The 'update-ref' command is used to update refs using transactions. The
command allows users to also utilize a '--stdin' mode to provide a
batch of sub-commands which can be processed in a transaction.
Currently, the sub-commands involve {verify, delete, create, update}
and they allow users to work with regular refs in the repository. To
work with symrefs, users only have the option of using
'git-symbolic-ref', which doesn't provide transaction support to the
users eventhough it uses the same behind the hood.
Recently, we modified the reference backend to add symref support,
following which, 'git-symbolic-ref' also uses the transaction backend.
But, it doesn't expose this to the user. To allow users to work with
symrefs via transaction, this series adds support for new sub-commands
{symrer-verify, symref-delete, symref-create, symref-update} to the
'--stdin' mode of update-ref. These complement the existing
sub-commands.
The patches 1, 5 fix small issues in the reference backends. The other
patches 2, 3, 4 & 6, each add one of the new sub-commands.
The series is based off master, with 'kn/ref-transaction-symref' merged
in.
