cb39ea0581 Make the signal argument in Q_OBJECT_BINDABLE_PROPERTY optional
The intention was always that you can define properties that do
not require a changed signal. But having to explicitly pass
a nullptr as signal parameter into the macro is ugly, so
use the cool QT_OVERLOADED_MACRO to make it optional.

9a55f40937 QCborStreamReader: avoid allocating result if data is insufficient
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).

If a QBindable is created from a computed property, it is not possible

405244fe30 Fix QVariant/QMetaType::compare APIs
std::optional<int> is the wrong datatype to use for compare.

First and foremost, it can't be used in the idiomatic form of

  auto r = a.compare(b);
  if (r < 0) ~~~ // a is less than b
  if (r > 0) ~~~ // a is greater than b

which we *already* feature in Qt (QString, QByteArray).

Also, std::optional<int> (explicitly) converts to bool, which is
a trap, because the result of the comparison can be accidentally
tested as a bool:

  if (a.compare(b)) ~~~ // oops! does NOT mean a<b

Not to mention extending this to algorithms:

  auto lessThan = [](QVariant a, QVariant b) { return a.compare(b); }; // oops!
  std::ranges::sort(vectorOfVariants, lessThan);

which thankfully doesn't compile as is -- std::optional has
an *explicit* operator bool, and the Compare concept requires an
implicit conversion. However, the error the user is going to face
will be "cannot convert to bool because the operator is explicit",
which is deceiving because the fix is NOT supposed to be:

  auto lessThan = [](QVariant a, QVariant b) { return (bool)a.compare(b); }; // big oops!

Instead: backport to Qt the required subset of C++20's <compare>
API, and use that. This commits just adds the necessary parts
for compare() (i.e. partial ordering), the rest of <compare>
(classes, functions, conversions) can be added to 6.1.

81e893fb2d QHash: support std::hash as hashing function
In addition (and as a fallback) from requiring qHash, add support
for std::hash specializations. This catches two birds with one stone:

1) users of Qt can simply specialize std::hash for their datatypes,
and use them in both QHash and stdlib unordered associative containers;

2) we get QHash support for any (stdlib) datatype that is hashable
without having to overload qHash for them.

[ChangeLog][QtCore][QHash] QHash, QMultiHash and QSet now support
for key types anything that can be hashed via std::hash, instead of
always requiring a qHash() overload.

Q_MOVABLE_TYPE was conceived before C++ had move semantics. Now, with

introduced as a synonym to Q_MOVABLE_TYPE. Usage of Q_MOVABLE_TYPE
is discouraged now. This patch replaces all usages of Q_MOVABLE_TYPE
by Q_RELOCATABLE_TYPE in QtBase. As the two are synonymous, this

b4c1747612 Make QMetaTypeInterface constexpr on Windows
This was so far problematic as it gave various link errors. The solution
to that seems to be to make the default constructor of QPairVariantInterfaceImpl
constexpr to get around one set of problems.

The other problem to solve where undefined references to metaobjects. The
reason for that is apparently that QMetaTypeInterface contains a direct
pointer to the meta object, something the linker doesn't like. Adding a
level of indirection by using a function that returns the pointer seems
to solve that problem.

- If maximum is smaller than minimum, minimum becomes the only legal
value.
- If the current progress value falls outside the new range, the
progress value is set to be minimum.
- If both progressMinimum() and progressMaximum() return 0, the

value can be set.
- When setting the value using setProgressValue(), if the value falls
out of the progress range, the method has no effect.

168772fe8f Remove destructor calls from insert()
QList::insert() should never need to call a destructor. This
requires that we construct the new items in the list in order
and increment the size each time we constructed a new item.

Not having a code path that potentially calls destructors should
avoid the generation of lots of additional code for those
operations. In addition, the forward and backwards code paths
are now unified and only require somewhat different setup of
some variables at the start.

This gives us strong exception safety when appending one item,
weak exception safety in all other cases (in line with std::vector).

621c05e3b1 Don't allow storing types that throw in the destructor in our containers
Types that throw in their destructors are strongly discouraged in C++,
and even the STL doesn't define what happens if such types are stored
in their containers.

Make this more explicit for Qt and disallow storing those types in our
containers. This will hopefully preempty any potential future bug
reports about us not handling such a case. It also helps simplify
some code in QList and other cases and makes it possible to explicitly
mark more methods as noexcept.

Some care needs to be taken where to add the static asserts, so that
we don't disallow forward declarations of types stored in containers.
Place the static assert into the destructor of the container where
possible or otherwise into the templated d-pointer.

Construction of QFileInfo from QString (or similar) should be not
implicit, as QFileInfo construction is expensive (might hit the file

QFileInfo out of QDirIterator::next(), instead of using ::fileInfo();
using QDir::entryList instead of entryInfoList; etc.).

Leave an opt-out mechanism to ease porting.

likely to be actual "sloppy" code.

1869615fc9 QChar: make construction from integral explicit
QChar should not be convertible from any integral type except from
char16_t, short and possibly char (since it's a direct superset).

David provided the perfect example:

  if (str == 123) { ~~~ }

compiles, with 123 implicitly converted to QChar (str == "123"
was meant instead). But similarly one can construct other
scenarios where QString(123) gets accidentally used (instead of
QString::number(123)), like QString s; s += 123;.

Add a macro to revert to the implicit constructors, for backwards
compatibility.

The breaks are mostly in tests that "abuse" of integers (arithmetic,
etc.). Maybe it's time for user-defined literals for QChar/QString,
but that is left for another commit.

[ChangeLog][Potentially Source-Incompatible Changes][QChar] QChar
constructors from integral types are now by default explicit.
It is recommended to use explicit conversions, QLatin1Char,
QChar::fromUcs4 instead of implicit conversions. The old behavior
can be restored by defining the QT_IMPLICIT_QCHAR_CONSTRUCTION
macro.

039d3fe4e8 Android: blacklist a list of failing tests for android
We want to re-enable Android tests in QTQAINFRA-3867. However,
many tests are failing already preventing that from happening.
QTBUG-87025 is currently keeping track (links) to all of those

Android test running in COIN for other tests. After, that try
to fix them one by one, and at the same time we can make sure

8f7016252a Implement QList::emplaceBack as a proper function
My endeavours figuring out why QList::append(elem) gives worst
performance compared to 5.15 ended up into this commit. After some
straightforward fixes, what was left is "everything is uniformly worse"
and takes more CPU cycles

Introduce emplaceBack implementation as append is quite a special case
that could be greatly simplified. This is a "straightforward" part of
the optimizations

While at it, change append(t) to use emplaceBack(t)

For workloads like:
QList<int> list;
forever {
  list.append(0);
}
this gives huge improvement (roughly 30% for 10k+ elements),
movable and complex types also get a tiny speedup

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

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.

implicitly in tst_qdate / tst_qdatetime / tst_qdatetimeedit etc.
This made it difficult to test some corner cases, especially in the
context of unfinished dates, i.e. dates which are invalid, but could
become valid by adding more characters. This is used to validate
user input in qdatetimeedit.

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.

These classes should not inherit from each other

This way, QMutex can now inline the fast path

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.

Add some test cases to verify the mappings.

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.

97de53ee8c QUrl::fromLocalFile: accept invalid hostnames
QUrl hostnames must be compliant with STD3, but we must somehow accept
file paths that begin with double slash but aren't valid hostnames.
Because the file URI spec requires us to start with "file://" anyway, we
can represent those with four slashes. Note that on Unix "//X/y" is a
valid but local file path. If given to QUrl::fromLocalFile(), if the
path at the root does parse as a hostname, we will still try to
normalize (the above becomes "file://x/y").

[ChangeLog][QtCore][QUrl] Changed QUrl::fromLocalFile() to accept
Windows UNC paths whose hostname component is not a valid Internet
hostname. This makes QUrl able to accept extended-length paths (\\?\),
device namespace (\\.\),  WSL (\\wsl$), etc.

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
now reject trailing cruft (including spaces) at the end of a time
string. They also gain support for parsing hour-only formats,
including the hour-with-fractional-part format.

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.
