686c02224c QUuid: add the ability to specify the byte order for 128-bit IDs
Some more modern protocols like Bluetooth LE transmit data in little
endian. QtBluetooth will benefit from this.

0f932b9a5d QUuid: add a trivial structure to support exactly 128 bits
This is inspired by QBluetoothUuid's quint128, but with a better
name. It also matches systemd's sd_id128.

1c6bf3e09e Port from container::count() and length() to size() - V5
This is a semantic patch using ClangTidyTransformator as in
qtbase/df9d882d41b741fef7c5beeddb0abe9d904443d8, but extended to
handle typedefs and accesses through pointers, too:

    const std::string o = "object";

    auto hasTypeIgnoringPointer = [](auto type) { return anyOf(hasType(type), hasType(pointsTo(type))); };

    auto derivedFromAnyOfClasses = [&](ArrayRef<StringRef> classes) {
        auto exprOfDeclaredType = [&](auto decl) {
            return expr(hasTypeIgnoringPointer(hasUnqualifiedDesugaredType(recordType(hasDeclaration(decl))))).bind(o);
        };
        return exprOfDeclaredType(cxxRecordDecl(isSameOrDerivedFrom(hasAnyName(classes))));
    };

    auto renameMethod = [&] (ArrayRef<StringRef> classes,
                            StringRef from, StringRef to) {
        return makeRule(cxxMemberCallExpr(on(derivedFromAnyOfClasses(classes)),
                            callee(cxxMethodDecl(hasName(from), parameterCountIs(0)))),
                        changeTo(cat(access(o, cat(to)), "()")),
                        cat("use '", to, "' instead of '", from, "'"));
    };

    renameMethod(<classes>, "count", "size");
    renameMethod(<classes>, "length", "size");

except that the on() matcher has been replaced by one that doesn't
ignoreParens().

Added two NOLINTNEXTLINEs in tst_qbitarray and tst_qcontiguouscache,
to avoid porting calls that explicitly test count().

77eef32917 QLibrary: fix loading multiple versions of a library
The libraryMap only stored the file path, so we couldn't load two
versions of the same library as we'd find the other version already
loaded. Change the map to index by file name and version (using a NUL as
separator, since that can't appear in file names).

[ChangeLog][QtCore][QLibrary] Fixed a bug that caused QLibrary to be
unable to load two different versions of a library of a given name at the
same time. Note that this is often inadviseable and loading the second
library may cause a crash.

636dbe6045 tst_QLibrary: add a cleanup() method to unload left-overs
QLibrary intentionally does not unload on destruction, so failing tests
may leave libraries already loaded and cause further tests to fail
because of that. So add a cleanup() method to unload everything we may
have loaded.

Note that QLibrary::unload() sets its state to NotLoaded after one
successful call, so we must recreate the object in case it had been
load()ed multiple times.

97470a7838 tst_QUuid::fromString(): tweak a test to avoid data-tag collision
Two of the uuidA test cases had an open-brace for the string and no
close; one of them ended with a space (which, apparently, is valid).
Since the data-tag was constructed by formatting the string in a
fixed-width field, padding with spaces, these two cases coincided.

Fortunately the only uuidB test-case had closing as well as opening
braces, so we can just switch the test for "trailing space is not an
error" to use it, instead.

cd4a3a1dc7 CMake: Fix tst_qlibrary to work on macOS with debug builds
The test expects the helper libraries to contain the .dylib suffix
rather than .so.

Replace glob copying of the libraries (which depends on the underlying
shell) with manual copy calls.
This also ensures the libraries don't contain a _debug postfix in the
file name even in a debug build, which would break the tests.

This removes the last QFactoryLoader used with an empty path (also the
only two that could be reached), which were causing a scan of the
application's binary directory whenever the platform plugin path was
set. In case of applications installed to /usr/bin, the entire /usr/bin
was scanned, which can be qualified as "not good".

0ab3c5c250 QPluginLoader/ELF: fix Clang ASan builds
Clang aligns the object at 32-byte boundaries even though we
specifically asked for alignof(void*), so tell it not to sanitize the
address of the plugin object. Tested with Clang 12 and 13.

GCC seems not to be affected, even when ASan is enabled.

If this doesn't work, we may need to accept reading a note that is
improperly aligned. I don't think the output will be actually a correct
note because the intra-note alignment will be wrong (I carefully chose
the ELF note name so it would not require alignment, but that's only
valid up to 8-byte alignments).

8c2969ea86 QPlugin: Move the plugin metadata to a note in ELF platforms
A few systems, like OpenWRT, may strip the section table off the
resulting binaries (see [1]), making it impossible for us to pinpoint
the exact location of the Qt plugin metadata. This commit moves the meta
data to a location that is identifiable even in fully stripped binaries:
an ELF note.

By naming our section ".note.qt.metadata", we instruct the linker to
place it along the other notes and to mark it in the program header
section. Another advantage is that the notes are usually in the very
beginning of the file, as they are used by the dynamic linker itself, so
we'll need to read much less of the full contents.

The unit test is modified not to attempt to strip the plugin of
debugging data. In fact, we add something to the end that would,
otherwise, be matched as (invalid) metadata.

The following was produced with GCC 11 and GNU binutils ld 2.36.1.

Section Headers:

The Qt metadata note is 4-byte aligned and can thus be found in the
second note section, which spans from 0x02d8 to 0x02d8+0xac=0x0384.

GNU readelf -n can even show it:

   description data: 01 06 03 81 bf ...... ff

I chose 0x7451 as the prefix for our notes, even though they're already
namespaced by the owner in the first place, because eu-readelf
mistakenly tries to interpret note 1 as a GNU ABI tag regardless of
owner. The owner name was chosen to be 12 bytes long, so the ELF note
header is 24 bytes in total. There's no space wasted because the payload
needs to be aligned to 32-bit anyway and I didn't want to use only 4
characters (header total size 16 bytes) so we'd skip the "GNU" note on
size, without string comparison. And I couldn't think of a 4-character
representative string ("QtP" ?).

46fc01d7ca QElfParser: rewrite using elf.h
This rewrite uses the actual structures supplied by the system's C
library, so it should be easier to read. It removes hardcoded constants
with little evident meaning in favor of sizeof() and the macros from
that header. It also removes advancing the data pointer in favor of
having absolute offsets.

The resulting implementation is stricter than the original, checking
more fields in the header. Because the QPluginLoader and QFactoryLoader
users may make decisions based on availability of plugins before
attempting to load them, it's better to be stricter here than to fail
later when trying to dlopen() them.

Debugging and testing are much improved. Instead of stored artifacts, I
added a routine to modify a valid plugin to make it invalid, given the
conditions we've found so far.

If you turn debugging on for this category, you'll see things like:

461084b6c4 Q{Elf,Mach}Parser: harmonize the arguments passed
Both functions took a QString for the input file name, but while the ELF
parser had an optional QLibrary pointer (which was never null) where to
store the error string, the Mach-O parser received a pointer to a
QString. So make both of them take a single in/out QString pointer,
which has the file name on input and is cheap for us because of COW.

Drive-by fix the name of the static function in qmachparser.cpp from
"ns" (which stood for "not suitable") to "notfound".

When we created the functionality, the levels were not yet standardized.
Now they are and you can use -march=x86-64-v3 (for example) to get to
them. We're making a split between "v1" and "baseline" here for the
benefit of 32-bit, which is not included in the ISA levels.

This will allow us to make changes in QtCore itself, without having to

The output uses an #ifdef so this version of moc can still be used to
compile earlier versions of Qt (usually, in cross-compilation
environments). See discussion in the mailing list[1].

57960ab075 Q{Elf,Mach}Parser: simplify the return codes
The multi-state return code was a legacy of how Arvid wrote the ELF
parser code back in the day, the fact that it scanned for two different
types of plugins in Qt 4 and that the metadata could exist in different
places.  None of that matters nowadays: who cares if the file is a
corrupt binary, not a valid binary, does not have the right
architecture, or has no suitable section? It's not a plugin, period.

The Qt 4 plugin mechanism was removed for Qt 5.0 in commit
7443895857 ("Remove support for Qt 4 style
plugins").

70df6052d8 tst_QPluginLoader: Simplify creating a fake pointer in fakeplugin.cpp
When assigning multiple variables to a specific section, both GCC
and Clang legitimately error out if those variables wouldn't end
up in the same section (e.g. if one of them is going to a read-only
section while the other one is going to a read-write section).

In C++, when a seemingly const variable needs dynamic initialization,
it needs to be stored in a read-write section.

Clang 13 changed internals for how some constants are materialized.
Now, when a variable is initialized with an expression containing
plain old fashioned casts, it is considered to be potentially
runtime initialized (at the point when section assignment conflicts
is evaluated). Therefore, Clang 13 errors out on fakeplugin.cpp
with errors like:

    fakeplugin.cpp:36:39: error: 'message' causes a section type conflict with 'pluginSection'
    QT_PLUGIN_METADATA_SECTION const char message[] = "QTMETADATA";
                                          ^
    fakeplugin.cpp:32:40: note: declared here
    QT_PLUGIN_METADATA_SECTION void *const pluginSection = (void*)(0xc0ffeec0ffeeL);
                                           ^

See https://bugs.llvm.org/show_bug.cgi?id=51442 for discussion
on the matter in Clang.

To simplify things, just initialize the fake pointers as regular
uintptr_t instead, avoiding the whole matter. This produces the
exact same contents in the section as before.

For what it's worth, the actual manually constructed metadata in
fakeplugin.cpp doesn't seem to have any effect on running the
QPluginLoader tests on either ELF or MachO right now.

92185d417d Fix BASE argument of qt_add_resources
The BASE argument of qt_add_resources now denotes the root point of the
alias of the file.  Before, BASE was merely prepended to every file that
got passed to qt_add_resources.

Old behavior:
    qt_add_resources(app "images"
        PREFIX "/"
        BASE "../shared"
        FILES "images/button.png")

Alias is "../shared/images/button.png", and pro2cmake generated
QT_RESOURCE_ALIAS assignments to fix this.

New behavior:
    qt_add_resources(app "images"
        PREFIX "/"
        BASE "../shared"
        FILES "../shared/images/button.png")

The alias is "images/button.png".  No extra QT_RESOURCE_ALIAS assignment
is needed.

The new behavior is in effect for user projects and for Qt repositories
that define QT_USE_FIXED_QT_ADD_RESOURCE_BASE.  Qt repositories will be
ported one by one to this new behavior.  Then the old code path can be
removed.
