QLibrary intentionally does not unload on destruction, so failing tests
may leave libraries already loaded and cause further tests to fail
because of that. So add a cleanup() method to unload everything we may
have loaded.
Note that QLibrary::unload() sets its state to NotLoaded after one
successful call, so we must recreate the object in case it had been
load()ed multiple times.

The "qhash" test relied on the fact that those four elements would
produce a different order with a zero and a non-zero seed. But since
commit b057e32dc4 removed the setting of a
deterministic non-zero seed, this test had a 1 in 4! chance of failing.
Since 4! = 24, 128 retries should be more than enough to ensure we do
find at least hash seed that provokes a different order.

The zlib convenience API we've been using so far has two problems:
- On Windows-64, where sizeof(long) == 4, the use of ulong for sizes
meant that we could not compress data compressable on other 64-bit
platforms (Unix). While zstream also uses ulong, being a stream API,
it allows feeding data in chunks. The total_in and total_out members
are only required for gzip compression and are otherwise just
informational. They're unsigned, so their overflow does not cause
UB. In summary, using zstream + deflate() allows us to compress more
than 4GiB of data even on Windows-64.
- On all platforms, we always allocated the output buffer in such a
way as to accommodate the pathological case of random, incompressible
data, so the output buffer was larger than the input. Using zstream
+ deflate(), we can start with a smaller buffer, then let zlib pick
up where it left off when it ran out of output buffer space, saving
memory in the common case that compression meaningfully reduces the
size. To avoid the first few rounds of reallocations, we continue to
use zlib's compressBound() for input less than 256KiB.
This completely fixes the compression side of QTBUG-106542 and

The zlib convenience API we've been using so far has two problems:
- On Windows-64, where sizeof(long) == 4, the use of ulong for sizes

it allows feeding data in chunks. The total_in and total_out members
are only required for gzip compression and are otherwise just

more than 4GiB of data even on Windows-64.
- On all platforms, if the size hint in the header was too short, we'd
double the output buffer size and try again, from scratch. Using
zstream + inflate(), we still need to reallocate, but we can then
let zlib pick up where it left off when it ran out of output buffer
space. In all but the most pathological cases, copying the
already-decoded data instead of re-decoding it again should be
faster, esp. if QArrayData uses realloc() instead of malloc() +
free() to grow the buffer.
We also now directly allocate at least as much output buffer as we
have input, to cut the first few rounds of reallocations when the
expectedSize was created, as qCompress still does, using modulo
arithmetic mod 4GiB instead of saturation arithmethic.
Factor the growing of the output buffer into a wrapper function,
flate(), which can be reused when porting qCompress().

This is a combination of Q_UNREACHABLE() with a return statement.
ATM, the return statement is unconditionally included. If we notice
that some compilers warn about return after __builtin_unreachable(),
then we can map Q_UNREACHABLE_RETURN(...) to Q_UNREACHABLE() without
having to touch all the code that uses explicit Q_UNREACHABLE() +
return.
The fact that Boost has BOOST_UNREACHABLE_RETURN() indicates that
there are compilers that complain about a lack of return after
Q_UNREACHABLE (we know that MSVC, ICC, and GHS are among them), as
well as compilers that complained about a return being present
(Coverity). Take this opportunity to properly adapt to Coverity, by
leaving out the return statement on this compiler.
Apply the macro around the code base, using a clang-tidy transformer
rule:
const std::string unr = "unr", val = "val", ret = "ret";
auto makeUnreachableReturn = cat("Q_UNREACHABLE_RETURN(",
ifBound(val, cat(node(val)), cat("")),
")");
auto ignoringSwitchCases = [](auto stmt) {
return anyOf(stmt, switchCase(subStmt(stmt)));
};
makeRule(
stmt(ignoringSwitchCases(stmt(isExpandedFromMacro("Q_UNREACHABLE")).bind(unr)),
nextStmt(returnStmt(optionally(hasReturnValue(expr().bind(val)))).bind(ret))),
{changeTo(node(unr), cat(makeUnreachableReturn,
";")), // TODO: why is the ; lost w/o this?
changeTo(node(ret), cat(""))},
cat("use ", makeUnreachableReturn))
);
where nextStmt() is copied from some upstream clang-tidy check's
private implementation and subStmt() is a private matcher that gives
access to SwitchCase's SubStmt.
A.k.a. qt-use-unreachable-return.
There were some false positives, suppressed them with NOLINTNEXTLINE.
They're not really false positiives, it's just that Clang sees the
world in one way and if conditonal compilation (#if) differs for other
compilers, Clang doesn't know better. This is an artifact of matching
two consecutive statements.

In theory we don't need the array to be static and it did compile
without any problems so far, indeed. However, with this patch applied,
MSVC complains that the lambda function below can't access the array.
I don't understand why, because we use [&] in the lambda and it should
capture all the variables in theory, but in reality it failed to
capture this variable in the end. And making the variable static
solves this issue. Maybe it's a MSVC bug.

Given the idiomatic usage of {} is indeed to perform a full reset (cf.

Before searching, foldCase the first up to 256 characters, and use this
buffer to compare against the haystack. If the needle is larger than the
buffer, compare the rest of the needle against the rest of the haystack
for every potential match. The buffer is placed on the stack and must be
refolded for each search, but this change does not break the API.
This is faster than the old implementation, except if the needle is long
and it is found near the beginning of the haystack, or if the needle is

To support cancellation of continuations attached via the parent future,
for each future returned by a continuation we store a pointer to its
parent (i.e. future the continuation is attached to). Later, before
executing a continuation, we go through chain of parents and check if
any of them is cancelled. However, if one of the parents is destroyed
while the chain is executing, the next continuations' parent pointers
will become invalid. So storing the parent pointers isn't safe.
This commit changes the logic of handling the cancelled continuation
chain in the following way:
- Instead of storing a parent pointer in the continuation future's data,
we do the opposite: we store a pointer to continuation's future in the
parent.
- When a future is cancelled, we mark all continuation futures in the
chain with a flag indicating that the chain is cancelled.
- To guarantee that the pointers to continuation future's data don't
become invalid, we clean the continuation (that stores a copy of its
future's data and keeps it alive) only when the associated promise
is destructed, instead of cleaning it after the continuation is run.

The collection of translations available to us need not have anything
to do with whether CLDR has matching data, so preserve the system UI
language list's entries as they are, rather than forcing them through
the QLocale constructor's exercise of likely sub-tag rules.
Instead, simply parse the given locale tags to QLocaleId instances and
use these in the likely-subtag processing to determine what other
entries to add to the list in addition to those supplied by the
operating system. Since going via QLocale did usually supply a
territory, that was included in the BCP 47 name, it's now possible for
the given entry to lack the language_territory name, so be sure to add
that if missing.
This incidentally reduces heap traffic and saves a fair deal of hidden
likely-subtag processing in calls to the constructor and bcp47Name().
Expand testing of QLocale::uiLanguages(), both plain and system. In
the process, cross-link the two closely-related tests, move a comment
on one's _data() to the other's, where it really belongs, and add
reporting of the actual lists on failure. Enable MySystemLocale to
remember the requested locale's ID, before likely sub-tag processing,
so that we can make query() report results for language, script and
territory as requested, to ensure the fake system locale really does
match what was requested. The new german-britain test failed without
it, because there is no de-GB locale in CLDR.

When the system locale is en_DE, macOS seems to think we should use

choice in the absence of an en_DE translation, we should definitely
use the en_DE translation if available, especially if en_GB isn't
available (which lead to a fall-back to de_DE, given later entries in
macOS's list). So prepend the system locale's own pcp47Name() if it
(isn't the C locale and) is missing from what we would otherwise have
used for uiLanguages(), after likely sub-tag perturbations.

ownMethodIndex works for all kind of methods, also for constructors.
Therefore, remove the assertion there (that checks for non constructors)
and add a test in qtbase so it does not happen again.
The test broken by the assertion is in qtdeclarative:
tst_QJSEngine::newQMetaObject().
Also rename QMetaMethodPrivate::ownConstructorIndex() to
ownConstructorMethodIndex() as the previous naming implied that
ownMethodIndex() could not be used for constructors.

around it. The simplest is to just use variadic macros; another, which

The vast majority of in-tree users pass simple and short C string
literals as the value. By porting to QByteArrayView, we document that
we'll accept non-NUL-terminated data, and do the NUL-termination
internally, using SSO'ed std::string, saving memory allocations in the
common case of short strings.
I didn't bother to check which direction std::string takes for
nullptrs these days (there was a change accepted in that area for

The old code assumed that a QByteArray's data() is always
NUL-terminated. Due to the conflation of owners and non-owners in
QByteArray (but also in case we ever get efficient substringing), this
is not always the case, e.g. QByteArray::fromRawData() does not ensure
NUL-termination.
From QString::utf16(), we learn that the condition to check for is
QArrayData::isMutable(). After working around the fact that
QByteArray::data_ptr() doesn't exist for const QBAs and that empty
QBAs always refer to QByteArray::empty_, which is !isMutable(), we can
detect this situation and re-allocate without introducing new API.
This is the fix for Qt ≤ 6.4. For Qt 6.5, we'll port the function to
QByteArrayView.

Problem description:
--------------------
Assume we have two properties, P1 and P2. Assume further that we assign
a binding to P2, so that it depends on P1. Let the binding additionally
capture some (non-QProperty) boolean, and only create the dependency to
P1 if the boolean is true.
The state afterwards is
P1:[p1vaue|firstObserver]
|
|
v
---[p2binding]
/
P2:[p2value|binding]
If the boolean is set to false, and P1 changes its value, we still
correctly re-evaluate the binding and update P2's value. However, during
binding evaluation we will notice that there is no further dependency
from P2 on P1, and remove its observer.
The state afterwards is
P1:[p1vaue|firstObserver=nullptr]
---[p2binding]
/
P2:[p2value|binding]
Then, during the notify phase, we traverse the observer's again,
starting from P1's firstObserver. Given that it is nullptr now, we never
reach P2's binding, and thus won't send a notification from it.
Fix:
----
We store a list of all visited binding-observers (in a QVarLengthArray,
to avoid allocations as long as possible). After the binding evaluation
phase, we then use that list to send notifications from every binding
that we visited. As we already have a list of all bindings, we no longer
need to recurse on binding-observes during the notification process;
instead, we only need to deal with static callbacks and ChangeHandlers.
The pre-existing notification logic is still kept for the grouped update
case, where we already have a list of all delayed properties, and should
therefore not encounter the same issue. Unifying its codepath with the
existing logic is left as an exercise for a later patch.

QRegularExpression::match (and globalMatch) is currently overloaded
for QString and QStringView. This creates a subtle API asymmetry:
QRegularExpression re;
auto m1 = re.match(getQString()); // OK
auto m2 = re.match(getStdU16String()); // Dangling
This goes against our decision that every time that there's a possible
lifetime issue at play, it should be "evident". Solving the lifetime
issue here is possible, but tricky -- since QRegularExpression
is out-of-line, one needs a type-erased container for the input
string (basically, std::any) to keep it alive and so on.
Instead I went for the simpler solution: deprecate match(QStringView)
and introduce matchView(QStringView) (same for globalMatch). This
makes it clear that the call is matching over a view and therefore
users are supposed to keep the source object alive.
Drive-by, remove the documentation that says that the QString
overloads might not keep the string alive: they do and forever will.
[ChangeLog][QtCore][QRegularExpression] Added the matchView()
and globalMatchView() functions that operate on string views.

This also rewrites QMetaType::id() on top of the helper, with the benefit
of calling a member static function, so QMetaType doesn't need to be
spilled onto the stack. In some upcoming changes I need to ensure that
QMetaTypes are registered so they can be found by name and I'd like to
have a dedicated function name for that, instead of calling .id().
Since I needed to add docs for the new function, I've updated for the
old one too.
[ChangeLog][QMetaType] Added QMetaType::registerType() and an overload
of qRegisterMetaType() taking QMetaType (the two functions do the same
thing). These two functions ensure a given QMetaType is registered with
the Qt global registry, so they can be found by name later. Using
qRegisterMetaType<T>() also accomplishes the same thing, but is slightly
better for completely generic code because it will avoid emitting the
registration for built-in types.
