This adds a `git_diff_patch_line_stats()` API that gets the total
number of adds, deletes, and context lines in a patch. This will
make it a little easier to emulate `git diff --stat` and the like.
Right now, this relies on generating the `git_diff_patch` object,
which is a pretty heavyweight way to get stat information. At
some future point, it would probably be nice to be able to get
this information without allocating the entire `git_diff_patch`,
but that's a much larger project.
This is a convenience function to get the branch name of a given
ref. The returned branch name is compatible with the name that can
be supplied e.g. to git_branch_lookup(). That is, the prefixes
"refs/heads" or "refs/remotes" are omitted.
Also added a new test for testing the new function.
This adds a new external API git_tree_entry_cmp and a new internal
API git_tree_entry_icmp for sorting tree entries. The case
insensitive one is internal only because general users should
never be seeing case-insensitively sorted trees.
This adds an option to checkout a la the diff option to turn off
fnmatch evaluation for pathspec entries. This can be useful to
make sure your "pattern" in really interpretted as an exact file
match only.
All the ODB backends have a specific refresh interface. When reading an
object, first we attempt every single backend: if the read fails, then
we refresh all the backends and retry the read one more time to see if
the object has appeared.
This moves the implementation of these two APIs into common code
that will be shared between the two. Also, this adds tests for
the `git_diff_blob_to_buffer` API. Lastly, this adds some extra
`const` to a few places that can use it.
This moves a lot of the detailed checkout documentation into a new
file (docs/checkout-internals.md) and simplifies the public docs
for the checkout API.
This adds a new API to the submodule interface that just returns
where information about the submodule was found (e.g. config file
only or in the HEAD, index, or working directory).
Also, the old "refresh" call was potentially keeping some stale
submodule data around, so this simplfies that code and literally
discards the old cache, then reallocates.
Make checkout update entries in the index for all files that are
updated and/or removed, unless flag GIT_CHECKOUT_DONT_UPDATE_INDEX
is given. To do this, iterators were extended to allow a little
more introspection into the index being iterated over, etc.
This flips checkout back to be driven off the changes between
the baseline and the target trees. This reinstates the complex
code for tracking the contents of the working directory, but
overall, I think the resulting logic is easier to follow.
I've tried to map out the detailed behaviors of checkout and make
sure that we're handling the various cases correctly, along with
providing options to allow us to emulate "git checkout" and "git
checkout-index" with the various flags. I've thrown away flags
in the checkout API that seemed like clutter and added some new
ones. Also, I've converted the conflict callback to a general
notification callback so we can emulate "git checkout" output and
display "dirty" files.
As of this commit, the new behavior is not working 100% but some
of that is probably baked into tests that are not testing the
right thing. This is a decent snapshot point, I think, along the
way to getting the update done.
