why does git perpetually complain about include/asm-blackfin/macros.h?

why does git perpetually complain about include/asm-blackfin/macros.h?

[Robert P. J. Day]

  for the umpteenth time, after doing a pull, i see this:

$ git diff
diff --git a/include/asm-blackfin/macros.h b/include/asm-blackfin/macros.h
deleted file mode 100644
index e69de29..0000000
$

  this happens constantly.  what's going on with this file?

I have the same problem.  git 1.5.0.6 on Fedora Core 5 or 6.

I even tried a completely fresh clone, but the problem still appears.

I've seen that as well, but in my case doing a
$ git reset --hard master
fixed it.

Sure.  git checkout -f fixes it too.

But then it reappears the every time I switch branches.

same here -- checkout fixes it, but back it comes after the next pull.
not fatal -- just annoying.

Do some of your branches miss the commit by which it was removed?
(It was removed in df30b1171714bbf0e55ffe02138be4b8447e4235)
Than it will reappear every time you switch to a branch which still has
the file.

It is somewhat unclear what "reappear" means, though: do you mean
in your working directory (that's what I explained above) or do you
mean: on the commit pointed by HEAD?

In that second case I can only suspect that all your branches point
at the same commit, which is just before the one the file was removed
in...

_Not_ the same. Just some commit before the file was removed, of course.

The problem is that this commit didn't delete the file, but truncated it
to zero size. How it got to be like that is another matter. Within the
kernel zero sized files are not supposed to be there, by widely accepted
practice. So lots of tools assume they should delete them!

[PATCH] Blackfin arch: include/asm-blackfin/macros.h die die die

[Marco Roeland]

This file accidentally got truncated instead of deleted in commit df30b11.
Doing a "make distclean" or "make mrproper" deletes this file because of
its zero size. Git then sees this as an uncommitted local change.

git-clone followed by git-checkout master recreates the problem.

But to answer your question directly, I rebase, so they absolutely do 
not miss any commits.


> It is somewhat unclear what "reappear" means, though: do you mean

Attempts to give you precise output to answer your question yielded a 
data point, the kernel's "make distclean" causes this:

[jgarzik@pretzel linux-2.6]$ make distclean && git checkout master && 
git diff HEAD
D       include/asm-blackfin/macros.h
Switched to branch "master"
diff --git a/include/asm-blackfin/macros.h b/include/asm-blackfin/macros.h
deleted file mode 100644
index e69de29..0000000

[jgarzik@pretzel linux-2.6]$ git checkout -f

[jgarzik@pretzel linux-2.6]$ make distclean && git checkout master && 
git diff HEAD
D       include/asm-blackfin/macros.h
Switched to branch "master"
diff --git a/include/asm-blackfin/macros.h b/include/asm-blackfin/macros.h
deleted file mode 100644
index e69de29..0000000

[jgarzik@pretzel linux-2.6]$ git checkout -f

[jgarzik@pretzel linux-2.6]$ git checkout master && git diff 
HEADSwitched to branch "master"

[jgarzik@pretzel linux-2.6]$ git checkout master && git diff HEAD
Switched to branch "master"

[jgarzik@pretzel linux-2.6]$


So, not a git problem but a kernel Makefile problem.  Sorry for the git 
noise.

distclean on purpose delete zero size files.
And the kernel tree shall not contain such files - if it does it is a bug.

So I do not see a 'problem' with the kernel makefile but instead a problem
with the kernel tree wich is about to be fixed.

Agree?

Dangerous, as it may overwrite local changes you have! A simple "git
checkout include/asm-blackfin/macros.h" is much safer in this case.

In git commit df30b11 this file got redundant. Perhaps because a normal
patch was applied, instead of with git, the file didn't get deleted from
the repository but truncated to size zero. Not strictly wrong perse, but
for the Linux repository highly unusual (and the only one at that).

Your toolchain perhaps deletes files with zero size after cleaning up or
something. Git then notices that you deleted this file.

Perhaps someone can apply something like the following to finally fix
this up:

commit 7d98740800f3d9ad2428afa8c677be9573a51b7b

Git complains for a very simple reason: that file is an empty file, and 
"make clean" removes all zero-sized files.

So whenever anybody does a "make clean" (maybe it's "make distclean", I 
forget), you will have removed the empty file, and git will show it as a 
diff.

We probably should just remove the file from the kernel archive.
