a9d51298ae Fix metatype declaration for QHash/QMultiHash with no operator==
When declaring metatypes, the metatype system tries to detect if the
comparison operators for the given type exist and automatically register
them. In case of QHash, the equality operator was enabled if the value
type provides one. But the implementation needs equality operator of
the key type as well. As a result, when the key type has no equality
operator, the metatype system detects that the equality operator is
available for the QHash itself, but the compilation for metatype
registration fails when trying to instantiate the code that uses
equality operator for the key. This is fixed by enabling equality
operators for the QHash only when both the key and value types provide
one.

The same issue existed also for QMultiHash, with the difference, that
QMultiHash didn't have the constraints even on the value type. So added
checks for both.

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.

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

which has the file name on input and is cheap for us because of COW.

"ns" (which stood for "not suitable") to "notfound".

them. We're making a split between "v1" and "baseline" here for the
benefit of 32-bit, which is not included in the ISA levels.

788a7bfdb1 QPlugin: move some of the logic from moc's output to qplugin.h
This will allow us to make changes in QtCore itself, without having to
worry about moc compatibility.

The output uses an #ifdef so this version of moc can still be used to
compile earlier versions of Qt (usually, in cross-compilation
environments). See discussion in the mailing list[1].

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

Unix QThread implementation stores pthread_t as a system thread ID
when the thread is created, but never resets the system ID when
those threads are destroyed. Some implementations may reuse the
same thread IDs for new threads, and this may cause QThread::wait()

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").

7943480f0f Fix QDateTimeParser's handling of 't' format to match serialization
This amends commit 68f19fb630 to only
consume one 't' from the format string, to match qlocale.cpp's
serialization of time-zone specifiers, which only consumes one, so
will repeat the time-zone specifier as many times as unquoted t
appears in the format. It's hard to imagine why anyone would want this
behavior, but it's what our serialization has always done and parsing
should match serialization.

Add test-cases for double time-zone specifier.
Delete a lie in the process.

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.
