Marc Mutz 0808beace3 QBitArray: fix potential truncation in QDataStream op>>()
In Qt 5, a QBitArray could not contain more than INT_MAX bits, because
the then-size_type, int, cannot represent more, even if the underlying
storage could hold 8x as much, and the serialisation format, using
unsigned int, could represent 2x.

Therefore, reject old formats with sizes that exceed INT_MAX elements
as corrupt.

Likewise, the Qt 6 serialisation format unconditionally uses 64-bit
sizes, but 32-bit platforms still cannot represent more than
numeric_limits<qsizetype>::max() (= INT_MAX) bits in memory. This is a
valid stream for 64-bit platforms, though, so ideally, this should be
using SizeLimitsExeeded, which, however, is only available from Qt
6.7. So, for now, and until we have SizeLimitsExeeded, mark the stream
as corrupt here, too.

[ChangeLog][QtCore][QBitArray] Fixed undetected overflows in the
deserialisation (opertor>>()) from QDataStream.

Marc Mutz c6aa399d06 QBitArray: avoid overflow in size-to-storage calculations
Unlike other containers, a QBitArray's size() is not limited by
storage, but, esp. on 32-bit platforms, its size_type: A INT_MAX
size() QBitArray only requires 256MiB of storage.

So we can't rely on "won't happen in practice" here and need to avoid
the potential UB (signed overflow) in the (size + 7) / 8
logical-to-storage-size calculation by using unsigned arithmetic.

Use the opportunity to Extract Methods storage_size() and
allocation_size(), which differ by one (d[[0] contains the size() mod
8), making it clear what's what.

[ChangeLog][QtCore][QBitArray] Fixed a bug with QBitArrays whose
size() came within 7 of the size_type's maximum.

Edward Welbourne 4fe7e8e51a Rework tst_QLocale::ctor() - split up and make data-driven
There were three things going on in this test (itself a sufficient
reason to split it up):
* Some reporting and checking of the default locale; the reporting is
  duplicated in defaulted_ctor() and the check fitted more naturally
  there.
* Checks that various combinations of language, script and territory
  got resolved according to likely-subtag rules. These were handled
  via a macro and natural candidates to become data-driven.
* A test that territory is preserved when it's the only given tag
  (with a few known exceptions); broken out as a steparate test.

In the process, give the data-rows of the likely-subtag parts names
that let me extend their testing to also test construction from
string. The territory-only cases can't support that, as QLocale
doesn't support und_* forms of tags for unspecified language.

Fabian Kosmale ac001bef79 moc/QMetaProperty: Remove limitation on non-own-class notify signals
The moc generated code does a sanity check that NOTIFY signals actually
exist in the parent class when they cannot be found in the class moc
currently runs on.
The logic there was however too simplistic, and couldn't deal with
signals taking a parameter.
Fix this, and take the opportunity to use a proper static_assert instead
of generating a "normal" compile error.

We do not do any checks for the presence of QPrivateSignal, as the whole
point of QPrivateSignal is that it should be private (and not e.g.
protected).

Moreover, we adjust QMetaProperty::notifySignalIndex to take
single-argument notify methods into consideration as well when
encontering an unresolved notify index.

Tinja Paavoseppä 06d2aa91eb Android: Add a context delegate for embedding QML to native Android
When we are embedding a QML view to a non-Qt Android app, there are a lot
of functionalities that are shared with the refular Qt Android app, but
some are not. We should not, for example, try to control the hosting
Activity.
Create a base class that both the QtActivityDelegate, used for the
standard Qt for Android app, and the delegate for the embedding case
can extend.

In this commit, the QtEmbeddedDelegate is very simple, the
biggest difference to QtActivityDelegate being it does not create
a QtLayout or instantiate a QtAccessibilityDelegate.
It does start the Qt app, without waiting for a layout, and register
to listen for changes in the state of the Qt app.

Taking the embedded delegate into use, loading the embedded QML
views and their handling is added in a follow up commit.

Thiago Macieira f5021835df qTo*ViewIgnoringNull: further ignore nulls
Commit ba5db13c8d ("QStringView: add
internal qToStringViewIgnoringNull()") said:

  As long as a null QString still returns non-null data(), QStringView's
  QString constructor needs to call isNull(). That's a branch we often
  can do without, so add an internal function that bypasses this
  correctness check.

  It's internal, since we might have a Q6String that returns nullptr
  data() when null, which will remove the need for this function.

For Qt 6, we made QString and QByteArray be able to return nullptr from
data() when null... but that's not enabled by default yet. However, the
begin() functions do return nullptr, so we can avoid the extra branch
the commit was talking about.

Ahmad Samir 675b4f63fe QIdentityProxyModel: add setHandleSourceLayoutChanges(bool)

(abbreviated as SMLC from here on out), they relied on disconnecting the
connections to the _q_*layout* slots in the private class using the SLOT

were renamed to remove _q_ prefix).

Sub-classes resorting to using private API is a clear sign some
functionality is missing from the public API, so a cleaner solution for
this issue is adding this setter which enables sub-classes to tell
QIdentityProxyModel to leave handling of the SMLC to them. Thanks to

Because we may be able to use the other side's storage and apply the

small so there's a good chance it's just to the extra space QArrayData

Disassembly with GCC 13 and Clang 17 show the vectorisers did kick in

Arno Rehn 59e21a536f QFuture: Don't use QFutureCallOutInterface for continuations
This patch replaces the QBasicFutureWatcher that was used for
continuations with context objects with a smaller QObject-based wrapper
that works directly from the actual continuation.
The idea stays the same: In order to run continuations in the thread of
a context object, we offload the continuation invocation to the
signal-slot mechanism.
Previously, we've hooked into QFuture with QFutureCallOutInterface to
emit a signal and trigger continuation invocation. However, it is much
easier and robust to emit that signal from the continuation itself.

This sidesteps the locking issues that QFutureCallOutInterface handling
presents. QFutureCallOutInterface basically requires any consumer to
only access the QFuture after all events have been posted and the
internal mutex unlocked, i.e. on the next cycle of the event loop.

Continuations do not impose this restriction; runContinuation()
explicitly unlocks the internal mutex before calling the continuation.

This fixes a deadlock when using QFuture::then(context, ...) where
the paren future is resolved from the same thread that the context
object lives in.

Replace the ad-hoc implementation of QTest::toString() in

Since the ABI issues revolving around the new int128 types are not
known, yet, avoid baking the types into the ABI by a) making the
operators constrained templates¹ and b) passing though void* to the
exported helpers. These functions return an error message if Qt was
compiled without support for int128.

Use the Thiago Trick™ (leaving obviouly dead code around for the
compiler to remove without warning) to expose more code to more
compilers. This appears to work elsewhere in Qt, so I hope it does
here, too.

This completes the minimum qint128 support so we're able to debug code
and write tests that use these types.

¹ Templates, unlike inline member functions of wholly-exported
  classes, never² become part of the ABI.

Fix it by explicitly introducing comparison operators for other integral

Use the new compare helper macros for that, and implement helper methods

Note that we have to manually extend the std::is_integral type trait

The twentieth century is now some way behind us, so using its years
when parsing a date-time format that only provides the last two digits

indicates the first of 100 consecutive years, among which the two
digits given can select a year. Add some test-cases to exercise the

Ivan Solovev 3d231e27a8 Long live qCompareThreeWay()
qCompareThreeWay() is a top-level wrapper around the helper
three-way comparison methods, which is mostly convenient for
generic client code.

When implementing compareThreeWay() for Qt types, we normally
provide the implementation only for (LeftType, RightType) pair,
but not the reversed one.
However, it is expected that qCompareThreeWay() would be available
for both combinations, because the reversed result can be easily
calculated.
Solve it by providing a helper hasCompareThreeWay<LT, RT> variable
and branching the implementation based on its value.

The noexcept check is inspired by the old implementation of qSwap().

[ChangeLog][QtCore] Added qCompareThreeWay() as a public API for
three-way comparison.

Marc Mutz 7f5b795f75 QSpan: ensure interoperability with std::span
We accepted QSpan as a NIH-type instead of waiting for C++20 and
std::span, because we said that there's no impedance mismatch between
the two, as they both implicitly convert into each other.

But we actually never checked that they do.

Fix this omission by adding constructors that treat std::span exactly
the same as QSpan itself, and adding the respective static_assert()s
to tst_QSpan to check that (within the constraints imposed by the
standard on std::span), they actually do convert into each other.

The only two problematic cases are that fixed-size std::span
constructors are explicit, so span is only constructible, not
convertible, from QSpan. Likewise, for an rvalue QSpan to be
acceptable to the std::span constructor, QSpan needs to opt-in to
enable_borrowed_range (while we're at it, do enable_view, too).

We so far have rejected adding these opt-ins for our own container
classes because we wanted to avoid the compile-time overhead of
including the huge <ranges> header into such central headers as those
that define our containers.

But std::span itself has to specialize these traits, and its range
contructor has to use them, so they must be available from <span>,
too, possibly the stdlib puts the definition into a much smaller
header. So just assume we can specialize it after including just
<span>, provided __cpp_lib_concepts is also defined.

Ivan Solovev 96f494bf92 Implement helper Qt::compareThreeWay() function for built-in types

For built-in types we provide the implementation inside the Qt

We have to use custom IsIntegralType trait because libstdc++ only
treats __{u}int128_t types as integral when compiling in -std=gnu++XX
mode, and we compile Qt in -std=c++XX mode.

This patch provides the implementations only for compareThreeWay()
overloads, because there is no need to implement comparesEqual() for
built-in types. It would just be equivalent to calling operator==(),
so the user can do it directly.

Ivan Solovev fe12650e9d Implement compare helper macros
These macros should unwrap into a proper set of equality and ordering
operators, depending on the C++ standard being used.
For C++17, all 6 operators (==, !=, <, >, <=, >=) are overloaded, while
for C++20 only the overloads for opeartor==() and operator<=>() are
provided.

The macros are documented as internal for now.

The macros rely on two helper functions:
  bool comparesEqual(LeftType lhs, RightType rhs);
  ReturnType compareThreeWay(LeftType lhs, RightType rhs);

The comparesEqual() helper function is used to implement operator==()
and operator!=().
The compareThreeWay() helper function is used to implement the four
relational operators in C++17, or operator<=>() in C++20.
ReturnType must be one of Qt::{partial,weak,strong}_ordering.
When possible, the functions should also be declared constexpr and
noexcept.
It's the user's responsibility to provide the functions before
using the macros.

Implement a test case which applies the new macros to the dummy
classes, and uses the new helper function to verify the comparison
results.

The MSVC compiler before version 19.36 has a bug, where it fails
to correctly generate reverse opeerators in C++20 mode. Introduce
a new Q_COMPILER_LACKS_THREE_WAY_COMPARE_SYMMETRY definition for such
compiler versions, and use it to manually generate reversed
operators when needed.

Marc Mutz bdd41f491c Rename Q*Ordering to Qt::*_ordering
Since we cannot re-use the pre-existing QPartialOrdering type due to
binary-compatibility issues (it's not BC to std::partial_ordering),
we're no longer bound to copy its API for consistency.

So copy std::*_ordering type API for consistency instead, to ease
porting for users that can already use C++20 and everyone else come
Qt 7.

This patch is another step in that direction, renaming classes and
their memmbers to std-compatible names. QPartialOrdering cannot
change, as it's pre-existing. So add a completely new type
Qt::partial_ordering.

Adding conversions from QPartialOrdering is left for a follow-up
patch.

As a drive-by, change `\c Less` to `\l Less` in the \class
documentation blocks of the new classes.

std::is_eq etc work fine on our Q*Ordering types when C++20 is
available. But in C++17 mode, they're absent.

Plug the hole by providing them for our own types as hidden friends,
so that users can use unqualified calls to transparently support both
std::*ordering and Q*Ordering types, just like with comparison to
literal zero.

For some reason, we running here into

Bionic only for NDK version 19 in 2019.

So we could merge the Android code to the POSIX version, but it's easier
to merge the non-Android code to the raw system call.

Jøger Hansegård 8d367dec15 Add QUniqueHandle - a general purpose RAII wrapper for non-memory types
When interfacing with C-style APIs, such as the Windows API, resources
are often represented using handle objects. Lifetime management of such
resources can be cumbersome and error prone, because typical handle
objects (ints) do not give any help to release resources, and to manage
ownership.

Although std::unique_ptr can be retro-fitted with a custom deleter, and
helps transfer of ownership, it is inherently a pointer type. It can
therefore be clumsy to use with C-style APIs, particularly if the
invalid (uninitialized) handle value is not a nullptr. Also, the
std::unique_ptr does not work well when an allocating function returns
the handle as a pointer argument.

The QUniqueHandle addresses these issues by providing a movable only
value type that is designed as a RAII handle wrapper.

A similar handle wrapper exists in the Windows SDK, as part of the WRL
library. Unfortunately, this is Microsoft specific, and is not supported
by MINGW.

Since the QUniqueHandle is platform independent, it can be used also
with non- Microsoft platforms, and can be useful with other C-style APIs
such as FFmpeg or SQLite.

Since GCC 8 and 9 are slowly fading away as supported compilers, the
simplest fix to get a clean build is to suppress all warnings for the
test on these compilers, by passing -w, as suggested by
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90449.

Short of moving the affected code into a separate header file and
applying `#pragma GCC system_header` to it, there appears to be no
other way to get rid of the warning.

or Service counterpart.

The QtServiceDelegate is used no where and have no special

Ivan Solovev e85a3cde2f QSharedMemory: fix attach() -> create() for non-legacy SystemV mode
The problem with non-legacy mode is that the backend uses the same
filename for the system semaphore file and for the shared memory file.

What happens is that when we try to call attach(), a semaphore is
created. Later in attach() we set unix_key, because ftok() returns
a valid handle (it uses the file which was created for semaphore).
After that, an attempt to actually attach to a shared memory fails, but
no clean-up is done.
So, a later call to create() sees that unix_key is already valid, but
it cannot properly clean it, because it does not actually refer to
any shared memory.

Fix it by cleaning up unix_key and nativeKeyFile if shmget() call in
attach() fails.

all bindable properties.

The original code from tst_QObject can now be removed.

The patch effectively reverts f791570b86
because a lambda returning a nullptr now means that the binding loop
test should be skipped, which is not a good default behavior.

Mårten Nordheim d8d5922f16 QLocal8Bit::convertFromUnicode[win]: handle trailing high surrogate
The win32 API doesn't give us much choice. _Some_ code pages have
support for returning some error if we pass a specific flag, but not
all of them.

Anyway, since the code pages might not support all that UTF-16 provides,
we can't reasonably make it error out on characters that cannot be
converted.

So, the most reasonable thing we can handle is a unpaired high surrogate
at the end of a string, assume that the rest of the string was fine, and
that the low surrogate will be provided in the next call.

Ivan Solovev c4f7dba81e QDate: make conversion from/to chrono types constexpr and noexcept
Add method stdSysDaysToJulianDay(), which implements the conversion
from std::chrono::sys_days to Julian Day in a constexpr and noexcept
manner. Use it in the fromStdSysDays() method instead of addDays(),
and also in all constructors from std::chrono types.
This allows all constructors to be constexpr and noexcept.

Simplify toStdSysDays() so that it could also be constexpr and
noexcept.

Add compile-time roundtrip tests between QDate and std::chrono types.

Edward Welbourne 4389b0c429 Report as available every QTimeZone(qint32).id() result
The QTimeZone(id) constructor accepts these IDs, but
isTimeZoneIdAvailable() did not admit to this. Although we cannot
sensibly list all 183,047 of them in availableTimeZoneIds(), we should
not claim they are unavailable. The custom QTZ constructor needs to
know when the ID it's been given is an IANA one (to refuse to use it),
so it has to be able ask the backends for "is this IANA", so the UTC
backend still has to report these IDs as invalid, leaving the QDT
frontend to include the check for these offset zones.

Extend isTimeZoneIdAvailable() test to include every offset-zone's ID
within QTZ's recognized range of offsets. Although the actual range
accepted by offsetFromUtcString() is wider, bounded by ±24:59:59, the
constructor from offset seconds (rather than offset string) is bounded
by ±16 hours.

Edward Welbourne 58fd829cdf Use localized time-zone abbreviations or offset
The actual formatting of date-time strings is handled by the calendar
backend, but the code's in qlocale.cpp as it uses some of its tools.
When feature timezone is unavailable, we're stuck (as before) with
using QDateTime::timeZoneAbbreviation(), but when it's available we
can use QTimeZone::displayName() to get the localized form of the
abbreviation and offset string.

Make matching changes in QDTP so that it recognizes these localized
abbreviations. We now have another candidate for what local time might
be called, to add to those that must be checked.

This naturally implied some changes to tests. It turns out ICU
believes en_US uses GMT+1/GMT+2 for CET/CEST. Replace some MS
QEXPECT_FAIL()s by including the non-abbreviations we do in fact use
on MS in the lists of "abbreviations" to accept.

[ChangeLog][QtCore][QLocale] When a datetime format includes the
timezone (or offset), the appropriately localised form is (to the
extent the timezone backend in use supports this) used where,
previously, a haphazard choice of system and C locale was used. This
applies to both serialization and parsing.

Thiago Macieira 935562a77b QTemporaryFile(Name): don't make the path absolute on generation
I need to use QTemporaryFileName in a context where absolute paths are
not allowed because they change the behavior of the system call (the
-at() POSIX system calls); see next commit. This required a fix to a
seemingly unrelated test, which depended on the absolute path, because
QPluginLoader and QLibrary assume a file name with no path components
imply "search the standard places".

[ChangeLog][Important Behavior Changes][QTemporaryFile] This class will
now return relative file paths in fileName() if the file template was
also a relative path (it used to always return an absolute path). The
temporary files are still created in the same directory; this change
only affects the length of the path the function returns.

Edward Welbourne 1e74f67e54 Work round ICU disagreeing with TZDB about zone transitions
Since the TZ backend resorts to ICU for display names, we got
inconsistent results if they disagree about when transitions happened.
Also, ICU uses the current (or only recent history) names for the
zone, so one currently not doing DST (Africa/Tripoli) doesn't get a
report of its DST name at a historical time when it did DST (but ICU
doesn't know about it). Since the ICU backend, in any case, doesn't
override the displayName(qint64, ...), we can simply use the QTZP base
version instead of overloading in the TZ back-end, so we only delegate
to ICU when it might actually help. This also saves duplicating some
locking and lazy-initialization code.

In the process, turn a unique lock into a scoped lock within a
suitable scope. Also, make a comment more grammatical and less
verbose.

Giuseppe D'Angelo 358745d7de QSP/QWP: introduce owner_before, owner_equal, owner_hash
While at the moment we don't have aliasing support in QSharedPointer,
introduce owner-based comparisons and hashing. This also fulfills some
use cases in lieu of operator== for QWeakPointer (which got deprecated
by bb23a05905).

I'm using C++26/P1901's spelling of owner_equal, instead of
Boost.SmartPtr's spelling (owner_equal*s*). Given the niche use case,
the lack of interoperability with Qt's own containers, as well as the
Standard comparison objects' semantics (std::owner_less,
std::owner_equal), I don't think we should be giving these a Qt-ish name
as it would be pretty useless.

[ChangeLog][QtCore][QSharedPointer] Added owner_before, owner_equal,
owner_hash.
[ChangeLog][QtCore][QWeakPointer] Added owner_before, owner_equal,
owner_hash.

Piotr Wierciński 4f168621d2 wasm: Fix test runner for asynchronous tests
Test runner was not properly handling tests which
return the control back to browser event loop.
It was treating such tests as if they exited with
code 0, marking them as succesfull even if they were
eventually failing or hanging.
This commit adds a callback to TestCase so the runner
is notified when a test truly has finished.
As a side effect, two tests need to be disabled for now
as they are failing for wasm, which was not properly
detected previously.
