[PATCH v3 00/32] object-store: lookup_commit

This continues the elimination of global variables in the object store and teaches lookup_commit[_reference] and alike to handle a_repository.

This is also available as https://github.com/stefanbeller/git/tree/object-store-lookup-commit or applies on top of 02f70d63027 (Merge branch 'sb/object-store-grafts' into next, 2018-06-28).

Picking a base for this one is really hard, as nearly all series currently cooking or in flight collide with it on one or two lines. (lookup_* is used heavily, who would have thought?); I really needed 'sb/object-store-grafts' to build on; and there is only one other series before that in current next, which this series would have conflicted with, if not based on top of it.

In "The state of the object store series" [1], this was tentatively named "sb/object-store-lookup".

Thanks, Stefan

v2 https://public-inbox.org/git/20180613230522.55335-1-sbeller@google.com/
* removed mentions of cooci patches
* added forward declaration of commit buffer slabs.
* dropped 3 patches that add the repository to lookup_unkonwn_object,
  parse_commit and parse_commit_gently, but were not converting those
  functions. We'll convert these in the next series, as this series is
  growing big already.
* This series can be found as branch 'object-store-lookup-commit' on github,
  it applies on top of nd/commit-util-to-slab merged with sb/object-store-grafts

v1, https://public-inbox.org/git/20180530004810.30076-1-sbeller@google.com/

This applies on the merge of nd/commit-util-to-slab and sb/object-store-grafts, and is available at http://github.com/stefanbeller/ as branch object-store-lookup-commit as the merge has some merge conflicts as well as syntactical conflicts (upload-pack.c and fetch-pack.c introduce new calls of functions that would want to take a repository struct in the object-store-grafts series)

As layed out in https://public-inbox.org/git/20180517225154.9200-1-sbeller@google.com/
this is getting close to finishing the set of object store series though the last
unfinished part of this RFC hints at new work on the plate:
* To give this series a nice polish, we'd want to convert parse_commit, too.
  But that requires the conversion of the new commit graph. Maybe we need
  to split this series into 2. 
* Once this is in good shape we can talk about converting parts of the revision
  walking code,
* which then can be used by the submodule code as the end goal for the
  object store series.

Thanks, Stefan
