Where a git url uses a tag instead of a full source revision, breakage can currently occur in builds. Issues include: * the revision being looked up in multiple tasks (fetch and unpack) * the risk a different revision may be obtained in those tasks * that some tasks may not be allowed to access the network * that a revision may not be consistent throughout a given build * rerunning a specific task may given inconsistent results To fix this, stop the workers from cleaning out the source revision store. This should only be done in the cooker itself (based on current policy). Also, where the code "sees" an upstream access, mark the recipe as not to be cached. The reparse re-triggers the upstream lookup by the server. Add a test to ensure that if get_srcrev isn't called, the user is told they're using a configuration that is known to break.

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:

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
Mailing list:
https://lists.openembedded.org/g/bitbake-devel

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.
