So, @nulltoken created a failing test case for checkout that
proved to be particularly daunting. If checkout is given only
a very limited strategy mask (e.g. just GIT_CHECKOUT_CREATE_MISSING)
then it is possible for typechange/rename modifications to leave it
unable to complete the request. That's okay, but the existing code
did not have enough information not to generate an error (at least
for tree/blob conflicts).
This led me to a significant reorganization of the code to handle
the failing case, but it has three benefits:
1. The test case is handled correctly (I think)
2. The new code should actually be much faster than the old code
since I decided to make checkout aware of diff list internals.
3. The progress value accuracy is hugely increased since I added
a fourth pass which calculates exactly what work needs to be
done before doing anything.
* Rework GIT_DIRREMOVAL values to GIT_RMDIR flags, allowing
combinations of flags
* Add GIT_RMDIR_EMPTY_PARENTS flag to remove parent dirs that
are left empty after removal
* Add GIT_MKDIR_VERIFY_DIR to give an error if item is a file,
not a dir (previously an EEXISTS error was ignored, even for
files) and enable this flag for git_futils_mkpath2file call
* Improve accuracy of error messages from git_futils_mkdir
Apparently git_remote_list() includes even remotes for which git_remote_load() would fail. Sorry @nulltoken, false alarm.
This reverts commit f358ec143c.
This fix makes libgit2 capable of parsing annotated tag objects that lack
the optional message/description field.
Previously, libgit2 treated this field as mandatory and raised a tag_error on
such tags. However, the message field is optional.
An example of such a tag is refs/tags/v2.6.16.31-rc1 in Linux:
$ git cat-file tag refs/tags/v2.6.16.31-rc1
object afaa018cefb6af63befef1df7d8febaae904434f
type commit
tag v2.6.16.31-rc1

This improves docs in some of the public header files, cleans
up and improves some of the example code, and fixes a couple
of pedantic warnings in places.
