QList::insert() should never need to call a destructor. This
requires that we construct the new items in the list in order
and increment the size each time we constructed a new item.
Not having a code path that potentially calls destructors should
avoid the generation of lots of additional code for those
operations. In addition, the forward and backwards code paths
are now unified and only require somewhat different setup of
some variables at the start.
This gives us strong exception safety when appending one item,
weak exception safety in all other cases (in line with std::vector).

Types that throw in their destructors are strongly discouraged in C++,
and even the STL doesn't define what happens if such types are stored
in their containers.
Make this more explicit for Qt and disallow storing those types in our
containers. This will hopefully preempty any potential future bug
reports about us not handling such a case. It also helps simplify
some code in QList and other cases and makes it possible to explicitly
mark more methods as noexcept.
Some care needs to be taken where to add the static asserts, so that
we don't disallow forward declarations of types stored in containers.
Place the static assert into the destructor of the container where
possible or otherwise into the templated d-pointer.

QChar should not be convertible from any integral type except from

David provided the perfect example:
if (str == 123) { ~~~ }
compiles, with 123 implicitly converted to QChar (str == "123"
was meant instead). But similarly one can construct other
scenarios where QString(123) gets accidentally used (instead of
QString::number(123)), like QString s; s += 123;.
Add a macro to revert to the implicit constructors, for backwards
compatibility.
The breaks are mostly in tests that "abuse" of integers (arithmetic,
etc.). Maybe it's time for user-defined literals for QChar/QString,
but that is left for another commit.

sacrificing much:
1. append-only use cases should have the same performance as before
2. prepend-only use cases should (with the help of other commits) get
additional performance speedup
3. mid-insertion is harder to reason about, but it is either unchanged
or benefits a bit as there's some free space at both ends now
4. mixed prepend/append cases are weird and would keep excess free
space around but this is less critical and overall less used AFAIK
Now, QList would actually start to feel like a double-ended container
instead of "it's QVector but with faster prepend". This commit should
help close the performance gap between 6.0 and 5.15 as well

Use std::hypot() instead of sqrt() of a sum of squares.
This ensures length() can't be zero when isNull() is false.
Use length() in QLine::setLength() rather than duplicating that.
Clarify and expand some documentation; isNull() never said what
constituted validity, nor did unitVector() mention that is should not
be used on a line for which isNull() is true. Make clear that lines of
denormal length cannot be rescaled accurately.
Given that we use fuzzy comparison to determine equality of
end-points, isNull() can be false for a line with displacements less
than sqrt(numeric_limits<qreal>::denorm_min()) between the coordinates
of its end-points (as long as these are not much bigger); squaring
these would give zero, hence a zero length, where using hypot() avoids
the underflow and gives a non-zero length. Having a zero length for a
line with isNull() false would lead to problems in setLength(), which
uses an isNull() pre-test, protecting a call to unitVector().
(It was already possible for a null line to have non-zero length; this
now arises in more cases.)
Restored QLine::setLength() to the form it had before a recent change
to avoid division by zero (which resulted from underflow in computing
the length of a non-null line) but allow for the possibility that the
unit vector it computes as transient may not have length exactly one.
Add tests against {ov,und}erflow problems in QLine. Reworked the test
added during the divide-by-zero fix to make it part of the existing
test.

Extended existing tests with QArrayData's allocation options
Added extra tests on array operations covering append, insert,
emplace, erase and truncate. "Raw" QArrayDataPointer is used instead of
test-specific SimpleVector to check the behavior without some custom
logic in-between
The change targets future updates to array operations in the light of
prepend optimization: as the array operations would become more complex,
these tests should give a much better coverage (specifically due to
likely non-trivial implementation details and optimizations)

... and QMultiMap as std::multimap.
Just use the implementation from the STL; we can't really claim that
our code is much better than STL's, or does things any differently
(de facto they're both red-black trees).
Decouple QMultiMap from QMap, by making it NOT inherit from
QMap any longer. This completes the deprecation started in 5.15:
QMap now does not store duplicated keys any more.
Something to establish is where to put the
QExplictlySharedDataPointer replcement that is in there as an
ad-hoc solution. There's a number of patches in-flight by Marc
that try to introduce the same (or very similar) functionality.
Miscellanea changes to the Q(Multi)Map code itself:
* consistently use size_type instead of int;
* pass iterators by value;
* drop QT_STRICT_ITERATORS;
* iterators implictly convert to const_iterators, and APIs
take const_iterators;
* iterators are just bidirectional and not random access;
* added noexcept where it makes sense;
* "inline" dropped (churn);
* qMapLessThanKey dropped (undocumented, 0 hits in Qt, 1 hit in KDE);
* operator== on Q(Multi)Map requires operator== on the key type
(we're checking for equality, not equivalence!).
Very few breakages occur in qtbase.
[ChangeLog][Potentially Source-Incompatible Changes] QMap does not
support multiple equivalent keys any more. Any related functionality
has been removed from QMap, following the deprecation that happened
in Qt 5.15. Use QMultiMap for this use case.

Make QPair an alias for std::pair, and qMakePair just a forwarder
towards std::make_pair.
Why? Fundamentally to ditch a bunch of NIH code; gain for free
structured bindings, std::tuple and std::reference_wrapper
compatibility, and so on.
Breakages:
* Some that code manually forward declares QPair.
We don't care about it (<QContainerFwd> is the proper way).
* Some code that overloads on std::pair and QPair. Luckily
it's mostly centralized: debug, metatypes, testing macros.
Just remove the QPair overload.
* Usages of qMakePair forcing the template type parameters.
There are a handful of these in qtbase, but only one was actually
broken.
* std::pair is NOT (and will never likely be) trivially copiable.
This is agreed to be a mistake done by practically all implementations
in C++11, can can't be fixed without breaking ABI.
Some code using QPair assuming it's trivially copiable may break;
exactly one occurrence was in qtbase.
* QMetaType logic extracts the type names in two different ways,
one by looking at the source code string (e.g. extracted by moc)
and one via some ad-hoc reflection in C++. We need to make
"QPair" (as spelled in the source code) be the same as "std::pair"
(gathered via reflection, which will see through the alias)
when compared. The way it's already done e.g. for QList is
by actually replacing the moc-extracted name with the name
of the actual type used in C++; do the same here.
On libc++, std::pair is actually in an inline namespace --
i.e. std::__1::pair; the reflection will extract and store
"std::__1::pair" so we need an ad-hoc fix to QMetaType.
[ChangeLog][QtCore][QPair] QPair is now an alias to std::pair,
and does not exist as a class in Qt any more. This may break
code such as functions overloaded for both QPair and std::pair.
Usually, the overload taking a QPair can be safely discarded,
leaving only the one taking a std::pair. QPair API has not changed,
and qMakePair is still available for compatibility (although
new code is encouraged to use std::pair and std::make_pair
directly instead).

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

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:

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

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.

- Replaced the usages of:
* QDateTime::toTime_t() -> QDateTime::toSecsSinceEpoch().
* QDateTime::fromTime_t() -> QDateTime::fromSecsSinceEpoch().
* QDate::shortDayName() -> QLocale::system().dayName().
* QTime by QElapsedTimer, where the deprecated methods of QTime
were used.
- Modified the tests for the deprecated methods to be enabled only
when the corresponding methods are enabled: when the deprecated
APIs are disabled, the tests will be also disabled, and the
compilation won't be broken.

Semi-automated, just needed ~20 manual fixes:

$ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)store\(/$1storeRelaxed\(/g' -i \{\} +
It can be easily improved (e.g. for store check that there are no commas
after the opening parens). The most common offender is QLibrary::load,
and some code using std::atomic directly.

The code made two incorrect assumptions: that the strings used are "AM"
or "PM", or would be translated. Instead, the locale provides the
correct strings, and there is no need to translate. However, in order
not to break existing translations, we give those preference.
And that the AM/PM string is not longer than 4 characters, while in
e.g Spanish/Columbia locale the strings are "A. M." and "P. M.", ie 5
characters long. Also, the use of qMin in a function that is asked to
provide the maximum section length is wrong.
[ChangeLog][QWidgets][QDateTimeEdit] Use the information provided by
the locale to determine the AM/PM strings, unless they are already
translated.

... spotted with the brand-new checks for that in QCharRef.
The rx[i] == ~~~ check is clearly wrong, as rx is the regexp
we're building and `i` was not supposed to index into it.
The intended meaning was wc[i] == ~~~, testing if we were seeing
the closing bracket of a character set. We need to check for
that immediately for dealing with the special syntax of []...] where
the ] belongs to the character set (it can't be the closing one
as character sets cannot be empty).
Fix and add a regression test. Bonus: this code was almost
unchanged since 2009.

Includes a fixup for 03fadc26e7, which
removed the check on empty transition list, needed when no data are
available. Ensured that such a data-free zone would in fact be
noticed as invalid during init().
Fixed handling of times before the epoch (we still want to consult a
POSIX rule, if that's all that's available) while ensuring we (as
documented) ignore DST for such times.
Fixed handling of large times (milliseconds since epoch outside int
range) when looking up POSIX rules. Gave QTimeZonePrivate a YearRange
enum (to be moved to QTimeZone once this merges up to dev) so as to
eliminate a magic number (and avoid adding another). Moved
year-munging in POSIX rules after the one early return, which doesn't
need the year range.
Added test-cases for the distant past/future (just checking UTC's
offsets; SLES has a minimal version of the UTC data-file that triggers
the bugs fixed here for them).
