The comparison between nullptr and QWeakPointer was just bogus
and ill-formed. The INTEGRITY compiler catches that even if
nothing tries to use the comparison. It is an ill-formed, no
diagnostic required case of a function template never being
able to produce a valid specialization. And while we're at
it, this patch makes the result of comparing a nullptr to
a QWeakPointer or vice versa the same as asking .isNull() from
the weak pointer, because it seems mind-boggling if those
are not the same operation.

This is one of the more complicated ports. The target object
was represented by two variables in the past: A raw pointer and a
QPointer. The QPointer is checked in some cases to check whether
the target object still exists.
This patch introduces a targetObjectDestroyed() slot and connects
it to the destroyed(QObject*) signal of the target object.
In this slot, the animation is stopped. The checks become
obsolete thereby and it is sufficient to represent the target
Object in one raw pointer.
This raw pointer becomes a bindable property.

Previously, an apparent POSIX rule would be saved and any defects in
it would only be discovered when trying to use it to generate
transitions. Instead, check that it has the right form during the
initial parsing of its data.
In the process, since checking for DST in the process is trivial,
implement a long-standing TODO to cache hasDaylightTime()'s
answer. The array it scanned was in any case being scanned during
construction, so detecting DST in init()'s scan is trivial; and its
failure to check the POSIX rule mean it failed to notice when zones
entirely specified by a POSIX rule have DST.
Adapt a test using a POSIX-only rule to verify it does know the zone
has DST; it did not, before this change.

The description necessarily has fake transitions at start and end of

be reported by QTzTimeZonePrivate as transitions, although its data()
must find a "transition" whose data it can use (as in the permanent
standard time case, which could potentially be represented the same
way, although there's a saner way to do so, that the code already
handles) to report the zone's properties.
In the process, fix (and make more straightforward) the convoluted
decision-making code that was deciding which transitions to include in
the returned list. It was assuming invalidMSecs() would be set as the
atMSecsSinceEpoch of a transition, although this is computed in a way
that makes that value most unlikely, even when the result is invalid.
It also rather confusingly mixed < 0 tests as tests for overflow with
the one < 0 test that's about ignoring DST before 1970. Also added

Qt defines some integral datatypes (qsizetype, qintptr, quintptr,
qptrdiff) not in terms of the corresponding language datatypes (resp.
make_signed_t<size_t>, intptr_t, uintptr_t, ptrdiff_t) but as "integer
types with the same bit size of the corresponding language type" (and of
course the corret correct signedness for the target type).
This makes the Qt datatypes not printable via printf-like formatted
output, incl. qDebug, qWarning, QString::asprintf and so on; that's
because there isn't a format modifier that would universally work
with the Qt definitions.
For instance, on a 32 bit platform, ptrdiff_t may be a typedef for long,
while qptrdiff is a typedef for _int_ instead. Both long and int would
indeed be 32 bits, but they still are different types, and this means
that the ptrdiff_t-specific 't' length modifier would be wrong for
qptrdiff:
qptrdiff p;
printf("%td", p); // WARNING: -Wformat: wanted long, got int
Similarly, not using 't' breaks on 64 bits, and so on and so forth.
There isn't a way out, short of inserting casts on every print
statement.
So, let's adopt the same solution C/C++ use for their own integer
typedefs: the PRIx macros. This allows one to always use the correct
formatting specifier without the need of a cast.
I'm not adding the macros for the qintXX datatypes, as they already
exist in the Standard Library.
[ChangeLog][QtCore][QtGlobal] A series of PRIxQTDATATYPE macros have
been added. They make it possible to print some Qt type aliases
(qsizetype, qintptr, etc.) via a formatted output facility such as
printf() or qDebug() without raising formatting warnings and without
the need of a type cast.

UAX #29 in Unicode 11 changed the EGC algorithm to its current form.

it has been working by chance for years. Luckily, MOST

This commit:
* Adds parsing of emoji-data.txt into the unicode table generator.
That is necessary to extract the Extended_Pictographic property,
which is used by the EGC algorithm.
* Regenerates the tables.
* Removes some obsoleted grapheme cluster break properties, and
adds the ones added in the meanwhile.
* Rewrites the EGC algorithm according to Unicode 13. This is
done by simplifying a lot the lookup table. Some rules (GB11,
GB12, GB13) can't be done by the table alone so some hand-rolled
code is necessary in that case.
* Thanks to these fixes, the complete upstream GraphemeBreakTest
now passes. Remove the "edited" version that ignored some rows
(because they were failing).

This does not diminish other benefits of the new property system, which
include

- faster execution compared to QML's existing bindings and the ability

With C++20, there is a new iterator_category: contiguous_iterator, for
containers whose elements are stored contiguously in memory. In Qt 6,
QList satisfies this requirement.
However, we still need to tell the standard machinery about it. Step one
is to mark the iterators as contiguous_iterator; as that exists only in
C++20, we have to ifdef accordingly.
We also have to ensure that the iterators satisfy pointer_traits by
defining element_type due to how contiguous_range is specified. As this
runs afoul of LWG 3346, we check for known bad _GLIBCXX_RELEASE
versions.

This function returns the metatype corresponding to the metaobject, or
an invalid metatype for namespaces.
This works as follows: First we increment the metaobject revision for
new metaobjects. Metaobjects with older revisions are handled by doing a
lookup by name. That fallback is also used for dynamic metaobjects (from
QtDBUS and those created by QMetaObjectBuilder).
For new metaobjects, we store the metatype in its metatype array, behind
the property metatypes. This avoids any changes to the property and
method metatype extraction logic: For properties, the metatype access
does not change, as the new metatype is after their metatypes. For
method metatypes, we already have an indirection layer (using offsets),
so by adjusting those offsets by one, the same logic keeps working.
To distinguish between namespaces and dynamic metaobjects, namespaces
store the metatypeinterface pointer for void in the metatype array,
whereas dynamic metaobjects store a nullptr.
One nice additional benefit is that this simplifies the generator logic
in moc, as the metatype array is now never empty.

There may be a race where e.g. thread 'B' is woken up by a queued invoke.
At the same time thread 'A' asks 'B' to quit, which will set various
atomics (some important ones are 'interrupt' in the dispatcher and
'exit' in the event loop), but it does _not_ try to send another wake
since there is already an unhandled wake triggered by 'B' itself.
Sadly 'B' reads the 'exit' atomic before 'A' updates it.
Then, slightly before, 'B' sets 'interrupt' back to 0, 'A' write 1 to
it, meaning 'A's interrupt is ignored. Then, since there is no
interrupt, 'B' goes back to waiting for events, leaving the thread alive
and running instead of quitting.
Maybe this has unforeseen consequences (one consequence is that it will
return and re-enter the event dispatcher once more, possible
unnecessarily)

For now this only adds support for parsing a planned future form: the
old form using GMT is retained, to give client code some chance to
prepare for a backwards-compatible transition. Although the GMT prefix
is matched case-insensitively, only match UTC if fully upper-case;
there is no meaningful precedent for case-insensitive usage here.

UTC-based suffixes in place of the present GMT-based suffixes (which
conflict with GMT-based IANA zone names) for Qt::LocalTime and

The test verified that a LocalTime's time since Epoch changes when the
system time-zone changes. This works when the QDateTime object is in
short form and recomputes its offset from UTC every time it is needed,
but fails with a pimpled QDateTime, as this caches its offset from UTC
when it is created, saving the recomputation which - in the far more
usual case where the system time-zone does not change in the lifetime
of a QDateTime object - would normally produce the same result.
Changed the test to use a newly-created QDateTime constructed with the
same parameters, which doesn't have the cached out-of-date knowledge
of its zone offset. Removed the XFAIL. Made the test data-driven and
added test-cases: one so close to the Epoch that it should be short
even on 32-bit systems, one so far that it's pimpled even on 64-bit
systems (used in reproducing the issue in order to debug it).
This then revealed that Android 5 doesn't seem to support the POSIX
zone IDs used by this test, so it now verifies that LocalTime has the
expected offset from UTC after zone changes, QSKIP()ping if not.

The system locale of a macOS application is not affected by environment
variables like LANG. Yet, we were reporting a name determined from
environment variables as the fallbackUiLocale(), rather than one based
on the language and country of the actual system locale.
This lead, via the usual CLDR likely-subtag fallback, to claiming the
system locale's name, language, script and country were those obtained
from these environment variables, even when they were at odds with the
actual locale being used by the system, which was being used for some
queries.
Worse yet, any data not supplied by these queries was being obtained
from the same CLDR locale as the name, making for an inconsistent mix
of locale data.
While we cannot avoid the likely-subtag fallback step for fallback
data, it is more consistent to use the actual system locale's name
as start-point for that fallback.
At the same time, add support for the language, script and country
queries, so that the QLocale::system() describes itself faithfully,
instead of claiming to be the locale that results from that fallback.
If we want to support LANG or other environment variable overrides,
they should be handled by the layer above the system locale, by
changing the default locale of the Qt application, as if the user
had called QLocale::setDefault().
[ChangeLog][QtCore][QLocale] QLocale::system() on macOS no longer
pretends to support LANG or other environment variables as overrides,
as this is not a feature that the system locale on macOS supports.
To override the locale of an application, use QLocale::setDefault(),
or pass -AppleLocale en_US.

To optimize certain operations, it can be useful to know whether we are
currently evaluating a binding. For instance, we have properties whose
storage is only alloctaed on-demand when they are set. However, we would
also allocate them if they are used in a binding context, as we would
otherwise not properly track the dependency. Using
isAnyBindingEvaluating in the getter, we can detect this
situation, and avoid the allocation if it returns false.
This API is private for now, as it exposes some internals of the
property system and should be used with care. As it needs to access the
TLS variable, it also has a non-negligible cost.

When creating a time-zone from a UTC+offset name that isn't known to
the system, QTimeZone (since the fix to QTBUG-77738 in 5.15.0) falls
back to constructing a suitable UTC-offset backend; however, the id of
this is not guaranteed to match the id passed in to the constructor.
In all other cases, the id of a QTimeZone does match the id passed to
its constructor.
Some utcOffsetId testcases had different id() than the id passed to
the constructor, due to mismatches where a zone was constructed using
the fall-back but the generated id included its minutes (as :00) or
omitted its seconds. The omission of seconds is clearly a bug, but we
also don't want to include :00 for seconds when it's not needed. So
change QTimeZonePrivate::isoOffsetFormat() to accept a
QTimeZone::NameType to configure how much we include in an id. Its
callers other than the relevant constructor (from offset) still get
minutes, even when :00, but will also get seconds added if that isn't
zero; and the constructor from offset now gets the short form obtained
by omitting all trailing zeros.
Since all valid whole-hour offset names that do include :00 for the
minutes field are in fact known standard offset names, the elision of
minutes will only affect zones created by ID in the case of a
whole-hour offset given without :00 minutes specifier, so these shall
necessarily in fact get the ID passed to the constructor. Creating by
UTC-offset with a name that specifies zero seconds will result in a
QTimeZone instance whose id() differs from what was passed to its
constructor (eliding the :00 seconds and potentially also minutes, if
also zero) but this should be the only case where a QTimeZone's id
doesn't match the one passed to the constructor, when constructed by
id.
Fixed inconsistency between the offset-constructor's declaration
(taking offset as int) and definition (taking qint32) in the process.
Added an id check to the utcOffsetId() testcase. Amended two tests of
offset-derived time-zones' IDs, added comments to make clear how one
of those differs from a matching standard name test and converted two
uses of QCOMPARE(, true) to QVERIFY().
[ChangeLog][QtCore][QTimeZone] QTimeZone instances created by offset
from UTC (in seconds) shall now only include minutes in their ID when
the offset is not a whole number of hours. They shall also include the
seconds in their ID when the offset is not a whole number of minutes.

Fix issue on reallocateAndGraw and avoid accessing

Data::allocate can return invalid header and dataptr,
which takes place if capacity is 0. In code before 6be398
clone method checks if header is not null before resetting
flags. However after b76fbb4 resetting flags is no longer
needed since it is done in allocateGrow.

Historic QDateTime behavior when being asked to create a
QDateTime in the DST gap was to interpret the given date
as if it was in the time before that gap, mapping it to a point
in time after the gap. This has changed with
a04411119e .
Since then, the given date is interpreted as if it was in the
time after the gap, thus being mapped to a point in time
before the gap.
This patch restores the historic behavior.
This was not caught by Coin because machines ran in timezone
"Atlantic/Reykjavik" which does not have DST since 1967.
This patch changes tests to always run in "Europe/Oslo".
Driveby: Test function "findSpring" did some operations in
local time, even though being asked to work in a specific
time zone. Fixed that.

Technically, having a single constructor limits the use-cases for this
class. We should take into account that:
- an opened socket descriptor must be available at the moment of
construction;
- the constructor unconditionally enables the notifier (the possible
solution
notifier = new QSocketNotifier(...);
notifier->setEnabled(false);
is suboptimal due to heavy operations inside the event dispatcher);
- for these reasons, QSocketNotifier most often cannot be a member of
another class (we have an extra allocation and indirect access).
This patch addresses this shortcoming by making it possible to set the
socket descriptor at a later point:
[ChangeLog][QtCore][QSocketNotifier] Added setSocket() and an additional
constructor which requires no socket.

Because CBOR strings are encoded in UTF-8, it's possible that the string
that won't fit a QString in UTF-16 would still fit QByteArray in UTF-8
(e.g., anything US-ASCII and most Latin text).
The previous solution was an improvement because we used to read into a
QByteArray then convert the QByteArray to QString, thus using 3x the
amount of memory (1x in QByteArray, 2x in QString). The previous commit
skipped the middle allocation and made the regular readString() function
do the decoding either directly on source memory or by reading in small
chunks (16 kB).
Future improvement for Qt 6.1: add readStringChunk(char16_t *, qsizetype)
so we can do the validation / skipping at O(1) memory.

By calling the internal readStringChunk() function with a QByteArray
pointer, QCborStreamReader::readByteArray() can now avoid allocating the
resulting buffer until the internals have confirmed that there is
sufficient data in the incoming buffer. As a result, we first detect the
EOF condition before we conclude the payload would have been too big for
QByteArray (validation()) test. Meanwhile, the hugeDeviceValidation()
test ends up with a few conditions where it would have copied 1 GB of
data, so limit that too.
We make a choice of reporting OOM vs DataTooLarge only if QByteArray
fails to allocate in the first place (QByteArray::resize() ->
Q_CHECK_PTR -> qBadAlloc, QtCore is always built with exceptions on).
The QCborValue unit test needed a temporary work around until we apply
the same allocation fix (see next commit).
