Ivan Solovev 7068418a13 QByteArray: use comparison helper macros
Replace the existing friend relational operators with the macros.
Add the previously-missing relational opertors with QChar and char16_t.

This allows to remove the last dummy relational operators and the
macros to generate them in tst_qstringapisymmetry.

Because of a bug in libstdc++[0], we have to explicitly keep the
QBA vs QBA relational operators even in C++20 mode. This problem is
specific to QByteArray, because it is convertible to const void *.

Ivan Solovev ee612626f9 Q(Latin1)Char: use comparison helper macros
Replace the existing friend relational operators with the macros.

Add the previously-missing QChar vs `const char *` relational operators.
These require out-of-line helper methods, because we need to interpret
the `const char *` array as utf-8.
The `const char *` relational operators cause ambiguities when
comparing QChar with 0 (previously it was only handled by the nullptr_t
overloads). As we have it in several places in our tests, I'd assume
that the users can also do it. To resolve the ambiguities, mark the
new relational operators as Q_WEAK_OVERLOADs.

This allows to remove the dummy QChar vs `const char *` relational
operators from tst_qstringapisymmetry, but at the same time requires
that we introduce new dummy operators for QByteArray vs char16_t
comparison. These will be fixed in a follow-up patch.

For QLatin1Char - convert to uchar before doing the comparison, to
match the behavior of QLatin1StringView and QChar. Extend QChar's
unit tests.

Ivan Solovev e2e21bcb2d QString: use comparison helper macros - missing string views [3/3]
The comparison with QStringView works as is, there is no need to add
explicit operators.
Add the missing relational operators with QUtf8StringView. Once it
is added, comparison of QString with u8"string literal" becomes
ambiguous, so explicitly add operators for `const char8_t*` as well.
This also makes the comparison with u8 string literals faster,
because it now uses a view instead of constructing a QString.

Adding QUtf8StringView overloads also makes comparison with
`const char *` ambiguous if QT_RESTRICTED_CAST_FROM_ASCII is defined.
To fix that, mark the overload as Q_WEAK_OVERLOAD. Luckily, we can
just use the third Attributes parameter of the macro for that.

Provide more unit-tests to cover the new relational operators.

Ivan Solovev 77bec4f7c8 Simplify QLatin1StringView vs byte array relational operators
Now when QLatin1StringView implements relational operators with
QByteArrayView in terms of new comparison helper macros and helper
methods taking QByteArrayView, we can easily re-use these helper
methods to provide comparison with QByteArray and const char *.

QLatin1StringView already provided almost all of these operations,
partly as hidden friend functions, partly as inline methods.
Since the class is not exported, and the methods were inline, we
can just remove all of them and replace them with the comparison
helper macros.

This should speed up the relational operators, because they do not
construct string objects using QString::fromUtf8() anymore, but use
QUtf8StringView instead.

This also adds the previously missing QByteArray vs QLatin1StringView
relational operators.

... by using the new comparison helper macros.

Also, convert the existing QByteArrayView relational operators to use

An attempt to define the helper functions comparesEqual() and
compareThreeWay() as hidden friends leads to compilation errors, because
the QByteArrayView(QLatin1StringView) constructor gets somehow disabled.
Apparently, it cannot satisfy the
QtPrivate::IsContainerCompatibleWithQByteArrayView trait anymore.
I could not find a reason for that, so I just defined the helper
functions as static inline private members of QByteArrayView. This fixes
the issue.

We also have to deal with trailing data at the end of our sliding window
potentially causing issues for the encoding. So we try to shrink our
window when it causes issues, or store the trailing data for the next
call.

QCOMPARE() can report enum values by name just fine, no need to
laboriously convert them to strings. While comparing all tags in one
go did allow a more comprehensive report, it's enough to know we

all those extra details if we get a failure.

Testing qHash() doesn't distinguish equal things is fairly low value;
at least avoid duplicating the construction of the reference value.

for ordered and different comparisons.

* Tamil locales now have something of a mix of inherited and localized

  there.
* Checks that various combinations of language, script and territory

* A test that territory is preserved when it's the only given tag

Thiago Macieira d351a97e85 QString::arg: don't pass nullptr to memcpy()
A null QString / QStringView has a null begin pointer stored as its
array beginning (something we hide a little in the QString::data()
function, but not in QStringView::data()). We've been passing a null
pointer to memcpy() every time someone passed a null QStringView for
QString's single-argument arg() call, though not the multi-string arg()
version (which is the only one QStringView offers).

Commit f5021835df made this worse by
making QStringViews created from null QStrings retain the nullness (as
was intended).

Thiago Macieira f5021835df qTo*ViewIgnoringNull: further ignore nulls
Commit ba5db13c8d ("QStringView: add
internal qToStringViewIgnoringNull()") said:

  As long as a null QString still returns non-null data(), QStringView's
  QString constructor needs to call isNull(). That's a branch we often
  can do without, so add an internal function that bypasses this
  correctness check.

  It's internal, since we might have a Q6String that returns nullptr
  data() when null, which will remove the need for this function.

For Qt 6, we made QString and QByteArray be able to return nullptr from
data() when null... but that's not enabled by default yet. However, the
begin() functions do return nullptr, so we can avoid the extra branch
the commit was talking about.

Edward Welbourne 58fd829cdf Use localized time-zone abbreviations or offset
The actual formatting of date-time strings is handled by the calendar
backend, but the code's in qlocale.cpp as it uses some of its tools.
When feature timezone is unavailable, we're stuck (as before) with
using QDateTime::timeZoneAbbreviation(), but when it's available we
can use QTimeZone::displayName() to get the localized form of the
abbreviation and offset string.

Make matching changes in QDTP so that it recognizes these localized
abbreviations. We now have another candidate for what local time might
be called, to add to those that must be checked.

This naturally implied some changes to tests. It turns out ICU
believes en_US uses GMT+1/GMT+2 for CET/CEST. Replace some MS
QEXPECT_FAIL()s by including the non-abbreviations we do in fact use
on MS in the lists of "abbreviations" to accept.

[ChangeLog][QtCore][QLocale] When a datetime format includes the
timezone (or offset), the appropriately localised form is (to the
extent the timezone backend in use supports this) used where,
previously, a haphazard choice of system and C locale was used. This
applies to both serialization and parsing.

Edward Welbourne 1e74f67e54 Work round ICU disagreeing with TZDB about zone transitions
Since the TZ backend resorts to ICU for display names, we got
inconsistent results if they disagree about when transitions happened.
Also, ICU uses the current (or only recent history) names for the
zone, so one currently not doing DST (Africa/Tripoli) doesn't get a
report of its DST name at a historical time when it did DST (but ICU
doesn't know about it). Since the ICU backend, in any case, doesn't
override the displayName(qint64, ...), we can simply use the QTZP base
version instead of overloading in the TZ back-end, so we only delegate
to ICU when it might actually help. This also saves duplicating some
locking and lazy-initialization code.

In the process, turn a unique lock into a scoped lock within a
suitable scope. Also, make a comment more grammatical and less
verbose.

Dennis Oberst b134718c11 QString: use new assign() in operator=({QByteArray, QChar, char *})
operator=(~) and assign() share similar names but, until now, have not
shared the same functionality. This patch introduces the usage of
QString::assign() within the non-sharing assignment operators to
effectively boost efficiency by reusing the available capacity.

Since we're re-using the capacity we update the test case in places
where they don't hold true anymore.

Since these assignment operators are frequently used in many places,
both within Qt and non-Qt code, this patch comes with benchmarks.

The preview of the benchmark results are compared with this patch and
before this patch. The results show a boost in performance for the
QByteArray and 'const char*' overload. The QLatin1StringView overload
already preserved the capacity and has a better performance than the
assign() alternative, so don't us it there.

Mårten Nordheim 4660a230d5 QString/QByteArray: fix append() wrt. raw data
When appending to an empty string or byte array, we optimize and
copy the internal pointer. But if the other string/byte array was
created with fromRawData this might be temporary data on the stack/heap
and might be de-allocated or overwritten before the string/byte array
is used or is forced to make a deep-copy. This would lead to incorrect
data being used.

This is easy to overlook if you plan to append multiple strings
together, potentially supplied through an argument. Upon appending a
second string it would make a full copy, but there might not be a
guarantee for that. So, it's hard for users to avoid this pitfall!

Edward Welbourne 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.

Giuseppe D'Angelo 96d67da420 String-like containers: add implicit conversions towards std:: string views
In C++20 std::basic_string_view has gained a range constructor (like
QStringView always had), but that range constructor has been made
explicit. This means we can't just pass a QString(View) to a function
taking a u16string_view. The consensus seems to be that that types that
should implictly convert towards stdlib's string views should do that
via implicit conversion operators. This patch adds them for

* QByteArrayView => std::string_view
* QString(View) => std::u16string_view
* QUtf8StringView => std::string_view or std::u8string_view, depending
  on the storage_type

QLatin1StringView doesn't have a matching std:: view so I'm not enabling
its conversion.

QByteArray poses a challenge, in that it already defines a conversion
towards const char *. (One can disable that conversion with a macro.)
That conversion makes it impossible to support:

  QByteArray ba;
  std::string_view sv1(ba);  // 1
  std::string_view sv2 = ba; // 2

because:

* if only operator const char *() is defined, then (2) doesn't work
  (situation right now);

* if both conversions to const char * and string_view are defined, then
  (1) is ambiguous on certain compilers (MSVC, QCC). Interestingly
  enough, not on GCC/Clang, but only in C++17 and later modes.

I can't kill the conversion towards const char * (API break, and we use
it *everywhere* in Qt), hence, QByteArray does not get the implicit
conversion, at least not in this patch.

[ChangeLog][QtCore][QByteArrayView] Added an implicit conversion
operator towards std::string_view.

towards std::u16string_view.

[ChangeLog][QtCore][QStringView] Added an implicit conversion operator
towards std::u16string_view.

[ChangeLog][QtCore][QUtf8StringView] Added an implicit conversion
operator towards std::string_view (QUtf8StringView is using char
as its storage type in Qt 6). Note that QUtf8StringView is planned to
use char8_t in Qt 7, therefore it is expected that the conversion will
change towards std::u8string_view in Qt 7.

Edward Welbourne 95a74de486 Add tests of QLocale's toDate() and toTime()
Previously only toDateTime() was tested. Adding a test-case for
toTime() provoked adding full testing for both it and toDate(), based
on toDateTime() tests.

Pick-to: 6.6 6.5

Marc Mutz b2b5862479 QAnyStringView: add QDebug stream operator
When QDebug::quoted(), indicates the encoding using the u/u8 prefixes
or the _L1 suffix. This is information that might come in handy, and
we plan to make it off-switchable (QTBUG-114936). The default should
be true, though, for QAnyStringView, because we should confront users
with this feature so they learn it exists. For concrete view types,
changing the default behavior is probably not a good idea.

[ChangeLog][QtCore][QAnyStringView/QDebug] Can now stream
QAnyStringView into QDebug.

Fixes: QTBUG-114935
