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.
An autotest is added in tst_QTableView::rowsInVerticalHeader().

33c88f86b5 added some logic to QAPM in
order to have it automatically emit headerDataChanged when rows/columns
were added or removed in the model. This was done as a stopgap measure
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.

our test themes inherit system themes such as crystalsvg and gnome,

In that case, it will show 'up' and 'down' widgets in the

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

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

This patch will make sure that we always scroll the list view
to the top before we start calculating where the popup should

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

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

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.

This no longer is range-length preserving now, so adapt the

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
