The QTimeZone(id) constructor accepts these IDs, but
isTimeZoneIdAvailable() did not admit to this. Although we cannot
sensibly list all 183,047 of them in availableTimeZoneIds(), we should
not claim they are unavailable. The custom QTZ constructor needs to
know when the ID it's been given is an IANA one (to refuse to use it),
so it has to be able ask the backends for "is this IANA", so the UTC
backend still has to report these IDs as invalid, leaving the QDT
frontend to include the check for these offset zones.
Extend isTimeZoneIdAvailable() test to include every offset-zone's ID
within QTZ's recognized range of offsets. Although the actual range
accepted by offsetFromUtcString() is wider, bounded by ±24:59:59, the

Make matching changes in QDTP so that it recognizes these localized

Since the TZ backend resorts to ICU for display names, we got
inconsistent results if they disagree about when transitions happened.
Also, ICU uses the current (or only recent history) names for the
zone, so one currently not doing DST (Africa/Tripoli) doesn't get a
report of its DST name at a historical time when it did DST (but ICU
doesn't know about it). Since the ICU backend, in any case, doesn't
override the displayName(qint64, ...), we can simply use the QTZP base
version instead of overloading in the TZ back-end, so we only delegate
to ICU when it might actually help. This also saves duplicating some
locking and lazy-initialization code.
In the process, turn a unique lock into a scoped lock within a
suitable scope. Also, make a comment more grammatical and less

QDialogButtonBox has logic to automatically resolve a default button,
in case one is not already set via QPushButton directly, or via e.g.
QMessageBox::setDefaultButton().
Unfortunately, this default button can in some cases be overridden by
the first button in the dialog button box. The reason this happens
is that the first button is the focus proxy of the button box, so
when the button box gains focus, it will transfer it to the first
button. And since QPushButtons inside a QDialog have their autoDefault
property set to true by default, this focus transfer will also reset
the default button to the focused button.
This arbitrarily happens for any role that happens to be earlier in
the QDialogButtonBox::ButtonLayout than the AcceptRole, and can be
very confusing for the user, so we try to avoid the situation by
explicitly setting the automatic default button as the focus
widget of the button box, unless one is set already.
This is also what QMessageBox::setDefaultButton() does internally.
The only case we're not covering is when the user sets a push button
as default via QPushButton::setDefault(), but we conservatively
assume that the user then also calls setFocus() on the button.

These special member functions have no purpose.
We never *documented* their semantics. Any code using them is
unconditionally wrong (which semantics was it assuming?), so we can
accept the SIC (type A). If a user needs such a copy, they would have to
reason on the intended semantics (relaxed? acquire/release?) and be
explicit in their code. Especially for assignment, they would need
understand the consequences of the memory ordering that apply on _each_
atomic object involved and not on the assignment operation as a whole
(there are no such semantics).
Testing this change on qtbase has already found bugs.
From a purely technical point of view: we don't guarantee lock-free
atomics nor we require them from the underlying platform. An atomic is
therefore allowed to be implemented as a mutex protecting a value, and
mutexes are not copiable. std::atomic follows the exactly same pattern
(not copiable nor copy-assignable) for exactly the same reasons, and Qt
atomics are implemented on top of std:: ones.
[ChangeLog][QtCore] The copy constructor and assignment operators of
Qt atomic classes (QAtomicInteger, QAtomicPointer) have been removed.
Their usage in user code should be considered a programming error, as no
memory ordering semantics were ever documented for these operations (and
therefore relying on any specific semantic would be relying on
undocumented, unportable behavior). This matches the API of the
std::atomic class in C++. Note that you can still use explicit
load/store operations to transfer a value across two Qt atomic objects,
and therefore use the memory ordering specified for the load/store
operations.

Previously, requesting a time that got repeated - on the given date,
due to a fall-back transition - would get one of the two repeats,
giving the caller (no hint that there was a choice and) no way to
select the other. Add a flags parameter that captures the available
ways to resolve such ambiguity or select a suitable time near a gap.
Add such a parameter to relevant QDateTime methods, including
constructors, to enable callers to indicate their preference in the
same way. This replaces DST-hint parameters in various internal
functions, including QTimeZonePrivate's dataForLocalTime(). Adapted
tst_QDateTime to test the new feature.
Adapt to gap-times no longer being invalid (by default; or, when they
are, no longer having a useful toMSecsSinceEpoch() value). Instead,
they don't match what was asked for. Amend documentation to reflect
that. Most of the code change for this is to QDTParser and QDTEdit.
[ChangeLog][QtCore][QDateTime] Added a TransitionResolution parameter
to various QDateTime methods to enable the caller to indicate, when
the indicated datetime falls in a time-zone transition, which side of
the transition to fall or whether to produce an invalid result.
[ChangeLog][QtCore][Possibly Significant Behavior Change] When
QDateTime is instantiated for a combination of date and time that was
skipped, by local time or a time-zone, for example during a
spring-forward DST transition, the result is no longer marked invalid.
Whether the selected nearby date-time is before or after the skipped
interval may have changed on some platforms; unless overridden by an
explicit TransitionResolution, it is now a date-time as long after the
previous day's noon as a naive reading of the requested date and time
would expect. This was the prior behavior at least on Linux.

... adding a bit of test coverage of keysToValue().
This is not intended as a reproducer for QTBUG-118240, because that
is concerned with inputs valueToKeys() cannot produce.

QPalette specifically has quite a large amount of output (1363
characters) when toString
is called on it. We should make sure that we can fit that in our
failure messages. This patch does that by increasing the limit from
1024 characters to 4096.

The comment in this function made it clear that it really depended on
the size of the pipe buffer in the OS. I don't see a way to make a pipe
default to a different size on Linux -- it always defaults to
PIPE_DEF_BUFFERS (16) and that value is only increased as a result of
fcntl(F_SETPIPE_SZ), which we don't do. But we can be defensive and
simply write until the OS can't take any more data.
Drive-by update the comment on Windows to be clear that bytesToWrite()
does work, but only while the child process is still running.
