Mention that QtMessageHandler needs to be reentrant,
as well as other caveats. Mention QLoggingCategory,
so people do know that they don't have to necessarily
implement their own handler to filter messages (and that
not all messages reach the handler). Also mention
qFormatLogMessage().
Finally, give a more useful example for a custom
message handler that logs to a file. Note that the example
leaks a file handle at exit, but that is arguably not that
bad.

This is a combination of Q_UNREACHABLE() with a return statement.
ATM, the return statement is unconditionally included. If we notice
that some compilers warn about return after __builtin_unreachable(),
then we can map Q_UNREACHABLE_RETURN(...) to Q_UNREACHABLE() without
having to touch all the code that uses explicit Q_UNREACHABLE() +
return.
The fact that Boost has BOOST_UNREACHABLE_RETURN() indicates that
there are compilers that complain about a lack of return after
Q_UNREACHABLE (we know that MSVC, ICC, and GHS are among them), as
well as compilers that complained about a return being present
(Coverity). Take this opportunity to properly adapt to Coverity, by
leaving out the return statement on this compiler.
Apply the macro around the code base, using a clang-tidy transformer
rule:
const std::string unr = "unr", val = "val", ret = "ret";
auto makeUnreachableReturn = cat("Q_UNREACHABLE_RETURN(",
ifBound(val, cat(node(val)), cat("")),
")");
auto ignoringSwitchCases = [](auto stmt) {
return anyOf(stmt, switchCase(subStmt(stmt)));
};
makeRule(
stmt(ignoringSwitchCases(stmt(isExpandedFromMacro("Q_UNREACHABLE")).bind(unr)),
nextStmt(returnStmt(optionally(hasReturnValue(expr().bind(val)))).bind(ret))),
{changeTo(node(unr), cat(makeUnreachableReturn,
";")), // TODO: why is the ; lost w/o this?
changeTo(node(ret), cat(""))},
cat("use ", makeUnreachableReturn))
);
where nextStmt() is copied from some upstream clang-tidy check's
private implementation and subStmt() is a private matcher that gives
access to SwitchCase's SubStmt.
A.k.a. qt-use-unreachable-return.
There were some false positives, suppressed them with NOLINTNEXTLINE.
They're not really false positiives, it's just that Clang sees the
world in one way and if conditonal compilation (#if) differs for other
compilers, Clang doesn't know better. This is an artifact of matching
two consecutive statements.
I haven't figured out how to remove the empty line left by the
deletion of the return statement, if it, indeed, was on a separate
line, so post-processed the patch to remove all the lines matching
^\+ *$ from the diff:
git commit -am meep
git reset --hard HEAD^
git diff HEAD..HEAD@{1} | sed '/^\+ *$/d' | recountdiff - | patch -p1

the #if-ery is used might actually make sense for those versions.)

Q_MOVABLE_TYPE was conceived before C++ had move semantics. Now, with
move semantics, its name is misleading. Q_RELOCATABLE_TYPE was
introduced as a synonym to Q_MOVABLE_TYPE. Usage of Q_MOVABLE_TYPE
is discouraged now. This patch replaces all usages of Q_MOVABLE_TYPE
by Q_RELOCATABLE_TYPE in QtBase. As the two are synonymous, this
patch should have no impact on users.

When these docs were written, the context.file and context.function
pointers were never null. But in commit d78fb442d750b33afe2e41f31588ec94
(Qt 5.4), we made the logging pass null pointers in release builds. The
C standard does not say that passing null pointers is permitted. In
fact, it says "If no l length modifier is present, the argument shall be
a pointer to the initial element of an array of character type." and
that's pretty explicit that it needs to point to the initial element of
a string.

These uses of Q_QDOC cause clang to report syntax errors.
They are used to hide function return values as qreal
instead of using double and float. The decision is to be
more transparent and use double and float in the docs
instead of qreal.
This change does not require clang in qdoc.

QString::asprintf() has the ability to take a ushort* array as
obtained from QString::utf16() and insert that into the output
with an %ls conversion.
But no-one ever used this, because just passing QString::utf16()
to QString::asprintf() creates a warning about wchar_t* expected,
but ushort* provided.
The new qUtf16Printable() macro adds the necessary casts (via void*
to prevent any "type-punned pointer" warnings) to make
passing QString::utf16() to QString::asprintf() work silently.
This should greatly reduce the need to do a round-trip via utf-8
just to print the contents of a QString.
[ChangeLog][QtCore] Added qUtf16Printable().

This change fixes most qdoc errors in QtCore. There are about 900 left.
The main thing this change does is moving documentation from qtcore from
/doc/src to /src/corelib/doc.
Other issues resolved are mis-use of qdoc commands.
