the full sha1 of the pre- and post-images.

However, if the diff is generated with --full-index (but not

If we don't have the postimage blob, though, we try to look
at the actual fragments, of which there are none, and get a
segfault. This patch checks explicitly for that case and

config: treat non-existent config files as empty

The git_config() function signals error by returning -1 in
two instances:

  1. An actual error occurs in opening a config file (parse
     errors cause an immediate die).

  2. Of the three possible config files, none was found.

However, this second case is often not an error at all; it
simply means that the user has no configuration (they are
outside a repo, and they have no ~/.gitconfig file). This
can lead to confusing errors, such as when the bash
completion calls "git config --list" outside of a repo. If
the user has a ~/.gitconfig, the command completes
succesfully; if they do not, it complains to stderr.

This patch allows callers of git_config to distinguish
between the two cases. Error is signaled by -1, and
otherwise the return value is the number of files parsed.
This means that the traditional "git_config(...) < 0" check
for error should work, but callers who want to know whether
we parsed any files or not can still do so.

git-gui: correct assignment of work-tree

git-gui currently uses its own logic to determine the work-tree setting
but 'git rev-parse --toplevel' directly returns git's work-tree value
by calling get_git_work_tree() and is therefore always correct.

This fixes an inability to handle some repository configurations. In
particular where .git is a file containing a path to the real directory
(a cross-platform symbolic link).
To continue to support older versions than 1.7.0, setting the work-tree
by normalizing the --show-cdup value is more reliable as git-dir might be
outside the work-tree entirely.
