But we insist on MinGW debug-and-release builds matching.

439f6c9576 coin: Add instructions to generate docs during testing
A single configuration provides qdoc and qtattributionsscanner via
provisioning. The environment variables instruct QDoc to run in
testing mode; it ignores linking warnings (since we don't have .index
files for external documentation modules) and terminates with non-zero
exit code if documentation warnings exceed the limit set in the
documentation config.

The provisioned binaries are portable, packaged together with their
dependencies. As they are installed under /opt, the instructions
create symlinks to the binaries in the install directory before
building the 'generate_docs' target.

44b7a1a37b Don't hide dialogs before closing them
When a dialog was accepted or rejected via done(), we used to only hide
it, but as of 0246bfd40a we now close it.

Closing a widget results in hiding it as part of handleClose, so we
do not need to explicitly hide it before calling close(). In fact
doing so prevents the lastWindowClosed logic from checking whether
the window was visible before handling the close event, which is
documented to be a requirement for a window triggering lastWindowClosed.

We still need to hide the widget in case we don't end up closing it
ourselves, to ensure QDialog::closeEvent accepts the close. The reason
for the code in closeEvent seems a bit dubious, but that's left for
future adventures.

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.

writing directions, prioritise the script item that has the same direction
as the paragraph (i.e. the QTextEngine) when deciding where and how to

unchanged.

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
  qt-project!          0x0000018f       Unknown note type: (0x74510001)
   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" ?).

3007050db7 macOS: Pass on mouse press if input context didn't handle it
We follow the approach of [NSTextView mouseDown:] by bailing out if the
input context handled the event, and otherwise passing it along to the
input item.

This allows moving the cursor with a single click in the input item,
which will also commit the current preedit string as is, depending on
the input context.

For some reason 2-Set Korean input results in plain insertText calls
for each step of the composition with an NSTextView, while we get
marked text. The result is that when composing with 2-Set Korean,
a native NSTextView will only require a single click to move the
cursor, while for us it requires two, since the input context says
it handled the event.

We opt to follow the behavior of NSTextView to bail out if the
input context handled the event, instead of trying to emulate
the observed behavior for 2-Set Korean by always passing the
mouse event on, as the former seems like a safer approach.

This is also in line with the recommendations from Apple:

c67f46877c macOS: Only send mouse press to input context if clicking input item
Our QNSView can represent many controls, not just the current input item,
so we need to ensure the click happens inside the input item before we
ask the input context to handle the event.

This allows clicking controls such as buttons and check boxes while
composing complex text, without cancelling or otherwise affecting
the composition.

1dfc74970c Deduplicate lastWindowClosed handling
Whenever a window was closed, we had logic to check if it was the last
window, and if so emitted lastWindowClosed and then tried to quit the
application. But the automatic quit process also checked if there were
any remaining windows, as this process could be triggered as a result
of a QEventLoopLocker going out of scope. The two paths now share the
same logic for determining if there are any remaining windows.

The docs have been updated to reflect the original intent of the logic,
dealing only with primary windows (top levels without a transient parent).
This was how both the original code paths implemented their logic.

For historical reasons the Qt::WA_QuitOnClose attribute is closely
tied to the lastWindowClosed signal, and isn't merely limited to
controlling whether we try an automatic quit when the last window
closes. For now this behavior has been kept, but the docs have been
updated to clarify how the attribute is handled in practice.

b6cbd9c43a QList: deprecate iterator<->pointer implicit conversions (2/3)
The constructor from a raw pointer should be
1) constexpr,
2) explicit, and
3) *private*.

We can do 1) without too much trouble.

2) is a (easy to fix) SIC in case of implicit conversions accidentally
relied upon from somewhere.

3) cannot be "easily" fixed by user code (they have to refactor), and
also, it's a BIC on Windows which encodes class members' access in
symbols. Someone may have been exporting some QList subclass, in turn
exporting the iterator classes, and therefore that someone now has the
constructors' symbols with a given access.

So, don't do 2+3 _just yet_ for user code, but set a deadline: Qt 6.5 is
the last that will support this. On Qt 6.6, we switch. All of this on
non-Windows, againt to avoid an ABI break. One can opt-in at any time
via a suitable define.

Given we have this define, use it to guard the other way around as well:
conversions from an iterator to a raw pointer should never be explicit
(there's std::to_address for this).

[ChangeLog][QtCore][QList] Converting a QList's iterator from and to a
raw pointer is deprecated, and will get removed in Qt 6.6. User code can
prepare for the change by defining QT_STRICT_QLIST_ITERATORS.

0220484329 QList: deprecate iterator<->pointer implicit conversions (1/3)
QList<T>::(const_)iterator both feature an implicit operator T*.

This operator exists in order to keep compatibility with Qt 5 code,
where QVector<T>::iterator _was_ indeed a T*. However, iterators are
not proxy objects and should not convert to T* (at least, not
implictly). In fact we've already seen compilers complain about
ambiguous calls when e.g. moving an iterator through an arithmetic
operation (say, operator+).

For instance, if one does

  it + number

and the numeric argument of that call is not precisely qsizetype
(but, say, int), then the call is ambiguous between

  operator+(iterator, int promoted to qsizetype)
  operator+(pointer (converted from iterator), int)

One can imagine similar failures in generic code. In short: let's
deprecate (not remove) the implicit conversion, and let people use
iterators for what they are.

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.

dedb29cf23 Fix high DPI position of foreign child windows on Windows
Suppose you have a child window that is a foreign window.  In the bug
report's example it's a QAxWidget that wraps the Windows Media Player.

This means, we have a non-top-level QWindow with a platformWindow
assigned.  If windows:dpiawareness is set to 1 (system-DPI aware) and
the window is displayed on a screen with origin != (0, 0), then we
called QPlatformWindow::setGeometry with a position in native
coordinates.  This moved the child window outside of the visible area.

Fix this by calling QHighDpi::toNativeWindowGeometry instead of
QHighDpi::toNativePixels.  The former function takes child windows
properly into account.

aad4158959 CMake: Postpone target existence check for qml plugin targets
Each included qml Qt6FooPluginTargets.cmake file checks whether
all the dependency targets that are referenced in the file already
exist by the time the file is included.

If one of the referenced targets is missing, the file sets
${CMAKE_FIND_PACKAGE_NAME}_NOT_FOUND_MESSAGE with a message mentioning
which targets are missing and also sets
${CMAKE_FIND_PACKAGE_NAME}_FOUND to FALSE.

All our qml package Config.cmake and Targets.cmake files are
include()d by Qt6QmlPlugins.cmake using a file(GLOB) which means the
order in which the files are loaded is implementation-defined.

Furthermore we didn't check the above set variables after each
inclusion, which means the values are overridden and the last plugin
to be loaded determines whether the Qml package is found or not.
If the last included file sets no error, it effectively silences any
previously set error.

Ever since we added dependencies between the qml plugin targets
themselves, we hit the above situation and depending on the platform,
no error was shown because the last file overrode any errors.

But we finally got a specific platform (wasm) which unearthed the
problem (QTBUG-97478). This can happen for any static Qt build though.

To fix this properly, we will most likely have to rewrite the whole
inclusion mechanism to use find_package() so that dependencies
can be resolved recursively as needed. This is a non-trivial change
that will have to be addressed in both qtbase and qtdeclarative.

In the mean time, a stop-gap solution that this change implements is
to include all the files while ignoring any error messages.
Then include the files one more time and check for error message after
each included file.

All qml plugin targets should have been brought into scope with the
first round of inclusions, thus circumventing "missing referenced
target" errors, while still catching any other possible errors.
