Oliver Wolff ae7bc8803f windeployqt: Do not deploy insighttracker plugin by default
Qt insight's TP is using plugin type "generic" so that insight plugins
can be deployed for every Qt application. As "generic" plugins are part
of QtGui windeployqt deploys these if a dependency to QtGui is found.

As defaulting to a deployment of insight plugins might cause confusion
among users, we make deployment of these plugins explicit if the module
is available.

Giuseppe D'Angelo 8cc8bbb466 QOpenGLWidget: use (and prefer) InvalidateFramebuffer
Desktop GL does not have the GL_EXT_discard_framebuffer extension at
all. Instead, it may have GL_ARB_invalidate_subdata.

Furthermore, GLES >= 3.0 and GL >= 4.3 both support FBO invalidation
through glInvalidateFramebuffer.

Extend the semantics of OpenGLExtension::DiscardFramebuffer to mean that
*any* possibility above is supported, and wrap it in a helper function
that calls whatever support is present. (This is all private API
anyhow.) Technically speaking glInvalidateFramebuffer supports a
superset of what glDiscardFramebufferEXT supports, but we never use such
superset, and the two APIs are otherwise identical.

Then, make QOpenGLWidget call that wrapper.

Linux has had it since 2.6.23, which is positively ancient from our
perspective. No one runs Qt on systems anywhere near that old (I'd be
amazed if anyone managed on CentOS / RHEL 7, which carries Linux 3.10).
And we don't deal with ENOSYS on FreeBSD either.

The removal is accomplished by dead code elimination: it's still
compiled on Linux and FreeBSD.

 - use NSDMI in QThreadPipe
 - remove EINTR_LOOP for eventfd_write(3): it can't be interrupted

The install-time code path that's supposed to propagate and install the
metatypes files was never executed, because of a wrong
PARENT_SCOPE assignment and because the code was overriding the meta
type file name retrieved from a property with an empty non-existent

This caused build failures in qtdeclarative when qmlcachegen generated
invalid cpp code without having access to the qtbase foreign types.
This only happened in prefix builds.

Use the appropriate variable for the PARENT_SCOPE assignment and

Ahmad Samir 67129ef9cd QLocaleData: change validateChars() to return validation State
Instead of returning just bool, return a result struct {State,
CharBuff}, a State is useful as it can have an Intermediate state
where the input isn't Acceptable yet, but not Invalid as such. The
example from the linked bug is in tst_QIntValidator::validateFrench(), a
string "1 ", which can be interpretted as a number with a group
separator, but the input shouldn't end with a group separator (changing
the unittest will be done as part of a separate commit).

CharBuff (QVarLengthArray<char, 256>) replaces the QByteArray input
parameter; a QVarLengthArray means no heap allocation in typical
use-cases with input text < 256 characters to validate. This required
minimum changes (QVLA doesn't have startsWith, replaced by comparing
with buff[0]; and for converting to double, wrapped it in a QBAV).

Marc Mutz f82cf6333e Long live QSpan!
QSpan is Qt's version of std::span. While we usually try not to
reimplement std functionality anymore, the situation is different with
QSpan. Spans are non-owning containers, so the usual impedance
mismatch between owning STL and Qt containers doesn't apply here:
QSpan implicitly converts to std::span and vice versa, making STL and
Qt APIs using spans completely interoperable.

We add QSpan mainly for two reasons: First, we don't want to wait
until we require C++20 in Qt and can use std::span. Second, in the
view of this author, some design decisions in std::span hurt the
primary use-case of spans: type-erasure for containers. This results
in two major deviations of QSpan from std::span: First, any rvalue
container is convertible to QSpan, allowing seamless passing of owning
containers to functions taking spans:

    void sspan(std::span<T>);
    void qspan(QSpan<T>);

    std::vector<T> v();
    sspan(v()); // ERROR: rvalue owning container
    auto tmp = v();
    sspan(tmp); // OK, lvalue
    qspan(v()); // OK

This author believes that it's more helpful to have compilers and
static checkers warn about a particular wrong usage than to make
perfectly valid use-cases impossible or needlessly verbose to code.

The second deviation from std::span is that fixed-size span
constructors are also implicit. This isn't as clear-cut, because an
explicit QSpan{arg} isn't per-se bad. However, it means you can't
transparently change from a function taking decltype(arg) to one
taking QSpan and back. Since that's exactly what we intend to do in Qt
going forward, in the interest of source-compatibility, the ctors are
all implicit.

Otherwise, the API of QSpan follows the std::span API very
closely. Like std::span, QSpan isn't equality_comparable, because it's
not clear what equality means for spans (element-wise equal, or (ptr,
size)-wise equal?). The major API additions are Qt-ish versions of std
API functions: isEmpty() on top of empty() and sliced() instead of
subspan(). The (nullary) first()/last() functions (Qt speak for
front()/back()) clash with the std::span function templates of the
same name, so are not provided.

This patch adds QSpan as private API. We intend to make it public API
in the future.

Edward Welbourne ca6a0fd63f QDTP: match local-time by preference to its zone
When parsing a string whose time-zone part matches local time's name,
use local time in preference to the QTimeZone with that name. The case
is ambiguous, and the bug was already fixed (by something else) in
dev, but this caused a failure in 6.2 through 6.5; and using local
time is more natural to QDateTime in any case. The fix incidentally
makes the the logic of the zone-resolution code more straightforward
and a closer match to how findTimeZone() found the match.

The issue was hidden from 6.6 by a change [*] to the handling of POSIX
rules, that lead to plain abbreviations such as CEST and BST - for
which the IANA DB has no entry - no longer being considered "valid"
zones, despite being technically valid POSIX zone descriptors
(effectively as aliases for UTC).

Edward Welbourne c888e3922d Check QDT's local time abbreviation as well as the qTzName()s
Since QDateTime uses some fall-backs if qTzName() doesn't give it
something useful (as happens on MS-Win when local time is UTC),
QDateTimeParser should check the result of those fall-backs as well as
the qTzName()s when checking for local-time as zone.

Edward Welbourne df736da245 Update system collator when system local is default and updates
Amends commit 94de5f9b25 so that every
change to the default locale is reflected in an update to the default
collator used by QString::localeAwareCompare().

Although the change to the system locale does update the QLocaleData
object shared by all system locale objects, the possible change to its
collator() may imply the default collator needs an update; and the
collator backend's init() may use the language, script and territory
that's changed in setting up the revised collator, even if the QLocale
instance referenced has the same QLocaleData.

Marc Mutz 18857db2dd Port QObjectPrivate::connectImpl() to SlotObjUniquePtr internally
... removing the custom scope-guard which was .dismiss()ed too early
(the allocation of 'c' could theoretically fail, and the old code
would leak the slot object in that case; nothing we're generally
guarding against in Qt, but it's a nice drive-by gain, probably shuts
up static checkers, and makes readers wonder less about the lifetime
of the slot object).

As mentioned in the patch porting QObject::connectImpl(), leave the
unique_ptr out of the function's signature, see there for rationale
(key-word: tail-callability).

Marc Mutz 9338207018 Port QObject::connectImpl() to SlotObjUniquePtr internally
This gets rid of the smell that one destroyIfLastRef() call guarded
against nullptr while the other one did not.

Don't change the function signatures, as passing by unique_ptr, while
making the transfer of ownership clear, makes it impossible to call
the function as a tail-call: Non-trivially-copyable arguments live in
the caller's stack frame and the caller has no idea whether the object
was moved from in the callee or not, so it needs to run the dtor,
which prevents this from being tail-callable.

Passing .release(), OTOH, makes it obvious that the unique_ptr is
nullptr afterwards, so leaves the door open for tail-calling.

However, the QObjectPrivate::connectImpl() wasn't, and continues to
not be, a tail-call. Investigating why, while intriguing, is for
another patch (and much more important for the template wrappers of
these functions than then one out-of-line function we're dealing with
here).
