When a needle has length 1 (because it's a QChar/char16_t, or because
it's a string-like of length 1) then an ad-hoc search algorithm is
used. This algorithm had a off-by-one, by not allowing to match at
the last position of a haystack (in case `from` was `haystack.size()`).
That is inconsistent with the general search of substring needles
(and what QByteArray does). Fix that case and amend wrong tests.
This in turn unveiled the fact that the algorithm was unable to cope
with 0-length haystacks (whops), so fix that as well. Drive-by, add a
similar fix for QByteArray.

When assigning multiple variables to a specific section, both GCC
and Clang legitimately error out if those variables wouldn't end
up in the same section (e.g. if one of them is going to a read-only
section while the other one is going to a read-write section).
In C++, when a seemingly const variable needs dynamic initialization,
it needs to be stored in a read-write section.
Clang 13 changed internals for how some constants are materialized.
Now, when a variable is initialized with an expression containing
plain old fashioned casts, it is considered to be potentially
runtime initialized (at the point when section assignment conflicts
is evaluated). Therefore, Clang 13 errors out on fakeplugin.cpp
with errors like:
fakeplugin.cpp:36:39: error: 'message' causes a section type conflict with 'pluginSection'

See https://bugs.llvm.org/show_bug.cgi?id=51442 for discussion

To simplify things, just initialize the fake pointers as regular
uintptr_t instead, avoiding the whole matter. This produces the

An empty QString(View) is allowed to have nullptr as its data pointer
(of course, only if its size is 0). This wasn't properly
checked in QRegularExpression, which passed such nullptr to
PCRE, and that resulted in PCRE raising an error (PCRE_ERROR_NULL).
Detect this case and pass a dummy pointer to keep PCRE happy.
Fixing and testing this in turn exposed a problem with QStringView
support in QRegularExpression when used over a null QString: the
code is supposed to use the QStringView(QString) constructor and NOT
qToStringViewIgnoringNull. That's because QRE distinguishes null
and empty subjects; when using qToStringViewIgnoringNull over
a null QString, one gets a non-null QStringView (!). Again, this in
turn exposed a problem with a QRegularExpression autotest that assumed
that a null match could only mean "no match" (instead, it can happen at
position 0 of a null QString(View)).

When trying to fix 0-length matches at the end of a QString,
be83ff65c4 actually introduced a
regression due to how lastIndexOf interprets its `from` parameter.
The "established" (=legacy) interpretation of a negative `from` is that
it is supposed to indicate that we want the last match at offset `from +
size()`. With the default from of -1, that means we want a match
starting at most at position `size() - 1` inclusive, i.e. *at* the last
position in the string. The aforementioned commit changed that, by
allowing a match at position `size()` instead, and this behavioral
change broke code.
The problem the commit tried to fix was that empty matches *are* allowed
to happen at position size(): the last match of regexp // inside the
string "test" is indeed at position 4 (the regexp matches 5 times).
Changing the meaning of negative from to include that last position (in
general: to include position `from+size()+1` as the last valid matching
position, in case of a negative `from`) has unfortunately broken client
code. Therefore, we need to revert it. This patch does that, adapting
the tests as necessary (drive-by: a broken #undef is removed).
Reverting the patch however is not sufficient. What we are facing here
is an historical API mistake that forces the default `from` (-1) to
*skip* the truly last possible match; the mistake is that thre is simply
no way to pass a negative `from` and obtain that match. This means that
the revert will now cause code like this:
str.lastIndexOf(QRE("")); // `from` defaulted to -1
NOT to return str.size(), which is counter-intuitive and wrong. Other
APIs expose this inconsistency: for instance, using
QRegularExpressionIterator would actually yield a last match at position
str.size(). Similarly, using QString::count would return `str.size()+1`.
Note that, in general, it's still possible for clients to call
str.lastIndexOf(~~~, str.size())
to get the "truly last" match.
This patch also tries to fix this case ("have our cake and eat it").
First and foremost, a couple of bugs in QByteArray and QString code are
fixed (when dealing with 0-length needles).
Second, a lastIndexOf overload is added. One overload is the "legacy"
one, that will honor the pre-existing semantics of negative `from`. The
new overload does NOT take a `from` parameter at all, and will actually
match from the truly end (by simply calling `lastIndexOf(~~~, size())`
internally).
These overloads are offered for all the existing lastIndexOf()
overloads, not only the ones taking QRE.
This means that code simply using `lastIndexOf` without any `from`
parameter get the "correct" behavior for 0-length matches, and code that
specifies one gets the legacy behavior. Matches of length > 0 are not
affected anyways, as they can't match at position size().
[ChangeLog][Important Behavior Changes] A regression in the behavior of
the lastIndexOf() function on text-related containers and views
(QString, QStringView, QByteArray, QByteArrayView, QLatin1String) has
been fixed, and the behavior made consistent and more in line with
user expectations. When lastIndexOf() is invoked with a negative `from`
position, the last match has now to start at the last character in the
container/view (before, it was at the position *past* the last
character). This makes a difference when using lastIndexOf() with a
needle that has 0 length (for instance an empty string, a regular
expression that can match 0 characters, and so on); any other case is
unaffected. To retrieve the "truly last" match, one can pass a
positive `from` offset to lastIndexOf() (basically, pass `size()` as the
`from` parameter). To make calls such as `text.lastIndexOf(~~~);`, that
do not pass any `from` parameter, behave properly, a new lastIndexOf()
overload has been added to all the text containers/views. This overload
does not take a `from` parameter at all, and will search starting from
one character past the end of the text, therefore returning a correct
result when used with needles that may yield 0-length matches. Client
code may need to be recompiled in order to use this new overload.
Conversely, client code that needs to skip the "truly last" match now
needs to pass -1 as the `from` parameter instead of relying on the
default.

The QtTest best practices documentations recommends using output

and this is also what most of our own tests do.
The QWARN() macro and corresponding internal QTest::qWarn() function
was added when QtTest was first implemented, but was likely meant as
an internal implementation detail, like its cousin QTestLog::info(),
which does not have any corresponding macro.
This theory is backed by our own QtTest self-test (tst_silent)
describing the output from QWARN() as "an internal testlib warning".
The only difference between QWARN() and qWarning(), besides the much
richer feature set of the latter, is that qWarning() will not pass

Remove the QString/QStringView/QLatin1String/const char* overloads
from the API, but not the ABI.
As a drive-by, replace a use of QStringView::left() by truncate(), as
suggested by a comment.
[ChangeLog][QtCore][QUuid] The from-string constructor and the
fromString() function now take QAnyStringView (was: overload set with
a subset of QString, QByteArray, const char*, QLatin1String,
QStringView each).

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

This patch fixed two bugs in indexOf/lastIndexOf:
1. The lastIndexOf(char, qsizetype) overload was crashing with an empty
QByteArray. It was unconditionally calling lastIndexOfCharHelper()
which assumes that this QBA is not empty. An explicit check for
the empty case is added.
2. The indexOf(QByteArray, qsizetype) overload was behaving incorrectly
while searching for an empty QByteArray. In this case it
unconditionally returned its second parameter (from). However, from
can be negative, or even exceed the size of this QByteArray. This
patch handles this cases properly.
As a drive-by: this patch adjusts the QByteArray::indexOf(char, qsizetype)
and QByteArray::lastIndexOf(char, qsizetype) overloads to match with the
QByteArrayView implementation. This is done to have similar code paths
in both cases and avoid tricky bugs in future.
Ideally we had to adjust the QByteArrayView implementation, but it's
fully inline, so can't be changed without breaking BC.

There are few slots whose lambdas are empty; most will at least
capture [this]. But there are a few in Qt examples that do, e.g. []{
qApp->quit(); }. Logging is also an example. So go the extra mile and
optimize for empty functors by inheriting from them as opposed to
storing them in a member variable.

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.

C++20 deprecated compound volatile statements such as pre- and
post-increments, to stress that they're not atomic. So instead of
volatile i;
~~~~;
++i;
you're now supposed to write
volatile i;
~~~~;
int j = i; // volatile load
++j;
i = j; // volatile store
which matches more closely what hardware does.
Instead of fixing every use of volatile pre- or post-increment in this
fashion individually, and realising that probably a few more Qt
modules will have the same kind of code patterns in them, write
QtPrivate functions to do the job centrally.

Before this change, next() was the only way to advance the iterator,
whether the caller was ultimately interested in just the filePath()
(good) or not (bad luck, had to call .fileInfo()).
Add a new function, nextFileInfo(), with returns fileInfo() instead.
Incidentally, the returned object has already been constructed as part
of advance()ing the iterator, so the new function is faster than
next() even if the result is ignored, because we're not calculating a
QString result the caller may not be interested in.
Use the new function around the code.
Fix a couple of cases of next(); fileInfo().filePath() (just use
next()'s return value) as a drive-by.
[ChangeLog][QtCore][QDirIterator] Added nextFileInfo(), which is like
next(), but returns fileInfo() instead of filePath().

We missed the chance of deprecating them in 5.15, so
they'll just add to the pain of porting to 6.0. We
should not keep them around forever, though; QMap isn't
random access and so its iterators should only have
bidirectional APIs.
