7905b624fd QTextStream: fix streaming of char16_t's
Clazy complains about all uses of QLatin1Char these days, but if one
actually applies the fixit to turn

   out << QLatin1Char(' ');

into

   out << u' ';

the space is now streamed as an int (20), not as a space.

Fix by providing an explicit char16_t overload.

[ChangeLog][QtCore][QTextStream] Added op<<(char16_t).

[ChangeLog][Important Behavior Changes] QTextStream streams char16_t's
as QChars now instead of outputting the numeric value. If you want to
preserve the old behavior, cast the char16_t to a numeric type, such
as ushort or int, and stream that. This is backwards-compatible.

e48b4d2b7c Implement support for '0b' prefix in toInt() etc
[ChangeLog][QtCore][QByteArray/QByteArrayView/QLatin1String/QString/QStringView]
The string-to-integer conversion functions (toInt() etc) now support
the 0b prefix for binary literals. That means that base = 0 will
recognize 0b to mean base = 2 and an explicit base = 2 argument will
make toInt() (etc) skip an optional 0b.

[ChangeLog][QtCore][Important Behavior Changes] Due to the
newly-introduced support for 0b (binary) prefixes in integer parsing,
some strings that were previously rejected as invalid now parse as
valid. E.g., Qt 6.3 with autodetected bases would have tried to parse
"0b1" as an octal value and fail, whereas 6.4 will parse it as the
binary literal and return 1.

0b5b98c4ae Fix qlocale_unix's handling of uiLanguages to take script into account
Some languages have, in the same territory, locales for more than one
script. In such cases, since we ignored the script, we got the one
that is used by default, instead of the one actually asked for. Take
the script into account.

Added TODO comment in test listing the known examples of this;
manually tested before and after the fix to verify the prior code was
indeed getting it wrong and now does do it right.

7a7f2547f3 Return more specific entries before less in QLocale::uiLanguages()
The documentation overtly listed entries in this order but the code
gave less specific entries before more specific (and the tests
verified the same). This is now reversed.

[ChangeLog][QtCore][QLocale] uiLanguages() now prefers more specific
locale names over less specific ones, matching its own documentation,
except where the system backend supplies them in some other order.
This means a translation with the expected script and/or territory as
well as language will be used in preference to a generic one for just
the language, rather than only as a fall-back when the more generic
one is missing.

2b16997116 Clean up tst_QSettings::testVariantTypes()
Give the macro and its parameters clearer names, wrap the macro body
in do {...} while (0), use QCOMPARE() rather than QVERIFY()ing
comparisons, convert the result type to QMetaType::Type rather than
QVariant's deprecated equivalent, save one macro parameter by using
decltype() on another. Simplify one check by pulling out a common
sub-expression as a local variable.

In the process, give the settings keys meaningful names rather than
just "key" with a numeric suffix.

Ideally this test would be reworked to be data-driven, instead of
using macros, but the use of qvariant_cast<> to convert a read-back
value, along with the variable type of the input value compared to the
result of that cast, precludes this (as far as I can see).

makes sense, and I'm not doing it in this patch.

7de83f06c1 QDateTime: add conversions for time_point and zoned_time
In C++20, QDateTime is a direct equivalent of a sys_time<milliseconds>
time point. (Before, it might not have been, because system_clock before
C++20 was not guaranteed to be tracking Unix time, AKA UTC time without
leap seconds.) To be specific, sys_time<milliseconds> corresponds to
a QDateTime using the Qt::UTC timespec.

This patch:

1) adds named constructors taking time_points:

* a generic one taking any time_point convertible (via clock_cast) to
  a system_clock (this obviously includes system_clock, but also e.g.
  utc_clock)

* another couple taking local_time, interpreted as a duration from
  1/1/1970 in local time.

2) adds a named constructor from zoned_time (i.e. a sys_time + a
   timezone), that we can easily support via QTimeZone.

3) add conversion functions towards sys_time, matching the existing
   to(M)SecsSinceEpoch() functions.

[ChangeLog][QtCore][QDateTime] QDateTime can now be constructed
from std::chrono::time_point objects (including local_time), as
well as from std::chrono::zoned_time objects. Moreover, they
can be converted to std::chrono::time_point using system_clock
as their clock.

2e29f55f76 QDate: add conversions for std::chrono calendaring classes
std::chrono::year_month_day and related classes offer very
convenient to specify dates.

This patch adds implicit constructors to QDate to support this
convenience, e.g.:

  // YYYY-MM-DD, DD-MM-YYYY, MM-DD-YYYY formats:
  QDate d1 = 1985y / December / 8;
  QDate d2 = 8d / December / 1985;
  QDate d3 = December / 8d / 1985;

  // Indexed weekday:
  QDate d4 = 2000y / January / Monday[0];
  QDate d5 = 2000y / January / Monday[last];

and so on.

These are all implemented using the conversion from the std
calendaring classes to sys_days. Conversions between sys_days
and QDate are also added, since they're basically "for free".

I don't expect "ordinary" users to stumble upon it, but it's
worthy mentioning that std::chrono::year *does* have a year
zero (hence, year_month_day in year 0 or below are offset
by one with the corresponding QDate). I've left a note
in the documentation.

[ChangeLog][QtCore][QDate] QDate (and therefore QDateTime)
is now constructible using the year/month/day/week classes
available in the std::chrono library. Moreover, it now
features conversions from and to std::chrono::sys_days.

33c88f86b5 QAbstractProxyModel: do not access invalid indexes
QAbstractProxyModel::headerData tries to do the "smart" thing and
map sections in the proxy to sections in the source. However there's
no "mapSectionToSource" virtual. Instead, to map horizontal headers, the
code builds a proxy index at row 0 and section N, maps it to the source,
and finds out which source column it gets mapped to. (Same story
for the vertical headers).

... in general this can obviously fail, say you've got a "horizontal
scrambling" proxy model, but in the common case this is OK.

Except, if the proxy is empty (e.g. 0 rows or columns). In this case,
it asks for an illegal index, and if you reimplemented index() yourself
(which you must, since it's a pure virtual in QAPM) and you do bounds
checking, you'll not be pleased at the result.

This turns out to be a massive API liability. To fix this somehow properly,
we can decide that empty models don't get the section remapped (easy).
Less easy is the fact that, when the model does get some data, we have to
emit headerDataChanged() otherwise the views will get broken. So add
this logic too.

Note that QAPM does not normally forward any source model's signal -- a
subclass has to connect to them and handle them explicitly. That's
*another* API liability, all over the place -- data(), headerData(),
flags(), etc.

What I mean by this is that one can create a valid QAPM (by implementing
its pure virtuals) that however is immediately broken by the convenience
that QAPM provides for the rest (data(), headerData(), etc.).

This commit doesn't try and change this in any way, but I'm less and
less convinced of the usefulness of QAPM in its current shape.

it's meant to (e.g. a single-digit seconds field when format ss was

the minimum and maximum for the parser object failed, triggering an
assertion.

In any case, an invalid default-value wasn't useful to the code that
parsed a single section of the date-time string, so brute-force the
current value to a valid date-time (when possible) using the usual
round-trip via milliseconds since the epoch.

more informed by it, to exercise the same code-paths with fewer things

Calling Q[Multi]Hash::reserve(n) when n is much smaller than the
current amount of elements in the hash, could result in an infinite
loop, because at some point the algorithm could not find a free bucket
for the element.

Fixing it by returning early if the new desired capacity is less than
current.

4bc85b9850 QBuffer: fail early in seek() beyond QByteArray's max capacity
On 32-bit platforms, the range of qsizetype is smaller than the range
of the qint64 used as a parameter in seek().

When seek()ing beyond the current buffer's size, the old code relied
on a write() to fill the gap with NUL bytes. This has two problems:

First, this may allocate a huge amount of memory just to find that it
cannot write that much, possibly even taking the program down when the
allocation in the QByteArray ctor fails, instead of returning false from
seek().

Second, the QByteArray ctor to which we pass the gapSize only takes
qsizetype, not qint64, so we were writing data of size gapSize mod
(INT_MAX+1) on 32-bit platforms, which may succeed, just to find that
that wasn't the number of bytes we expected to be written. By that
time, however, the internal buffer has already been enlarged.

Fix by checking whether the desired seek position is within the limits
that QByteArray can contain early on, before attempting to construct
such a large QByteArray.

platforms when seek() fails due to position > INT_MAX.

61157c8354 QBuffer: fix writing more than two GiB of data
In Qt 6, QByteArray can hold more than two GiB of data on 64-bit
platforms, so QBuffer should be able to handle writes of more than two
GiB, too. But the implementation didn't check for overflow and held
sizes in int variables, so it happily reported success but wrote data
only mod INT_MAX.

Fix by carefully avoiding overflow and using size variables of proper
type.

6ec1dc904d QSettings: port key processing to QAnyStringView
... in preparation for replacing the QString keys in the public API
with QAnyStringView ones.

This removes the "important optimization" that avoids a detach in the
common case where the input is the same as the output of
normalization. But that optimization is beside the point, because it
trades a memory allocation avoided in the library for O(N) allocations
inserted into user code for each call to QSettings::value(), the vast
majority of which are calls with string literals.

With the public interface ported to QAnyStringView in the follow-up
patch, we can then internally optimize memory allocations _in a central
place_ (e.g. by returning std::u16string or QVarLengthArray<QChar> from
normalizeKey() instead of QString). But first we need to get rid of all
the unwarranted allocations in user code.

1b14569753 QMutexLocker: strenghten the locking operations
There is no reason to allow relock() on a locked locker, or unlock()
or an unlocked one, just like we don't allow that on a plain mutex
to begin with. The docs already said that e.g. relock() locks an
_unlocked_ locker.

[ChangeLog][QtCore][QMutexLocker] QMutexLocker allowed relock() and
unlock() on an already closed (resp. open) locker object. These
semantics have always been undocumented and are now unsupported
(in both cases they yield undefined behavior.)

1977c922e9 QFlatMap: make insertion STL-compatible
That is, insert() doesn't overwrite an existing entry, and range
insert inserts the first of equivalent keys' values, not the last.

This allowed this author to optimize the implementation of
makeUnique() to a O(N) algorithm (was: O(N²)). Said optimization would
have been possible with the old semantics, too, but I wrote the
algorithm first and only then noticed the broken insert() behavior is
present on QFlatMap, too, so I decided not to let good code go to
waste and to fix both problems at the same time.

In order to give users a hint of the changed semantics, make the new
API opt-in until Qt 6.5, so Qt 6.4 ships with the both the old and the
new semantics disabled, where they contradict.

is value in allowing QStringList, even though it works only on QL1S
needles (QStringView -> QString isn't implicit). But users may have
other types that for better or worse implicitly convert from views, so
we shouldn't over-constrain the function.

value_type. It no longer requires an exact match.

78073f8ab6 Restore C++20-deprecated mixed-enum bitwise operators
C++20 deprecated arithmetic on enum types. For enums used on QFlags<>,
these operators have always been user-defined, but when the two enums
are of different type, such as QFrame::Shape and QFrame::Shadow, the
deprecation warning pops up.

We have in the past fixed these in our headers by manual casts, but
that doesn't help our users when our API requires them to OR together
enums of different type.

Until we can rework these APIs to use a variadic QFlags type, we need
to fix it in an SC and BC way, which is what this patch sets out to
do.

The idea is simply to mark pairs of enums that are designed to be ORed
together and replace the deprecated built-in bitwise operators with
user-defined ones in C++20. To ensure SC and BC, we pass an explicit
result type and use that to check, in C++17 builds, that it matches
the decltype of the result of the built-in operator.

This patch is the first in a series of similar patches. It introduces
said markup macro and applies it to all enum pairs that create
warnings on (my) Linux GCC 11.3 and Clang 10.0.0 builds. It is
expected that more such markups are needed, for other modules, and for
symmetry.

Even with this patch, there is one mixed-enum warning left, in
qxcbwindow.cpp. This appears to be a genuine bug (cf. QTBUG-101306),
so this patch doesn't mark the enums involved in it as designed to be
used together.

This patch also unearthed that QT_TYPESAFE_FLAGS, possibly
unsurprisingly so, breaks several mixed bitwise flags-enum operations
(QTBUG-101344).

d743fd0d0a qDecodeDataUrl(): treat ";base64" marker as case-insensitive
RFC2397 doesn't explicitly mention it, but references RFC2045, which,
in Section 2, states:

> All media type values, subtype values, and parameter names as
> defined are case-insensitive.

and goes on, in 6.1:

>   mechanism := "7bit" / "8bit" / "binary" /
>                  "quoted-printable" / "base64" /
>                  ietf-token / x-token
>
>   These values are not case sensitive

So regardless of whether "base64" is a parameter name, or a mechanism,
we need to treat it case-insensitively.

Use QLatin1String::endsWith() instead of QByteArray::endsWith(),
because the former takes Qt::CaseInsensitive while the latter would
need a toLower().

Add a test.

As a drive-by, use the same trick for the existing case-insensitive
comparison with "charset".

As a further drive-by, fix inappropriate uses of QLatin1String (=
where they don't prevent allocations).

[ChangeLog][QtCore][QUrl] Now recognizes the ";base64" marker in
"data:" URLs case-insensitively.

ba6c1d2785 QProperty: fix threading issues
QObject's cache the binding status pointer to avoid TLS lookups.
However, when an object is moved to a different thread, we need to
update the cached pointer (as the original thread might stop and thus no
longer exist, and to correctly allow setting up bindings in the object's
thread).
Fix this by also storing the binding status in QThreadPrivate and
updating the object's binding status when moved. This does only work
when the thread is already running, though. If it is not running, we
instead treat the QThreadPrivate's status pointer as a pointer to a
vector of pending objects. Once the QThread has been started, we check
if there are pending objects, and update them at this point.

1931689c7d tst_qstringapisymmetry: check QString/QAnyStringView overloads w/Q_WEAK_OVERLOAD flipped
This overload set may come in handy to cushion some of the concerns
regarding replacing QString functions with QAnyStringView ones.

Overloading with a Q_WEAK_OVERLOAD QAnyStringView function requires
users to jump through hoops in order to avoid the QString overload,
but with the Q_WEAK_OVERLOAD roles reversed, the QAnyStringView
overload becomes the preferred version, relegating the QString
overload to a fall-back to facilitate sharing where it makes sense
(e.g. for QObject::setObjectName()).

0deff80eab Associative containers: add a way to obtain a key/value range
Our associative containers' iterator's value_type isn't a destructurable
type (yielding key/value). This means that something like

  for (auto [k, v] : map)

doesn't even compile -- one can only "directly" iterate on the
values. For quite some time we've had QKeyValueIterator to allow
key/value iteration, but then one had to resort to a "traditional" for
loop:

  for (auto i = map.keyValueBegin(), e = keyValueEnd(); i!=e; ++i)

This can be easily packaged in an adaptor class, which is what this
commmit does, thereby offering a C++17-compatible way to obtain
key/value iteration over associative containers.

Something possibly peculiar is the fact that the range so obtained is
a range of pairs of references -- not a range of references to pairs.
But that's easily explained by the fact that we have no pairs to build
references to; hence,

 for (auto &[k, v] : map.asKeyValueRange())

doesn't compile (lvalue reference doesn't bind to prvalue pair).
Instead, both of these compile:

  for (auto [k, v] : map.asKeyValueRange())
  for (auto &&[k, v] : map.asKeyValueRange())

and in *both* cases one gets references to the keys/values in the map.
If the map is non-const, the reference to the value is mutable.

Last but not least, implement pinning for rvalue containers.

[ChangeLog][QtCore][QMap] Added asKeyValueRange().
[ChangeLog][QtCore][QMultiMap] Added asKeyValueRange().
[ChangeLog][QtCore][QHash] Added asKeyValueRange().

6f5c78fe3d QFlatMap: add remove_if
The existing API of QFlatMap did not allow efficient removal of
elements:

- std::remove_if does not apply, because it works by moving elements
  back in the range onto those that need to be removed, which doesn't
  work in flat_map's case, because, like for all associative
  containers, the key in value_type is const.

- The node-based erase-loop (over it = cond ? c.erase(it) :
  std::next(it)) works, but, unlike in traditional associative
  containers, is quadratic, because flat_map::erase is a linear
  operation.

According to Stepanov's principle of Efficient Computational Basis
(Elements of Programming, Section 1.4), we're therefore missing API.

Add it.

I couldn't make up my mind about the calling convention for the
predicate and, despite having authored a merged paper about erase_if,
can never remember what the predicate is supposed to take, so be fancy
and accept all: (*it), (it.key(), it.value()), (it.key()). This means
that unary predicates can either not be generic or must be properly
constrained to distinguish between pair<const K, V> and K, but that's
not necessarily a bad thing.

There's no reason to supply a Qt-ified removeIf on top of the standard
name, because this is private API and doubling the names would do
nothing except double the testing overhead.

Commit 35adb74ddd ("Reimplement JSON

stored in the QJsonObject::iterator. The same mistake was propagated
when QJsonObject::iterator was converted to QJsonValueRef. This had no
ill effects because the o->elements container would always contain more
elements, but it meant the check was ineffective and meant nothing.

So instead of doing nothing when the iterator does not point to this
container, simply assume it does. Bad things will happen if you try to
erase an iterator that points to another container, but that's true for
almost all container/iterator mechanisms.

04dc959d49 Introduce Q{Json,Cbor}ValueConstRef
I screwed up when I wrote QCborValueRef by not having the ConstRef
type. The code worked, but it wasn't const-correct, allowing you to
write:

  const QCborArray &arr = something();
  *arr.begin() = QCborArray();

This mistake was brought over to QJsonValue in Qt 6.0, so it has to be
fixed for QJsonValue too. The actual fixes are in the next couple of
commits.

This change is believed to be binary-compatible: the Q{Json,Cbor}ValueRef
classes continue to have the exact same size, except that they're now
empty and have a new base class. They weren't trivial before this commit
doesn't change that.

[ChangeLog][Potentially Source-Incompatible Changes] The iterator
classes for Qt's JSON and CBOR containers (array and map/object) had a
const correctness issue which allowed a const_iterator to mutate the
container being iterated on, even if that container was itself const. Qt
6.4 has a fix for this, but will cause compilation issues where
QCborValueRef and QJsonValueRef were used where the correctness could be
violated. To keep code compiling with both 6.3 and 6.4, either change to
non-const iteration or replace the QxxxValueRef with a const QxxxValue
reference. This change is binary-compatible.

b55f10b2a0 Convert a table iteration to use ranged-for
The loop used an int counter that was initialized from a size_t,
provoking a warning from MSVC. Since the indexing is irrelevant in any
case, use a ranged-for loop. Since the loop was formerly in decreasing
index order, reverse the table being iterated so that entries remain
in their prior order.

21ce257b6c Repair tst_qcoreapplication to not segfault on Android
tst_qcoreapplication.cpp is used both in tst_qcoreapplication and
tst_qguiapplication. To distinguish these two compilations,
the define QT_GUI_LIB was used. This led to an error on Android,
where Qt::Gui is always linked, because the Qt Android Platform
Plugin needs it.
This patch introduces the preprocessor define QT_QGUIAPPLICATIONTEST
which is to be used only in the compilation of tst_qguiapplication.
This is then used instead of QT_GUI_LIB.

29fceed2ff QProcess/Unix: ensure we don't accidentally execute something from CWD
Unless "." (or the empty string) is in $PATH, we're not supposed to find
executables in the current directory. This is how the Unix shells behave
and we match their behavior. It's also the behavior Qt had prior to 5.9
(commit 28666d167a). On Windows, searching
the current directory is the norm, so we keep that behavior.

This commit does not add an explicit check for an empty return from
QStandardPaths::findExecutable(). Instead, we allow that empty string to
go all the way to execve(2), which will fail with ENOENT. We could catch
it early, before fork(2), but why add code for the error case?

See https://kde.org/info/security/advisory-20220131-1.txt

[ChangeLog][Important Behavior Changes] When passed a simple program
name with no slashes, QProcess on Unix systems will now only search the
current directory if "." is one of the entries in the PATH environment
variable. This bug fix restores the behavior QProcess had before Qt 5.9.
If launching an executable in the directory set by setWorkingDirectory()
or inherited from the parent is intended, pass a program name starting
with "./". For more information and best practices about finding an
executable, see QProcess' documentation.

ec03db7bb3 Fix C++20 ambiguous relational operators between QJsonValue{,Ref}
In C++20, any given relational operator is also considered in its
reversed form, so e.g.

   given op==(X, Y)
   and X x, Y y, then y == x will compile, by using the reversed op(X, Y)

This, unfortunately, makes some existing asymmetric operator overload
sets ambiguous, and instead of applying tie-breaker rules, at least
Clang is warning about these.

For us, this means we need to make our overload set non-ambiguous. The
QJsonValue{,Ref} classes failed this, because they only provide the
following member-operators:

- QJsonValue::op==(const QJsonValue&) const
- QJsonValueRef::op==(const QJsonValue &) const

For member functions, there are no implicit conversions on the LHS. So
in C++17, we have a nice dichotomous overload set:

- LHS is QJsonValue -> use QJsonValue::op==(QJsonValue)
- LHS is QJsonValueRef -> use QJsonValueRef::op==(QJsonValue)

In both of these, it the RHS is a QJsonValueRef, it's implicitly
converted to QJsonValue for the call.

Enter C++20, and the reversed signatures are suddenly available, too,
which is a problem for QJsonValueRef <> QJsonValueRef, which could be
resolved, as in C++17, using

  lhs.QJVR::op==(QJV(rhs))

or it could now be

  rhs.QJVR::op==(QJV(lhs)); // reversed

Says Clang 10:

  tst_qtjson.cpp:990:5: warning: ISO C++20 considers use of overloaded operator '==' (with operand types 'QJsonValueRef' and 'QJsonValueRef') to be ambiguous despite there being a unique best viable function [-Wambiguous-reversed-operator]
    CHECK(r0, a0, r1);
    ^     ~~      ~~
  qjsonvalue.h:189:17: note: ambiguity is between a regular call to this operator and a call with the argument order reversed
    inline bool operator==(const QJsonValue &other) const { return toValue() == other; }
                ^

A similar argument makes op!= ambiguous.

Says Clang 10:

  tst_qtjson.cpp:988:5: error: use of overloaded operator '!=' is ambiguous (with operand types 'QJsonValueRef' and 'QJsonValueRef')
    CHECK(r0, r0, r1);
    ^     ~~  ~~
  qjsonvalue.h:190:17: note: candidate function
    inline bool operator!=(const QJsonValue &other) const { return toValue() != other; }
                ^
  qjsonvalue.h:189:17: note: candidate function
    inline bool operator==(const QJsonValue &other) const { return toValue() == other; }
                ^
  qjsonvalue.h:189:17: note: candidate function (with reversed parameter order)

To fix, provide the missing operators as free inline functions (so Qt
6.2 and 5.15 don't get new symbols added) so there's always exactly
one best match.

This is a fix for 6.2 and 5.15. At the time of writing, 6.3 isn't
released, yet, so there, we could QT_REMOVED_SINCE the pre-existing
member operators in favor of hidden friends (as per QTBUG-87973).

Use C++17'isms to prevent an automatic merge to 5.15, which requires

   contains(QT_CONFIG,c++2a):CONFIG += c++2a

added to tst_qtjson.pro.

830fd1908b Add some more QDate::{start,end}OfDay() tests
While investigating an assertion failure I noticed that the existing

Of course, we can't robustly test these time-specs, due to vagueries
of offset details and zone availability, but we can at least verify
that they return date-times on the specified date. Add a test-case for
the start of 1900, on which the assertions were first seen; it is the
earliest moment representable with tm_year >= 0, after all.

One of these tests fails on 6.2 but the fix for that (as opposed to
the the assertion) requires 6.3's improvements to the handling of
time_t's fuller range - too risky a change to pick back to 6.2.

9f31f579ec Sequential erase/_if: don't apply predicate twice to element
The code was trying to avoid a detach in the case no element needed to
be removed, by first running find_if() on const_iterators, and then,
after converting its result to (mutable) iterators, start the
remove_if() algorithm where find_if() left off.

But this applies the predicate to the element found by find_if() (if
any) _twice_: first just before we exit the first find_if() and then
just as we enter remove_if(), which will start by running find_if()
again, with the result of the initial find_if as 'first'.

Apart from being needlessly inefficient, this violates the
specification of Uniform Erasure, which defines sequential erase_if()
as being equivalent to remove_if() + container erase(), with the
former being specified to apply the predicate exactly once per
element.

Fix by writing the remove_if() part by hand.

Instead of doing the dance with the loop invariant documentation
twice, simply implement erase() via erase_if() (complicated a bit by
the weird passing of predicates by lvalue reference instead of by
value, as would be idiomatic). This exposes users to:

[ChangeLog][QtCore][Potentially Source-Incompatible Changes] A fix in
the implementation of the erase-like algorithms of sequential Qt
container may re-enable signed/unsigned comparison warnings previously
suppressed by having occurred in std library code. To fix, cast the
value to look for such that it has the same signedness as the
container's elements.

... but the issue would be the same had we inlined std::remove()
instead of passing a lambda to sequential_erase_if(), so it's nothing
we can, nor should, work around.

[ChangeLog][QtCore][Containers] Fixed a bug in the implementation of
most sequential Qt container's erase-like algorithms (member
removeAll()/removeIf() and free erase()/erase_if()) where the equality
operator or the predicate, respectively, was applied to the first
matching element twice. Each element is now tested exactly once.

577d698b8e changed QString::isUpper /
isLower behaviors to match Unicode semantics: a string is uppercase
if it's identical to its own toLower/toUpper folding. These semantics
come from Unicode so they're not up for debate.

That commit however left QByteArray untouched. Generally speaking, we
want to move away from QByteArray as "text storage" -- this has
partially happened between Qt 5 and Qt 6, where QByteArray went from
Latin-1 semantics to ASCII semantics. Still, QByteArray offers
toUpper/toLower and isUpper/isLower and all this family of functions
should be consistent in behavior.

Apply the same fix that was applied to QString.

[ChangeLog][Important Behavior Changes] The semantics of
QByteArray::isLower() and QByteArray::isUpper() have been changed. Now
lowercase (resp. uppercase) byte arrays are allowed to contain any
character; a byte array is considered lowercase (resp. uppercase) if
it's equal to its own toLower() (resp. toUpper()) folding. For instance,
the "abc123" byte array is now considered to be lowercase.
Previously, the isLower() (resp. isUpper()) functions checked whether
the byte array only contained ASCII lowercase (resp. uppercase)
characters, and was at least 1 character long. This had the side effect
that byte array containing ASCII non-letters (e.g. numbers, symbols,
etc.) were not lowercase nor uppercase.

[ChangeLog][QtCore][QByteArray] QByteArray::isLower() and
QByteArray::isUpper() now work correctly with empty byte arrays. The
semantics of these functions have been changed.

cce7e35253 Q(Static)ByteArrayMatcher: manage indexIn() overloads
Unlike QString and QStringView, QByteArrayView and QByteArray don't
overload well.

Solve the overload issue the usual way: by making the QByteArray one a
Q_WEAK_OVERLOAD. This is trivial for QStaticByteArrayMatcher, which
isn't exported, but require QT_REMOVED_SINCE magic for
QByteArrayMatcher, which is.

The additional const char* overload has shielded us from the worst
fall-out so far, it seems, but it makes for a truly horrible overload
set:

    matcher.indexIn(str, 3);

Q: Is the 3 here the length of the haystack or the value of the from
parameter?

A: It depends on decltype(str)!

If the (const char*, qsizetype, qsizetype=0) overload is the better
match, then 3 limits the haystack's length.

If, otoh, the (QByteArray(View), qsizetype) overload is the better
match, then it's the value of the from parameter.

As if this wasn't bad enough, QByteArray implcitly converts to const
char* by default!

A follow-up patch will therefore deprecate the (ptr, size) overloads,
so we de-inline the QByteArrayView ones to avoid having to touch the
implementation once more.

Found during 6.3 API review.

a8794503eb Fix memory leaks when capturing a QFuture in its continuation
Capturing a QFuture in the continuations attached to it results in
memory leaks. QFuture's ref-counted data can only be deleted when the
last copy referencing the data gets deleted. The saved continuation
that keeps a copy of the future (as in case of the lambda capture) will
prevent the data from being deleted. So we need to manually clean the
continuation after it is run. But this doesn't solve the problem if the
continuation isn't run. In that case, clean the continuation in the
destructor of the associated QPromise.

To avoid similar leaks, internally we should always create futures via
QPromise, instead of the ref-counted QFutureInterface, so that the
continuation is always cleaned in the destructor. Currently QFuture
continuations and QtFuture::when* methods use QFutureInterface directly,
which will be fixed by the follow-up commits.

d671bab0e3 Win32: always allow the event loop to be woken up by posted events
We set the wakeUps atomic to prevent multiple WM_QT_SENDPOSTEDEVENTS from
being posted. However, this might happen right after the event processing
thread cleared the atomic, but before it processed the previous
WM_QT_SENDPOSTEDEVENTS message. In that case, we end up with a set
atomic  and an empty event queue, resulting in the event loop to block
even though there are posted QEvents.

To prevent that, always reset the atomic when we handle the
WM_QT_SENDPOSTEDEVENTS message. In that case, we either call
sendPostedEvents, or startPostedEventsTimer. The former already resets
wakeUps; reset it in the latter as well.

2) waking up the dispatcher when we post an event from within an

with the core dispatcher, and passes 100% of the time with the GUI
dispatcher. On Linux, it passes only if a Glib based event dispatcher
is used; the default Unix event dispatcher (which is also the one
used on macOS for core applications) fails.

insert() behavior (what the STL calls insert_or_assign()), which
makes its insert() unusable for actual STL-style insert() work,
with no replacement except the size-check-and-index-operator trick:

    const auto oldSize = c.size();
    auto &e = c[key];
    if (c.size() != oldSize) {
        // inserted
    }

Even though QFlatMap::insert() appears to return the correct info,
it's useless, because the old value has been assigned over by the
time insert() returns.

We didn't delete the new'ed up QMetaTypeInterfaces, causing asan to
complain.

Fix by storing them in strong references alongside their users in a
statically-allocated container.

We use shared_ptr to hold them, because QMetaTypeInterface doesn't
have a virtual destructor, so deleting objects of the TypeInfo types
(plural!) derived from QMetaTypeInterface though a pointer to the base
class is UB. The shared_ptr constructor, however, is templated, so it
stores the correct call (~TypeInfo()) in its type-erased deleter.

We can't use std::make_shared(), because that doesn't support
aggregate initialization until C++20, so we manually new up the
TypeInfos.

5.15 is not affected.

11409f4c02 QStringBuilder: handle freeSpaceAtBegin() in op+=
Amends 9b320edb53.

The above commit made the mistake of relying on the 30yr+ old
fundamental relation

    size() - capacity() == freeSpaceAtEnd()

which, however, Qt 6's prepend()-optimization (freeSpaceAtBegin())
broke. Because of that, while size() - capacity() may be large enough
to hold the new data, if freeSpaceAtBegin() > 0, then freeSpaceAtEnd()
may not.

Fix by inspecting freeSpaceAtEnd() instead of capacity(). The
following reserve() call is unaffected, since it internally already
adds freeSpaceAtBegin() to the requested size, which is why the
unconditional reserve() in 9b320edb535a0fbe118933d2e983b73f90c32685^
worked while 9b320edb535a0fbe118933d2e983b73f90c32685's capacity()
check did not.

f8b74a4957 QXmlStreamReader: update test distribution
As mentioned in the linked bugreport, we are not allowed to distribute
the uncompressed files from one of the XML test datasets that we use
in our tests.
This patch removes the uncompressed version, and replaces it by the
xmltest.zip archive taken from [0].
Once the test is started, QZipReader is used to uncompress the archive,
and once the test is done, the uncompressed data is removed.

However the test data from [0] is very old, so it is slightly different
from what we had previously (the previous data was taken from w3c).
As a result, 4 test cases are failing with this data. To fix it, we
store the updated versions of 4 xml files separately, and replace them
after uncompressing the archive.

46dc8e453a QVariant: use a typedef name when saving user types to QDataStream
Due to the way Qt 5 and 6 registered type names, they end up producing
different type names for the same content for a typedef. For example,
because Q_DECLARE_METATYPE can't manage a comma (it's a macro), users
are forced to write something like:

 using MyTypeMap = QMap<QString, MyType>
 Q_DECLARE_METATYPE(MyTypeMap)

Qt 5's Q_DECLARE_METATYPE's argument "MyTypeMap" was the only name we
knew about the type, so that's what got saved in the stream. However, Qt
6 QtPrivate::typenameHelper is much more clever and obtains the name
from the compiler itself, so it "sees through" the typedef and registers
"QMap<QString,MyType>" as the official type name.

If another library/plugin has a different typedef name for the same type
(e.g., StringTypeMap), it's indeterminate which type gets saved and will
even change from run to run (depends on the QHash order).

[ChangeLog][QtCore][QDataStream] If QDataStream is used with a
QDataStream::Version < Qt_6_0 to serialize a user type that was
registered via a typedef with the metatype system, the typedef's name is
used in the stream instead of the non-typedef name. This restores
compatibility with Qt 5, allowing existing content to read the same
QDataStreams; reading from older Qt 6 versions should not be affected.
(Note: if more than one typedef name is registered, it's indetermine
which name gets used)

We do this because certain changes which change the bucket the

without warning. And recent and upcoming changes have changed
both this and erase(). We limit the search-space to
the minimum numBuckets * 4, where minimum numBuckets is current

e297e80fd0 QVarLengthArray: make reallocation strongly exception safe
The old code had several bugs:

- it immediately clobbered *this with new state, before having copied
  over the elements from the old to the new buffer

- when buffer relocation threw, it would keep the new (partially-filled)
  buffer and throw away the old

- it unconditionally used std::move() for non-relocatable types, making
  it impossible to restore the original buffer when a move throws

Instead of clobbering *this with new state, do all the work on the
side and change *this only once the reallocation has happened
successfully.

Also use q_uninitialized_relocate_n() and unique_ptr in the
implementation to simplify the code. The former got the necessary
update to use std::move_if_noexcept() instead of an unconditional
std::move() for the non-relocatable case.

[ChangeLog][QtCore][QVarLengthArray] The append()-like functions are
now strongly exception safe. This means reallocation will now use
copies instead of moves, unless the value_type has a noexcept move
constructor.

This commit extends functionality for QLocale::codeToLanguage()

The following ISO 639 codes are supported:
    * Part 1
    * Part 2 bibliographic
    * Part 2 terminological
    * Part 3

As a result of this change the codeToLanguage() overload without
the additional argument now returns a Language value if it matches
any know code. Previously a valid language was returned only if
the function argument matched the first code defined for that
language from the above list.

and languageToCode() that support specifying which ISO 639 codes

84fba93ebb QThread::create(): request interruption and join on destruction
If one destroys a running QThread, so far the behavior has been to crash
(à la std::thread) -- assuming the thread hasn't already signalled that
it has finished. This behavior is hostile to solutions such as using
QThread::create(), which always require a wait() before destroying the
thread object.

We can use the opportunity to change the behavior without breaking any
valid code. Instead of crashing, inside QThread's destructor we can ask
the new thread to quit, and then join it (à la std::jthread). This
simplifies the implementation of long-living runnables and the code that
manages them.

Deploying this solution for the whole QThread class may not be entirely
painless. While no correct code would work differently with the proposed
changes, incorrect code that deletes a running thread would no longer
crash "loudly" -- instead, it might deadlock "quietly", have memory
corruptions, etc.

Hence I'm limiting this approach to only the threads created by
QThread::create(), at least for the time being. This also side-steps
perhaps the biggest problem of generalizing the approach, which is that
placing such interrupt+join logic into~QThread's destructor would cause
it to be run _after_ a QThread subclass' own destructor has run,
destroying the subclass' data members too early. This might create
an antipattern if one chooses to subclass QThread. With create(), a
subclass in question exists, and it indeed has NSDMs, but it's entirely
under our control (in fact, I'm placing the logic just in its dtor).

[ChangeLog][QtCore][QThread] Destroying a QThread object created by
QThread::create() while the thread that it manages is still running will
now automatically ask that thread to quit, and will wait until the
thread has finished. Before, this resulted in a program crash. See the
documentation of QThread::~QThread() for more details.

In particular, it makes impossible passing lambdas that are capturing

54536bb5ae QString::arg: deprecate use of arbitrary Unicode digits as replacements
The only documented replacements for Q*String*::arg() are sequences like
%1, %2, %3 -- where the n-th number is expressed using a sequence of
ASCII digits [1].

The code parsing the replacements however used the QChar::digitValue()
function. That function simply checks if a QChar has a *Unicode digit
value* (no matter what its block/category is), and if so, returns the
corresponding digit value as an int (otherwise returns -1).

The result of this is that a sequence like "%¹" or "%१" actually
triggered substitutions (both count as "1"). Similarly, QChars with
a digit value would be parsed as part of longer sequences like "%1²"
(counting as "12" (!)).

This behavior is weird, undocumented, and extremely likely the usual
backstabbing by Unicode by using "convenience" QChar methods -- that is,
never *intended* by the implementation.

This commit deprecates (via warnings) such usages, which for the time
being are left working as before (in the name of backwards
compatibility). At the same time: given it's extremely unlikely that
someone would be deliberately relying on this behavior, it implements
the desired change of behavior (only accept sequences of ASCII digits)
starting from Qt 6.6, that is, after the next LTS.

Throughout Qt 6's lifetime users will still be able to control arg()'s
behavior by setting an env variable, but that variable (and the support
for Unicode digits) will disappear in Qt 7.

To summarize:

* Qt 6.3->6.5: default is Unicode digits, env var to control
* Qt 6.6->6.x: default is ASCII digits, env var to control
* Qt 7: only ASCII digits, no env var

[1] That's the name Unicode gives to them, cf. https://www.unicode.org/charts/PDF/U0000.pdf

[ChangeLog][QtCore][Deprecation Notices] The arg() functions
featured in Qt string classes have always been documented to require
replacements tokens to be sequences of ASCII digits (like %1, %2, %34,
and so on). A coding oversight made it accept sequences of arbitrary
characters with a Unicode digit value instead. For instance, "%2੩" is
interpreted as the 23rd substitution; and "%1²" is interpreted as the
12th substitution. This behavior is deprecated, and will result in
runtime warnings. Starting from Qt 6.6, arg()'s behavior will be changed
to accept only ASCII digits by default. That means that "%1²" is going
to be interpreted as substitution number 1 followed by the "²" character
(which does not get substituted, so it gets left as-is in the result).
Users can restore the previous semantics (accept Unicode digits) by
setting the QT_USE_UNICODE_DIGIT_VALUES_IN_STRING_ARG environment
variable to a non-zero value. In Qt 7, arg() will only support sequences
of ASCII digits. Note that from Qt 6.3 users can also set
QT_USE_UNICODE_DIGIT_VALUES_IN_STRING_ARG to zero; this will make arg()
use ASCII digits only, in preparation for the future change of defaults.

0e72a846d3 QObject: Q_ASSERT the object type before calling a PMF
The old-syle signal-slot syntax had the advantage of not delivering
signals to slots in derived classes after that derived class's
destructor had finished running (because we called via the virtual
qt_metacall). The new syntax made no checks, so a conversion from the
old to the new syntax may introduce crashes or other data corruptions at
runtime if the destructor had completed.

This commit introduces a Q_ASSERT to print the class name that the
object is not any more. Since this is in inline code, this should get
enabled for users' debug modes and does not therefore depend on Qt being
built in debug mode.

It required some Private classes to be adapted to the new form, by
exposing the public q_func() in the public: part.

8c9875893b Q(Multi)Map: prevent dangling key/value after detach()
Q(Multi)Map mutating functions that take reference to a key and/or a
value (e.g. insert(), take(), etc.) must make sure that those references
are still valid -- that is, that the referred objects are still alive --
after the detach() call done inside those functions.

In fact, if the key/value are references into *this, one must take extra
steps in order to preserve them across the detach().

Consider the scenario where one has two shallow copies of QMap, each
accessed by a different thread, and each thread calls a mutating
function on its copy, using a reference into the map (e.g.
map.take(map.firstKey())). Let's call the shared payload of this QMap
SP, with its refcount of 2; it's important to note that the argument
(call it A) passed to the mutating function belongs to SP.

Each thread may then find the reference count to be different than 1 and
therefore do a detach() from inside the mutating function. Then this
could happen:

Thread 1:                         Thread 2:

detach()                          detach()
  SP refcount != 1 => true          SP refcount != 1 => true
    deep copy from SP                 deep copy from SP
    ref() the new copy                ref() the new copy
  SP.deref() => 1 => don't dealloc SP
  set the new copy as payload
                                    SP.deref() => 0 => dealloc SP
                                    set the new copy as payload

  use A to access the new copy      use A to access the new copy

The order of ref()/deref() SP and the new copy in each thread doesn't
really matter here. What really matters is that SP has been destroyed
and that means A is a danging reference.

Fix this by keeping SP alive in the mutating functions before doing a
detach(). This can simply be realized by taking a local copy of the map
from within such functions.

remove() doesn't suffer from this because its implementation doesn't do
a bare detach() but something slightly smarter.

8926eb86c6 Fix formatting of dates before 1601 in MS system locale
The relevant MS system calls (say they) don't support date formatting
for years < 1601 (but apparently do in fact) and the year field of the
data structure is unsigned, so can't support years < 0. As a result,
the windows back-end for QSystemLocale failed for negative years.
So replace year < 1601 with a place-holder and substitute after
formatting.

Added new tests (based loosely on one in qtdeclarative that failed) to
verify that this actually works. These reveal that macOS also fails to
handle negative years; marked as expected failure there pending a fix.
