bitbake.conf, kernel*.bbclass: include IMAGE_VERSION_SUFFIX only in the _LINK_NAME variables and change it to hard link
* just RFC, the part for images isn't finished yet and there is
still some issue with DATETIME when kernel artifacts are used
from sstate, this is just to validate the idea behind
[YOCTO #12937] before finishing the implementation (it's already
finished and used by various LGE builds, but having simpler
way of doing it directly in oe-core mighe be useful for others).
* move IMAGE_VERSION_SUFFIX from _NAME variables to _LINK_NAME
that way e.g. kernel.do_deploy can be reused from sstate to
provide "version-less" artifacts and then very fast
do_deploy_links task just adds links with consistent suffixes
(by default the version from the recipe but could be easily set
to e.g. some release name when building some products).
* create hard links instead of symlinks, so that whatever version
the filename says is really there
* some IMAGE_FSTYPES might need the "version-less" IMAGE_NAME file
to be removed first or they might either append or update the
content of the image instead of creating new image file from
scratch - I have seen this only with one proprietary format we
generate with our own tool, so hopefully this isn't very common
* this is basically the mechanism are using in webOS with
WEBOS_IMAGE_NAME_SUFFIX which is for official builds set from
jenkins job and then all artifacts (images as well as corresponding
kernel files) have the same version string)
* without this, you can still easily set the variables to contain
the version from jenkins job (excluded from sstate signature like
DATETIME currently is to prevent rebuilding it everytime even when
the content didn't change) but then when kernel is reused from sstate
you can have version 1.0 used on kernel artifacts and 2.0 on image
artifacts.
* if you don't exclude the version string with vardepsexclude, then
you get the right version in the filenames but for cost of
re-executing do_deploy every single time, which with rm_work will
cause all kernel tasks to be re-executed (together with everything
which depends on it like external modules etc).
* the implementation "from outside" is a bit tricky as shown in webOS
OSE, because first you need to reverse the meaning of IMAGE_NAME
and IMAGE_LINK_NAME like here, but also replace all symlinks with
hardlinks and then adjust all recipes/bbclasses to depend on our
do_deploy_fixup task instead of the original do_deploy
see the variable modifications:
https://github.com/webosose/meta-webosose/blob/a35e81622aae1066591e44a132d01297ff478248/meta-webos/conf/distro/include/webos.inc#L65
and then various bbclasses to hook do_webos_deploy_fixup task creating
the hardlinks for possible artifacts:
https://github.com/webosose/meta-webosose/blob/a35e81622aae1066591e44a132d01297ff478248/meta-webos/classes/webos_deploy.bbclass
https://github.com/webosose/meta-webosose/blob/a35e81622aae1066591e44a132d01297ff478248/meta-webos/classes/kernel.bbclass
https://github.com/webosose/meta-webosose/blob/a35e81622aae1066591e44a132d01297ff478248/meta-webos/classes/image.bbclass
so hopefully with all these changes in oe-core other project can
achieve the same just by setting one variable IMAGE_VERSION_SUFFIX
