483ae6c448 StyleSheet: use item background rule when filling row backround
QTreeView draws the different sub-rects of an item's background over
multiple calls to drawPrimitive(PE_PanelItemViewRow). The item row is
not separately stylable, but the item might have a styled background
property. To get a consistent background, we must use the item's
background rule when filling the item's row background.

To fix that, delegate the filling of the branch background to
drawPrimitive(PE_PanelItemViewRow), and implement PE_PanelItemViewRow
handling to render the rule for the ViewItem pseudo element if there is
a background rule defined for it.

Add a baseline test stylesheet for this scenario. Note that the selection
in an item view is better styled via the selection-background-color
qss property.

The fix for QTBUG-73251 in f4976f86cd
resulted in QTBUG-106227. Add baseline test coverage for the respective

bea5649cd1 Windows: bump NTDDI_VERSION to latest version and remove some duplicated code
We have NTDDI_WIN10_NI (0x0A00000C) in the Win11 SDK (10.0.22621)
so bump the value in Qt (currently 0x0A00000B) to it.

And when searching for _WIN32_WINNT/WINVER/NTDDI_VERSION throughout
the whole qtbase codebase, I found some duplicated code, mostly
leftovers from the legacy time. Replace them with our own windows
header can achieve the same effect: we have defined all the necessary
macros to unblock the latest features. And place the header at the
top most place to include the macros as early as possible.

c3e2a624fb QApplication: send QHoverEvents with correct scenePosition()
The QHoverEvent ctor takes two points: pos and globalPos; pos is then
passed as both the scene and global pos to the QSinglePointEvent ctor,
which calls QMutableEventPoint::setScenePosition() on the persistent
QEventPoint instance and then detaches befeore setting ephemeral state.
Therefore, we must construct QHoverEvent with scene position first, not
local position, so that the right value is persisted; it's better to set
local position after the detach(), whereas it's too late to fix the
persistent point then.

e2fef733be Replace usages of Q_CLANG_QDOC with Q_QDOC
To allow the user to customize the C++ code that QDoc sees, so as to be
able to work-around some limitations on QDoc itself, QDoc defines two
symbols: Q_QDOC and Q_CLANG_QDOC, both of which are "true" during an
entire execution of QDoc.

At a certain point in time, QDoc allowed the user the choice between a
custom C++ parser and a Clang based one.

The Q_QDOC symbol would always be defined while the Q_CLANG_QDOC symbol
would be defined only when the Clang based parser was chosen.

In more recent times, QDoc always uses a Clang based parser, such that
both Q_CLANG_QDOC and Q_QDOC are always defined, making them equivalent.

To avoid using different symbols, and the possible confusion and
fragmentation that derives from it, all usages of Q_CLANG_QDOC are now
replaced by the equivalent usages of Q_QDOC.

Since 4! = 24, 128 retries should be more than enough to ensure we do
find at least hash seed that provokes a different order.

c10132888e tst_QCryptographicHash: avoid duplicate data tags
Use key(i) rather than valueToKey(value) as the Sha3_* alias Kekkak_*
or RealSha3_*. This way, we still test all members of the enum,
without duplicating row keys (albeit the aliases duplicate values).

0448d57c07 tst_QBitArray: remove duplicate data rows
Both countBits() and datastream() had two copies of an all-zeros test
with 35 zeros. Removed the second, in each case.

ade68c9949 MSVC: Disable buggy conformance check
/Zc:lambda seems buggy. Although in my experiments it works well
for 99% Qt repos, it seems some tests will trigger the bug and it
also blocks some new commits. So disable it for now, it's not stable
enough.

Now that this check is disabled, the workaround for tst_qstringapisymmetry
is also not needed anymore, so remove the workaround as well.

Partially reverts commit 8cb832090a

b1054d45e9 Fix flakiness in tst_QDoubleSpinBox / editingFinished
setFocus() was called on a double spinbox without calling show()
first. That causes flakiness on XCB when checking focus afterwards.
The test can still fail, when focus is acquired by e.g. a system
popup.

This patch adds a show() call before setFocus() to stabilize normal
behavior. In case the double spin box is shown, but cannot acquire
focus, the test is skipped.

2fd990b386 Port qCompress() to zstream/deflate()
The zlib convenience API we've been using so far has two problems:

- On Windows-64, where sizeof(long) == 4, the use of ulong for sizes
  meant that we could not compress data compressable on other 64-bit
  platforms (Unix). While zstream also uses ulong, being a stream API,
  it allows feeding data in chunks. The total_in and total_out members
  are only required for gzip compression and are otherwise just
  informational. They're unsigned, so their overflow does not cause
  UB. In summary, using zstream + deflate() allows us to compress more
  than 4GiB of data even on Windows-64.

- On all platforms, we always allocated the output buffer in such a
  way as to accommodate the pathological case of random, incompressible
  data, so the output buffer was larger than the input. Using zstream
  + deflate(), we can start with a smaller buffer, then let zlib pick
  up where it left off when it ran out of output buffer space, saving
  memory in the common case that compression meaningfully reduces the
  size. To avoid the first few rounds of reallocations, we continue to
  use zlib's compressBound() for input less than 256KiB.

This completely fixes the compression side of QTBUG-106542 and
QTBUG-104972.

ce950bcbf7 Clean up tst_QAlgorithms::count{Trail,Lead}ing_data_impl()
Pull out the arbitrary factor of three as a named constant and
document its arbitrariness once.

Pull out the mask and bit used in each function's loop to the outer
layer of the loop, since they don't depend on the inner loop variable
(or the random value generated in that loop).

Use QTest::addRow() instead of constructing a string to pass to
newRow().
