In the spirit of std::thread, which takes a function to call and its
parameters, and runs it in a new thread. Since the user might want to
connect to signals, move QObjects into the new thread, etc., the new
thread is not immediately started.
Although technically all of this _should_ be implementable in pure
C++11, there is nothing in the Standard to help us not reinvent all the
plumbing: packing the decay'd parameters, storing them, invoking the
function over the parameters (honoring INVOKE/std::invoke semantics).
std::function does not do the job, as it's copiable and therefore does
not support move-only functors; std::bind does not have INVOKE
semantics.
I certainly do not want to reimplement all the required facilities
inside of Qt. Therefore, the full blown implementation requires C++17
(std::invoke).
In order to make this useful also in pre-C++17, there are two additional
implementations (C++11 and C++14) that support just a callable, without
any arguments passed to it. The C++11 implementation makes use of a
class to store and call the callable (even move-only ones); basically,
it's what a closure type for a C++14 lambda would look like.
An alternative implementation could've used some of the existing
facilities inside QObject::connect implementation that store a functor
(for the connect() overload connecting to free functions), namely:
the QtPrivate::QFunctorSlotObject class. However:
* QFunctorSlotObject does not support move-only callables (see
QTBUG-60339);
* QFunctorSlotObject itself is not a callable (apparently by design),
and requires to be wrapped in a lambda that calls call() on it;
* the moment QTBUG-60339 is solved, we'd need the same handwritten
closure to keep QFunctorSlotObject working with move-only callabes.
So: just use the handwritten one.
The C++14 implementation is a simplified version of the C++11 one,
actually using a generalized lambda capture (corresponding to the
handwritten C++11 closure type).
All three implementations use std::async (with a deferred launch policy,
a nice use case for it!) under the hood. It's certainly an overkill for
our use case, as we don't need the std::future, but at least std::async
does all the plumbing for us.

It only contained a concatenation of the individual rule sets,
probably to fix their order in a central place, as well as
simplifying iteration in defaultCategoryFilter().
Fix these two issues differently, but introducing a RuleSet
enum that lists rule sets in the order in which they should
be applied by defaultCategoryFilter(), and turn individual
rule sets vectors into a C array of vectors.
This enables two nested loops in defaultCategoryFilter to
replace the one loop over 'rules'. Apart from building up
'rules' in updateRules(), this was the only access to that
member. That leaves updateRules() with just the task of
running defaultCategoryFilter() on the new rule sets.
Consequently, a call to updateRules() can now replace the
identical loop in installFilter().
Performance should not suffer. Iterating over a fixed-size
array of vectors is hardly any slower than iterating over
a single vector, and while the construction of 'rules'
was probably a one-off task in most programs, this way
of keeping the rules also saves memory because rules are
not kept in two different vectors.
It is also more maintainable, of course.

As for the formatting code, de-duplicate the parsing code by only
parsing char*s, converting QChars to Latin-1 first in a small buffer.
The QUuid(const char*) ctor performed no length checking, relying
instead on the checks performed within _q_uuidFromHex(), which
includes an implicit check for premature end (because NUL is not
a valid token for the parser).
The (QString) and (QByteArray) ctors did perform length checking.
To the extent possible, this is removed, since it is handled by
_q_uuidFromHex(). Failure cases need not be optimized. Only the
QLatin1String overload needs to do some checking, because views in
general are not NUL-terminated. The QStringView overload can just
append a NUL when it converts to Latin-1.
The only check I added to _q_uuidFromHex() is that for src ==
nullptr. It would otherwise be duplicated in several callers.

by value.

Unix mmap(2) system calls do allow for mapping beyond the end of the
file, though what happens after you try to dereference the pointers it
gives is unspecified. POSIX[1] says that implementations shouldn't allow
it:
The system shall always zero-fill any partial page at the end of an
object. Further, the system shall never write out any modified portions
of the last page of an object which are beyond its end. References
within the address range starting at pa and continuing for len bytes to
whole pages following the end of an object shall result in delivery of
a SIGBUS signal.
However, Linux allows this in read-write mode and extends the file
(depending on the filesystem).
Windows MapViewOfFile never allows mapping beyond the end.

We want to prevent
QStringView(QChar|QLatin1String|QByteArray|const char*)
from compiling as QStringView(QString(...)), so I added = delete'ed
ctors for these types to QStringView. However, that makes QStringView
participate in overload resolution for these types. Even if the
QStringView ctor will always fail to compile, the presence of these
ctors alone makes calls to functions overloaded on QString and
QStringView ambiguous:
f(QStringView);
f(QString);
f(foo); // ambiguous
f(QChar('f')) // ambiguous
f(QLatin1String(foo)); // ambiguous
f(QByteArray(foo)); // ambiguous
Fix by making the QString and QStringRef constructors templates
constrained to accept only these two types. This should also help to
move the QStringView definition to before the QString one (as soon as
we get rid of or start to ignore QString::Null), simplifying a lot of
code in qstring.h down the line.
This should also fix MSVC's accepting of two user-defined conversions
which caused static non-compile-tests to fail in the initial
QStringView patch, and which were therefore removed. This patch brings
them back.

QStringView is a simple container for (const QChar*, int) and (const
char16_t*, size_t). It acts as a replacement interface type for const
QString and const QStringRef, and enables passing all kinds of
string-like types to functions otherwise expecting const QString& -
without the need to convert to QString first.
The use of this new class is guarded by a macro that enables three
levels of QStringView support:
1. offer QStringView, overload some functions taking QString with
QStringView
2. like 1, but remove all overloads of functions taking QStringRef,
leaving only the function taking QStringView. Do this only where
QStringRef overloads tradionally existed.
3. like 2, but replace functions taking QString, too.
This is done in order to measure the impact of QStringView on code
size and execution speed, and to help guide the decision of which
level to choose for Qt 6.
This first patch adds QStringView with most of its planned
constructors, but not much more than iterators and isNull()/isEmpty().
Further patches will add support for QStringView to QStringBuilder,
add QStringView overloads of functions taking QString, and add the
complete API of const QString to QStringView.

But these new overloads made existing comparisons to QChar ambiguous.
This was known at the time for QChar/int comparisons.

ie. not comparing to int or char per se is ambiguous, but comparing to
nullptr constants is, because QString(const char*) is just as good a
candidate as QChar(char)/QChar(int).

Some format and parse tests for time and date-time depended on locale
but had test data for the C locale (so fail if the test-environment
has, e.g., LANG=de_DE@utf8). So impose the C locale (until Qt 6).
The date-time test did *some* attempts at fixing for locale, but
failed to handle am/pm; and we do have "### Qt 6" comments in
Q(Date|Time)+::fromString indicating that we intend to switch these
methods to use the C locale by default (which shall fix this once and
for all). So rip out the incomplete localization now and test we work
properly at least when the locale used *is* C. Add a comment to the
matching QDate test to rip out its (presently adequate) matching code
once we do get to Qt 6 and make fromString() use the C locale.
QDateTimeParser uses systemLocale(), which is initialized the first
time it gets accessed; so we need to frob the locale *early*; doing so
in the test-class constructor is about as early as we conveniently
can; and seems to work (while doing it in individual tests does not).
(There is no point rolling back at the end; the QSystemLocale global
has been set up by then, so the roll-back would merely leave the
global out of sync with setlocale() and the environment.)

- strings of 1-65 characters, all different
- strings of 1-65 characters, all the same
- strings of 1-65 characters, all the same *except* the last character
- strings of 16 characters long, all the same except one, and that one
is different for every string (i.e. first string differs in first
char, second in second char, etc)
This should excercise both 1 or more iterations of the vectorized loop,
the detection logic inside the loop, and off-by-one cases.

QChar-QChar comparisson and for QChar-latin1 comparisson.

When a non-QString-backed mode (via the (QChar*, int) ctor) was added
for Qt 4.5, the author forgot to adjust the setCaseSensitivity()
function. It still uses q_pattern instead of (p.uc, p.len) as the
pattern for which to create the skip-table. Since there is no
setPattern() overload for this mode, the correctness of the matcher is
not harmed by this, but its performance degrades to that of a linear
scan: the skip-table, being filled from an empty pattern, will be
all-zeros, sending bm_find() into the 'possible match' case at every
character.
Since matching is still correct, but slow, it's not possible to write
a test for this. I did, however, leave my attempts in the auto-test,
for when we add QStringView overloads of setPattern() which will then
be able to expose the bug.
