Johannes Schneider 0a5c5430c5 bitbake: bitbake-setup: init: suggest removing a partially initialized top-dir
In cases where the first call to 'init' failed or was aborted before
creating the 'build/init-build-env' has been created, a user can get
stuck: a second call to init aborts, suggesting 'status' or 'update'
but these to refuse because the --build-dir is not valid.

Guide the user by adding a suggestion to start over from scratch.

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 our contributor guide here: https://docs.yoctoproject.org/contributor-guide/
for full details on how to submit changes.

As a quick guide, patches should be sent to bitbake-devel@lists.openembedded.org
The git command to do that would be:

    git send-email -M -1 --to bitbake-devel@lists.openembedded.org

If you're sending a patch related to the BitBake manual, make sure you copy
the Yocto Project documentation mailing list:

    git send-email -M -1 --to bitbake-devel@lists.openembedded.org --cc docs@lists.yoctoproject.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.

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

The testsuite can alternatively be executed using pytest, e.g. obtained from PyPI (in this
case, the PATH is configured automatically):

    pytest
