Package: texlive-binaries
Version: 2009-6
Severity: important

Hi,

When $HOME contains a trailing "/", pdftex takes an absolute age to generate
a PDF file from a .tex source file.  It seems this problem has been reported
once before, in 2008, in Ubuntu, as per the following report:

https://bugs.launchpad.net/ubuntu/+source/texlive-bin/+bug/192877

This bug is still very present in today's version of TeX Live, so I am very
dubious about the claim that it's fixed upstream.  It's easy to reproduce --
just compare the following:

1.  HOME="$HOME/" time pdftex some_file.tex
2.  HOME="/home/$USER" time pdftex some_file.tex

Running number (1) above will result in pdftex sitting there with 100% CPU
and an ever-increasing load average.  On my machine it took ~36 minutes to
run.  Compared with (2) which took 0.9 seconds.

Note that this bug also affects installing TeX Live -- and in no word of a
joke, installing the texlive meta package took over 24 hours of a straight
run -- all because my $HOME has a trailing slash on it.

Note also that I do not override the system default value of what $HOME is
set to - so I would be very reluctant indeed to suggest that one should
change their $HOME to not contain a trailing slash.  Doing this in a shell
startup file simply spells disaster, so this bug needs fixing upstream
still.

This bug should be fixed with TL 2012 and later, as this is handled
in cthe current sources.

I also cannot reproduce your problem with a *very* big home directory
I have here.

Thanks, and all the best

Norbert
