[Octave-bug-tracker] [bug #49779] print /non/existing/dir/file.svg crashes octave

[Pantxo Diribarne]

Follow-up Comment #8, bug #49779 (project octave):

@Rik: I agree that in many cases using exception instead of carefully checking
input is a simpler approach, but in this case, even when we manage to rethrow
exceptions from the GUI thread, it means gl2ps will spend eventually a lot of
time preparing an eps that can't be written or converted. Imagine


demo light 3
print -dpgn toto.png
print /non-existing/toto.png
print locked-file.png


Anyone of those print commands will lead to an error *after* 37s on my rather
new computer when we could have had it return an error early.
