Package: texlive-base Version: 2015.20150703-1 Severity: normal Dear Maintainer,
There is a potential race condition in the mktexdir program. If two instances of mktexdir try to create the same directory simultaneously, one may error with, for example, mkdir: cannot create directory ‘././home/mike/.texmf-var/fonts/pk/ljfour’: File exists I can easily demonstrate this by repeatedly running a simple script such as $ rm -rf ~/.texmf-var && \ ( /usr/share/texlive/texmf-dist/web2c/mktexdir \ ~/.texmf-var/fonts/pk/ljfour/jknappen/ec || echo "FAIL: $?" ) & \ ( /usr/share/texlive/texmf-dist/web2c/mktexdir \ ~/.texmf-var/fonts/pk/ljfour/jknappen/ec || echo "FAIL: $?" ) mkdir: cannot create directory ‘././home/mike/.texmf-var’: File exists FAIL: 1 Specifically, this can occur in a parallel build of Texinfo documentation when the dvips and texi2pdf commands happen to run simultaneously. If the font cache directory does not already exist, e.g. buildd environment, both programs will try to create it and this error can occur. Refer to Ubuntu buildd log of octave [1] for a real-world occurrence. I have not been able to reproduce on my own, only by digging down through the TeX stack and running low-level utilities mktexpk or mktexdir as in example shown above.
