In finalize() we save event handlers, register the ones relevant to the recipe being finalised, trigger events, and then restore the handlers so that one recipe's custom handlers (actually implemented within a class inherited by the recipe) do not affect other recipes. However, if an exception occurs during parsing, the saved handlers were not being restored. Use a try...finally block to ensure that the handlers are always restored. This issue became apparent since in OpenEmbedded-Core we have recently introduced a find_intercepts() handler for the bb.event.RecipePreFinalise event in image-postinst-intercepts.bbclass that images and old-style SDK recipes will end up inheriting. So far it doesn't seem that the the error has manifested itself in normal builds, but when parsing OE-Core recipes in the OE layer index it has: core-image-rt-* image recipes were parsed which in the default configuration raise SkipRecipe. The next non-image recipe that is parsed will trigger a real exception, because the find_intercepts() handler is still registered and gets fired, but in the context of the new recipe the POSTINST_INTERCEPTS_PATHS variable is not set, and the code in find_intercepts() is written with the reasonable assumption that that isn't possible given that the class itself sets a default, and thus it fails.

Bitbake
BitBake is a generic task execution engine that allows shell and Python tasks to be run efficiently and in parallel while working within complex inter-task dependency constraints. One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software stacks using a task-oriented approach.

Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: http://yoctoproject.org/documentation
Contributing
Please refer to http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded for guidelines on how to submit patches, just note that the latter documentation is intended for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org) but in general main guidelines apply. Once the commit(s) have been created, the way to send the patch is through git-send-email. For example, to send the last commit (HEAD) on current branch, type:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org
