26267ef57e tst_QHash: Update the erase_edge_case test
By using the bucketForHash function we can loop through and find
some appropriate keys to test the edge-case. This will then
automatically keep the test working even if some internals
of QHash changes.

We do this because certain changes which change the bucket the
pre-selected keys would end up in could make the test a no-op,
without warning. And recent and upcoming changes have changed
both this and erase(). We limit the search-space to
the minimum numBuckets * 4, where minimum numBuckets is current
128.

b1938e5787 tst_QByteArray: fix UB (signed overflow)
The first case is simple, as it's a static overflow. Theoretically,
the compiler would be allowed to just remove the complete function as
dead code. This is an error left from the port from int to qsizetype:
Qt 5.15 there has uint(MaxAllocSize) + 1, so use quint here again,
qint64 is wrong.

In the second case, we _may_ reach alloc == MaxAllocSize. Check that,
if we do, we don't then add 1 to it.

d1626ca6b0 Fix hash lookup using the value of a key iterator
QHash::operator[] could grow the hash even if the key being
looked up already existed. This in turn invalidated all iterators.
Avoid this by refactoring findOrInsert() to not grow if the key
already exists.

Added advantage is that this should make lookups of existing keys
slightly faster.

81bf3e68b9 Make QRingBuffer a move-only type
There's no sense in copying a ring buffer. Moving is enough. This
marks an important step on the way to preventing accidental copies of
ring buffer content, because the 'QList buffers' member can now no
longer be implicitly shared. While the compiler will still emit the
code for detach()ing, it will now never be executed.

ae6dc7d6df Fix qt_scrollRectInImage when scrolling outside of the image
We were clipping the source rect to the image, both pre and post
scrolling, but did not apply the same logic to the target position.
By computing the target position based on the already clipped source
rect we ensure that the target position is also correct.

This was causing valgrind warnings on Linux, and crashes on Windows,
when trying to test the lower level QBackingStore::scroll() function.
The reason we were not seeing this in practice was that QWidget does
its own sanitation and clipping of the arguments before passing them
on.

As a drive-by, fix the access of image to use constBits instead of a
manual cast, and rename variables to better reflect their use.

1c24b4b8d9 Match up testlib selftest's lists of generated files
The actual files present for expected data, the test function that
selected which tests to skip and the python function to select which
to not generate data for weren't in sync with one another.

The test-code's reason for omitting three tests was that we lacked
data files for them. So generate those and skip that exception. The
generator script's code to decide which to generate didn't exclude
anything like as many, so update it to match the test-code. In the
process, save repeating a startswith test that was used both
positively and negatively, unifying two conditions.

Extend the generator script's handling of its --skip-callgrind option
by auto-setting that option if valgrind isn't available, to match the
driver program's similar skipping.

The generated data included many files for tests we skip and, as
mentioned already, lacked files for some tests we only skipped because
we lacked them. Remove the unused files, add the lacking ones.

Reworked various testlib selftests that were using QTEST_MAIN_IMPL();
change to use the new QTEST_MAIN_WRAPPER() and TEST_MAIN_SETUP().
These might be better dealt with by supporting a second form of the
initMain() test-setup function in the test classes, that takes
references for argc and argv, to let a test massage its command-line
options.

93830d9ed3 Fix x86 preprocessor check in testlib selftests
When deciding whether to run benchlibcallbrind, the code only tested
_i386; it now tests __x86_64 as well, to match a recent change in the
test itself. As there, reverse the test to reduce negations, flipping
the stanzas it selects between. Also tidy up the code that tests for
valgrind being present - and actually return true, to skip the test,
when it claims to be skipping the test.

Updated test results, now that the test can actually be run and
produce sensible output. Added an _2.txt that matches the results
presently seen in Coin on RHEL 8.4 (despite the fact that a local
build on such a VM produces output matching the _1.txt results).

e42fe5c775 Fix argv hacking in tst_benchlibcallgrind.cpp
It unconditionally added -callgrind to its own command-line options,
but the way testlib handles this argument is, in QTest::qRun(), to
re-run the program under the control of valgrind --tool=callgrind,
removing the -callgrind command-line option from the test and adding
-callgrindchild to its command-line options. So we shouldn't re-add
the -callgrind option in the resulting recursive call.

The test now runs quickly, producing sensible output, where previously
it took a very long time. Revised the drivers to reflect this
speed-up, but continue skipping the non-.txt formats to save the need
for variant-output files for many formats. To match that, removed the
unused non-.txt results files.

e297e80fd0 QVarLengthArray: make reallocation strongly exception safe
The old code had several bugs:

- it immediately clobbered *this with new state, before having copied
  over the elements from the old to the new buffer

- when buffer relocation threw, it would keep the new (partially-filled)
  buffer and throw away the old

- it unconditionally used std::move() for non-relocatable types, making
  it impossible to restore the original buffer when a move throws

Instead of clobbering *this with new state, do all the work on the
side and change *this only once the reallocation has happened
successfully.

Also use q_uninitialized_relocate_n() and unique_ptr in the
implementation to simplify the code. The former got the necessary
update to use std::move_if_noexcept() instead of an unconditional
std::move() for the non-relocatable case.

[ChangeLog][QtCore][QVarLengthArray] The append()-like functions are
now strongly exception safe. This means reallocation will now use
copies instead of moves, unless the value_type has a noexcept move
constructor.

4f53c703e4 QLocale: Extend support for language codes
This commit extends functionality for QLocale::codeToLanguage()
and QLocale::languageToCode() by adding an additional argument
that allows selection of the ISO 639 code-set to consider for
those operations.

The following ISO 639 codes are supported:
    * Part 1
    * Part 2 bibliographic
    * Part 2 terminological
    * Part 3

As a result of this change the codeToLanguage() overload without
the additional argument now returns a Language value if it matches
any know code. Previously a valid language was returned only if
the function argument matched the first code defined for that
language from the above list.

[ChangeLog][QtCore][QLocale] Added overloads for codeToLanguage()
and languageToCode() that support specifying which ISO 639 codes
to consider.

84fba93ebb QThread::create(): request interruption and join on destruction
If one destroys a running QThread, so far the behavior has been to crash
(à la std::thread) -- assuming the thread hasn't already signalled that
it has finished. This behavior is hostile to solutions such as using
QThread::create(), which always require a wait() before destroying the
thread object.

We can use the opportunity to change the behavior without breaking any
valid code. Instead of crashing, inside QThread's destructor we can ask
the new thread to quit, and then join it (à la std::jthread). This
simplifies the implementation of long-living runnables and the code that
manages them.

Deploying this solution for the whole QThread class may not be entirely
painless. While no correct code would work differently with the proposed
changes, incorrect code that deletes a running thread would no longer
crash "loudly" -- instead, it might deadlock "quietly", have memory
corruptions, etc.

Hence I'm limiting this approach to only the threads created by
QThread::create(), at least for the time being. This also side-steps
perhaps the biggest problem of generalizing the approach, which is that
placing such interrupt+join logic into~QThread's destructor would cause
it to be run _after_ a QThread subclass' own destructor has run,
destroying the subclass' data members too early. This might create
an antipattern if one chooses to subclass QThread. With create(), a
subclass in question exists, and it indeed has NSDMs, but it's entirely
under our control (in fact, I'm placing the logic just in its dtor).

[ChangeLog][QtCore][QThread] Destroying a QThread object created by
QThread::create() while the thread that it manages is still running will
now automatically ask that thread to quit, and will wait until the
thread has finished. Before, this resulted in a program crash. See the
documentation of QThread::~QThread() for more details.

d797e3c88e Optimize QMimeDatabase::mimeTypeForFile(f, MatchDefault)
Open the file only if matching on content is needed.

Use QFileInfo::filePath() instead of QFileInfo::absoluteFilePath() in
QMimeDatabase::mimeTypeForFile(). filePath() does much less work, and so
is faster. Thiago Macieira helpfully explained in a review comment why
the absolute path is not useful for correctness here: "Nothing needs
absolute paths within the same application that would resolve the
relative path to absolute. You only need an absolute path if you're
communicating with another application that may be in a different
directory."

QMimeDatabase::mimeTypeForFile() checks fileInfo.isDir(), so the
fileName.endsWith(QLatin1Char('/')) check in
QMimeDatabasePrivate::mimeTypeForFileNameAndData() was redundant when
called from this function. The other two callers of that function now
check this condition before opening IO devices. This improves
performance of the two QMimeDatabase::mimeTypeForFileNameAndData()
overloads in the corner case.

Refactor and optimize QMimeDatabasePrivate::findByFileName() and its
usages. Previously each caller constructed a QFileInfo object and passed
QFileInfo::fileName() into this function. Now the callers simply pass an
absolute or relative path to a file into this function, which then uses
QFileSystemEntry::fileName() to exclude the path. Constructing QFileInfo
is relatively expensive, so this change slightly improves performance.

Optimize QMimeDatabasePrivate::loadProviders() by calling static
QFileInfo::exists() instead of constructing a QFileInfo object and
calling the non-static QFileInfo::exists() overload. Note that the
QFileInfo object was always created, even if QFileInfo::exists() under
an `if` and an `#if` was never called.

After the windows font engine was no longer marking everything as
scalable we started limiting the font size of requests to the maximum
of Courier when it was requested. This was a regression from 5.8 and not
in agreement with our documentation.

The problem is that we would only make the switch from Courier to
Courier New after having already gone through the foundry-lookup and
found a closest-available font size for Courier.

With this sanitization step in the backend we can make these changes
early enough that we haven't yet adjusted e.g. the font size.

56bd1b76d2 Don't change resolve mask when setting brush doesn't change palette
After 556511f9f3, which moved the resolve
mask storage into the palette's d-pointer, modifying the resolve mask
requires a detach. As of now, we only detached when setting a different
brush, but always modified the resolve mask, which broke palettes that
shared the d-pointer (likely the global default palette).

However, detaching has negative side effects when styles set brushes on
temporary palette objects and then use that palette object's cache key
to build a cache of pixmaps. As each drawing would detach the palette
(even if the palette doesn't change, which is likely), the cache key
changes with each detach, and the cache would quickly increase in size.
This was addressed in changes d7bcdc3a44
and 1e75dcf251.

We can either detach and find other ways to address the issues from
QTBUG-65475, or we can not change the resolve mask when the brush doesn't
change and completely ignore the call.

Since QFont ignores the setting of any attribute to a value that is
identical to the current value, and since it's possible to force that
the resolve-bit is set by calling setBrush twice with different brushes,
ignoring the call seems like the better solution.

[ChangeLog][QtGui][QPalette] Setting a brush on a palette that is
identical to the current brush no longer sets the resolve mask bit for
that particular role, so items using the palette will continue to
inherit changes from parent items.

c034ad03ac QPA: Set focus reason when window activation changes focus
QApplication hides the fact that the reason is never set by several

Add relevant scenario to the QFocusEvent test case, and fix the
plugins to always set the focus reason when handling window activation

dbb9579566 Text editing: smart block and char format after newline
When you are editing in a QTextEdit and press enter to start a new line,
calling insertBlock() with no arguments tries to preserve the current
charFormat and blockFormat. That is often OK:
- if you hit enter at the end of a list item, you probably want another
  item in the same list
- if you are writing code inside a code block, you're probably just
  writing the next statement on the next line: stay in the same block
- margins, indents, tab positions should stay the same (but hopefully
  your editor has UI to manually reset the block format to default
  in case you are not continuing in the same style)
But there are some exceptions we can apply to be helpful:
- nobody ever wants to follow an <hr/> with another one (but
  hopefully the application has an action to insert one manually)
- a heading is more likely to be followed by a paragraph, or perhaps
  a smaller heading; another heading at the same level is unlikely.
  We need to reset the char format, not only the block format, because
  the large font and heavy font weight are stored there.
- when adding to a todo list, hitting enter at the end of the last task,
  let's assume the next task is not yet done, so it will be unchecked
  by default (else, why are you writing a todo list at all)
To achieve that, we need to customize the formats and call the
insertBlock() overload that takes them. The no-argument insertBlock()
will continue to preserve the formats, because it's an old API that is
used for much more than interactive editing.

Additionally, word processors tend to let you end a list (for example)
by hitting enter twice. In that case, you stay in the same paragraph
that you created the first time you hit enter, but now the formats are
reset to default, so that you can go on typing an ordinary paragraph,
rather than having to mouse up to the toolbar to select the paragraph
style in a combobox, or something like that. So we now do that: reset
both block and char formats after you hit enter on a blank line; but if
you then hit enter again, after the block format has been reset, then
you will get the actual blank line (empty block) inserted.

[ChangeLog][QtWidgets][QTextEdit] Hitting enter at the end of a line
with a special block format (horizontal rule, heading, checklist item)
now makes some "smart" adjustments to avoid retaining properties that
are unlikely to be continued on the next line. Hitting enter twice now
resets block and char formats to default.

6b02473e1e Fix overlapping text for Osaka font on macOS

because it is not intended to be cross-platform. In Qt 6 (since
f761ad3cd9) we are trying using the
same vertical metrics on all platforms, but this only works if
they are valid.

To work around this issue, we detect the case when ascent/descent
values are both 0, since this is very unlikely to be intentional,
so we fall back to the system-provided ascent and descent in these
cases.

Adding the test also revealed that we had missed the check for
a macOS-specific bitmap font format when skipping the check for

In particular, it makes impossible passing lambdas that are capturing

54536bb5ae QString::arg: deprecate use of arbitrary Unicode digits as replacements
The only documented replacements for Q*String*::arg() are sequences like
%1, %2, %3 -- where the n-th number is expressed using a sequence of
ASCII digits [1].

The code parsing the replacements however used the QChar::digitValue()
function. That function simply checks if a QChar has a *Unicode digit
value* (no matter what its block/category is), and if so, returns the
corresponding digit value as an int (otherwise returns -1).

The result of this is that a sequence like "%¹" or "%१" actually
triggered substitutions (both count as "1"). Similarly, QChars with
a digit value would be parsed as part of longer sequences like "%1²"
(counting as "12" (!)).

This behavior is weird, undocumented, and extremely likely the usual
backstabbing by Unicode by using "convenience" QChar methods -- that is,
never *intended* by the implementation.

This commit deprecates (via warnings) such usages, which for the time
being are left working as before (in the name of backwards
compatibility). At the same time: given it's extremely unlikely that
someone would be deliberately relying on this behavior, it implements
the desired change of behavior (only accept sequences of ASCII digits)
starting from Qt 6.6, that is, after the next LTS.

Throughout Qt 6's lifetime users will still be able to control arg()'s
behavior by setting an env variable, but that variable (and the support
for Unicode digits) will disappear in Qt 7.

To summarize:

* Qt 6.3->6.5: default is Unicode digits, env var to control
* Qt 6.6->6.x: default is ASCII digits, env var to control
* Qt 7: only ASCII digits, no env var

[1] That's the name Unicode gives to them, cf. https://www.unicode.org/charts/PDF/U0000.pdf

[ChangeLog][QtCore][Deprecation Notices] The arg() functions
featured in Qt string classes have always been documented to require
replacements tokens to be sequences of ASCII digits (like %1, %2, %34,
and so on). A coding oversight made it accept sequences of arbitrary
characters with a Unicode digit value instead. For instance, "%2੩" is
interpreted as the 23rd substitution; and "%1²" is interpreted as the
12th substitution. This behavior is deprecated, and will result in
runtime warnings. Starting from Qt 6.6, arg()'s behavior will be changed
to accept only ASCII digits by default. That means that "%1²" is going
to be interpreted as substitution number 1 followed by the "²" character
(which does not get substituted, so it gets left as-is in the result).
Users can restore the previous semantics (accept Unicode digits) by
setting the QT_USE_UNICODE_DIGIT_VALUES_IN_STRING_ARG environment
variable to a non-zero value. In Qt 7, arg() will only support sequences
of ASCII digits. Note that from Qt 6.3 users can also set
QT_USE_UNICODE_DIGIT_VALUES_IN_STRING_ARG to zero; this will make arg()
use ASCII digits only, in preparation for the future change of defaults.

0e72a846d3 QObject: Q_ASSERT the object type before calling a PMF
The old-syle signal-slot syntax had the advantage of not delivering
signals to slots in derived classes after that derived class's
destructor had finished running (because we called via the virtual

old to the new syntax may introduce crashes or other data corruptions at
runtime if the destructor had completed.

This commit introduces a Q_ASSERT to print the class name that the
object is not any more. Since this is in inline code, this should get
enabled for users' debug modes and does not therefore depend on Qt being
built in debug mode.

It required some Private classes to be adapted to the new form, by

works for value classes (the Q_GADGET audience), it is not desirable

c27d2a57a4 Make QAbstractProxyModel itemData() behave like data()
QAbstractProxyModel::itemData/setItemData should behave
just like data()/setData() instead of calling the
QAbstractItemModel implementation.
Before this change the QAbstractProxyModel implementation
calls its the QAbstractItemModel implementation,
which ends up calling data()/setData() in a loop
bypassing the convenience of itemData/setItemData.

[ChangeLog][QtCore][QAbstractProxyModel] The itemData()
and setItemData() functions will now call the respective
implementations in the source model (after mapping the
index to a source index), matching what data() and
setData() already did.
Before, the proxy model simply called the default
implementations of itemData()/setItemData() in its own
base class (QAbstractItemModel).

8c9875893b Q(Multi)Map: prevent dangling key/value after detach()
Q(Multi)Map mutating functions that take reference to a key and/or a
value (e.g. insert(), take(), etc.) must make sure that those references
are still valid -- that is, that the referred objects are still alive --
after the detach() call done inside those functions.

In fact, if the key/value are references into *this, one must take extra
steps in order to preserve them across the detach().

Consider the scenario where one has two shallow copies of QMap, each
accessed by a different thread, and each thread calls a mutating
function on its copy, using a reference into the map (e.g.
map.take(map.firstKey())). Let's call the shared payload of this QMap
SP, with its refcount of 2; it's important to note that the argument
(call it A) passed to the mutating function belongs to SP.

Each thread may then find the reference count to be different than 1 and
therefore do a detach() from inside the mutating function. Then this
could happen:

Thread 1:                         Thread 2:

detach()                          detach()
  SP refcount != 1 => true          SP refcount != 1 => true
    deep copy from SP                 deep copy from SP
    ref() the new copy                ref() the new copy
  SP.deref() => 1 => don't dealloc SP
  set the new copy as payload
                                    SP.deref() => 0 => dealloc SP
                                    set the new copy as payload

  use A to access the new copy      use A to access the new copy

The order of ref()/deref() SP and the new copy in each thread doesn't
really matter here. What really matters is that SP has been destroyed
and that means A is a danging reference.

Fix this by keeping SP alive in the mutating functions before doing a
detach(). This can simply be realized by taking a local copy of the map
from within such functions.

remove() doesn't suffer from this because its implementation doesn't do
a bare detach() but something slightly smarter.

71faedc5b4 Fix deserializing Qt 5.x fonts through QDataStream
In Qt 5, fonts had both singular family and plural families properties,
and both were stored separately when streaming through QDataStream. The
families list was treated as an extension of family in this case, and
the primary font family was always the singular family property.

In Qt 6, it has been merged into one and family() is now just a
convenience for families().at(0).

But when reading files generated with Qt 5, we would ignore the fact
that these were previously separated. We would first read the family
entry into the families list, and then we would later overwrite this
with  an empty families list.

Instead, we detect streams created with Qt 5.15 or lower and make sure
we append the families list instead of overwriting it in this case. In
addition, we need to make sure we split up the list again when
outputting to Qt 5.x.

This adds a file generated with QDataStream in Qt 5.15 to the test to
verify.

that had been serialized using QDataStream in Qt 5.

79b2a43585 Add baseline test that allows comparing the rendering of widgets
Provide basic boiler plate that sets up the baseline (aka lancelot)
framework specifically for comparing the appearance of widgets, and
implement test functions for QSlider and QPushButton.

Widgets should always look the same if the QPA platform, the OS
version, and certain UI-impacting attributes are identical. Ie.
on any macOS 10.15 machine that runs in "Light" mode, widgets
look the same. On a macOS 11 machine, they might look different.
On an OpenSUSE machine using the fusion style things might look
different from a Ubuntu machine.

The helper function removes DPR differences - images are always
scaled to a DPR of 1.0, which allows us to compare the image\
content and not get distracted by them having different dimensions
(and the fuzzy comparison of images might make the system tolerate

Note: For now, this test is meant to be run locally, either when
testing changes to style code, or when checking how QWidget based
UIs would look on newer version of an operating system. In CI the
test is run, but then skipped in CI as the baseline server is
not configured.

In preparation for addition of new baseline tests, establish a new
test category, "baseline". This is similar to the category
"benchmarks" in that it contains tests that use the QTest framework,
but conceptually are not unit tests, in contrast to those under auto/.

Move the existing QPainter baseline test, tst_lancelot, into this new
category, and rename it accordingly.

Baseline tests use the QBaselineTest extension to QTest. Move that
extension too into the tests/baseline directory, allowing the clean

22634e0079 Make sure we paint overlapped children and siblings when moving far
In paintAndFlush, QWidgetRepaintManager subtracts opaque children if
the target isn't overlapped and isMoved is set to true. So in moveRect,
set isMoved to true after the blitting of movable areas, and reset it to
false if we have overlapped sibling or child regions. Otherwise, moving
so far that sourceRect is invalid (none of the original pixels are
visible after the move) we end up in a code path that sets isMoved to
true even with overlapping children or siblings, which then breaks
paintAndFlush's assumptions.

QTabBar implements wheelEvent to move the current index up or down. This

Instead, scroll the entire tab bar when the wheel event comes from a

As drive-by's, fix the test introduced in aa09bea00c to
not leak memory or leave a test-specific style set on the QApplication
instance, which can break other tests.
Also, make relevant layout code in QTabBar respect the usesScrollButtons

5fc9c02a69 QProcess: Distinguish between null and empty QProcessEnvironment
The documentation for QProcessEnvironment's default constructor
says:

    This constructor creates an empty environment. If set on a
    QProcess, this will cause the current environment variables
    to be removed.

This is not the case however, because setting such an environment
for a process is equivalent to not setting an environment at all
and the child process is executed with parent's environment.

It is still possible starting from Qt 6.2.0 to create an empty
environment by adding a variable to a null environment and removing
it, but that's cumbersome, and the comparison operator says that
it is equal to the null environment but it is obviously behaving in
a different way.

This change adds an additional constructor to QProcessEnvironment
that can be used to construct a null environment, and changes the
default constructor to produce an empty environment. The comparison
operator is changed to correctly distinguish between such objects.
This is a behavior change, but the current behavior is broken
and this is unlikely to affect working code.

[ChangeLog][QtCore][QProcessEnvironment] An additional constructor
was added to explicitly create an object that when set on QProcess
would cause it to inherit the environment from parent (this was
formerly the behavior of a default-constructed QProcessEnvironment,
which will now (as documented) actually give a process an environment
with no variables set). A new method inheritsFromParent() was added
to test for such objects.

02164b292f Don't use QCursor::pos in QTabBar and fix hover handling
Relying on QCursor::pos makes tests fragile and prevents multi-seat support.
Instead, record the mouse position in the already existing event handling,
and use that instead. Styles might use either WA_Hover or enable mouse
tracking for the widget to enable hover-effects, so we need to support both.
Fix the scenario where a newly inserted tab ends up under the mouse, which
was previously not handled correctly (only the case of removing a tab was).

Clean up the repaint management when the hovered tab changes; just call
update on the old rect, and then later update on the new rect; there's no
need to make a copy first, updates are posted and compressed.

Add a unit test that makes sure that we paint tabs that should be under the
mouse in the hovered state. Since not all styles enable hovering and/or
mouse tracking in all cases, use a style sheet for those styles that don't.

f5fbad669d QByteArrayList: add join(QByteArrayView)
Since QByteArray/QByteArrayView don't overload nicely, we need to make
the existing QByteArray overload a Q_WEAK_OVERLOAD (= a template) as a
tie breaker. This automatically prefers the QByteArrayView version
over the QByteArray overload, transparently optimizing existing users
passing char string literals to avoid the implicit creation of a
QByteArray just for passing the separator.

None of our modules exports a subclass of QByteArrayList, so turning
join(QByteArray) into a function template should be ok.

[ChangeLog][QtCore][QByteArrayList] Added join(QByteArrayView)
overload.

Note that currently it is not possible to expose only a slice of the

Antialiasing is disabled when the painter's antialiasing attribute

antialiasing state of the clipping region is not updated after the
antialiasing attribute is set.

A variable is required to record the painter's transformation state
set before the clipping function, because the transformation will be
applied to the clipping region, resulting in the abnormal clipping
region. The value of `s->matrix` is not accurate for the clipping fun-

71aaf831d1 QAbstractItemView: auto-scroll with selection rectangle
Some item views, such as QListView in icon mode, implement a selection
rectangle with which the user can "lasso" items. So far, dragging that
rectangle did not trigger auto scroll, so unless an item near the edge
was selected, the user had to stop the lassoing and scroll manually to
reach more items.

Since QAbtractItemView implements auto scrolling for drag'n'drop, we can
use that mechanism also when the selection rectangle is dragged. This
requires some modifications:

We need to make sure that scrolling the view during a drag-selection
generates mouse move events so that the selection is extended and the
rectangle is updated in subclasses.
And we need to stop using QCursor::pos to get the position of the mouse
pointer, as this makes the auto-scrolling untestable. Instead, record
the mouse position last seen during a mouseMove or dragMoveEvent in
content-coordinates (identical to pressedPosition).

As a drive-by, fix some coding-style issues in nearby code.

Instead of plumbing QWidgetWindow close events via handleCloseEvent,
we just implement closeEvent directly. This allows QWindow do save

know whether we should trigger lastWindowClosed handling, even if
the window was deleted as a result of the close event.

This also relieves QGuiApplication and QApplication from dealing
with the close logic in their notify functions, so that these
functions can focus on the propagation of events -- not how the
event is handled.

a9d51298ae Fix metatype declaration for QHash/QMultiHash with no operator==
When declaring metatypes, the metatype system tries to detect if the
comparison operators for the given type exist and automatically register
them. In case of QHash, the equality operator was enabled if the value
type provides one. But the implementation needs equality operator of
the key type as well. As a result, when the key type has no equality
operator, the metatype system detects that the equality operator is
available for the QHash itself, but the compilation for metatype
registration fails when trying to instantiate the code that uses
equality operator for the key. This is fixed by enabling equality
operators for the QHash only when both the key and value types provide
one.

The same issue existed also for QMultiHash, with the difference, that
QMultiHash didn't have the constraints even on the value type. So added
checks for both.

df359bcb70 Decouple quitOnLastWindowClosed from quitLockEnabled
In a512e210ac5b032c5fc2edf1ddf72e5a414485fda512e21 quitOnLastWindowClosed
was changed to be implemented in terms of quitLockEnabled, but without
any documentation to that end.

Although the two features are similar (automatic quit under certain
conditions), and interact, it doesn't make sense to overlap them until
we actually expose them as a single property (automaticQuit e.g.)

The logic for determining whether we can can quit automatically has
been refactored to take both properties into account, on both a Core
and Gui level. The call sites still need to check the individual
properties to determine whether to activate automatic quit for
that particular code path.

f54044d4a9 Fix cursor placement at left and right ends of bidi text
In a text line that has a change of direction at either end of the text,
the cursor needs to be positioned where the next character is inserted,
or where backspace deletes the previous character. In bidi text, this is
ambiguous as illustrated by this example:

abcشزذ

Depending on whether this string was typed in a left-to-right document
or in a right-to-left document, it could be first latin, then arabic; or
it could be first arabic, then latin.

If a general left-to-right context, cursor position 0 should be in front
of the 'a', and cursor position 6 should be at the end of the arabic
text, in the visual middle of the line. Cursor position 3 can be either
after the 'c' if the next character typed would be latin, or at the
visual end of the line if the next character will be arabic.

Qt calculated the cursor position past the right end of the text as 3
(which is not wrong, but 3 has two visual positions), and placed the
cursor at the visual end of the line (favoring the right-to-left
alternative). Backspace would then delete the 'c', writing a new
latin character would insert a 'd' next to the 'c', writing a new arabic
character would insert it also in the middle - none of these operations
happen at the visual end of the line, where the cursor was blinking.

To fix this, we take into account the general layout of the text, which
is typically based on the document, or the user's locale setting and UI
translation, and calculate the cursor position accordingly: if we are
past the visual end of the document on either side, then the cursor
position is either 0 or the last character of the text, depending on the
direction of the QTextEngine used. This way, the cursor ends up in the
middle of the document when we click beyond the end of the line, which
is where characters are removed and inserted. Typing a 'd' at this point
will make the cursor jump to the end, where the d is added.

There are still corner cases: clicking on the right-most arabic character
calculates the cursor position as 3, which is then ambiguous, as it can
be either at the visual end of the string, or next to the 'c'. َQt makes
the inconsistent choice to place the cursor at the visual end, showing
the left-to-right indicator, but pressing a 'd' adds the 'd' after the
'c' in the middle of the text.

8c2969ea86 QPlugin: Move the plugin metadata to a note in ELF platforms
A few systems, like OpenWRT, may strip the section table off the
resulting binaries (see [1]), making it impossible for us to pinpoint
the exact location of the Qt plugin metadata. This commit moves the meta
data to a location that is identifiable even in fully stripped binaries:
an ELF note.

By naming our section ".note.qt.metadata", we instruct the linker to
place it along the other notes and to mark it in the program header
section. Another advantage is that the notes are usually in the very
beginning of the file, as they are used by the dynamic linker itself, so
we'll need to read much less of the full contents.

The unit test is modified not to attempt to strip the plugin of
debugging data. In fact, we add something to the end that would,
otherwise, be matched as (invalid) metadata.

The following was produced with GCC 11 and GNU binutils ld 2.36.1.

Section Headers:

The Qt metadata note is 4-byte aligned and can thus be found in the
second note section, which spans from 0x02d8 to 0x02d8+0xac=0x0384.

GNU readelf -n can even show it:

Displaying notes found in: .note.qt.metadata
  Owner                Data size        Description

   description data: 01 06 03 81 bf ...... ff

I chose 0x7451 as the prefix for our notes, even though they're already
namespaced by the owner in the first place, because eu-readelf
mistakenly tries to interpret note 1 as a GNU ABI tag regardless of
owner. The owner name was chosen to be 12 bytes long, so the ELF note
header is 24 bytes in total. There's no space wasted because the payload
needs to be aligned to 32-bit anyway and I didn't want to use only 4
characters (header total size 16 bytes) so we'd skip the "GNU" note on
size, without string comparison. And I couldn't think of a 4-character
representative string ("QtP" ?).

32edae5e26 Fix restoring main window state for maximized/fullscreen windows
On systems that asynchronously resize the window to maximized or full
screen state, the window will become visible in its normal geometry
before it gets the final size by the windowing system. This might cause
multiple resize events, to each of which the widget's layout responds
with a call to its setGeometry implementation.

The QMainWindowLayout is special in that it will shrink dock widgets if
there is not enough space for them, but it doesn't grow them back once
there is. With the initial resize event being for a smaller size than
what was restored, the state is not restored correctly, but remains in
the state that fit into the smallest size with which setGeometry got
called.

To fix this, we have to keep the restored state around until the window
either gets a size that is large enough for it to fit, or until we can
be reasonably certain that the windowing system is done resizing the
window while transitioning it to the maximized or full screen state.
Since across the various platforms and windowing systems there is no
reliable way to know when the window reaches its final size, we have
to use a timer that we (re)start for each call to setGeometry with a
size that's not large enough. Once the timer times out, we have to
give up; then the last layout state calculated is the final state.

To calculate the size of the layout, introduce a function to the
QDockAreaLayout that returns the size required for the current sizes
of the docks. Refactor sizeHint and minimumSize (which were identical)
into a helper template that takes member-function pointers to call the
respective method from the dock area layout's content items.

Add a test case for various permutations of the scenario. The timeout
of 150ms is based on running this test case repeatedly on various
desktop platforms and X11 window managers.

5e55297ee0 Markdown writer: indent fence consistent with code block

- But it's also ok *not* to indent (and github handles that better):
```
int main() ...
```
- There was a bug that when the code is not indented, the fence would be
  indented anyway:
  ```
int main() ...
  ```
  and that was not OK, neither for md4c nor for github.

Now with this change, either way is rewritable: you can read markdown
into QTextDocument, make small edits and write it back out again, with
the indentation being preserved (the code block is either part of the
list item, thus indented, or else it's outside the list completely).

74e634d82c macOS: Correctly record normalGeometry in Cocoa plugin
Cocoa sends QWidget the state-change notification after the window has
been resized already, at which point we cannot store the normal geometry
anymore.

Handle zoom and full screen callbacks prior to the state changing
to store the geometry in QCocoaWindow. We do not need to handle
minimized state, as the window will still reflect the original
geometry.

Return the stored value from an override of
QPlatformWindow::normalGeometry so that QWidget gets the correct values
even though the new state is already active.

Fix the tst_QWidget::normalGeometry test to make it pass on all
platforms by waiting for the window to actually have transitioned to
the new state before comparing geometries. Both macOS and Windows fully
pass; on Xcb, deminimizing a window using setWindowState does not work,
which is why the test was partially skipped (confirmed by visual
testing). Move those problematic, complex test cases to the end so
that most cases are covered on Xcb as well.

cb0ea39895 CMake: remove support for building Qt with the old Intel compiler
This hasn't worked for some time. It's not in our CI and I don't think
it was working at all. When I tried to build it, I ran into several
problems with C++17 and an Internal Compiler Error I did not have any
interest in working around.

After discussing with the Intel compiler team, it was decided that
fixing those issues in the old compiler is not going to happen. Instead,
their recommendation is to adopt the new LLVM-based compiler, which
the last commit added support for.

This commit does not remove qmake support for the old ICC. It's possible
someone is using qmake with a non-Qt6 project and ICC.

ba23507960 Fix handling of time-zone gap in QTimeZonePrivate::dataForLocalTime()
This was handled correctly when the backend supplies transitions
bracketing the time in question, but the fallback code tried to use
the DST offset at the time with larger offset from UTC; this did not
work when the gap was due to a change in standard time. Discovered by
ANS1 parsing of a date-time with two-digit year, for which the
date-time parser tried to use 1921-05-01T00:00 local time when filling
in the fields it had parsed; but, when run in Europe/Helsinki, there
is no such time due to the 20m 11s skipped when joining EET from the
prior local solar mean time.

Correct the calculation to use the actual change in offset from UTC,
as used in the (far better tested) between-transitions branch of the
code, rather than the DST offset after the transition.

Add a test-case based on the ASN.1 certificate date whose parsing
revealed the issue. Although it seems nothing in Coin can reproduce
the issue, the reporter has verified that the test does indeed fail on
the system where the bug was found and the fix does fix it.

8513bcd90c Fix caching of parsed border color values in CSS parser
When parsing CSS, a border-color value is parsed as four brushes, as css
allows assigning up to four values, one for each side.

When applying the CSS to the HTML, we accessed it as a color value,
which overwrote the parsed value with a QColor. So while we had a valid
parsed value (and didn't re-parse), the code accessing that value still
expected it to be a list, and thus failed to retrieve the data.

There are several ways to fix that, but the cleanest way without
introducing any performance penalty from repeatedly parsing (and in fact
removing a parse of the string into a color) is to enable colorValue to
interpret an already parsed value that is a list without overwriting the
parsed value again. To avoid similar issues in the future, add assert
that the parsed value has the right type in brushValues.

As a drive-by, speed things up further by making use of qMetaTypeId
being constexpr, which allows for it to be used in a switch statement.

Add a test case.

826765f654 Select a single range of cells in QTableView, away from merged cells
- when there is no intersection between the current selection and the
  spans collection, get ranges for all cells, just as if no span exists
- when there is an intersection between the current selection and the
  spans collection, get separate ranges for each cell (as before)

This fixes the regular case of selecting multiple non-spanned cells
after some cells are merged (get a single range for all cells instead of
separate range for each cell). However, when selecting together a group
of spanned and non-spanned cells, you still get a separate range for
each cell. But this is normal behavior in similar applications; for
example in LibreOffice, you cannot select and merge spanned and
non-spanned cells: an error dialog tells you that it's not allowed.

c89286b26a QPlugin: suppress the "QTMETADATA !" magic in static plugins
The .qtmetadata section is already suppressed for static plugins, but we
carried this unnecessary magic string. For library file formats where we
don't have a scanner (Windows COFF PE), a library that linked multiple
static plugins could end up with multiple metadata found.

We can't suppress the header because the version of moc could be
different to the version of Qt, so we need to read the header version
too. Right now, the version isn't output by moc (all the logic is in
qplugin.h), but this could change again in the future. In any case, 4
extra bytes are not a big deal, so the header stays.

44b9aec8d9 QDialog: respect WA_ShowWithoutActivating
QDialog overrides setVisible to set focus on the default push button, or
(if there is no such button), make the first autoDefault push button the
default button. QDialog also explicitly sends a FocusIn event to the
focus widget in the dialog.

All this should not be done if the dialog does not become active after
getting shown, which will be prevented if the WA_ShowWithoutActivating
attribute is set.

6c4dc722cb Reduce the width of a hfw-widget if scrollbar would be flipping
For a widget that implements height-for-width, the vertical scrollbar
becoming visible might be just enough to make the scrollbar unnecessary.
In that situation, the scrollbar flips on and off continuously.

To avoid that situation, make the width of the widget smaller until the
height fits without scrollbar, up to the point where we have space for
the scrollbar anyway.

The calcuation here is assumed to be cheap, but depends on the
heightForWidth implementation in the widget. Running the while-loop a
few dozen times should have no performance impact during resizing
and laying out the scroll area contents.

Add a test that confirms that within a brief period of time we only get
the one hide-event we expect.

e0b6b27d39 Add style hint for preventing spin box selection on up/down
On a mobile device, selecting text in a line edit brings up the text
action popup for select/copy/cut. In a spinbox where the user changes the
value using the buttons, this can be very irritating, without providing
any usability - the user is unlikely to start typing, at least not
without first transferring focus into the lineedit first to bring up the
keyboard.

This style hint allows styles to override the default behavior of
QAbstractSpinBox. Implement the customization for the Android style, and
add a test case for QSpinBox.

[ChangeLog][QtWidgets][QStyle] A new style hint, SH_SpinBox_SelectOnStep,
specifies whether pressing the up/down buttons or keys in a spinbox will
automatically select the text.

911c97f2b5 QCocoaWindow: Make window key if the app's modal window is hidden
On macOS, when showing a window, we decide if it should be made
key and therefore active, if the app has no active modal session
or if the window's worksWhenModal returns true.

However, the window needs to be made key also when a modal window
is present, but not visible. Add this condition when checking if
the window needs to be made key.

This makes the behavior consistent with what happens when a modal
is minimized on macOS. The input focus is passed to the next window,
and the window appears active, even if it can not be interacted with.

51300566ff Fix closing and showing a window with a native child
Closing a window with a native child results in the native child's
QWidgetWindow being closed. That explicitly calls setVisible(false)
on the child, which will still have the ExplicitShowHide attribute
set from the initial (explicit) show. Even though we then reset
the ExplicitShowHide, the WState_Hidden attribute will still be
set, so Qt considers the window to have been hidden, and not show
it again when the parent becomes visible.

46fc01d7ca QElfParser: rewrite using elf.h
This rewrite uses the actual structures supplied by the system's C
library, so it should be easier to read. It removes hardcoded constants
with little evident meaning in favor of sizeof() and the macros from
that header. It also removes advancing the data pointer in favor of
having absolute offsets.

The resulting implementation is stricter than the original, checking
more fields in the header. Because the QPluginLoader and QFactoryLoader
users may make decisions based on availability of plugins before
attempting to load them, it's better to be stricter here than to fail
later when trying to dlopen() them.

Debugging and testing are much improved. Instead of stored artifacts, I
added a routine to modify a valid plugin to make it invalid, given the
conditions we've found so far.

If you turn debugging on for this category, you'll see things like:
