bac329a28b QRegularExpressionMatch: add a way to know if a capturing group captured
Relying on the fact that a given capturing group captured a null string
doesn't allow users to distinguish whether a capturing group did not
capture anything, or captured a null substring (say, from a null subject
string).

Perl allows for the distinction: the entries in the @- and @+ arrays are
set to values in case there is a capture, but they're undef otherwise.

PCRE2 gives us the information already in the results "ovector", but
it was simply not exposed to QREM users. So, expose it.

[ChangeLog][QtCore][QRegularExpressionMatch] Added the hasCaptured()
family of functions to know if a given capturing group has captured
something.

An oversight in the code kept the algorithm in the GB11 state, even if
the codepoint that is being processed wouldn't allow for that (for
instance a sequence of ExtPic, Ext and Any).

Refactor the code of GB11/GB12/GB13 to deal with code points that break
the sequences (falling back to "normal" handling).

Add some manual tests; interestingly enough, the failing cases are not
covered by Unicode's tests, as we now pass the entire test suite.

This re-adds some tests for it, and reimplements the unlinking

It ignores the special handling for QPropertyAlias, so that we can skip
the tag check. It is only used in QPropertyObserverNodeProtector and
clearDependencyObservers, where we already know the type of the

70df6052d8 tst_QPluginLoader: Simplify creating a fake pointer in fakeplugin.cpp
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'
    QT_PLUGIN_METADATA_SECTION const char message[] = "QTMETADATA";
                                          ^
    fakeplugin.cpp:32:40: note: declared here
    QT_PLUGIN_METADATA_SECTION void *const pluginSection = (void*)(0xc0ffeec0ffeeL);
                                           ^

See https://bugs.llvm.org/show_bug.cgi?id=51442 for discussion
on the matter in Clang.

To simplify things, just initialize the fake pointers as regular
uintptr_t instead, avoiding the whole matter. This produces the
exact same contents in the section as before.

For what it's worth, the actual manually constructed metadata in
fakeplugin.cpp doesn't seem to have any effect on running the
QPluginLoader tests on either ELF or MachO right now.

11d1dcc6e2 QString: use the QRegularExpression operations on QStringView
There's no need of duplicating code all over the place; QString can
reuse the implementation of the indexOf/contains/count/lastIndexOf
family of functions already existing for QStringView.

For simplicity, the warning messages (that our autotests actually check)
have been made more generic, rather than introducing some other
parameter (as in, "which class is using this functionality so to emit
a more precise warning"), which would have just complicated things as
the implementation of these functions is exported and used by inline
QStringView member functions.

f0d1f50e02 QRegularExpression: fix matching over null/empty QString(View)
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)).

6cee204d56 QS(V)/QBA(V)/QL1S::lastIndexOf: fix the offset calculations
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.

bef57b317f testlib: Deprecate QWARN() in favor of qWarning()
The QtTest best practices documentations recommends using output
mechanisms such as qDebug() and qWarning() for diagnostic messages,
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
on file and line number information in release mode, but QWARN() will.
This is an acceptable loss of functionality, considering that the user
can override this behavior by defining QT_MESSAGELOGCONTEXT.

[ChangeLog][QtTest] QWARN() has been deprecated in favor of qWarning()

e150bcfe4d QByteArray: fix indexOf/lastIndexOf
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.

3a72496b5c tests: fix some -Wvolatile
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.

25fff849e8 QDirIterator: add nextFileInfo()
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().

b095d26878 QHash/QSet: fix squeeze() for default-constructed container
QHash::squeeze() was unconditionally calling reserve(0), which is
always allocating memory (even for 0 size).
This was leading to a confusing situation when calling squeeze() on
a default-constructed container with 0 capacity() actually allocated
memory. This is very misleading, as squeeze() is supposed to free
unneeded memory, not to allocate more.

This patch adds a check for non-zero capacity. As a result, nothing
is done for default-constructed container.

When inserting items into the result store, a ResultItem is created,
which stores a pointer to the results list and their size. If the size
of the ResultItem is set to 0, it means that a single result is stored.
In case of trying to report results via an empty list, the size is 0, so
result store treats it as a single result.

Added checks before storing the results to make sure that the result
list isn't empty. Note that empty lists are allowed in some cases for
the filter mode, because ResultStoreBase::addResults() knows how to
handle those cases correctly.

0c2125458a Consistent handling of disabled items in QItemSelectionModel
In QItemSelectionModel, items which are disabled or marked as not
selectable should not be considered as selected. But this was
not handled consistently.
The following methods considered only items which are enabled and
marked selectable: selectedIndexes(), rowIntersectsSelection(), and
columnIntersectsSelection(). The following methods considered only
items which are marked selectable, but did not check whether they
are enabled: selectedRows(), selectedColumns(), isRowSelected(),
isColumnSelected(), isSelected(). Finally there is hasSelection(),
which did not check for enabled nor for selectable.
This patch introduces consistent behavior. All methods check
both whether the items are enabled and whether they are selectable now.

[ChangeLog][QtCore][QItemSelectionModel][Important Behavior Changes]
All methods in QItemSelectionModel now consider only items which
are marked as enabled and selectable as part of the selection.

27d6314b95 QCryptographicHash: use a std::array to hold result (was: QByteArray)
The maximum size for a hash result is 64 atm. Even if, and esp when,
we'll get to 128 and 256 bytes in the future, there's no reason to use
dynamic memory, because the sizes will always be statically known.

So use, essentially, a std::array<char, 64> to hold the result
internally. Add a bit of convenience API on top to limit impact on the
rest of the code and add a few static_asserts that ensure this is large
enough. Then give users access to the internal buffer by adding
QByteArrayView resultView() const noexcept. The documentation snippet
is taken from QString::data(), suitably adjusted.

Use resultView() in a few places instead of result().

[ChangeLog][QtCore][QCryptographicHash] Changed to use a
statically-sized buffer internally. Added resultView() to access it.

a clearer error, at the call site:

    QT_DECLARE_NATIVE_INTERFACE_ACCESSOR(QGuiApplication)
    ^
By using SFINAE for the TypeInfo we can also ensure that it works for
types that are not native interfaces, such as if the user tries to
call nativeInterface<QString>().

Since we can no longer use decltype(*this) to resolve the base type
we need to change QT_DECLARE_NATIVE_INTERFACE_ACCESSOR to take the
type as an argument, as we do for other QT_DECLARE_FOO macros.

2b50c8bec0 QObject: optimize the common case of findChildren(QString())
Outside tests, all in-tree callers of QObject::findChildren() pass no
name to match, and in my experience that is also true for the vast
majority of out-of-tree users.

Avoid the temporary QString creation in the caller and the repeated
QString::isNull() checks in the implementation by overloading
findChildren() without a name argument and checking for name.isNull()
only once, forking off into separate helper functions.

Adjust in-tree callers that used an explicit `QString()` argument in
order to pass options, which goes to show that `name` should never
have been the first argument of findChilden() in the first place, even
though I appreciate the symmetry with findChild() (the use-cases of
which, however, are radically different).

Change a `findChildren().size() == 0` call found while scanning for
findChildren() calls to `!findChild()` as a drive-by.

Modernize loops in the various qt_qFindChild{,ren}_helper() overloads
to match how the new code looks.

[ChangeLog][QtCore][QObject] Added findChildren() overload taking no
name (thus optimizing this common case).

3eac6079d9 macOS: Don't mangle QByteArray settings with @ prefix by decoding as UTF-8
QSettings encodes QVariants as @Type(data) strings. If that data contains
a null-byte, we write the string as UTF-8 encoded CFData. When reading it
back we look for a @ prefix, and then pass it as UTF-8 through stringToVariant.

The problem arises then the user writes raw QByteArrays with a @ prefix.
We can detect this situation by checking the result of stringToVariant,
and if it's just a simple conversion of the string into a QVariant, we
know that stringToVariant hit its fallback path due to not finding any
embedded variants.

If that's the case, we return the raw bytes as a QByteArray.

cc64959602 Tidy up tst_QString::localeAwareCompare()
It was suppressed unconditionally (albeit in different places and with
different levels of obviousness) almost everywhere, due to inability
to set the system locale in use by the implementation. Several
test-cases used ISO-8859-1 encoding on Q_OS_MAC, where the tests were
all suppressed anyway. A block of no_NO tests was #if 0'd out; and
should, in any case, have been nb_NO. Tests of any locale but en_US
were skipped on Q_OS_WIN because we can't set the locale (but
including the tests of en_US tacitly assumed that's the system
locale). If setlocale() failed, for ICU or DARWIN, the test was
skipped; but we might as well check for this in the _data() to save
repetition.

The test was laboriously going through the sign cases; relocate the
QString::compare() test's sign() function so that we can use it here,
too, and simply QCOMPARE() signs. Introduce a TransientLocale class,
copied from tst_QLocale, to take care of setting and restoring the
locale using setlocale(). Change the locale name to a QByteArray so
that we save having to convert it to one in order to pass it to
setlocale(). Since that changed every _data() row, reformat those rows
in the process - most of them were long lines.

On the systems where we can't set the locale used by the function
being tested, condition each block of tests in the _data() on whether
LC_COLLATE looks like the locale to be tested, and report how a
determined developer at least can (by repeatedly running the test with
different locales set) test all the cases; and we'll attempt the ones
that we can, when one of the relevant locales is in use. If that
leaves us with no tests we can do, QSKIP() in the _data() to avoid an
assert failure for "Test data requested, but no testdata available."

9661cde161 Apple: Use POSIX IPC instead of System V in sandboxed applications
System V semaphores are not supported in sandboxed applications,
so when Qt is configured with App Store compliance, or the user
requests POSIX IPC explicitly, we use that instead.

https://developer.apple.com/library/archive/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html#//apple_ref/doc/uid/TP40011183-CH3-SW24

As the shared memory name limit on Apple platforms is very low,
we have to skip the existing logic for naming, and instead use
a truncated hash of the key. This should still be fine for
avoiding any collisions in practice.

An explicit check for the ENAMETOOLONG error has been added to
catch any cases where they key goes beyond the allowed length.

Sandboxed applications also have an extra requirement that the
key must include an application group identifier. This requirement
has been pushed up to the user and documented, as we don't have
enough information in Qt to know which identifier to use.

Both tst_QSystemSemaphore and tst_QSharedMemory work as before
with both sandboxed and non-sandboxed applications, after removing
some assumptions in tst_QSharedMemory about System V behavior.

Fixes: QTBUG-91130
