[PATCH v2 0/8] log --remerge-diff

[Thomas Rast <tr@thomasrast.ch>]

This is the second iteration of

  http://thread.gmane.org/gmane.comp.version-control.git/241565

Changes since the last version:

* Dropped patches 4 and 5 (log --merge-bases)

* Implemented the "full-file conflict" scheme explained in the
  previous cover letter: if the conflicted version is lacking one
  stage of a file, it synthesizes a conflict file of the form

    <<<<<<<
    =======
    content of the stage that exists
    >>>>>>>

  (or the other way around if stage3 is missing).  This occurs at
  least with delete/modify conflicts.

* Implemented some basic handling of directory/file conflicts.  I'm
  not completely happy yet -- see the NEEDSWORK comments -- but at
  least it gives consistent input to the diffing stage.

  This required access to the dir hash, so there's a new patch 7 that
  makes this possible.

Patches 1-6 (used to be 1-3 and 6-8) are unchanged.


Thomas Rast (8):
  merge-recursive: remove dead conditional in update_stages()
  merge-recursive: internal flag to avoid touching the worktree
  merge-recursive: -Xindex-only to leave worktree unchanged
  combine-diff: do not pass revs->dense_combined_merges redundantly
  Fold all merge diff variants into an enum
  merge-recursive: allow storing conflict hunks in index
  name-hash: allow dir hashing even when !ignore_case
  log --remerge-diff: show what the conflict resolution changed
