibc checks this and returns errors.
This patch changes the behavior to create the test data in a
specified time zone setting.

b5234817f1 Introduce QProcess::startCommand(QString, OpenMode)
The removal of the QProcess::start(QString, OpenMode) leads to more
porting work than anticipated. A call like

    QProcess p;
    p.start(cmdline);

must be transformed in the following cumbersome way:

    QProcess p;
    QStringList args = QProcess::splitCommand(cmdline);
    QString program = args.takeFirst();
    p.start(program, args);

This patch revives QProcess::start(QString, OpenMode) and renames it to
QProcess::startCommand. This is still source-incompatible, but the
transformation is much simpler:

    QProcess p;
    p.startCommand(cmdline);

[ChangeLog][QtCore][QProcess] Added QProcess::startCommand(QString,
OpenMode) as replacement for the removed QProcess::start(QString,
OpenMode).

db3d5a3097 Fix flaky QTimer::remainingTime() test
Before, we used not so accurate QTest::qWait(50)
to measure the accuracy of more precise timer's interval.
In addition, the checked range for remainingTime (50, 200)
was probably wrong, since by definition it couldn't be more than 150,
as we started the timer with interval of 200 and waited at least 50.

In this fix we have additional "tester" timer to measure remainingTime
of "tested" timer. The "tester" is a singleShot timer with interval of
50, and is started together with "tested" timer. Whenever the "tested"
timer timeouts, it restarts the "tester" timer - this is done desired
number of times (2 by default, like in the original test).

The test itself lies now inside tester's lambda. We fix the tested
range (at least 1, no more than 150). The minimum value could in
theory be greater, but it's enough to test that it's not overdue.

Finally, we wait for expected number of test runs. We give it twice
as much time as is in theory needed.

7e93870401 QProcess/Unix: introduce setChildProcessModifier()
[ChangeLog][Source-Incompatible Changes] QProcess::setupChildProcess()
was removed. To execute code in a child process, use
QProcess::setChildProcessModifier()

[ChangeLog][QtCore][QProcess] Added setChildProcessModifier() function
with which one can provide code to be run in the Unix child process
between fork() and execve(). With this function, it is no longer
necessary to derive from QProcess in order to execute actions in the
child process.

Another reason is that we can tell whether the std::function carries a
valid target much more easily than we can tell whether QProcess was
overridden.

The setupChildProcess() virtual function does not need to be marked
final, since no overrider could ever return an inaccessible private
class. This also makes sure the error presented to the user is about the
return type, not about attempting to override a final.

Clang:
 error: virtual function 'f' has a different return type ('void') than the function it overrides (which has return type 'QProcess::Use_setChildProcessModifier_Instead')

GCC:
 error: conflicting return type specified for 'virtual void MyProcess::setupChildProcess()'
 note: overridden function is 'virtual QProcess::Use_setChildProcessModifier_Instead QProcess::setupChildProcess()'

ICC:
 error: return type is neither identical to nor covariant with return type "QProcess::Use_setChildProcessModifier_Instead" of overridden virtual function "QProcess::setupChildProcess"

MSVC is not relevant since it doesn't compile to Unix.
