Richard Purdie 2946c56b23 bitbake: bitbake: siggen/runqueue: Switch to using RECIPE_SIGGEN_INFO feature for signature dumping
Now that we have cache support for the taskdep/gendep/lookupcache data,
we can switch to use that cooker feature and skip the secondary reparse to
write the sig files. This does make the initial parse longer but means the
secondary one isn't needed.

At present parsing with the larger cache isn't optimal but we have plans
in place which will make this faster than the current reparse code being
removed here.

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

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
