There is no technical reason why qFatal shouldn't support categorized
logging, nor have a streaming version.
There is perhaps an API issue, that is, a streaming syntax may encourage
users to do "too much":
qFatal() << gatherLogs() << saveDatabase() << ...;
and that sounds like a bad idea in case the application is in an
unrecoverable state that requires immedate terminatation (indeed,
through qFatal). I'd err on the side of providing the extra convenience.
This commits adds overloads of QMessageLogger::fatal to support
categorized logging (note that fatal messages cannot be disabled),
the relative qCFatal macro, as well as overloads for streaming.

For both the [4, 7] and [8,15] length cases, we can perform the same
technique: perform two overlapped loads, zero-extend, then perform two
overlapped stores. The 8-character case could be done in a single
load/store pair, but is not worth the extra conditionals. And it should
have the exact same performance numbers whether we use non-overlapping
4-character operations or completely-overlapping 8-character ones (I
*think* the full overlap is actually better).
The 4-character operation is new in this commit. That reduces the
non-vectorized, unrolled to at most 3 characters.

Eventually, we should have the converse operation, too, to complete

qhashfunctions.h defines a catch-all 2-arguments qHash(T, seed)
in order to support datatypes that implement a 1-argument overload
of qHash (i.e. qHash(Type)). The catch-all calls the 1-argument
overload and XORs the result with the seed.
The catch-all is constrained on the existence of such a 1-argument
overload. This is done in order to make the catch-all SFINAE-friendly;
otherwise merely instantiating the catch-all would trigger a hard error.
Such an error would make it impossible to build a type trait that
detects if one can call qHash(T, size_t) for a given type T.
The constraint itself is called HasQHashSingleArgOverload and lives in a
private namespace.
It has been observed that HasQHashSingleArgOverload misbehaves for
some datatypes. For instance, HasQHashSingleArgOverload<int> is actually
false, despite qHash(123) being perfectly callable. (The second argument
of qHash(int, size_t) is defaulted, so the call *is* possible.)
--
Why is HasQHashSingleArgOverload<int> false?
This has to do with how HasQHashSingleArgOverload<T> is implemented: as
a detection trait that checks if qHash(declval<T>()) is callable.
The detection itself is not a problem. Consider this code:
template <typename T>
constexpr bool HasQHashSingleArgOverload = /* magic */;
class MyClass {};
size_t qHash(MyClass);
static_assert(HasQHashSingleArgOverload<MyClass>); // OK
Here, the static_assert passes, even if qHash(MyClass) (and MyClass
itself) were not defined at all when HasQHashSingleArgOverload was
defined.
This is nothing but 2-phase lookup at work ([temp.dep.res]): the
detection inside HasQHashSingleArgOverload takes into account the qHash
overloads available when HasQHashSingleArgOverload was declared, as well
as any other overload declared before the "point of instantiation". This
means that qHash(MyClass) will be visible and detected.
Let's try something slightly different:
template <typename T>
constexpr bool HasQHashSingleArgOverload = /* magic */;
size_t qHash(int);
static_assert(HasQHashSingleArgOverload<int>); // ERROR
This one *does not work*. How is it possible? The answer is that 2-phase
name lookup combines the names found at definition time with the names
_found at instantiation time using argument-dependent lookup only_.
`int` is a fundamental type and does not participate in ADL. In the
example, HasQHashSingleArgOverload has actually no qHash overloads to
even consider, and therefore its detection fails.
You can restore detection by moving the declaration of the qHash(int)
overload *before* the definition of HasQHashSingleArgOverload, so it's
captured at definition time:
size_t qHash(int);
template <typename T>
constexpr bool HasQHashSingleArgOverload = /* magic */;
static_assert(HasQHashSingleArgOverload<int>); // OK!
This is why HasQHashSingleArgOverload<int> is currently returning
`false`: because HasQHashSingleArgOverload is defined *before* all the
qHash(fundamental_type) overloads in qhashfunctions.h.
--
Now consider this variation of the above, where we keep the qHash(int)
overload after the detector (so, it's not found), but also prepend an
Evil class implicitly convertible from int:
struct Evil { Evil(int); };
size_t qHash(Evil);
template <typename T> constexpr bool HasQHashSingleArgOverload = /* magic */;
size_t qHash(int);
static_assert(HasQHashSingleArgOverload<int>); // OK
Now the static_assert passes. HasQHashSingleArgOverload is still not
considering qHash(int) (it's declared after), but it's considering
qHash(Evil). Can you call *that* one with an int? Yes, after a
conversion to Evil.
This is extremely fragile and likely an ODR violation (if not ODR, then
likely falls into [temp.dep.candidate/1]).
--
Does this "really matter" for a type like `int`? The answer is no. If
HasQHashSingleArgOverload<int> is true, then a call like
qHash(42, 123uz);
will have two overloads in its overloads set:
1) qHash(int, size_t)
2) qHash(T, size_t), i.e. the catch-all template. To be pedantic,
qHash<int>(const int &, size_t), that is, the instantiation of the
catch-all after template type deduction for T (= int)
([over.match.funcs.general/8]).
Although it may look like this is ambiguous as both calls have perfect
matches for the arguments, 1) is actually a better match than 2) because
it is not a template specialization ([over.match.best/2.4]).
In other words: qHash(int, size_t) is *always* called when the argument
is `int`, no matter the value of HasQHashSingleArgOverload<int>. The
catch-all template may be added or not to the overload set, but it's
a worse match anyways.
--
Now, let's consider this code:
enum MyEnum { E1, E2, E3 };
qHash(E1, 42uz);
This code compiles, although we do not define any qHash overload
specifically for enumeration types (nor one is defined by MyEnum's
author).
Which qHash overload gets called? Again there are two possible
overloads available:
1) qHash(int, size_t). E1 can be converted to `int` ([conv.prom/3]),
and this overload selected.
2) qHash(T, size_t), which after instantiation, is qHash<MyEnum>(const
MyEnum &, size_t).
In this case, 2) is a better match than 1), because it does not require
any conversion for the arguments.
Is 2) a viable overload? Unfortunately the answer here is "it depends",
because it's subject to what we've learned before: since the catch-all
is constrained by the HasQHashSingleArgOverload trait, names introduced
before the trait may exclude or include the overload.
This code:
#include <qhashfunctions.h>
enum MyEnum { E1, E2, E3 };
qHash(E1, 42uz);
static_assert(HasQHashSingleArgOverload<MyEnum>); // ERROR
will fail the static_assert. This means that only qHash(int, size_t) is
in the overload set.
However, this code:
struct Evil { Evil(int); };
size_t qHash(Evil);
#include <qhashfunctions.h>
enum MyEnum { E1, E2, E3 };
qHash(E1, 42uz);
static_assert(HasQHashSingleArgOverload<MyEnum>); // OK
will pass the static_assert. qHash(Evil) can be called with an object of
type MyEnum after an user-defined conversion sequence
([over.best.ics.general], [over.ics.user]: a standard conversion
sequence, made of a lvalue-to-rvalue conversion + a integral promotion,
followed by a conversion by constructor [class.conv.ctor]).
Therefore, HasQHashSingleArgOverload<MyEnum> is true here; the catch-all
template is added to the overload set; and it's a best match for the
qHash(E1, 42uz) call.
--
Is this a problem? **Yes**, and a huge one: the catch-all template does
not yield the same value as the qHash(int, size_t) overload. This means
that calculating hash values (e.g. QHash, QSet) will have different
results depending on include ordering!
A translation unit TU1 may have
#include <QSet>
#include <Evil>
QSet<MyEnum> calculateSet { /* ... */ }
And another translation unit TU2 may have
#include <Evil>
#include <QSet> // different order
void use() {
QSet<MyEnum> set = calculateSet();
}
And now the two TUs cannot exchange QHash/QSet objects as they would
hash the contents differently.
--
`Evil` actually exists in Qt. The bug report specifies QKeySequence,
which has an implicit constructor from int, but one can concoct infinite
other examples.
--
Congratulations if you've read so far.
=========================
=== PROPOSED SOLUTION ===
=========================
1) Move the HasQHashSingleArgOverload detection after declaring the
overloads for all the fundamental types (which we already do anyways).
This means that HasQHashSingleArgOverload<fundamental_type> will now
be true. It also means that the catch-all becomes available for all
fundamental types, but as discussed before, for all of them we have
better matches anyways.
2) For unscoped enumeration types, this means however an ABI break: the
catch-all template becomes always the best match. Code compiled before
this change would call qHash(int, size_t), and code compiled after this
change would call the catch-all qHash<Enum>(Enum, size_t); as discussed
before, the two don't yield the same results, so mixing old code and new
code will break.
In order to restore the old behavior, add a qHash overload for
enumeration types that forwards the implementation to the integer
overloads (using qToUnderlying¹).
(Here I'm considering the "old", correct behavior the one that one gets
by simply including QHash/QSet, declaring an enumeration and calling
qHash on it. In other words, without having Evil around before including
QHash.)
This avoids an ABI break for most enumeration types, for which one
does not explicitly define a qHash overload. It however *introduces*
an ABI break for enumeration types for which there is a single-argument
qHash(E) overload. This is because
- before this change, the catch-all template was called, and that
in turn called qHash(E) and XOR'ed the result with the seed;
- after this change, the newly introduced qHash overload for
enumerations gets called. It's very likely that it would not give
the same result as before.
I don't have a solution for this, so we'll have to accept the ABI
break.
Note that if one defines a two-arguments overload for an enum type,
then nothing changes there (the overload is still the best match).
3) Make plans to kill the catch-all template, for Qt 7.0 at the latest.
We've asked users to provide a two-args qHash overload for a very long
time, it's time to stop working around that.
4) Make plans to switch from overloading qHash to specializing std::hash
(or equivalent). Specializations don't overload, and we'd get rid of
all these troubles with implicit conversions.
--
¹ To nitpick, qToUnderlying may select a *different* overload than
the one selected by an implicit conversion.
That's because an unscoped enumeration without a fixed underlying type
is allowed to have an underlying type U, and implicitly convert to V,
with U and V being two different types (!).
U is "an integral type that can represent all the enumerator values"
([dcl.enum/7]). V is selected in a specific list in a specific order
([conv.prom]/3). This means that in theory a compiler can take enum E {
E1, E2 }, give it `unsigned long long` as underlying type, and still
allow for a conversion to `int`.
As far as I know, no compiler we use does something as crazy as that,
but if it's a concern, it needs to be fixed.
[ChangeLog][Deprecation Notice] Support for overloads of qHash with only
one argument is going to be removed in Qt 7. Users are encouraged to
upgrade to the two-arguments overload. Please refer to the QHash
documentation for more information.
[ChangeLog][Potentially Binary-Incompatible Changes] If an enumeration
type for which a single-argument qHash overload has been declared is
being used as a key type in QHash, QMultiHash or QSet, then objects of
these types are no longer binary compatible with code compiled against
an earlier version of Qt. It is very unlikely that such qHash overloads
exist, because enumeration types work out of the box as keys Qt
unordered associative containers; users do not need to define qHash
overloads for their custom enumerations. Note that there is no binary
incompatibity if a *two* arguments qHash overload has been declared
instead.

At a certain point in time, QDoc allowed the user the choice between a
custom C++ parser and a Clang based one.
The Q_QDOC symbol would always be defined while the Q_CLANG_QDOC symbol
would be defined only when the Clang based parser was chosen.
In more recent times, QDoc always uses a Clang based parser, such that
both Q_CLANG_QDOC and Q_QDOC are always defined, making them equivalent.
To avoid using different symbols, and the possible confusion and
fragmentation that derives from it, all usages of Q_CLANG_QDOC are now
replaced by the equivalent usages of Q_QDOC.

The zlib convenience API we've been using so far has two problems:
- On Windows-64, where sizeof(long) == 4, the use of ulong for sizes
meant that we could not compress data compressable on other 64-bit
platforms (Unix). While zstream also uses ulong, being a stream API,
it allows feeding data in chunks. The total_in and total_out members
are only required for gzip compression and are otherwise just
informational. They're unsigned, so their overflow does not cause
UB. In summary, using zstream + deflate() allows us to compress more
than 4GiB of data even on Windows-64.
- On all platforms, we always allocated the output buffer in such a
way as to accommodate the pathological case of random, incompressible
data, so the output buffer was larger than the input. Using zstream
+ deflate(), we can start with a smaller buffer, then let zlib pick
up where it left off when it ran out of output buffer space, saving
memory in the common case that compression meaningfully reduces the
size. To avoid the first few rounds of reallocations, we continue to
use zlib's compressBound() for input less than 256KiB.

let zlib pick up where it left off when it ran out of output buffer
space. In all but the most pathological cases, copying the
already-decoded data instead of re-decoding it again should be
faster, esp. if QArrayData uses realloc() instead of malloc() +
free() to grow the buffer.
We also now directly allocate at least as much output buffer as we
have input, to cut the first few rounds of reallocations when the

then we can map Q_UNREACHABLE_RETURN(...) to Q_UNREACHABLE() without

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.

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/.

Two of the uuidA test cases had an open-brace for the string and no

Since the data-tag was constructed by formatting the string in a

Fortunately the only uuidB test-case had closing as well as opening
braces, so we can just switch the test for "trailing space is not an

Given a QTaggedPointer, users may write
taggedPtr = {};
to mean "reset it". This is error-prone: due to overload resolution,
this actually ends up calling QTaggedPointer<T>::operator=(T *),
which changes the pointer but *not* the tag, and not the implicitly
declared QTaggedPointer<T>:operator=(const QTaggedPointer<T> &)
which would reset both pointer and tag.
Given the idiomatic usage of {} is indeed to perform a full reset (cf.
std::exchange(obj, {}), std::take, etc.), work around this by disabling
the operator= overload for pointers in case an initializer list is
passed. In other words, make `={}` fall back to the implicitly
declared overload.
Note, this breaks some usages, such as
taggedPtr = {rawPtr};
but at least we get a compile error for these, and they don't look

Before searching, foldCase the first up to 256 characters, and use this
buffer to compare against the haystack. If the needle is larger than the
buffer, compare the rest of the needle against the rest of the haystack
for every potential match. The buffer is placed on the stack and must be
refolded for each search, but this change does not break the API.
This is faster than the old implementation, except if the needle is long
and it is found near the beginning of the haystack, or if the needle is
long and it is not found in a short haystack where few comparisons are
done and hence few case foldings were needed in the old implementation.

To support cancellation of continuations attached via the parent future,
for each future returned by a continuation we store a pointer to its
parent (i.e. future the continuation is attached to). Later, before
executing a continuation, we go through chain of parents and check if
any of them is cancelled. However, if one of the parents is destroyed
while the chain is executing, the next continuations' parent pointers
will become invalid. So storing the parent pointers isn't safe.
This commit changes the logic of handling the cancelled continuation
chain in the following way:
- Instead of storing a parent pointer in the continuation future's data,
we do the opposite: we store a pointer to continuation's future in the
parent.
- When a future is cancelled, we mark all continuation futures in the
chain with a flag indicating that the chain is cancelled.
- To guarantee that the pointers to continuation future's data don't
become invalid, we clean the continuation (that stores a copy of its
future's data and keeps it alive) only when the associated promise
is destructed, instead of cleaning it after the continuation is run.

The collection of translations available to us need not have anything
to do with whether CLDR has matching data, so preserve the system UI

the QLocale constructor's exercise of likely sub-tag rules.
Instead, simply parse the given locale tags to QLocaleId instances and
use these in the likely-subtag processing to determine what other
entries to add to the list in addition to those supplied by the
operating system. Since going via QLocale did usually supply a
territory, that was included in the BCP 47 name, it's now possible for
the given entry to lack the language_territory name, so be sure to add
that if missing.
This incidentally reduces heap traffic and saves a fair deal of hidden
likely-subtag processing in calls to the constructor and bcp47Name().
Expand testing of QLocale::uiLanguages(), both plain and system. In
the process, cross-link the two closely-related tests, move a comment
on one's _data() to the other's, where it really belongs, and add
reporting of the actual lists on failure. Enable MySystemLocale to
remember the requested locale's ID, before likely sub-tag processing,
so that we can make query() report results for language, script and
territory as requested, to ensure the fake system locale really does
match what was requested. The new german-britain test failed without

The test expects the helper libraries to contain the .dylib suffix

Replace glob copying of the libraries (which depends on the underlying

This also ensures the libraries don't contain a _debug postfix in the

QMetaType already copes with multiple copies NOT getting merged. So we
may as well ask the linkers not to bother and use simpler, local
relocations to find those symbols.
They are all supposed to still be equivalent and it's an ODR violation
if they're not.

The old code assumed that a QByteArray's data() is always
NUL-terminated. Due to the conflation of owners and non-owners in
QByteArray (but also in case we ever get efficient substringing), this
is not always the case, e.g. QByteArray::fromRawData() does not ensure
NUL-termination.
From QString::utf16(), we learn that the condition to check for is
QArrayData::isMutable(). After working around the fact that
QByteArray::data_ptr() doesn't exist for const QBAs and that empty
QBAs always refer to QByteArray::empty_, which is !isMutable(), we can
detect this situation and re-allocate without introducing new API.

Problem description:
--------------------
Assume we have two properties, P1 and P2. Assume further that we assign
a binding to P2, so that it depends on P1. Let the binding additionally
capture some (non-QProperty) boolean, and only create the dependency to
P1 if the boolean is true.
The state afterwards is
P1:[p1vaue|firstObserver]
|
|
v
---[p2binding]
/
P2:[p2value|binding]
If the boolean is set to false, and P1 changes its value, we still
correctly re-evaluate the binding and update P2's value. However, during
binding evaluation we will notice that there is no further dependency
from P2 on P1, and remove its observer.
The state afterwards is
P1:[p1vaue|firstObserver=nullptr]
---[p2binding]
/
P2:[p2value|binding]
Then, during the notify phase, we traverse the observer's again,
starting from P1's firstObserver. Given that it is nullptr now, we never
reach P2's binding, and thus won't send a notification from it.
Fix:
----
We store a list of all visited binding-observers (in a QVarLengthArray,
to avoid allocations as long as possible). After the binding evaluation
phase, we then use that list to send notifications from every binding
that we visited. As we already have a list of all bindings, we no longer
need to recurse on binding-observes during the notification process;
instead, we only need to deal with static callbacks and ChangeHandlers.
The pre-existing notification logic is still kept for the grouped update
case, where we already have a list of all delayed properties, and should
therefore not encounter the same issue. Unifying its codepath with the
existing logic is left as an exercise for a later patch.

This goes against our decision that every time that there's a possible

issue here is possible, but tricky -- since QRegularExpression
is out-of-line, one needs a type-erased container for the input
string (basically, std::any) to keep it alive and so on.
Instead I went for the simpler solution: deprecate match(QStringView)

users are supposed to keep the source object alive.

QString has several functions taking a QRegularExpression: indexOf(),
contains(), and so on. Some of those have an out-argument of type
QRegularExpressionMatch, to report the details of the match (if any).
For instance:
QRegularExpression re(...);
QRegularExpressionMatch match;
if (string.contains(re, &match))
use(match);
The code used to route the implementation of these functions through
QStringView (which has the very same functions). This however opens
up a lifetime problem with temporary strings:
if (getString().contains(re, &match))
use(match); // match is dangling
Here `match` is dangling because it is referencing data into the
destroyed temporary -- nothing is keeping the string alive. This is
against the rules we've decided for Qt, and it's also asymmetric with
the corresponding code that uses QRegularExpression directly instead:
match = re.match(getString());
if (match.hasMatch())
use(match); // not dangling
... although we've documented not to do this. (In light of the decision
we've made w.r.t. temporaries, the documentation is wrong anyways.)
Here QRE takes a copy of the string and stores it in the match object,
thus keeping it alive.
Hence, extend the implementation of the QString functions to keep a
(shallow) copy of the string. To keep the code shared as much as
possible with QStringView, in theory one could have a function taking a
std::variant<QString, QStringView> and that uses the currently active
member. However I've found that std::variant here creates some abysmal
codegen, so instead I went for a simpler approach -- pass a QStringView
and an optional pointer to a QString. Use the latter if it's loaded.
QStringView has some inline code that calls into exported functions, so
I can't change the signature of them without breaking BC; I'm instead
adding new unexported functions and a Qt 7 note to unify them.

This adds support for additional codecs to QStringConverter when ICU is
available.
We store the converter in the state (d[0]), and its canonical name in
d[1]. We need the name there, as in the clear function we close the
UConverter, and set the pointer to null. Consequently, the actual
conversion functions might need to re-open the converter again. The
advantage of this approach is that clear is used in the destructor of
State, and with this approach we properly clean up the state.
There is however a disadvantage: The clear function was so far also used
for resetting the state when QStringConverter::resetState . Discarding
the whole Uconverter for that is however rather costly. For that reason
we modify resetState to call a new function, State::reset. For existing
converters, it behaves the same as clear; for the ICU based converter,
we call the more efficient ucnv_reset. Code compiled against Qt 6.4 can
benefit from this more efficient version; code compiled against older Qt
versions will continue to work, as the conversion functions can just
recretate the converter from the name.
We can distinguish between ICU and non-ICU converters by checking if the
UsesIcu flag is set.
QStringConverter::name is changed to return the name stored in d[1]. The
interface of the ICU converter has a dummy name, so code using the old
name function from QT < 6.4 still returns something, namely a message
asking the user to recompile.
The function is moved out of line, as we need to check for the private
ICU feature, and want to avoid having that check in the public header.
As the QStringConverter ctor taking a name now can allocate memory, it
can no longer be noexcept. Removing the noexceptness is safe, as it was
only added after Qt 6.3.
Note that we cannot extend the API consuming or returning Encoding, as
we use Encoding values to index into an array of converter interfaces in
inline API.
Further API to support getting an ICU converter for HTML will be added
in a future commit.
Currently, the code depending on ICU is enabled at compile time if ICU
is found. However, in the future it could be moved into a plugin to
avoid a hard dependency on ICU in Core.

[ChangeLog][QTestLib] QCOMPARE now evaluates toString() on its

defer toString() invocation until the comparison fails.

As with method signatures, register class names using template function
specialization in the QtJniTypes namespace, and then declare C++ types
as JNI classes with a class name string. Such classes implicitly get
registered as JNI types as well.
Add a QJniObject construct method (since C++ constructors that are
templates cannot be explicitly instantiated with a type), and a
QJniEnvironment::findClass overload.
Add test coverage, also for the recently added macros for native
methods.
As a drive-by, change the name of the Q_JNI_DECLARE_NATIVE_METHOD
macro to Q_DECLARE_JNI_NATIVE_METHOD for consistency.

string from a free function, which are used as native callbacks methods
from Java.
Provide a macro that defines a signature object, and a JNINativeMethod
object based on it, in an internal namespace so that we don't pollute

Add another macro to get the generated JNINativeMethod object based on

Lastly, add overloads to QJniEnvironment::registerNativeMethods that
take a std::initializer_list of JNINativeMethods.
We can now declare a free function to be a JNI native method:
static bool callbackFromJava(JNIEnv *e, jobject /*thiz*/, jstring p1)
{
// ...

Q_JNI_DECLARE_NATIVE_METHOD(callbackFromJava);
and register it with the JNI environment like this:
QJniEnvironment jni;
jni.registerNativeMethods(clazz, {
Q_JNI_NATIVE_METHOD(callbackFromJava)
});

This allows us to specialize JNI type signature templates for e.g. the
context object, which in Java signatures is "android/content/Context".
Introduce a Q_DECLARE_JNI_TYPE macro that takes care of the plumbing.
The types declared this way live in the QtJniTypes namespace, and
transparently convert from and to jobject. Since jobject is a typedef
to _jobject* we cannot create a subclass. Use a "Object" superclass
that we can provide a QJniObject constructor for so that we don't
require the QJniObject declaration to be able to use the macro.
The APIs in the QNativeInterface namespace doesn't provide source or
binary compatibility guarantees, so we can change the return types.

This allows the compiler to deduce the template arguments based on the
provided method parameters, which we can then pass to the methodSignature
and fieldSignature helpers to generate the signature string completely at
compile time.
Since we can't partially specialize template member functions, replace
the specializations for void methods with compile-time-if branches in
the general templates.
This variadic template now prevents implicit conversion from the
LiteralStorage types to const char* signatures, so catch the case where
such a type ends up in the parameter list.
Due to overload resolution rules for constructors, we need to explicitly
disable the constructor if any of the arguments is a string literal type,
as we have to keep the old C-style variadic function working for such
calls.
Add variations that use the variadic templates to the unit tests.
