 It seems to me that git-ls-files is what you want here:
   git ls-files -i --exclude-standard

Ah-hah, that does what I want, and indeed it shows that we've got some
issues.  Working on cleaning them up.  Thanks!

git clean -nx shows you all ignored files that are not checked if thats what 
you want...

[HACKERS] Easy way to verify gitignore files?

2010-09-22 Thread Tom Lane
It's not hard to tell if we're missing a file that ought to be listed
in .gitignore --- git status will find that problem soon enough.
However, it seems that git isn't so willing to tell you about gitignore
patterns that cover too much, i.e. match files that are already in the
repository.  I found out by accident that you will only hear about this
when you try to git add such a file after changing it.  This seems
pretty dangerous, especially for people who are willing to rely on
git commit -a :-(

Is there any automated sanity check that we can run to find this sort
of problem?  I suspect that we probably have got some errors in the
.gitignore files, particularly in the back branches, and it would be
nice to find them now before they get in the way of normal development.

 However, it seems that git isn't so willing to tell you about gitignore

 git commit -a :-(

I assume one could write a perl script to check this pretty simply...

No doubt, but I was hoping somebody already had.  In particular, it'd
be best if one could use git's own logic for matching .gitignores,
rather than reimplementing it in a way that might or might not behave
quite the same.

treated like any other file.

There is no danger. git commit -a will commit changes to files that
match .gitignore but are already in the repository. (I vaguely remember
that there were bugs in this regard in old versions of git, but it's not
a problem with any recent version AFAIK.)

Right; .gitignore patterns are only applied to untracked files.  Once
a file is tracked by git, you can try to gitignore it all you like, it
won't have any effect.

I can demonstrate that this is not so.  Try a git add on such a file.
It fails --- at least it does with the version of git currently in
Fedora 13.  You get some nasty warning about how there's a conflicting
.gitignore pattern and you have to use -f if you want to add.

Works fine for me with v1.7.3 (no warnings, no need for add -f). What
version do you use?

If I try to add an untracked file which is already ignored, then I get
the warning.
