From occitan@esperanto.org

I have added a new feature and regression test to makepp.sf.net, and this new
test is mysteriously failing with every version since 5.8.9 & 5.10.1 (some
32bit, some 64, some ActiveState, some self compiled), but not with 5.10.0 and
older ones. This only happens, but reproducibly, when the test is running on
NTFS, be it Ubuntu's fuseblk mount of /host to the underlying Windows XP D​:,
or when I create an NTFS on Linux and mount it directly.

What all tests do is, create a subdirectory, unpack the test into it, chdir
there, perform the test, chdir back and File​::Path​::rmtree the subdirectory.
Now all newer perls are saying "cannot remove path when cwd is
/.../loop.tdir". Before calling rmtree, I have checked the return value of
chdir, logged Cwd​::cwd, even put in a sleep and checked /proc/<pid>/cwd and
they all agree that this is not true.

What is special about this test is that it forks, the child execs perl makepp
with the new --loop option (which makes it repeatedly kill 'STOP', $$) and the
father does waitpid $pid, WUNTRACED; kill 'CONT', $pid a couple of times (how
many has no effect on the problem). Finally it kills the child and waits for
it (and it really is gone before the test ends).

Now I'm sorry to say, I've tried to write some minimal scripts to reproduce
this, but they failed to. Only if the child actually runs makepp does this
happen. So if anybody has the courage to, grab today's check in as per
http​://sourceforge.net/scm/?type=cvs&group_id=43679&source=navbar and

cd t
./run_tests.pl loop.test

Looking at this ticket this evening, I had occasion to try that link. I got​:

#####
There was an error processing your request ...

Is there a better link? Are the issues raised in this ticket still a concern?

Thank you very much.

It should redirect you to the new SourceForge URL structure, as it does
for me​: http​://sourceforge.net/p/makepp/code/?source=navbar

Near as I can figure, (at the time of this writing) you can get a dump
of the directory as it was at the time of the creation of this ticket by
doing

cvs -d​:pserver​:anonymous@​makepp.cvs.sourceforge.net​:/cvsroot/makepp export -D 2013-01-21 makepp

Should a tarball of that be attached to the ticket for future reference?

That shouldn't be necessary. Any recent version from
http​://sourceforge.net/projects/makepp/files/2.1/snapshots/ can reproduce
this. Just unpack, go to the t/ directory and run either​:

./run_all.t loop.test
/some/perl ./run_all.t loop.test

I just saw something strange. All the versions up to 5.20.0 which I compiled
in a standard way (except for --prefix) show this behaviour. But the 5.18.2
which comes with Ubuntu 14.04 doesn't show the problem. Probably one of their
many patches does the trick​:
