[Resend PATCH] package: Makefile: fix perf target bug

[mfmooney]

From: matt mooney <mfm@muteddisk.com>

Specify --git-dir and --work-tree when building perf targets to
allow out-of-tree builds using O=<build-dir>.

The cat command had to be changed to allow proper file name expansion
of the files listed in MANIFEST.

Hi Michal,

Sorry if you have already received this, but there seems to have been
a problem when it was first sent.

Thanks,
matt

Neither git archive not git rev-parse need the work tree, --git-dir=..
is sufficient.

Are you sure? --git-dir points to the .git directory and --work-tree
points to the actual source code directory. Both are needed when you
are out of the source tree and the .git directory is not really
located at .git from the $PWD.

From an empirical standpoint, this as well as any git command that is
issued from outside of the working directory fails to function
properly without --work-tree.

You are right about that command, but it doesn't use the source tree.
Do a git --git-dir=$HOME/linux-2.6/.git status from /tmp and see what
happens.

So do you want me to send a new patch without --work-tree= in git rev-parse?

Okay, so I decided to just go ahead and send this. It removes the --work-tree
option from the git rev-parse command. I did test it the way you said, without
--work-tree on either statement, but the git archive command fails in that case.

Thanks,
matt

Yes, neither git rev-parse nor git archive use the work tree. That's 
what I tried to explain to you in my first mail.

That's irrelevant, I only talked about archive and rev-parse.

And in git archive.

Okay, again you are right; I erroneously thought git archive needed
the work tree too.

So the real problem is that tools/perf/MANIFEST contains wildcards,
and when git archive is run, file name expansion isn't working
properly. By adding the $(srctree) as a prefix, globbing works but
then git archive requires --work-tree to be set.

I really don't know of a better alternative.

matt

I see. So how about
git --git-dir=$(srctree)/.git archive ... \
    $$(cd $(srctree); echo $$(cat tools/perf/MANIFEST))
? That does exactly the same as before the patch, just changes to
$(srctree) so that the expansion works.

Sure that works too! I guess it is less invasive than my original
change. I will fix that up and resend it.
