Merge branch 'mh/ref-transaction'
Update "update-ref --stdin [-z]" and then introduce a transactional support for (multi-)reference updates. * mh/ref-transaction: (27 commits) ref_transaction_commit(): work with transaction->updates in place struct ref_update: add a type field struct ref_update: add a lock field ref_transaction_commit(): simplify code using temporary variables struct ref_update: store refname as a FLEX_ARRAY struct ref_update: rename field "ref_name" to "refname" refs: remove API function update_refs() update-ref --stdin: reimplement using reference transactions refs: add a concept of a reference transaction update-ref --stdin: harmonize error messages update-ref --stdin: improve the error message for unexpected EOF t1400: test one mistake at a time update-ref --stdin -z: deprecate interpreting the empty string as zeros update-ref.c: extract a new function, parse_next_sha1() t1400: test that stdin -z update treats empty <newvalue> as zeros update-ref --stdin: simplify error messages for missing oldvalues update-ref --stdin: make error messages more consistent update-ref --stdin: improve error messages for invalid values update-ref.c: extract a new function, parse_refname() parse_cmd_verify(): copy old_sha1 instead of evaluating <oldvalue> twice ...
