It's now showing up as untracked because Git doesn't know about it. Similarly if you just did 'git stash push' without --keep-index, 'file' would be restored in your working tree, but 'git status' would report the working tree as clean because it would also be restored in the index. > Expected: > `git status` gives this output: > > On branch master > > Changes to be committed: > > (use "git reset HEAD <file>..." to unstage) > > > > deleted: file This is what you get before 'git stash push --keep-index'. Do you think the documentation on '--keep-index' is unclear, and could be improved? Or why did you think that this is the correct output? > Verified on: > + Windows 10, git version 2.21.0.windows.1 > + Ubuntu 14.04, git version 2.21.0 ^ permalink raw reply [flat|nested] 4+ messages in thread

Now that you explained this, I do understand the behaviour, and agree that it is correct. While this seems to be clear with a deeper understanding of git than I have, it might be a good idea to specifically point this out in the docs in the context of `--keep-index`. That would have helped me. This does, however, bring me back to a related issue by which I stumbled across this: If, in the given scenario, I run `git stash apply`, the file is not removed. `git status` still outputs this: > On branch master > Changes to be committed: > (use "git reset HEAD <file>..." to unstage) > > deleted: file > > Untracked files: > (use "git add <file>..." to include in what will be committed) > > file Can you explain that behaviour as well? The way I understand it, `git stash push --keep-index; git stash apply` should result in zero change to the output of `git status`. What am I not getting? ________________________________________ From: Thomas Gummerer <t.gummerer@gmail.com> Sent: Tuesday, April 16, 2019 20:48 To: Christian Vetter Cc: git@vger.kernel.org Subject: Re: [BUG] git stash --keep-index undeletes file On 04/16, Christian Vetter wrote: > Steps to reproduce > + mkdir git-stash-test > + cd git-stash-test > + git init > + touch file > + git add file > + git commit -m init > + git rm file > + git stash push --keep-index > > > Result: > `git status` gives this output: > > On branch master > > Changes to be committed: > > (use "git reset HEAD <file>..." to unstage) > > > > deleted: file > > > > Untracked files: > > (use "git add <file>..." to include in what will be committed) > > > > file I think this is the correct result. --keep-index keeps the changes that are in the index, in this example that 'file' is deleted, but restores the working tree to 'HEAD', where 'file' existed.

On second thought, I might have been too quick to jump to conclusions here, and might have misunderstood --keep-index myself. I think what you described here is actually a bug, although it's a pretty long standing one. So I'm a bit surprised nobody noticed it before. Thanks for reporting it. > This does, however, bring me back to a related issue by which I stumbled across this: > If, in the given scenario, I run `git stash apply`, the file is not removed. `git status` still outputs this: > > On branch master > > Changes to be committed: > > (use "git reset HEAD <file>..." to unstage) > > > > deleted: file > > > > Untracked files: > > (use "git add <file>..." to include in what will be committed) > > > > file > > Can you explain that behaviour as well? > The way I understand it, `git stash push --keep-index; git stash apply` should result in zero change to the output of `git status`. > What am I not getting? Your interpretation of what should happen sounds like the right behaviour here, and what actually happens seems incorrect. I don't have time to dig into this more right now though unfortunately. > ________________________________________ > From: Thomas Gummerer <t.gummerer@gmail.com> > Sent: Tuesday, April 16, 2019 20:48 > To: Christian Vetter > Cc: git@vger.kernel.org > Subject: Re: [BUG] git stash --keep-index undeletes file > > On 04/16, Christian Vetter wrote: > > Steps to reproduce > > + mkdir git-stash-test > > + cd git-stash-test > > + git init > > + touch file > > + git add file > > + git commit -m init > > + git rm file > > + git stash push --keep-index > > > > > > Result: > > `git status` gives this output: > > > On branch master > > > Changes to be committed: > > > (use "git reset HEAD <file>..." to unstage) > > > > > > deleted: file > > > > > > Untracked files: > > > (use "git add <file>..." to include in what will be committed) > > > > > > file > > I think this is the correct result. --keep-index keeps the changes > that are in the index, in this example that 'file' is deleted, but > restores the working tree to 'HEAD', where 'file' existed.
