The current approach to remote datastores used in tinfoil is breaking. For example, adding a devupstream extension to a recipe with a git upstream, making it the preferred version and then running "devtool modify" on it causes get_srcrev() circular dependency issues. The problem is the override handling in the datastore is broken. This gets broken since remotedata:recieve_datastore() sets d.dict but doesn't update d.overridedata (or d.inchistory or d.varhistory). We could play whack-a-mole but the current implementation seems to be flawed to me. It also doesn't cover, or only partially covers some datastore operations and each needs new dedicated command API. Instead, step back and reimplement the way the datastore connector works. With this change, the datastore is either remote or local but the data is not spread on two sides of the connection. All the API is proxied over the connection by a single function for the datastore (and two to support variable history and include history). This code does not support using the datastore as a parameter to any data store functions. We did have one case of that but its just bad code and can be replaced. The result is something which is much simpler and less invasive to the datastore code itself, meaning its behaviour should be much more consistent. The existing tests for the remote data no longer make any sense and are removed. The one bug this code would have is if key/value pairs are returned over the IPC and those values contained a DataSmart object since we don't recurse into return values to find such things. Nothing appears to do that currently so lets worry about it if its ever an issue. This change should simplfy a ton of other issues and avoid a ton of other bugs so is a huge net gain. Tested with bitbake's and OE's selftests. (Bitbake rev: 85e03a64dd0a4ebe71009ec4bdf4192c04a9786e) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
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.
For information about Bitbake, see the OpenEmbedded website: http://www.openembedded.org/
Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: http://yoctoproject.org/documentation

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
