I am looking at the code in https://github.com/CSAILVision/LabelMeAnnotationTool/blob/master/annotationTools/perl/fetch_image.cgi and keep seeing return statement being used outside of a function, like this
if(!open(FP,$fname)) {
print "Status: 404\n\n";
return; # <--- this one o_O
}
it repeats over an over again, e.g. at lines 24, 49, 74, etc
Perl would throw an error in such cases Can't return outside a subroutine .... Which is expected, because return is used to return from a subroutine and there are no subroutines defined in the whole script. Indeed, you will see the error message appear in apache error log if you try with a faked URL (note collection=empty that corresponds to no file)
tool.html?mode=c&collection=empty
What am I missing? Is it just a joke?
