Marc Mutz f3c340c276 QStringTokenizer::toContainer(): allow more types of target containers
The previous constraint called for the value_type of the container to
exactly match the value_type of the tokenizer, which means
toContainer() could only ever work on containers of views. But there
is value in allowing QStringList, even though it works only on QL1S
needles (QStringView -> QString isn't implicit). But users may have
other types that for better or worse implicitly convert from views, so
we shouldn't over-constrain the function.

[ChangeLog][QtCore][QStringTokenizer] toContainer() now works on
containers whose value_type can be constructed from the tokenizer's
value_type. It no longer requires an exact match.

Eirik Aavitsland f46db29d8c Painting: fix overriding and combining different clip types
In a recent improvement (6de36918c0) the
last set clip region or path was stored in separate variables, in
order to be set again if the aliasing mode changed. That solution was
too simplistic, as it would break down as soon as more than one clip
area was set, with the latter either replacing or intersecting the
first. It was also unnecessary to introduce new storing of clip areas
and transforms, as those are already recorded in the clipInfo stack in
the painter state. This patch hence reverts much of that implementation.

However the basic idea of setting the clip area again after AA change
is good, so that part is kept, implementated instead by calling a
pre-existing function to replay the clipInfo stack.

One of the baseline test cases is extended to excercise the
combination of clip areas. As a driveby, support for setClipRectF is
added to the painting baseline test scripts, and the build of the
manual lance tool is fixed.

Marc Mutz 9da4c6bfb7 QObject: port setObjectName() to QAnyStringView
... while keeping the QString overload for users that pass actual
QStrings (e.g. QStringLiteral).

However, QString and QAnyStringView cannot be overloaded (they're
ambiguous for most arguments), so we need to make one of them a
Q_WEAK_OVERLOAD.

Normally, we'd make the new function weak and keep the old function
as-is, but, here, that would be beside the point, because all callers
would continue to resolve to the QString overload, and nothing would
call the QAnyStringView one.

So we really want the old function to be the Q_WEAK_OVERLOAD, so that
the QString overload is only selected when actual QStrings are
passed. That means we need to leave the old function in a compat build
(compiled in, but not visible in the public header). Since
Q_WEAK_OVERLOADs cannot be (easily) exported (they're templates), make
it call a private function (which can be, and is, exported).

Reviewers may questions whether one can overload

   setObjectName() and
   template <typename = void> setObjectName()

The answer is that we can, because templates mangle differently from
normal functions. We can even call the template function (with
explicit template arguments), as seen in removed_api.cpp.

This adapts the interface of the function to how most users use it:
They pass QLatin1String or just const char[]. Only very few passed
QStringLiteral, which, ignoring that fact that it produces a ton of
code for the temporary QString's destructor that's never executed,
would have been, and continues to be, the optimal way of passing data,
modulo plugin bugs (QTBUG-51602, QTBUG-49061).

[ChangeLog][QtCore][QObject] Added setObjectName() overload taking
QAnyStringView.

Marc Mutz 78073f8ab6 Restore C++20-deprecated mixed-enum bitwise operators
C++20 deprecated arithmetic on enum types. For enums used on QFlags<>,
these operators have always been user-defined, but when the two enums
are of different type, such as QFrame::Shape and QFrame::Shadow, the
deprecation warning pops up.

We have in the past fixed these in our headers by manual casts, but
that doesn't help our users when our API requires them to OR together
enums of different type.

Until we can rework these APIs to use a variadic QFlags type, we need
to fix it in an SC and BC way, which is what this patch sets out to
do.

The idea is simply to mark pairs of enums that are designed to be ORed
together and replace the deprecated built-in bitwise operators with
user-defined ones in C++20. To ensure SC and BC, we pass an explicit
result type and use that to check, in C++17 builds, that it matches
the decltype of the result of the built-in operator.

This patch is the first in a series of similar patches. It introduces
said markup macro and applies it to all enum pairs that create
warnings on (my) Linux GCC 11.3 and Clang 10.0.0 builds. It is
expected that more such markups are needed, for other modules, and for
symmetry.

Even with this patch, there is one mixed-enum warning left, in
qxcbwindow.cpp. This appears to be a genuine bug (cf. QTBUG-101306),
so this patch doesn't mark the enums involved in it as designed to be
used together.

This patch also unearthed that QT_TYPESAFE_FLAGS, possibly
unsurprisingly so, breaks several mixed bitwise flags-enum operations
(QTBUG-101344).

Thiago Macieira 40c8bc4202 qversiontagging: Use C++17 inline variables also on Unix
C++17 inline variables allow us to declare a variable that shall be
merged before linking, which replaces the need for the "comdat" part of
the inline assembly. The GCC attribute "used" tells the compiler not to
discard this variable, like the MinGW case. Additionally, the "retain"
attribute (where supported) tells both the compiler and linker not to
discard, allowing an intermediary, static library to keep this
definition.

This enables support for OSes besides FreeBSD and Linux, where it was
previously available. For example, on macOS:

 $ nm libexec/rcc | grep qt_version_tag
                 U _qt_version_tag_6_4
 00000001000ec608 s _qt_version_tag_6_4_use

On Linux, the assembly output before this change (Clang 13) was:
        .section        .qtversion,"aG",@progbits,qt_version_tag,comdat
        .p2align        3
        .quad   qt_version_tag@GOT
        .long   394240
        .p2align        3

After this change:
        .hidden qt_version_tag_use              # @qt_version_tag_use
        .type   qt_version_tag_use,@object
        .section        .qtversion,"aGwR",@progbits,qt_version_tag_use,comdat
        .weak   qt_version_tag_use
        .p2align        3
qt_version_tag_use:
        .quad   qt_version_tag
        .quad   394240                          # 0x60400
        .size   qt_version_tag_use, 16

The notable changes here are that there is a symbol and that the section
is writable. The latter is required because we store the pointer to the
qt_version_tag variable instead of just an offset in the GOT. The total
number of relocations in the resulting binary remains the same. We've
actually shrunk the binary by one pointer size.

Edward Welbourne 479c95729a Support global data tags in blacklisting identification of test-cases
Previously the blacklisting file format only worked with slot:data or
plain slot names for the items to blacklist. However, tests with
global data report themselves with the global data-row tag in the same
way as function-specific ones do; and tests which have both join the
two as slot(global:data) in the test output name, so the reader is apt
to mistake global:data for a data tag. In any case, it is potentially
desirable to be able to blacklist a function with either or both of
global and local data-row tags specified. Add support for that and
remove a blacklisting that was only needed due to the lack of this
support.

For now, make the new parameter to checkBlackLists() optional, so
that qtdeclarative's qmltest framework can adapt to this change.

Edward Welbourne 08d6bc2477 Prevent exclusion of percent character from percent-encoding
When a percent-replacement present in the exclude list would,
normally, not have been encoded, it was encoded regardless, as
otherwise round-tripping fails. However, when percent or its
replacement would normally have been encoded, its presence in the
exclude list lead to it not being encoded, which duly breaks
round-tripping.  It also violates
https://datatracker.ietf.org/doc/html/rfc3986#section-2.4

[ChangeLog][Incompatible behavior change][QByteArray] When
converting to percent-encoding, it was possible to exclude the percent
character (or its replacement, unless this is one of the characters
not normally encoded) from conversion.  Doing so would violate RFC
3986 Section 2.4 and break round-tripping of any string that contains
the percent character. The percent character, or its replacement, is
now always encoded, even if mentioned in the exclude list, as the
documentation has always claimed.

Laszlo Agocs 68a4c5da9a Compose render-to-texture widgets through QRhi
QPlatformTextureList holds a QRhiTexture instead of GLuint. A
QPlatformBackingStore now optionally can own a QRhi and a
QRhiSwapChain for the associated window.  Non-GL rendering must use
this QRhi everywhere, whereas GL (QOpenGLWidget) can choose to still
rely on resource sharing between contexts. A widget tells that it
wants QRhi and the desired configuration in a new virtual function in
QWidgetPrivate returning a QPlatformBackingStoreRhiConfig. This is
evaluated (among a top-level's all children) upon create() before
creating the repaint manager and the QWidgetWindow.

In QOpenGLWidget what do request is obvious: it will request an
OpenGL-based QRhi. QQuickWidget (or a potential future QRhiWidget)
will be more interesting: it needs to honor the standard Qt Quick
env.vars. and QQuickWindow APIs (or, in whatever way the user
configured the QRhiWidget), and so will set up the config struct
accordingly.

In addition, the rhiconfig and surface type is (re)evaluated when
(re)parenting a widget to a new tlw. If needed, this will now trigger
a destroy - create on the tlw. This should be be safe to do in
setParent. When multiple child widgets report an enabled rhiconfig,
the first one (the first child encountered) wins. So e.g. attempting
to have a QOpenGLWidget and a Vulkan-based QQuickWidget in the same
top-level window will fail one of the widgets (it likely won't
render).

RasterGLSurface is no longer used by widgets. Rather, the appropriate
surface type is chosen.

The rhi support in the backingstore is usable without widgets as well.
To make rhiFlush() functional, one needs to call setRhiConfig() after
creating the QBackingStore. (like QWidget does to top-level windows)

Most of the QT_NO_OPENGL ifdefs are eliminated all over the place.
Everything with QRhi is unconditional code at compile time, except the
actual initialization.

Having to plumb the widget tlw's shareContext (or, now, the QRhi)
through QWindowPrivate is no longer needed.  The old approach does not
scale: to implement composeAndFlush (now rhiFlush) we need more than
just a QRhi object, and this way we no longer pollute everything
starting from the widget level (QWidget's topextra -> QWidgetWindow ->
QWindowPrivate) just to send data around.

The BackingStoreOpenGLSupport interface and the QtGui - QtOpenGL split
is all gone. Instead, there is a QBackingStoreDefaultCompositor in
QtGui which is what the default implementations of composeAndFlush and
toTexture call. (overriding composeAndFlush and co. f.ex. in eglfs
should continue working mostly as-is, apart from adapting to the
texture list changes and getting the native OpenGL texture id out of
the QRhiTexture)

As QQuickWidget is way too complicated to just port as-is, an rhi
manual test (rhiwidget) is introduced as a first step, in ordewr to
exercise a simple, custom render-to-texture widget that does something
using a (not necessarily OpenGL-backed) QRhi and acts as fully
functional QWidget (modeled after QOpenGLWidget). This can also form
the foundation of a potential future QRhiWidget.

It is also possible to force the QRhi-based flushing always,
regardless of the presence of render-to-texture widgets. To exercise
this, set the env.var. QT_WIDGETS_RHI=1. This picks a
platform-specific default, and can be overridden with
QT_WIDGETS_RHI_BACKEND. (in sync with Qt Quick) This can eventually be
extended to query the platform plugin as well to check if the platform
plugin prefers to always do flushes with a 3D API.

QOpenGLWidget should work like before from the user's perspective, while
internally it has to do some things differently to play nice and prevent
regressions with the new rendering architecture. To exercise this
better, the qopenglwidget example gets a new tab-based view (that could
perhaps replace the example's main window later on?). The openglwidget
manual test is made compatible with Qt 6, and gets a counterpart in form
of the dockedopenglwidget manual test, which is a modified version of
the cube example that features dock widgets. This is relevant in
particular because render-to-texture widgets within a QDockWidget has
its own specific quirks, with logic taking this into account, hence
testing is essential.

For existing applications there are two important consequences with
this patch in place:

- Once the rhi-based composition is enabled, it stays active for the
lifetime of the top-level window.

- Dynamically creating and parenting the first render-to-texture
widget to an already created tlw will destroy and recreate the tlw
(and the underlying window). The visible effects of this depend on the
platform.  (e.g. the window may disappear and reappear on some,
whereas with other windowing systems it is not noticeable at all -
this is not really different from similar situtions with reparenting
or when moving windows between screens, so should be acceptable in
practice)

- On iOS raster windows are flushed with Metal (and rhi) from now on
(previously this was through OpenGL by making flush() call
composeAndFlush().

Marc Mutz d743fd0d0a qDecodeDataUrl(): treat ";base64" marker as case-insensitive
RFC2397 doesn't explicitly mention it, but references RFC2045, which,
in Section 2, states:

> All media type values, subtype values, and parameter names as
> defined are case-insensitive.

and goes on, in 6.1:

>   mechanism := "7bit" / "8bit" / "binary" /
>                  "quoted-printable" / "base64" /
>                  ietf-token / x-token
>
>   These values are not case sensitive

So regardless of whether "base64" is a parameter name, or a mechanism,
we need to treat it case-insensitively.

Use QLatin1String::endsWith() instead of QByteArray::endsWith(),
because the former takes Qt::CaseInsensitive while the latter would
need a toLower().

Add a test.

As a drive-by, use the same trick for the existing case-insensitive
comparison with "charset".

As a further drive-by, fix inappropriate uses of QLatin1String (=
where they don't prevent allocations).

[ChangeLog][QtCore][QUrl] Now recognizes the ";base64" marker in
"data:" URLs case-insensitively.

Thiago Macieira 19b7f854a2 Enable -mno-direct-extern-access and ELF protected visibility
The -mno-direct-extern-access tells the compiler and linker that
references to symbols outside this ELF module mustn't be direct and must
instead always go through the GOT or PLT (the PLT can additionally be
disabled with -fno-plt). The ELF protected visibility tells the compiler
and linker that this symbol is present in the dynamic symbol table as an
export, but it cannot be interposed by another ELF module.

This option is required for user code to link properly to Qt, otherwise
they will get linker errors (assuming GNU binutils >= 2.39) or runtime
failures (glibc >= 2.35). Both versions of glibc and binutils are older
than GCC 12, so it's a safe assumption they are in use and downgrading
the toolchain or libc is not supported. Adding this option to the
compilation is assured for CMake and qmake-based projects.

For example, all accessess to QCoreApplication::self in QtCore, after
this change and with GCC 12 are relocation-free and direct:

000000000013ebf0 <QCoreApplicationPrivate::checkInstance(char const*)>:
  13ebf0:       cmpq   $0x0,0x4f73d0(%rip)        # 635fc8 <QCoreApplication::self>
  13ebf8:       setne  %al
  13ebfb:       je     a90fe <QCoreApplicationPrivate::checkInstance(char const*) [clone .cold]>
  13ec01:       ret

Meanwhile, accesses to the same variable in other modules are indirect
via the GOT:

   66650:       mov    0x876e1(%rip),%rax        # edd38 <QCoreApplication::self@Qt_6>
   66657:       cmpq   $0x0,(%rax)

This replaces the -Bsymbolic and -Bsymbolic-functions (broken)
functionality that Qt has been using or attempting to use since ~2006.

Fabian Kosmale ba6c1d2785 QProperty: fix threading issues
QObject's cache the binding status pointer to avoid TLS lookups.
However, when an object is moved to a different thread, we need to
update the cached pointer (as the original thread might stop and thus no
longer exist, and to correctly allow setting up bindings in the object's
thread).
Fix this by also storing the binding status in QThreadPrivate and
updating the object's binding status when moved. This does only work
when the thread is already running, though. If it is not running, we
instead treat the QThreadPrivate's status pointer as a pointer to a
vector of pending objects. Once the QThread has been started, we check
if there are pending objects, and update them at this point.

Thiago Macieira c4d78703e0 forkfd: don't attempt to guess EWOULDBLOCK when WNOHANG is active
Reading the kernel sources, I was sure we'd get an ECHILD if the child
hadn't exited yet, but that's not the case. We only get ECHILD if the
current process has no child processes. But if we do have one and the
one we're waiting for hasn't exited, waitid() returns 0.

So let's not attempt to correct it with forkfd_wait() or forkfd_wait4().
Those have "wait" in the name, so they should behave exactly the same
way. The man pages say:

 waitpid(): if WNOHANG was specified and one or more child(ren)
       specified by pid exist, but have not yet changed state, then 0 is
       returned.
 waitid(): returns 0 on success or if WNOHANG was specified and no
       child(ren) specified by id has yet changed state

This was found while studying QTBUG-100174.

QProcess does not use this code path (blocking mode forkfd only).

instead on a set of overloaded implicit and explicit constructors.

Add the named constructor, with the intent to deprecate the string-ish
QColor constructors after a grace period.

To prevent new users from using known-to-become-deprecated API, mark
the old functions as \obsolete.

Also rename isValidColor() to isValidColorName(). The only reason why
these are lumped together in single commit is so that their docs can
refer to each other instead of having to temporarily refer to obsolete
API.

to a null pointer constant. There's nothing we can do about that one
(even <compare> gives such a warning).

* Several code was depending on flags->int conversions. Add toInt(),
but also cast again to the expected type to avoid warnings in case
toInt() returns unsigned int.

* Ported to explicit casts to bool rather than test(Any)Flag to minimize
confusion for people unfamiliar with the test*Flag methods.

The deprecated Carbon function FSIsAliasFile() returned isAlias only for

with kCFURLIsAliasFileKey returns true for both aliases and symbolic

Since we didn't explicitly check for AliasType in any of our internal

issues, but if we want to expose QFileInfo::isAlias() we need to fix
this.

Timur Pocheptsov bb30beb726 QIOSFileDialog/QIOSDocumentPickerController - handle dismissed view controller
When we use a native view controller for selecting documents, we have
two methods to implement from UIDocumentPickerDelegate (a file was selected
or the selection was cancelled). Unfortunately, swiping a view away
was not handled, so neither 'accept' nor 'reject' was called. Depending
on the classes using QIOSFileDialog, this may leave them in some incorrect
state, not knowing that they are 'closed' anyway.
As suggested by Tor Arne, the solution is to implement
UIAdaptivePresentationControllerDelegate's method, namely
-presentationControllerDidDismiss:, which never gets called if the
controller was dismissed programatically (the case of accept/reject).

Edward Welbourne 93526430a5 Correct handling of {next,previous}Transition before FIRST_DST_YEAR
A recent change introduced a cut-off in believing MS's claims that a
zone has always had a yearly cycle of DST, to stop believing it before
1900, as no actual zone adopted DST that early. However, this was only
applied to the data() method to get the data for a specified time;
failure to do the same for {next,previous}Transition lead to
inconsistent results and tripped up an assertion. The change to data()
also failed to consider the situation of a southern hemisphere zone,
for which the rule will claim the early part of the year was in DST;
and init() should also mark an initial DST-recurrence rule as starting
no earlier than 1900.

Add corresponding FIRST_DST_YEAR checks to {next,previous}Transition()
to be consistent with the one in data(), refine data()'s checking and
amend init().

next, as intended. It needs to be defined at function level, set for
the first rule and updated for each new year tried. Also assert that
it does faithfully reflect the standard time in rules without
transitions.

In the process of fixing that, since it's computed from the
yearEndOffset() of a prior year, test whether that year is less than
the rule start rather than whether the present year is less than or
equal to it. As the prior year is immediately before the present year,

that compared transition times to invalidMSecs(), with an actual
boolean member that gets set when detecting fake DST, so that the

Edward Welbourne 0efebf168d Correct fake-DST detection and handling in QTZP_win
The end-of-year checks previously presumed they would accompany a zero
daylight-savings change there; however, this misunderstands what a
fake transition is doing. A fake at the end of the year means that the
transition during the year is out of the time the fake claims it goes
into, so the offset nominally in effect after the fake should match
the offset the year started in, the same as for a year-start fake.
However, implementing that exposed the fact that Bangladesh's brief
flirtation with DST in 2009 ended at the end of the year, and MS's
data has no other instance (aside from entirely bogusly claiming that
Bhutan did the same in 2009) of an end-of-year transition, in
particular no fake transitions. So the end-of-year case for faking
does not arise and I've eliminated it from the code here. This
greatly simplifies the code to detect fake DST rules.

At the same time, in the ruleToData() wrapper, use the transition
implied by isDst only if it isn't the fake one; the other is the only
real transition in the year anyway, however described. Also, extract
the detection of start-of-year transition times to a function and make
it more exact.

eventually lands.

As an immediate positive contribution, even without the backend ported
away from bool out parameters, the functions can now be marked as PURE

a narrow contract d/t the base argument, which, unlike the return

Ivan Solovev 79fb80152f Android: make sure that orientationChange is reported after resize
On Android orientation changes are reported from the
DisplayListener.onDisplayChanged() method, while the screen size
changes are reported from QtLayout.onSizeChanged().
In practice these callbacks come in random order, so rotating the
screen multiple times might result in inconsistent order of signals
and events.

This patch makes sure that size change events always happen before
orientation changes. This is done by caching the new orientation
values and reporting them only when needed. At this point we also
need to use QMetaObject::invokeMethod() for orientation change,
like it is done for geometry change. Otherwise the orientation
update can still be processed earlier than the geometry change.

Also note that at some point we might get an orientation change
without a size change (for example Qt::LandscapeOrientation ->
Qt::InvertedLandscapeOrientation). That is the reason for
isSimilarRotation() helper function.

As a drive-by: ignore size changes with inconsistent values when window
size is reported to have old orientation, while the screen has already
been rotated. In such cases a new size change will be triggered shortly
with normal value.

Screen has 3 parameters:
- physical size
- screen size (or screen geometry)
- available geometry

Before this patch, they were reported in 3 different methods. Screen
size update and available geometry update both were generating the
"screen geometry changed" event, that updated the user-visible
parameters. As a result, at some point we could end up in an
intermediate state, when screen size was already updated, but
available geometry was not yet updated.
This was specially visible while changing the screen orientation:
at some point screen geometry could be reported for the new
orientation, while the available geometry - still for old orientation.

This patch introduces a new method to set all geometry-related
parameters together and generate only one "screen geometry changed"
event. This allows to maintain consistency between 'geometry' and
'availableGeometry' properties of QScreen.

Giuseppe D'Angelo 0deff80eab Associative containers: add a way to obtain a key/value range
Our associative containers' iterator's value_type isn't a destructurable
type (yielding key/value). This means that something like

  for (auto [k, v] : map)

doesn't even compile -- one can only "directly" iterate on the
values. For quite some time we've had QKeyValueIterator to allow
key/value iteration, but then one had to resort to a "traditional" for
loop:

  for (auto i = map.keyValueBegin(), e = keyValueEnd(); i!=e; ++i)

This can be easily packaged in an adaptor class, which is what this
commmit does, thereby offering a C++17-compatible way to obtain
key/value iteration over associative containers.

Something possibly peculiar is the fact that the range so obtained is
a range of pairs of references -- not a range of references to pairs.
But that's easily explained by the fact that we have no pairs to build
references to; hence,

 for (auto &[k, v] : map.asKeyValueRange())

doesn't compile (lvalue reference doesn't bind to prvalue pair).
Instead, both of these compile:

  for (auto [k, v] : map.asKeyValueRange())
  for (auto &&[k, v] : map.asKeyValueRange())

and in *both* cases one gets references to the keys/values in the map.
If the map is non-const, the reference to the value is mutable.

Last but not least, implement pinning for rvalue containers.

[ChangeLog][QtCore][QMap] Added asKeyValueRange().
[ChangeLog][QtCore][QMultiMap] Added asKeyValueRange().

Lorn Potter 66a76a5def wasm: enable mobile native keyboarding
This works on iOS and Android, and Windows with touchscreen.

On Android, we need to listen to the input event
of a hidden text element and synthesize Qt keyboard
events from that in order to get input events into Qt.

On Windows, we need to be more creative about bringing the native
virtual keyboard up.

Because the entire canvas is contenteditable, we need to specify the
inputmode is set to 'none', otherwise the v keyboard pops up
when user clicks anywhere on the canvas. Therefore we set a hidden
element as contenteditable, which pops up keyboard when Qt
needs it for editable widgets. On Android, this is the same
element that is used to proxy the keyboard input.

Marc Mutz 6f5c78fe3d QFlatMap: add remove_if
The existing API of QFlatMap did not allow efficient removal of
elements:

- std::remove_if does not apply, because it works by moving elements
  back in the range onto those that need to be removed, which doesn't
  work in flat_map's case, because, like for all associative
  containers, the key in value_type is const.

- The node-based erase-loop (over it = cond ? c.erase(it) :
  std::next(it)) works, but, unlike in traditional associative
  containers, is quadratic, because flat_map::erase is a linear
  operation.

According to Stepanov's principle of Efficient Computational Basis
(Elements of Programming, Section 1.4), we're therefore missing API.

Add it.

I couldn't make up my mind about the calling convention for the
predicate and, despite having authored a merged paper about erase_if,
can never remember what the predicate is supposed to take, so be fancy
and accept all: (*it), (it.key(), it.value()), (it.key()). This means
that unary predicates can either not be generic or must be properly
constrained to distinguish between pair<const K, V> and K, but that's
not necessarily a bad thing.

There's no reason to supply a Qt-ified removeIf on top of the standard
name, because this is private API and doubling the names would do
nothing except double the testing overhead.

Eirik Aavitsland 423b650938 Fix painting clipping glitches with fractional scaling
In QPainter, clipping can only be done on whole pixels. The various
ways of specifying a clipping rectangle to the QPainter API have been
inconsistent in how fractional rectangles (either specified directly,
or as a result of fractional scaling) are mapped (rounded) to integer
coordinates.

Also, the mappings have not made sure to keep the edge-to-edge
property of clip rects under scaling. This is particularly important
when scaling QRegions with multiple rects, as QRegion is designed on
the assumption that an area can be described as a set of edge-to-edge
rects.

The fix rounds a clip rect identically with a fill rect. (Indeed, a
followup plan would be to merge QRasterPaintEngine's
toNormalizedFillRect() with the rectangle rounding function in this
commit).

Notably, a QRectF clip is now interpreted the same as a QPainterPath
clip describing the same area.

This modifies d9cc149995

Yuhang Zhao 770ea68588 Windows QPA: Use less magic number
The correct calculation of the invisible frame margin and the window
border width (they are the same thing actually) is the thickness
of the size frame plus the thickness of the padded border. When
DPI is 96, both of them is 4px and thus the invisible frame margin
and window border width is 8px. So previously the empirical
magic number can work normally is because the error is very small.
It's not a big thing because even on a high DPI screen the error
is still very small. For example, on my 4K monitor with 200%
scaling, the error is only 2px, human eyes almost can't find the
visual difference. But since we now know how to calculate these
values correctly, let's use the correct calculation instead. The
magic numbers and empirical expressions just make people confused.

David Faure 74a4d88e9a QAbstractItemModel: fix persistent index corruption when moving columns
QHeaderView creates persistent indexes in
_q_sectionsAboutToBeChanged(), called by the slot connected to
rowsAboutToBeMoved/columnsAboutToBeMoved.

In the case of rows, QAbstractItemModel emits the signal *before*
preparing to update persistent indexes in itemsAboutToBeMoved(),
so it can see the ones newly created by QHeaderView, all is well.

In the case of columns, the emit was done *after* calling
itemsAboutToBeMoved(), so the additional persistent indexes created by
QHeaderView were ignored, and in endMoveRows() we could end up with:
ASSERT failure in QPersistentModelIndex::~QPersistentModelIndex: "persistent model indexes corrupted"

This bug has been there since the very beginning of beginMoveColumns(),
but was undetected because moving columns in a model is pretty rare
(in my case there's a QTransposeProxyModel that turns columns into
rows in the underlying model, and a proxy that handles dropMimeData...)

Marc Mutz 5a39173c34 Don't allocate in qt_asciiToDouble()
The sscanf implementation ensured NUL-termination of the input data,
by copying it, and appending NUL.

Since this function is ignoring trailing garbage and reports the
progress back, we could be parsing the first double in a multi-MiB
buffer. And we'd been copying and copying the buffer for every double
scanned. This is clearly not acceptable.

An alternative is to use the max-field-width feature of scanf. By
giving the size of the input data as the maximum field width in the
format string, we stop sscanf from reading more than the available
data.

This code should let everyone's alarm bells go off: a format string
constructed at run-time is really the last thing one should consider,
but I haven't found a way to pass the field width as an argument, so
bite the bullet and go through with it. Copying potentially MiBs of
data is the worse of the two evils.

Giuseppe D'Angelo b20cf7feee QLabel::setPixmap(): remove the no-op self-masking
When calling QLabel::setPixmap() with a 1bpp pixmap (i.e. a bitmap), and
that pixmap didn't have a mask set, QLabel would then set the pixmap as
its own mask.

This seems to be a no-op due to how QPixmap::setMask is coded:

  void QPixmap::setMask(const QBitmap &mask) {

    // ...

    if (static_cast<const QPixmap &>(mask).data == data) // trying to selfmask
      return;

  }

Moreover, in order to convert the pixmap to a QBitmap, the code would just
straight downcast it, triggering UB (if the input to setPixmap wasn't a
QBitmap to begin with).

I *guess* this was done this way to avoid a QBitmap::fromPixmap call,
which however is not expensive at all if the pixmap is already 1bpp,
which QLabel::setPixmap checks explicitly (before attempting to mask the
pixmap). I don't know the historical reasons for the code to have the
shape it had (and the code history is from before open governance).

So get two birds with one stone: remove the no-op and also the UB.

Volker Hilsheimer 4cca8ee527 QGuiApplication: use translation-based layout direction unless explicitly set
The stored layout direction used to get changed during initialization
to what was auto-detected based on the translation. Changing the
translation then overwrote that stored value, even if an explicit call
to setLayoutDirection was made by the application.

Calling QGuiApplication::setLayoutDirection(Auto) has so far been a
no-op.

Change this logic so that the stored layout direction continues to be
LayoutDirectionAuto also if it's set based on auto-detection, and only
overwrite it when explicitly called with a non-Auto value. This way,
applications can set a layout direction that stays unchanged even when
translators are installed.

Add test coverage that uses a QTranslator.

In practice, this is not a change of behavior, unless applications called
setLayoutDirection(Auto) (which is no longer a no-op), or called
setLayoutDirection() and then installed a translator and expected the
translator's layout direction to come into effect in spite of the explicit
setting.

[ChangeLog][Gui][QGuiApplication] Calling setLayoutDirection with a non-
auto value now disables the auto-detection based on installed
translators. Applications that explicitly set a layout direction and also
want translators installed afterwards to take effect should reset the
layout direction to Auto, which is now no longer a no-op.

uses a version of QWindowsGeometryHint::frame that does not
early out, causing a missmatch in the geometries of the backing

Edward Welbourne dcd87049bb Treat invalid Q(Date)?Time as null when used as an SQL value
In Qt 5, QVariant::isNull() was true when the contained object had an
isNull() that was true; this is no longer true in Qt 6, so we now have
QSqlResultPrivate::isVariantNull() to test is-or-contains
null. However, for date-times, QSqlDriver::formatValue() treats
invalid QDateTime as NULL, since it needs its toString(Qt::ISODate),
which will be empty if invalid. As QDateTime's isValid() is more
stringent than its !isNull(), this can lead to one that's neither
valid nor null, such as QDateTime(QDate(), QTime(0, 0)), producing an
invalid entry in a database.

Do the same for QTime, as its isValid() is more stringent than
!isNull(), and its toString() likewise returns empty on invalid
(although it's not clear it's possible to construct one that's neither
valid nor null). For QDate valid and null are simply complementary.

[ChangeLog][QSql] Handling of QDateTime and QTime values passed to SQL
now consistently treats invalid as null. Some values of these types
are neither valid nor null, which could lead to invalid data being
given to the SQL database. Invalid values are now treated as null to

Thiago Macieira 4be85491e0 QHash: split the x86 AES hash into three separate functions
Instead of performing decisions inside the single aeshash() function, we
have three implementations instead. Those decisions are permanent for
each CPU, so the branch predictor should be pretty good, but hashing is
somewhat performance-sensitive.

We're only adding three of the four possible combinations of AVX512VL
and VAES. Excluded from the implementation are the CPUs that support
AVX512 but not VAES, which are the Skylake-based ones. Those are mostly
found in server CPUs (Intel Xeon Scalable line) as well as top-end
workstations (Intel Core i9), but never made into general desktop and
laptop parts. For those, the performance will remain what it was in Qt
6.3.

VAES is supported in Intel architectures codenamed Sunny Cove and
Gracemont and their successors. That means it's supported in both the E
and P cores of the Intel Alder Lake (12th Generation Core), as well as
future Atom lines. But neither Atoms nor hybrid CPUS have AVX512 (at
least when the E cores are active).

AVX512+VAES is supported for Ice Lake (10th Generation Core), Tiger Lake
(11th) as well as later generation with AVX512 support enabled. Like in
qstring.cpp, we restricted ourselves to 256-bit operations, which don't
cause performance impact and because the 512-bit VAESENC operates on the
fused Ports 0 and 1, so it has the exact same throughput as two 256-bit
VAESENC.

Thiago Macieira b313a5ec32 QHash: invert the case that is excluded: use VAES and AVX512VL
It's not worth having both cases, since they run at the same time. The
difference is which CPUs they run for: the non-VAES AVX512 code can run
on the Skylake-based AVX512 CPUs, which aren't a usual target for Qt
(servers and workstations), while the AVX512 and VAES case includes the
Ice Lake and Tiger Lake desktop and laptop CPUs.

This is not a good trade-off, but is an stepping stone for the next
commit.

exclude the case of simultaneous VAES and AVX512VL support for len <= 32
case. Instead, the aeshash128_lt32_avx256() does not attempt to use
VAES, because we wouldn't be getting sufficient benefit at the cost of
code expansion (AESENC can dispatch 2 per cycle). See simulation at

The code is slightly convoluted with unexpected indentation so most of

Thiago Macieira ad65bbe4c0 qsimd_p.h: disallow building with just -mavx2 instead of full x86-64-v3
It's probably a user mistake that they didn't know what they really
wanted. Since no processor that supports AVX2 fails to support the rest
of x86-64-v3, we should enable all of that so we can make use of its
features. Notably, we may want to use FMA at some point in QtGui, and
the compiler will likely use BMI, BMI2, and LZCNT on its own (see
qnumeric.h).

Compiling with -mavx2 will produce GCC these errors:

Thiago Macieira b7c37e5978 qsimd: Initialize the current state as soon as QtCore loads
Instead of lazily initializing. We usually don't do this in Qt, but in
this case there are two very good reasons for it:

1) the call tp qCpuFeatures() was not trivial, with the need to preserve
   a bit of state in the caller function across the call. GCC appeared
   to generate better code than Clang in this regard, but it still
   implied more cost than we'd like to do runtime detection in
   performance-sensitive places in Qt.

2) the early initialization allows us to use the detected state in GNU
   indirect functions on platforms that support it.

In order to do this, I had to rewrite the QT_NO_CPU_FEATURE environment
variable parsing without QByteArray and instead rely on string.h's
strtok().

This can't be done for static Qt builds on platforms that don't support
the GNU init_priority variable attribute or the MSVC equivalent[1],
because otherwise we can't guarantee that this bit of code runs before
everything else in Qt. For those platforms, we keep the existing lazy
initialization.

For shared builds in those platforms, we can use the dynamic
initialization. All known linkers will sort the static initialization
code in the order in which the .cpp are linked into the library.

The x86 QSimdInitialized variable will be removed in the next commit.

Morten Johan Sørvig 738a11eeac wasm: reliably determine QScreen position
Fix bug where QWindow content would be drawn with an
offset from the QScreen’s topLeft if the page was scrolled.

On Qt for WebAssembly, screen geometry is equivalent
to canvas geometry, where the canvas position is the
position of the canvas on the document body.

getBoundingClientRect() is the correct function to use
here, however it returns a rect relative to the viewport.
Offsetting this rect by offsetLeft/Top can work in some
bases, but this offset is relative to HTMLElement.offsetParent
and not necessarily to the document body.

Determine the correct QScreen position by subtracting
the body position from the canvas position (both relative
to the viewport).

Alexandru Croitor e5b3436255 CMake: Add default launch screen storyboard for iOS apps
Bundle a default LaunchScreen.storyboard file for an iOS app and make
sure it's referenced in the generated Info.plist file.

When launching Qt examples, it ensures the app uses the whole screen
space on the device rather than just a square-ish part of it.

The storyboard file is a copy of the qmake one, which qmake adds
to the Xcode projects it generates.

A custom launch screen can be provided either by setting the
QT_IOS_LAUNCH_SCREEN variable or by setting the
QT_IOS_LAUNCH_SCREEN target property.
The value must be an absolute path to the launch screen file.

The automatic addition of the launch screen entry in the Info.plist
file can be prevented by setting the QT_NO_SET_IOS_LAUNCH_SCREEN
variable to TRUE.

The automatic bundling of the launch screen file in the application
bundle can be prevented by setting the
QT_NO_ADD_IOS_LAUNCH_SCREEN_TO_BUNDLE variable to TRUE.

The current implementation has a limitation that only one launch
screen storyboard and one iOS executable can exist within a project.

If there are multiple executables in the project, all of them will
use the launch screen that is specified last (the last
qt_add_executable call).

Because of this limitation, the API is marked as Technical Preview,
to be improved upon in the future. For now it simply serves as an
improvement to the out-of-the-box experience of iOS apps built
with CMake.

Thiago Macieira 705ea62f9e QJsonValueConstRef: prepare for Qt 7
Instead of storing a pointer to the QJsonArray or QJsonObject (like the
Qt 4 & pre-5.15 versions did), do like QCborValueConstRef and store the
pointer to the QCborContainerPrivate.

Unlike QCborValueRef, we must keep the is_object bit because of API
behavior that assigning an Undefined to an object reference deletes it
from the container. I've chosen to use size_t instead of qsizetype for
this because then we don't lose any bits of the index. Therefore, the
index in the case of objects is stored as pair count (like before),
different from QCborValueRef which stores the actual index in the
QCborContainerPrivate.

It's the LSB (on little-endian architectures) so the calculation of
2 * index + 1 is the actual value stored in memory or in the
register. Unfortunately, right now, both Clang and GCC don't realize
this and generate unnecessary instructions. Clang:

0000000000000000 <QJsonValueConstRef::concreteType(QJsonValueConstRef)>:
   0:   mov    %rsi,%rax
   3:   shr    %rax
   6:   mov    %rsi,%rcx
   9:   or     $0x1,%rcx
   d:   test   $0x1,%sil
  11:   cmove  %rax,%rcx

[GCC code is identical, except it uses an AND instead of TEST]

That OR at offset 9 is a no-op because it sets a bit that is already set
in those conditions. At least they don't do unnecessary shifts.

Unlike the CBOR counterparts, JSON support has this extra functionality
that assigning Undefined causes the item to be removed from the object

And unlike QCborValueRef, we detach on assignment, not on the obtention
of the QJsonValueRef. This is more dangerous, so we may want to revise.

Thiago Macieira c1780165ee QJsonValueConstRef: optimize to{Int,Integer,Bool,Double,String}()
The CBOR-based implementation from Qt 5.15 simply created a QJsonValue and
then called the equivalent function on that result. For integrals and
double where the QJsonValue matched the asked type, the cost was minimal
anyway. For the other types and when the type didn't match, this
resulted in up/down the reference counter in QCborContainerPrivate and
an out-of-line call to the destructor.

This improves the performance for code like:

  for (QJsonValue v : array) {
      if (v.toString() == x) {
          doSomething();
      }
  }

This change propagates the inadviseable behavior of allowing a
dereference of the end() reference in concrete() to concreteType() (and
unit-tests it) but does not do the same for the toXxx() functions. Doing
that causes a dereference of QList's end() iterator, which is UB
(asserts false in debug mode).

Commit 35adb74ddd ("Reimplement JSON

stored in the QJsonObject::iterator. The same mistake was propagated
when QJsonObject::iterator was converted to QJsonValueRef. This had no
ill effects because the o->elements container would always contain more
elements, but it meant the check was ineffective and meant nothing.

So instead of doing nothing when the iterator does not point to this
container, simply assume it does. Bad things will happen if you try to
erase an iterator that points to another container, but that's true for
almost all container/iterator mechanisms.

Drive-by modernization of some of the surrounding lines.

Thiago Macieira 04dc959d49 Introduce Q{Json,Cbor}ValueConstRef
I screwed up when I wrote QCborValueRef by not having the ConstRef
type. The code worked, but it wasn't const-correct, allowing you to
write:

  const QCborArray &arr = something();
  *arr.begin() = QCborArray();

This mistake was brought over to QJsonValue in Qt 6.0, so it has to be
fixed for QJsonValue too. The actual fixes are in the next couple of
commits.

This change is believed to be binary-compatible: the Q{Json,Cbor}ValueRef
classes continue to have the exact same size, except that they're now
empty and have a new base class. They weren't trivial before this commit
doesn't change that.

[ChangeLog][Potentially Source-Incompatible Changes] The iterator
classes for Qt's JSON and CBOR containers (array and map/object) had a
const correctness issue which allowed a const_iterator to mutate the
container being iterated on, even if that container was itself const. Qt
6.4 has a fix for this, but will cause compilation issues where
QCborValueRef and QJsonValueRef were used where the correctness could be
violated. To keep code compiling with both 6.3 and 6.4, either change to
non-const iteration or replace the QxxxValueRef with a const QxxxValue
reference. This change is binary-compatible.

Ivan Solovev 60799fc141 Android A11Y: Fix value rounding
QAccessibleInterface stores values as QVariants. When dealing with
double values, as a result of some calculation (for example, Slider
value update), rounding errors can be introduced.
When converting double values to QString using QVariant::toString(),
these rounding errors result in strings like
0.30000000000000004 instead of 0.3 or
2.7755575615628914e-17 instead of 0.3 - 3 * 0.1 and similar zeroes.

To fix this issue, this patch introduces a custom conversion for
floating-point values. The idea is to convert QVariant to double,
and then convert double to QString using 'f' format and a suitable
precision, determined from the UI element's minimumStepSize(), if
it has one, otherwise falling back to QString::number()'s default
(which is 6).

Ivan Solovev a374d59abc Android A11Y: Announce value together with element name when focused
Before this patch when we focus a new element, only its description
was announced.
For elements like Slider that means that if it had no accessible name
or description, its value would be announced (all is fine here).
But if the slider is defined like that:
 Slider {
     Accessible.name: "int slider"
     value: 5
     from: 0
     to: 20
     stepSize: 1
 }

only the name ("int slider") will be announced, but not the actual
value.

This patch fixes the logic of content description generation. If the
element has value, then it is added to the description and announced
as well.

Before this patch Android A11Y implementation was missing
ValueChanged event handling. As a result, no update was given

Handling these events allows us to announce value changes on such

This is a universal method of value-change announcement, so it
supports all sorts of A11Y gestures.

On the Java side a new function was introduced to announce the
values, because we need to use the actual element's *value*,
not its accessible name or description.

has to be freed (with free) later to avoid a leak, which we so far
didn't.
This patch ensures that we always clean up the memory by using a

- Always pass either the stack buffer or nullptr to realpath.
- Rely on realpath returning nullptr in the error case.
Lastly, fix a few coding-style issues.

completion of that QLineEdit is drawn in the wrong location. When the completer
getting the rect of screen, it gets the rect of the QGraphicsScene where
QLineEdit is located rather than the rect of the screen, resulting in an error
in the following calculation.

Note that as long as the completer popup is a toplevel widget not parented
to the target widget, it will not be automatically embedded into the graphics
