Release

5.7.0

Description

Features

  • Update reftable storage repo layout. The change c217d33, "Documentation/technical/reftable: improve repo layout" defines a new repository layout, which was agreed with the git-core mailing list. It addresses the following problems:
    • old git clients will not recognize reftable-based repositories, and look at encompassing directories.
    •  Poorly written tools might write directly into .git/refs/heads/BRANCH.
    •  Since we consider JGit reftable as experimental (git-core doesn't support it yet), we have no backward compatibility. If you created a repository with reftable between mid-Nov 2019 and now, you can do the following to convert:
      • mv .git/refs .git/reftable/tables.list

        git config core.repositoryformatversion 1

        git config extensions.refStorage reftable
  • Documentation/technical/reftable: improve repo layout. Previously, the list of tables was in .git/refs. This makes    repo detection fail in older clients, which is undesirable. This is proposal was discussed and approved on the git@vger list at https://lore.kernel.org/git/CAFQ2z_PvKiz==GyS6J1H1uG0FRPL86JvDj+LjX1We4-yCSVQ+g@mail.gmail.com. For backward compatibility, JGit could detect a file under .git/refs and use it as a reftable list.
