Re: Test fails on ubuntu breezy

I've recently encountered the same problem with t/t3600-rm.sh step 9,
but I put it down to compiling as root.

Basically, the chmod of the directory didn't stop the delete from
happening, since I had umask 002 and it was g+w.

Anyway, that test is fragile.

Indeed.  I am not sure about test #5, but here is my stab at
fixing test #9.

[PATCH] t3600-rm: skip failed-remove test when we cannot make an unremovable file

When running t3600-rm test under fakeroot (or as root), we
cannot make a file unremovable with "chmod a-w .".  Detect this
case early and skip that test.

I am still having failure with the top of the tree. I guess it is
because git rm exit with status 0.

kvaneesh@home:/tmp/test$ git rm -f a
rm: cannot remove `a': Permission denied
kvaneesh@home:/tmp/test$ echo $?
0

Please don't guess, but validate (I know you are capable of
doing so).

What I would do to see what is happening would be to do
something like the attached patch and re-run the test.

BTW, you did "sh -x t3600-rm.sh" which is very good.  I usually
do it when debugging hard-to-debug testsuite problem, especially
ones which I do not know intimately, written by somebody else,
like this:

	sh -x tXXXX-that-test.sh -i

The -i option makes it immediately stop at the first test failure.

I did :). I sent another mail explaining it is xargs in breezy. I also
filed a bug. But they are not going to fix it in breezy. The below is
the response i got.

"As Ubuntu Breezy is a released probuct, only security-related fixes
are accepted. If you think this fix is important enough, you could
discuss the issue with the maintainers of Ubuntu backports, and see if
they are interested in making a backport available: "

Right now i am commenting out the test case to build the .deb file.

I think it is xargs
kvaneesh@home:/tmp/test$ echo a | xargs rm
rm: cannot remove `a': Permission denied
kvaneesh@home:/tmp/test$ echo $?
0
kvaneesh@home:/tmp/test$

on ubuntu Dapper it returns 123 status.   I will file a bug report
against xargs.

On solaris 10 too, only test 5 also fails.
