Thiago Macieira ae44b283a9 tst_QStringConverter: compare pointer distances, not pointers
Strictly speaking, we did want to compare pointers, but char* are
special with QCOMPARE in that the pointed-to strings are compared, not
the pointers. So this wasn't doing what we wanted it to do.

We could static_cast to void* to do it, but subtracting one from the
other also gets us what we want, with simpler code. The drawback is that
if appendToBuffer() ever returns nullptr, we'll print a huge number as
the offset.

Marc Mutz 88b1c96239 QAnyStringView: fix char-ish ctors to not allocate memory
Extending the fromCharacter() tests to check for the construction to
be noexcept and implicit turned up a few bugs:

The constructor from char32_t was simply not marked as noexcept, even
though all its operations were. So just mark it noexcept.

The constructor from QChar, otoh, was never called, (certainly not for
rvalues), because QString happens to be constructible from QChar (and
QLatin1Char and QChar::SpecialCharactor), so due to perfect
forwarding, the if_convertible_to<QString> ctor won, allocating a
QString.

This is a regression of Qt 6.5 compared to Qt 6.4.

To fix this, exclude arguments that convert to QChar from matching the
if_convertible_to<QString/QByteArray> ctors, taking care to not match
those arguments that are already compatible_char<>s.

This, in turn, creates a problem for implicit QASV construction from
QLatin1Char and QChar::SpecialCharacter, because now that we've
excluded them from the if_convertible_to<QString> ctor, calling the
existing QChar or QString non-template constructors for these types
would require two user-defined conversions (from said type to
QChar/QString and from QChar/QString to QAnyStringView). That works
for explicit construction, but we need implicit convertability.

So bring out the big guns once more and add a perfectly-forwarding
ctor for anything convertible to QChar. QChar itself is actually
already handled by compatible_char<>, so the old QChar non-template
ctor can go. The extra copy of the QChar argument will be optimized
away by the compiler.

[ChangeLog][QtCore][QAnyStringView] Fixed a regression where
constructing a QAnyStringView from a char-like type (QChar,
QLatin1Char, ...) would first construct a QString and only then
convert that to QAnyStringView.

Amends 812a0d3125.

This change is forward and backward BC and SC, but not
behavior-compatible: certain operations detectably change
noexcept'ness, and some arguments may now cause the resulting
QAnyStringView to have a different encoding (though I really tried
hard to avoid that).

Since it's a regression, I proposed to pick this to the affected
branches, 6.7 and 6.5 (6.6 is already closed at this point).

Marc Mutz 564be117fe tst_QByteArrayView: expose constExpr() test to non-ubsan GCC builds
Because of https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71962, and
because marking constExpr() as __attribute__((no_sanitize_undefined))
doesn't fix a thing, we opted to disable the triggering parts of
constExpr() from all GCC builds.

This is, of course, unfortunate, since it meaningfully reduces
compile-time coverage in the general case for a rather obscure build
type most won't ever use.

While GCC doesn't give us a predefined macro to check for in the .cpp
file, the cmake build system knows whether we use ubsan, so just
define a macro of our own.

As a drive-by, simplify GCC detection by using Q_CC_GCC_ONLY.

match.

follow the CLDR data in handling timezones. In most cases this means

taking multiple QString-like arguments is now fixed to interpret

Both qlocale_mac.mm and dateconverter.py were mapping the CLDR am/pm

Edward Welbourne d778d17b9f Cope with CLDR's "day period" format specifiers
The LDML spec includes a 'b' pattern character which is like the 'a'
pattern, for AM and PM, but would rather use noon and midnight
indicators for those specific times. We don't support those and using
am/pm will be right enough of the time to be better than simply
discarding this option, if it ever gets used (which it currently
isn't), so treat as an alias for 'a'. No locale in CLDR currently uses
this.

CLDR also has a 'B' specifiers for "flexible day periods", including
things like "at night" and "in the day". At present only zh_Hant uses
'B'. As a result, this change only affects zh_Hant's formats for time
and datetime, which only zh_Hant_TW uses - zh_Hant_HK overrides them
to use am/pm markers and zh_Hant_MO inherits that from
zh_Hant_HK. Based on this and user feed-back, I've opted to treat 'B'
as another synonym of 'a'.

This removes an entry from the time_format_data[] table (it happened
to occupy one whole twelve-character row), causing many other locales'
offsets into that table to be shifted by 12. Only zh_Hant_TW has an
actual change to which entry in the table it uses.
Added a test-case.

[ChangeLog][QtCore][QLocale] CLDR's 'B' (flexible day period, e.g. "at
night" &c.) field, not currently supported, is now handled as a
synonym for the AM/PM field 'a', instead of leaving the B as literal
text. Only affects zh_TW at present.

Explicitly add the missing compareThreeWay() and comparesEqual()
overloads.

Note that relational operators were never affected by this problem,
because in C++17 mode we explicitly generate the reversed versions,
and in C++20 mode the compiler does that for us.

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.

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.
