1b8b802455 tst_QAnyStringView: explicitly check the spaceship operator
We implicitly checked it, because, in C++20 builds, the non-equality
relational operators are synthesized from it by the compiler, and we
test those, but we didn't check that <=> returns strong_ordering.

We now do.

865212057b Windows: fix DeferredDelete events processing on QThread::terminate()
On finishing/terminating a thread, when processing posted events,
we need to consider QThread's own data instead of caller thread's data.
Otherwise we can get into unexpected situations such as double

0681a2dd5a QTestLib: rework QTest::compare_helper()
[ChangeLog][QTestLib] QCOMPARE now evaluates toString() on its
arguments lazily, speeding up the general case where the comparison
doesn't fail. This is true for the QCOMPARE functionality provided
by Qt. If you specialized qCompare() for your own types, then you
need to change its implementation in line with Qt's own qCompare()
specializations in order to enable this feature.

[ChangeLog][QTestLib] QCOMPARE calls with nullptr argument(s) will
now print the actual and expected values upon failure.

Previously it was not like that because of the compareHelper()
overload in qtestresult.cpp that treated the presence of
nullptr-arguments as a reason to ignore formatFailMessage() call.
New implementation does not have this check, and correctly
executes formatFailMessage() for all arguments.

Note that the qCompare() overloads that call QTestResult::compare()
internally were not affected by this patch, because they already
defer toString() invocation until the comparison fails.

Some numbers, collected against shared release developer build.
I checked how this change affects the test execution. The idea was
to pick some tests for types that do not have a specific
QTestResult::compare overload, so I picked a couple of QByteArray
tests.
The comparison is done by running a test 10 times and taking the
average execution duration, as reported in the log.

tst_qbytearrayapisymmetry:
 Before: 15.6 ms
 After:  14.2 ms

tst_qbytearray:
 Before: 41 ms
 After:  36 ms

The benefit is around 9% and 12% respectively.

1e36eedb7f tst_QStringApiSymmetry: use QCOMPARE_EQ instead of QCOMPARE
This allows to defer the toString() invocation until it is really
needed, and so allows to speed-up the test execution.

I was testing a release shared developer build, running
tst_QStringApiSymmetry 10 times before the change, and 10 times after
the change, and then taking the average execution duration, as
reported in the log.

Before the change (using QCOMPARE): 51ms
After the change (using QCOMPARE_EQ): 45ms

As we see from the results, the benefit is around 10%.

3dcf1779be tst_QUrlQuery: improve formatting of lists of pairs of strings
The compare() implementation made its actual and expected seem to have
different types (using a typedef name for one, when the other was of
the type that expands to) and the formatter it used was needlessly
clunky. Use modern string literals and package a repeated
null-or-quoted representation as a lambda, inline the resulting
simplified prettyElement() into prettyPair(), which can now just take
a pair rather than an iterator. Short-cut the empty list so that the
comma-joined accumulation could initialize with the first entry and
loop over the rest, always joining with a comma.

Undo commit f776595cc10aaafc7162f382a8fa11afffb0e708's mistaken update
to the copyright header and update correctly.

This is an implementation of function_ref, which has been proposed for
inclusion into C++23, but has not been accepted, yet, which is why we
place it in namespace qxp (for eXPerimental) instead of q23.

The implementation is based on wg21.link/P0792r9, which, at the time
of writing, is the latest revision of the paper. It will be used in
both QTestLib and qmldom.

5e48a51608 Long live QAtomicScopedValueRollback (private API)!
QScopedValueRollback has a few users that apply it on QAtomicInt,
which happens to work as QAtomicInt is copy-constructible and its
ctors are implicit.

But that's of course nonsense. We don't need to store the oldValue in
an atomic, nor do we need to pass the new value into the ctor as an
atomic.

So, add a QAtomicScopedValueRollback which works on std::atomic as
well as the Qt atomics, but distinguishes between the reference (which
is atomic) and the value (which isn't), and use it in one of the
users, tst_QList.

Keep it private until we know whether there's an actual need for this.

The test is a copy of tst_qscopedvaluefallback, so the occasional
oddity (like atomic op*=) should be ignored.

31f98957cf Add compile-time generation of JNI class names
As with method signatures, register class names using template function
specialization in the QtJniTypes namespace, and then declare C++ types
as JNI classes with a class name string. Such classes implicitly get
registered as JNI types as well.

Add a QJniObject construct method (since C++ constructors that are
templates cannot be explicitly instantiated with a type), and a
QJniEnvironment::findClass overload.

Add test coverage, also for the recently added macros for native
methods.

As a drive-by, change the name of the Q_JNI_DECLARE_NATIVE_METHOD
macro to Q_DECLARE_JNI_NATIVE_METHOD for consistency.

9bad4be214 QStringConverter: use the QUtf8 codec when Windows is using UTF-8

continuation byte -- that is, that all codecs are either Single or
Double Byte Character Sets (SBCS or DBCS). It appears to be the case for

anyway.

Instead of fixing our codec, let's just use the optimized UTF-8
implementation.

as the system codepage or by enabling that in the application's

dd8da7ebd9 Compile-time generate a JNINativeMethod from a C function
Add a template function that allows us to get the method signature
string from a free function, which are used as native callbacks methods
from Java.

Provide a macro that defines a signature object, and a JNINativeMethod
object based on it, in an internal namespace so that we don't pollute
the namespace with generated names.

Add another macro to get the generated JNINativeMethod object based on
the free function name.

Lastly, add overloads to QJniEnvironment::registerNativeMethods that
take a std::initializer_list of JNINativeMethods.

We can now declare a free function to be a JNI native method:

static bool callbackFromJava(JNIEnv *e, jobject /*thiz*/, jstring p1)
{
   // ...
}
Q_JNI_DECLARE_NATIVE_METHOD(callbackFromJava);

and register it with the JNI environment like this:

QJniEnvironment jni;
jni.registerNativeMethods(clazz, {
    Q_JNI_NATIVE_METHOD(callbackFromJava)
});

removing a significant amount of boiler plate code.

367092d7e0 Return specific types for frequently used Java objects
This allows us to specialize JNI type signature templates for e.g. the
context object, which in Java signatures is "android/content/Context".

Introduce a Q_DECLARE_JNI_TYPE macro that takes care of the plumbing.
The types declared this way live in the QtJniTypes namespace, and
transparently convert from and to jobject. Since jobject is a typedef
to _jobject* we cannot create a subclass. Use a "Object" superclass
that we can provide a QJniObject constructor for so that we don't
require the QJniObject declaration to be able to use the macro.

The APIs in the QNativeInterface namespace doesn't provide source or
binary compatibility guarantees, so we can change the return types.

601dbd6499 Add variadic template overloads for QJniObject/Environment methods
This allows the compiler to deduce the template arguments based on the
provided method parameters, which we can then pass to the methodSignature
and fieldSignature helpers to generate the signature string completely at
compile time.

Since we can't partially specialize template member functions, replace
the specializations for void methods with compile-time-if branches in
the general templates.

This variadic template now prevents implicit conversion from the
LiteralStorage types to const char* signatures, so catch the case where
such a type ends up in the parameter list.

Due to overload resolution rules for constructors, we need to explicitly
disable the constructor if any of the arguments is a string literal type,
as we have to keep the old C-style variadic function working for such
calls.

Add variations that use the variadic templates to the unit tests.

4e7f92bf0d QMetaType: Fix normalization on MSVC if name contains enum
During type normalization, we remove the struct, class and enum
keywords (see the skipStructClassOrEnum function). However, we only want
to do that for actual keywords, not for a name that happens to start
with e.g. "enum", as in "enumerationNameSpacce".
Adjust the MSVC check to still require no identifier character after the
keyword, while still allowing for some remaining characters.

20104bb237 Remove remnants of the old Intel C++ compiler
We don't support it any more. I don't think it has ever properly
compiled Qt 6 (and it's no longer working for me against GCC 12's
libstdc++ headers). If you report a bug against it, Intel support's
first question is if you can try instead the new Clang/LLVM-based oneAPI
C++ compiler.

So we support only that one, which identifies itself as Q_CC_CLANG.

38002df206 Endian: Provide special integer bitfield unions
Our previous approach of creating a union from individual special
integer bitfields leads to undefined values because only one member of a
union can be active at any given time. Compilers have finally caught up
with us on that and have started removing "no-op" writes to members.

The primary user of the special integer bitfield unions is
qv4compileddata_p.h in qtdeclarative. We want our on-disk format of
QML compilation units to be platform agnostic and space efficient.

a085a14d76 Generate JNI signature strings at compile time
Introduce an internal QtJniTypes namespace with types that allow us to
concatenate string literals at compile time. This makes it possible to
generate arbitrary strings based on types, which we can then use as
signatures to JNI method calls.

Move some of the private members of QJniObject into the QtJniTypes
namespace for consistency, and to allow further template specialization
by user code to make other types and their JNI signature string known.
Remove the "Jni" prefix from names.

Use the compile-time generated string in QJniObject methods that created
the signature string at runtime, which involved a temporary memory
allocation.

Treat 'void' as a primitive type (with signature string 'V'), and
remove redundant template specializations.

Add a test case to verify the the strings are constructed correctly
at compile time.

7905b624fd QTextStream: fix streaming of char16_t's
Clazy complains about all uses of QLatin1Char these days, but if one
actually applies the fixit to turn

   out << QLatin1Char(' ');

into

   out << u' ';

the space is now streamed as an int (20), not as a space.

Fix by providing an explicit char16_t overload.

[ChangeLog][QtCore][QTextStream] Added op<<(char16_t).

[ChangeLog][Important Behavior Changes] QTextStream streams char16_t's
as QChars now instead of outputting the numeric value. If you want to
preserve the old behavior, cast the char16_t to a numeric type, such
as ushort or int, and stream that. This is backwards-compatible.

e48b4d2b7c Implement support for '0b' prefix in toInt() etc
[ChangeLog][QtCore][QByteArray/QByteArrayView/QLatin1String/QString/QStringView]
The string-to-integer conversion functions (toInt() etc) now support
the 0b prefix for binary literals. That means that base = 0 will
recognize 0b to mean base = 2 and an explicit base = 2 argument will
make toInt() (etc) skip an optional 0b.

[ChangeLog][QtCore][Important Behavior Changes] Due to the
newly-introduced support for 0b (binary) prefixes in integer parsing,
some strings that were previously rejected as invalid now parse as
valid. E.g., Qt 6.3 with autodetected bases would have tried to parse
"0b1" as an octal value and fail, whereas 6.4 will parse it as the
binary literal and return 1.

0b5b98c4ae Fix qlocale_unix's handling of uiLanguages to take script into account
Some languages have, in the same territory, locales for more than one
script. In such cases, since we ignored the script, we got the one
that is used by default, instead of the one actually asked for. Take
the script into account.

Added TODO comment in test listing the known examples of this;
manually tested before and after the fix to verify the prior code was
indeed getting it wrong and now does do it right.

7a7f2547f3 Return more specific entries before less in QLocale::uiLanguages()
The documentation overtly listed entries in this order but the code
gave less specific entries before more specific (and the tests
verified the same). This is now reversed.

[ChangeLog][QtCore][QLocale] uiLanguages() now prefers more specific
locale names over less specific ones, matching its own documentation,
except where the system backend supplies them in some other order.
This means a translation with the expected script and/or territory as
well as language will be used in preference to a generic one for just
the language, rather than only as a fall-back when the more generic
one is missing.
