577d698b8e changed QString::isUpper /
isLower behaviors to match Unicode semantics: a string is uppercase
if it's identical to its own toLower/toUpper folding. These semantics
come from Unicode so they're not up for debate.
That commit however left QByteArray untouched. Generally speaking, we
want to move away from QByteArray as "text storage" -- this has
partially happened between Qt 5 and Qt 6, where QByteArray went from
Latin-1 semantics to ASCII semantics. Still, QByteArray offers
toUpper/toLower and isUpper/isLower and all this family of functions
should be consistent in behavior.
Apply the same fix that was applied to QString.
[ChangeLog][Important Behavior Changes] The semantics of
QByteArray::isLower() and QByteArray::isUpper() have been changed. Now
lowercase (resp. uppercase) byte arrays are allowed to contain any
character; a byte array is considered lowercase (resp. uppercase) if
it's equal to its own toLower() (resp. toUpper()) folding. For instance,
the "abc123" byte array is now considered to be lowercase.
Previously, the isLower() (resp. isUpper()) functions checked whether
the byte array only contained ASCII lowercase (resp. uppercase)
characters, and was at least 1 character long. This had the side effect
that byte array containing ASCII non-letters (e.g. numbers, symbols,
etc.) were not lowercase nor uppercase.
[ChangeLog][QtCore][QByteArray] QByteArray::isLower() and
QByteArray::isUpper() now work correctly with empty byte arrays. The
semantics of these functions have been changed.

Unlike QString and QStringView, QByteArrayView and QByteArray don't
overload well.
Solve the overload issue the usual way: by making the QByteArray one a
Q_WEAK_OVERLOAD. This is trivial for QStaticByteArrayMatcher, which
isn't exported, but require QT_REMOVED_SINCE magic for
QByteArrayMatcher, which is.
The additional const char* overload has shielded us from the worst
fall-out so far, it seems, but it makes for a truly horrible overload
set:
matcher.indexIn(str, 3);
Q: Is the 3 here the length of the haystack or the value of the from
parameter?
A: It depends on decltype(str)!
If the (const char*, qsizetype, qsizetype=0) overload is the better
match, then 3 limits the haystack's length.
If, otoh, the (QByteArray(View), qsizetype) overload is the better
match, then it's the value of the from parameter.
As if this wasn't bad enough, QByteArray implcitly converts to const
char* by default!
A follow-up patch will therefore deprecate the (ptr, size) overloads,
so we de-inline the QByteArrayView ones to avoid having to touch the
implementation once more.

The above commit made the mistake of relying on the 30yr+ old
fundamental relation
size() - capacity() == freeSpaceAtEnd()

broke. Because of that, while size() - capacity() may be large enough
to hold the new data, if freeSpaceAtBegin() > 0, then freeSpaceAtEnd()
may not.
Fix by inspecting freeSpaceAtEnd() instead of capacity(). The

adds freeSpaceAtBegin() to the requested size, which is why the

The only documented replacements for Q*String*::arg() are sequences like
%1, %2, %3 -- where the n-th number is expressed using a sequence of
ASCII digits [1].
The code parsing the replacements however used the QChar::digitValue()
function. That function simply checks if a QChar has a *Unicode digit
value* (no matter what its block/category is), and if so, returns the
corresponding digit value as an int (otherwise returns -1).
The result of this is that a sequence like "%¹" or "%१" actually
triggered substitutions (both count as "1"). Similarly, QChars with
a digit value would be parsed as part of longer sequences like "%1²"
(counting as "12" (!)).
This behavior is weird, undocumented, and extremely likely the usual
backstabbing by Unicode by using "convenience" QChar methods -- that is,
never *intended* by the implementation.
This commit deprecates (via warnings) such usages, which for the time
being are left working as before (in the name of backwards
compatibility). At the same time: given it's extremely unlikely that
someone would be deliberately relying on this behavior, it implements
the desired change of behavior (only accept sequences of ASCII digits)
starting from Qt 6.6, that is, after the next LTS.
Throughout Qt 6's lifetime users will still be able to control arg()'s
behavior by setting an env variable, but that variable (and the support
for Unicode digits) will disappear in Qt 7.
To summarize:
* Qt 6.3->6.5: default is Unicode digits, env var to control
* Qt 6.6->6.x: default is ASCII digits, env var to control
* Qt 7: only ASCII digits, no env var
[1] That's the name Unicode gives to them, cf. https://www.unicode.org/charts/PDF/U0000.pdf
[ChangeLog][QtCore][Deprecation Notices] The arg() functions
featured in Qt string classes have always been documented to require
replacements tokens to be sequences of ASCII digits (like %1, %2, %34,
and so on). A coding oversight made it accept sequences of arbitrary
characters with a Unicode digit value instead. For instance, "%2੩" is
interpreted as the 23rd substitution; and "%1²" is interpreted as the
12th substitution. This behavior is deprecated, and will result in
runtime warnings. Starting from Qt 6.6, arg()'s behavior will be changed
to accept only ASCII digits by default. That means that "%1²" is going
to be interpreted as substitution number 1 followed by the "²" character
(which does not get substituted, so it gets left as-is in the result).
Users can restore the previous semantics (accept Unicode digits) by
setting the QT_USE_UNICODE_DIGIT_VALUES_IN_STRING_ARG environment
variable to a non-zero value. In Qt 7, arg() will only support sequences
of ASCII digits. Note that from Qt 6.3 users can also set
QT_USE_UNICODE_DIGIT_VALUES_IN_STRING_ARG to zero; this will make arg()
use ASCII digits only, in preparation for the future change of defaults.

QLocale and QString tests had copies of a TransientLocale; we've
recently improved the QLocale one. Rather than duplicating those
rather complicated improvements, finally share a common version.
In the process, I noticed that setlocale() only returns the prior
value when passed nullptr as the new value; so rework the
implementation to get that right, so that it now correctly restores
the prior locale. That, in turn, means there's now a later call to
setlocale(), when we actually set the changed setting, which may
invalidate the earlier return; so copy it to a QByteArray before the
second call.
Included Ivan Solovev's improved version of how to reset the locale,
since TransientLocale needs it.

The name of is_utf8_encoded type seems to imply that QByteArray and
const char * contain UTF-8 encoded data. This is not always the case.
When used with QByteArray API, those types are handled as containing
ASCII-only. It's only when used with APIs of other classes (QString,
QLatin1String) they are handled as UTF-8. This renames the check to
is_bytearray_like_v and clarifies its usage. No need to handle
QUtf8StringView this way because it works just fine with the current
testcases.
While at it, also remove unused is_latin1_encoded trait.

The existing a, ap, A and AP specifiers all force the case of the
formatted am/pm indicator. The indicators returned by QLocale's
amText() and pmText() methods are those given in CLDR, with no case
coercion. Application writers may reasonably want these strings used
verbatim, rather than having to chose a case and impose it on the
locale's indicators, in defiance of national custom. For example,
while en_US uses upper-case indicators by default, cs_CZ uses
lower-case ones. An application author writing a time format has been
forced to chose which of these locales to be wrong in.
Add support for aP and Ap specifiers, whose mixed case indicates that
the locale's case is to be respected. Amend an existing test-case of
tst_QLocale's formatDateTime() that used Ap (expecting, of course, an
upper-case indicator followed by a stray p) to now expect the
locale-appropriate-cased indicator. Extend formatTime() to test cases
using aP and Ap, to illustrate the difference between en_US and cs_CZ.
Rework QDateTimeParser to also support the new format specifier. This
required expanding its Case enum, used by the getAmPmText() method,
which was formerly shared with QDateTimeEditPrivate; however, as that
class no longer makes any reference to this method, it and the enum
can be made private, allowing a systematic clean-up of their use.
Added test-cases for both serialization and parsing; and amended some
existing parsing tests to verify am/pm indicators are matched
case-insensitively.
[ChangeLog][QtCore][Important Behavior Changes] Time formats used by
QLocale, QTime and QDateTime's parsing and serialization now recognize
'aP' and 'Ap' format specifiers to obtain an AM/PM indicator, using
the locale-appropriate case for the indicator, where previously the
author of a time format had to pick a case that might conflict with
the user's locale. For QTime and QDateTime the locale is always C,
whose indicators are uppercase. For QLocale, the case will now match
that of amText() or pmText(). Previously, 'aP' would have been read as
a lower-case indicator followed by a 'P' and 'Ap' as an upper-case
indicator followed by a 'p'. The 'P' or 'p' will now be treated as
part of the format specifier: if the prior behavior is desired, either
use 'APp' or 'apP' as format specifier or quote the 'p' or 'P' in the
format. The prior 'a', 'ap', 'A' and 'AP' specifiers are otherwise
unaffected.

It was previously calling setlocale(), which makes no difference to
the Unix backend for the system locale, since that's based on
environment variables (that would normally be used to get default
values for the various setlocale() categories, but only the first time
each is asked for). So, on Unix, set the environment variable, too.
It's also necessary to instantiate a QSystemLocale instance
transiently to trigger a refresh of the system locale data.

We have previously been using the standalong (nominative) month names
both when asked for that and when asked for the plain (genitive) month
name, probably because there was no LCTYPE value for the
latter. However, MS's docs for the standalone values do contain a
comment telling us how to get the genitive names.
Rename the old monthName() to standaloneMonthName() and add a
monthName() that calls GetDateFormat() suitably, as described by the
MS doc.
