The current example of the SRCREV change triggering a gitX bump is wrong, as both gitX and r0.X get incremented. Why this is happening is explained in bug 15729, which I copy here: > +gitX+ is indeed related to changes in the source code. > > r0.X is bumped each time the checksum of the do_package task of the > simple-hello-world-git recipe changes. This happens here: > https://git.openembedded.org/openembedded-core/tree/meta/classes-global/package.bbclass?id=235e6d49e5888ad04416219e10b6df91a738661a#n306 > > This line sets the value of PRAUTO and represents the number X found in > r0.X. It will in the end make it into EXTENDPRAUTO, which itself makes > to PKGR == r0.X. > > This line calls getPR(version, pkgarch, checksum). Between test case 5 > and 6, only the checksum changes. This checksum is the checksum of the > do_package task (gotten from get_do_package_hash() above). > > Now, let's dump what changed with regards to this task between two > consecutive runs, using the sigdata file in build/tmp/stamps/: > > ``` > [...] > Variable fetcher_hashes_dummyfunc value changed from '2650ad6714c3f3248abfe9d3daf1196f307ed494' to '4af682a50174f5deb0397847da97d7cdba4ad067' > ``` > > The last line shows that the value of fetcher_hashes_dummyfunc changed > from '2650ad6714c3f3248abfe9d3daf1196f307ed494' to > '4af682a50174f5deb0397847da97d7cdba4ad067'. Those are the commit hashes > in the git history of the simple-hello-world-git repository. > > Now you can see why this 0.X gets bumped, is because of the SRCREV change. Fix the example, and detail what gets changed and why.
