b7d9b7fa69 rhi: d3d12: Implement multiview support
This relies on qsb being able to invoke dxc instead of fxc when the
request HLSL (shader model) version is 6.1.  (6.1 is required for
SV_ViewID) This currently works only when conditioning offline with
qsb (or via CMake), because qsb can easily invoke dxc instead of
fxc. When shipping HLSL inside the .qsb package (so when -c is not
specified or running the external tool fails), this won't work since
the D3D12 backend still uses D3DCompile(), not IDxcCompiler. Support
for that will be investigated separately.

We also need to bump to ID3D12Device2 and ID3D12GraphicsCommandList1.
With Windows 10 version 1703 being quite old now, this should not be a
problem at run time.

There are however issues at build time, namely that MinGW and
MinGW/LLVM and similar seems to have ancient Windows SDK headers
according to the CI test runs. None of the MSVC configurations have
this in the CI, they have reasonable versions of d3d12.h and similar.

Therefore, one important aspect of this change is that the D3D12
backend of QRhi will only be available from now on when the SDK
headers are new enough (meaning ID3D12Device2 is declared, which is a
several years old type now). Otherwise, QRhi::create() will simply
fail when asking for D3D12 with a helpful warning message about the Qt
build being crippled.

Implementation-wise, there are surprises in store as well:

The way the PSO is created needs to be revamped to follow the
extensible approach that uses a pipeline state stream
description. Both the graphics and compute pipeline creation is
changed to use CreatePipelineState() and the associated
machinery. This is only really essential for graphics pipelines since
we know have to include data for view instancing (multiview). For
compute the result is the same as before.

Additionally, the view count must now be baked into the
QRhiGraphicsPipeline. This means that applications must call
setMultiViewCount() with the same value (typically 2) *both* on the
render target's color attachment and on the pipeline. Backends that do
not care about the pipeline's view count (GL, Vulkan) will of course
ignore it, but if it's not set correctly D3D12 will fail. The manual
test is updated accordingly.

2b9ef2eb44 Pacify MSVC compiler incorrectly warning about unused variable
Under some circumstances, MSVC seems to complain about SlotArgumentCount
being unused

  qobject.h(210): warning C4189: 'SlotArgumentCount': local variable is
  initialized but not referenced
  note: see reference to function template instantiation
  'QMetaObject::Connection QObject::connect<void(__cdecl QAction::* )(bool),
  main::<lambda_1>>(const QAction *,Func1,
    const QtPrivate::ContextTypeForFunctor<main::<lambda_1>,void>::ContextType *,
    Func2 &&,Qt::ConnectionType)' being compiled

This is nonsense, as SlotArgumentCount is used in the next line, to
construct the list of signal arguments, but the workaround to declare
the variable as [[maybe_unused]] is trivial.

Add a connect statement to the test case that creates such a connection.
This does not produce any warning with or without the attribute (and if
it did, the build would fail for CI configuratinos setting -Werror).

e8dcbaaaf6 QFutureSynchronizer: fix aliasing problem in setFuture()
When setFuture() was handed an element of m_futures, it would hold the
reference to past the clear(), which invalidates said reference.

Fix by taking the future by value instead of by cref.

While append() is not affected, as QList::append() already guards
against aliasing, do the same change there, both for consistency as
well as to optimize the common case of passing rvalues. It also means
we can use the rvalue overload of QList::append(), skipping the alias
analysis in the lvalue QList::append().

setFuture() if the argument was already a member of
QFutureSynchronizer::futures().

f83ea89622 Implement QWidgetPrivate::focusObject()
QWidgetPrivate::focusObject() always returns nullptr. That has lead to
mismatches between QGuiApplication::focusObject() and
QApplication::focusWidget(), when a widget got focus by the window
system (e.g. mouse click).

This patch implements QWidgetPrivate::focusObject.
It returns the current widget, if it doesn't have a focus proxy.
If it has a focus proxy, it resolves the proxy chain and returns the
deepest focus proxy.
(Note: It does not return QWidget::focusWidget(), because the focus
widget might not yet have been set, when the method is called).

5664424085 QPixmapCache: don't leak QString keys of evicted pixmap
It's not a real leak in that the string data is being freed on program
exit (or, more recently, QPixmapCache::clear()), but it can lead to
lots of memory being bound for much longer than expected when users
put in new QString keys without attempting to retrive them again. It
can also lead to problems with QStringLiterals lingering around until
after their underlying data has been freed. A bug in the Fusion style,
generating new string keys for identical state, exposed this
misbehavior, and one way to fix the resulting issue for the user is to
make sure that QPixmapCache doesn't leak QString keys.

The Fusion style issue with generating non-repeating keys for use with
QPixmapCache should also be fixed, eventually, but this patch
relegates that to an optimization issue (the caching is effectively
non-existent), the resource exhaustion is gone now.

The issue exists because the QString keys are internally mapped to
QPixmapCache::Key's by way of a QHash<QString, Key> cacheKeys data
structure. When the QCache, indexed by Key, not QString, decides to
evict an entry, the Key is invalidated, but no-one was removing the
corresponding entry from cacheKeys. So make the existing releaseKey(),
used to invalidate copies of Keys referring to evicted pixmaps, do
that, now. So as not to have to scan the whole cacheKeys QHash for the
right Key, store the QString key, if any, inside the Key, so
releaseKey() can retrieve it and use it for O(1) erasure from
cacheKey.

This allows removing the previous work-around in clear()
(6ab0d25a09), greatly simplify
object(QString), and requires to rewrite all code that holds iterators
or references into cacheKeys over an insertion into or removal from
the QCache. Two (insert() and remove()) have already been done in
prequel commits, so only flushDetachedPixmaps() was left.

96e1381a0a QBindable: Fix out-of-bound access in non-bindable property support code
QObjectPrivate::getPropertyAdaptorSlotObject called
connectionsForSignal.
Calling this function is only safe after it has been ensured beforehand that the vector has size > signalIndex. As getPropertyAdaptorSlotObject
is not supposed to modify the vector, it does not resize the vector and it could consequently end up with an out-of-bounds read.

To avoid that issue, we instead first check if the vector can
potentially contain an entry for the signal. If not, we simply return
nullptr, and avoid the call to connectionsForSignal.

The issue and its fix can be verified by running the modified
tst_qproperty test with ASAN enabled. The test is modified in the
following way:
- We first create a signal connection to a dummy slot. Otherwise,
  connections.loadRelaxed() would return a nullptr, and the problematic
  code would never be reached.
- We add enough signals to ensure that the fooChanged signal will
  actually be out of reach (which means >= 8 signals, as the initial
  capacity of the vector is 8)
Running the test without ASAN will most likely not result in a failure,
as then the out-of-bounds read will simply read garbage, and the most
likely result is that the cast below will fail.

f4dca7c512 Consult QIcon::fallbackThemeName() even for themes with explicit parents
We would previously only use the fallback theme for themes that did
not exist, or for themes that did not declare any parent theme.

We now unconditionally use the fallback theme, even for themes that
declare their own parent themes, so that a QIcon::fromTheme("foo")
that doesn't exist in the current theme, nor any of its parents,
nor in "hicolor", will still be looked up in the fallback theme.

The reason this seemed to work in the existing tests was because
our test themes inherit system themes such as crystalsvg and gnome,
and we didn't provide a hicolor theme. Any of these themes missing
would lead us into the code path where we use the fallback theme
for a missing theme, masking that fact that we had not added the
fallback theme to the list of fallbacks for the theme that had
explicit parents declared.

The logic has been moved out of the theme parsing and into an
accessor in QIconTheme, so that we're not caching the fallback
theme lookup.

used as fallback even for themes that declare a parent theme.

8393922e70 QComboBox: scroll the popup to the top before positioning it
If the style changes while a popup is open (or about to close),
the popup will change style as well before it's hidden. And
this can result in the popup window briefly ending up smaller
than what it needs to be, in order to fit all the menu items.
In that case, it will show 'up' and 'down' widgets in the
menu that auto scrolls it when hovered. And all this can
happen for a split second while the menu is about to close
(as a result of the user clicking on a menu item).

A bug happens because of this if you click on the last menu
item in the list, and this causes the style to change. In
that case, the 'down' widget will end up directly underneath
the mouse for a split second, which will trigger an auto-scroll
timer to start. This timer will trigger a bit later, after
the popup has been hidden, and scroll the list view a bit down.
The result is that the next time you open the popup, it ends up
at the wrong place on the screen in a failed attempt to center
the current index on top of the combobox.

This patch will make sure that we always scroll the list view
to the top before we start calculating where the popup should
be placed on the screen. Otherwise the geometry ends up wrong
since the popup will anyway be resized (if possible) to fit
all the menu items before it's shown and should therefore not

b86f368441 Long live futexes for FreeBSD!
Like commit 91f6460aff which added support
for Windows. This API is documented and has apparently been present in
FreeBSD for a long while.

The DragonflyBSD API is very similar, but I don't have one to confirm
that I've coded correctly. OpenBSD and NetBSD may have similar APIs, but
I haven't even researched them. We're open to contributions, though.

fc4fca6d9d Support child windows on WASM
Setting parents for WASM platform windows is now supported. This means
that windows now reside in a hierarchical window tree, with the screen
and individual windows being nodes (QWasmWindowTreeNode), each
maintaining their own child window stack.

The divs backing windows are properly reparented in response to Qt
window parent changes, so that the html structure reflects what is
happening in Qt.

af8f9a2a6e QStringBuilder: allow to be used with 'auto' keyword
The idea is to store a concatenable in a QStringBuilder object by value
or by reference, depending on how it was originally passed into the
concatenation operator. So if it was passed by r-value, we treat it as
a temporary object and hold it by value (and use move-semantic if
available), otherwise we hold it by reference (as before).

To achieve this we first change concatenation operators '%' and '+'
to take their arguments by universal reference. Next we instantiate
QStringBuilder object with deduced types of the arguments, which will
be a "value type" or a "reference type" according to "universal
reference deduction rules".

Further we use perfect forwarding to pass arguments to QStringBuilder's
constructor. Thus arguments, initially passed by r-value reference
and which are move-constructible, will be "moved" to corresponding
QStringBuilder member variables.

So, to summarize:
1. Arguments passed by l-value reference - stored in QStringBuilder
   object by reference (as before).
2. Temporary objects passed by r-value reference - stored in
   QStringBuilder object by value. If a type is move-constructible
   (QSting, QByteArray, etc), the object will be "moved" accordingly.

Special thanks to Giuseppe D'Angelo for the tests.

These APIs started out as private APIs in qnumeric_p.h, but have since
been made pseudo-public in qnumeric.h. The qnumeric_p.h versions just
forward to the qnumeric.h ones, so just use the latter.

This is in preparation of removing the {add,sub,mul}_overflow
versions, which, despite being defined in the unnamed namespace, don't
sport the q prefix, so potentially clash with global symbols.

The change is a simple textual search and replace, manually excluding
qnumeric_p.h.

1f22fc995a Fix segfault when using qfuture continuations with move only types
When using move-only types, continuations args are set using takeResult
function, which has the side effect of invalidating the QFutureInterface
associated with the promise/futures by:

1. setting isValid to false
2. setting the state to NoState

And when the promise is destroyed, it tries to run the continuations if
`finished()` is not called, which is done by checking the Finished bit
in the state. But since the continuation has been run before, and the
state has been set to NoState it tries to run the continuation again
causing a segfault. Multiple solutions come in mind:

1. don't run the continuation if the state is NoState, but this would
   break the case when an empty promise is destroyed
2. check inside the continuation if it has been run before, and if so
   don't run it again, but this seems hacky since we don't want the
   continuation to be run twice, and it should break if it did.
3. when invalidating the promise leave the state as is, and change
   isValid only to false, which changes the current behavior, but is
   still compatible with the documentation which states only that
   isValid will return false if takeResult is called

I chose option 3

I also extended some tests to test for move only types, and added a test
that continuations run when a promise is finished. This simple case
would segfault before with move only types.

78cdd9a64d QPixmapCache: deprecate replace()
The replace() implementation overwrites the passed Key key with a new
version, const_cast'ing away the const from the key passed by
reference-to-const. This is UB if the Key was originally declared
const.

Deprecate the function.

Also inline the const_cast, so compilers can readily detect the UB
even if users don't enable deprecation warnings. Due to the severity
of the issue (UB), immediate deprecation is warranted. There appear to
be no in-tree user of the API outside of tst_qpixmapcache.cpp.

[ChangeLog][Deprecation Notice][QtGui][QPixmapCache] The `replace(key,
pixmap)` function has been deprecated, because passing a `const Key`
to it results in undefined behavior. Use `remove(key, pixmap)`
followed by `key = insert(pixmap)` instead.

it is impossible to only use this information to find delete events

the information on loop level.

QDeferredDeleteEvent, so that we can check whether an event was posted
before the outermost event loop (for which we need to compare only the
loop level).

QDeferredDeleteEvent was also made private as it should - it is an
implementation detail that wasn't hidden properly.

05e3880130 QString: add STL-style assign() [3/4]: (it,it) overload for char32_t
This no longer is range-length preserving now, so adapt the
documentation.

For the non-contiguous iterator case, it's actually ok to always
resize(0) and then append(), because, unlike for QList and QVLA, the
resize(0) doesn't actually iterate the container to destroy
elements. It just sets some members and conveniently detach()es for
us.

The char8_t case is even more complicated, since we can, atm, not
include qstringconverter.h into qstring.h, yet qstringconverter is
required for stateful UTF-8 decoding in the input_iterator case. So
that's postponed to yet another patch, and maybe won't make it into
6.6. But I feel it's important to have at least one
non-length-preserving version of assign(it, it) in before release lest
users come to rely on this documented (and de-facto) feature of the
the step-2 assign().

2a7da1b3c8 QTabBar: recalculate scroll offset when showing
If an application sets the current index and resizes the tab widget
before showing it, then the scroll offset might be calculated based on
an old size. Since after ca15f650a1,
resizing explicitly avoids scrolling, this could result in tabs ending
up scrolled outside of the tab bar when showing the tab widget.

Fix that by explicitly making the current tab visible in the tab bar's
showEvent handler, which recalculates the scroll offset based on the
actual size.

This is only reproducible with a tab widget, which lays out the tab bar
for each change and resets the tab bar's layoutDirty flag. Add a test
case there.

6ab0d25a09 QPixmapCache: fix leaking of QStrings and Keys on clear()
QPixmapCache maintains a mapping from QString to QPixmapCache::Key, in
the form of the cacheKeys QHash, but QPixmapCache::clear() didn't
touch it, leading to the string data (as well as the Keys) being
retained after any possible use. This can lead to memory slowly being
eaten up, as reported in QTBUG-112200, and prevents a periodic calling
of QPixmapCache::clear() from being a work-around for the issue in the
bug report.

Fix by clearing cacheKeys in QPixmapCache::clear().

This is designed as a low-risk enabler of a work-around, not a fix for
the issue. The work-around enabled by this is periodic calling of
QPixmapCache::clear().

b9491daad0 Modernize the qtloader
This is a minimal version of qtloader. The load function accepts
the same arguments as emscripten runtime with a few additions:
- qt.environment
- qt.onExit
- qt.containerElements
- qt.fontDpi
- qt.onLoaded
- qt.entryFunction

State handling has been removed in favor of making the load async
(assume loading when the promise is live).

Public APIs getting crashed status, exit text and code have been
refactored into the new qt.onExit event fed to load. No need for
keeping the state in the loader.

The loader is integration-tested. A test module with test APIs
has been created as a test harness.

The runtime APIs exposed by Qt (font dpi and screen API) are handled
by the qtloader seamlessly.

60f739f51f tst_ContainerApiSymmetry: make assign_impl() more robust
Refactor the 'CHECK' macro to eliminate the capacity check and
explicitly verify that no reallocation occurred. The previous
implementation had to pass constants to suppress the issue arising
from differing growth rates between implementations.

Additionally, improve the 'std::stringstream' versions of the test
by incorporating the correct values. In the previous implementation,
the usage of:

    auto tData = V(9);
    ~~~
    std::stringstream ss("9 9 ");

had several issues. Firstly, it used the wrong test data since the
container's value_type of '(char) 9' resulted in a tab character '\t',
which was not accurately reflected in the stringstream assignment.
Secondly, this value caused problems in how stringstreams interprets it.

To address these issues, let's make the following improvements:

1. Use a default test value of 65 instead of (char) 9. This value, which
represents the character 'A', is less likely to cause errors and is more
intuitive.
2. Use the tData variable for the assignments in the stringstream. This
ensures that the correct data from the container is used.
3. Change the test value between the assign() calls to verify that the
container's contents are successfully overwritten.

These changes ensure, that the test cases are more accurate and
reliable.

07d6d31a4c QFuture: Gracefully handle a destroyed context in continuations
This patch relaxes the requirements on the context object of
continuations. Instead of having to stay alive during execution of the
whole chain, it now only has to stay alive during setup of the chain.
If the context object is destroyed before the chain finishes, the
respective future is canceled.

This patch works by using QFutureCallOutInterface and signals instead
of direct invocation of the continuation by the parent future, similar
to how QFutureWatcher is implemented.
If a continuation is used with a context object, a QBasicFutureWatcher
is connected to the QFuture via a QFutureCallOutInterface. When the
future finishes, QBasicFutureWatcher::finished() triggers the
continuation with a signal/slot connection.
This way, we require the context object to stay alive only during setup;
the required synchronization is guaranteed by the existing event and
signal-slot mechanisms. The continuation itself does not need to know
about the context object anymore.

[ChangeLog][QtCore][QFuture] Added support for context objects of
continuations being destroyed before the continuation finishes. In
these cases the future is cancelled immediately.

432d67b43f QDnsLookup: add TimeoutError for timeouts
We were getting InvalidReplyError because it was simply unknown, which
is not very useful. Previously, the Unix code used res_nquery(), which
does not return timeouts as a condition. It returns -1 if a timeout did
happen, but the content in errno could be a left-over from a previous
timeout (see the "Not a typewriter"[1] problem).

With the rewrite to using res_nmkquery() and res_nsend() from the
previous commits, we can rely on errno being set properly by
res_nsend().

bdbfa7757a QWindow test: Blacklist enterLeaveOnWindowShowHide
This test fails too frequently on Android and RHEL to leave in as
significant. The bug report is already closed after timeouts were
extended, so perhaps we just have to accept the status quo. No
point in keeping tickets open for tests that we can't get stable on
some platforms.

Pick-to: 6.5

6a2b029138 QLabel: always show the context menu created by the control
Amends e718818745, after which a context
menu was only shown if the format was rich text and there was a link at
the position of the click.

We always want to leave it up to the control to create a context menu,
so only return early if there is no control. The control will then
respect content at the position (i.e. link or not) and text interaction
flags, and create the menu based on that. I.e. a rich text label with
selectable text should still show "Select All" in the context menu, also
if not clicking on a link.

Add a test case to verify that the context menu event got accepted
as expected, which indicates that the label showed a menu.

Pick-to: 6.5
