This is a semantic patch using ClangTidyTransformator as in
qtbase/df9d882d41b741fef7c5beeddb0abe9d904443d8, but extended to
handle typedefs and accesses through pointers, too:
const std::string o = "object";
auto hasTypeIgnoringPointer = [](auto type) { return anyOf(hasType(type), hasType(pointsTo(type))); };
auto derivedFromAnyOfClasses = [&](ArrayRef<StringRef> classes) {
auto exprOfDeclaredType = [&](auto decl) {
return expr(hasTypeIgnoringPointer(hasUnqualifiedDesugaredType(recordType(hasDeclaration(decl))))).bind(o);
};
return exprOfDeclaredType(cxxRecordDecl(isSameOrDerivedFrom(hasAnyName(classes))));
};
auto renameMethod = [&] (ArrayRef<StringRef> classes,
StringRef from, StringRef to) {
return makeRule(cxxMemberCallExpr(on(derivedFromAnyOfClasses(classes)),
callee(cxxMethodDecl(hasName(from), parameterCountIs(0)))),
changeTo(cat(access(o, cat(to)), "()")),
cat("use '", to, "' instead of '", from, "'"));
};
renameMethod(<classes>, "count", "size");
renameMethod(<classes>, "length", "size");
except that the on() matcher has been replaced by one that doesn't
ignoreParens().

We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it
now.
Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.

In Qt 5, QVariant::isNull returned true if either the variant didn't
contain a value, or if the value was of a nullable type where the type's
isNull member function returned true.
In Qt 6, QVariant::isNull only returns true for variants that don't
contain a value; if the value contained is e.g. a null-QString or
QDateTime, then QVariant::isNull returns false.
This change requires a follow up in the SQL drivers, which must
still treat null-values the same as null-variants, lest they write data
into the data base.
Add a static helper to QSqlResultPrivate that implements isNull-checking
of variants that contain a nullable type relevant for Sql, and add a
test case to the QSqlQuery test that exercises that code.

Passing SQLITE_STATIC to sqlite3_bind_*() means that ownership
of the data stays in the caller, i.e. SQLite itself doesn't make a copy;
such data must be therefore be kept valid until sqlite3_step() is called.
The code in the SQLite driver uses that option to avoid copying byte
array or string data. But, unlike what the comments in the code say, we
do NOT keep the QByteArray/QString alive long enough: they're contained
by a temporary QVariant object which gets destroyed at the end of the
loop that binds each argument.
Luckily the fix is simple: since that QVariant is just a copy of the
QVariants used as bound parameters, and these are held in a container
(which lives long enough), simply create a reference to the container's
elements rather than a copy. This ensures that the data is alive by
the time sqlite3_step() is called.
This problem doesn't normally appear because of implicit sharing of
QByteArray/QString. When the QVariant is copied, the inner element
is just a shallow copy. Getting the pointer to the data, and destroying
the QVariant, does not destroy the data (it's kept alive by the
QByteArray/QString inside the *copied-from* QVariant).
Of course there's a catch: if the *copied-from* QVariant contains a
QString created via fromRawData, then everything blows up. In this case,
1. the copied QVariant is created (which bumps the QString refcount)¹
2. the QString inside of it is accessed directly (via
QVariant::constData)
3. utf16() is called on that string, which detaches it (!)
4. the result of utf16() is passed to SQLite, with SQLITE_STATIC
5. the copied QVariant is destroyed; this destroys the inner QString,
which, being detached, deallocates the data too early.
6. sqlite3_step() is called, kaboom.
(The copied-from QVariant still has the string created by fromRawData.)
¹ Note that QString uses the Small QVariant Optimization, so the QString
object itself into the QVariant is copied, it's not just a *QVariant*
refcount increase.

However, those were ignored (other than checking whether the operation
succeeded), causing QSqlError::nativeErrorCode() to always be "-1" when there
was an error while opening/closing the database.
Additionally, the error string needs to be read (via sqlite3_errmsg16) in
