104a0a9ecd Long live Q_(U)INT128_MIN/MAX!
Since compilers don't provide such macros, do it ourselves.

In order to test these macros, add ad-hoc specializations of
QTest::toString() for qint128 and quint128 locally to the test. Turns
out it's not too hard to write them, so we might move them to a public
header, yet.

6da6a17de9 Fix qHash(qfloat16) to match Qt 6.4 behavior
There were two problems:

- On platforms where QFLOAT16_IS_NATIVE == true, a qHash(qfloat16{})
  call has become ambiguous between the three FP qHash() overloads
  (float, double, long double), where it was unambiguously calling the
  float one in Qt 6.4. This SiC was caused by the replacement of
  operator float() by operator __fp16() in
  99c7f0419e, which is in Qt 6.5.

- On platforms where QFLOAT16_IS_NATIVE == false, qHash(qfloat16{})
  would produce a different value from qHash(float{}), and therefore
  Qt 6.4, when the seed was != 0, because the former would go via the
  one-arg-to-two-arg qHash adapter while the latter one would
  not. Since participating functions are inline, this causes old and
  new code to produce different hash values for the same qfloat16,
  leading to a BiC possibly corrupting QHash etc.

Fix both by adding an explicit qHash(qfloat16). This function is
inline, so it doesn't add a new symbol to 6.5.x.

[ChangeLog][QtCore] Fixed qHash(qfloat16) which was broken from 6.5.0
to 6.5.3, inclusive. If you compiled against one of the affected Qt
versions, you need to recompile against either Qt 6.4 or earlier or
6.5.4 or later, because the problematic code is inline.

9c63667d01 tst_QHashFunctions: fix std::pair test to use QFETCH_GLOBAL seeds
Because the local `seed` variable shadowed the member one, this test
was run for each QFETCH_GLOBAL with the same data and seed. That
doesn't make sense, so make the test use the member variable `seed`,
as all other tests already do.

Since zero is one of the seeds coming from QFETCH_GLOBAL, drop the
seedless calls to qHash(), too.

8ca319a172 tst_QHashFunctions: test with actual 64-bit seeds
The old code only tested with seed = 0 and seed = 1045982819, the
latter being a "random number", which, however, fits into
32-bits. Since Qt 6.0 increased the seed from uint to size_t, amend
the test to actually test a seed value with some of the upper half of
bits set, too, also in 64-bit mode.

While we're at it, also test with each seed's bits flipped for extra
coverage.

Remove a static assertion that prevented testing seeds with the MSB
set.

3db9ef358d QArrayDataPointer: remove Q_CHECK_PTR in assign(it, it) again
This commit reverts 2d77051f9d.

When requesting an allocation of size 0, we will actually get
a nullptr.

 qarraydata.cpp:
    ~~~
    if (capacity == 0) {
        *dptr = nullptr;
        return nullptr;
    }

This will let the Q_CHECK_PTR trigger falsely. Such an occurrence was
initially detected during the cmake_automoc_parser build-step.

QStaticLatin1StringMatcher is a static templated Latin-1 Boyer-Moore
string matcher which can be case sensitive or not. It should be used
when the needle is known at compile time so there is no run-time
overhead when generating the skip table.
The convenience functions qMakeStaticCaseSensitiveLatin1StringMatcher
and qMakeStaticCaseInsensitiveLatin1StringMatcher should be used to
construct the matcher objects.

Green Hills Optimizing Compilers are currently not supported.

b134718c11 QString: use new assign() in operator=({QByteArray, QChar, char *})
operator=(~) and assign() share similar names but, until now, have not
shared the same functionality. This patch introduces the usage of
QString::assign() within the non-sharing assignment operators to
effectively boost efficiency by reusing the available capacity.

Since we're re-using the capacity we update the test case in places
where they don't hold true anymore.

Since these assignment operators are frequently used in many places,
both within Qt and non-Qt code, this patch comes with benchmarks.

The preview of the benchmark results are compared with this patch and
before this patch. The results show a boost in performance for the
QByteArray and 'const char*' overload. The QLatin1StringView overload
already preserved the capacity and has a better performance than the
assign() alternative, so don't us it there.

961620824c QArrayData: make calculateBlockSize() account for the extra null element
Instead of adding it after the block size was calculated. This makes no
difference for non-growing (exact) blocks. For growing blocks, this
means we take that extra element into account before rounding to the
next power of two, instead of after. That results in a change of the
thresholds of when a block grows and also what capacity it will
contain.

For example, for a QString growing to 22-25 elements:

      Request     |       Previously        |           Now           |
elements |  bytes | malloc()ed | capacity() | malloc()ed | capacity() |
    22   |    44  |        66  |        24  |        64  |        23  |
    23   |    46  |        66  |        24  |        64  |        23  |
    24   |    48  |        66  |        24  |       128  |        55  |
    25   |    50  |       130  |        56  |       128  |        55  |

To avoid wasting elementSize - 2 bytes in this footer, we only include
this footer if elementSize <= 2. Thus, for a QList<int> growing to 11-13
elements:

      Request     |       Previously        |           Now           |
elements |  bytes | malloc()ed | capacity() | malloc()ed | capacity() |
    11   |    44  |        66  |        12  |        64  |        12  |
    12   |    48  |        66  |        12  |       128  |        28  |
    13   |    52  |       130  |        28  |       128  |        28  |

In both cases, we now only allocate powers of two while growing, which
may be beneficial to some allocators.

But in bootstrapped case (and in future Qt 7) SizeShift changes to 2,
and the bug becomes visible.

The added test-cases do not really reveal the issue, because we do
not run tests in bootstrapped builds, but at least they will help
to prevent the issues in Qt 7.

d027b0c816 Constrain QCoreApplication::requestPermission to compatible functors
The 6.5 versions of the overload not taking a context/receiver object
were constrained by requiring a functor to be free function or lambda.
207aae5560 removed that constraint, which
might be source incomaptible if wrapper functions in user code forward
the constraint using Expression SFINAE. Those wrappers would no longer
be removed from the overload set based on the same criteria as the
function they wrap.

We can't constrain the new functions based on the same predicate as
before, as after the simplification we have only one overload with, and
one without context object. But we can still remove overloads for
incompatible functors.

Add the respective scenario to the QPermission test as a compile-time
test.

Found during 6.6 header review.

4f4a8e75ab QItemSelectionModelPrivate: use QObjectPrivate::connect
QItemSelectionModelPrivate::initModel() uses string based connections,
to connect/disconnet its QAbstractItemModel.
The QObject::destroyed signal is connected to modelDestroyed(), which
does not disconnect other signals.

QQuickTableView's selection model binds to its QAbstractItemModel.
The binding also reacts to QObject::destroyed
Eventually, QItemSelectionModel::setModel(nullptr) is called.
At this point, only a QOBject is left from the QAbstractItemModel.
That leads to warnings about disconnecting string based signals, which
belong to QAbstractItemModel.

This patch changes the connect syntax to the QObjectPrivate::connect
API. Instead of keeping a list of string based connections around, the
connections themselves are kept in a list member. Disconnecting happens
based on that list.
Connections are also disconnected in
QAbstractItemModelPrivate::modelDestroyed.

An auto test is added in tst_QItemSelectionModel.

4ba7a76985 Allow QObjects to opt in to receiving ParentAboutToChange/ParentChange
QWidget already handles this, but it might be useful for non-Widget
object hierarchies as well, such as in Qt Quick.

The flag is opt in, and as QWidget already handles these events by
itself (without checking any flags), we assert that we don't end up
in this code path, instead of enabling it for QWidget. The latter
would mean refactoring the QWidget code, with possible regressions.

Docs and header comments have been updated to reflect that this
event is not widget specific. (This is an issue with other events
as well, that are documented to say "widget", since they came
from a time when there was only QWidget, but nowadays apply to
e.g. QWindow as well. That's something for another fix though).

7ca82250e0 tst_QFile: update virtualFile() to check if readLine() reads all
We know that all lines from /proc/<PID>/maps end in a newline, so we
trim exactly that one byte, then we put it all back together with
.join('\n') to check if we've read the entire file.

Linux virtual files are usually served in 4 kB increments; tst_qfile's
maps file is about 16000 bytes for me, just short of the QIODevice buffer:

[pid 414315] read(5, "55c6afe04000-55c6afe11000 r--p 0"..., 16384) = 4049
[pid 414315] read(5, "7f215fd25000-7f215fd26000 r--p 0"..., 12335) = 4038
[pid 414315] read(5, "7f2160800000-7f21608c7000 r--p 0"..., 8297) = 4072
[pid 414315] read(5, "7f216119f000-7f21611a0000 rw-p 0"..., 4225) = 3994

It is not a coincidence that the reads are at line boundaries, though
it's not a guarantee from the kernel.

We appear to have accidentally fixed the QEMU emulation bug by reading
another process' /proc/<PID>/maps (hypothesis: QMU emulates the target
system in /proc/self, hiding itself in maps, but makes no translation
for other process map files.

a7d2855b3c invokeMethod: enable passing parameters to overload taking functors
This was missing for a while, and there is nothing fundamentally
missing for it to work.

With the more recent work around slot objects and invokeMethod in
general, it is a good time to add support for this.

In this patch, when connecting to a functor, it automatically deduces
the overload to call based on the arguments passed to invokeMethod.

Sharing code with QObject::connect could be done, but they have a
key difference that makes it harder:
With signal emissions we throw away trailing arguments that are not
used: i.e. `signal(int, int)` can be connected to `slot(int)` or
`slot()`. With invokeMethod that's not a thing. So we will need a way
to toggle that behavior during resolution.

[ChangeLog][QtCore][QMetaObject] Added support for passing parameters
to the overload of QMetaObject::invokeMethod that takes a functor. These
new overloads must have the return-value passed through qReturnArg().

4368179c37 QTimer: fix regression on singleShot-invoking non-mormalized SLOT()s
The was introduced with the rewrite of QMetaObject::invokeMethod() in
commit 0f76e55bc4, because we have an
optimization for zero timers to avoid creating a temporary
QSingleShotTimer object. The old implementation did attempt to normalize
the target slot name, but did so because it looked metamethods up using
QMetaObject::indexOfMethod:

    int idx = meta->indexOfMethod(sig.constData());
    if (idx < 0) {
        QByteArray norm =
QMetaObject::normalizedSignature(sig.constData());
        idx = meta->indexOfMethod(norm.constData());
    }

The new implementation does not use this method so it didn't need to
attempt to normalize.

I am fixing this only in QTimer and not in QMetaObject::invokeMethodImpl
(even though it is trivial to do so) because I don't believe spaces in a
pure string to invokeMethod were ever expected to work:

    QMetaObject::invokeMethod(obj, "slotName ", Qt::QueuedConnection);

The Q_ARG and Q_RETURN_ARG (for code not recompiled) still does
normalization inside QMetaType::fromName().

4660a230d5 QString/QByteArray: fix append() wrt. raw data
When appending to an empty string or byte array, we optimize and
copy the internal pointer. But if the other string/byte array was
created with fromRawData this might be temporary data on the stack/heap
and might be de-allocated or overwritten before the string/byte array
is used or is forced to make a deep-copy. This would lead to incorrect
data being used.

This is easy to overlook if you plan to append multiple strings
together, potentially supplied through an argument. Upon appending a
second string it would make a full copy, but there might not be a
guarantee for that. So, it's hard for users to avoid this pitfall!

ccd8a496cf QXmlStreamReader::readNextStartElement() - return false on document end
The method reads the next element in a loop, as long as valid elements
exist. Within the loop, it returns
- false if the end of an element has been reached
- true if a new element has started

When the document end has been reached, the loop continues, until
readNext() returns Invalid. Then, PrematureEndOfDocumentError is launched.

This is wrong, because reading beyond the document end is caused by a
missing return condition in the loop.

=> Treat document end like element end and return false without
reading beyond it.

=> Test correct behavior in tst_QXmlStream::readNextStartElement()

9c1d20337a Remove QUuid(quint128) constructor again
This constructor matches way too many argument types (integral,
unscoped enums, FP types), so it's likely to cause mayhem, even if
left in as an explicit constructor.

We now have a named constructor for the same functionality, so just
drop the "unnamed" constructor.

"Unnamed" constructors are important when emplacement is more
efficient than construction + move, or when implicit conversion is
required.  Neither is the case here: The named as well as the
"unnamed" constructors just copy ten bytes around, and the compiler
can optimize those extra copies away just fine.

Found in API review.

f2f8820073 tests: port assorted trivial uses of Q_FOREACH to ranged for loops
All of these fall into the trivial category: loops over (readily made)
const local containers. As such, they cannot possibly depend on the
safety copy that Q_FOREACH performs, so are safe to port as-is to
ranged for loops.

There may be more where these came from, but these were the ones that
stood out as immediately obvious when scanning the 100s of uses in
qtbase, so I preferred to directly fix them over white-listing their
files with QT_NO_FOREACH (which still may be necessary for some files,
as this patch may not port all uses in that file).

1ae24f8b50 Use CLDR's names in QLocale::*ToName() for language, script, territory
Various comments need to continue using the enumdata.py names, as they
associate data with particular enum members, but we can now correctly
use the en.xml versions of their names when we report them, rather
than the enum-friendly names we use in the code. Since this now means
the data may stray outside plain ASCII - it'll be UTF-8-encoded - this
implies replacing the QLatin1StringView()s of the code that formerly
read this data with QString::fromUtf8().

d105c67a72 tst_QLocale: Use UTF-8 rather than Latin-1 for C-string-ification
Test names and output need to be UTF-8 for the XML data formats to not
end up malformed - which would upset Coin's testrunner, when it
validates the XML as part of checking - and the few other uses of
toLatin1() were to ASCII content anyway, so can harmlessly (this being
test code, where the slight performance advantage of Latin-1 doesn't
matter) use toUtf8() as well, for the sake of uniformity.

Use of toLatin1() broke an imminent commit in which some territory,
script and language names depart from ASCII, leading to malformed
UTF-8 when they appear in test-data-row names.

d1da83002d QByteArray: remove a unittest

It also had undefined behavior, when the char array used with
fromRawData() went out of, the nested, scope, the code was pointing to a
dangling stack pointer.

Thanks to Thiago for the explanation in code review.

This ties in with further changes in this series, where append() is
changed to preserve null-ness; there is no way to preserve null-ness in
append() while keeping this unittest passing.

eb0abd9789 Use QT_SUPPORTS_INT128 macro to handle 128-bit integral types
Introduce QT_SUPPORTS_INT128 and QT_NO_INT128 marcos to handle 128-bit
types. These macros allow to undef Qt's own 128-bit types and the
related code, but keep the compiler definitions unchanged.

This is required for Qt Bluetooth, where we need to use
QT_BLUETOOTH_REMOVED_SINCE to get rid of the APIs using
QtBluetooth-specific struct quint128 which clashes with the 128-bit
types. The idea is to use QT_NO_INT128 in Qt Bluetooth's
removed_api.cpp instead of directly undef'ing __SIZEOF_INT128__,
because the latter is UB.

This commit amends befda1acca.

2e9d33e534 Use correct index for QLocale::system()'s static
Nothing prevents client code from calling QLocale::setDefault() before
we ever instantiate QLocale::system() - aside from some quirks that
mean setDefault(), currently, does instantiate QLocale::system() to
force initialization of defaultLocalePrivate - so using defaultIndex()
could set the system QLocalePrivate instance's index incorrectly.

In any case, even if the index is initially set correctly, a
subsequent change to the system locale would change the correct index;
and nothing outside QLocale::system() has access to the instance that
would then be remembering an out-of-date index.

Actually tripping over that inconsistency took some deviousness, but
was possible. The index is (currently) only used for month name
lookups and those special-case, for the Roman-derived calendars, the
system locale, to only use the index if the system locale offers no
name for a month. Meanwhile, updateSystemPrivate() uses the fallback
locale's index for its look-up of which CLDR data to copy into the
fallback QLocaleData for the system locale.

None the less, a non-Roman calendar's lookup will go via the index to
get at the CLDR data for that calendar, thereby exposing the system
locale's index to use; and, sure enough, a setDefault() could lead
that to produce wrong answers.

In QLocale::system() there's a cached QLocalePrivate, whose index we
need to ensure stays in sync with the active system locale. So pass
its &m_index to systemData(), which will now (when passed this) ensure
it's up to date. Since we always have called systemData(), to ensure
it is up to date, we can skip that update in the initialization of the
cached private and use m_index = -1 to let systemData() know when it's
in the initial call, thereby making the static cache constinit.

Amended a test to what proved the issue was present.
