If you build virtual/kernel, then change PREFERRED_PROVIDER_virtual/kernel from say "linux-yocto" to "linux-yocto-dev", you see errors from the sysroot about overlapping files. The automatic uninstall logic doesn't trigger since the other recipes is still technically parsed/buildable.
What we can do is look at the value of PREFERRED_PROVIDER_virtual/X and raise SkipRecipe (skip parsing) if it provides this thing and its not selected. We skip cases no preferred provider is set, or the value is in MULTI_PROVIDER_WHITELIST.We also inform the user if they try to build something which conflicts with the configuration: $ bitbake linux-yocto-tiny ERROR: Nothing PROVIDES 'linux-yocto-tiny' ERROR: linux-yocto-tiny was skipped: PREFERRED_PROVIDER_virtual/kernel set to linux-yocto, not linux-yocto-tiny [YOCTO #4102] Signed-off-by: Richard Purdie <[email protected]> diff --git a/meta/classes/base.bbclass b/meta/classes/base.bbclass index 44ca781..b8f2aea 100644 --- a/meta/classes/base.bbclass +++ b/meta/classes/base.bbclass @@ -204,7 +204,7 @@ def buildcfg_neededvars(d): bb.fatal('The following variable(s) were not set: %s\nPlease set them directly, or choose a MACHINE or DISTRO that sets them.' % ', '.join(pesteruser)) addhandler base_eventhandler -base_eventhandler[eventmask] = "bb.event.ConfigParsed bb.event.BuildStarted bb.event.RecipePreFinalise bb.runqueue.sceneQueueComplete" +base_eventhandler[eventmask] = "bb.event.ConfigParsed bb.event.BuildStarted bb.event.RecipePreFinalise bb.runqueue.sceneQueueComplete bb.event.RecipeParsed" python base_eventhandler() { import bb.runqueue @@ -257,6 +257,25 @@ python base_eventhandler() { bb.debug(1, "Executing SceneQueue Completion commands: %s" % "\n".join(cmds)) bb.build.exec_func("completion_function", e.data) os.remove(completions) + + if isinstance(e, bb.event.RecipeParsed): + # + # If we have multiple providers of virtual/X and a PREFERRED_PROVIDER_virtual/X is set + # skip parsing for all the other providers which will mean they get uninstalled from the + # sysroot since they're now "unreachable".
