Hi, This series builds on the previous series : ref-transaction-reflog as applied to master. This series has been sent to the list before[1] This series can also be found at github[2] as well as googlesource[3]. This series converts ref rename to use a transaction. This addesses several issues in the old implementation, such as colliding renames might overwrite someone elses reflog, and it makes the rename atomic. As part of the series we also move changes that cover multiple refs to happen as an atomic transaction/rename to the pacekd refs file. This makes it possible to have both the rename case (one deleted ref + one created ref) as well as any operation that updates multiple refs to become one atomic rename() applied to the packed refs file. Thus all such changes are now also atomic to all external observers. Thanks, Stefan Version 2: - Changed to not use potentially iterators to copy the reflog entries one by one. Instead adding two new functions. One to read an existing reflog as one big blob, and a second function to, in a transaction, write a new complete reflog from said blob. The idea is that each future reflog backend will provide optimized versions for these "read whole reflog" "write whole reflog" functions. Version 3: - Rename and redo the API for updating a whole reflog in one single operation to transaction_rename_reflog() Version 4: * As Ronnie announced to change employers soon, he'll have only limited time to work on git in the near future. As this is a rather large patch series, he is handing this work over to me. That's why I'm sending the patches this time.
