Having already caught some bugs in real code because of unchecked calls
to QFile::open, this commit marks QFile::open (and open() in other
file-I/O classes) as [[nodiscard]].
Since it's going to raise warnings, the plan is to keep the existing
behavior up to and including the next LTS. Then the warnings will switch
on by default. All of this is protected by system of macros to opt-in or
opt-out the behavioral change at any time.
A possible counter-argument for doing this is that QFile::open is also
used for opening files in the the resource system, and that opening
"cannot fail". It clearly can, if the resource is moved away or renamed;
code should at a minimum use a Q_ASSERT in debug builds. Another
counter-argument is the opening of file handles or descriptors; but
again, that opening may fail in case the handle has been closed or if
the flags are incompatible.
---
Why not marking *every* open() override? Because some are not meant to
be called directly -- for instance sockets are supposed to be open via
calls to `connectToHost` or similar.
One notable exception is QIODevice::open() itself. Although rarely
called directly by user code (which just calls open() on a specific
subclass, which likely has an override), it may be called:
1) By code that just takes a `QIODevice *` and does something with it.
That code is arguably more rare than code using QFile directly.
Still, being "generic" code, they have an extra responsibility when
making sure to handle a possible opening failure.
2) By QIODevice subclasses, which are even more rare. However, they
usually ignore the return from QIODevice::open() as it's
unconditionally true. (QIODevice::open() doesn't use the protected
virtual pattern.)
I'll try and tackle QIODevice in a future commit.
[ChangeLog][QtCore][QFileDevice] The open() functions of file-related
I/O classes (such as QFile, QSaveFile, QTemporaryFile) can now be marked
with the "nodiscard" attribute, in order to prevent a category of bugs
where the return value of open() is not checked and the file is then
used. In order to avoid warnings in existing code, the marking can be
opted in or out, by defining QT_USE_NODISCARD_FILE_OPEN or the
QT_NO_USE_NODISCARD_FILE_OPEN macros. By default, Qt will automatically
enable nodiscard on these functions starting from Qt 6.10.

Most of the cases, a file handle (stdin/out) is opened without checking
for error. That operation may still fail, so check for it.

Inline namespaces serve the purpose for which the original
-qtnamespace option was added and allow for macro simplification (no
need for any using directives). This makes it possible to use
namespaced builds of Qt also for Qt for Python and similar use cases
which have issues with the additional namespace.
[ChangeLog][QtCore] It is now possible to use an inline namespace for
-qtnamespace (option -qtinlinenamespace).

- Initialize members in-class, and in ctor init-list as needed. This
simplifies the constructor and is generally safer as one can't forget
to initialize a member, especially built-in types
- Add copy control members, this is actually a move only class because
of the QMultiHash<QString, RCCFileInfo*> member and the destructor
calling qDeleteAll
- Minor, save a couple of bytes by reordering the members so that they
are in 8 byte chunks as much as possible, sizeof(*this) is now 104,
was 120

hold the result of the concatenation), reuse the existing QString, and
use prepend which will typically have allocated extra space, reducing

retain the file nodes in the resource file system, but remove their

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/.

This patch allows tools to be built for the target platform when the
QT_BUILD_TOOLS_WHEN_CROSSCOMPILING parameter is set at configuration
time.
To avoid naming conflicts, the target tools are suffixed with "_native".
The qt_get_tool_target_name() function can be used to get the tool name
for both scenarios (cross and non-cross compilation).
Extend pro2cmake to refer to the right target name for tools.
The relevant write_XXX functions have a new target_ref parameter that
will be "${target_name}" for tools and literally the target name for
everything else.
