[PATCH v21 00/19] Use ref transactions

List, Jun

Here is a resend of the first part of the ref transactions patches. This new series consists of the first 19 patches in the series and have been reviewed by mhagger. This series should be good to go now.

I will resend the remaining part of the series separately once I have addressed Michaels concerns.

Version 21:
 -- split the patch series in two. These are the first 19 patches that
    are now reviewed by mhagger.

Ronnie Sahlberg (19):
  refs.c: remove ref_transaction_rollback
  refs.c: ref_transaction_commit should not free the transaction
  refs.c: constify the sha arguments for
    ref_transaction_create|delete|update
  refs.c: allow passing NULL to ref_transaction_free
  refs.c: add a strbuf argument to ref_transaction_commit for error
    logging

  lockfile.c: make lock_file return a meaningful errno on failure
  refs.c: add an err argument to repack_without_refs
