Richard Purdie 4c5d6edb0b bitbake: cooker/cookerdata: Rework the way the datastores are reset
As far as I could tell, the current code could result in some strange
situations where some data was set back to the original data store copy
but the multiconfig data was not restored. There are also some changes made
to the datastore which did not persist.

The data store was also being reset at every client reset, which seems
a little excessive if we can reset it to the original condition properly.

Move the __depends -> __base_depends rename into databuilder along with
the __bbclasstype change so these are saved in the original data.

Tweak the databuilder code to be clearer and easier to follow on which
copies are where, then save copies of all the mc datastores.

Finally, drop the cache invalidation upon reset for the base config
as we shouldn't need that now (oe-selftest -r tinfoil works with memory
resident bitbake which was the original reproducer requiring that change).

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: https://www.openembedded.org/

Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: https://docs.yoctoproject.org

Bitbake requires Python version 3.8 or newer.

Contributing

Please refer to https://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

Testing

Bitbake has a testsuite located in lib/bb/tests/ whichs aim to try and prevent regressions. You can run this with "bitbake-selftest". In particular the fetcher is well covered since it has so many corner cases. The datastore has many tests too. Testing with the testsuite is recommended before submitting patches, particularly to the fetcher and datastore. We also appreciate new test cases and may require them for more obscure issues.

To run the tests "zstd" and "git" must be installed. Git must be correctly configured, in particular the user.email and user.name values must be set.

The assumption is made that this testsuite is run from an initialized OpenEmbedded build environment (i.e. source oe-init-build-env is used). If this is not the case, run the testsuite as follows:

export PATH=$(pwd)/bin:$PATH
bin/bitbake-selftest
