linux-yocto: improve checkout error handling and reporting
The typical workflow for linux-yocto simply uses a remote
upstream repository (Whether it is mirrored or not), and in this
case there are no issues with consistency in the format of the
resository that is unpacked into the WORKDIR.
When working with a local linux-yocto repository for kernel
development the remote vs local branches is not always consistent
between repositories.
The suggested/documented workflow has always been to use a
bare clone of linux-yocto, and use a second working tree repository
for development. Changes flow from the working tree to the bare
clone and then into the working directory for build. A common
mistake that happens with this workflow is that the non-bare,
working repository is used instead of the bare clone version.
If a non-bare repository is reference by the SRC_URI, then the
branches that are fetched into WORKDIR are not consitent. If the
MACHINE and META branches are not present, cryptic build errors
will result.
To solve this problem, the checkout code has been changed in
several ways:
- works with a newly proposed 'bareclone' option to bitbake
- detects if a bareclone is present in WORKDIR or not and
adjustst the checkout accordingly.
- if a non-bare clone is detected, machine and meta branches
are checked. If they are not present, or can't be created
a clear error message is produced
- instead of manipulating the refs directly in the git tree,
local tracking branches are (quietly) created for remote
branches. Enabling a better workflow in the WORKDIR kernel
repository.
This has been tested with linux-yocto remote upstreams, local
bare and non-bare respositories. All builds succeed or fail
with clear error messages.
