All these TUs relied on transitive includes of qpointer.h, maybe to a
large extent via qevent.h, though, given that qevent.h is more or less
the only public QtBase header that includes qpointer.h, something else
seems to be at play here.
Said qevent.h actually needs QPointer in-name-only, so a forward
declaration would suffice. Prepare for qevent.h dropping the include.
The algorithm I used was:
If the TU mentions 'passiveGrabbers', the name of the QEvent function
that returns QPointers, and the TU doesn't have qpointer.h included
explicitly, include it. That may produce False Positives, but better
safe than sorry. Otherwise, in src/, add an include to all source and
header files which mention QPointer. Exception: if foo.h of a foo.cpp
already includes it, don't include again.

This changes takes Qt for Android Java code away from the Delegate
classes that uses heavily Java reflection to invoke Activity/Service
calls and overrides. So instead of that, now, we have a QtActivityBase
and a QtServiceBase classes which handle the override logic needed for
Qt directly without reflection.
These Base classes extend Android's Activity and Service directly, and
are inside the internal Qt android package (under Qt6Android.jar).
For example, to handle onConfigurationChanged, instead of the current
way where we need this in QtActivityDelegate:
public void onConfigurationChanged(Configuration configuration)
{
try {
m_super_onConfigurationChanged.invoke(m_activity, configuration);
} catch (Exception e) {
e.printStackTrace();
}
handleUiModeChange(configuration.uiMode &
Configuration.UI_MODE_NIGHT_MASK);
}
And then this in QtActivity:
@Override
public void onConfigurationChanged(Configuration newConfig)
{
if (!QtLoader.invokeDelegate(newConfig).invoked)
super.onConfigurationChanged(newConfig);
}
public void super_onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
}
And having to keep it's Method handles around and then use Java
reflection
to call the override behavior done by Qt and the superclass methods.
instead of that, we can do it now in QtActivityBase like:
@Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
handleUiModeChange(newConfig.uiMode &
Configuration.UI_MODE_NIGHT_MASK);
}
Then, we would still have our user facing QtActivity class which extends
QtActivityBase and benefit from the same implementation of Qt logic done
in the base class.
An additional benefit to this approach is that now QtActivity will be
very lightweight and doesn't need to have all the boilerplate code as
before.

- elements are inserted in the container in a top-level test function,
then a CustomEvent is constructed and sendCustomGesture() is called,
which sends the events, invoking the GestureWidget::event() overload,
the latter iterates over the container, thus the container isn't
changed while it's being iterated over, because the code can't recurse
into the top-level test function and that's where the container is
modified later on (by inserting or by calling widget.reset() which

The implementation previously worked for non-short date-times, where
the offset has been remembered since construction. This included the
case of zoned times (and local times more than 2^55 msec away from the
start of 1970) that hit a spring-forward's gap; but excluded local
times that did the same (within 2^55 msec of the epoch).
This precluded an offset check in a spring-forward test, now added.
We can in fact determine the offset whenever we got a valid date and
time (we do so in the course of initializing the object, and when
asked for toMSecsSinceEpoch(), even when invalid), and we should not
use the value of the recorded offset if we didn't get a valid date and
time, so amend to always return 0 if we didn't get valid date and time
and always report the correct offset otherwise.
In the process, amend offsetFromUtc()'s computation to directly
resolve the date-time, rather than doing so via toMSecsSinceEpoch(),
which has to repeat decision-making offsetFromUtc() has already done
by the time it calls it. Also amend toMSecsSinceEpoch() to return 0 if
we didn't have a valid date and time to begin with, so it only
attempts to produce a useful result in the case where construction
attempted to resolve the date-time.

The resolution selects a point in time outside the gap, which will be
represented by toMSecsSinceEpoch()'s return, despite the QDT object's
isValid() returning false. Previously we retained the
originally-calculated msecs, so as to keep date() and time() matching
what was asked for. However, this required adjusting offset, which was
not remembered for local times within 2^55 milliseconds of the start
of 1970. This lead to an inconsistency between the offset from UTC
reported for the resolution for a local time further from the epoch,
or for a time-zone, and the actual offset from UTC at the time
indicated by the return from toMSecsSinceEpoch().
Instead, retain the actually calculated offset (even if we aren't
going to remember it) and adjust the msecs to the value that ensures
toMSecsSinceEpoch() will get the selected resolution. This
incidentally means that, when toMSecsSinceEpoch() has to re-resolve
(for a local time within 2^55 msecs of the epoch), it avoids
revisiting the complications of hitting the gap.
In passing, change internal stateAtMillis() to take the QTimeZone it
is passed by const reference, to save a copy (noticed during debug).
Also tweak a comment in a test to be explicit about a default value.

these values and offsetFromUtc() now match the point in time

If a QShortcut is registered with a QWindow as its parent, but QApplication
is used, we end up in QApplicationPrivate::createShortcutPrivate(), and
create a QtWidgetsShortcutPrivate that implements shortcut context matching
via qWidgetShortcutContextMatcher.
The problem is that qWidgetShortcutContextMatcher expects the windows
to be QWidgetWindows, which meant that plain QWindow based shortcuts
would always fail.
This can happen for example if a QApplication is used in Qt Quick
to provide dialog fallbacks, but QShortcuts are otherwise used
with plain QWindows, or QQuickWindows e.g.
We now defer the check of whether there's an active (widget) window,
and fall back to QtGui's simpleContextMatcher in case we don't find
a QWidget, QAction, or QGraphicsWidget shortcut owner to handle
the matching for.
Note: We don't support shortcut matching for QAction in QtGui,
but this is left for another day. There is also a discrepancy
between how QtGui and QtWidgets handles Qt::ApplicationShortcut.
The former will treat it as a match even if there is no active
QWindow, while the latter requires that there's an active widget

1. Support 3 ways to escape identifiers mentioned in SQLite Keywords
In SQLite Keywords (https://sqlite.org/lang_keywords.html), it shows
that there are 3 ways to escape identifiers, i.e., "", [], ``. So, I
have overridden "bool isIdentifierEscaped(const QString &,
IdentifierType)" to support it. In addition, there was a bug of
_q_escapeIdentifier. If there is a field name called length [cm],
which uses square brackets to show units, _q_escapeIdentifier will
not escape it to "length [cm]".
2. Identify identifiers correctly if identifiers have been escaped
There is a bug of QSQLiteDriver::record and
QSQLiteDriver::primaryIndex.
If we input escaped identifiers with separator, let's say
"databaseName"."tableName", both will change the input into
databaseName"."tableName, which is incorrect and causes
qGetTableInfo cannot get the right results. In addition, I overrode
stripDelimiters to strip "databaseName"."tableName" correctly.
There are still some assumptions for isIdentifierEscaped,
escapeIdentifier, and stripDelimiters, but I think this change it better
than what we have now.
1. For isIdentifierEscaped, if identifiers have a dot and the dot is a
separator, it is the users' responsibility to escape the pair of
schema and table name correctly. For example,
"aSchemaName"."aTableName", not "aSchemaName".a"TableName". That's
because we don't know whether the dot is just a dot of the name or a
separator.
2. For escapeIdentifier, if identifiers have a dot and the parts before
and after the dot are not escaped, escapeIdentifier will treat the
dot as part of the table name or field name. The same as the item
above, it is users' responsibility to do it right.
3. For stripDelimiters, the same as above, it is users' responsibility
to do escape if users want to use format schemaName.tableName or
tableName.fieldName.

Now that QtJniTypes::Objects are no longer primitive types that are the
same as a jobject, using those types in registered native functions
breaks. JNI will call those function with a jobject on the function
pointer, and lacking any type safety, the call to the registered
function will proceed with a wrong type of object on the stack.
To fix that, register the native function via a proxy that is a variadic
argument function, and unpack the variadic arguments into a list of
typed arguments, using the types we know the user-code function wants.
Then call the function with a tuple of those types using std::apply,

Instead of having a type that doesn't behave like a QJniObject, which
includes not holding a proper reference on the Java object, make the
QtJniTypes::Object type a QJniObject subclass that can be specialized
via CRTP to provide type-specific constructor and static functions.
QJniObject doesn't have a virtual destructor, but we subclass it only to
add a typed interface, without adding any additional data members.
Add versions of the static functions from QJniObjects to the
QtJniTypes::Object so that they can be called without explicitly
specifying the type or class name. This includes a constructor and named
constructors.
Constructing such objects means constructing a Java object of the class
the object type represents, as per the Q_DECLARE_JNI_CLASS declaration.
This is not without ambiguity, as constructing a type with a jobject
parameter can mean that a type wrapping an existing jobject should be
created, or that a Java object should be created with the provided
jobject as the parameter to the constructor (e.g. a copy constructor).
This ambiguity is for now inevitable; we need to be able to implicitly
convert jobject to such types. However, named constructors are provided
so that client code can avoid the ambiguity.
To prevent unnecessary default constructed QJniObjects that are then
replaced immediately with a properly constructed object, add a protected
QJniObject constructor that creates an uninitialized object (e.g. with
the d-pointer being nullptr), which we can then assign the constructed
jobject to using the available assignment operator. Add the special
copy and move constructor and assignment operators as explicit members
for clarity, even though the can all be defaulted.
Such QJniObject subclasses can then be transparently passed as arguments
into JNI call functions that expect a jobject representation, with the
QtJniTypes::Traits specialization from the type declaration providing the
correct signature.
QJniObject's API includes a lot of legacy overloads: with variadic
arguments, a explicit signature string, and jclass/jmethodID parameters
that are completely unused within Qt itself. In addition the explicit
"Object" member functions to explicitly call the version that returns a
jobject (and then a QJniObject). All this call-side complexity is taken
care of by the compile-time signature generation, implicit class type,
and template argument deduction. Overloads taking a jclass or jmethod
are not used anywhere in Qt, which is perhaps an indicator that they,
while nice to have, are too hard to use even for ourselves.
For the modern QtJniTypes class instantiations, remove all the overhead
and reduce the API to the small set of functions that are used all over
the place, and that don't require an explicit signature, or class/method
lookup.
This is a source incompatible change, as now QJniTypes::Object is no
longer a primitive type, and no longer binary equivalent to jobject.
However, this is acceptable as the API has so far been undocumented,
and is only used internally in Qt (and changes to adapt are largely
already merged).

If we construct the QJniObject from a jobject, then we know the jclass,
but not the class's name. If className is called while the stored name
is empty, get the name of the jclass and updated the stored value.

Fail the test when an unexpected warning message about a field, class,
or method not being found is generated from a JNI exception. Fix the
failure when trying to look-up a boolean field that is no longer
available, and ignore the one expected message from looking up an
unavailable class explicitly.

Support this both for parameters and return types, in all template
functions for calling methods or accessing fields.
To manage the life-time of the temporary objects, create a local stack
frame in the JVM around the calling function. Popping that implicilty
releases all local refernces, so that we don't have to worry about
doing so explicilty. Adding a local reference to the temporary jstring
objects is then enough for the object to live as long as it's needed.
The LocalFrame RAII-like type needs a QJniEnvironment to push and pop
the frame in the JVM, so we don't need a local QJniEnvironment anymore.
Reduce code duplication a bit as a drive-by, and add test coverage.
