8c2969ea86 QPlugin: Move the plugin metadata to a note in ELF platforms
A few systems, like OpenWRT, may strip the section table off the
resulting binaries (see [1]), making it impossible for us to pinpoint
the exact location of the Qt plugin metadata. This commit moves the meta
data to a location that is identifiable even in fully stripped binaries:
an ELF note.

By naming our section ".note.qt.metadata", we instruct the linker to
place it along the other notes and to mark it in the program header
section. Another advantage is that the notes are usually in the very
beginning of the file, as they are used by the dynamic linker itself, so
we'll need to read much less of the full contents.

The unit test is modified not to attempt to strip the plugin of
debugging data. In fact, we add something to the end that would,
otherwise, be matched as (invalid) metadata.

The following was produced with GCC 11 and GNU binutils ld 2.36.1.

Section Headers:
[Nr] Name                 Type         Addr             Off      Size     ES Flags Lk Inf Al

Program Headers:

...
  NOTE           0x0002a8 0x00000000000002a8 0x00000000000002a8 0x000030 0x000030 R   0x8

The Qt metadata note is 4-byte aligned and can thus be found in the
second note section, which spans from 0x02d8 to 0x02d8+0xac=0x0384.

GNU readelf -n can even show it:

Displaying notes found in: .note.qt.metadata
  Owner                Data size        Description
  qt-project!          0x0000018f       Unknown note type: (0x74510001)
   description data: 01 06 03 81 bf ...... ff

I chose 0x7451 as the prefix for our notes, even though they're already
namespaced by the owner in the first place, because eu-readelf
mistakenly tries to interpret note 1 as a GNU ABI tag regardless of
owner. The owner name was chosen to be 12 bytes long, so the ELF note
header is 24 bytes in total. There's no space wasted because the payload
needs to be aligned to 32-bit anyway and I didn't want to use only 4
characters (header total size 16 bytes) so we'd skip the "GNU" note on
size, without string comparison. And I couldn't think of a 4-character
representative string ("QtP" ?).

cb0ea39895 CMake: remove support for building Qt with the old Intel compiler
This hasn't worked for some time. It's not in our CI and I don't think
it was working at all. When I tried to build it, I ran into several
problems with C++17 and an Internal Compiler Error I did not have any
interest in working around.

After discussing with the Intel compiler team, it was decided that
fixing those issues in the old compiler is not going to happen. Instead,
their recommendation is to adopt the new LLVM-based compiler, which
the last commit added support for.

This commit does not remove qmake support for the old ICC. It's possible
someone is using qmake with a non-Qt6 project and ICC.

ba23507960 Fix handling of time-zone gap in QTimeZonePrivate::dataForLocalTime()
This was handled correctly when the backend supplies transitions
bracketing the time in question, but the fallback code tried to use
the DST offset at the time with larger offset from UTC; this did not
work when the gap was due to a change in standard time. Discovered by
ANS1 parsing of a date-time with two-digit year, for which the
date-time parser tried to use 1921-05-01T00:00 local time when filling
in the fields it had parsed; but, when run in Europe/Helsinki, there
is no such time due to the 20m 11s skipped when joining EET from the
prior local solar mean time.

Correct the calculation to use the actual change in offset from UTC,
as used in the (far better tested) between-transitions branch of the
code, rather than the DST offset after the transition.

Add a test-case based on the ASN.1 certificate date whose parsing
revealed the issue. Although it seems nothing in Coin can reproduce
the issue, the reporter has verified that the test does indeed fail on
the system where the bug was found and the fix does fix it.

878b2047b5 QList::iterator: use templates for advancing operators
Because of the addition of the operator T*(), the expression "it + N"
where N was not exactly qsizetype but any other integer type was a
compilation failure because of ambiguous overload resolution.

With GCC it's apparently a warning:

 warning: ISO C++ says that these are ambiguous, even though the worst conversion for the first is better than the worst conversion for the second:
 note: candidate 1: ‘QList<T>::iterator QList<T>::iterator::operator+(qsizetype) const [with T = char; qsizetype = long long int]’
 note: candidate 2: ‘operator+(char*, ptrdiff_t {aka long int})’ (built-in)

With Clang, it's an error:

 error: use of overloaded operator '+' is ambiguous (with operand types 'QList<int>::const_iterator' and 'ptrdiff_t' (aka 'long'))
 note: candidate function
        inline const_iterator operator+(qsizetype j) const { return const_iterator(i+j); }

46fc01d7ca QElfParser: rewrite using elf.h
This rewrite uses the actual structures supplied by the system's C
library, so it should be easier to read. It removes hardcoded constants
with little evident meaning in favor of sizeof() and the macros from
that header. It also removes advancing the data pointer in favor of
having absolute offsets.

The resulting implementation is stricter than the original, checking
more fields in the header. Because the QPluginLoader and QFactoryLoader
users may make decisions based on availability of plugins before
attempting to load them, it's better to be stricter here than to fail
later when trying to dlopen() them.

Debugging and testing are much improved. Instead of stored artifacts, I
added a routine to modify a valid plugin to make it invalid, given the
conditions we've found so far.

If you turn debugging on for this category, you'll see things like:

2c3617dfcb Always enable QRegularExpression's JIT when testing
Given on most CI configurations we run tests only on debug builds, this
means that effectively we don't test JIT paths (JIT is kept disabled in
debug builds). To keep it enabled in a test, we have a few options:

* export a developer-build-only variable from QtCore, to force JIT
usage, and set it in the test. This is still suboptimal as many
configurations aren't using developer builds in the first place;

* use the already existing QT_REGEXP_USE_JIT environment variable,
setting it from CMake/CTest. The problem here is that although add_test
does support it, we don't expose it through our wrapper functions;

* just set that env variable from within the test itself. I went for
this option.

461084b6c4 Q{Elf,Mach}Parser: harmonize the arguments passed
Both functions took a QString for the input file name, but while the ELF
parser had an optional QLibrary pointer (which was never null) where to
store the error string, the Mach-O parser received a pointer to a
QString. So make both of them take a single in/out QString pointer,
which has the file name on input and is cheap for us because of COW.

Drive-by fix the name of the static function in qmachparser.cpp from
"ns" (which stood for "not suitable") to "notfound".

With the QRegExp variant removed, it was weird to have all QSFPM
tests in "tst_qsortfilterproxymodel_regularexpression", even those
completely unrelated to regexps. Instead of reuniting into a single
executable as before, I simply split it out in separate executables:

* tst_qsortfilterproxymodel has the "standard" QSFPM tests
* tst_qsortfilterproxymodel_regularexpression has the regexp-related tests
* tst_qsortfilterproxymodel_recursive is separate as before

57960ab075 Q{Elf,Mach}Parser: simplify the return codes
The multi-state return code was a legacy of how Arvid wrote the ELF
parser code back in the day, the fact that it scanned for two different
types of plugins in Qt 4 and that the metadata could exist in different
places.  None of that matters nowadays: who cares if the file is a
corrupt binary, not a valid binary, does not have the right
architecture, or has no suitable section? It's not a plugin, period.

The Qt 4 plugin mechanism was removed for Qt 5.0 in commit
7443895857 ("Remove support for Qt 4 style
plugins").

458d53f572 Move locale-switching code in tests to a shared header
QLocale and QString tests had copies of a TransientLocale; we've
recently improved the QLocale one. Rather than duplicating those
rather complicated improvements, finally share a common version.

In the process, I noticed that setlocale() only returns the prior
value when passed nullptr as the new value; so rework the
implementation to get that right, so that it now correctly restores
the prior locale. That, in turn, means there's now a later call to
setlocale(), when we actually set the changed setting, which may
invalidate the earlier return; so copy it to a QByteArray before the
second call.

Included Ivan Solovev's improved version of how to reset the locale,
since TransientLocale needs it.

QLatin1String) they are handled as UTF-8. This renames the check to
is_bytearray_like_v and clarifies its usage. No need to handle

4641ff0f6a Add new am/pm format-specifier that preserves locale's case
The existing a, ap, A and AP specifiers all force the case of the
formatted am/pm indicator. The indicators returned by QLocale's
amText() and pmText() methods are those given in CLDR, with no case
coercion. Application writers may reasonably want these strings used
verbatim, rather than having to chose a case and impose it on the
locale's indicators, in defiance of national custom. For example,
while en_US uses upper-case indicators by default, cs_CZ uses
lower-case ones. An application author writing a time format has been
forced to chose which of these locales to be wrong in.

Add support for aP and Ap specifiers, whose mixed case indicates that
the locale's case is to be respected. Amend an existing test-case of
tst_QLocale's formatDateTime() that used Ap (expecting, of course, an
upper-case indicator followed by a stray p) to now expect the
locale-appropriate-cased indicator. Extend formatTime() to test cases
using aP and Ap, to illustrate the difference between en_US and cs_CZ.

Rework QDateTimeParser to also support the new format specifier. This
required expanding its Case enum, used by the getAmPmText() method,
which was formerly shared with QDateTimeEditPrivate; however, as that
class no longer makes any reference to this method, it and the enum
can be made private, allowing a systematic clean-up of their use.
Added test-cases for both serialization and parsing; and amended some
existing parsing tests to verify am/pm indicators are matched
case-insensitively.

[ChangeLog][QtCore][Important Behavior Changes] Time formats used by
QLocale, QTime and QDateTime's parsing and serialization now recognize
'aP' and 'Ap' format specifiers to obtain an AM/PM indicator, using
the locale-appropriate case for the indicator, where previously the
author of a time format had to pick a case that might conflict with
the user's locale. For QTime and QDateTime the locale is always C,
whose indicators are uppercase. For QLocale, the case will now match
that of amText() or pmText(). Previously, 'aP' would have been read as
a lower-case indicator followed by a 'P' and 'Ap' as an upper-case
indicator followed by a 'p'. The 'P' or 'p' will now be treated as
part of the format specifier: if the prior behavior is desired, either
use 'APp' or 'apP' as format specifier or quote the 'p' or 'P' in the
format. The prior 'a', 'ap', 'A' and 'AP' specifiers are otherwise
unaffected.

9f13842fe6 Fix compilation for recursive Qt containers
The operator checks cause compilation errors when trying to check for
their existence for recursive containers. This happens because of trying
to check for the operators on the template parameter type(s), that
inherit from the container itself, which leads to compilation errors.
Introduced alternative versions of the operator checks (with _container
suffix), that first check if the container is recursive, i.e. any of its
template parameter types inherits from the given container, and skips
the operator check, if that's the case.

The fix is done for all Qt container types that had the problem, except
for QVarLengthArray and QContiguousCache, which don't compile with
recursive parameter types for unrelated reasons.

We have previously been using the standalong (nominative) month names
both when asked for that and when asked for the plain (genitive) month
name, probably because there was no LCTYPE value for the
latter. However, MS's docs for the standalone values do contain a
comment telling us how to get the genitive names.

Rename the old monthName() to standaloneMonthName() and add a
monthName() that calls GetDateFormat() suitably, as described by the
MS doc.

f0c2c987e3 QBA(V)/QS(V)::lastIndexOf: fix the search of 1-char needles
When a needle has length 1 (because it's a QChar/char16_t, or because
it's a string-like of length 1) then an ad-hoc search algorithm is
used. This algorithm had a off-by-one, by not allowing to match at
the last position of a haystack (in case `from` was `haystack.size()`).

That is inconsistent with the general search of substring needles
(and what QByteArray does). Fix that case and amend wrong tests.
This in turn unveiled the fact that the algorithm was unable to cope
with 0-length haystacks (whops), so fix that as well. Drive-by, add a

70df6052d8 tst_QPluginLoader: Simplify creating a fake pointer in fakeplugin.cpp
When assigning multiple variables to a specific section, both GCC
and Clang legitimately error out if those variables wouldn't end
up in the same section (e.g. if one of them is going to a read-only
section while the other one is going to a read-write section).

In C++, when a seemingly const variable needs dynamic initialization,
it needs to be stored in a read-write section.

Clang 13 changed internals for how some constants are materialized.
Now, when a variable is initialized with an expression containing
plain old fashioned casts, it is considered to be potentially
runtime initialized (at the point when section assignment conflicts
is evaluated). Therefore, Clang 13 errors out on fakeplugin.cpp
with errors like:

    fakeplugin.cpp:36:39: error: 'message' causes a section type conflict with 'pluginSection'
    QT_PLUGIN_METADATA_SECTION const char message[] = "QTMETADATA";
                                          ^
    fakeplugin.cpp:32:40: note: declared here
    QT_PLUGIN_METADATA_SECTION void *const pluginSection = (void*)(0xc0ffeec0ffeeL);
                                           ^

See https://bugs.llvm.org/show_bug.cgi?id=51442 for discussion
on the matter in Clang.

To simplify things, just initialize the fake pointers as regular
uintptr_t instead, avoiding the whole matter. This produces the
exact same contents in the section as before.

For what it's worth, the actual manually constructed metadata in
fakeplugin.cpp doesn't seem to have any effect on running the
QPluginLoader tests on either ELF or MachO right now.

11d1dcc6e2 QString: use the QRegularExpression operations on QStringView
There's no need of duplicating code all over the place; QString can
reuse the implementation of the indexOf/contains/count/lastIndexOf
family of functions already existing for QStringView.

For simplicity, the warning messages (that our autotests actually check)
have been made more generic, rather than introducing some other
parameter (as in, "which class is using this functionality so to emit
a more precise warning"), which would have just complicated things as
the implementation of these functions is exported and used by inline
QStringView member functions.

f0d1f50e02 QRegularExpression: fix matching over null/empty QString(View)
An empty QString(View) is allowed to have nullptr as its data pointer
(of course, only if its size is 0). This wasn't properly
checked in QRegularExpression, which passed such nullptr to
PCRE, and that resulted in PCRE raising an error (PCRE_ERROR_NULL).
Detect this case and pass a dummy pointer to keep PCRE happy.

Fixing and testing this in turn exposed a problem with QStringView
support in QRegularExpression when used over a null QString: the
code is supposed to use the QStringView(QString) constructor and NOT
qToStringViewIgnoringNull. That's because QRE distinguishes null
and empty subjects; when using qToStringViewIgnoringNull over
a null QString, one gets a non-null QStringView (!). Again, this in
turn exposed a problem with a QRegularExpression autotest that assumed
that a null match could only mean "no match" (instead, it can happen at
position 0 of a null QString(View)).

6cee204d56 QS(V)/QBA(V)/QL1S::lastIndexOf: fix the offset calculations
When trying to fix 0-length matches at the end of a QString,
be83ff65c4 actually introduced a
regression due to how lastIndexOf interprets its `from` parameter.

The "established" (=legacy) interpretation of a negative `from` is that
it is supposed to indicate that we want the last match at offset `from +
size()`. With the default from of -1, that means we want a match
starting at most at position `size() - 1` inclusive, i.e. *at* the last
position in the string. The aforementioned commit changed that, by
allowing a match at position `size()` instead, and this behavioral
change broke code.

The problem the commit tried to fix was that empty matches *are* allowed
to happen at position size(): the last match of regexp // inside the
string "test" is indeed at position 4 (the regexp matches 5 times).

Changing the meaning of negative from to include that last position (in
general: to include position `from+size()+1` as the last valid matching
position, in case of a negative `from`) has unfortunately broken client
code. Therefore, we need to revert it. This patch does that, adapting
the tests as necessary (drive-by: a broken #undef is removed).

Reverting the patch however is not sufficient. What we are facing here
is an historical API mistake that forces the default `from` (-1) to
*skip* the truly last possible match; the mistake is that thre is simply
no way to pass a negative `from` and obtain that match. This means that
the revert will now cause code like this:

  str.lastIndexOf(QRE("")); // `from` defaulted to -1

NOT to return str.size(), which is counter-intuitive and wrong. Other
APIs expose this inconsistency: for instance, using
QRegularExpressionIterator would actually yield a last match at position
str.size(). Similarly, using QString::count would return `str.size()+1`.
Note that, in general, it's still possible for clients to call

  str.lastIndexOf(~~~, str.size())

to get the "truly last" match.

This patch also tries to fix this case ("have our cake and eat it").

First and foremost, a couple of bugs in QByteArray and QString code are
fixed (when dealing with 0-length needles).

Second, a lastIndexOf overload is added. One overload is the "legacy"
one, that will honor the pre-existing semantics of negative `from`. The
new overload does NOT take a `from` parameter at all, and will actually
match from the truly end (by simply calling `lastIndexOf(~~~, size())`
internally).

These overloads are offered for all the existing lastIndexOf()
overloads, not only the ones taking QRE.

This means that code simply using `lastIndexOf` without any `from`
parameter get the "correct" behavior for 0-length matches, and code that
specifies one gets the legacy behavior. Matches of length > 0 are not
affected anyways, as they can't match at position size().

[ChangeLog][Important Behavior Changes] A regression in the behavior of
the lastIndexOf() function on text-related containers and views
(QString, QStringView, QByteArray, QByteArrayView, QLatin1String) has
been fixed, and the behavior made consistent and more in line with
user expectations. When lastIndexOf() is invoked with a negative `from`
position, the last match has now to start at the last character in the
container/view (before, it was at the position *past* the last
character). This makes a difference when using lastIndexOf() with a
needle that has 0 length (for instance an empty string, a regular
expression that can match 0 characters, and so on); any other case is
unaffected. To retrieve the "truly last" match, one can pass a
positive `from` offset to lastIndexOf() (basically, pass `size()` as the
`from` parameter). To make calls such as `text.lastIndexOf(~~~);`, that
do not pass any `from` parameter, behave properly, a new lastIndexOf()
overload has been added to all the text containers/views. This overload
does not take a `from` parameter at all, and will search starting from
one character past the end of the text, therefore returning a correct
result when used with needles that may yield 0-length matches. Client
code may need to be recompiled in order to use this new overload.
Conversely, client code that needs to skip the "truly last" match now
needs to pass -1 as the `from` parameter instead of relying on the
default.

d055abd195 Assert that special handling of '0' padding does what it should
When formatting numbers, if the fill character used to left-pad to
field widths is '0', the code delegates that padding to the
QLocaleData's ZeroPadded formatting option. Since we want the zeros
before any minus sign, and don't want to subsequently add more zeros
before it, check that this has worked as expected when calling
replaceArgEscapes(), to confirm that it doesn't need to worry about
that.

bef57b317f testlib: Deprecate QWARN() in favor of qWarning()
The QtTest best practices documentations recommends using output
mechanisms such as qDebug() and qWarning() for diagnostic messages,
and this is also what most of our own tests do.

The QWARN() macro and corresponding internal QTest::qWarn() function
was added when QtTest was first implemented, but was likely meant as
an internal implementation detail, like its cousin QTestLog::info(),
which does not have any corresponding macro.

This theory is backed by our own QtTest self-test (tst_silent)
describing the output from QWARN() as "an internal testlib warning".

The only difference between QWARN() and qWarning(), besides the much
richer feature set of the latter, is that qWarning() will not pass
on file and line number information in release mode, but QWARN() will.
This is an acceptable loss of functionality, considering that the user
can override this behavior by defining QT_MESSAGELOGCONTEXT.

[ChangeLog][QtTest] QWARN() has been deprecated in favor of qWarning()

e150bcfe4d QByteArray: fix indexOf/lastIndexOf
This patch fixed two bugs in indexOf/lastIndexOf:
1. The lastIndexOf(char, qsizetype) overload was crashing with an empty
   QByteArray. It was unconditionally calling lastIndexOfCharHelper()
   which assumes that this QBA is not empty. An explicit check for
   the empty case is added.
2. The indexOf(QByteArray, qsizetype) overload was behaving incorrectly
   while searching for an empty QByteArray. In this case it
   unconditionally returned its second parameter (from). However, from
   can be negative, or even exceed the size of this QByteArray. This
   patch handles this cases properly.

As a drive-by: this patch adjusts the QByteArray::indexOf(char, qsizetype)
and QByteArray::lastIndexOf(char, qsizetype) overloads to match with the
QByteArrayView implementation. This is done to have similar code paths
in both cases and avoid tricky bugs in future.
Ideally we had to adjust the QByteArrayView implementation, but it's
fully inline, so can't be changed without breaking BC.

C++20 deprecated compound volatile statements such as pre- and

you're now supposed to write

    int j = i; // volatile load
    ++j;
    i = j; // volatile store

which matches more closely what hardware does.

fashion individually, and realising that probably a few more Qt
modules will have the same kind of code patterns in them, write

Add a new function, nextFileInfo(), with returns fileInfo() instead.
Incidentally, the returned object has already been constructed as part
of advance()ing the iterator, so the new function is faster than
next() even if the result is ignored, because we're not calculating a
QString result the caller may not be interested in.

Use the new function around the code.

This was leading to a confusing situation when calling squeeze() on

unneeded memory, not to allocate more.

This patch adds a check for non-zero capacity. As a result, nothing

In case of trying to report results via an empty list, the size is 0, so
result store treats it as a single result.

Added checks before storing the results to make sure that the result
list isn't empty. Note that empty lists are allowed in some cases for

7b1b1d990b QFileSelector: Preserve path to root directory
While QFileSelector is documented to work on files, select accepts
arbitrary URLs. Moreover, the QML engine can end up intercepting
arbitrary (user provided) URLs, including to directories.
Prior to this change, passing "file:///" or "/" to the function would
break: We would temporarily get a "//" path, which is invalid, and thus
we would return an invalid in the end.

In QItemSelectionModel, items which are disabled or marked as not
selectable should not be considered as selected. But this was
not handled consistently.
The following methods considered only items which are enabled and
marked selectable: selectedIndexes(), rowIntersectsSelection(), and
columnIntersectsSelection(). The following methods considered only
items which are marked selectable, but did not check whether they
are enabled: selectedRows(), selectedColumns(), isRowSelected(),
isColumnSelected(), isSelected(). Finally there is hasSelection(),
which did not check for enabled nor for selectable.
This patch introduces consistent behavior. All methods check
both whether the items are enabled and whether they are selectable now.

27d6314b95 QCryptographicHash: use a std::array to hold result (was: QByteArray)
The maximum size for a hash result is 64 atm. Even if, and esp when,
we'll get to 128 and 256 bytes in the future, there's no reason to use
dynamic memory, because the sizes will always be statically known.

So use, essentially, a std::array<char, 64> to hold the result
internally. Add a bit of convenience API on top to limit impact on the
rest of the code and add a few static_asserts that ensure this is large
enough. Then give users access to the internal buffer by adding
QByteArrayView resultView() const noexcept. The documentation snippet
is taken from QString::data(), suitably adjusted.

Use resultView() in a few places instead of result().

[ChangeLog][QtCore][QCryptographicHash] Changed to use a
statically-sized buffer internally. Added resultView() to access it.

    ^
By using SFINAE for the TypeInfo we can also ensure that it works for
types that are not native interfaces, such as if the user tries to
call nativeInterface<QString>().

Since we can no longer use decltype(*this) to resolve the base type
we need to change QT_DECLARE_NATIVE_INTERFACE_ACCESSOR to take the

2b50c8bec0 QObject: optimize the common case of findChildren(QString())
Outside tests, all in-tree callers of QObject::findChildren() pass no
name to match, and in my experience that is also true for the vast
majority of out-of-tree users.

Avoid the temporary QString creation in the caller and the repeated
QString::isNull() checks in the implementation by overloading
findChildren() without a name argument and checking for name.isNull()
only once, forking off into separate helper functions.

Adjust in-tree callers that used an explicit `QString()` argument in
order to pass options, which goes to show that `name` should never
have been the first argument of findChilden() in the first place, even
though I appreciate the symmetry with findChild() (the use-cases of
which, however, are radically different).

Change a `findChildren().size() == 0` call found while scanning for
findChildren() calls to `!findChild()` as a drive-by.

Modernize loops in the various qt_qFindChild{,ren}_helper() overloads
to match how the new code looks.

[ChangeLog][QtCore][QObject] Added findChildren() overload taking no
name (thus optimizing this common case).

3eac6079d9 macOS: Don't mangle QByteArray settings with @ prefix by decoding as UTF-8
QSettings encodes QVariants as @Type(data) strings. If that data contains
a null-byte, we write the string as UTF-8 encoded CFData. When reading it
back we look for a @ prefix, and then pass it as UTF-8 through stringToVariant.

The problem arises then the user writes raw QByteArrays with a @ prefix.
We can detect this situation by checking the result of stringToVariant,
and if it's just a simple conversion of the string into a QVariant, we
know that stringToVariant hit its fallback path due to not finding any
embedded variants.

If that's the case, we return the raw bytes as a QByteArray.

ea7d87b5b5 QHash: Fix erase() edge-case
When the element you want to erase is the last element AND the
next element (element 0), when rehashed, would be relocated to the last
element, this leads to the state below. Which is similar to a test in
tst_qhash for some seeds.

auto it = hash.begin + (hash.size - 1)
it = hash.erase(it)
it != hash.end

By forcing the iterator to increment if we were erasing the last element
we always end up with a pointer which is equal to hash.end

Befriend the tst_qhash class so we can set the seed to a known-bad one

cc64959602 Tidy up tst_QString::localeAwareCompare()
It was suppressed unconditionally (albeit in different places and with
different levels of obviousness) almost everywhere, due to inability
to set the system locale in use by the implementation. Several
test-cases used ISO-8859-1 encoding on Q_OS_MAC, where the tests were
all suppressed anyway. A block of no_NO tests was #if 0'd out; and
should, in any case, have been nb_NO. Tests of any locale but en_US
were skipped on Q_OS_WIN because we can't set the locale (but
including the tests of en_US tacitly assumed that's the system
locale). If setlocale() failed, for ICU or DARWIN, the test was
skipped; but we might as well check for this in the _data() to save
repetition.

The test was laboriously going through the sign cases; relocate the
QString::compare() test's sign() function so that we can use it here,
too, and simply QCOMPARE() signs. Introduce a TransientLocale class,
copied from tst_QLocale, to take care of setting and restoring the
locale using setlocale(). Change the locale name to a QByteArray so
that we save having to convert it to one in order to pass it to
setlocale(). Since that changed every _data() row, reformat those rows
in the process - most of them were long lines.

On the systems where we can't set the locale used by the function
being tested, condition each block of tests in the _data() on whether
LC_COLLATE looks like the locale to be tested, and report how a
determined developer at least can (by repeatedly running the test with
different locales set) test all the cases; and we'll attempt the ones
that we can, when one of the relevant locales is in use. If that
leaves us with no tests we can do, QSKIP() in the _data() to avoid an
assert failure for "Test data requested, but no testdata available."

9661cde161 Apple: Use POSIX IPC instead of System V in sandboxed applications
System V semaphores are not supported in sandboxed applications,
so when Qt is configured with App Store compliance, or the user
requests POSIX IPC explicitly, we use that instead.

https://developer.apple.com/library/archive/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html#//apple_ref/doc/uid/TP40011183-CH3-SW24

As the shared memory name limit on Apple platforms is very low,
we have to skip the existing logic for naming, and instead use
a truncated hash of the key. This should still be fine for
avoiding any collisions in practice.

An explicit check for the ENAMETOOLONG error has been added to
catch any cases where they key goes beyond the allowed length.

Sandboxed applications also have an extra requirement that the
key must include an application group identifier. This requirement
has been pushed up to the user and documented, as we don't have
enough information in Qt to know which identifier to use.

Both tst_QSystemSemaphore and tst_QSharedMemory work as before
with both sandboxed and non-sandboxed applications, after removing
some assumptions in tst_QSharedMemory about System V behavior.

2d51dfbefa Fix and clean up utterly confused (and confusing) transition tests
Various QDateTime tests relating to transitions
* used a nomenclature that made them confusing to thing about; and
* expected identically-initiallized variables to behave differently.

The latter, naturally, lead to "expected fail" tests.

Rewrote the tests to get the date-times they want to test at by means
that avoid the ambiguities inherent in QDateTime's lack of a way to
distinguish the two passes through the repeated hour in a fall-back
(QTBUG-79923) and added commented-out tests indicating what should be
true once that ambiguity is resolved. Verified the DST status is as
expected in the cases where that's the correct distinction between
date-times with the same date and time. Renamed various things to
(hopefully) make them more intelligible.

In the process, purged some leading 0s from numbers in code.

063b421251 Correct handling of last second of 1969 (again)
In my prior attempt to handle the last second of 1969, I forgot that
the QTime we're describing is a local time, so whether *it* thinks
we're at the last second of the day is beside the point. Fortunately,
preceding second should get -2 as return if mktime()'s initial -1
actually meant the last second of 1969, so we can test via that, after
a cheap pre-test to save doing this too often (albeit we only even
attempt the check if mktime() returned -1 in any case).

Restructured qt_mktime() in the process to deal with the error case's
early return promptly instead of doing it in an else clause. Also
repackage the calls to mktime to isolate various quirks and simplify
the logic in qt_mktime(). This also prepares for setting tm_isdst as a
hint when we know when we came from, in massageAdjustedDateTime().

Refined one test, added two more test cases. These didn't fail before
this fix, but a judiciously-placed qDebug() in testing revealed that
localMSecsToEpochMSecs() resorted to its fall-back handling - as if
the date-time were outside the time_t range - due to qt_mktime()
failing, for these test-cases (and several others). This fix evades
that fall-back behavior; a judiciously-placed qDebug() shows none of
our test-cases now fail callMkTime().

4ec5622e62 QSortFilterProxyModel: create mappings on demand again
Calling create_mapping in setSourceModel as introduced by 8455bfee76
can lead to an early call to filterAcceptsRow, and some existing applications may crash.
It is also an incomplete solution since it was only done for the
toplevel index but not for child indexes.

Instead, go back to creating mappings on demand.
This means coming up with a different fix for QTBUG-87781 (dataChanged
not emitted for indexes that haven't been mapped yet, i.e. not queried
or shown anywhere).

When this happens, we can't know if the index was previously filtered
out or not (for lack of a dataAboutToBeChanged signal...). Creating
the mapping with the new data only gives us the new state of affairs,
there's no reference state to compare to. Therefore, when the mapping
is missing (during dataChanged handling), create it, but skip all the
logic about row insertion/removal, just forward the dataChanged signal
if the row isn't filtered out.

Creating the mapping might require creating first mappings for parents,
recursively, which wasn't done anywhere in QSFPM yet, hence the new
create_mapping_recursive() method.

In addition to all this, the handling of removed items was incorrect,
remove_source_items did nothing if the parent was gone, and then
source_items_removed was trying to adjust indexes in an incorrect list.
If the parent is gone, clear the proxy_to_source list, so there's
nothing to adjust afterwards. This bug actually doesn't happen anymore
in this version of the patch, but the change still seems right and might
prevent repeating a long debugging session in the future.

Thanks to ChunLin Wang for the unittest in this commit.

6c1a9f2b4d Simplify storing of notification objects
QPropertyChangeHandler is a templated class and it's argument is
a functor. That makes it inherently cumbersome to use the class
in any context where the change handler needs to be stored.

Introduce a QPropertyNotifier class that stores the functor
in a std::function<void()>, and add a QProperty::addNotifier()
method that can be used instead of onValueChanged().

Also make QPropertyNotifier default constructible.

This significantly simplifies the code that needs to be written
and makes it possible to store notifications as class members
without major hassle.

35412acd88 Use time-zone transition data before 1970 as well as after
QDateTime has long followed a convention of ignoring what it knows
about time-zone transitions before the epoch. This produces unhelpful
artefacts (such as an ahistorical spring-forward skipping the first
hour of 1970 in Europe/London, which was in permanent DST at the time)
and complicates the code. It documented that DST transitions were
ignored, but in fact ignored all transitions prior to 1970 and simply
assumed that the current time-zone properties (half a century later)
applied to all times before 1970.

This appears to be based on the fact that the MS APIs using time_t all
limit their range to after 1970. Given that we have to resort to
"other means" to deal with times after the end of time_t, when it's
only 32-bit (and after year 3000, on MS systems), we have the means in
place to handle times outside the range supported by the system APIs,
so have no need to mimic this restriction. (Those means are not as
robust as we might want, but they are less bad than assuming that the
present zone properites were always in effect prior to 1970.) On
macOS, the time_t functions only reach back to the start of 1900; it
reaches to the end of its time_t range and Linux covers the whole
range. Given this variety, the range is now auto-detected the first
time it is needed (based on some quick and dirty heuristics).

Various CET-specific tests now need adjustments in tests of times
before the introduction of time-zones (when they are in fact on LMT,
not CET). The systemZone() test of QTimeZone can now restore its
pre-zone test cases. Various comments on tests needed updates.

[ChangeLog][QtCore][QDateTime] Available time-zone information is now
used to its full extent, where previously QDateTime used LocalTime's
current standard time for all dates before 1970. Where we have
time-zone information, it is considered reliable, so we use it.  This
changes the "best efforts" used for times outside the range supported
by the system APIs, in most cases giving less misleading results.

5b681bea90 QPropertyBinding: Do not reevaluate if not installed on property
Since we changed binding evaluation to be always eager, we notify and
evaluate all bindings as soon as any dependency changes. This includes
bindings which have been initially installed on a property, but which
were later removed.
With lazy evaluation, we would only notify those bindings and mark them
as dirty, which is unproblematic. With eager evalution, we attempt to
evaluate the binding, though. While that part is still fine, afterwards
we would attempt to write the new value into the property. However,
there is no property at that point, as the binding is not installed.
Instead of adding a check whether the propertydataptr is null, we skip
the reevaluation completely by removing the bindings observers - and
thus the cause for the binding function's reevaluation. As soon as the
binding is set, we reevaluate the function anyway, at which point we
also capture the observers again.

9bad096c09 Use a more forgiving threshold for qFuzzyIsNull(qfloat16)
Analysis of problems with the new test for qFuzzyIsNull() revealed
that, where its version for double uses approximately 4500 * epsilon
and for float used 84 * epsilon as threshold, the qfloat16 version's
value was barely more than epsilon, with the result that the test had
to use a different value than the threshold to pass. (Converting the
threshold from float to qfloat16 and back made it bigger; in effect,
the threshold value was not <= itself.)

Furthermore, comparison with qFuzzyCompare() implied a value of
1/102.5 should be used, roughly 10 * epsilon, for consistency.  When
1/102.5 is rounded to three significant digits (the precision we use
in QTest::toString(), for example), to give 0.00976f as threshold, we
get a value that, after conversion to qfloat16 and back to float, does
give a result <= what we started with. So change qFuzzyIsNull() and
its test to use this as qfloat16's threshold value.

[ChangeLog][QtCore][QFloat16] The qfloat16 threshold value for
qFuzzyIsNull() has changed from 1e-3 to 9.76e-3, almost a factor of
ten increase, for consistency with qFuzzyCompare()'s tolerance. Values
between these would previously have had qFuzzyIsNull(f) false despite
qFuzzyCompre(f, 1+f) being true.

bb5d2af767 Port QPropertyAnimation::targetObject to bindable properties
This is one of the more complicated ports. The target object
was represented by two variables in the past: A raw pointer and a
QPointer. The QPointer is checked in some cases to check whether
the target object still exists.
This patch introduces a targetObjectDestroyed() slot and connects
it to the destroyed(QObject*) signal of the target object.
In this slot, the animation is stopped. The checks become
obsolete thereby and it is sufficient to represent the target
Object in one raw pointer.
This raw pointer becomes a bindable property.

828f533b32 Check POSIX rules during QTzTimeZone creation
Previously, an apparent POSIX rule would be saved and any defects in
it would only be discovered when trying to use it to generate
transitions. Instead, check that it has the right form during the
initial parsing of its data.

In the process, since checking for DST in the process is trivial,
implement a long-standing TODO to cache hasDaylightTime()'s
answer. The array it scanned was in any case being scanned during
construction, so detecting DST in init()'s scan is trivial; and its
failure to check the POSIX rule mean it failed to notice when zones
entirely specified by a POSIX rule have DST.

Adapt a test using a POSIX-only rule to verify it does know the zone
has DST; it did not, before this change.

7fa8315eb1 Fix handling of a POSIX zone rule describing permanent DST
The description necessarily has fake transitions at start and end of
the year, potentially outside the year. These transitions should not
be reported by QTzTimeZonePrivate as transitions, although its data()
must find a "transition" whose data it can use (as in the permanent
standard time case, which could potentially be represented the same
way, although there's a saner way to do so, that the code already
handles) to report the zone's properties.

In the process, fix (and make more straightforward) the convoluted
decision-making code that was deciding which transitions to include in
the returned list. It was assuming invalidMSecs() would be set as the
atMSecsSinceEpoch of a transition, although this is computed in a way
that makes that value most unlikely, even when the result is invalid.
It also rather confusingly mixed < 0 tests as tests for overflow with
the one < 0 test that's about ignoring DST before 1970. Also added
comments to clarify some of what's going on there.

Expanded a recently-added test of a permanent DST zone to verify this
now works correctly.

2383e82bcf Correct the parsing of POSIX rule day-of-year fields
There are two formats for such fields: one with a J prefix on a number
in the range 1 to 365, the other with no prefix and a range from 0 to
365. The code mistakenly treated the latter as if its range were from
1 to 366. The J-form doesn't count Feb 29th, so March always starts on
day 60; the code tried to take that into account, but adjusted in the
wrong direction (and this mislead me, in a recent partial fix, into a
fence-post error).

Add a test-case based on the Africa/Casablanca POSIX rule seen on RHEL
8.2, which tripped over the off-by-one error without a J prefix. This
incidentally also tests the J case.
