ae03ffaffd tst_QStorageInfo::{tempFile,caching}: try a to find a non-btrfs storage
These tests skip when we're writing to a btrfs filesystem because, for
some reason, the amount of free space does not update synchronously with
file writing. But instead of giving up if $TMPDIR is a btrfs, let's try
and use the $XDG_RUNTIME_DIR, which is usually a tmpfs.

This will work in the CI for the openSUSE set ups, where / is btrfs,
/tmp is not a separate tmpfs, but /run/user/1000 is available.

FAIL!  : tst_QStorageInfo::tempFile() The computed value is expected to be different from the baseline, but is not

944200b5a9 JNI: Reduce amount of temporary QJniEnvironment instantiations
Almost all operations on a QJniObject require a QJniEnvironment,
including the construction and destruction of a QJniObject. Instead of
instantiating a temporary QJniEnvironment object in each call, store the
one from the constructor in the private, and reuse it.

Pass the stored environment through to other functions needing it, and
add a checkAndClearExceptions() wrapper.

Static class members still need their own QJniEnvironment, but we can
reuse the one we have to get both jclass and jmethodID rather than
creating new QJniEnvironments in several wrappers.

As a drive-by, clean up nullptr usage in the test that failed when
shortcutting isSameObject for the trivial cases.

b7a7351767 JNI: treat equivalent C++ types as the same JNI types as well
Our signature mapping treats both e.g. bool and jboolean as "Z", and it
is allowed to pass a bool variable as an argument to a function expecting
a jboolean. Except for fields and callMethod return values, where we only
allowed the JNI primitive types.

Fix this by comparing the signatures and size of the type we have with
the JNI types that there are explicit functions for. Cast from and to
the JNI type in both directions to address narrowing (e.g. jboolean is an
unsigned char and converting to bool would be narrowing, even though
both are 8bit types).

This way we can get boolean fields using getField<bool>, and int fields
using getField<int> etc.

77c661b275 moveToTrash/Unix: use lower-level API to write the info file
So we can more easily get any errors from attempting to write the file.
It is possible to get them with QFile, by either doing .flush() or using
QIODevice::Unbuffered, but using the C API is a definite sure way. Plus,
since this is QFileSystemEngine, this avoids the possibility that QFile
may choose to use a different file engine than the native one, for some
reason. And it reduces overhead.

This allows us to more easily detect why the file creation failed and
therefore stop looping if the error wasn't EEXIST. That will avoid an
infinite loop in case the necessary directories exist but aren't
writable.

It's also moved above the renaming, such that the failure to populate
the info file prevents the renaming too. Both operations can have the
same likely errors, ENOSPC and EIO. The likelihood of EIO is very low,
for both; but for ENOSPC it's far more likely for writing the
file. Avoiding the ENOSPC error for the renaming is handled in a later
commit.

80d4d55e25 JNI: add QJniArray class for easier working with arrays
Implements an iterator API and other standard member access functions
for sequential containers so that we can use ranged-for over an object
that is a jarray. Provides read-only access to individual elements
(which is mostly relevant for arrays of objects), or the entire data()
as a contiguous memory block (which is useful for arrays of primitive
types).

QJniObject call functions can return QJniArray<T> when the return type
is either explicitly QJniArray<T> or T[], or their Qt equivalent (e.g.
a jbyteArray can be taken or returned as a QByteArray). If the return
type is a jarray type, then a QJniObject is returned as before.

Arrays can be created from a Qt container through a constructor or the
generic fromData named constructor in the QJniArrayBase class, which
implements the generic logic.

Not documented as public API yet.

Added a compile-time test to verify that types are mapped correctly.
The function test coverage is added to the QJniObject auto-test, as
that already provides the Java test class with functions taking and
returning arrays of different types.

3b6d288e3b Android: Simplify Qt for Android hierarchy, less Java reflection!
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.

(QActivity, QtService and QtApplication) by implementing base
classes which use the delegate implementions directly and avoid

c23d00078c Let QDateTime::offsetFromUtc() work for invalid date-times
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.

4aba97e062 Adjust msecs instead of offset for spring-forward resolution times
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.

[ChangeLog][QtCore][Possibly Significant Behavior Change] When
QDateTime is instantiated for a combination of date and time that was
skipped, by local time or a time-zone, for example during a
spring-forward DST transition, the invalid result's time() - and, in
rare cases, date() - no longer match what was asked for. Instead,
these values and offsetFromUtc() now match the point in time
identified by toMSecsSinceEpoch().

1219dbcd12 QPointer: ensure construction from nullptr is constinit'able
Construction from nullptr wasn't, before, because it was using the
QPointer(T*) constructor, which cannot be constexpr. Add a constexpr
QPointer(std::nullptr_t) constructor to enable this use-case.

This requires to mark the (T*) constructor as Q_WEAK_OVERLOAD,
otherwise legacy construction from a literal 0 would be ambiguous.

No documentation changes needed, as the set of valid expressions
(apart from constinit'ing) has not changed. Mention the nullptr ctor,
though, without \since.

Add a test to confirm that contruction from derived still works.

185c3b080c JNI: Fix native functions that take a declared QtJniTypes class
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,
which gives us type safety and implicit conversion for free.

Add a test that exercises this.

62cb5589b3 JNI: Make declared QtJniTypes classes proper QJniObjects
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).

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.

89b6ad3ab5 QWeakPointer: fix the converting constructor from rvalues
When constructing a QWeakPointer<T> from a rvalue QWeakPointer<X>,
even if X* is convertible to T*, actually doing the conversion
requires access to the pointee's vtable in case of virtual inheritance.

For instance:

  class Base { virtual ~Base(); };
  class Derived : public virtual Base {};

Now given a `Derived *ptr`, then a conversion of `ptr` to `Base *` is
implicit (it's a public base), but the compiler needs to dereference
`ptr` to find out where the Base sub-object is.

This access to the pointee requires protection, because by the time we
attempt the cast the pointee may have already been destroyed, or it's
being destroyed by another thread. Do that by going through a shared
pointer. (This matches the existing code for the converting assignment.)

This requires changing the private assign() method, used by QPointer, to
avoid going through a converting move assignment/construction, because
one can't upgrade a QWeakPointer tracking a QObject to a QSharedPointer.
Given it's the caller's responsibility to guard the lifetime of the
pointee passed into assign(), I can simply build a QWeakPointer<T> and
use ordinary (i.e. non-converting) move assignment instead.

If a move-to-trash operation failed, e.g. because the file was opened by

MSDN documents the IFileOperation::PerformOperations to return whether

operations' success.

If the operation succeeded is reported by an HRESULT parameter
of the IFileOperationProgressSink::PostDeleteItem implementation,
and we ignored that parameter so far.

Check it via the SUCCEEDED macro, and set a boolean sink variable based
on that, which we can inspect to return the correct value.

Augment the test case by opening those files we create ourselves, and
if that fails (which it will on Windows, but not necessarily on other
platforms), then try again after closing the file. If the first attempt
succeeded, then the source file must also be gone.

6c504f2519 QPointer: also provide a converting assignment operator
d026fad3d9 added converting constructors
for QPointer. This however made converting _assignments_ ambiguous,
introducing a regression for users coming from Qt < 6.6.

This code:

  QPointer<Base> base;
  QPointer<Derived> derived;
  base = derived;

used to convert `derived` to `Derived *` (using the implicit conversion
operator from `QPointer<Derived>` to `Derived *`), and then the
assignment operator for `QPointer<Base>` that took a `Base *`.

The introduction of the conversion constructor in 6.6 makes it possible
to convert `QPointer<Derived>` to `QPointer<Base>`, and then fall back
to the compiler-generated assignment operator for `QPointer<Base>`.

The result is that the code above is now ambiguous and stops compiling.

Fix this by adding a converting assignment operator for QPointer.
I'm only adding the const-lvalue overload because the implementation
requires going through the private QWeakPointer::assign helper. We
cannot copy-assign or move-assign the inner QWeakPointer, as those
assignments require lock()ing the QWeakPointer and that's not possible
on a QObject-tracking QWeakPointer (but cf. QTBUG-117483).

Assigning from a rvalue QPointer would mean calling assign() on
the internal QWeakPointer _and_ clear the incoming QPointer,
and that's strictly worse than the lvalue overload (where we just call
assign()).

Perhaps this type becomes obsolete at some point with std::string being

renaming it us safe.

Until submodules are ported, leave a compatibility alias String type,
which also prevents us from declaring a String JNI class in tests until
the alias is removed in a later commit.
