Cannot just do like with other APIs and expose a view of multiple
array layers. The only option is to use the multiview-specific API
and specify layers 0..view_count-1 in the depth texture.
This allows having depth in a multiview render pass with OpenGL.
Note that this does not cover stencil. D24S8 does not work, so
we may need to explore having a dedicated, separate stencil
texture.

This is similar to and extends the prevention of thread cancellation
introduced by commit ba05af82d3. This
prevents the situation in which a signal gets delivered (usually because
of a crash) and the parent process' handler is run, doing things it
shouldn't between vfork() and execve().
Most C libraries (all that I've investigated) unblock SIGABRT on
abort(), so this doesn't affect them. Likewise, on most OSes, crashes
ignore the signal block and terminate the application -- Darwin appears
to be an exception, but vfork() is not enabled there. Both situations
are tested by terminateInChildProcessModifier().

This fixes a crash while parsing an XML file with garbage data, the file
starts with '<' then garbage data:
- The loop in the parse() keeps iterating until it hits "case 262:",
which calls fastScanName()
- fastScanName() iterates over the text buffer scanning for the
attribute name (e.g. "xml:lang"), until it finds ':'
- Consider a Value val, fastScanName() is called on it, it would set
val.prefix to a number > val.len, then it would hit the 4096 condition
and return (returned 0, now it returns the equivalent of
std::null_opt), which means that val.len doesn't get modified, making
it smaller than val.prefix
- The code would try constructing an XmlStringRef with negative length,
which would hit an assert in one of QStringView's constructors
Add an assert to the XmlStringRef constructor.
Add unittest based on the file from the bug report.
Later on I will replace FastScanNameResult with std::optional<qsizetype>

When a table view adds its first row, QHeaderView::initializeSections()
is called. It initializes the vertical header view with the number of
added sections. Subsequently QHeaderView::sectionsInserted() is called
with the same amount of newly added rows/sections.
That leads to the initial amount of sections being 2x the number of
rows added in the first go. In other words, the table view will display
at least one row more than the underlying table model has.
This patch adds an OR condition to the early return check at the
beginning of QHeaderView::sectionsInserted(). The method returns early
if the number of sections equals the number of respective sections
(rows in this case) in the model.

33c88f86b5 added some logic to QAPM in

to prevent QAPM from asking for illegal indices in order to implement
automatic remapping of the section headings (since there's no
mapSectionToSource).
The commit seems to have introduced a regression in QHeaderView, which
isn't prepared to receive headerDataChanged while a row/column count
change is in progress. When receiving headerDataChanged, QHeaderView
will try to read the row/column count and will store it internally.
When it will then receive the signals for insertion/removal of
rows/columns, it will interpret it as a modification of the previously
stored value -- even if the value it stored was already correct.
Fix this by avoiding to have two signals in flight at the same time;
emit headerDataChanged as a queued invocation.

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.

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.

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.

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.

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
take scrolling into account.

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.

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.

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().

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.

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.

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.

In QAccessible's widget implementations, trees are treated as tables,
with a rowCount implementation that is based on the view's current
item content. That item content is the view's content, not the model's,
and it changes when tree branches are expanded.
The Cocoa bridge for accessibility allocates arrays of row data
structures based on the rowCount implementation. Those data structures
need to be invalidated and recreated when the view's content changes.
To do that, emit an accessibility event for a model reset when laying
out items changes the size of the view's item array. We don't know what
changed during that layout process to makes this any more granular.
Amends 11ae55e918, but the problem
with the data structure being stale and incorrect would have been there
before that chain of changes optimizing. It didn't trigger an assert,
but probably resulted in incorrect data being reported.
To make trees testable, we need to actually expose them as AXOutline
to the macOS accessibility framework. Until now, they have been treated
like plain QWidget, e.g. AXGroup. This made them in practice in-
accessible. With this change, VoiceOver works much better (although not
perfeclty yet).
Also remove an assert that could be triggered by an accessibility
client asking for a cell for an invalid index (which can be reproduced

It is necessary to add an AccentColor role to QPalette.
QPalette currently has 21 color roles and 3 color groups, which
require 63 bits to resolve. The resolve mask is implemented with a
qint64, which doesn't provide spare bits for another color role.
The color role NoRole is used as a default value, marking that a role
has not (yet) been defined. The enum value does not represent a valid
brush, even though it can theoretically be stored in QPalette's shared
data.
This patch adds the enum value AccentColor to QPalette::ColorRole,
increasing the available color roles to 22.
To keep the resolve mask at 63 bits, AccentColor is mapped to NoRole
in static constexpr bitPosition.
As the enum range would exceed 64 bits without this tweak, 3 additional
bits are substracted in the respective static assertion.
With NoRole having no bit in the resolve mask, the following adaptions
have been implemented:
- QPalette::resolve() is adapted to explicitly ignore NoRole.
- QPalette::isBrushSet() always returns false for NoRole.
- tst_QPalette::setAllPossibleBrushes() to verify the latter
- operator== ignores NoRole (documentation updated)
AccentColor is added in tst_QPalette::roleValues and enum documentation
is adapted.
In QPalette's default constructor, the AccentColor brush is defaulting
to the Highlight brush, it this is available. Otherwise it is made 30%
darker or lighter than the Base brush, depending on dark/light mode
heuristics.
QPalette's data stram functions have been extended from QDataStream
Version Qt_6_6. If earlier versions are de-serialised, the AccentColor
defaults to Highlight. An autotest function dataStream() has been added
to tst_QPalette.
The QDataStream Version Qt_6_6 has been bumped to 21.
tst_QDataStream has been adapted to the new version and the new
color Role.

qrhi.h, qshader.h, qshaderdescription.h (and qshaderbaker.h from
shadertools; done separately) become "RHI APIs", following the concept
of QPA APIs.
Mirror completely what is done for QPA headers, but using the "rhi"
prefix for the headers. This involves updating syncqt to handle the
new category of headers. (a note on the regex: matching everything
starting with "qrhi" is not acceptable due to incorrectly matching
existing and future headers, hence specifying the four header names
explicitly)
There is going to be one difference to QPA: the documentation for
everything RHI is going to be public and part of the regular docs, not
hidden with \internal.
In addition to the header renaming and adding the comments and
documentation notes and warnings, there is one significant change
here: there is no longer a need to do API-specific includes, such as
qrhid3d11[_p].h, qrhivulkan[_p].h, etc. These are simply merged into a
single header that is then included from qrhi.h. This means that users
within Qt, and any future applications can just do #include
<rhi/qrhi.h> (or rhi/qshader.h if the QRhi stuff is not relevant), no
other headers are needed.
There are no changes to functionality in this patch. Only the
documentation is expanded, quite a lot, to eliminate all qdoc warnings
and make the generated API docs complete. An example, with a quite
extensive doc page is added as well.

There are two types of stack unwinding that can happen on Unix systems:
C++ exceptions and PThread cancellations (on some systems, like Linux,
PThread cancellations can be caught in catch(...) statements). We call a
variety of PThread cancellation functions from inside the child stub,
like close(). To avoid problems, we disable PThread cancellations
completely before fork() or vfork().
The C++ exception case is simpler, because we can be sure of catching
them with the catch (...) statement and simply transform them into an
error message. This is also testable, which the PThread cancellation
isn't.
The error message isn't ideal because we're string-frozen. I'll improve
it for 6.6.

While generate_n is above any reasonable suspicion of copying the

to copy.
