Subject: metadata_scm.bbclass: Use immediate expansion for the METADATA_* variables
X-Git-Tag: yocto-3.3~174
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=34e1841ec14c545c73fbe03a9f946d43d65ab326;p=openembedded-core.git

metadata_scm.bbclass: Use immediate expansion for the METADATA_* variables

Define METADATA_BRANCH and METADATA_REVISION using immediate expansion.
This avoids running `git rev-parse HEAD` multiple times during recipe
parsing.
