It has been the case for both QStringLiteral and QByteArrayLiteral
since Qt 5.0, and Q_ARRAY_LITERAL since Qt 6.0.
Since it's definitely surprising, add a note in the docs, which
is "somehow" consistent with the interpretation of capacity as
the biggest possible size before we reallocate. Since it's 0,
any manipulation of the size will cause a reallocation.
(Alternatively: the capacity() is for how many elements memory was
requested from the free store. No memory was allocated, so 0...)

The old overload with int is visible when querying the metaobject system
so string-based connects still work as before, and connecting to it will

At the same time the PMF-based connect will, on recompile, pick the
QSocketDescriptor overload. As an added improvement it also comes with
the notification type, removing the need for separate slots where the
code would be mostly shared anyway.
The QSocketDescriptor type can be implicitly converted to and from

Use P0608's trick to detect convertibility without narrowing;
and now that we can depend on C++17, use its features.
First, this moves the burden of detecting a narrowing conversion on
the compiler, rather than us maintaining a complicated series
of checks. Of course, this exposes
* bugs in compilers (e.g. GCC < 9 thinks that float->bool is not
narrowing;
* behavior still not (widely) implemented (pointer to bool
conversions are narrowing, P1957);
* interesting compiler choices, e.g. GCC 9 thinks that unscoped
enumerations are non-narrowing convertible to a datatype big
enum to contain all the _enumerators_, even if the underlying
type of the enum (and/or its sizeof()) is wider than the target
datatype.
Second, it allows to detect conversions that have a narrowing
conversion as an intermediate step. Given a type like
struct Bad { operator double() const; };
then an object of type Bad is implictly convertible to a type
like int via a narrowing conversion. Therefore, a connection
is possible between a signal carrying a Bad and a slot accepting
an int. We can now detect and block this.
Tests regarding scoped enumerations have been dropped,
for the simple reason that a scoped enumeration is not
implictly convertible to an integral type, so we don't have
that detection (it would constantly fail). Scoped enumerations
do not take part in narrowing conversions anyhow, cf. [dcl.init.list].
[ChangeLog][QtCore][QObject] The detection of narrowing conversions

QT_NO_NARROWING_CONVERSIONS_IN_CONNECT now takes also

The double-swap technique I used was flawed and broke on
self-assignment. What I had meant to use was the move-and-swap
technique. Thanks to Peppe for pointing it out.
This also fixes a compiler bug in the Green Hills compiler. It was
finding the wrong "swap" function in qSwap:
using std::swap;
swap(value1, value2);
It's supposed to find swap(QCborValue &, QCborValue &) due to argument-
dependent lookup. It's instead finding std::swap<QCborValue>, which
recurses.

The old implementation was either using CRC32 on modern processors
or a trivial, but rather slow implementation.
We can't continue with CRC32, as that implementation can only
give us 32bit hashes, where we now need to support 64bit in Qt 6.
Change the implementation to use MurmurHash, as public domain
implementation that is both very fast and leads to well distributed hashes.
This hash function is about as fast as the SSE optimized CRC32 implementation
but works everywhere and gives us 64 bit hash values.
Here are some numbers (time for 10M hashes):
14 char 16 char
QByteArray QString float
old qHash (non CRC32) 127ms 134ms 48ms
old qHash (using SSE CRC32 instructions 60ms 62ms 46ms
new qHash 52ms 43ms 46ms
Unfortunately MurmurHash is not safe against hash table DoS attacks, as
potential hash collisions are indepenent of the seed. This will get
addressed in followup commit, where we use SipHash or an SSE optimized
AES based hashing algorithm that does not have those issues.

A brand new QHash implementation using a faster and more memory efficient data
structure than the old QHash.
A new implementation for QHash. Instead of a node based approach as the old
QHash, this implementation now uses a two stage lookup table. The total
amount of buckets in the table are divided into spans of 128 entries.
Inside each span, we use an array of chars to index into a storage area
for the span.
The storage area for each span is a simple array, that gets (re-)allocated
with size increments of 16 items. This gives an average memory overhead of
8*sizeof(struct{ Key; Value; }) + 128*sizeof(char) + 16 for each span.
To give good performance and avoid too many collisions, the array keeps its
load factor between .25 and .5 (and grows and rehashes if the load factor goes
above .5).
This design allows us to keep the memory overhead of the Hash very small, while
at the same time giving very good performance. The calculated overhead for a
QHash<int, int> comes to 1.7-3.3 bytes per entry and to 2.2-4.3 bytes for
a QHash<ptr, ptr>.
The new implementation also completely splits the QHash and QMultiHash classes.
One behavioral change to note is that the new QHash implementation will not
provide stable references to nodes in the hash when the table needs to grow.
Benchmarking using https://github.com/Tessil/hash-table-shootout shows
very nice performance compared to many different hash table implementation.
Numbers shown below are for a hash<int64, int64> with 1 million entries. These
numbers scale nicely (mostly in a linear fashion with some variation due to
varying load factors) to smaller and larger tables. All numbers are in seconds,
measured with gcc on Linux:

When a class has multiple QProperty members to implement functionality,
it is common to have functions in the class that react to changes. For
example to emit a compatibility signal, in case of Qt Quick to mark the
scene graph as dirty, etc. etc.
To faciliate this use-case, this patch adds an internal
QPropertyMemberChangeHandler template that allows connecting a QProperty
field to a member function callback.
At the moment that callback is still 3 * sizeof(pointer). This could in
theory be reduced to 2 by eliminating the back-pointer (prev) as the
observer lives as long as the property. That however belongs into maybe
a future patch.
In order to get a pointer back to the surrounding object that holds the
QProperty as well as provides the callback function, the property system
was changed to pass through the address of the QProperty member at
run-time, and at compile time the delta from the QProperty member to the
beginning of the surrounding class is calculated. Through subtraction we
obtain the pointer to the owning object.

QFuture's original design pre-dates C++11 and its
introduction of move semantics. QFuture is documented
as requiring copy-constructible classes and uses copy
operations for results (which in Qt's universe in general
is relatively cheap, due to the use of COW/data sharing).
QFuture::result(), QFuture::results(), QFuture::resultAt()
return copies. Now that the year is 2020, it makes some
sense to add support for move semantics and, in particular,
move-only types, like std::unique_ptr (that cannot be
obtained from QFuture using result etc.). Taking a result
or results from a QFuture renders it invalid. This patch
adds QFuture<T>::takeResults(), takeResult() and isValid().
'Taking' functions are 'enabled_if' for non-void types only
to improve the compiler's diagnostic (which would otherwise
spit some semi-articulate diagnostic).
As a bonus a bug was found in the pre-existing code (after
initially copy and pasted into the new function) - the one
where we incorrectly report ready results in (rather obscure)
filter mode.

QtQml needs the private just for one detail which nobody else should
need it for: Tracking additional dependencies and marking the binding as
dirty. Exporting the private requires hiding some variables and
providing accessors, to compile with MSVC - including the removal of
QVarLengthArray usage. Upside: The binding structure shrinks by 8 bytes
and the encapsulation makes it a little easier to change things without
breaking declarative, ... in the unlikely event ;-)
Also remove setDirty() from the public API as it's not needed by QtQml
and using it is dangerous, because it means that there's a risk of
somebody keeping a reference (count) to the untyped binding from within
the binding closure, which introduces a memory leak.

Added QFuture::then() methods to allow chaining multiple asynchronous
computations.
Continuations can use the following execution policies:
* QtFuture::Launch::Sync - the continuation will be launched in the same
thread in which the parent has been executing.
* QtFuture::Launch::Async - the continuation will be launched in a new
thread.
* QtFuture::Launch::Inherit - the continuation will inherit the launch
policy of the parent, or its thread pool (if it was using a custom one).
* Additionally then() also accepts a custom QThreadPool* instance.
Note, that if the parent future gets canceled, its continuation(s) will
be also canceled.
If the parent throws an exception, it will be propagated to the
continuation's future, unless it is caught inside the continuation
(if it has a QFuture arg).
Some example usages:
QFuture<int> future = ...;
future.then([](int res1){ ... }).then([](int res2){ ... })...
QFuture<int> future = ...;
future.then([](QFuture<int> fut1){ /* do something with fut1 */ })...
In the examples above all continuations will run in the same thread as
future.
QFuture<int> future = ...;
future.then(QtFuture::Launch::Async, [](int res1){ ... })
.then([](int res2){ ... })..
In this example the continuations will run in a new thread (but on the
same one).
QThreadPool pool;
QFuture<int> future = ...;
future.then(&pool, [](int res1){ ... })
.then([](int res2){ ... })..
In this example the continuations will run in the given thread pool.

This pulls the CMake port, which not only adds CMake files but also
modifies existing code. A brief summary of "seemingly unrelated" changes:
* configure.json was re-formatted to not use multi-line strings. That
is an extension of the Qt JSON parser but not JSON compliant, which
is needed for the configure.json-to-cmake conversion script (python).
* Some moc inclusions were added due to CMake's slightly different way
of handling moc. With the changes the files build with qmake and cmake.
* Since CMake just grep's for the Q_OBJECT macro to determine whether to
call moc (instead of doing pre-processing like qmake), the existing use
of "Q_OBJECT" in our documentation was changed to \Q_OBJECT, which cmake
doesn't see and which is now a qdoc macro.
* QTestLib's qFindTestData was extended to also search in the source
directory known at build time.
What this change also brings is a new way of building modules in Coin by using
YAML configuration files that describe the steps of building and testing in Coin
specific terms. The platform configuration files in qt5 are instructed to use the
old Coin built-in way of testing ("UseLegacyInstructions" feature) but for any
configurations that do not have this, these yaml files in the coin/ sub-directory
are used and shared across repositories.

On macOS it's possible to configure the system locale to not do digit
grouping (separating "thousands", in most western locales); it then
returns an empty string when asked for the grouping character, which
QLocale's system-configuration then ignored, falling back on using the
base UI locale's grouping separator. This could lead to the same
separator being used for decimal and grouping, which should never
happen, least of all when configured to not group at all.
In order to notice when this happens, query() must take care to return
an empty QString (as a QVariant, which is then non-null) when it *has*
a value for the locale property, and that value is empty, as opposed
to a null QVariant when it doesn't find a configured value. The caller
can then distinguish the two cases.
Furthermore, the group and decimal separators need to be distinct, so
we need to take care to avoid cases where the system overrides one
with what the CLDR has given for the other and doesn't over-ride that
other.
Only presently implemented for macOS and MS-Win, since the (other)
Unix implementation of the system locale returns single QChar values
for the numeric tokens - see QTBUG-69324, QTBUG-81053.

We have long (since 4.5.1) coerced it to lower-case, for no readily
apparent, much less documented, reason. CLDR says most locales use an
upper-case E for this - let's actually use what CLDR says we should
use.
The code that matches the exponent separator was doing so
case-insensitively in any case; that needed adaptation now that the
separator's case isn't pre-determined; and, in any case, should have
been done using case-folding rather than upper-casing. In the process,
removed some spurious checks for "'e' or 'E'" in the result, since the
exponent separator is always represented by 'e' (and an 'e' might also
be present for the separate reason of its use as a beyond-decimal
digit representing fourteen).

This implements the operation for Windows, macOS, and Unix, for now

added in a separate commit.
The Unix implementation follows the freedesktop.org specification [1]
version 1.0.
[1] https://specifications.freedesktop.org/trash-spec/trashspec-1.0.html
On macOS and Windows, native APIs are used, with each having some
limitations:
* on macOS, the file in the trash won't have a "put back" option,
as we don't use Finder automation, for the reasons provided in the
comments
* on Windows, we might not be able to use the modern IFileOperation
API, e.g. if Qt is built with mingw which doesn't seem to provide
the interface definition; the fallback doesn't provide access to
the file name in the trash
The test case creates files and directories, and moves them to the
trash. As part of the cleanup routine, it deletes all file system
entries created. If run on Windows without IFileOperations support,
this will add a file in the trash for each test run, filling up
hard drive space.

Use QStringIterator rather than indexed loops. This fixes handling of

definitions: a string is lowercase/uppercase if it's equal to its

As a side effect, empty strings are now correctly reported to be

[ChangeLog][Important Behavior Changes] The semantics of
QString::isLower() and QString::isUpper() have been changed to match the
Unicode specification. Now lowercase (resp. uppercase) strings are
allowed to contain any character; a string is considered lowercase
(resp. uppercase) if it's equal to its own toLower() (resp. toUpper())
folding. Previously, a non-letter character would make the string not
lowercase nor uppercase, and the mere presence of an uppercase (resp.
lowercase) letter would make isLower() (resp. isUpper()) return false,
even if the letter wouldn't change under case folding. As a
consequence, now empty strings are lowercase and uppercase.

QString::isLower() and QString::isUpper(). Empty strings are now

In the presence of multiple overloads of a function taking either

The rationale is that the QStringView overload may have been
added "later" (read: the function was written when QStringView
was not available yet, so it took QString), and the fact that
a function with the _same name_ offers a QStringView overload
implies the function never needed to store/own the string in
the first place.

preparation for a future QString(char16_t*) constructor

This commit discovered that MSVC cannot handle constexpr arrays bigger

too large for constant-expression evaluation").
Note also that this requires gzip or zstd to be in PATH for compression
to happen. RCC linked to zlib, which is always present due to the
bundled copy. gzip's presence is not likely to be a problem on Unix

is not present, QtCore's size will increase by about 1910 kB of

I'd have preferred to use QArrayDataPointer<ushort> for QString, but
that option wasn't the best one. QArrayDataPointer try to do some
operations using QArrayDataOps and that would expand to unnecessary
code. What's more, the existing code expected to be able to modify and
access the d pointer.
Instead, this commit introduces QStringPrivate (named differently from
QStringData to catch potential users), which contains the three
members. This POD class is also used in QJsonValue to store the
"inlined" QString. QHashedString in qtdeclarative will need a similar

This is part of the migration of qtbase from QRexExp to
QRegularExpression.
[ChangeLog][QtCore][QAbstractItemModel] The match() method now
supports the new Qt::RegularExpression match flag value. This
will allow users to use either a string or a fully configured
QRegularExpression when doing searches. In the second case,
the case sensitivity flag will be ignored if passed.

Note that android builds will be broken after this merge and
regeneration, because we don't currently handle the minimum required
changes that were brought in with the Android multi ABI support
that comes from 5.14.
This will have to be addressed in a separate change.
For now the build on Android will fail while compiling due to incorrect
generation of LIB_SUFFIX with QT_ARCH.

Always try to create the runtime directory and never change
the permissions of an existing directory. Conform to the
XDG Base Directory Specification:
"If, when attempting to write a file, the destination directory
is non-existent an attempt should be made to create it with
permission 0700. If the destination directory exists already
the permissions should not be changed."

Only allow implicit conversions when the types involved are compatible.
That means, only allow construction and copy assignment when the type
X* is convertible to type T*. This is done using SFINAE and the
std::is_convertible type trait, which makes the previous
QSHAREDPOINTER_VERIFY_AUTO_CAST obsolete.
This patch fixes compilation when a function is overloaded with
Q{Shared,Weak}Pointer of different, incompatible types. Previously, this
resulted in a compilation error due to an ambiguous overload.
