Description of Issue

Filtering which is done here modifies dirnames which is not used for anything later.

My workaround is to modify generate_mtime_map function:

def generate_mtime_map(opts, path_map):
    Generate a dict of filename -> mtime
    file_map = {}
    for saltenv, path_list in six.iteritems(path_map):
        for path in path_list:
            log.error('Scanning path {0}'.format(path))
            for directory, dirnames, filenames in os.walk(path):
                for item in filenames:
                        file_path = os.path.join(directory, item)
                        # Don't walk any directories that match file_ignore_regex or glob
                        if is_file_ignored(opts, file_path):
                        file_map[file_path] = os.path.getmtime(file_path)
                    except (OSError, IOError):
                        # skip dangling symlinks
                            'Failed to get mtime on {0}, '
                            'dangling symlink ?'.format(file_path))
    return file_map

I was debugging it because I thought that it would increase performance in our deployment because we have file roots containing cloned git repositories and a lot of files in .git subdirectories but I cannot see significant improvement.


Add to master configuration:

  - '/\.svn($|/)'
  - '/\.git($|/)'

Steps to Reproduce Issue

Add log_level: debug to master configuration and restart it. There is no information about skipped files but because of that line there should be. After adding below fix they starts to appear.

                        if is_file_ignored(opts, file_path):

In my opinion significant performance could be achieved by replacing os.walk with something which will skip reading directory recursively if matched with file_ignore_regex.

This is a good catch, I've opened #49308 for this.

If you'd like to attempt a more efficient run at this function, we'd appreciate the pull request.
