mtxrun --script fonts --reload: Question to behaviour

mtxrun --script fonts --reload: Question to behaviour

[Tomas Hala]

Hi all,

doing some test with fonts I discovered that 

mtxrun--script fonts --reload

crashed (line 479, TL 2018) on existing directory if this directory has
incorrect permissions (in tested case I set 000 for making the directory
and its subtree completely invisible).

Is this the expected behaviour?

Best wishes,

Tomáš

ok, but  as far as I can see it's not a crash,
it's just an error like "open file foo"  when  you have not the right
permissions on foo.
In other words: mtxrun  doesn't have  the right permissions in that folder
so it' correct that it stops
*and* exits. If it stops and hang forever, of if it stops with a seg.
fault,  then it's an error,

I understand the explanation, thank you. But why it stops? I can imagine the
behaviour with skipping inaccessible directories (eg. with some warning
messages)... Is there any way how to persuade it to continue the work?

hm, dunno, it's a lua script, perhaps you can hide these errors,
but  to me the current behavior is ok, because when I see this error
I know the *I* am doing something wrong that I need to fix.
