I was blinded by the primary reason of your patch being "be more careful and defer reporting a removal until we know everything in a directory did get removed and managed to remove the directory", and did not realize this "noise removal". Perhaps add Also do not mention that we are not removing directories when the user did not ask us to do so with '-d'. or something to the description?

What do you think? Agree, the output looks much neater printed like that.

I wonder whether it's possible to make the output more consistent, as in: 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 or similar. What do you think?

[PATCH v4] git-clean: Display more accurate delete messages
(1) Only print out the names of the files and directories that got actually deleted. (2) Show warning message for ignored 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 warning: ignoring untracked git repository untracked_foo/frotz.git Removing untracked_foo/bar Removing untracked_foo/emptydir warning: ignoring untracked git repository untracked_some.git/ Now it displays only the file and directory names that got actually deleted and shows warnings about ignored untracked git repositories.
