Andrei Golubev e35d0ae0cc Support GrowsBackwards flag in QArrayDataPointer
Introduced allocation function in QArrayDataPointer with
interface similar to QArrayData::allocate that supports growing
strategies. This func is used instead of the original in cases
when prepend-aware storage is needed. Tried to follow Qt5 QList
policy in terms of space reservation

Updated QPodArrayOps::reallocate to be aware of growing
shenanigans. It doesn't look like a perfect solution but it is
rather close and similar to what Qt6 QList is doing when not
growing (e.g. reserve/squeeze)

Added initial QCommonArrayOps with helper function that tells
when reallocation is preferable over just using the insert-like
operation. This comes up later on when GrowsBackwards policy is
properly supported in operations

Essentially, 2/3 main data management blocks for prepend optimization
are introduced here. The last one being a generalized data move that
is done instead of reallocation when existing free space is not enough

Lars Knoll acbf9a858b Cleanup QTypeInfo
Remove QTypeInfo::isStatic, as that's not used anymore in Qt 6.
Also remove sizeOf, it's unused, and we have QMetaType for that if
required.
Remove all typeinfo declaractions for trivial types, as the default
template covers them correctly nowadays.

Finally set up a better default for isPointer, and do some smaller
cleanups all over the place.

Lars Knoll 1697fbdf05 Deprecate the static int based API in QMetaType
And remove one of the type id to name mapping that still
existed in QMetaType. QMetaTypeInterface can provide that,
so there's no need to have a second copy of the data.

qMetaTypeTypeInternal() can still map all the names of all
builtin types to ids. That functionality is for now still
required by moc and can't be removed yet.

Giuseppe D'Angelo 2ba1d540e6 QMultiMap: fix remove(Key, T) when key/value belong to the map
Just like any other container, it's legitimate for the user to
pass key/values belonging to the same container.
Q(Multi)Map::remove(Key) are already safe (either they call
erase() directly on std::(multi)map, where it does the right thing,
or they skip elements while detaching).
However, QMultiMap::remove(Key, T) wasn't safe in this regard
(the implementation is hand rolled), so take copies before start
erasing.

Andrei Golubev 56f1208f9e Separate exception safety primitives from operations
Refactored certain bits of qarraydataops.h: picked exception-related
building blocks and put them into one place, (somewhat) documented
the usage, added tests

Personally, the existing code seemed rather complicated to analyze
(and do mental experiments for corner cases), especially when staring
at the whole thing for a while or "returning back" from some other work
and I still have my doubts that everything works correctly. Testing the
building blocks that are used should:
a) increase trust into existing code (provided the usage is correct)
b) give more use cases of how to use the building blocks, which in turn
   would allow to compare and contrast tests vs implementation

Andrei Golubev 48911869cb Extend array operations tests with extra cases
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)

Giuseppe D'Angelo 14090760a8 Long Live QMap as a refcounted std::map!
... 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.

[ChangeLog][Potentially Source-Incompatible Changes] QMap and
QMultiMap iterators random-access API have been removed. Note that
the iterators have always been just bidirectional; moving
an iterator by N positions can still be achieved using std::next
or std::advance, at the same cost as before (O(N)).

[ChangeLog][Potentially Source-Incompatible Changes] QMultiMap does
not inherit from QMap any more. Amongst other things, this means
that iterators on a QMultiMap now belong to the QMultiMap class
(and not to the QMap class); new Java iterators have been added.

Giuseppe D'Angelo 8e98a161e9 Long live std::pair!
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).

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...)

Lars Knoll 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.

Lars Knoll 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,
measured with gcc on Linux:

instantiation time. This patch delays the calls to alignment, etc. until

Ulf Hermann 2145cdc54d Core: Provide comparison functions for QTypeRevision
The unspecified segment is between 0 and 1. This is because
QTypeRevision::zero(), as the default revisision needs to be smaller
than any other. At the same time we want explicitly specified non-zero
revisions to be larger than unspecified ones. Breaking this down on a
per segment level gives us the order shown here.

Alexandru Croitor 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.

The Mutable flag now contains the information on whether the data this

immutability setting from the allocation and from the type of data,
opening the way for mutable raw or foreign data.

There are still plenty of places in the source code that check the

this will require reviewing all the code, so is left for later.

The needsDetach() function is moved to QArrayData and
de-constified. It returns true when a reallocation is necessary if the

 - allocated data type: regular data done via heap allocation

The QArrayData object is usually allocated on the heap, unless its own

object should have a type of RawDataType, since we can't call free().

Marc Mutz e99b0016e8 Eradicate Q_FOREACHs over QVarLengthArray
There is no excuse for copying several KiBs of data just to iterate
over it, yet that's exactly what Q_FOREACH does.

Besides, this use of Q_FOREACH is being deprecated. In my tree, it's
already a hard error.

Lars Knoll 06456873fc Get rid of QT_STRICT_ITERATORS
The concept was a nice idea to avoid accidental detach() calls
in implicitly shared containers, but it conflicts with a C++11
compatible API for them, with signatures for modifying methods
taking a const_iterator as argument and returning an iterator
(e.g. iterator erase(const_iterator)).

Lars Knoll 5357231c0a Make QList an alias to QVector
This is almost 100% source compatible with Qt 5. Exceptions are

* Stability of references for large or non movable types
* taking a PMF for types that are now overloaded with r-value references
  in QVector
* The missing prepend optimization in QVector (that is still planned
  to come for Qt 6)

Volker Hilsheimer 226a60baf5 Replace Q_ALIGNOF usage in qtbase with C++11 alignof keyword
The macro is not documented, so not part of the public Qt API. It is
made obsolete by the alignof keyword in C++11.

Remove the usage of the macro across qtbase, in particular the
workarounds for compilers that didn't support alignof, and that will
not be supported in Qt 6.

Alexandru Croitor b6e75ff3ea Regenerate qtbase after wip/qt6 -> wip/cmake merge
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.

Milian Wolff 014d7ac654 Q{Shared,Weak}Pointer: Reduce overload sets in implicit conversions
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.
