Frank Küster has rewritten texdoc in luatex and now it really works much better than the original one.

Good to here that!

Well, searching the whole disk with find when we have ls-R databases was a strange approach, no? The next Debian packages of luatex (as soon as you release a new beta ;-) will ship the lua version of texdoc instead of the default texlive texdoc.

Furthermore, a call to securly create a tmp dir would be nice, too.

I agree, and will happily add it. mkstemp() doesn't help though, as it only works for files. I'll have to borrow or write a version of BSD's mkdtemp, somehow.

The is probably the best idea, since relying on a lib function which might not exist is a problem.

Yes, otherwise it would be racy, some other process could make a symlink attack whatever you have in your home dir.

needed; i wonder, maybe it makse sense to accept an optional argument that for the root so that one can generate a tmpdir at a specific location i.e. tmpdir("/tmp") or so

mkstemp and mkdtemp (section 3) allow for templates. Or the shell function mktemp allows for templates and creation of dirs/files. But are mkdtemp and mkstemp available everywhere we want to compile luatex? The man page of mkdtemp(3) is not very inviting: VERSIONS Available since glibc 2.1.91.

For this reason, ld(1) will output a warning message whenever it links code that uses mktemp().

The mkdtemp() and mkstemps() functions are non-standard and should not be used if portability is required.

Hmm, so there is the option between portability and security, grrrrr.

That's why I wrote:

conf'ing for something that only exists in some specific BSD's is not worth the effort (unless it can reliably be added to openbsdcompat).

The original openssh-openbsd-compat has #if !defined(HAVE_MKDTEMP) || defined(HAVE_STRICT_MKSTEMP) int mkstemps(char *path, int slen); int mkstemp(char *path); char *mkdtemp(char *path); #endif Best Martin
