    • Reorganize diff and add basic diff driver · 114f5a6c
      This is a significant reorganization of the diff code to break it
      into a set of more clearly distinct files and to document the new
      organization.  Hopefully this will make the diff code easier to
      understand and to extend.
      
      This adds a new `git_diff_driver` object that looks of diff driver
      information from the attributes and the config so that things like
      function content in diff headers can be provided.  The full driver
      spec is not implemented in the commit - this is focused on the
      reorganization of the code and putting the driver hooks in place.
      
      This also removes a few #includes from src/repository.h that were
      overbroad, but as a result required extra #includes in a variety
      of places since including src/repository.h no longer results in
      pulling in the whole world.

    • Make iterators use GIT_ITEROVER & smart advance · cee695ae
      1. internal iterators now return GIT_ITEROVER when you go past the
         last item in the iteration.
      2. git_iterator_advance will "advance" to the first item in the
         iteration if it is called immediately after creating the
         iterator, which allows a simpler idiom for basic iteration.
      3. if git_iterator_advance encounters an error reading data (e.g.
         a missing tree or an unreadable file), it returns the error
         but also attempts to advance past the invalid data to prevent
         an infinite loop.
      
      Updated all tests and internal usage of iterators to account for
      these new behaviors.

    • Add ~ expansion to global attributes and excludes · 7a5ee3dc
      This adds ~/ prefix expansion for the value of core.attributesfile
      and core.excludesfile, plus it fixes the fact that the attributes
      cache was holding on to the string data from the config for a long
      time (instead of making its own strdup) which could have caused a
      problem if the config was refreshed.  Adds a test for the new
      expansion capability.

    • Significant rename detection rewrite · a21cbb12
      This flips rename detection around so instead of creating a
      forward mapping from deltas to possible rename targets, instead
      it creates a reverse mapping, looking at possible targets and
      trying to find a source that they could have been renamed or
      copied from.  This is important because each output can only
      have a single source, but a given source could map to multiple
      outputs (in the form of COPIED records).
      
      Additionally, this makes a couple of tweaks to the public rename
      detection APIs, mostly renaming a couple of options that control
      the behavior to make more sense and to be more like core Git.
      
      I walked through the tests looking at the exact results and
      updated the expectations based on what I saw.  The new code is
      different from the old because it cannot give some nonsense
      results (like A was renamed to both B and C) which were part of
      the outputs previously.

    • Add more diff rename detection tests · 4742148d
      This adds a bunch more rename detection tests including checks
      vs the working directory, the new exact match options, some more
      whitespace variants, etc.
      
      This also adds a git_futils_writebuffer helper function and uses
      it in checkout.  This is mainly added because I wanted an easy
      way to write out a git_buf to disk inside my test code.

    • Fix issues with git_diff_find_similar · d958e37a
      There are a number of bugs in the rename code that only were
      obvious when I started testing it against large old repos with
      more complex patterns.  (The code to do that testing is not ready
      to merge with libgit2, but I do plan to add more thorough tests.)
      
      This contains a significant number of changes and also tweaks the
      public API slightly to make emulating core git easier.
      
      Most notably, this separates the GIT_DIFF_FIND_AND_BREAK_REWRITES
      flag into FIND_REWRITES (which adds a self-similarity score to
      every modified file) and BREAK_REWRITES (which splits the modified
      deltas into add/remove pairs in the diff list).  When you do a raw
      output of core git, rewrites show up as M090 or such, not at A and
      D output, so I wanted to be able to emulate that.
      
      Publicly, this also changes the flags to be uint16_t since we
      don't need values out of that range.
      
      Internally, this contains significant changes from a number of
      small bug fixes (like using the wrong side of the diff to decide
      if the object could be found in the ODB vs the workdir) to larger
      issues about which files can and should be compared and how the
      various edge cases of similarity scores should be treated.
      
      Honestly, I don't think this is the last update that will have to
      be made to this code, but I think this moves us closer to correct
      behavior and I tried to document the code so it would be easier
      to follow..
