78b58d4de1 Tidy up tst_QLocale::ctor(), reduce needless repetition
The test macro's first three parameters were given a QLocale:: prefix
by the macro, but the last three weren't. Save uses of the macro the
need to repeat the prefix in all parameters, thereby making the test
cases easier to read. Also, we can compare enum values, rather than
casting them to int; and, when a test fails, reporting the enum name
is far more informative than reporting the integer that represents it.

d4b206b246 Split QMutex and QRecursiveMutex
These classes should not inherit from each other
anymore in Qt 6. The reason is that this makes
the 95% case of using a non-recursive mutex
much slower than it has to be.

This way, QMutex can now inline the fast path
and be pretty much as fast as QBasicMutex is
in Qt 5. They actually use the same code paths
now. The main difference is that QMutex allows
calling tryLock() with a timeout, which that
is not allowed for QBasicMutex.

[ChangeLog][QtCore][QMutex] QMutex does not support
recursive locking anymore. Use QRecursiveMutex for that
purpose. QRecursiveMutex does not inherit QMutex anymore
in Qt 6.

fa93f1aeb0 Fix compile time type normalization code
Use a simpler constexpr to generate type name on gcc This
works around an ICE on gcc in release mode when compiling
with PCH enabled. As the type we're getting from Q_FUNC_INFO is
already in a somewhat normalized form, this requires significanlty
less processing and esp. not a recursive constexpr method which
I suspect triggers the ICE.

Fix integer type conversions to also properly normalize long long
values (to q(u)longlong. Make sure the mapping also works on
MSVC, where long long types get mapped to __int64. Also, normalize
unsigned short and unsigned char to ushort and uchar, respectively, to
follow the convention set by uint and ulong.

Add some test cases to verify the mappings.

b83225fcc3 qDebug: Avoid implicit QVariant conversion
This commit restricts operator<<(QDebug lhs, QVariant rhs) to only work
if rhs is actually of type QVariant (instead of any type convertible to
QVariant). This is especially important as
a) we check in QMetaType whether (slightly simplified) QDebug{} <<
   std::declval<T>() is valid, and if so, register a function which
   simply uses the operator.
b) In QVariant, we ask the metatype system for the contained types
   registered debug function and then use it.
If a type now does not have its own operator<< for QDebug, but is
implicitly convertible to QVariant containing itself, this would lead to
an infinite recursion, when trying to use qDebug with that type. The
registered function in a) would just convert the type to QVariant, and
then ask the QVariant to print itself.
Disallowing implicit conversions in qDebug in general was considered
(i.e. adding template<typename T> operator<<(T) = delete in QDebug ),
but discarded as it breaks too much code relying on conversions.

cb0ecd6b6d Check value is in range when setting a QDateTime
Previously, a QDate representing more than about 0.3 gigayears before
or after the epoch would overflow the millisecond count and produce a
"valid" date-time that didn't represent the date and time passed to
its constructor.  Changed to detect such overflow and produce an
invalid date-time instead, if it happens.

Corrected some tests that wrongly expected to be able to represent
extreme date-time values with every time-spec.  The (milli)seconds
since epoch are from UTC's epoch, so converting to another offset,
zone or local time may give a value outside the actual range.  Added
some tests for the actual exact bounds.

e5dc46d966 Allow millisecond-overflow when the result remains valid
Even before adding support for fractional hours, a fraction of a
minute might potentially have represented a whole number of seconds by
a fractional part that, due to rounding, was less than the whole
number of seconds by less than half a millisecond. Previously, the
parsing would have clipped the fractional part at 999 milliseconds, in
the preceding second, instead of correctly rounding it up to the whole
second.

For QTime::fromString(), which can't represent 24:00, and for
TextDate, which doesn't allow 24:00 as a synomym for the next day's
0:0, applying such rounding to 23:59:59.999999 would produce an
invalid result from a string that does represent a valid time, so use
the nearest representable time, as previously.

Added some tests and amended others.

[ChangeLog][QtCore][QDateTime] QDateTime and QTime, in fromString()
with format ISODate or TextDate, now allow a fractional part of the
hour, minute or seconds to round up to the next second (hence
potentially into the next minute, etc.) when this is the closest
representable value to the exact fractional part given. When rounding
up would turn a valid result into an invalid one, however, the old
behavior of clipping to 999 milliseconds is retained.

QUrl hostnames must be compliant with STD3, but we must somehow accept

valid but local file path. If given to QUrl::fromLocalFile(), if the
path at the root does parse as a hostname, we will still try to
normalize (the above becomes "file://x/y").

4e675cb85e Handle trailing cruft consistently in Qt::DateFormat parsing
Previously the ISO time format would tolerate trailing cruft at the
end in various cases even though there might be an offset specifier
after the time, which should *not* be separated from it by anything
(not even the spaces we originally planned to still tolerate).

The RFC date format is forgiving about space, as is suitable for
parsing of RFC-822 headers, but the other formats should match the
handling in QDateTimeParser, which rejects any dangling cruft.

At the same time, since this required a re-write of
fromIsoTimeString() in any case, add support for the ISO format that
gives the hour a fractional part and skips minutes and
seconds. Previously we only had support for fractional minutes (with
no seconds). The hour without even a fractional part is also valid.

Reworked the documentation of Qt::DateFormat as it was wrong in
places, inconsistent in its formatting and incomplete. Adjusted some
tests to match the new behavior. A fraction separator with no
following digits should have been recognized as an error previously
and now is.

[ChangeLog][QtCore][QDateTime] The ISODate and ISODateWithMs formats
now reject trailing cruft (including spaces) at the end of a time
string. They also gain support for parsing hour-only formats,
including the hour-with-fractional-part format.

Address an old ### Qt 5 comment. The method has been documented as deprecated

properly flag it as such for 5.15.2, and remove it from Qt 6 in a follow-up

1c591fd924 Deal with {und,ov}erflow issues in QLine's length handling
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.

8572f84467 Fix ChangeHandler notification for eager properties
ChangeHandler's evaluated the binding to detect if the value actually
changed. This is a valid strategy for lazy bindings, but eager bindings
were already evaluated at that point, and thus the change would not be
detected.
Change the binding loop test, so that there isn't a fixpoint in the
binding loop, and we can still detect it. Changing the binding loop
detection code to deal with this case is left as an exercise for the
future.

6892300127 QVariant: Change metatype in convert() even on failure
The documentation of convert promised that “If the cast cannot be
done, the variant is still changed to the requested type”. This was not
the case so far, because we returned too early if canConvert returned
false.
This commit changes the behavior of the method to reflect its
documentation. The documented behavior seems more useful than the
alternative of not changing the metaType, at least for common use cases
inside qtdeclarative.
