mtxrun --script fonts --reload: Question to behaviour
![](https://secure.gravatar.com/avatar/9c54554cf31b1a1894f2a3420f0ebbc1.jpg?s=120&d=mm&r=g)
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

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).
what do you mean with "crashed" ? -- luigi

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, -- luigi

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? Tomáš

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. -- luigi
