Subject: [PATCH 00/10] Resending sb/submodule-recursive-fetch-gets-the-tip
Date: Thu, 25 Oct 2018 16:32:21 -0700	[thread overview]
Message-ID: <20181025233231.102245-1-sbeller@google.com> (raw)

Thanks Jonathan for your thoughtful comments,
here is the product of the discussion:
* I split up the patch to fetch in the worktree to be 2 patches,
  each giving motivation on its own.
* the last patch is vastly simplified in code, but takes an extra test
* in [1], you remark "commits" ought not to be a pointer, but I decided against
  that, as we keep the pointed-at value around for the same time span (until
  we're done with that submodule) and we don't need to copy over the pointed-at
  value into the new struct.

[1] https://public-inbox.org/git/20181018003954.139498-1-jonathantanmy@google.com/

This is still based on ao/submodule-wo-gitmodules-checked-out.

    -    submodule: fetch in submodules git directory instead of in worktree
    +    submodule: migrate get_next_submodule to use repository structs
     
    -    This patch started as a refactoring to make 'get_next_submodule' more
    -    readable, but upon doing so, I realized that "git fetch" of the submodule
    -    actually doesn't need to be run in the submodules worktree. So let's run
    -    it in its git dir instead.
    +    We used to recurse into submodules, even if they were broken having
    +    only an objects directory. The child process executed in the submodule
    +    would fail though if the submodule was broken.
     
    -    That should pave the way towards fetching submodules that are currently
    -    not checked out.
    -
    -    This patch leaks the cp->dir in get_next_submodule, as any further
    -    callback in run_processes_parallel doesn't have access to the child
    -    process any more. In an early iteration of this patch, the function
    -    get_submodule_repo_for directly returned the string containing the
    -    git directory, which would be a better design choice for this patch.
    -
    -    However the next patch both fixes the memory leak of cp->dir and also has
    -    a use case for using the full repository handle of the submodule, so
    -    it makes sense to introduce the get_submodule_repo_for here already.
    +    This patch tightens the check upfront, such that we do not need
    +    to spawn a child process to find out if the submodule is broken.
