(1) Only print out the names of the files and directories that got
actually deleted. Also do not mention that we are not removing
directories when the user did not ask us to do so with '-d'.
(2) Show ignore message for skipped untracked git repositories.
Consider the following repo layout:
test.git/
|-- tracked_dir/
| |-- some_tracked_file
| |-- some_untracked_file
|-- tracked_file
|-- untracked_file
|-- untracked_foo/
| |-- bar/
| | |-- bar.txt
| |-- emptydir/
| |-- frotz.git/
| |-- frotz.tx
|-- untracked_some.git/
|-- some.txt
Suppose the user issues 'git clean -fd' from the test.git directory.
When -d option is used and untracked directory 'foo' contains a
subdirectory 'frotz.git' that is managed by a different git repository
therefore it will not be removed.
$ git clean -fd
Removing tracked_dir/some_untracked_file
Removing untracked_file
Removing untracked_foo/
Removing untracked_some.git/
The message displayed to the user is slightly misleading. The foo/
directory has not been removed because of foo/frotz.git still exists.
On the other hand the subdirectories 'bar' and 'emptydir' have been
deleted but they're not mentioned anywhere. Also, untracked_some.git
has not been removed either.
This behaviour is the result of the way the deletion of untracked
directories are reported. In the current implementation they are
deleted recursively but only the name of the top most directory is
printed out. The calling function does not know about any
subdirectories that could not be removed during the recursion.
Improve the way the deleted directories are reported back to
the user:
(1) Create a recursive delete function 'remove_dirs' in builtin/clean.c
to run in both dry_run and delete modes with the delete logic as
follows:
(a) Check if the current directory to be deleted is an untracked
git repository. If it is and --force --force option is not set
do not touch this directory, print ignore message, set dir_gone
flag to false for the caller and return.
(b) Otherwise for each item in current directory:
(i) If current directory cannot be accessed, print warning,
set dir_gone flag to false and return.
(ii) If the item is a subdirectory recurse into it,
check for the returned value of the dir_gone flag.
If the subdirectory is gone, add the name of the deleted
directory to a list of successfully removed items 'dels'.
Else set the dir_gone flag as the current directory
cannot be removed because we have at least one subdirectory
hanging around.
(iii) If it is a file try to remove it. If success add the
file name to the 'dels' list, else print error and set
dir_gone flag to false.
(c) After we finished deleting all items in the current directory and
the dir_gone flag is still true, remove the directory itself.
If failed set the dir_gone flag to false.
(d) If the current directory cannot be deleted because the dir_gone flag
has been set to false, print out all the successfully deleted items
for this directory from the 'dels' list.
(e) We're done with the current directory, return.
(2) Modify the cmd_clean() function to:
(a) call the recursive delete function 'remove_dirs()' for each
topmost directory it wants to remove
(b) check for the returned value of dir_gone flag. If it's true
print the name of the directory as being removed.
Consider the output of the improved version:
$ git clean -fd
Removing tracked_dir/some_untracked_file
Removing untracked_file
Skipping repository untracked_foo/frotz.git
Removing untracked_foo/bar
Removing untracked_foo/emptydir
Skipping repository untracked_some.git/
Now it displays only the file and directory names that got actually
deleted and shows the name of the untracked git repositories it ignored.

"git" can mean anything, depending on your mood.
- random three-letter combination that is pronounceable, and not
actually used by any common UNIX command. The fact that it is a
mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the
dictionary of slang.
- "global information tracker": you're in a good mood, and it actually
works for you. Angels sing, and a light suddenly fills the room.

Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.
Git is an Open Source project covered by the GNU General Public License.
It was originally written by Linus Torvalds with help of a group of
hackers around the net. It is currently maintained by Junio C Hamano.
Please read the file INSTALL for installation instructions.
See Documentation/gittutorial.txt to get started, then see
Documentation/everyday.txt for a useful minimum set of commands, and
Documentation/git-commandname.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with "man gittutorial" or "git help tutorial", and the
documentation of each command with "man git-commandname" or "git help
commandname".
CVS users may also want to read Documentation/gitcvs-migration.txt
("man gitcvs-migration" or "git help cvs-migration" if git is
installed).
Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.
The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org (read
Documentation/SubmittingPatches for instructions on patch submission).
To subscribe to the list, send an email with just "subscribe git" in
the body to majordomo@vger.kernel.org. The mailing list archives are
available at http://marc.theaimsgroup.com/?l=git and other archival
sites.
The messages titled "A note from the maintainer", "What's in
git.git (stable)" and "What's cooking in git.git (topics)" and
the discussion following them on the mailing list give a good
reference for project status, development direction and
remaining tasks.
