I have gotten a few of these while testing:

A more complete one is attached (just more similar ones).

Attached is a script (test.sh) and a list of man page names (list) that

pruned some more, but I will try tonight again after some sleep ;)

Here is a test run (note that it do the same with symlinks instead of
hard links):

I am running 2.6-test2 kernel. Download the perl 5.8.0 (stable.tar.gz).
./Configure --prefix=/mnt/hdc3; make; make install.

It did not happen for me. Hash::Util.3 was installed correctly.
(Of course, I did turn on directory index)

Can you send me more infomation how you build the perl package
and install it? I guess I have to do more gentoo like step to duplicate
it :-)

Thanks

Chris

Re: [2.6] Perl weirdness with ext3 and HTREE

[Patrick McLean]

It is possible to install gentoo in a subdir of your main box, just 
unzip the tarball
into that directory, then chroot to it and follow the rest of the steps 
for installation
(skipping kernel, bootloader, syslog, etc of course), then you can test 
stuff out by just chrooting to the gentoo dir, and doing "env-update ; 
source /etc/profile".

It is all the file operations on that *directory* that matters.

Yep, did that.  I had a simple c program once that tried to
simulate all file operations on that file, and the 'real'
man page that gets installed.  Did not have the same effect
however.  Might be that I was off by something.  Don't have
it however anymore, as it was some months before, just before
I mailed the first time.

I am not claiming it is a gentoo issue. I just want to duplicate
this bug with minimal damage to my box.

OK, I will try the perl install first.

You can do a strace on the perl install, then grep for all
the file changes happen on that directory. There is a good
chance follow the strace log can duplicate the bug also.

I cannot really see that it is a Gentoo specific problem, but who knows.
I will try to get a CD of another distro somewhere, and get that on a
box to test - currently work/whatnot just keeps me pretty tied up :(
Another reason why I posted, is now that 2.6 is more widely used/tested,
its not only me that gets this, but other users as well - thus I hoped
that somebody with more time wanted to have a crack at it.

Back to the problem - on the same system, a 2.4 kernel works fine, but
a 2.5/6 kernel activates a race that creates an invalid entry.  I guess
the primary reason why not many people see this, is because most
non-Gentoo folk do not compile perl-5.8.0 from source.

Just grab the perl source, if you want, I can mail you the ebuild that
should give some direction in how to compile it, or grab your local
.spec, configure it (maybe with install location not in /), and then
just compile and finally install to a ext3 FS with HTREE enabled. 
Usually over here, it keeps on leaving an invalid entry to
..usr/share/man/man3/Hash::Util.tmp.

If it works fine (with a 2.6 kernel), I will go and bang my head against
a wall, and shutup until I can make time to try and track this - if not,
any ideas as to creating it outside the perl install (or rather the man
page part of the install process) would be great.

Re: [2.6] Perl weirdness with ext3 and HTREE

[Christopher Li]

I can take a look at it.

Is there any way to reproduce this bug without installing the
whole gentoo? It would be nice if I can just download some
package to make it happen.

Thanks,

Chris

[2.6] Perl weirdness with ext3 and HTREE

[Martin Schlemmer]

[-- Attachment #1: Type: text/plain, Size: 955 bytes --]

Hi

I have mailed about this previously, but back then it was not
really confirmed, so I have let it be at that.

Anyhow, problem is that for some reason 2.5/2.6 ext3 with HTREE
support do not like what perl-5.8.0 does during installation.
It *seems* like one of the temporary files created during manpage
installation do not get unlinked properly, or gets into the
hash (this possible?) and cause issues.

It seems to work flawless on 2.4 still.

Also, to be honest, I do not have that much free time these days,
so if an interest in helping me/us debug this, it will be appreciated
if some direction in what is needed/suggestions can be given as to what
is required.  There are a few users that experience this issue, and
I am sure that we can get whatever info needed.

A bug on our tracker is here with more (hopefully) complete info:

  http://bugs.gentoo.org/show_bug.cgi?id=24991
