File::Temp::HIGH setting causes t931 test to fail

[veprbl]

Here is a full build log

After patching

LaTeXML/t/931_epub.t

Line 28 in be6bbab

my $pid = open3($writer_discard, $reader_discard, $error_discard, @invocation);

to be something like

my $pid = open3($writer_discard, '>&STDOUT', '>&STDERR', @invocation);

We can see errors like

Error in tempdir() using /data/tmp/nix-build-perl5.34.0-LaTeXML-0.8.6.drv-0/XXXXXXXXXX: Parent directory (/data/tmp/nix-build-perl
5.34.0-LaTeXML-0.8.6.drv-0) is not safe (Sticky bit not set on /data when dir is group|world writable) at /data/tmp/nix-build-perl5.34.0-
LaTeXML-0.8.6.drv-0/LaTeXML-0.8.6/blib/script/../lib/LaTeXML.pm line 196.

And changing ownership of temp directories is not always an option (this is also observed when they are created by our package manager Nix, as a part of a sandbox).

I wonder if it would be acceptable to change the setting to a less restrictive File::Temp::MEDIUM, especially in the light of Perl-Toolchain-Gang/File-Temp#36

Curious... Could you confirm that setting it to MEDIUM fixes the issue on your setup @veprbl ?

@dginev Yes, I did test that setting and it works.

@dginev Thank you!
