2a11940b2a tst_stringview: remove dead code
wchar_t hasn't been QStringView's storage_type for a very long time
(at least since 5.10). And in Qt 6, we require char16_t support not
only in the compiler, but also in the stdlib, so drop the guards and
the alternative code paths.

dd4e96df52 tst_qstringview: modernize functions in help namespace
They don't work with std::span, since std::span has neither
const_iterator nor cbegin()/cend().

To fix, perfectly forward the return type with decltype(auto) instead
of mentioning T::const_iterator, and rely on the const-qualfication of
the help::c{r,}{begin,end}() functions' arguments to select the
correct T::{r,}{begin,end}() overload.

e325bd68fd Catch overflow in QDateTime::fromSecsSinceEpoch()
It's documented to be undefined if the number of seconds is outside
the allowed range, but it doesn't hurt for that undefined behavior to
happen to be that the result is invalid. Added a simple test.

5ba66c5622 Remove all locale-dependence from Q(Date|Time)+
[ChangeLog][Important Behavior Changes][QDateTime] Removed all
locale-dependence from QDate, QTime and QDateTime, including the
Qt::DateFormat members that select the formats of the default and
system locales and the toString(Qt::DateFormat, QCalendar) overload,
which only used its calendar for these formats.  All toString()
methods now use, and all fromString() methods only recognize, the C
locale's names for days and months.  Use QLocale's methods if you need
to take locale into account.

It clearly belonged in tst_QDate::toDateTime(), for which it adds a

The new testing of case-insensitivity doesn't work if the format

a033c23ddf QFile::moveToTrash: work with relative file paths on Windows
The system APIs expect an absolute "display name" of the file path,
so make it absolute.

The test was overly tolerant in accepting failure, as a QStorageInfo
initialized with a file path that doesn't exist is invalid, and thus
always different from the QStorageInfo of the home directory. Fix the
test to compare only valid QStorageInfo objects, and postpone the check
until the file we want to move has been created.

not overflow and we'll need the multiplication anyway.

300aaec2f9 Fix digit grouping when digits are surrogat pairs
This is a follow-up to commit ed2b110b6a
to fix indexing errors. Added the test that should have accompanied
that commit, which found some bugs, and refined the Indian number
formatting test (on which it's based).

Make variable i in the loops that insert grouping characters in a
number be consistently a *character* offset - which, when each digit
is a surrogate pair, isn't the same as an index into the
QString. Apply the needed scaling when indexing with it, not when
setting it or decrementing it. Don't assume the separator has the same
width as a digit.

Differences in index no longer give the number of digits between two
points in a string, so actively track how many digits we've seen in a
group when converting a numeric string to the C locale. Partially
cleaned up the code for that in the process (more shall follow when I
sort out digit grouping properly, without special-casing India).

487dd80bce Introduce QSocketNotifier::activate(QSocketDescriptor, QSN::Type)
The pre-existing overload passes an int, but this can mean the
descriptor gets truncated in compilations where the descriptor
is 64-bit.

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
produce a deprecation warning in the output.
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
qintptr to ensure existing code still compiles. It can also be
constructed from Qt::HANDLE on Windows.

In this same patch I also update the existing string-based connects in
this module, which then includes updating the parameters for some slots
as well.

[ChangeLog][QtCore][QSocketNotifier] Added
QSocketNotifier::activated(QSocketDescriptor, QSocketNotifier::Type).
This replaces the activated(int) signal which in 64-bit environments
could truncate the socket descriptor. If you use "activated" with the
string-based connect() then you need to update the parameter type of the
signal and slot if it had one. If you use it with the pointer to member
function based connect() then all you need to do is update your slot's
parameter type if it has one. If you need to compile your source code
with multiple versions of Qt then connect() to this function using
pointer to member function and update the slot's parameter type if
needed.

bb0a616260 QObject: overhaul narrowing detection
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
when calling QObject::connect() when
QT_NO_NARROWING_CONVERSIONS_IN_CONNECT now takes also
into account user-defined implicit conversions that undergo
through a narrowing conversion.

bfb9b02d3b QCborValue: fix the move-assignment operator
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.

f14559790b Change qHashBits to use MurmurHash2
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.

5b7c3e31b5 New QHash implementation
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,

549712830b QProperty: Add support for member function change handlers
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.

44ceb56455 QFuture - add ability to move results from QFuture
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.

f3ce9e9332 Make QPropertyBindingPrivate accessible to QtQml
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.

02d595946f QCborValue::fromCbor: Apply a recursion limit to decoding
A simple 16k file can produce deep enough recursion in Qt to cause stack
overflow. So prevent that.

I tested 4096 recursions just fine on my Linux system (8 MB stack), but
decided 1024 was sufficient, as this code will also be run on embedded
systems that could have smaller stacks.

[ChangeLog][QtCore][QCborValue] fromCbor() now limits decoding to at
most 1024 nested maps, arrays, and tags to prevent stack overflows. This
should be sufficient for most uses of CBOR. An API to limit further or
to relax the limit will be provided in 5.15. Meanwhile, if decoding more
is required, QCborStreamReader can be used (note that each level of map
and array allocates memory).

737fe89691 Q{File,FileInfo,Dir}: add std::filesystem::path overloads
Add some overloads where (I thought) it makes sense for QDir and QFile
to accept std::filesystem::path objects. Currently my thinking is to
not add overloads for static functions where std::filesystem can already
do the same job, e.g. create directory or file.

Template and enable_if is needed due to both QString and
std::filesystem::path being able to be constructed from string literals.

The common shared code is currently in QFile because QDir had an
implicit include of QFile, made explicit in this patch, and QFileInfo
has an include to QFile as well.

The QT_HAS_STD_FILESYSTEM macro is visible in user-code which I
currently take advantage of in the tests, and users could too.

QSet and std::(unordered_)set were so far not treated as appendable, as

We achieve this by testing for and using the insert method. While vector
has also such a method, it doesn't take a single value, but rather a
position or iterator + value, so the template specialization is not
ambiguous.

733ae8a04b Make it possible to use QTaggedPointer within classes
A common pattern in declarative is to use the unused bits in linked list
next pointers for additional information storage. The "next" pointer is
typically then a tagged pointer of the containing class, which is not
fully defined yet. Therefore alignof() can't be used at tagged pointer
instantiation time. This patch delays the calls to alignment, etc. until
the corresponding functions are used, as in principle the tagged pointer
is just a quintptr and no additional information should be needed until
operating on it.

dfaca09e85 Add support for attaching continuations to QFuture
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.

[ChangeLog][QtCore] Added support for attaching continuations to QFuture.

728cc964f3 QString/QByteArray: make all symmetry-checked member-compare() combinations noexcept
In QByteArray, they were just not marked as such.

In QString and QStringRef, the implicit conversion from QChar to
QString would destroy it. Add a QChar overload, delegating to
QStringView.

Added docs for the new overloads, copying from the nearest neighbor so
as to not look out of place. All string classes use different wording
for these functions. A cleanup of this state of affairs is out of the
scope of this patch.

ef92ac5636 QLibrary: stop setting errorString after resolve()
resolve() is technically thread-safe if the library has been loadaed. We
don't promise that, but it's there. More importantly, because
QLibraryPrivate is shared among QPluginLoader and QLibrary that point to
the same file, we can't thread-safely set the error string.

[ChangeLog][Important Behavior Changes] QLibrary::resolve() will no
longer set or clear the error string based on the success of finding the
symbol. The error string will reflect the result of loading the library.

981c1fe15f QDebug::toString(): use nospace()
The intended use cases for toString() are the situations where you
can't use operator<<, such as QVERIFY2, Q_ASSERT_X, etc., which means
that it will often be used as an argument to e.g. QString::arg(), where
the user has control over the structure of the message. For that
reason, adding an extra space to the end is not necessary and just gets
in the way.

of one of the relevant formats. A valid date or time will still be
parsed, even if the other part of the content is invalid, as long as
it (and any offset, if present) has the right form. In particular, the
parser now rejects texts with trailing cruft (other than space).

e5acaa12e3 QObject: treat T* -> bool conversions as narrowing
Following wg21.link/LWG3228, it was found that a proper variant fix
requires that T* -> bool conversions be treated as narrowing
conversions in subclause wg21.link/dcl.init.lst. wg21.link/P1957R2 was
accepted in Prague 2020 as a DR and retroactively applies to older C++
standards.

Since we hard-code the algorithm of [dcl.init.lst], we can and must
add this manually.

QT_NO_NARROWING_CONVERSIONS_IN_CONNECT, pointer
(incl. pointer-to-member) to bool conversions are now considered
narrowing. This matches the resolution of a defect report in C++

ed2b110b6a Allow surrogate pairs for various "single character" locale data
Extract the character in its proper unicode form and encode it in a
new single_character_data table of locale data. Record each entry as
the range within that table that encodes it. Also added an assertion
in the generator script to check that the digits CLDR gives us are a
contiguous sequence in increasing order, as has been assumed by the
C++ code for some time. Lots of number-formatting code now has to take
account of how wide the digits are.

This leaves nowhere for updateSystemPrivate() to record values read
from sys_locale->query(), so we must always consult that function when
accessing these members of the systemData() object. Various internal
users of these single-character fields need the system-or-CLDR value
rather than the raw CLDR value, so move QLocalePrivate's methods to
supply them down to QLocaleData and ensure they check for system
values, where appropriate first.

This allows us to finally support the Chakma language and script, for
whose number system UTF-16 needs surrogate pairs.

Costs 10.8 kB in added data, much of it due to adding two new locales
that need surrogates to represent digits.

[ChangeLog][QtCore][QLocale] Various QLocale methods that returned
single QChar values now return QString values to accommodate those
locales which need a surrogate pair to represent the (single
character) return value.

e541a3f099 QTranslator: Expose language of translation file
This allows for instance to show the current UI language in the UI,
or to load additional translations that match the .qm file by other
means.

This is especially useful in the case of QTranslator::load(QLocale(),
...), in which case different language and country combinations might
be tried.

Another option is to inspect the file name via QTranslator::filePath();
however, this is more error-prone, and might also miss information
(if the .qm file name doesn't have a country suffix, or no suffix at
all).

e79979ba40 On Windows 7, fall back to SHFileOperation to avoid confirmation dialogs
Moving a file to the trash should preferably done via IFileOperation.
However, the implementation on Windows 7 ignores the operation flags
that request the shell not to show any confirmation dialogs or other UI
elements.

SHFileOperation is an old API that doesn't show any UI, but has the
limitation that it doesn't report the location of the file in the trash
after the move. So an application cannot restore the file, but the user
can do so via Explorer.

Overall, the better compromise is to not have dialogs at the expense of
not being able to report the new path. This allows us to run the unit
test on Windows 7 as well.

74a2467edd Add QFile::moveToTrash, which moves a file to the trash
Due to the nature of QFile just operating on a file path, this also
works for paths that are actually directories.

The test covers files from different locations on which this
operation should typically succeed, but tries to handle the case
where trashing files will fail because of the file system
structure.

On Windows 7, running the test will open a confirmation dialog as
the implementation of IFileOperation doesn't respect the various
flags. This might depend on the specific Windows 7 patch level,
and the option to always use SHFileOperation on that platform needs
to be evaluated further.

applications to move files to the trash.

internal APIs depend on other internal APIs.

Short of bootstrapping much of QtCore into this test case, the only
sensible option is to remove this test case again, and cover the

At the same time, address those failures that were discovered
on platforms that could build the test, and fix compilation on

4e7af2061e Merge remote-tracking branch 'origin/wip/cmake' into dev
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.

71fa90a37c Enable system locale to skip digit-grouping if configured to do so
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.

d5bb8d5150 Preserve the case of the exponent separator CLDR supplies
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).

[ChangeLog][QtCore][QLocale] QLocale::exponential() now preserves the
case of the CLDR source, where previously it was lower-cased.

601ce9e08a Implement moving of a single file system entry to the trash
This implements the operation for Windows, macOS, and Unix, for now
only as a private API (since QFileSystemEngine is private). This adds
the capability as a testable function; public API to be agreed on and
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.
