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:

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" ?).

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 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.

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.

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.

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.

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

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.

The operator checks cause compilation errors when trying to check for

Introduced alternative versions of the operator checks (with _container

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

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.

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.
