[PATCH] status: do not get confused by submodules in excluded directories

[PATCH] status: do not get confused by submodules in excluded directories

[Johannes Schindelin]

We meticulously pass the `exclude` flag to the `treat_directory()`
function so that we can indicate that files in it are excluded rather
than untracked when recursing.

But we did not yet treat submodules the same way.

... "because of that, we ended up showing <<what incorrect result in
what situation>>" would be a nice thing to have here, so that it can
be copied to the release notes for the bugfix.  

How far back a release do we want to make this fix applicable?  It
seems that it applies cleanly to maint-2.13 without breaking from my
quick test, so that is probably where I'll queue this, even though
we may no longer issue further maintenance releases on that track.

Any comment from submodule folks?

Sorry that I didn't notice this was left unattended by anybody til
now.  Will queue while waiting for those who are into submodules to
respond.

Thanks.

Yes I agree that would be nice here. It was not immediately obvious that
this only applies when using both flags: -u and --ignored.

Seems to be a corner that not many people are using. At first I thought
a plain 'git status' would show that behavior...

How about:

Because of that, we ended up showing the submodule as untracked and its
content as ignored files when using the --ignored and -u flags with git
status.

? But maybe Dscho also has some more information to add about his
situation?

He has... as part of v2, a substantially more detailed commit message will

Could this use test_commit -C tracked/submodule initial?

Yes! Thanks. For some reason, I did not even think that test_commit would
accept the -C option.

[PATCH v2 0/1] Do not handle submodules in excluded directories as untracked

[Johannes Schindelin]

Anything in an excluded directory should be ignored, not only files and
directories but also submodules.

Changes since v1:

- simplified the test case, as suggested by Kevin

- added explicit output to the commit message to demonstrate what is fixed

[PATCH v2 1/1] status: do not get confused by submodules in excluded directories

[Johannes Schindelin]

We meticulously pass the `exclude` flag to the `treat_directory()`
function so that we can indicate that files in it are excluded rather
than untracked when recursing.

But we did not yet treat submodules the same way.

Because of that, `git status --ignored --untracked` with a submodule
`submodule` in a gitignored `tracked/` would show the submodule in the
"Untracked files" section, e.g.

	On branch master
	Untracked files:
	  (use "git add <file>..." to include in what will be committed)

		tracked/submodule/

	Ignored files:
	  (use "git add -f <file>..." to include in what will be committed)

		tracked/submodule/initial.t

Instead, we would want it to show the submodule in the "Ignored files"
section:

	On branch master
	Ignored files:
	  (use "git add -f <file>..." to include in what will be committed)

		tracked/submodule/

Makes sense.  Also listing the paths in the embedded working tree
like initial.t as if it were part of our project is utterly wrong,
especially because we are not doing any --recurse-submodules thing.

Both the change and the updated description looks good.  Thanks.
