c0c9e43be1 Add a special testcase for IndexedDB settings only
The test removes the file in memfs that IndexedDB settings use as the
backing store. This forces a new instance of IDB settings to read from
the actual IndexedDB, instead of the file.

91e70f239e Give QLocale::uiLanguages() a separator parameter
It has always returned dash-joined forms of the locale names, and
callers who need an underscore-joined form have been obliged to
replace('-', '_') before using them. Given that everything it adds to
the list comes from QLocaleId methods that accept a separator, it's
trivial to let it offer the same choice to its callers and save them
this hassle.

Amended code in QTranslater and QMimeType to save them that hassle.

[ChangeLog][CoreLib][QLocale] QLocale::uiLanguages() now lets the
caller choose what separator to use between the tags that make up each
locale-identifier in the list returned.

ccd8a496cf QXmlStreamReader::readNextStartElement() - return false on document end
The method reads the next element in a loop, as long as valid elements
exist. Within the loop, it returns
- false if the end of an element has been reached
- true if a new element has started

When the document end has been reached, the loop continues, until
readNext() returns Invalid. Then, PrematureEndOfDocumentError is launched.

This is wrong, because reading beyond the document end is caused by a
missing return condition in the loop.

=> Treat document end like element end and return false without
reading beyond it.

=> Test correct behavior in tst_QXmlStream::readNextStartElement()

9c1d20337a Remove QUuid(quint128) constructor again
This constructor matches way too many argument types (integral,
unscoped enums, FP types), so it's likely to cause mayhem, even if
left in as an explicit constructor.

We now have a named constructor for the same functionality, so just
drop the "unnamed" constructor.

"Unnamed" constructors are important when emplacement is more
efficient than construction + move, or when implicit conversion is
required.  Neither is the case here: The named as well as the
"unnamed" constructors just copy ten bytes around, and the compiler
can optimize those extra copies away just fine.

Found in API review.

f2f8820073 tests: port assorted trivial uses of Q_FOREACH to ranged for loops
All of these fall into the trivial category: loops over (readily made)
const local containers. As such, they cannot possibly depend on the
safety copy that Q_FOREACH performs, so are safe to port as-is to
ranged for loops.

There may be more where these came from, but these were the ones that
stood out as immediately obvious when scanning the 100s of uses in
qtbase, so I preferred to directly fix them over white-listing their
files with QT_NO_FOREACH (which still may be necessary for some files,
as this patch may not port all uses in that file).

1ae24f8b50 Use CLDR's names in QLocale::*ToName() for language, script, territory
Various comments need to continue using the enumdata.py names, as they
associate data with particular enum members, but we can now correctly
use the en.xml versions of their names when we report them, rather
than the enum-friendly names we use in the code. Since this now means
the data may stray outside plain ASCII - it'll be UTF-8-encoded - this
implies replacing the QLatin1StringView()s of the code that formerly
read this data with QString::fromUtf8().

d105c67a72 tst_QLocale: Use UTF-8 rather than Latin-1 for C-string-ification
Test names and output need to be UTF-8 for the XML data formats to not
end up malformed - which would upset Coin's testrunner, when it
validates the XML as part of checking - and the few other uses of
toLatin1() were to ASCII content anyway, so can harmlessly (this being
test code, where the slight performance advantage of Latin-1 doesn't
matter) use toUtf8() as well, for the sake of uniformity.

Use of toLatin1() broke an imminent commit in which some territory,
script and language names depart from ASCII, leading to malformed
UTF-8 when they appear in test-data-row names.

c5515f5eb1 Fix digit grouping: m_grouping_top doesn't mean what I thought it did
I'd previously understood CLDR's minimumGroupingDigits to mean the
most significant group must have that many digits. It turns out to
mean only that the first grouping separator doesn't get added unless
the more significant group has this many. Once we have one separator,
more can be added that do isolate a single digit.

In the process, I discover some of the prior arithmetic is incorrect;
it is now fixed. Added some basic testing, amended some existing
tests. In the process, fixed naming of some double validator tests.

d1da83002d QByteArray: remove a unittest
It relied on an implementation detail of operator+=(), that the latter
wouldn't just use assignement (e.g. if `this` is empty/null).

It also had undefined behavior, when the char array used with
fromRawData() went out of, the nested, scope, the code was pointing to a
dangling stack pointer.

Thanks to Thiago for the explanation in code review.

This ties in with further changes in this series, where append() is
changed to preserve null-ness; there is no way to preserve null-ness in
append() while keeping this unittest passing.

eb0abd9789 Use QT_SUPPORTS_INT128 macro to handle 128-bit integral types
Introduce QT_SUPPORTS_INT128 and QT_NO_INT128 marcos to handle 128-bit
types. These macros allow to undef Qt's own 128-bit types and the
related code, but keep the compiler definitions unchanged.

This is required for Qt Bluetooth, where we need to use
QT_BLUETOOTH_REMOVED_SINCE to get rid of the APIs using
QtBluetooth-specific struct quint128 which clashes with the 128-bit
types. The idea is to use QT_NO_INT128 in Qt Bluetooth's
removed_api.cpp instead of directly undef'ing __SIZEOF_INT128__,
because the latter is UB.

This commit amends befda1acca.

2e9d33e534 Use correct index for QLocale::system()'s static
Nothing prevents client code from calling QLocale::setDefault() before
we ever instantiate QLocale::system() - aside from some quirks that
mean setDefault(), currently, does instantiate QLocale::system() to
force initialization of defaultLocalePrivate - so using defaultIndex()
could set the system QLocalePrivate instance's index incorrectly.

In any case, even if the index is initially set correctly, a
subsequent change to the system locale would change the correct index;
and nothing outside QLocale::system() has access to the instance that
would then be remembering an out-of-date index.

Actually tripping over that inconsistency took some deviousness, but
was possible. The index is (currently) only used for month name
lookups and those special-case, for the Roman-derived calendars, the
system locale, to only use the index if the system locale offers no
name for a month. Meanwhile, updateSystemPrivate() uses the fallback
locale's index for its look-up of which CLDR data to copy into the
fallback QLocaleData for the system locale.

None the less, a non-Roman calendar's lookup will go via the index to
get at the CLDR data for that calendar, thereby exposing the system
locale's index to use; and, sure enough, a setDefault() could lead
that to produce wrong answers.

In QLocale::system() there's a cached QLocalePrivate, whose index we
need to ensure stays in sync with the active system locale. So pass
its &m_index to systemData(), which will now (when passed this) ensure
it's up to date. Since we always have called systemData(), to ensure
it is up to date, we can skip that update in the initialization of the
cached private and use m_index = -1 to let systemData() know when it's
in the initial call, thereby making the static cache constinit.

Amended a test to what proved the issue was present.

309e7d88c3 QStringBuilder: test more concatenation variants
- rvalues, they work due to e.g. the implicit conversion to QString, so
  the compiler picks the "const String &" overloads. (This may change by
  adding rvalue overloads in a later commit, although that will mean
  adding many more operator+() overloads to disambiguate the calls)
- QByteArray + QByteArrayView
- More P and more Q (even though in some cases P and Q are defined as
  the same operator in some QStringBuilder unittest "scenarios")

4b0261fed0 tst_QFuture: fix UB (call of member function on wrong object)
By the time QObject::destroyed() is emitted from ~QObject(), sender no
longer is-a SenderObject, only a QObject, so calling a SenderObject
member function on it is UB.

Says UBSan:

    tst_qfuture.cpp:3854:84: runtime error: member call on address 0x60200000e550 which does not point to an object of type 'SenderObject'
     0x60200000e550: note: object is of type 'QObject'

                   ^~~~~~~~~~~~~~~~~~~~~~~
                   vptr for 'QObject'

Fix by removing the QObject::connect().

This, of course, breaks the test's WHEN, but I don't see how to keep
that WHEN without the UB. At least the THEN part is not invalidated,
and there doesn't appear to be another test that tests that destroying
objects before signal emission results in a cancelled future.

f82cf6333e Long live QSpan!
QSpan is Qt's version of std::span. While we usually try not to
reimplement std functionality anymore, the situation is different with
QSpan. Spans are non-owning containers, so the usual impedance
mismatch between owning STL and Qt containers doesn't apply here:
QSpan implicitly converts to std::span and vice versa, making STL and
Qt APIs using spans completely interoperable.

We add QSpan mainly for two reasons: First, we don't want to wait
until we require C++20 in Qt and can use std::span. Second, in the
view of this author, some design decisions in std::span hurt the
primary use-case of spans: type-erasure for containers. This results
in two major deviations of QSpan from std::span: First, any rvalue
container is convertible to QSpan, allowing seamless passing of owning
containers to functions taking spans:

    void sspan(std::span<T>);
    void qspan(QSpan<T>);

    std::vector<T> v();
    sspan(v()); // ERROR: rvalue owning container
    auto tmp = v();
    sspan(tmp); // OK, lvalue
    qspan(v()); // OK

This author believes that it's more helpful to have compilers and
static checkers warn about a particular wrong usage than to make
perfectly valid use-cases impossible or needlessly verbose to code.

The second deviation from std::span is that fixed-size span
constructors are also implicit. This isn't as clear-cut, because an
explicit QSpan{arg} isn't per-se bad. However, it means you can't
transparently change from a function taking decltype(arg) to one
taking QSpan and back. Since that's exactly what we intend to do in Qt
going forward, in the interest of source-compatibility, the ctors are
all implicit.

Otherwise, the API of QSpan follows the std::span API very
closely. Like std::span, QSpan isn't equality_comparable, because it's
not clear what equality means for spans (element-wise equal, or (ptr,
size)-wise equal?). The major API additions are Qt-ish versions of std
API functions: isEmpty() on top of empty() and sliced() instead of
subspan(). The (nullary) first()/last() functions (Qt speak for
front()/back()) clash with the std::span function templates of the
same name, so are not provided.

This patch adds QSpan as private API. We intend to make it public API
in the future.

ca6a0fd63f QDTP: match local-time by preference to its zone
When parsing a string whose time-zone part matches local time's name,
use local time in preference to the QTimeZone with that name. The case
is ambiguous, and the bug was already fixed (by something else) in
dev, but this caused a failure in 6.2 through 6.5; and using local
time is more natural to QDateTime in any case. The fix incidentally
makes the the logic of the zone-resolution code more straightforward
and a closer match to how findTimeZone() found the match.

The issue was hidden from 6.6 by a change [*] to the handling of POSIX
rules, that lead to plain abbreviations such as CEST and BST - for
which the IANA DB has no entry - no longer being considered "valid"
zones, despite being technically valid POSIX zone descriptors
(effectively as aliases for UTC).

Although QSystemLocale is (to make its query enum usable) defined
despite the QT_NO_SYSTEMLOCALE define, it's not used in that case, so
tests based on it won't work. So extend the reach of the #if-ery to
include the test using a custom class based on it. Also rename the
test from systemLocale(), as that's the name the emptyCtor() test
really should have.
