Large graphical Qt applications heavily rely on heap allocations.
Jemalloc is a general-purpose malloc(3) implementation designed to
reduce heap fragmentation and improve scalability. It also provides
extensive tuning options.
Add a -jemalloc configure option, disabled by default. When enabled, Qt
and user code link to jemalloc, overriding the system's default
malloc().
Add cooperation with jemalloc for some Qt key classes: QArrayData (used
by QByteArray, QString and QList<T>), QBindingStoragePrivate,
QDataBuffer (used by the Qt Quick renderer), QDistanceFieldData,
QImageData, QObjectPrivate::TaggedSignalVector, QVarLengthArray.
This cooperation relies on two jemalloc-specific optimizations:
1. Efficient allocation via fittedMalloc():
Determine the actual allocation size using nallocx(), then adjust the
container’s capacity to match. This minimizes future reallocations.
Note: we round allocSize to a multiple of sizeof(T) to ensure that
we can later recompute the exact allocation size during deallocation.
2. Optimized deallocation via sizedFree():
Use sdallocx(), which is faster than free when the allocation size
is known, as it avoids internal size lookups.
Adapt the QVarLengthArray auto tests on capacity.
Non-standard functions docs are at https://jemalloc.net/jemalloc.3.html
[ChangeLog][QtCore] Added optional support for the jemalloc allocator,
and optimized memory allocations and deallocations in core Qt classes to
cooperate with it.

This patch changes the generation of the plain-text tag:value SBOM

- standalone tests or examples
- cmake build tests
The JSON SBOM generation and the verification steps have also been

can be found. If the dependencies are not found, the build will
skip the generation and verification steps.
Four new configure options have been added to control these aspects:
-(no-)sbom-json: Allows explicitly enabling or disabling JSON SBOM
generation
-(no-)sbom-json-required: Fails the build if JSON SBOM generation
Python dependencies are not found
-(no-)sbom-verify: Allows explicitly enabling or disabling SBOM

This change adds a new -sbom configure option to allow generating and
installing an SPDX v2.3 SBOM file when building a qt repo.
The -sbom-dir option can be used to configure the location where
each repo sbom file will be installed.
By default it is installed into
$prefix/$archdatadir/sbom/$sbom_lower_project_name.sdpx
which is basically ~/Qt/sbom/qtbase-6.8.0.spdx
The file is installed as part of the default installation rules, but
it can also be installed manually using the "sbom" installation
component, or "sbom_$lower_project_name" in a top-level build. For
example: cmake install . --component sbom_qtbase
CMake 3.19+ is needed to read the qt_attribution.json files for
copyrights, license info, etc. When using an older cmake version,
configuration will error out. It is possible to opt into using an
older cmake version, but the generated sbom will lack all the
attribution file information.
Using an older cmake version is untested and not officially supported.
Implementation notes.
The bulk of the implementation is split into 4 new files:
- QtPublicSbomHelpers.cmake - for Qt-specific collecting, processing
and dispatching the generation of various pieces of the SBOM document
e.g. a SDPX package associated with a target like Core, a SDPX
file entry for each target binary file (per-config shared library,
archive, executable, etc)
- QtPublicSbomGenerationHelpers.cmake - for non-Qt specific
implementation of SPDX generation. This also has some code that was
taken from the cmake-sbom 3rd party project, so it is dual licensed
under the usual Qt build system BSD license, as well as the MIT
license of the 3rd party project
- QtPublicGitHelpers.cmake - for git related features, mainly to embed
queried hashes or tags into version strings, is dual-licensed for
the same reasons as QtPublicSbomGenerationHelpers.cmake
- QtSbomHelpers.cmake - Qt-specific functions that just forward
arguments to the public functions. These are meant to be used in our
Qt CMakeLists.txt instead of the public _qt_internal_add_sbom ones
for naming consistency. These function would mostly be used to
annotate 3rd party libraries with sbom info and to add sbom info
for unusual target setups (like the Bootstrap library), because most
of the handling is already done automatically via
qt_internal_add_module/plugin/etc.
The files are put into Public cmake files, with the future hope of
making this available to user projects in some capacity.
The distinction of Qt-specific and non-Qt specific code might blur a
bit, and thus the separation across files might not always be
consistent, but it was best effort.
The main purpose of the code is to collect various information about
targets and their relationships and generate equivalent SPDX info.
Collection is currently done for the following targets: Qt modules,
plugins, apps, tools, system libraries, bundled 3rd party libraries
and partial 3rd party sources compiled directly as part of Qt targets.
Each target has an equivalent SPDX package generated with information
like version, license, copyright, CPE (common vulnerability
identifier), files that belong to the package, and relationships on
other SPDX packages (associated cmake targets), mostly gathered from
direct linking dependencies.
Each package might also contain files, e.g. libQt6Core.so for the Core
target. Each file also has info like license id, copyrights, but also
the list of source files that were used to generate the file and a
sha1 checksum.
SPDX documents can also refer to packages in other SPDX documents, and
those are referred to via external document references. This is the
case when building qtdeclarative and we refer to Core.
For qt provided targets, we have complete information regarding
licenses, and copyrights.
For bundled 3rd party libraries, we should also have most information,
which is usually parsed from the
src/3rdparty/libfoo/qt_attribution.json files.
If there are multiple attribution files, or if the files have multiple
entries, we create a separate SBOM package for each of those entries,
because each might have a separate copyright or version, and an sbom
package can have only one version (although many copyrights).
For system libraries we usually lack the information because we don't
have attribution files for Find scripts. So the info needs to be
manually annotated via arguments to the sbom function calls, or the
FindFoo.cmake scripts expose that information in some form and we
can query it.
There are also corner cases like 3rdparty sources being directly
included in a Qt library, like the m4dc files for Gui, or PCRE2 for
Bootstrap.
Or QtWebEngine libraries (either Qt bundled or Chromium bundled or
system libraries) which get linked in by GN instead of CMake, so there
are no direct targets for them.
The information for these need to be annotated manually as well.
There is also a distinction to be made for static Qt builds (or any
static Qt library in a shared build), where the system libraries found
during the Qt build might not be the same that are linked into the
final user application or library.
The actual generation of the SBOM is done by file(GENERATE)-ing one
.cmake file for each target, file, external ref, etc, which will be
included in a top-level cmake script.
The top-level cmake script will run through each included file, to
append to a "staging" spdx file, which will then be used in a
configure_file() call to replace some final
variables, like embedding a file checksum.
There are install rules to generate a complete SBOM during
installation, and an optional 'sbom' custom target that allows
building an incomplete SBOM during the build step.
The build target is just for convenience and faster development
iteration time. It is incomplete because it is missing the installed
file SHA1 checksums and the document verification code (the sha1 of
all sha1s). We can't compute those during the build before the files
are actually installed.
A complete SBOM can only be achieved at installation time. The install
script will include all the generated helper files, but also set some
additional variables to ensure checksumming happens, and also handle
multi-config installation, among other small things.
For multi-config builds, CMake doesn't offer a way to run code after
all configs are installed, because they might not always be installed,
someone might choose to install just Release.
To handle that, we rely on ninja installing each config sequentially
(because ninja places the install rules into the 'console' pool which
runs one task at a time).
For each installed config we create a config-specific marker file.
Once all marker files are present, whichever config ends up being
installed as the last one, we run the sbom generation once, and then
delete all marker files.
There are a few internal variables that can be set during
configuration to enable various checks (and other features) on the
generated spdx files:
- QT_INTERNAL_SBOM_VERIFY
- QT_INTERNAL_SBOM_AUDIT
- QT_INTERNAL_SBOM_AUDIT_NO_ERROR
- QT_INTERNAL_SBOM_GENERATE_JSON
- QT_INTERNAL_SBOM_SHOW_TABLE
- QT_INTERNAL_SBOM_DEFAULT_CHECKS
These use 3rd party python tools, so they are not enabled by default.
If enabled, they run at installation time after the sbom is installed.
We will hopefully enable them in CI.
Overall, the code is still a bit messy in a few places, due to time
constraints, but can be improved later.
Some possible TODOs for the future:
- Do we need to handle 3rd party libs linked into a Qt static library
in a Qt shared build, where the Qt static lib is not installed, but
linked into a Qt shared library, somehow specially?
We can record a package for it, but we can't
create a spdx file record for it (and associated source
relationships) because we don't install the file, and spdx requires
the file to be installed and checksummed. Perhaps we can consider
adding some free-form text snippet to the package itself?
- Do we want to add parsing of .cpp source files for Copyrights, to
embed them into the packages? This will likely slow down
configuration quite a bit.
- Currently sbom info attached to WrapFoo packages in one repo is
not exported / available in other repos. E.g. If we annotate
WrapZLIB in qtbase with CPE_VENDOR zlib, this info will not be
available when looking up WrapZLIB in qtimageformats.
This is because they are IMPORTED libraries, and are not
exported. We might want to record this info in the future.

* -ftrivial-auto-var-init=pattern;
* -fstack-protector-strong;

* -Wl,-z,relro,-z,now.
This aligns us 100% with -fhardened (we already pass -fPIE and -pie
anyhow). Some Linux distributions already ship GCC/Clang with some of
these options enabled by default.
The check for Intel CET has been amended to always test if the compiler
supports the corresponding flag; and, if so, enable the feature. Before,
it was behind a configure option and the test only checked if the
compiler had CET support automatically active (the test didn't pass
-fcf-protection to the compiler).
The check for -fstack-protector-strong has been made general (rather
than QNX-specific). We don't support QNX < 7 anyhow.
Finally, the qt_config_linker_supports_flag_test test has been
amended to also support MSVC.
All of the hardening options are enabled by default.

meaning that a series of security-related compiler options are

In Qt 5 times, if Qt was configured with -make examples, running
make install would not only build and install the example binaries,
but would also install the example sources into the prefix.
Installation of example sources was not implemented when the Qt 6
build system has switched to using CMake.
There is still a use case for it though, mainly for Qt Creator, which
only shows the examples of a Qt kit if the sources are available.
In contrast to Qt 5, in Qt 6 we will not install example sources

configure -make examples -install-examples-sources
or
cmake -DQT_BUILD_EXAMPLES=ON -DQT_INSTALL_EXAMPLES_SOURCES=ON
The -make examples part is required, otherwise
-install-examples-sources has no effect.
All example sources can be installed by calling
cmake --install . --component examples_sources
in the qt repo build directory.
In a top-level build, per-repo installation can be done using
cmake --install . --component examples_sources_<repo_name>
where repo_name could be 'qtbase'.
A single example's source can be installed by calling
cmake --install . --component examples_sources_<subdir_name>
where subdir_name is the subdirectory name of the example, e.g.
'gallery'.
Implement installation of example sources by hooking into the
qt_internal_add_example command.
This means that all examples in all repos need to be added via
qt_internal_add_example instead of add_subdirectory, to ensure the
sources are installed. The majority of repos already use it.
For testing purposes one can configure with
-DQT_BUILD_EXAMPLES=ON -DQT_INSTALL_EXAMPLES_SOURCES=ON
-DQT_INTERNAL_NO_CONFIGURE_EXAMPLES=ON to allow testing installation
of examples sources without building them.
Take into account an additional variable called
QT_INTERNAL_EXAMPLES_SOURCES_INSTALL_PREFIX to allow installation of
example sources into a location different from the example binaries.
As a cleanup, the NAME option that could previously be passed to
qt_internal_add_example_external_project has been removed.

- regardless of platform, unless the option was explicitly specified,
we never defaulted to -debug-and-release.
On Windows-MSVC, we always defaulted to Debug. Which is inconsistent
with the rules above.
The difference happens because CMake always sets CMAKE_BUILD_TYPE to
Debug during the first project() call when targeting the Windows-MSVC

We interpreted that as the user setting the build type, and thus we

Merge all the existing checks into a single one, which is a simple pass
or fail, since all our supported compilers support all the intrinsics up
to Cannon Lake. The two I've recently added (AVX512VBMI2 and VAES)
aren't yet supported everywhere, so they stay.
For some reason, all intrinsics seem to be disabled on Android. It looks
like some support was missing during the CMake port and this was never
again looked at. I'm leaving it be.
As for WASM, discussion with maintainers is that the WASM emulation of
x86 intrinsics is too hit-and-miss. No one is testing the performance,
particularly the person writing such code (me). They also have some
non-obvious selection of what is supported natively and what is
merely emulated. Using the actual WASM intrinsics is preferred, but
someone else's job.

Introduce a new -no-prefix option that can be used to build Qt without
having to install it.
Currently, -no-prefix is already implied by -developer-build, but
-developer-build also implies -warnings-are-errors and
-feature-private-tests, which not everyone might want to use.
Some Qt builders likely use -developer-build for the no-prefix
behavior, hence we introduce a standalone -no-prefix option to offer
a nicer user experience without -Werror and friends.
Previously it was possible to achieve the same by specifying
-prefix $PWD, but that relies on $PWD expanding property in the used
shell.
The new -no-prefix doesn't depend on the type of the shell and
is shorter to type.
Internally this gets passed by configure as -DINPUT_no_prefix=yes to
CMake, and transformed into a -DQT_FEATURE_no_prefix=ON feature.
The feature also gets automatically auto-detected to ON if
developer-build is set, -prefix is either unset or $PWD.
CMake code should still query QT_WILL_INSTALL to decide whether
files need to be installed or not.
As a drive-by, we now also export QT_FEATURE_developer_build to
be available for querying during configuration of other repos
(previously it was only possible to query FEATURE_developer_build).

The option is used to specify a list of Qt repos (git submodules)
that should be included in the configuration of a top-level Qt build.
The option takes a comma-separated list of qt submodule names e.g.
'qtbase,qtsvg,qtdeclarative'
It can also take a single value like 'qtbase' or 'qtquick3d'.
Each specified submodule and all of its transitive dependencies will
be included when configuring the top-level Qt build (assuming that the
submodules have previously been already checked out).
Any missing submodules or dependencies will not be automatically
checked out, but rather skipped. This can result in a failed
configuration if a required submodule is missing.
If some optional transitive submodule dependency is not desired in the
build, you can combine the -submodules option together with -skip
options.
E.g. configuring with
-submodules qtdoc,qtnetworkauth -skip qtmultimedia,qtimageformats
will result in a top-level build with the following submodules:
- qtbase (common dependency)
- qttools (dependency of qtdoc)
- qtactiveqt dependency of qttools)
- qshadertools (dependency of qtdeclarative)
- qtdeclarative (explicit)
- qtnetworkauth (explicit)
- qtdoc (explicit)

The -coverage argument merely added compiler flags for the Qt build. It
was never properly ported to the CMake build, and it doesn't seem
feasible to have configure arguments for every possible compiler option.
The same can be achieved by passing the needed compiler option to CMake,
for example: CMAKE_CXX_FLAGS=-fsanitize-coverage=trace-pc-guard

Add new configure option -make minimal-static-tests and CMake option
QT_BUILD_MINIMAL_STATIC_TESTS. In conjunction with QT_BUILD_TESTS
it will enable building a minimal subset of tests when targeting
a static desktop Qt build.
In qtbase the minimal subset includes all the auto tests of testlib,
tools, corelib and cmake. In particular this will also do cmake build
tests and qmake build tests (tst_qmake)
Adjust CI instructions to enable building a minimal subset of static
tests when a platform configuration is tagged with the
