Git commit 875d57e3b13390787292cd6495158a3365b0df52 by Qt Cherry-pick Bot (on behalf of Ivan Solovev) on 27/07/2026 at 14:28..
Remove unused variables in qremoteobjectnode.cpp

Found by Axivion static analysis.

Commit e77c98352c584bac7b752dde21c93ff09f78b00d started deserializing
the data directly into a ClassSlot instance, but didn't remove the
now unused local variables. Do it now.

The original commit was merged into 6.9, so picking only down to 6.11.

qremoteobjectsource.cpp: be more explicit on what we delete

In the ranged-for loops over m_children, each 'it' variable is
a QPointer. Calling delete on it is perfectly fine, because it goes
via operator T*().
However, the follow-up change will take 'it' by const-ref instead of
by-value, and then the code will be a bit confusing (i.e. calling
delete on a const ref).

To make it more readable, explicitly call data(), to signal that
we're deleting the underlying data.

Fix Qt-RangeLoopReference warnings

All cases use ranged-for loop to iterate over non-trivially-copyable
data (QVariant, QByteArray, QPointer).
In all cases it's better to take the values by const-ref, rather than
do actual copies.

Amends multiple patches, but all of them preceed Qt 6.8, so it's safe
to pick down to that branch.

Fix Qt-RangeLoopDetach warnings: trivial cases

To prevent detaching, wrap the containers into std::as_const().
If the container is an rvalue, it's impossible to use std::as_const().
In such cases introduce a local const variable.

Fix Qt-RangeLoopDetach: iteration over QMap::keys()

A loop that iterates a map over QMap::keys() and then accesses the
elements via operator[] can be more efficiently replaced with
QMap::asKeyValueRange().

Amends e8cadf8f88128758725ef7498ed7164751095832.
QMap::asKeyValueRange() is available since Qt 6.4, so we can pick the
change to all active branches.

Fix Qt-RangeLoopDetach warning in structured bindings

Several range-for loops are iterating over variables obtained via
structured bindings. The warning was triggered because the variables
are non-const.

Could be fixed in a usual way by wrapping the usages in std::as_const(),
but a better solution would be to initially declare them const.

qremoteobjectnode.cpp: do not use auto when constructing QBA

It deduces the return type to QStringBuilder instead of QByteArray.

Originally pointed out by Axivion, which complains that it can cause
a crash. The complaint is not valid since
qtbase/af8f9a2a6e3dbc865470f8d7f09b533ccea4f353.

However, it is still better to explicitly use QByteArray here.
QStringBuilder does the concatenation every time the variable is used,
instead of doing it once. In this case the variable is used twice, so
using QStringBuilder is less efficient then immediately converting
the result to QByteArray.

Amends c03d630e6d9631791d0668b64025bd82796a55ce (picked to 6.9).
