Release notes for 4.2 (mickledore)
----------------------------------

New Features / Enhancements in 4.2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

-  Linux kernel 6.1, glibc 2.37 and ~350 other recipe upgrades

-  Python 3.8+ and GCC 8.0+ are now the minimum required versions on the build host.
   For host distributions that do not provide it, this is included as part of the
   :term:`buildtools` tarball.

-  BitBake in this release now supports a new ``addpylib`` directive to enable
   Python libraries within layers. For more information,
   see :ref:`bitbake-user-manual/bitbake-user-manual-metadata:extending python library code`.

   This directive should be added to your layer configuration
   as in the below example from ``meta/conf/layer.conf``::

      addpylib ${LAYERDIR}/lib oe

-  BitBake has seen multiple internal changes that may improve
   memory and disk usage as well as parsing time, in particular:

   -  BitBake's Cooker server is now multithreaded.

   -  Ctrl+C can now be used to interrupt some long-running operations
      that previously ignored it.

   -  BitBake's cache has been extended to include more hash
      debugging data, but has also been optimized to :yocto_git:`compress
      cache data <https://git.yoctoproject.org/poky/commit/?h=mickledore&id=7d010055e2af3294e17db862f42664ca689a9356>`.

   -  BitBake's UI will now ping the server regularly to ensure
      it is still alive.
 
-  New variables:

   -  :term:`VOLATILE_TMP_DIR` allows to specify
      whether ``/tmp`` should be on persistent storage
      or in RAM.

   -  :term:`SPDX_CUSTOM_ANNOTATION_VARS` allows to add
      specific comments to the :term:`SPDX` description of a recipe.

-  Rust improvements:

   -  This release adds Cargo support on the target, and includes
      automated QA tests for this functionality.

   -  It also supports checksums for Rust crates and makes
      them mandatory for each crate in a recipe.

   -  New :ref:`ref-classes-cargo-update-recipe-crates` class to
      enable updating :term:`SRC_URI` crate lists from ``Cargo.lock``

   -  Enabled building Rust for baremetal targets

   -  You can now also easily select to build beta or nightly
      versions of Rust with a new :term:`RUST_CHANNEL` variable
      (use at own risk)

   -  Support for local GitHub repos in :term:`SRC_URI` as
      replacements for Cargo dependencies

   -  Use built-in Rust targets for ``-native`` builds to save several
      minutes building the Rust toolchain

-  Architecture-specific enhancements:

   -  This release adds initial support for the
      :wikipedia:`LoongArch <Loongson#LoongArch>`
      (``loongarch64``) architecture, though there is no testing for it yet.

   -  New ``x86-64-v3`` tunes (AVX, AVX2, BMI1, BMI2, F16C, FMA, LZCNT, MOVBE, XSAVE)

   -  go: add support to build on ppc64le
   -  rust: rustfmt now working and installed for riscv32
   -  libpng: enable NEON for aarch64 to ensure consistency with arm32.
   -  baremetal-helloworld: Enable x86 and x86-64 ports

-  Kernel-related enhancements:

   -  Added some support for building 6.2/6.3-rc kernels
   -  linux-yocto-dev: mark as compatible with qemuarm64 and qemuarmv5
   -  Add kernel specific OBJCOPY to help switching toolchains cleanly for kernel build between gcc and clang

-  New core recipes:

   - ``debugedit``
   - ``gtk4`` (import from meta-gnome)
   - ``gcr``: add recipe for gcr-4
   - ``graphene`` (import from meta-oe)
   - ``libc-test``
   - ``libportal`` (import from meta-gnome)
   - ``libslirp``
   - ``libtest-fatal-perl``
   - ``libtest-warnings-perl`` (import from meta-perl)
   - ``libtry-tiny-perl``
   - ``python3-build``
   - ``python3-pyproject-hooks``
   - ``python3-hatch-fancy-pypi-readme``
   - ``python3-unittest-automake``

-  QEMU/runqemu enhancements:

   -  Set ``QB_SMP`` with ?= to make it easier to modify
   -  Set ``QB_CPU`` with ?= to make it easier to modify (x86 configuration only)
   -  New ``QB_NFSROOTFS_EXTRA_OPT`` to allow extra options to be appended to the NFS rootfs options in kernel boot args, e.g. ``"wsize=4096,rsize=4096"``
   -  New ``QB_SETUP_CMD`` and ``QB_CLEANUP_CMD`` to enable running custom shell setup and cleanup commands before and after QEMU.
   -  ``QB_DEFAULT_KERNEL`` now defaults to pick the bundled initramfs kernel image if the Linux kernel image is generated with :term:`INITRAMFS_IMAGE_BUNDLE` set to "1"
   -  Split out the QEMU guest agent to its own ``qemu-guest-agent`` package
   -  runqemu: new ``guestagent`` option to enable communication with the guest agent
   -  runqemu: respect :term:`IMAGE_LINK_NAME` when searching for image

-  Image-related enhancements:

   -  Add 7-Zip support in image conversion types (``7zip``)
   -  New :term:`IMAGE_MACHINE_SUFFIX` variable to allow easily removing machine name suffix from image file names

-  wic Image Creator enhancements:

   -  ``bootimg-efi.py``: add support for directly loading Linux kernel UEFI stub
   -  ``bootimg-efi.py``: implement ``--include-path``
   -  Allow usage of ``fstype=none`` to specify an unformatted partition
   -  Implement repeatable disk identifiers based on :term:`SOURCE_DATE_EPOCH`

-  FIT image related improvements:

   -  FIT image signing support has been reworked to remove interdependencies and make it more easily extensible
   -  Skip FDT section creation for applicable symlinks to avoid the same dtb being duplicated
   -  New :term:`FIT_CONF_DEFAULT_DTB` variable to enable selecting default dtb when multiple dtbs exist

-  SDK-related improvements:

   -  Extended the following recipes to nativesdk:

      - ``bc``
      - ``gi-docgen``
      - ``gperf``
      - ``python3-iniconfig``
      - ``python3-atomicwrites``
      - ``python3-markdown``
      - ``python3-smartypants``
      - ``python3-typogrify``
      - ``ruby``
      - ``unifdef``

   -  New :term:`SDK_ZIP_OPTIONS` variable to enable passing additional options to the zip command when preparing the SDK zip archive
   -  New Rust SDK target packagegroup (``packagegroup-rust-sdk-target``)

-  Testing:

   -  The ptest images have changed structure in this release. The
      underlying ``core-image-ptest`` recipe now uses :term:`BBCLASSEXTEND` to
      create a variant for each ptest enabled recipe in OE-Core.

      For example, this means that ``core-image-ptest-bzip2``,
      ``core-image-ptest-lttng-tools`` and many more image targets now exist
      and can be built/tested individually.

      The ``core-image-ptest-all`` and ``core-image-ptest-fast`` targets are now
      wrappers that target groups of individual images and means that the tests
      can be executed in parallel during our automated testing. This also means
      the dependencies are more accurately tested.

   -  It is now possible to track regression changes between releases using
      :oe_git:`yocto_testresults_query.py </openembedded-core/tree/scripts/yocto_testresults_query.py>`,
      which is a thin wrapper over :oe_git:`resulttool
      </openembedded-core/tree/scripts/resulttool>`. Here is an example
      command, which allowed to spot and fix a regression in the
      ``quilt`` ptest::

         yocto_testresults_query.py regression-report 4.2_M1 4.2_M2

      See this `blog post about regression detection
      <https://bootlin.com/blog/continuous-integration-in-yocto-improving-the-regressions-detection/>`__.

   -  This release adds support for parallel ptest execution with a ptest per image.
      This takes ptest execution time from 3.5 hours to around 45 minutes on the autobuilder.

   -  Basic Rust compile/run and cargo tests

   -  New ``python3-unittest-automake`` recipe which provides modules for pytest
      and unittest to adjust their output to automake-style for easier integration
      with the ptest system.

   -  ptest support added to ``bc``, ``cpio`` and ``gnutls``, and fixes made to
      ptests in numerous other recipes.

   -  ``ptest-runner`` now adds a non-root "ptest" user to run tests.

   -  ``resulttool``: add a ``--list-ptest`` option to the log subcommand to list ptest names
      in a results file

   -  ``resulttool``: regression: add metadata filtering for oeselftest

-  New :term:`PACKAGECONFIG` options in the following recipes:

   - ``at-spi2-core``

-  Extended the following recipes to native:

   - ``iso-codes``
   - ``libxkbcommon``
   - ``p11-kit``
   - ``python3-atomicwrites``
   - ``python3-dbusmock``
   - ``python3-iniconfig``

   -  ``create``: add ``-a``/``--add-layer option`` to add layer to ``bblayers.conf`` after creating layer
   -  ``show-layers``: improve output layout

-  Other BitBake improvements:

   -  Improve error message for a missing multiconfig
   -  Switch to a new :term:`BB_CACHEDIR` variable for codeparser cache location
   -  Mechanism introduced to reduce the codeparser cache unnecessarily growing in size

      updated to pass year 2038 tests, and a QA check for 32 bit time and file
      offset functions has been added (default off)

   -  Patch fuzz/Upstream-Status checking has been reworked:

      -  Upstream-Status checking is now configurable from :term:`WARN_QA`/:term:`ERROR_QA` (``patch-status-core``)
      -  Can now be enabled for non-core layers (``patch-status-noncore``)
