This is to allow new builds to occur when SRC_URI changes.<br /> <br /> b) The version field seen by the package manager needs to increase in for changes in the metadata (which comes from the PR Service) in a way that sorts correctly and allows incremental package upgrades<br /> <br /> c) The version field seen by the package manager needs to increase in for changes in SRC_URI in a way that sorts correctly and allows incremental package upgrades<br /> <br /> <br /> To make this happen, several things happen:<br /> <br /> a) In scm based recipes, SRCPV is injected into PV in the correct place. <br /> <br /> b) SRCPV contains a set of numbers that increase for each new revision, one per SCM source contained in SRC_URI.<br /> <br /> c) If automatic revisions are enabled, SRCPV starts with the placeholder string &quot;AUTOINC+&quot;<br /> <br /> d) The AUTOINC string is replaced with the correct version number during do_package and the PR service ensures these numbers increment.<br /> <br /> e) An automatic incrementing number from the PR Service is appended to PKGR through the AUTOPR variable.<br /> <br /> f) AUTOPR is only set during do_package when the packages are generated</div>
