bitbake: include varflags in checksums
Add a dependency to each variable on a filtered list of its varflags. This is intended to catch things such as SRC_URI checksums, varflags controlling extra functionality from classes (e.g. the recently updated update-alternatives class in OE-Core), etc. and ensure their values influence the sstate checksums. There is an exclusion list which needs to be set via bitbake.conf (BB_SIGNATURE_EXCLUDE_FLAGS), if this is not set then the functionality is disabled. The existing vardepsexclude mechanism can also be used to exclude undesired varflags, but they must be fully specified, e.g.: do_patch[vardepsexclude] += "do_patch[someflag]" Implements [YOCTO #2517]. (Bitbake rev: 56c1ab18fcaf4ac245dcb412ed55e8e0af07883b) Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
