59df5dacd5 Fix QString test compilation without QRegularExpression
The QString itself can be compiled without QRegularExpression, but
the tests do not check if they are supported or not.
This patch fixes the issue by introducing the proper #ifdef guards.

8ac686e9f4 QString: extend unit tests
This patch introduces some test improvements to check the calls of
different methods on an empty default-constructed string.
Apart from that, some other tests are added to extend code coverage.

As a drive-by:
* fix int -> qsizetype in the test data
* fix int -> enum in the test data

cc64959602 Tidy up tst_QString::localeAwareCompare()
It was suppressed unconditionally (albeit in different places and with
different levels of obviousness) almost everywhere, due to inability
to set the system locale in use by the implementation. Several
test-cases used ISO-8859-1 encoding on Q_OS_MAC, where the tests were
all suppressed anyway. A block of no_NO tests was #if 0'd out; and
should, in any case, have been nb_NO. Tests of any locale but en_US
were skipped on Q_OS_WIN because we can't set the locale (but
including the tests of en_US tacitly assumed that's the system
locale). If setlocale() failed, for ICU or DARWIN, the test was
skipped; but we might as well check for this in the _data() to save
repetition.

The test was laboriously going through the sign cases; relocate the
QString::compare() test's sign() function so that we can use it here,
too, and simply QCOMPARE() signs. Introduce a TransientLocale class,
copied from tst_QLocale, to take care of setting and restoring the
locale using setlocale(). Change the locale name to a QByteArray so
that we save having to convert it to one in order to pass it to
setlocale(). Since that changed every _data() row, reformat those rows
in the process - most of them were long lines.

On the systems where we can't set the locale used by the function
being tested, condition each block of tests in the _data() on whether
LC_COLLATE looks like the locale to be tested, and report how a
determined developer at least can (by repeatedly running the test with
different locales set) test all the cases; and we'll attempt the ones
that we can, when one of the relevant locales is in use. If that
leaves us with no tests we can do, QSKIP() in the _data() to avoid an
assert failure for "Test data requested, but no testdata available."

cea662550e Turn tst_QString::setRawData()'s QSKIP into QEXPECT_FAIL()s
In commit 287ace562e, part of this test
was suppressed without filing a Jira ticket (or, at least, without
recording it in the QSKIP message). Since it's a known failure, it
should at least be a QEXPECT_FAIL, not a QSKIP. Since only some of the
subsequent parts of the test fail, I used QEXPECT_FAIL(,,Continue) on
each of the failing tests.

98666c8afc Change QString formatting of negative numbers in non-base-10

Additinally, this patch adds unit tests for QString::number.

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.

78cf89c07d Use checked string iteration in case conversions
The Unicode table code can only be safely called on valid code-points.
So code that calls it must only pass it valid Unicode data. The string
iterator's Unchecked Unchecked methods only provide this guarantee
when the string being iterated is guaranteed to be valid UTF-16; while
client code should only use QString, QStringView and friends on valid
UTF-16 data, we have no way to be sure they have respected that.

So take the few extra cycles to actually check validity in the course
of iterating strings, when the resulting code-points are to be passed
to the Unicode table look-ups. Add tests that case mapping doesn't
access Unicode tables out of range (it'll trigger the new assertion).
Added some comments to qchar.h that helped me understand surrogates.

76004502ba Get rid of shared null for QByteArray, QString and QVector
As a side effect, data() can now return a nullptr. This
has the potential to cause crashes in existig code. To work
around this, return an empty string from QString::data()
and QByteArray::data() for now.

For Qt 6 (and once all our internal issues are fixed), data()
will by default return a nullptr for a null QString, but we'll
offer a #define to enable backwards compatible behavior.

[ChangeLog][QtCore][QByteArray] Remove method overloads taking
QString as argument, all of which were equivalent to passing the
toUtf8() of the string instead.

44da43e8e4 QString: add char8_t overload of fromUtf8()
Use the overload-with-template trick from P1423 to avoid ambiguities
when existing callers pass 0 or nullptr.

Add a qdoc-ignored macro to hide the fact that the overload is a
template.

[ChangeLog][QtCore][QString] Added char8_t overload of fromUtf8().

aac39167b7 Add QStringView::split() methods
Since QString::split() is not going away in Qt 6, we should aim
to provide API symmetry here, and ease porting existing code from
QString(Ref) to use QStringView.

This is easier than having to port everything to use tokenize() at
the same time. tokenize() will however lead to better performance
and thus should be preferred.

2f05aa82e7 Adjust resize() behavior of QString and QByteArray to match Qt 5
resize() to a smaller size does not reallocate in Qt 5 if the container
is not shared. Match this here.

As a drive-by also fix resize calls on raw data strings to ensure
they are null terminated after the resize.

Even in Qt 5, remove() can be passed an alias to *this. In Qt 6, with
the advent of substring sharing, this will become even more
pronounced. Use the same fix as was already used in QString::insert().

594abde1a2 Enforce that statically allocated array-like containers have 0 capacity
It has been the case for both QStringLiteral and QByteArrayLiteral
since Qt 5.0, and Q_ARRAY_LITERAL since Qt 6.0.

Since it's definitely surprising, add a note in the docs, which
is "somehow" consistent with the interpretation of capacity as
the biggest possible size before we reallocate. Since it's 0,
any manipulation of the size will cause a reallocation.
(Alternatively: the capacity() is for how many elements memory was
requested from the free store. No memory was allocated, so 0...)
