When some test function fails (even as expected), it can leave the
event dispatcher in an inconsistent state where the posted events
queue might not be empty. As a result, this may break the internal
logic of the next test function that is run.
So, calling eventDispatcher->processEvents() after each completed
function resets the event dispatcher to its initial state, which
fixes the problem.

We set the wakeUps atomic to prevent multiple WM_QT_SENDPOSTEDEVENTS from
being posted. However, this might happen right after the event processing
thread cleared the atomic, but before it processed the previous
WM_QT_SENDPOSTEDEVENTS message. In that case, we end up with a set
atomic and an empty event queue, resulting in the event loop to block
even though there are posted QEvents.
To prevent that, always reset the atomic when we handle the
WM_QT_SENDPOSTEDEVENTS message. In that case, we either call
sendPostedEvents, or startPostedEventsTimer. The former already resets
wakeUps; reset it in the latter as well.

Add two tests for some problematic scenarios where the behavior is not
consistent across platforms and depending on which event dispatcher is
used:
1) reliably waking up the dispatcher when posting events from a worker
thread.
That test fails 100% of the time on Windows no matter what type of
application is created. It passes reliably on Linux and macOS for both
core and gui applications.
2) waking up the dispatcher when we post an event from within an
event handler.
That test fails 100% of the time on Windows, both with core
and GUI event dispatchers. On macOS, the test fails 100% of the time
with the core dispatcher, and passes 100% of the time with the GUI
dispatcher. On Linux, it passes only if a Glib based event dispatcher
is used; the default Unix event dispatcher (which is also the one
used on macOS for core applications) fails.

fundamental relation
size() - capacity() == freeSpaceAtEnd()
which, however, Qt 6's prepend()-optimization (freeSpaceAtBegin())
broke. Because of that, while size() - capacity() may be large enough
to hold the new data, if freeSpaceAtBegin() > 0, then freeSpaceAtEnd()
may not.
Fix by inspecting freeSpaceAtEnd() instead of capacity(). The
following reserve() call is unaffected, since it internally already
adds freeSpaceAtBegin() to the requested size, which is why the

Due to the way Qt 5 and 6 registered type names, they end up producing
different type names for the same content for a typedef. For example,
because Q_DECLARE_METATYPE can't manage a comma (it's a macro), users
are forced to write something like:
using MyTypeMap = QMap<QString, MyType>
Q_DECLARE_METATYPE(MyTypeMap)
Qt 5's Q_DECLARE_METATYPE's argument "MyTypeMap" was the only name we
knew about the type, so that's what got saved in the stream. However, Qt
6 QtPrivate::typenameHelper is much more clever and obtains the name
from the compiler itself, so it "sees through" the typedef and registers
"QMap<QString,MyType>" as the official type name.
If another library/plugin has a different typedef name for the same type
(e.g., StringTypeMap), it's indeterminate which type gets saved and will
even change from run to run (depends on the QHash order).

The old code had several bugs:
- it immediately clobbered *this with new state, before having copied
over the elements from the old to the new buffer
- when buffer relocation threw, it would keep the new (partially-filled)
buffer and throw away the old
- it unconditionally used std::move() for non-relocatable types, making
it impossible to restore the original buffer when a move throws
Instead of clobbering *this with new state, do all the work on the
side and change *this only once the reallocation has happened
successfully.
Also use q_uninitialized_relocate_n() and unique_ptr in the
implementation to simplify the code. The former got the necessary
update to use std::move_if_noexcept() instead of an unconditional
std::move() for the non-relocatable case.
[ChangeLog][QtCore][QVarLengthArray] The append()-like functions are
now strongly exception safe. This means reallocation will now use
copies instead of moves, unless the value_type has a noexcept move

If one destroys a running QThread, so far the behavior has been to crash
(à la std::thread) -- assuming the thread hasn't already signalled that
it has finished. This behavior is hostile to solutions such as using
QThread::create(), which always require a wait() before destroying the
thread object.
We can use the opportunity to change the behavior without breaking any
valid code. Instead of crashing, inside QThread's destructor we can ask
the new thread to quit, and then join it (à la std::jthread). This
simplifies the implementation of long-living runnables and the code that
manages them.
Deploying this solution for the whole QThread class may not be entirely
painless. While no correct code would work differently with the proposed
changes, incorrect code that deletes a running thread would no longer
crash "loudly" -- instead, it might deadlock "quietly", have memory
corruptions, etc.
Hence I'm limiting this approach to only the threads created by
QThread::create(), at least for the time being. This also side-steps
perhaps the biggest problem of generalizing the approach, which is that
placing such interrupt+join logic into~QThread's destructor would cause
it to be run _after_ a QThread subclass' own destructor has run,
destroying the subclass' data members too early. This might create
an antipattern if one chooses to subclass QThread. With create(), a
subclass in question exists, and it indeed has NSDMs, but it's entirely
under our control (in fact, I'm placing the logic just in its dtor).
[ChangeLog][QtCore][QThread] Destroying a QThread object created by
QThread::create() while the thread that it manages is still running will
now automatically ask that thread to quit, and will wait until the

The only documented replacements for Q*String*::arg() are sequences like
%1, %2, %3 -- where the n-th number is expressed using a sequence of
ASCII digits [1].
The code parsing the replacements however used the QChar::digitValue()
function. That function simply checks if a QChar has a *Unicode digit
value* (no matter what its block/category is), and if so, returns the
corresponding digit value as an int (otherwise returns -1).
The result of this is that a sequence like "%¹" or "%१" actually
triggered substitutions (both count as "1"). Similarly, QChars with
a digit value would be parsed as part of longer sequences like "%1²"
(counting as "12" (!)).
This behavior is weird, undocumented, and extremely likely the usual
backstabbing by Unicode by using "convenience" QChar methods -- that is,
never *intended* by the implementation.
This commit deprecates (via warnings) such usages, which for the time
being are left working as before (in the name of backwards
compatibility). At the same time: given it's extremely unlikely that
someone would be deliberately relying on this behavior, it implements
the desired change of behavior (only accept sequences of ASCII digits)
starting from Qt 6.6, that is, after the next LTS.
Throughout Qt 6's lifetime users will still be able to control arg()'s
behavior by setting an env variable, but that variable (and the support
for Unicode digits) will disappear in Qt 7.
To summarize:
* Qt 6.3->6.5: default is Unicode digits, env var to control
* Qt 6.6->6.x: default is ASCII digits, env var to control
* Qt 7: only ASCII digits, no env var
[1] That's the name Unicode gives to them, cf. https://www.unicode.org/charts/PDF/U0000.pdf
[ChangeLog][QtCore][Deprecation Notices] The arg() functions
featured in Qt string classes have always been documented to require
replacements tokens to be sequences of ASCII digits (like %1, %2, %34,
and so on). A coding oversight made it accept sequences of arbitrary
characters with a Unicode digit value instead. For instance, "%2੩" is
interpreted as the 23rd substitution; and "%1²" is interpreted as the
12th substitution. This behavior is deprecated, and will result in
runtime warnings. Starting from Qt 6.6, arg()'s behavior will be changed
to accept only ASCII digits by default. That means that "%1²" is going
to be interpreted as substitution number 1 followed by the "²" character
(which does not get substituted, so it gets left as-is in the result).
Users can restore the previous semantics (accept Unicode digits) by
setting the QT_USE_UNICODE_DIGIT_VALUES_IN_STRING_ARG environment
variable to a non-zero value. In Qt 7, arg() will only support sequences
of ASCII digits. Note that from Qt 6.3 users can also set
QT_USE_UNICODE_DIGIT_VALUES_IN_STRING_ARG to zero; this will make arg()
use ASCII digits only, in preparation for the future change of defaults.

Q(Multi)Map mutating functions that take reference to a key and/or a
value (e.g. insert(), take(), etc.) must make sure that those references
are still valid -- that is, that the referred objects are still alive --
after the detach() call done inside those functions.
In fact, if the key/value are references into *this, one must take extra
steps in order to preserve them across the detach().
Consider the scenario where one has two shallow copies of QMap, each
accessed by a different thread, and each thread calls a mutating
function on its copy, using a reference into the map (e.g.
map.take(map.firstKey())). Let's call the shared payload of this QMap
SP, with its refcount of 2; it's important to note that the argument
(call it A) passed to the mutating function belongs to SP.
Each thread may then find the reference count to be different than 1 and
therefore do a detach() from inside the mutating function. Then this
could happen:
Thread 1: Thread 2:
detach() detach()
SP refcount != 1 => true SP refcount != 1 => true
deep copy from SP deep copy from SP
ref() the new copy ref() the new copy
SP.deref() => 1 => don't dealloc SP
set the new copy as payload
SP.deref() => 0 => dealloc SP
set the new copy as payload
use A to access the new copy use A to access the new copy
The order of ref()/deref() SP and the new copy in each thread doesn't
really matter here. What really matters is that SP has been destroyed
and that means A is a danging reference.
Fix this by keeping SP alive in the mutating functions before doing a
detach(). This can simply be realized by taking a local copy of the map
from within such functions.
remove() doesn't suffer from this because its implementation doesn't do
a bare detach() but something slightly smarter.

QObjects must be deleted if the QCoreApplication is being destroyed.
This was previously done by implementing custom code in qtbase and

The relevant MS system calls (say they) don't support date formatting
for years < 1601 (but apparently do in fact) and the year field of the
data structure is unsigned, so can't support years < 0. As a result,
the windows back-end for QSystemLocale failed for negative years.
So replace year < 1601 with a place-holder and substitute after
formatting.
Added new tests (based loosely on one in qtdeclarative that failed) to
verify that this actually works. These reveal that macOS also fails to
handle negative years; marked as expected failure there pending a fix.

The documentation for QProcessEnvironment's default constructor
says:
This constructor creates an empty environment. If set on a
QProcess, this will cause the current environment variables
to be removed.
This is not the case however, because setting such an environment
for a process is equivalent to not setting an environment at all
and the child process is executed with parent's environment.
It is still possible starting from Qt 6.2.0 to create an empty
environment by adding a variable to a null environment and removing
it, but that's cumbersome, and the comparison operator says that
it is equal to the null environment but it is obviously behaving in
a different way.
This change adds an additional constructor to QProcessEnvironment
that can be used to construct a null environment, and changes the
default constructor to produce an empty environment. The comparison
operator is changed to correctly distinguish between such objects.
This is a behavior change, but the current behavior is broken
and this is unlikely to affect working code.
[ChangeLog][QtCore][QProcessEnvironment] An additional constructor
was added to explicitly create an object that when set on QProcess
would cause it to inherit the environment from parent (this was
formerly the behavior of a default-constructed QProcessEnvironment,
which will now (as documented) actually give a process an environment
with no variables set). A new method inheritsFromParent() was added
to test for such objects.

When declaring metatypes, the metatype system tries to detect if the
comparison operators for the given type exist and automatically register
them. In case of QHash, the equality operator was enabled if the value
type provides one. But the implementation needs equality operator of
the key type as well. As a result, when the key type has no equality
operator, the metatype system detects that the equality operator is
available for the QHash itself, but the compilation for metatype
registration fails when trying to instantiate the code that uses
equality operator for the key. This is fixed by enabling equality
operators for the QHash only when both the key and value types provide
one.
The same issue existed also for QMultiHash, with the difference, that
QMultiHash didn't have the constraints even on the value type. So added
checks for both.
