Further details: + +- :term:`IMAGE_NAME` and :term:`IMAGE_LINK_NAME` now include the + :term:`IMAGE_NAME_SUFFIX` value directly. In practical terms, this means + that ``.rootfs`` will now appear in image output file names. If you do not + wish to have the ``.rootfs`` suffix used, you can just set + :term:`IMAGE_NAME_SUFFIX` to "" and this will now be consistently respected + in both the image file and image file symlink names. As part of this change, + support for the ``imgsuffix`` task varflag has been dropped (mostly + an internal implementation detail, but if you were implementing a custom + image construction with a task in a similar manner to ``do_bootimg`` + you may have been using this). + +- :term:`SDK_NAME` now includes the values of :term:`IMAGE_BASENAME` and + :term:`MACHINE` so that they are unique when building SDKs for different + images and machines. + + + +.. _migration-4.3-pr-pe: + +Versioning changes +~~~~~~~~~~~~~~~~~~ + +- :term:`PR` values have been removed from all core recipes - distro maintainers + who make use of :term:`PR` values would need to curate these already so the + sparsely set base values would not be that useful anymore. If you have been + relying on these (i.e. you are maintaining a binary package feed where package + versions should only ever increase), double-check the output (perhaps with the + help of the :ref:`ref-classes-buildhistory` class) to ensure that package + versions are consistent. + +- The :term:`PR` value can no longer be set from the recipe file name - this + was rarely used, but in any case is no longer supported. + +- :term:`PE` and :term:`PR` are no longer included in the work directory path + (:term:`WORKDIR`). This may break some tool assumptions about directory paths, + but those should really be querying paths from the build system (or not poking + into :term:`WORKDIR` externally). + +- Source revision information has been moved from :term:`PV` to :term:`PKGV`. + The user visible effect of this change is that :term:`PV` will no longer have + revision information in it and this will now be appended to the :term:`PV` + value through :term:`PKGV` when the packages are written out (as long as "+" + is present in the :term:`PKGV` value). Since :term:`PV` is used in + :term:`STAMP` and :term:`WORKDIR`, you may notice small directory naming and + stamp naming changes. + +- The :term:`SRCPV` variable is no longer needed in :term:`PV`, but since + the default :term:`SRCPV` value is now "", using it is effectively now just a + null operation - you can remove it (leaving behind the "+") , but it is not + yet required to do so. + + .. _migration-4.3-qemu-changes: QEMU changes @@ -162,6 +232,11 @@ QEMU changes This change was made to avoid exceeding two serial ports, which interferes with automated testing. +- ``runqemu`` now uses the ``ip tuntap`` command instead of ``tunctl``, and + thus ``tunctl`` is no longer built by the ``qemu-helper-native`` recipe; if + for some reason you were calling ``tunctl`` directly from your own scripts + you should switch to calling ``ip tuntap`` instead. + .. _migration-4.3-misc-changes: Miscellaneous changes |
