This series is based on ref-transactions-reflog It is also available at https://github.com/rsahlberg/git/tree/ref-transactions-rename This series adds support to perform rename_ref as a single transaction for both deleting/re-creating the ref and updating the reflog. Since we no longer use rename() for the reflog changes we can now support renames even if the reflogs are symlinks. In order to make the delete-then-create fully atomic and also to ensure that at no point in time is the object unreferenced we add support to do deletes via the packed refs file to transaction_commit. For any refs that are to be deleted, we first copy these refs to the packed refs file. This allows us to immediately delete the loose ref files for those refs and still being able to cancel/rollback the transaction. Once all the changes are successfully updated we finally commit the packed refs file a second time at which stage all the refs-to-be-deleted all disappear in one atomic rename(). This allows us to perform transactions that delete multiple refs and have the delete appear as one atomic transaction to any external observer. Ronnie Sahlberg (4): refs.c: allow passing raw git_committer_info as email to _update_reflog refs.c: return error instead of dying when locking fails during transaction refs.c: use packed refs when deleting refs during a transaction refs.c: update rename_ref to use a transaction refs.c | 308 +++++++++++++++++++++++++++++++++--------------------- refs.h | 1 + t/t3200-branch.sh | 7 -- 3 files changed, 192 insertions(+), 124 deletions(-) -- 2.0.0.583.g402232d -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
