1Release 2.7 (warrior) 2===================== 3 4This section provides migration information for moving to the Yocto 5Project 2.7 Release (codename "warrior") from the prior release. 6 7.. _migration-2.7-bitbake-changes: 8 9BitBake Changes 10--------------- 11 12The following changes have been made to BitBake: 13 14- BitBake now checks anonymous Python functions and pure Python 15 functions (e.g. ``def funcname:``) in the metadata for tab 16 indentation. If found, BitBake produces a warning. 17 18- Bitbake now checks 19 :term:`BBFILE_COLLECTIONS` for duplicate 20 entries and triggers an error if any are found. 21 22.. _migration-2.7-eclipse-support-dropped: 23 24Eclipse Support Removed 25----------------------- 26 27Support for the Eclipse IDE has been removed. Support continues for 28those releases prior to 2.7 that did include support. The 2.7 release 29does not include the Eclipse Yocto plugin. 30 31.. _migration-2.7-qemu-native-splits-system-and-user-mode-parts: 32 33``qemu-native`` Splits the System and User-Mode Parts 34----------------------------------------------------- 35 36The system and user-mode parts of ``qemu-native`` are now split. 37``qemu-native`` provides the user-mode components and 38``qemu-system-native`` provides the system components. If you have 39recipes that depend on QEMU's system emulation functionality at build 40time, they should now depend upon ``qemu-system-native`` instead of 41``qemu-native``. 42 43.. _migration-2.7-upstream-tracking.inc-removed: 44 45The ``upstream-tracking.inc`` File Has Been Removed 46--------------------------------------------------- 47 48The previously deprecated ``upstream-tracking.inc`` file is now removed. 49Any ``UPSTREAM_TRACKING*`` variables are now set in the corresponding 50recipes instead. 51 52Remove any references you have to the ``upstream-tracking.inc`` file in 53your configuration. 54 55.. _migration-2.7-distro-features-libc-removed: 56 57The ``DISTRO_FEATURES_LIBC`` Variable Has Been Removed 58------------------------------------------------------ 59 60The ``DISTRO_FEATURES_LIBC`` variable is no longer used. The ability to 61configure glibc using kconfig has been removed for quite some time 62making the ``libc-*`` features set no longer effective. 63 64Remove any references you have to ``DISTRO_FEATURES_LIBC`` in your own 65layers. 66 67.. _migration-2.7-license-values: 68 69License Value Corrections 70------------------------- 71 72The following corrections have been made to the 73:term:`LICENSE` values set by recipes: 74 75- *socat*: Corrected :term:`LICENSE` to be "GPLv2" rather than "GPLv2+". 76- *libgfortran*: Set license to "GPL-3.0-with-GCC-exception". 77- *elfutils*: Removed "Elfutils-Exception" and set to "GPLv2" for shared libraries 78 79.. _migration-2.7-packaging-changes: 80 81Packaging Changes 82----------------- 83 84This section provides information about packaging changes. 85 86- ``bind``: The ``nsupdate`` binary has been moved to the 87 ``bind-utils`` package. 88 89- Debug split: The default debug split has been changed to create 90 separate source packages (i.e. ``package_name-dbg`` and 91 ``package_name-src``). If you are currently using ``dbg-pkgs`` in 92 :term:`IMAGE_FEATURES` to bring in debug 93 symbols and you still need the sources, you must now also add 94 ``src-pkgs`` to :term:`IMAGE_FEATURES`. Source packages remain in the 95 target portion of the SDK by default, unless you have set your own 96 value for :term:`SDKIMAGE_FEATURES` that 97 does not include ``src-pkgs``. 98 99- Mount all using ``util-linux``: ``/etc/default/mountall`` has moved 100 into the -mount sub-package. 101 102- Splitting binaries using ``util-linux``: ``util-linux`` now splits 103 each binary into its own package for fine-grained control. The main 104 ``util-linux`` package pulls in the individual binary packages using 105 the :term:`RRECOMMENDS` and 106 :term:`RDEPENDS` variables. As a result, existing 107 images should not see any changes assuming 108 :term:`NO_RECOMMENDATIONS` is not set. 109 110- ``netbase/base-files``: ``/etc/hosts`` has moved from ``netbase`` to 111 ``base-files``. 112 113- ``tzdata``: The main package has been converted to an empty meta 114 package that pulls in all ``tzdata`` packages by default. 115 116- ``lrzsz``: This package has been removed from 117 ``packagegroup-self-hosted`` and 118 ``packagegroup-core-tools-testapps``. The X/Y/ZModem support is less 119 likely to be needed on modern systems. If you are relying on these 120 packagegroups to include the ``lrzsz`` package in your image, you now 121 need to explicitly add the package. 122 123.. _migration-2.7-removed-recipes: 124 125Removed Recipes 126--------------- 127 128The following recipes have been removed: 129 130- *gcc*: Drop version 7.3 recipes. Version 8.3 now remains. 131- *linux-yocto*: Drop versions 4.14 and 4.18 recipes. Versions 4.19 and 5.0 remain. 132- *go*: Drop version 1.9 recipes. Versions 1.11 and 1.12 remain. 133- *xvideo-tests*: Became obsolete. 134- *libart-lgpl*: Became obsolete. 135- *gtk-icon-utils-native*: These tools are now provided by gtk+3-native 136- *gcc-cross-initial*: No longer needed. gcc-cross/gcc-crosssdk is now used instead. 137- *gcc-crosssdk-initial*: No longer needed. gcc-cross/gcc-crosssdk is now used instead. 138- *glibc-initial*: Removed because the benefits of having it for site_config are currently outweighed by the cost of building the recipe. 139 140.. _migration-2.7-removed-classes: 141 142Removed Classes 143--------------- 144 145The following classes have been removed: 146 147- *distutils-tools*: This class was never used. 148- *bugzilla.bbclass*: Became obsolete. 149- *distrodata*: This functionally has been replaced by a more modern tinfoil-based implementation. 150 151.. _migration-2.7-miscellaneous-changes: 152 153Miscellaneous Changes 154--------------------- 155 156The following miscellaneous changes occurred: 157 158- The ``distro`` subdirectory of the Poky repository has been removed 159 from the top-level ``scripts`` directory. 160 161- Perl now builds for the target using 162 `perl-cross <https://arsv.github.io/perl-cross/>`_ for better 163 maintainability and improved build performance. This change should 164 not present any problems unless you have heavily customized your Perl 165 recipe. 166 167- ``arm-tunes``: Removed the "-march" option if mcpu is already added. 168 169- ``update-alternatives``: Convert file renames to 170 :term:`PACKAGE_PREPROCESS_FUNCS` 171 172- ``base/pixbufcache``: Obsolete ``sstatecompletions`` code has been 173 removed. 174 175- :ref:`native <ref-classes-native>` class: 176 :term:`RDEPENDS` handling has been enabled. 177 178- ``inetutils``: This recipe has rsh disabled. 179 180 181
