Marc Mutz effbf147a4 QUnicodeTables: use array for case folding tables
Instead of four pairs of :1 :15 bit fields, use an array of four :1,
:15 structs.  This allows to replace the case folding traits classes
with a simple enum that indexes into said array.

I don't know what the WASM #ifdef'ed code is supposed to effect (a :0
bit-field is only useful to separate adjacent bit-field into separate
memory locations for multi-threading), but I thought it safer to leave
it in, and that means the array must be a 64-bit block of its own, so
I had to move two fields around.

Saves ~4.5KiB in text size on optimized GCC 10 LTO Linux AMD64 builds.

Fix by reshuffling the elements and adding a static_assert for the

When reallocating we assume we will grow more and increase the size to
the next power of 2. However, this might be a size where we end up with
space we cannot take advantage of. Such as having 4 bytes free at the
tail when we have 8 byte objects. The larger the objects are the greater
the chance is that we will end up in this situation, and it would have
a greater chance to leave big allocated chunks unused.

Volker Hilsheimer ca3be92234 Remove QFileInfo::type and related enum from 5.14
The API is problematic for several reasons:
- the mixing of flags and enum in a single enum type
- the name "type" as somewhat overloaded
- the ease of misuse when comparing the result rather than testing
  for a bit being set

In light of this, focus for 5.14 on the new isShortcut and
isSymbolicLink functions, thus migitating the problematic
isSymLink which conflates the two concepts.

the container remains valid even with 52 "months" (though the code
that calculates its runtime size will naturally need to be adjusted).

Alex Trotsenko 81408c0e76 QEventDispatcherWin32: avoid livelock in a foreign event loop
According to Windows docs, GetMessage() function retrieves the messages
from the input queue in defined order, where posted messages are
processed ahead of input messages, even if they were posted later.
Therefore, if the application produces a posted event permanently, as
a result of processing that event, user input messages may be blocked
due to hard CPU usage by the application.

It's not a problem, if an internal Qt event loop is running. By calling
sendPostedEvents() on the beginning of processEvents(), we are sending
posted events only once per iteration. However, during execution of
the foreign loop, we should artificially lower the priority of the
WM_QT_SENDPOSTEDEVENTS message in order to enable delivery of other
input messages.

To solve the problem, it is proposed to postpone the
WM_QT_SENDPOSTEDEVENTS message until the message queue becomes empty,
as it works for the internal loop.

In QFutureInterface, change the return type of mutex() from

to std::lock_guard. We need to keep the old method around
for BC reasons, so the new one needs an artificial function

Ryan Chu 7a4e5e7433 Make Qt aware of symlinks and shortcuts on Windows
Qt has traditionally considered Windows shortcut files equivalent to
symlinks on Unix file systems. Because of NTFS symlinks, the
interpretation of shotcut files as symlinks is confusing.

In this change, QFileInfo treats shortcut (.lnk) files as regular files
but can follow the pointed object.

In addition, QFileInfo introduces a more comprehensive file type. So
that applications can make well-informed decisions about how to treat a
file system entry.

Based on the implementation of QFileInfo::type(), two inline helper
functions are introduced to QFileInfo.
1. isSymbolicLink, returns true if it points to a symbolic link.
2. isShortcut, returns true if it points to a shortcut.

[ChangeLog][QtCore][QFileInfo] Introduce QFileInfo::type() to replace
the isSymLink method.

Marc Mutz 09b0038513 Short live qt_unique_lock/qt_scoped_lock! (until C++17)
Now that QRecursiveMutex is getting split off of QMutex, QMutexLocker
will stop working on QRecursiveMutex once the split has been finalized
in Qt 6.

Even today, QMutexLocker contains casts from QBasicMutex to QMutex
that some reviewers are uncomfortable with. One way to carry
QMutexLocker forward is to template it on the mutex type, possibly
with aliases like QBasicMutexLocker and QRecursiveMutexLocker. C++17
code would then not require a port, thanks to CTAD.

But we have the problem now, and we can't template QMutexLocker in Qt 5.

The alternative is to look at std and realize that they have surpassed
QMutexLocker in expressiveness already. A scoped_lock cannot be
unlocked again, a unique_lock can be moved around. QMutexLocker
doesn't do either. The only "problem" is that the std lock classes are
already templates, but we can't, yet, rely on C++17 CTAD to make them
look as if they weren't.

So, prepare for a future with C++17 CTAD by writing factory functions,
qt_scoped_lock and qt_unique_lock, which will later port mechanically
to their C++17 equivalents (mostly).

The functions are added to a new private qlocking_p.h becauee we don't
want to make them public. These are for use in Qt's own implementation,
or for users that don't care about compatibility and will not mind them
to be removed once we depend on C++17. Originally, I planned to use
qmutex_p.h instead, but that header is not self-contained and causes
build errors when we started to include it into libraries other than
QtCore.

Regarding the return value of qt_scoped_lock: Ideally, we'd like to
return a std::scoped_lock, but two things stand in the way: First,
scoped_lock was only added in C++17 (we fall back to lock_guard if
scoped_lock is not available). Second, returning one from a function
requires C++17 guaranteed copy elision, because neither scoped_lock
not lock_guard have a copy ctor. In order for code not to come to
depend on a particular lock class, we return any of lock_guard,
unique_lock or scoped_guard, depending on what the compiler supports,
and therefore wrap the functions in the unnamed namespace to avoid
running into ODR if (private) headers are used from different projects
(autotests, e.g.). By the time we can drop them, however, qt_*_lock
will be semantically 100% identical to their replacements.

Port some initial users.

This commit adds transitive dependencies to the plugins, so that a
sane set of default plugins get auto-imported when linking against a
module. It also provides a new function, qt5_import_plugins(), which
allows you to override the set of plugins that get imported. The decision
of whether or not to import a specific plugin is based on several custom
target properties and a very clever generator expression.

Note that this change only imports plugins on static Qt builds. It
does nothing on shared Qt builds, as the shared libraries already have
their own plugin import mechanism.

Volker Hilsheimer b7d073e990 Refactor memory allocation for arguments of QMetaCallEvents
There are two cases:

In a BlockingQueuedConnection, QMetaCallEvent doesn't allocate memory
and instead passes already existing pointers through. A QSemaphore
is used to serialize data access between threads. So the constructor
taking a QSemaphore can be simplified to only accept an existing arg
array.

In a QueuedConnection, QMetaCallEvent needs to make deep copies of
the arguments, and memory needs to be allocated based on the number
of arguments. The previous code put the burden of memory allocation
on the code generating the event, while the memory was free'd by
~QMetaCallEvent. Instead, make it QMetaCallEvent's responsibility
to allocate and free the memory as needed, and adjust the code
generating QMetaCallEvents.

We can allocate the memory for types and pointers to arguments in a
single block, starting with the space for the array of void*, followed
by the space for the array of integers to avoid byte alignment issues.
By pre-allocating the space that's needed by three arguments, we can
avoid all mallocs for the majority of QMetaCallEvents.

Until this change has propagated through qt5.git, we need to keep the
old API that is still used by QtDeclarative around. Once QtDeclarative
has migrated to the new API, it can be removed.

Marc Mutz 5f1f0fe0b7 QDateTimePrivate: inherit QSharedData and other cleanups
Don't manage the ref-count yourself, as this requires the code to use
the QAtomic copy ctor, which we want to remove going forward. Using
QSharedData, we can let the compiler write the code for us.

Since 'ref' this way moves to the first spot in the list of effective
members, creating a 4B hole between itself and 'msecs', swap 'status'
and 'msecs' to fill the hole:

  offset:   0       8      16      24
            |       |       |       |
  without   v       v       v       v
  adj.mnt: |*R*|   | msecs | S | U | TZ....
  before:  | msecs | S | U |*R*|   | TZ...
  after:   |*R*| S | msecs | U |   | TZ....

This keeps the padding out of the critical first word, which improves
latency. That said, for accessing the members the old layout surely was
optimal. This layout optimizes copies and pessimizes access to 'msecs'
on 32-bit platforms without the Critical Word First optimization.

Requires adjustments to tst_toolsupport and the qhooks version.

Also default members using NSDMI, consequently drop the manual default
ctor.

Marc Mutz 787e498487 QMutexPool: fix memory order of atomic operations
The array of QAtomicPointer<QMutex> can be initialized using relaxed
stores of nullptr, since nullptr is the whole data. But once we store
an actual QMutex pointer in the array, we need to publish the indirect
data thus created. We did this, with testAndSetRelease(); what was
missing was a corresponding acquire fence on load, without which there
is no happens-before relationship between the writes performed by the
QMutex ctor and the reads performed by a subsequent mutex.lock(), say,
on the same data.

Fix by adding acquire fences to all loads. That includes the dtor,
since mutexes may have been created in different threads, and never
been imported into this_thread before the dtor is running.

As a drive-by, return a new'ed QMutex that was successfully installed
directly to the caller, without again going through a load-acquire.

Marc Mutz 6bc7309135 QResource: fix nullptr-check gone tautological
Amends 136c5b9338.

Before that change, each of the three members was a separate
Q_GLOBAL_STATIC, so checking resourceList() for nullptr was the
correct thing to do to find out whether the static was already
destroyed.

After the change, the resourceList() function will never return
nullptr. Either resourceGlobalData.isDestroyed(), in which case
dereferencing it asserts, or it isn't, in which case resourceList()
returns a valid pointer.

An explicit isDestroyed() check was added to the unregister function,
but the register one was also checking resourceList() for nullptr,
and this was left unprotected.

Add the check and remove the now-tautological checks for nullptr
resourceList().

Marc Mutz fd42589b14 Extend QString::arg(QString, ..., QString) to more than 9 arguments
Now that we have QStringView::arg(), we can use it to implement a
similarly flexible QString::arg(). It's not as straight-forward as in
QStringView, though: QString has existing arg() overloads that all
become worse matches with the introduction of the new,
perfectly-forwarding overload.

So in order to allow calling of the other arg() functions, first
constrain the new arg() function to arguments that are convertible to
QString, QStringView, or QLatin1String, and then delegate to the
QStringView version. To stay compatible with the previous overloads,
which accepted anything that implicitly converts to QString (in
particular, QStringBuilder expressions), add a new overload of
qStringLikeToView, taking const QString &. This benefits the existing
QStringView and QLatin1View versions, too.

[ChangeLog][QtCore][QString] QString::arg(QString, ..., QString) can
now be called with more than nine arguments, as well as with
QStringViews.

Thiago Macieira 9b8493314d Qt6: Fix uninitialized meta objects on Windows
Windows has a problem relating to cross-DLL variable relocations: they
are not supported. Since QMetaObject's link to the parent class is done
via a pointer, every QMetaObject in a DLL or in the EXE that derives
from a class from another DLL (such as QObject) will be dynamically
initialized.

This commit changes the meta object pointers in QMetaObject::d from raw
pointers to a wrapper class SuperData, which is almost entirely source-
compatible with the pointer itself. On all systems except for Windows
with Qt 6, it's binary compatible with the current implementation.

But for Windows with Qt 6, this commit will store both the raw pointer
and a pointer to a function that returns the QMetaObject, with one of
them non-null only. For all meta objects constructed by moc, we store
the function pointer, which allows the staticMetaObject to be statically
intialized. For dynamic meta objects (QMetaObjectBuilder, QtDBus, QtQml,
ActiveQt), we'll store the actual raw pointer.

[ChangeLog][QtCore][QMetaObject] Some internal members of the
QMetaObject class have changed types. Those members are not public API
and thus should not cause source incompatibilities.

The macro QT_NO_DATA_RELOCATION existed in Qt 4 but was called
Q_NO_DATA_RELOCATION and only applied to Symbian. It was removed in
commit 24a72c4efa ("qglobal: Remove
symbian specific features").
