      submodule clone: use repo_config_set() · 347b232b
      Duy Nguyen authored
      Avoid direct access to $SUBMODULE/config and do it through
      repo_config_set() instead. Note that repo_submodule_init() cannot be
      used because this early in the submodule initialization process, we
      may fail to get and parse .gitmodules with submodule_from_path().

      submodule deinit: support multiple worktrees · 17238436
      Duy Nguyen authored
      This is the reverse of 'init' or 'add', config from superproject is
      removed from config.worktree (or just config in standard single
      worktree setup)

      submodule sync: support multiple worktrees · d8e680cb
      Duy Nguyen authored
      Both submodule.*.url and remote.*.url are stored per-worktree. If the
      remote key is already there (and shared) it will be overriden. We don't
      want to change the shared value because that might affect other
      worktrees.

      submodule update: add tests for multiple worktrees · da0740ea
      Duy Nguyen authored
      There are no changes needed for 'submodule update'. The clones will be
      per-worktree (because $GIT_DIR/modules is already per-worktree) and all
      the support is already in place. Add a test to make sure it actually
      works.

      submodule init: support multiple worktrees · 3d3144ec
      Duy Nguyen authored
      The entire submodule section in the superproject will be per-worktree
      and written to $GIT_DIR/config.worktree.
      
      The behavior when you only have one worktree (and not enabled
      extensions.worktreeConfig) is the same as before, everything is still
      written in $GIT_DIR/config

      config: add --move-to[-regexp] · 790bacd8
      Duy Nguyen authored
      This option can be used to move one or multiple variables from one
      place to another, e.g. to move some aliases from repo config to user
      config, or from repo config to per-worktree config.
      
      This will be useful for moving config variables around, especially when
      enabling or disabling extensions.worktreeConfig (see the update in
      git-worktree.txt for a real example).
      
      The implementation is definitely not the best. We could lock both
      source and destination before the move, and perhaps edit these files
      just once instead of once per key. But it adds a lot more complication
      to config write code. Let's stay with something simple. We can
      optimize it later.

      config: factor out set_config_source_file() · 663c797b
      Duy Nguyen authored
      In the next patch, "config" is taught to move some config variables
      from one file to another. We need to specify two locations, source and
      destination, and the plan is reusing the same --global/--local/...
      option. Factor this code out for reuse later.

      config: use OPT_FILENAME() · 66445664
      Duy Nguyen authored
      Do not handle prefix directly. It's simpler to use OPT_FILENAME()
      instead. The othe reason for doing this is because this code (where
      the deleted code is) will be factored out and called when "prefix" is
      not available.

      config.c: add repo_config_set_worktree_gently() · 5e3dc992
      Duy Nguyen authored
      This is C equivalent of "git config --set --worktree". In other words,
      it will
      
      - write to $GIT_DIR/config in single-worktree setup
      
      - write to $GIT_COMMON_DIR/worktrees/<x>/config.worktree or
        $GIT_COMMON_DIR/config.worktree (for main worktree)
        if extensions.worktreeConfig is enabled
      
      - return error in multiple-worktree setup if extensions.worktreeConfig
        is not enabled.
      
      While at there, also add repo_config_set*() for writing to
      $GIT_COMMON_DIR/config.
      
      Note, since git_config_set_multivar_in_file_gently() only invalidates
      the config set of the_repository, anybody who uses these functions on
      submodules must do additional invalidation if needed.

      "git config --worktree" can write to the write file whether
      extensions.worktreeConfig is enabled or not. In order to do the same
      using config API, we need to determine the right file to write to. Add
      this function for that purpose. This is the basis for the coming

      config.c: avoid git_path() in do_git_config_sequence() · 7d8693d7
      Duy Nguyen authored
      This function has both $GIT_COMMON_DIR and $GIT_DIR in "opts". Use it
      to construct config.worktree path instead because git_pathdup() is
      tied to the current worktree, but the given $GIT_DIR could be from
      another one.

      doc: outline how submodules work with multi worktrees · 07a84fe5
      Duy Nguyen authored
      This lays out the very first step of making multiple worktrees and
      submodules work together. No actual changes are here. And real changes
      are not even in the very next patches since they are cleanup and
      preparation patches.
      
      When a submodule is added to a superproject, the superproject's config
      file records info related to the submodule in its config file. The
      submodule's config file also has core.worktree to point back to the
      submodule worktree's location.
      
      Since config files are shared without extensions.worktreeConfig, adding
      a secondary superproject or submodule worktree will run into trouble [1].
      The problem could be solved with extensions.worktreeConfig and we keep
      per-worktree config in config.worktree files, both at superproject
      (submodule.*.*) and submodule (core.worktree) levels.
      
      The whole directory layout would look like this. This shows how
      multiple worktrees of a submodule or a supermodule are organized:
      
        .git/
          config                           contains shared submodule.*
          config.worktree                  contains submodule.sub1.*
                                           for the main worktree
          worktrees/
            super1/                   (1)
              config.worktree              submodule.sub1.* for super1
              modules/
                sub1/                 (2)
                  config.worktree          contains core.worktree
                  objects/            (3)
                  worktrees/          (4)
                    wt1/
                    wt2/
            super2/                   (5)
              config.worktree              submodule.sub1.* for super2
              modules
                sub1/                 (6)
                  config.worktree          contains core.worktree
                  objects/            (7)
        super1/
          .git                     -> (1)
          sub1/
            .git                   -> (2)
          sub1-wt1/
            .git                   -> (4)/wt1
          sub1-wt2/
            .git                   -> (4)/wt2
        super2/
          .git                     -> (5)
          sub1/
            .git                   -> (6)
      
      This directory layout works, but not optimal. Submodule clones (inside
      the "modules" directory) are per-worktree. If you have two
      superproject worktrees that contain a submodule, you need space for
      _two_ clones, e.g. the object databases (3) and (7) are almost
      identical, but they are still duplicated.
      
      This is definitely not elegant. The tentative plan is to move the
      clones to a common tree like below. This is however just an idea and
      not implemented in this series.
      
        .git/
          config                           contains shared submodule.*
          objects/
          common/
            modules/
              sub1/                   (0)
                objects/              (shared)
                worktrees/
                  super1/             (2)
                  super1-wt1/         (4)/wt1
                  super1-wt2/         (4)/wt2
                  super2/             (6)
      	  common/
      	    modules/
      	      nested-sub/...
          worktrees/
            super1/                   (1)
              config.worktree              submodule.sub1.* for super1
            super2/                   (5)
              config.worktree              submodule.sub1.* for super2
      
      The subtree (0) is shared across all worktrees because it's inside
      "common/" directory. Once we keep the clone in a common place like
      this, the submodule's worktree can be created and managed with
      git-worktree[1].
      
      Another good point about this approach is we could finally safely
      allow "git worktree remove" to work with submodules. With current
      solution, removing $GIT_COMMON_DIR/worktrees/X directory means also
      removing potentially precious clones inside the "modules" subdir.
      
      But whether we can do this depends on:
      
      - if we need separate ref namespace for submodule on each worktree.
        Use cases that can share ref namespace will work best.
      
      - how does submodule's worktrees interact these worktrees
      
      - handling nested submodules can get very messy (or not?)
      
      This series does not attempt to implement subtree (0) at all. Once we
      get submodules and worktrees work well together (even wasteful of disk
      space), we can start thinking about absorbing clones back to common/
      
      [1] It's milder for secondary submodule worktree because core.worktree
          will not be shared (core.worktree by default is only visible to
          the main worktree). But then the second worktree cannot have its
          own core.worktree.

      missing blobs we will need, instead of waiting for the on-demand
      machinery to discover them one by one.  Aim to achieve better
      performance by batching the request for these promised blobs.

      "git submodule" learns "set-branch" subcommand that allows the
      submodule.*.branch settings to be modified.

        submodule: teach set-branch subcommand
        submodule--helper: teach config subcommand --unset
