note clinton Hi Mark <p>I've got the same misgivings about [mod://File::MMagic] and [mod://File::MMagic::XS] as you. [mod://File::MimeInfo::Magic] looks like a nicely written module, but I'm concerned about using it in my mod_perl app, because loading the module plus the magic data consumes 2-3MB of memory - memory which will become less shared with time because it lives in Perl rather than in a library.</p> <p>[mod://File::LibMagic] is an XS interface to <c>libmagic</c> and, while it still loads 1.6MB of data, that data can be shared between children. It's not a great interface though.</p> <p>I'm considering just using a system call to <c>file</c>, and lose a bit of performance in order to save some memory as, in my case, these mime-type checks happen seldom.</p> <p>Clint</p> 693367 693367
