[PATCH] stash: Add --clean option to stash and remove all untracked files

[PATCH] stash: Add --clean option to stash and remove all untracked files

[David Caldwell]

The --clean option acts like the normal "git stash save" but also adds all
untracked files in the working directory to the stash and then calls "git
clean --force --quiet" to restore the working directory to a pristine
state.

I find this useful for certain projects that need to run release
scripts. With this option I can run the release scripts from my main working
directory and not have to maintain a "clean" directory in parallel just for
releasing. Basically the work-flow becomes:

   $ git tag release-1.0
   $ git stash --clean
   $ make release
   $ git stash pop

"git stash" alone is not enough in this case--it leaves untracked files
lying around (configure and automake droppings, for instance) that might
mess up a release process that expects everything to be very clean.

Hi,

  This is my first patch to git so I have a couple questions:

  * I used 'find . -name ".git" -prune -o -print' to get a list of all the
    files in the working directory. That assumes ".git" is the name
    of the repo--is that assumption valid?

  * Also, that find command does not respect .gitignore. Should it? If it
    does then I think it would need another option to also clean up stuff
    that is normally ignored (similar to the way "git clean" works with the
    -x option). My thoughts were that if we were stashing everything, being
    overzealous with the cleanup wouldn't hurt (and would generally be
    exactly what you want).

Thanks,
  David

Hmm. I think I would call this something like "--untracked", as to me
the main function is saving those files, not cleaning them afterwards
(the fact that they are cleaned is really just making the untracked-file
handling in line with what we do for tracked files; we put the changes
in the stash and remove them from the working tree).

But that might just be me.

For that workflow, do you actually want the files saved and restored
via "stash pop"? That is, aren't those untracked files just useless
cruft that could be regenerated, and you would be just as happy to do:

  $ git tag release-1.0
  $ git stash
  $ git clean
  $ make release
  $ git stash pop

and have a pristine state after your pop? You end up regenerating them
during the next build, which could be costly. But you don't have to pay
the price of stashing potentially large files that are just going to end
up regenerated anyway. For that matter, what should this do with
gitignored files, like generated object files?

Also, wouldn't you want to "git clean" after your "make release" but
before your "git stash pop" in case the build creates cruft that is not
overwritten by your stash pop?

Hi David. Welcome to the list. :)

Please put your comments on the patch (i.e., anything not destined to go
into the commit message) below the "---" marker; that helps "git am"
know which part is which.

Generally yes, but somebody could do something tricky with GIT_DIR. You
should be using "git ls-files -o" instead.

I'm not sure of the answer to this. I think it would depend on your
workflow and your project (i.e., is your build system fragile enough
that you need to get rid of ignored build products between builds, or is
it OK to leave them, which is more efficient). I would think respecting
ignore would be a sane default, but I don't know if it should be
configurable, or have an extra command line option to stash everything.

If you do want to respect .gitignore, then you can add
"--exclude-standard" to the "ls-files" command I mentioned above.

When you apply this stash, what does the resulting index look like? Do
the untracked files remain properly untracked? That might be a good
thing to double check in the test script.

I see your point but I thought "--clean" was pretty descriptive of how
the working dir ended up afterward. Maybe "git stash --everything" (or
"--all")?

Yes, in that case you are right. My example was poor. I'm more worried
about junk that might actually affect the release but isn't
auto-generated. I'm usually too wary to run "git clean" because of the
random files I have sitting around--todo lists, random patches, new
files I haven't added but are sitting around possibly affecting tests,
things like that. I want them back at some point, but I want the
directory very clean when doing the release just to make sure I have
everything properly committed (so I could, for example, detect the new
source file that I forgot to add and commit).

Yes, you'd definitely want the git clean before the git stash pop. I
forgot that step.

Whoops. That was a copy and paste error. Took multiple tries to get git
send-email to work ;-).

Ah, thanks--I didn't know about that command! I was considering using
"git status --porcelain", but ls-files looks exactly like what I want.

The more I think about it the more I think you're right that it should
respect .gitignore on the default case and have another option to be
really thorough (even if my build system isn't always fragile, it's
sometimes nice to be overly cautious just for my own paranoid peace of
mind).

Perhaps --clean (or --untracked) respects .gitignore and --all just flat
out does everything?

They do in indeed, but you're right, that would be a good automated test
to add.

I personally think "--untracked" (and -u) is more intuitive too, since 
it tells you what "git stash" is about to do. i.e. "git stash" is about 
to do the usual stash operation *and* also stash the "untracked" files.
It seems more clear and precise than saying "git will stash my tree to a 
state that is clean", which doesn't exactly tell me how is that 
different from the usual stash.To me, "--clean" might even sounds more 
like "do a stash, and then do a clean", which doesn't make sense.

I would've liked "--all" too, except it reminds me too much of "git 
commit --all", which is just committing all tracked files.

Again, that's just my personal preference.

Really?

   $ git stash --untracked

sound like it stashes *only* untracked files. (That by itself may be a
feature that some people want; so far, I'm not among them.)

I would be happy with something that indicated "untracked files in
addition to the regular stash". I just think it should be about "add
these other files into the stash", not "end up in this directory state".

Something like "--untracked-too" fits that, but is horribly ugly. I also
think it makes sense to have some way of stashing everything, including
excluded files.  That could just be "-x" in conjunction with whatever
this option is (which matches "git clean"), or it could be a separate
option name (like "--all" or "--ignored").

Things like "git stash --all" or "git stash --thorough" indicate that
you are stashing more, but it's hard to remember what the "more" is.

So I don't have any brilliant suggestions. Doing:

  $ git stash --untracked-too --ignored-too

is fairly clear, but somehow strikes me as unnecessarily ugly and
verbose.

I think `--also-untracked` sounds better. It is even longer, though.

There could also be `--only-untracked`, which would stack only the
untracked files (and let changes of tracked files there).

This I think depends on how you view what stash does. If you concentrate
on the "saving" aspect too much, your naming would start from "untracked"
and end up to be that ugly thing. If you start from "what happens to the
working tree", on the other hand, --clean may not be such a bad name for
what it does.

But I think the previous point you raised about untracked-but-not-ignored
vs untracked-and-ignored is much more important. I do not think anybody
would want to put build products in stash and unstash them later, so in
that sense we can say we would only save the untracked-but-not-ignored in
the stash and remove them, but then "git stash --clean" (or whatever we
end up calling it) would still leave non-source material in the working
tree, which probably does not exactly the original motivation of wanting
to get a pristine source tree without having to trust the build procedure
(i.e. "make clean" may leave cruft behind).

Perhaps -uall to match git-status's -u[<mode>] option (and also the long
version thereof)?

"--include-untracked" sounds a bit smoother to my ears.

Me too. It's long, but it fits with other git commands.

[PATCH] stash: Add --include-untracked option to stash and remove all untracked files

[David Caldwell]

The --include-untracked option acts like the normal "git stash save" but
also adds all untracked files in the working directory to the stash and then
calls "git clean --force --quiet" to restore the working directory to a
pristine state.

This is useful for projects that need to run release scripts. With this
option, the release scripts can be from the main working directory so one
does not have to maintain a "clean" directory in parallel just for
releasing. Basically the work-flow becomes:

   $ git tag release-1.0
   $ git stash --include-untracked
   $ make release
   $ git clean -f
   $ git stash pop

"git stash" alone is not enough in this case--it leaves untracked files
lying around that might mess up a release process that expects everything to
be very clean or might let a release succeed that should actually fail (due
to a new source file being created that hasn't been committed yet).

Hi,

  This is a new version of the "git-stash --clean patch" I submitted earlier
  this week. The changes in this patch with respect to the old patch are:

    * changed --clean to --include-untracked
    * --include-untracked now respects .gitignore
    * added --all that does not respect .gitignore
    * changed the way untracked files get stashed so that when you "git
      stash apply" they remain untracked. I did this by creating a 3rd
      parent to the stash commit that contains only the unstashed files.
    * Added more tests to check --all and also whether untracked files
      remain untracked after apply.

Great you did it, that's indeed something I missed with git stash.

Shouldn't there be double quotes around $(untracked_files)?

I first thought of --all as a complement of --include-untracked, but in
your proposal, a simple

  git stash --all

is accepted. If you go this way, maybe there should be more symetry in
option naming. For example, --all could be --include-ignored.

Or you can consider that --all is short and sweet, and go for it ;-).

The --include-untracked option acts like the normal "git stash save" but

"git stash" alone is not enough in this case--it leaves untracked files
lying around that might mess up a release process that expects everything to

to a new source file being created that hasn't been committed yet).

Yes there probably should be. It is corrected in this patch.

The problem with --include-ignored is that it doesn't read to me as if the
untracked files are included too. It should technically be
"--include-untracked-and-ignored". "-all" seems like a better alternative to
me.

Just a minor nit from internal API point of view, I would prefer to see
something like

	create_stash --untracked=all "message"

or even

	create_stash --untracked=all --message="message"

once you start enriching these functions with optional behaviour.

Currently I'm playing with --include-untracked (-u) and --all (-a) while I 
fix a bug I found in the patch. I agree that --untracked sounds like it's 
only stashing the untracked files which isn't the case. I wasn't going to 
have an option to stash *just* the untracked files because I can't come up 
with a use case that makes sense. I still like "--clean", too.

-uall (like git status) isn't really the same thing which I think is 
confusing since it has the same name.
