We all know "eval" is actually two completely different operations. eval "" (string) parses perl, whereas eval {} just catches exceptions.

I'm trying to use Safe to protect against eval of strings, but allow the use of eval for catching exceptions (in other words, allow "entertry" and forbid "entereval").

By default, Safe protects you from "entereval" (eval of a string). However this script breaks on eval {} - which is for catching exceptions.

Why does Safe think the use of eval {} is actually eval of string? Is there a way I can use safe while permitting catching of exceptions?


use strict; use Safe; my $SafeCompartment = new Safe; $SafeCompartment->permit(qw(entertry)); my $evalbrace =' eval { 1 } ; '; $SafeCompartment->reval($evalbrace, 1); if ($@) { die "WARNING!: evalbrace failed: $@"; } ./testsafeexecute WARNING!: evalbrace failed: eval "string" trapped by operation mask at + (eval 2) line 2.
Basically I want reval(' eval "code"; ') to fail and I want reval(' eval { 1 }; ') to succeed.

In reply to Safe.pm is broken - entertry fails by dtreder
