cf7d990a48 Fix reference to a dead temporary
NoDefaultConstructorRef1 was taking a reference of the input, which
meant in the first test it would get a reference to the temporary
created by the 1 literal. A temporary that would be out of scope by
the time we check its value.

Instead add a test with unique_ptr to test we can pass movable
temporaries.

b9f96cacc9 QRegExp: remove an out of bounds access into QString
... 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.

9dfc2aa75d Purge use of some deprecated methods from QDateTime tests
QDateTime's short names setUtcOffset() and utcOffset() have been
deprecated since 5.2, in favor of setOffsetFromUtc() and
offsetFromUtc().

QDate's shortDayName() and shortMOnthName() have been deprecated since
5.10, in favor of QLocale's dayName() and monthName().  Also, the
tests that were using them are testing methods only present when the
datestring feature is enabled; so condition them on that feature.

82ad4be4a2 Fix various uncommon cases in QTzTimeZonePrivate backend
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).

954b73445c Refine underflow check in QLocaleData::convertDoubleToFloat()
A string can parse as a non-zero double that's smaller than the
smallest float yet be a faithful representation of the smallest float.
So rather than testing for non-zero doubles less than the smallest
float, test for non-zero doubles that cast to float zero; these
underflow.  This means small values close below the smallest float
shall round up to it, rather than down to zero, requiring a tweak to
an existing test.  Added a test for the boundary case (and tidied the
test data).

While an invalid time-zone shall have no transitions, so may various
constant zones, like UTC.  The TZ data may include only the POSIX rule
for such a zone, in which case we should use it, even if there are no
transitions.

Broke out a piece of repeated code as a common method, in the process,
since I was complicating it further.

Added test for the case that revealed this; and made sure we see a
warning if any of the checkOffset() tests gets skipped because its
zone is unsupported.

c066656aff Avoid read-outside-array error by QStringRef over-reach
Constructing a QStringRef directly from the string, offset and a
length is UB if the offset + length exceeds the string's length.
Thanks to Robert Loehning and libFuzzer for finding this.
QString::midRef (as correctly used in both changed uses of QStringRef,
since 432d3b6962) takes care of that for us.  Changed one UB case and
a matching but correct case, for consistency.

In the process, deduplicate a QStringList look-up.
Added tests to exercise the code (but the one that exercises the
formerly UB case doesn't crash before the fix, so isn't very useful;
the invalid read is only outside the array it's scanning, not outside
allocated memory).

76dfda1ad1 Use RAII to handle setting of default locale in tst_QString
Various tests were setting the default locale and relying on cleanup()
to "restore" the C locale; which needn't actually be the locale we
started out in and, in any case, was the wrong locale for some tests.
So handle this via an RAII class that records the actual prior locale
and restores it on destruction.

ab448f731e Handle QCollator with locale C by delegating to QString
Previously, the C locale was treated as English because each back-end
takes the locale's bcp47Name(), which maps C to en. However, the C
locale has its own rules; which QString helpfully implements; so we
can delegate to it in this case. Extended this to sort keys, where
possible. Clean up existing implementations in the process.

Extended tst_QCollator::compare() with some cases to check this. That
required wrapping the test's calls to collator.compare() in a sign
canonicalizer, since it can return any -ve for < or +ve for >, not
just -1 and +1 for these cases (and it'd be rash to hard-code specific
negative and positive values, as they may vary between backends).

[ChangeLog][QtCore][QCollator] Added support for collation in the C
locale, albeit this is only well-defined for ASCII. Collation sort
keys remain unsupported on Darwin.

ce159d1a3e Fix toFloat()s between float and double ranges and document
Revised some toFloat()s to be consistent with the matching
toDouble()s; previously, they would return infinity if toDouble() did
but return 0 if toDouble() got a finite value outside float's range.
That also applied to values that underflowed float's range, succeeding
and returning 0 as long as they were within double's range but failing
if toDouble() underflowed.  Now float-underflow also fails.  Amended
their documentation to reflect this more consistent reality.
Added some tests of out-of-range values, infinities and NaNs.

[ChangeLog][QtCore][toFloat] QString, QByteArray and QLocale returned
an infinity on double-overflow (since 5.7) but returned 0 on a finite
double outside float's range, while setting ok to false; this was at
odds with their documented behavior of returning 0 on any failure.
They also succeeded, returning zero, on underflow of float's range,
unless double underflowed, where they failed.  Changed the handling of
values outside float's range to match that of values outside double's
range: fail, returning an infinity on overflow or zero on underflow.
The documentation now reflects the revised behavior, which matches
toDouble().

e00c73911a Reduce run time of tst_QRegularExpression::threadSafety
This test was taking so much time that it regularly timed out on WinRT
and when running in qemu. Reduce it from around 40 to 7 seconds on a
powerful desktop.
Now it either runs for two full seconds for each test function or until
it has done 50 iterations.

Fixes: QTBUG-71405

fc88dd52a4 QByteArrayList: add indexOf(const char*) overload
This avoids memory allocation and data copying in e.g.
QObject::property().

Detected by heaptrack's "Temporary allocations" counter in an
application using the breeze widget style (many animations).

7e7514482f winrt: Skip a test row of tst_QRegularExpression::threadSafety
PCRE2 does not support JIT on winrt. This test row takes a long time
(30 seconds here) without JIT and thus might cause test timeouts in
COIN when run on winrt.

6c543879a3 Avoid races on TZ in environment via tzset() calls
POSIX specifies that tzset() consults environment variable TZ and
modifies some globals; it also specifies mktime(), localtime() and
strftime() to behave as if they called tzset().  Fortunately, we only
call strftime() from a test and only call localtime() when not
threaded.  Provide wrappers for tzset() and mktime() that share the
lock used by our environment-access code, to prevent races on the
environment (and tzset()'s globals) when we call them.

In the process, re-use tst_QDateTime's TimeZoneRollback in its older
test systemTimeZoneChange() and presume that this can now be tested
cross-platform, since TimeZoneRollback is used in another test where
this works.
