diff-index --cc shows a 3-way diff between HEAD, index and working tree.

This implements a 3-way diff between the HEAD commit, the state in the
index, and the working directory.  This is like the n-way diff for a

Fix git-fsck-objects SIGSEGV/divide-by-zero

If you try to fsck a repository that isn't entirely empty, but that has no
inter-object references (ie all the objects are blobs, and don't refer to
anything else), git-fsck-objects currently fails.

This probably cannot happen in practice, but can be tested with something
like

git init-db
touch dummy
git add dummy
git fsck-objects

where the fsck will die by a divide-by-zero when it tries to look up the
references from the one object it found (hash_obj() will do a modulus by
refs_hash_size).

On some other archiectures (ppc, sparc) the divide-by-zero will go
unnoticed, and we'll instead SIGSEGV when we hit the "refs_hash[j]"
access.

So move the test that should protect against this from mark_reachable()
into lookup_object_refs(), which incidentally in the process also fixes
mark_reachable() itself (it used to not mark the one object that _was_
reachable, because it decided that it had no refs too early).

18 years agogit-fsck-objects: lacking default references should not be fatal

git-fsck-objects: lacking default references should not be fatal

The comment added says it all: if we have lost all references in a git
archive, git-fsck-objects should still work, so instead of dying it should
just notify the user about that condition.

This change was triggered by me just doing a "git-init-db" and then
populating that empty git archive with a pack/index file to look at it.
Having git-fsck-objects not work just because I didn't have any references
handy was rather irritating, since part of the reason for running
git-fsck-objects in the first place was to _find_ the missing references.

However, "--unreachable" really doesn't make sense in that situation, and
we want to turn it off to protect anybody who uses the old "git prune"
shell-script (rather than the modern built-in). The old pruning script
used to remove all objects that were reported as unreachable, and without
any refs, that obviously means everything - not worth it.

gitweb: Use git-diff-tree or git-diff patch output for blobdiff

This is second part of removing gitweb dependency on external
diff (used in git_diff_print).

Get rid of git_diff_print invocation in git_blobdiff, and use either
git-diff-tree (when both hash_base and hash_parent_base are provided)
patch format or git-diff patch format (when only hash and hash_parent
are provided) for output.

Supported URI schemes, and output formats:
* New URI scheme: both hash_base and hash_parent_base (trees-ish
  containing blobs versions we want to compare) are provided.
  Also either filename is provided, or hash (of blob) is provided
  (we try to find filename then).

  For this scheme we have copying and renames detection, mode changes,
  file types etc., and information extended diff header is correct.

* Old URI scheme: hash_parent_base is not provided, we use hash and
  hash_parent to directly compare blobs using git-diff. If no filename
  is given, blobs hashes are used in place of filenames.

  This scheme has always "blob" as file type, it cannot detect mode
  changes, and we rely on CGI parameters to provide name of the file.

Added git_to_hash subroutine, which transforms symbolic name or list
of symbolic name to hash or list of hashes using git-rev-parse.

To have "blob" instead of "unknown" (or "file" regardless of the type)
in "gitweb diff header" for legacy scheme, file_type function now
returns its argument if it is not octal string.

Added support for fake "2" status code in git_patchset_body. Such code
is generated by git_blobdiff in legacy scheme case.

ATTENTION: The order of arguments (operands) to git-diff is reversed
(sic!) to have correct diff in the legacy (no hash_parent_base) case.
$hash_parent, $hash ordering is commented out, as it gives reversed
patch (at least for git version 1.4.1.1) as compared to output in new
scheme and output of older gitweb version.
