qt6_enable_object_libraries_finalizer_mode is not needed anymore
now that static Qt builds require CMake 3.21 and thus CMake takes
care of placing object library object files at the beginning of
the link line.
Rename qt6_enable_import_plugins_finalizer_mode to a more generic
qt6_set_finalizer_mode that can enable or disable multiple
different modes.
For now the only available mode is "static_plugins" which handles
the behavior of the old function name.
The mode can be enabled by calling
qt6_set_finalizer_mode(${target} ENABLE MODES "static_plugins")
Note that the function is re-tagged as being in Technical Preview.
Ideally we would not need it at all. But we need to provide some
workaround for the limitations of linking Qt static plugins in CMake
on Linux-y platforms that use bfd ld or ld.gold.
The workaround does not work well with dependencies wrapped in
generator expressions which is why we can't confidently advertise it
as a proper solution.
Our hope is that this can be fixed in future upstream CMake versions
and the function can be removed.
See 6fcc272ac9 for details.
Adjust the tests due to the renamed and removed functions.

The JUnit test framework did not initially have any XML reporting
facilities built in. Instead, the XML report was generated by the
Apache Ant JUnit task:
https://github.com/apache/ant/search?q=filename%3AXMLJUnitResultFormatter.java
Many users interacted with these reports via the Jenkins JUnit plugin,
which provided graphical visualization of the test results:
https://plugins.jenkins.io/junit/
Due to the lack of an official XML schema for the Apache Ant JUnit
report there was some confusion about what the actual format was.
People started documenting the de-facto format, both as produced
by Ant, and as consumed by Jenkins:
https://github.com/windyroad/JUnit-Schema/blob/master/JUnit.xsdhttps://github.com/junit-team/junit5/search?q=filename%3Ajenkins-junit.xsd
The XML produced by the Qt Test JUnit reporter was far from these
schemas, causing issues when importing results into tools such
as Jenkins, Allure2, or Test Center.
The following changes have been made to improve conformance:
- The 'timestamp' attribute on <testsuite> is is now in ISO
8601 local time, without any time zone specified
- The 'hostname' attribute on <testsuite> is now included
- The 'classname' attribute on <testcase> is now included
- The non-standard 'result' attribute on <testcase> has
been removed
- The non-standard 'result' attribute on <failure> has
been renamed to 'type'
- The <system-out> element on <testsuite> is always included,
even when empty
- The non-standard 'tag' attribute on <failure> has been
removed. Data-driven tests are now represented as individual
<testcase> elements, e.g.:
<testcase name="someTest(someData X)" ...>
<testcase name="someTest(someData Y)" ...>
<testcase name="someTest(someData Z)" ...>
The resulting XML validates against both the de-facto Apache Ant
'JUnit 4' schema and the Jenkins JUnit plugin schema.

To retain backwards compatibility with some QNetworkReply usage,
namely connecting solely to finished-signal and allocating a buffer to
read into, but without storing the entire decompressed file in memory
until read, we may decompress the file twice.
With this patch users can now avoid this double decompression if the
amount of buffered data stays below 10 MiB. This means any file smaller
than 10 MiB will never need to be decompressed twice to know the size of
it. On top of that, if the data is handled as it arrives (e.g. in
readyRead) and the buffer is kept below 10 MiB it won't need to
decompress twice either.
This is active as long as "countDecompressed" is true, though it
currently always is in QNetworkAccessManger, with a future goal to make
it possible to control with public API. Since it requires the user to
potentially adapt their usage of QNetworkReply.
In this patch we also stop tracking the amount of unhandled uncompressed
bytes (uncompressedBytes) in favor of tracking the total amount of bytes
which has been read() by the user of QDecompressHelper (totalBytesRead),
since we can more intuitively work out the total amount of unread bytes
using this value.

We try our best to pass on the file location of a failure, including for
fatal errors, but the reporting or logging machinery should not assume
there is one.
By passing on nullptr for the file location we allow the logging backends
to decide how to handle the situation, e.g. by not emitting extra fields
for failure location.
This effectively reverts c25687fa0b,
in favor of relying on the backends to cope with null filename,
which they already did.
As qFatal uses QMessageLogger, which by default disables file/line
information in release builds, we need to explicitly enable this in
our self-tests, to get uniform test results. Similarly, we disable
file/line info from testlib itself, as reporting Qt internal file
and line information for user diagnostics is less useful. The odd
one out there is qtestdata.cpp, which still ends up in test output
due to using QTEST_ASSERT instead of qFatal for its diagnostics.
Cleaning up that, and unifying how we report testlib issues to the

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

could get away with the same: releasing OpenGL objects underneath,
for example, a QSGPlainTexture with no (or wrong) GL context did
not generate any user visible fatal errors. So we should not crash
in Qt 6 either with these code bases.
In debug builds or when QT_RHI_LEAK_CHECK is set, one will get the

This patch fixed two bugs in indexOf/lastIndexOf:
1. The lastIndexOf(char, qsizetype) overload was crashing with an empty

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)

QByteArrayView implementation. This is done to have similar code paths
in both cases and avoid tricky bugs in future.

C++20 deprecated compound volatile statements such as pre- and
post-increments, to stress that they're not atomic. So instead of
volatile i;
~~~~;
++i;
you're now supposed to write
volatile i;
~~~~;
int j = i; // volatile load
++j;
i = j; // volatile store
which matches more closely what hardware does.
Instead of fixing every use of volatile pre- or post-increment in this
fashion individually, and realising that probably a few more Qt
modules will have the same kind of code patterns in them, write
QtPrivate functions to do the job centrally.

Before this change, next() was the only way to advance the iterator,
whether the caller was ultimately interested in just the filePath()
(good) or not (bad luck, had to call .fileInfo()).
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.
Fix a couple of cases of next(); fileInfo().filePath() (just use
next()'s return value) as a drive-by.

QHash::squeeze() was unconditionally calling reserve(0), which is
always allocating memory (even for 0 size).
This was leading to a confusing situation when calling squeeze() on
a default-constructed container with 0 capacity() actually allocated
memory. This is very misleading, as squeeze() is supposed to free
unneeded memory, not to allocate more.
This patch adds a check for non-zero capacity. As a result, nothing
is done for default-constructed container.
Note that this patch also affects the QSet::squeeze() behavior, because
QSet uses QHash as its underlying data type.

When inserting items into the result store, a ResultItem is created,

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

list isn't empty. Note that empty lists are allowed in some cases for

The plan for QObject::connect() (perfect) forwarders, such as
QWidget::addAction(), was to just use a variant of the Detection Idiom
to see whether QObject::connect() with the arguments as given would
compile and SFINAE out the forwarder otherwise.
It turns out that the "functor" overload of QObject::connect(), in
particular, is severly underconstrained and accepts e.g. QKeySequence
as a function object, only erroring out via a static_assert() in the
body of the function, and thus at instantiation time and not, as
needed, at overload resolution time.
At the same time, we don't really want QObject::connect() to SFINAE
out on argument mismatches between signal and slot, because the
resulting error messages would be ... unkind to users of the API. We
would like to keep the static_assert()s for easier error reporting.
Reconciling these two contradicting requirements has so far eluded
this author, so for now, to unblock progress, we explicitly black-
and, in one case, white-list possible arguments. Because QKeySequence,
in particular, is implicitly constructible from int(!), and therefore
any enum type(!), incl. Qt::ConnectionType, we need to do way too much
coding in the addAction() constraints. Hopefully, we'll be able to fix
the issue at the root cause, in QObject, before Qt 6.3 is out, but
until then, this is an ok-ish stop-gap measure.
Add thorough overload set checks (positive ones only, for now) to
tst_qwidget and tst_qmenu.

Qt has a hardcoded backlog value of 50,
this allows for applications to tune this
value. Modern kernels have the SYN cookie
feature that reduces pressure from an
flood attack, the backlog setting however
is then a queue for most likely real
completed (SYN/ACK) connections hence, it's
easy to get clients connections dropped
with this very small limit.
[ChangeLog][QtNetwork][QTcpServer] Added
QTcpServer::setListenBacklog() to be able
to have control over the listen backlog feature.

The usual pattern (at least in corelib) is tst_bench_[lowercased
class-name] for the test and the same with .cpp for the source-file
name. So s/(main|tst_bench_vector)/tst_bench_qvector/g

Purge comments showing assember from an antique g++ version,
skip #if-ery that's always been on, so makes no difference,
rename two single-letter variables shared between files,
move some extern declarations to a header,
wrap parts of a source file in QT_{BEGIN,END}_NAMESPACE,
add a TODO against an antique commented out #if-ery kludge.
