From: Jameson Miller <jamill@xxxxxxxxxxxxx>
This change teaches the status command more options to control which
ignored files are reported independently of the which untracked files
are reported by allowing the `--ignored` option to take additional
arguments. Currently, the shown ignored files are linked to how
untracked files are reported. Both ignored and untracked files are
controlled by arguments to `--untracked-files` option. This makes it
impossible to show all untracked files individually, but show ignored
"files and directories" (that is, ignored directories are shown as 1
entry, instead of having all contents shown).
Our application (Visual Studio) has a specific set of requirements
about how it wants untracked / ignored files reported by git status.
It requires all untracked files listed individually. It would like
ignored files and directories that explicity match an exclude pattern
listed. If an ignored directory matches an exclude pattern, then the
path of the directory should be returned. If a directory does not
match an exclude pattern, but all of its contents are ignored, then we
want the contained files reported instead of the directory.
The reason for controlling these behaviors separately is that there
can be a significant performance impact to scanning the contents of
excluded directories. Additionally, knowing whether a directory
explicitly matches an exclude pattern can help the application make
decisions about how to handle the directory. If an ignored directory
itself matches an exclude pattern, then the application will know that
any files underneath the directory must be ignored as well.
As a more concrete example, on Windows, Visual Studio creates a bin/
and obj/ directory inside of the project where it writes all .obj and
binary build output files. Normal usage is to explicitly ignore these
2 directory names in the .gitignore file (rather than or in addition
to *.obj). We just want to see the "bin/" and "obj/" paths regardless
of which "--untracked-files" flag is passed in. Additionally, if we
know the bin/ and obj/ directories are ignored, then we can ignore any
files changes we notice underneath these paths, as we know they do not
affect the output of stats.
